Description

Air handling system

This invention relates to air handling systems, and more particularly to a portable room air filtration system.

The popularity of air handling systems continues to grow, as concerns about air quality have always been a major issue. This growth has led to an increase in the use of commercial and domestic air handling systems. A conventional domestic air handling system is a self-contained unit that can be placed in a room where it is desired to handle its air. The operation of a domestic air handling system is generally accomplished by drawing room air into it, treating the air with one (or more) techniques, and releasing the treated air back into the room. The treated air generally contains a lower concentration of airborne pollutants than the air in the room. The treated air is mixed with room air and thus the concentration of contaminants in the room air is reduced.

Air handling systems with different types of control systems are currently available. The control system provides different methods for controlling the operation of the air handling system and for allowing operator input. The design and configuration of the control system can have a major impact on the functionality and aesthetic appeal of the air handling system.

Many traditional air handling systems include a range of special filters that are tailored to address specific air quality issues. For example, domestic air handling systems often include a front filter, a particulate filter, and an odor filter. The function of the front filter is generally to remove relatively large components from the air, such as mucus such as hair and dust. Particulate filter It is generally necessary to function to remove smaller airborne particles. The particulate filter has a wide variety of configurations. For example, a particulate filter can include a pleat material having non-woven fibers that pick up particles and can be effective as a HEPA filter. Odour filters are also available in a wide variety of configurations and configurations. Many odor filters include activated carbon that absorbs a range of impurities including, but not limited to, a variety of organic chemicals. Conventional particulate filters and carbon filter appliances have a limited life span and require frequent replacement. The air handling system, as well as the mechanism used to secure the filter in the air handling system, can have a significant impact on the efficiency of the system and can greatly affect the complexity and effort required to replace the filter.

There are other aspects that can impact the functionality and commercial success of an air handling system. For example, convenient features, such as power line management, and mobility features such as, for example, tripods and handles, can affect user experience.

The present invention provides an air treatment system (ATS) having an improved control system. In one embodiment, the control system includes a "control plane" display that provides a simple look of the ATS and facilitates an improved control experience. The display can include a plurality of informational display elements and a plurality of touch sensors, selectively illuminated by a configuration of a plurality of concealed light sources, such as, for example, LEDs/LEDs. To generate the desired pattern, each light source can be covered by a spacer having a mask layer and a diffuser layer. A half of the transparent cover can be placed over the control system to hide the concealed structure and allow the graphical image to be seen only when illuminated. The translucent cover can be integrated into a detachable front cover that encloses the front of the ATS. In one embodiment, the electronic component module includes a light pipe assembly having a plurality of individual conduits arranged side by side to direct light from the light source to the corresponding display component.

In one embodiment, the touch sensor is a capacitive sensor. This concrete In the embodiment, a capacitive film, such as a transparent PET film coated with indium tin oxide, can be integrated into the structure covering the respective light sources. For example, each light source can be covered by a laminated separator that includes a mask layer and a diffuser layer, and the capacitive film can be implemented as an additional layer of the spacer. As another example, a capacitive film can be separated from the spacer and can be placed over or under the spacer to sense the presence of an operator's finger. In an alternative embodiment, the conductive traces can be integrated into the structure covering the various light sources to function as a capacitive sensor. For example, a printed circuit board (PCB) can be placed over an array of light pipes. The PCB can define an opening over each of the individual light pipes and can include a line wrap around each of the openings associated with the light pipe for an input display element. The PCB may also include a relatively large conductive trace that extends over most of the surface of the PCB to provide a capacitive sensor that is sensitive enough to function as a proximity sensor. The proximity sensor can be configured to sense the presence of a user (eg, a user's hand) within two inches of the display.

In one embodiment, the ATS has a detachable front cover covering the display, and the control system is configured to recognize the touch in different ways depending on whether the cover is mounted or removed. This allows a user to control the system regardless of whether the cover is in position or not. In a specific embodiment, the control system is configured to enable a different set of control options depending on whether the cover is installed. For example, the control system can provide a reduced set of control options and/or provide additional control options when the cover is removed. The control system can use one or more capacitive touch sensors, such as, for example, proximity sensors, to identify whether the cover is installed or removed.

In a specific embodiment, the control system can include a dust sensor integrated into the electronic component module. The dust sensor can be arranged such that a portion of the vacuum actually caused by the ATS blower is drawn into the dust sensor. After passing the dust sensor, the air passes through the Wait for the filter and return to the room in the processed state. Alternatively, the dust sensor can be arranged such that the air stream from which the air is actually released by the ATS is drawn into the dust sensor.

In another aspect, the present invention provides a front cover having a magnetic interlock that allows for easy installation and removal and allows the control system to recognize whether the cover has been installed. In a specific embodiment, the front cover includes one or more mechanical attachment points at the top end and one or more magnetic attachment points at the bottom end. The mechanical attachment points can include a corresponding configuration that is configured to snap into the ATS housing. For example, the port can be snapped onto the electronic component module to assist in ensuring true alignment between the front cover and the electronic component module. The size, shape and configuration of the buckle can vary. For example, it may extend generally across the width of the front cover or it may extend only beyond a central portion of the front cover. As another example, the mouthpiece may be integrally formed with the front cover, or a separate component may be adhered to the front cover after manufacture. The front cover can be made of a semi-transparent plastic that is configured to provide an opaque appearance while allowing light from the display to illuminate. In one embodiment, the exposed face of the front cover can be covered by a film, which is performed using a mold film process. In another embodiment, the exposed side may be covered with a thin layer of lacquer using a spray process or a direct transfer process (such as serigraphy or pad printing, or hot film transfer). Alternatively, the front cover may be substantially opaque and may include a window covering the display. The window can be made of a half transparent plastic that is configured to provide an opaque appearance while allowing light from the display to illuminate. In one embodiment, the exposed side of the window can be covered by a film, which is carried out using a film-forming process. In another embodiment, the exposed side of the window can be covered with a thin layer of lacquer using a spray process or a direct transfer process (such as serigraphy or pad printing, or hot film transfer).

In another aspect, the present invention provides an ATS housing having a replaceable base. The number and type of pedestals may vary, but a specific embodiment of the ATS may include a plurality of pedestals Different configurations are provided for receiving wires, and/or different legs for supporting the ATS. As for the wire, the ATS may be capable of receiving a pedestal having a structure for manually winding a wire or a retractable wire set having an automatic rewind spool. As for the stand, the base may include a fixed stand, a caster, a runner, and/or a separate elongated roller. As an alternative to the detachable base, the base can be integrated into the base of the ATS and can include a stand and a separate elongated drum. The ATS can include a handle behind the top end of the housing. In one embodiment, the handle extends substantially the entire width of the ATS, thereby permitting the center of the ATS to be grasped with one hand or the opposite side of the hand with both hands.

In another aspect, the present invention provides a filter holder assembly that provides for an easy and secure mounting of the filters. In this particular embodiment, the ATS includes a specific filter and an activated carbon filter. The activated carbon filter is first snapped into the filter housing and the particulate filter is then snapped over the filter housing over the carbon filter. The particulate filter is secured to the ATS housing by one or more fasteners on its circumference that interact with corresponding structures in the ATS. The one or more fasteners are configured to securely clamp the particulate filter to the carbon filter in a cam-like manner. The ATS can also include a front filter that is crimped to the particulate filter. The front filter may comprise a coarse filter medium supported by a lattice front filter holder.

The present invention provides an improved control system for an ATS. Use a self-contained electronic component module to allow ATS installation and assembly to test and calibrate the electronic components. This practice can also help to replace the electronic component module when necessary. For example, using an on-board dust sensor with integrated tubing removes the need to separately install a dust sensor and wire the dust sensor to the electronic component module. The control system includes an "electroless board" display having an integrated capacitive touch sensor. This allows for a fully sealed electronic component module without any moving parts, providing improved reliability. The use of an "electroless board" display allows a dynamic display Transforming between modes - not only provides improved aesthetics, but also simplifies the display to facilitate easy operation from one mode to another. The use of light-emitting diodes (LEDs) with multiple color or brightness options allows the display elements to be illuminated depending on the configuration used. Wireless connectivity allows remote control (such as smart phones and tablets) to control and exchange data, including data logging and historical trending, without the need for visible illumination or infrared-transparent plastic. Radio Frequency Identification (RFID) tags provide improved filter life and product performance tracking and allow filter life to be reset without user intervention. Dust sensors can be used to control not only the blower speed but also the more accurate filter life calculations. In another view, the ATS includes a front panel that can be easily removed and installed with one hand, without the need to bend the waist very low or squat to reach the attachment point. The front cover can cover the electronic component module to provide a "electroless board" display by at least partially translucent or partially translucent windows. Further, the side and center air inlets allow air to enter the ATS freely. In another view, the provision of a detachable base allows the ATS to be easily tailored to different applications and customers with different preferences. This provides more flexibility and a quick exchange between modules with different characteristics. For example, the type of tripod can vary and the type of wire management features can vary. The use of a one-piece handle that extends substantially the width of the ATS provides various advantages. This provides an operator to manipulate the ATS with one or both hands at multiple wrist/palm angles. This can also be done to provide structural reinforcement under the cantilevered features of the ATS. In one embodiment, the base may include a caster or a center roller that allows the ATS to be easily removed with a single hand snapped into the center of the handle. In another aspect, the present invention provides a simple and effective clamp configuration for securing a particulate filter to an ATS. By placing the clamp against the top of the filter and grasping the bottom end, the filter can be fixed or released without substantial bending or squatting. The one or more clamps can provide an improved seal by automatically pulling the filter closer to the sealing surface. The one or more fixtures may also only Work in one direction, thus ensuring that the filter is installed in the correct orientation.

B. General construction

As described above, the description of the present invention is based on an indoor air handling system that operates a blower (56) to move air through a series of filters (100, 102, 104) to perform its general function. The air treatment system (10) of the depicted embodiment is configured to process air in three stages. The first stage is a coarse pre-filter (100) intended to remove large contaminants such as hair, batt fibers and large dust cohesives (eg, "dust mass"). The second stage of filtration is a particulate filter (102). While the specifications of the particulate filter (102) may vary, the depicted ATS (10) includes a pleated HEPA filter media that reduces idle particles as small as 0.009 microns. The third stage of filtration is an activated carbon filter (104) comprising particles that have been coated with different catalysts. A bed of activated carbon blocks that absorbs and converts molecular-grade contaminants such as, for example, formalin, dioxin, and ozone. The carbon filter (104) can be manufactured in accordance with the teachings of the "AIR TREATMENT FILTER AND RELATED METHOD" of U.S. Patent No. 7,316,732 issued to Tayloer, Jr., et al. The documents are incorporated by reference in their entirety.

In the particular embodiment depicted, the various filters (100, 102, 104) are nested within a filter housing (112). The filter housing (112) generally includes a carbon filter housing and a particulate filter holder. The two are generally rectangular cavities configured to house the carbon filter and the particulate filter, respectively. The carbon filter holder is slightly smaller in height and width than the particulate filter holder. Thus, the filter housing (112) is stepped with a shoulder (114) surrounding the carbon filter holder. The carbon filter (104) is first inserted into the filter housing (112). The outer dimensions of the carbon filter (104) are slightly smaller than the size of the portion of the filter housing (112) that is intended to accommodate the carbon filter (104). Thus, there is a relatively tight fit between the carbon filter (104) and the filter housing (112) which tends to push air through the carbon filter (104) rather than bypassing. The particulate filter (102) is then nested into the filter housing (112). As mentioned above, the filter housing (112) is stepped and includes a shoulder (114) for mounting the particulate filter (102) thereon. The particulate filter (102) can include a surface seal (not shown) that engages the shoulder (114) to provide a leak proof seal between the particulate filter (102) and the filter housing (112). This forces all air moving through the ATS (10) to flow through the particulate filter (102) rather than bypassing. Finally, the front filter (100) is nested into the filter housing (112) and positioned outside of the particulate filter (102). In this particular embodiment, the front filter (100) includes a frame (116) and a layer of filter media (not shown). The frame (116) is configured to be crimped directly to the particulate filter (102). For example, the frame (116) can include the fingers (117) extending inwardly and capable of engaging the particulate filter frame. In addition to the above range, the front filter (100), the particulate filter (102), and the carbon filter (104) are generally conventional. Therefore, it is not described in detail herein. While the particular embodiment depicted includes a three-stage filter arrangement, the present invention can be incorporated into ATSs having different filtration/processing arrangements.

In this particular embodiment, the ATS (10) includes untreated intake ports (106a-c) in front, allowing air to enter the system, and an exhaust port (108) behind to release the treated air back into the environment. The ATS (10) includes a blower (56) mounted behind the front front filter (100), the particulate filter (102), and the carbon filter (104). In operation, the blower (56) operates to draw untreated air from the environment through the air inlets (106a-c) into the ATS (10), actuating the air sequentially through the three filters (100, 102 and 104) to treat the air, and then Process air is released through the vent (108) to return it to the environment. The size, shape, and configuration of the air intake, exhaust, and internal airflow paths are designed to provide a miniaturized bottom area of the ATS while still providing quiet and efficient operation. The size, shape, and configuration of the air intake, exhaust, and internal flow paths may vary from application to application.

The depicted ATS (10) is merely exemplary, and the size, shape, and configuration of the ATS may vary from application to application.

C. Control system

As noted above, the present invention includes a control system (12) that controls the operation of the ATS (10) and provides a user interface for displaying information and receiving input from an operator. The main function of the control system (12) is to control the speed at which the ATS (10) is to be operated to process the air based on the measured parameters or user input, track the use of the filter, inform the operator of the operating mode, motor speed setting and filter life. And accept operator instructions. In general, the control system (12) changes the rate at which air is filtered by adjusting the speed of the blower (56). More specifically, the control system (12) controls the operation of the blower (56) in accordance with an automatic or manual control scheme, as will be described in more detail below. If desired, the control system (60) can be configured to slowly transition between multiple blower speeds. Example In the depicted embodiment, blower speed control is achieved by varying the power duty cycle supplied to the blower (56). To provide a slow transition between multiple motor speeds, the control subsystem (60) can transition from one speed to another by increasing or decreasing the duty cycle to move from the current speed to the desired speed. The timing, number and size of the steps can vary depending on the application, depending on the application.

In the depicted embodiment, the user interface is implemented as an "electroless board" display (16) that is placed toward the top of the front cover (32) and includes an integrated touch sensor. In use, the display (16) displays information and receives operator input related to the operation and maintenance of the system. For example, the control system (12) depicted in the specific embodiment displays current environmental dust levels and information regarding the remaining life of various filters. It also provides touch sensitive buttons that allow an operator to control the system. The "electroless board" display (16) includes a plurality of display elements (18) that are only visible when illuminated. The control system (12) is configured to selectively illuminate the individual display elements (18) to provide a dynamic display that changes to provide information at any given time and present available control options. In the depicted embodiment, the display (16) includes a reference display element (18a) that is illuminated to provide information about the ATS, or a monitored feature such as ambient air quality and filter life, including An input display element (18b) is incorporated with a touch sensor to allow an operator to provide input to the control system. In addition to allowing user input, the input display element (18b) can also provide information about the status of the ATS, such as, for example, the mode of operation and the blower speed.

In the depicted embodiment, the control system (12) includes an electronic component module (14) that is self-contained, that is, it includes all of the electronic components of the ATS (10), except that the AC wall power is converted to operational ATS. (10) Outside the power supply component of the required DC power. In this particular embodiment, a power supply assembly (not shown) is tethered within the base (40) of the ATS housing (110). Now According to the schematic representation of the fourth figure, the electronic component module (14) generally includes a control subsystem (60), a light emitting diode array (62), and a capacitive touch sensor array (64). ), a dust sensor assembly (66), an RFID subsystem (68), and a wireless communication subsystem (70). The control subsystem (60) includes control circuitry and firmware configured to operate the ATS (10) and coordinate collection of data from various other subsystems, including capacitive touch sensor arrays (64). ), a dust sensor (66), an RFID subsystem (68), and a wireless communication subsystem (70). The various modes of operation of the system will be described in more detail later. The control subsystem (60) also includes non-volatile memory for storing pre-programmed operational preset values as well as historical operational data such as lifetimes of filters (100, 102, and 104), usage times, counters, and possibly ATS (10) The operation is related to other variables required.

The electronic component module (14) of the specific embodiment is shown in the fifth to seventh figures. As shown in the figure, the electronic component module (14) includes a housing (148) including circuitry for controlling the subsystem (60), the RFID subsystem (68), and the wireless communication subsystem (70), as well as The circuit of the LED array (62), the capacitive touch sensor array (64), and the dust sensor assembly (66). The outer casing (148) generally includes a base (150) and a cover (152). As noted above, the array of light emitting diodes (62) is configured to provide illumination of the display elements (18). More specifically, one or more light emitting diodes (62a) are placed behind each display element (18), including an indicator display element (18a) and an input display element (18b). The light emitting diode (62a) can be selectively illuminated by the control subsystem (60) when it is suitable to display an indicator display element (18) or to enable an input display element (18) to be input. Each of the light emitting diodes (62a) may comprise a single light emitting diode or a plurality of light emitting diodes, providing various lighting options. For example, each of the light emitting diodes (62a) may include a plurality of light emitting diodes of different brightness to allow for variations in brightness of the display element (18). As another example, each of the light emitting diodes (62) can include different color light emitting diodes that can be individually or collectively illuminated to create different color illumination. In one embodiment, each LED (62) includes a red LED, a green LED, and a blue LED that can be illuminated in different combinations or at different brightnesses to provide illumination in substantially any desired color. In another example, each of the light emitting diodes (62a) may include a plurality of light emitting diodes of different brightnesses and different colors. Although the depicted embodiment includes a light emitting diode array (62) to provide illumination of the display (16), the light emitting diode array (62) can be replaced or supplemented with other types of light sources, such as, for example, OLEDs, Laser and EL light source.

In the depicted embodiment, the display (16) is an "electroless board" display in which unlit display elements (18) are not visible. In this particular embodiment, the area in which the display (16) is located appears to be a mere continuation of the ATS housing (110), and when no display element (16) is illuminated, the ATS (10) does not appear to be in use. Interface. To create the desired graphic element, each display element (16) includes a spacer (74) that shields and scatters light produced by the rear light emitting diode (62). In the depicted embodiment, the display (16) includes two spacers (74a) and (74b) each covering a plurality of light emitting diodes and providing a plurality of display elements (18) with shielding and astigmatism functions. The spacers (74a) provided are related to the indicator display elements (18a) that provide for the various filters (100, 102 and 104). The baffle (74b) is associated with an indicator display element (18a) that provides information regarding ambient air quality (eg, based on dust sensor readings), and inputs display element (18b) with power, mode of operation, and blower speed The input is related. In the depicted embodiment, each of the separators (74) is a laminate construction that generally includes a astigmatism layer and a mask layer. The astigmatism layer can be substantially any material capable of dispersing light generated by the light-emitting diode. For example, the astigmatism layer can comprise a transparent substrate covered with a semi-transparent film or other translucent coating. Alternatively, the astigmatism layer can be a transparent material having a "rough" or otherwise textured surface. In another alternative, the astigmatism layer can be a piece of translucent material. The mask layer can basically be capable of shielding light to generate desired Any material of the graphic, including various opaque and translucent materials such as inks, lacquers, films and other adhesive layers. For example, the mask layer can be an opaque film that defines an opening that is the shape of the desired pattern. It can also include a combination of different materials to provide a different visual appearance. For example, the mask layer can include an opaque region that does not require any light to pass through, a first translucent material that is desired to be transmitted by a backlight, and a second translucent material that is intended to transmit light to the front. By using different color translucent materials or translucent materials having different transparency, the first and second translucent materials can create regions that appear to be different. The mask layer can be applied to the astigmatism layer by printing, thermal bonding, adhesive, or other suitable means. In the depicted embodiment, the mask layer is placed on the outside surface of the astigmatism layer relative to the light emitting diode or other source, but it can be placed elsewhere if desired. Although a portion of a single laminate construction of the astigmatism layer and the mask layer in the particular embodiment is depicted, they can alternatively be individually separate components. For example, they can be fabricated separately and placed adjacent to one another during assembly of the display (16).

In the depicted embodiment, the light pipe array (72) has a plurality of individual conduits (72a) side by side joined together to contain light from the source and direct it to the corresponding display element. Each light pipe (72a) surrounds the light source and provides a reflective conduit to direct light from the source (62a) to the appropriate portion of the bulkhead (74a, 74b). For example, as shown in the third figure, one end of each light pipe (72a) can be configured to fit tightly to the light emitting diode (62a) and the other end can engage the partition (74b) and the size and shape thereof Designed to follow the perimeter of the associated display element (18). The inner surface of each light pipe (72a) may be reflective, diffusive or have other optical properties selected to provide the desired visual appearance of the corresponding display element (18). In the depicted embodiment, the electronic component mode (14) includes two light pipe arrays (72) - one for the filter life display and the other for the remaining display elements. In this embodiment, each light pipe array (72) is fabricated as a separate, integrated unit, thereby facilitating the electronic element Manufacturing and assembly of the module. For example, each of the light pipe arrays (72) can be injection molded and the inner surface can be coated with a trans or scattering material depending on the desired appearance.

As noted above, certain display elements (18) are input display elements (18b) that function as touch sensors to allow an operator to provide input to the control subsystem (60). The input display element (18b) can be implemented substantially using any touch sensor technology that can be incorporated into the "electroless board" display. In the depicted embodiment, the input display element (18b) is a capacitive touch sensor. In this particular embodiment, the display (16) includes a capacitive touch sensor array (64) that includes a plurality of separate capacitive film (64) sections. Each film segment is associated with a separate touch sensor. For example, each film segment can be coextensive with a display element (18b) associated with the touch sensor. For example, the capacitive film (64) can be integrated into the spacer (74a, 74b) to form a layer. Pressed to a separation level of the astigmatism layer (76) and/or the mask layer (78). Alternatively, the capacitive film (64) can be separated from the separator (74a, 74b). In the depicted embodiment, each capacitive film (64) section includes a tab (65) or other feature for attachment to the electronic component module (14), and the lower substrate (67) provides a common ground plane. . The monitoring, control, and operation of the capacitive touch sensor can be conventional in general and thus not described in detail herein. It is only noted that the control subsystem (60) can recognize the contact by sequentially reading the values from the respective discrete capacitive film segments and determining when the current reading matches a typical predetermined value for a contact.

As noted above, the electronic component module (14) of the illustrated embodiment includes a dust sensor assembly (66) that allows the control system (12) to determine the level of airborne contaminants. In this embodiment, the dust sensor assembly (66) includes a dust sensor (80), a sensor air inlet (82), a sensor conduit (81), and a sensor row. Port (86) and a pair of sensor pads (88). In this embodiment, the dust sensor assembly (66) utilizes a partial vacuum created by the blower (56) The ambient air is twitched through the dust sensor (80). After passing through the sensor (80), the air is processed and returned to the environment. As shown in the figure, the sensor vent (86) is in communication with the air flow path through the ATS (10) and is placed upstream of the filter (100, 102, 104). The sensor (80) is mounted to the electronic component module (14) and properly aligned with the sensor exhaust port (86). A sensor inlet (82) is placed within the housing of the electronics module (14) to provide a passage for ambient air to enter the sensor conduit. The sensor inlet (82) may include a filter material (not shown) selected to avoid large particles such as hair, lint, and dust cement contaminating the dust sensor (80). The filter material can be replaceable or cleanable. A sensor conduit (84) is placed between the sensor (80) and the sensor inlet (82) to provide a flow path to the sensor (80). A sensor shim (88) is located between the dust sensor and the sensor exhaust port (86) and between the dust sensor (80) and the sensor conduit (84). In operation, the blower (56) twitches air from the environment through the sensor inlet (82), the sensor conduit (84), the dust sensor (80), and the sensor vent (86). As air passes through the dust sensor (80), the level of dust in the air is measured using known techniques and devices.

Although not shown, the ATS (10) may also include an indication that the sensor can provide a reading as the presence or absence of the front cover. For example, in the depicted embodiment, the ATS (10) includes a Hall effect sensor facing the bottom of the ATS (10) near one of the magnetic sensors. When the front cover (32) is removed, the absence of the magnet changes the reading provided by the Hall effect sensor. Alternatively, a separate independent interlocking magnet (not shown) can be incorporated into the front cover (32) in proximity to the electronic component module (14) such that a Hall effect sensor, reed switch or mounted on the electronic Other magnetic field sensors on the component module (14) can be used to determine if the front cover (32) is present. Information about the status of the front cover (32) can be used by the control subsystem (60) to affect the operation of the system. For example, in one embodiment, the control subsystem (60) can be automatically turned off (56) or otherwise when the current cover (32) is removed. Change the function. As another example, when the front cover (32) is removed, the control subsystem (60) can change the parameters used to determine if a touch has occurred. This will allow the touch sensor to operate equally well regardless of whether the front cover (32) is in position. As another example, the control subsystem (60) can enter an alternate mode of operation when the front cover (32) is removed. This causes the control subsystem (60) to change the display element (18), including the input display element (18b) that is available.

The control system (12) may also include a radio frequency identification subsystem (68) configured to cooperate with corresponding radio frequency identification operations in the replaceable filter within the ATS (10). The radio frequency identification subsystem (68) is generally conventional and thus will not be described in detail herein. Simply point out that with the RFID subsystem (68), the control subsystem (60) can collect, accumulate or otherwise store the filter life, time of use, elapsed time after installation, total effective consumption (ie motor speed multiplied by use) Time), as well as other information in the RFID tag. When a filter is installed, the RFID reader can read any data already stored in the RFID tag, such as the filter life, the total amount of time the filter has been installed in any system, and the filter life. Total effective consumption. As a result, the system can provide proper tracking even if one filter moves from one ATS to another. The radio frequency identification embedded in the filter can also include a serial number that can be used to ensure the authenticity of the filter. For example, the control system (12) can store a list of available serial numbers to compare the serial numbers to, or, if it can be networked, the ability to compare the list of available serial numbers stored on the Internet. Filter usage information can be used to provide a display of the remaining filter life and provide a hint when the filter needs to be replaced. The radio frequency identification subsystem (68) can also be used to determine when a filter has been removed. This information can help control or maintain statistics about the use of the ATS (10). For example, the control subsystem (60) can be configured to shut down the blower when the particulate filter (102) and/or the carbon filter (104) are removed. As another example, the control subsystem (60) can enter a state when one or both of the filters are removed. Service mode. While in service mode, the control subsystem (60) displays information technology information and/or provides control options specific to the mode. To assist in ensuring proper alignment between the RFID reader/writer in the ATS (10) and the RFID tag in the carbon filter (104), the carbon filter (104) and the filter housing (112) can be paired such that the carbon filter (104) Can only be installed in an orientation that provides alignment. For example, the bottom of the particulate filter (104) can include a keyway (not shown) and the filter housing (112) can include a corresponding key (not shown). When the RFID reader/writer is placed in the center of a left/right direction, the key can be centered because it does not matter which surface of the filter faces inward. When the RFID reader/writer is not centered, it may be helpful to provide an asymmetric key arrangement to ensure that the desired filter surface is facing inward.

As mentioned above, the control system (12) can include a wireless communication subsystem (70) that allows the control subsystem to communicate wirelessly with other electronic devices, such as, for example, smart phones, tablets, personal computers, regional wireless routers, broadband wireless routers, and the like. Other communication devices. In the depicted embodiment, the wireless communication subsystem (70) allows the ATS (10) to receive instructions from a remote device, such as, for example, a smart phone or tablet executing a proprietary application. Device. For example, an application can be provided that allows an operator to enter an ATS command on an electronic device that wirelessly communicates to and is executed by the control subsystem (60). As another example, information collected by the ATS (10) can be communicated to an electronic device for display within the application. In conjunction with the depicted embodiments, this may include filter life information, operating mode information, motor speed information for each filter, and ambient air quality information obtained using a dust sensor. The wireless communication subsystem (70) can utilize substantially any wireless communication technology and protocol. For example, in the depicted embodiment, the wireless communication subsystem (70) may have Bluetooth and/or WiFi capabilities.

The control system (12) can be configured to implement a wide variety of control schemes. Love In this case, the control system (12) can be configured to provide a dynamic display (16) in which the display element (18) is illuminated and touched according to varying variables, such as, for example, the operating mode and the value of the monitored parameter. The control sensor is enabled. In the depicted embodiment, the control system (12) implements a control scheme having four general modes of operation, including a "smart" mode (or automatic mode) in which the control system is automated based, at least in part, on the dust sensor readings. A "manual" mode in which the operator controls the blower speed, an "acceleration" mode in which the blower (56) temporarily takes a high speed operation, and a "night" mode in which the display (16) operates in a different manner to limit Night illumination. In connection with this control scheme, the display (16) is capable of displaying various indicator display elements (18a) and input display elements (18b) (see fifth and ninth A). In the depicted embodiment, each display element (18) includes two light emitting diodes of different colors and/or different intensities. One of the two light emitting diodes is used to illuminate the display element in a "present" state (ie, a darker light emitting diode or first color, such as, for example, a softer color). This lighting state is used to make the display element (18) on the display (16) visible to the naked eye while providing a visual indication that it has not been selected or is not available. Another illuminating dipole system is used to illuminate a display element that is in an "on" state (eg, a brighter light emitting diode or a second color, such as a more vivid color). The "on" state is used to indicate that the display component is "on" or "available". The number, type, configuration, configuration, and operation of display elements (18) may vary from application to application, and most are based on control schemes implemented by the control system (12).

In the depicted embodiment, the indicator display element (18a) includes an indicator display element (200) that exhibits a pre-filter life, a set of indicator display elements (202) that exhibit a particular filter life, and a set of indicator display elements (204) The carbon filter life is presented, and a set of indicator display elements (206) present an environmental dust level (see Figure IXB). The input display element (18b) generally includes an electric Force input display component (208), a "smart" mode input display component (210), an "acceleration" mode input display component (212), a "night" mode input display component (214), and a plurality of blower speed inputs Display element (216) (see Figure IX).

In the depicted embodiment, various filter life displays (200, 202, and 204) are placed between the front cover (32) and the icon representation of the ATS housing (110). These icons help identify which filter life is associated with which filter. In the depicted embodiment, the front cover and the icon of the ATS housing are stably illuminated by a white light emitting diode operating at 50% brightness.

In the depicted embodiment, the filter life display (200) for the front filter includes an indicator display element (200) that can be illuminated in a "rendered" state when the front filter does not require maintenance, and the current filter It is "on" when maintenance is required (such as cleaning or replacement). The "presentation" state can be caused by stably lighting a green light-emitting diode. The "on" state can be provided by flashing a red light emitting diode.

In the depicted embodiment, the filter life display (202) for the particulate filter (102) includes four indicator display elements (18a), each representing a quarter of the filter life. When the filter life is shown as on, all four display elements (18a) are illuminated. The number of elements (18a) illuminated in the "on" state represents the remaining filter life. The remaining components (18a) are illuminated in a "present" state to provide a visual reminder of the filter life in four equal representations. The number of paragraphs can vary from application to application depending on the application. For example, additional fineness can be provided by increasing the number of indicator display elements (18a) associated with the filter life display (202). In the depicted embodiment, the filter life for the particulate filter is shown (202) with a colored light emitting diode to assist in presenting the filter life as follows:

75-100% life - all four paragraphs with 100% brightness green illumination

50-75% life - the bottom three paragraphs are 100% bright green, and the top paragraph is 50% white illuminated

25-50% life - bottom paragraph with 100% brightness yellow illuminated, top three paragraphs with 50% white illumination

1-10% life - the bottom paragraph is 100% bright red, the top three paragraphs are 50% white illuminated

0% life - bottom paragraph with 100% brightness red flashing, top three paragraphs with 50% white illumination

In the depicted embodiment, the filter life display (204) for the carbon filter (104) is substantially identical to the filter life display (202) for the particulate filter (120), including four display elements (18a). It can be illuminated in the "present" or "on" state using the same method described above.

In the depicted embodiment, the dust level display (206) includes a plurality of individually separated indicator display elements (18a) that can be illuminated in a "present" or "on" state. When the dust level display (206) is displayed, the number of indication display elements (18a) illuminated in the "on" state represents the measured dust level, and the other indicator display elements (18a) are illuminated in "presentation" status. This allows the operator to know more about the dust level by comparing the ratio of the "open" paragraph to the total number of paragraphs. In the depicted embodiment, the dust level segments are divided into three groups, with a single set of light emitting diodes associated with each of the three sets of segments. Thus, the dust concentration display (206) of the depicted embodiment has 15 paragraphs, but only six different settings (i.e., 0 paragraphs, 3 paragraphs, 6 paragraphs, 9 paragraphs, 12 paragraphs, and 15 paragraphs). In the depicted embodiment, the dust concentration is displayed (206) with colored light-emitting diodes to assist in identifying as follows:

Level 1 - The first paragraph is illuminated with 100% brightness green, and the remaining paragraphs are 50% brightness white

Level 2 - the first two paragraphs are illuminated with 100% brightness yellow, and the remaining paragraphs are 50% brightness white

Level 3 - The first three paragraphs are illuminated with 100% brightness yellow, and the remaining paragraphs are 50% brightness white

Level 4 - the first four paragraphs are illuminated with 100% brightness red, and the remaining paragraphs are 50% brightness white

Level 5 - All five paragraphs are illuminated with 100% brightness red

In this embodiment, the blower speed display element (18b) performs a dual function of displaying the current blower speed and receiving the touch sensor input to allow the operator to manually set the blower speed. As shown by the dust level display, the blower speed display includes a plurality of separate display elements (18) having two light emitting diodes that are selectively illuminated to indicate a "present" state or an "on" state. Unlike the dust level display, the blower speed display is also a touch sensor array that can be used by an operator to manually select a blower speed. When the blower speed is displayed, the number of blower speed input display elements illuminated in the "on" state is selected to represent the blower speed, and the other blower speed input display elements are illuminated in the "present" state so that the operator You can see the available blower speed options and compare the ratio of the "open" paragraph to the "present" paragraph to see the current blower speed. In the depicted embodiment, the "present" state can be caused by stably illuminating a white light emitting diode with 50% brightness. The "on" state can be provided by stably illuminating a blue light emitting diode with 100% brightness. To provide a touch sensor, each blower speed display element (18b) includes an associated capacitive film section. As described above, the control subsystem (60) monitors the capacitive film segments to determine when a touch occurs. When a touch occurs, the control subsystem (60) can adjust the blower speed to match the selected setting.

In the depicted embodiment, the power input display element (208) is illuminated with 100% brightness red when in the "present" state and illuminated with 100% brightness white when in the "on" state. The "Smart" mode input display element (210) is 50% when in the "present" state. Brightness is illuminated in white and is illuminated in 100% brightness when in the "on" state. When in the "present" state, the "acceleration" mode input display element (212) is illuminated with 50% brightness white, and is illuminated with 100% brightness blue when in the "on" state. When in the "present" state, the "night" mode input display component (214) is illuminated with 50% brightness white, and is illuminated with 50% brightness red when in the "on" state.

As described above, the control system (12) of the specific embodiment implements a control scheme having four different modes of operation: "smart" mode (or automatic mode), "manual" mode, "acceleration" mode, and "nighttime". mode. This control scheme will be described with reference to the thirteenth diagram. During the "smart" mode of operation, the control subsystem (60) evaluates the dust sensor readings and determines a blower speed based on these readings. This allows the ATS (10) to be adapted to varying levels of airborne dust. In this mode, the operator has the option to enter acceleration mode, night mode, manual mode or turn off the ATS power. Accordingly, the acceleration mode input display element, the night mode input display element, the various blower speed input display elements, and the power input display element are illuminated. The acceleration mode input display element and the night mode input display element are illuminated in the "presentation" state. The smart mode input display component and the power input display component are illuminated in an "on" state. When the system has been operated in the smart mode, if the smart mode input display element is touched, the system will switch to the manual operation mode. The blower speed input display element is illuminated to show the current blower speed and the manual adjustment options available in accordance with the illumination method proposed above. Furthermore, in the smart mode, the dust level indicates that the display element is illuminated to display an instant dust level that is consistent with the illumination method proposed above. In the smart mode, each time the user interacts with the ATS (10), the filter life display is illuminated for a specific period of time. For example, each time an operator interacts with a touch sensor in the display (16), the control subsystem (60) can illuminate a period of 15 seconds for which the filter life is displayed. In addition, whenever you want a filter Need to pay attention (for example, any filter needs to be cleaned or replaced), the filter life display can be illuminated.

When the operator touches a blower speed input display element (18b), the control subsystem enters manual mode (or direct mode). Once in the manual mode, the control subsystem (60) operates the blower (56) at the speed selected by the operator. In this mode, the operator has the option to enter acceleration mode, night mode, smart mode, adjust blower speed or turn off ATS power. Accordingly, the acceleration mode input display element, the night mode input display element, the smart mode input display element, the various blower speed input display elements, and the power input display element are illuminated. The smart mode input display element, the acceleration mode input display element, and the night mode input display element are illuminated in a "presentation" state. The power input display element is illuminated in an "on" state. The blower speed input display element is illuminated to show the current blower speed and the manual adjustment options available in accordance with the illumination method proposed above. In addition, the dust level indicates that the display element is illuminated to display an instant dust level that conforms to the illumination methodology presented above. In this mode, each time the user interacts with the ATS (10), the filter life display is illuminated for a specific period of time. For example, each time an operator interacts with a touch sensor in the display (16), the control subsystem (60) can illuminate a period of 15 seconds for which the filter life is displayed. In addition, the filter life display can be illuminated whenever the filter needs attention (eg, any filter needs to be cleaned or replaced).

When the operator touches the acceleration mode input display element, the acceleration mode is entered. Once in the acceleration mode, the control subsystem (60) operates the blower (56) for a predetermined period of time (e.g., 30 minutes) using a high speed setting (or other predetermined speed setting) and then automatically returns to the previous mode of operation. The acceleration mode can be interrupted by a touch of a button, wherein the system can transition away from the acceleration mode before the preset time period expires. In this mode, the operator has the following options: touch the smart mode The display element is input to enter the smart mode, the touch-blower speed input display element is used to adjust the blower speed, and the manual mode or the touch power input display element is turned on to turn off the ATS power supply and the like. Further, the operator has a touch acceleration mode input display element to cause the system to immediately return to the previously set option. Accordingly, the acceleration mode input display element, the smart mode input display element, the various blower speed input display elements, and the power input display element are illuminated. The acceleration mode input display element and the power input display element are illuminated in an "on" state, and the smart mode input display element is illuminated in a "presentation" state. The blower speed input display element is illuminated to show the current blower speed and the manual adjustment options available in accordance with the illumination method proposed above. In addition, the dust level indicates that the display element is illuminated to display an instant dust level that conforms to the illumination methodology presented above. In this mode, each time the user interacts with the ATS (10), the filter life display is illuminated for a specific period of time. For example, each time an operator interacts with a touch sensor in the display (16), the control subsystem (60) can illuminate a period of 15 seconds for which the filter life is displayed. In addition, the filter life display can be illuminated whenever a filter requires attention.

When the operator touches the night mode input display element, it enters the night mode. Upon entering the night mode, the control subsystem (60) continues to operate the ATS (10) in the same mode, but the displayed content is reduced to minimize light emission. In this mode, the operator has the option of canceling the night mode by touching the night input display element (ie, re-enabling the display in accordance with the current operation mode), or turning off the ATS or the like by the touch power input display element. In night mode, only the night mode input display elements and power input display elements are illuminated, and both are illuminated in an "on" state. In an alternate embodiment, when the operator comes close to the display (16), the control subsystem (60) can be configured to re-enable the display (16) (all or part). For example, the control subsystem (60) can use a capacitive touch sensor array (64) to sense operator lean Nearly, it is used as a trigger to illuminate all of the input display elements (18b) so that the operator has an entire set of controls. If the operator does not enter an instruction within a certain time period (e.g., 15 seconds) after display (16) has been re-enabled, the control subsystem (60) may cause display (16) to return to night mode.

If the ATS (10) is plugged in but not powered, the control subsystem (60) illuminates the power input display element in a "present" state. This allows the operator to see the power control components. Once the power button is touched, the control subsystem (60) can start the system in either smart mode or manual mode. When starting in the manual mode, the control subsystem (60) reads the dust sensor readings, determines the appropriate blower speed based on the dust sensor readings, and then loads the blower at the determined speed. All of these steps are automated and do not require operator input. When starting in manual mode, the control subsystem (60) does not start the blower (56) until it is instructed to do so by operator input, for example, by the operator touching one of the blower speed input display elements (18b) ).

The control schemes described above are merely exemplary. The control system (12) can implement various alternative control schemes. For example, Figure 14 depicts an alternative control scheme. Except for the portions described herein, the alternative control scheme is substantially identical to the control scheme described above. To implement this control scheme, the display may include an additional mode control button associated with the "manual" mode (labeled "user" in Figure 14). With this control scheme, the operator needs to use the mode control buttons to switch between different modes of operation. For example, the operator needs to touch the "user" mode input display element to enter the manual operation mode (instead of simply touching a blower speed input display element). Once in manual mode, the operator can control the blower speed by touching the desired blower speed input display element. In another example of the control scheme, the operator can only leave the acceleration mode by inputting the display element by the touch acceleration mode or allowing the preset time to pass. Similarly, the operator can only leave the night mode by inputting the display element by touching the night mode.

The fifteenth figure depicts another alternative control scheme. In this particular embodiment, the control scheme is substantially identical to the first control scheme described above except for the portions described herein. To implement this control scheme, the display includes an additional mode control button associated with the "option" mode (labeled "option" in Figure 15). When the system is powered up, it starts in "smart" mode and the blower speed is automatically set based on the input from the dust sensor. To provide additional control options, you have to touch the "Select" mode button. In the "Wisdom" mode, the power input display component is illuminated in the "on" state, the smart mode input display component is illuminated in the "on" state, and the option mode input display component is illuminated in the "presentation" state, and the dust level is The display is illuminated. The acceleration mode input display element, the night mode input display element, and the blower speed display are turned off. In the smart mode, the operator can touch the power input display element to turn off the system power, or the touch option mode input display element to be converted into the option mode.

Once in the "Smart" mode, the power input display component is illuminated in the "on" state, the smart mode input display component is illuminated in the "on" state, and the option mode input display component is illuminated in the "on" state, the dust level. The display and blower speed display are illuminated. In addition, the acceleration mode input display element and the night mode input display element are illuminated in a "presentation" state. In the option mode, the operator can touch the power input display component to refer to the system power, the touch smart input display component to return to the smart mode, the touch option mode input display component to return to the smart mode, and the touch acceleration mode input display component to enter In the acceleration mode, the touch night mode inputs the display element to enter the night mode, or touches a blower speed input display element to select a blower speed and enter the manual mode. If no button is touched during a certain period of time (for example, 60 seconds), the system can automatically return to the smart mode.

Once in the "manual" mode, the power input display element is illuminated "on" In the "on" state, the option mode input display element is illuminated in the "presentation" state, the dust level display is illuminated and the blower speed display is illuminated. In addition, the smart mode input display element, the accelerated input display element, and the night input display element are turned off. In the manual mode, the operator can touch the power input display component to turn off the system power, the touch option mode inputs the display component to enter a "manual option" mode, or touches a blower speed input display component to select a blower speed.

Although the system remains in manual mode, it will continue to operate the blower at the operator's selected speed.

Once in the "Manual Option" mode, the power input display component and the option input display component are illuminated in the "on" state, and the dust level display and the blower speed display are illuminated. In addition, the smart mode input display element, the acceleration mode input display element, and the night mode input display element are illuminated in a "presentation" state. In the manual mode, the operator can touch the power input display component to turn off the system power, touch the smart input display component to return to the smart mode, the touch option mode input display component to return to the manual mode, and the touch acceleration mode input display component to Entering the acceleration mode, the touch night mode inputs the display element to enter the night mode, or touches a blower speed input display element to select a blower speed and return to the manual mode. If no button is touched during a certain period of time (for example, 60 seconds), the system can automatically return to the smart mode. If no button is touched during a certain period of time (for example, 60 seconds), the system can automatically return to manual mode.

Once in the "Acceleration" mode, the control subsystem operates the blower for a period of time (eg, 30 seconds) at the highest speed setting (or some other predetermined speed setting) and then automatically returns to the previous operating mode. The acceleration mode can also be interrupted by a touch of a button, in which case the system can transition away from the acceleration mode before the preset time period expires. The acceleration mode input display element and the power input display element are illuminated in an "on" state. The blower speed display and dust level display are also illuminated. In addition, the smart mode input display element, the option input display element, and the night input display element are turned off. In this mode, the operator has the following options: touch acceleration mode input display element to return to the previous operation mode, or touch power input display element to turn off the ATS power.

Once in the "night" mode, the control subsystem continues to operate the ATS in the same mode of operation, but the displayed content is reduced to minimize light emission. In the night mode, the night mode input display element is illuminated in the "presentation" state, and the power input display element is illuminated in the "on" state. The remaining display elements are off. In this mode, the operator has the option of deactivating the night mode by touching the display element at night (ie, re-enabling the display corresponding to the current operation mode), or turning off the display element by the touch power input. ATS.

D. Front cover

As mentioned above, the ATS (10) includes a detachable front cover (32) that encloses the ATS (10) front cover filter (100, 102 and 104) as well as an electronic component module (14) and a blower (56). The front cover (32) of the depicted embodiment defines a central air inlet (106a) and is offset from the ATS housing (110) such that they collectively define a side air inlet (106b-c). An air inlet correction member (98) can be nested into the central air inlet (106a). In the depicted embodiment, the front cover (32) is convex, creating a relatively large head space between the rear surface of the front cover (32) and the installed filter. This allows air to enter the ATS (10) more freely through the central air inlet (106a).

In this embodiment, the front cover (32) also forms the interface of the "electroless board" display (16). As such, the front cover (32) of this embodiment covers the LED array (62), the light pipe array (72), and the spacers (74a) and (74b), at least in the electronic component module (14). The area is translucent (for example, not completely transparent or completely opaque with respect to visible light). The front cover (32) may be made of a semi-transparent polymer (for example, a molded thermoplastic rubber) having a paint coating or a film coating For the desired opacity. In one embodiment, the front cover (32) is covered by an in-mold film process. To promote proper appearance of the "electroless board" display, it may be necessary to carefully control the paint or film coating applied to the front cover (32). Alternatively, the front cover (32) may be made of a semi-transparent material such as, for example, a molded translucent thermoplastic rubber.

In the depicted embodiment, the front cover (32) is configured to allow for one hand removal and installation. The front cover (32) includes a mechanical attachment point on top of it and a pair of magnetic attachment points on the bottom. In the depicted embodiment, the mechanical attachment point is fastened to the electronic component module (14). This helps to ensure proper alignment between the front cover (32) and the hidden display (16) components, which can assist in ensuring proper appearance and operation of the "electroless plate" display. In the depicted embodiment, although the mechanical attachment point is secured to the electronic component module (14), other configurations may be deducted in alternative embodiments.

Referring again to Figures 19A and 19B, the mechanical attachment point of the illustrated embodiment includes a mouthpiece (36) extending from the front cover (32) and configured to engage the electronic component module (14). In the depicted embodiment, the mouthpiece (36) extends substantially the entire width of the electronic component module (14) except that it may include a spacing (37) (see Figure 2) and a dust sensor inlet ( 82) Alignment. The mouthpiece (36) of this embodiment is oriented at an angle that allows the mouthpiece (36) to be snapped onto the electronic component module (14) when the front cover (32) is placed in position. This allows the front cover (32) to be uncoupled from the ATS housing (110) by sliding it up relative to the ATS housing (110). This upward sliding action not only unwinds the mouthpiece (36) from the electronic component module (14), but also simultaneously uncouples the magnet (90) from the attachment tab (92) in the ATS housing (110) (see below) Discussion), thus facilitating removal. The size, shape and configuration of the mouthpiece (36) may vary from application to application. In an alternative embodiment, the mouthpiece can be substantially replaced by any other male or female structure that can be engaged with the electronic component module (14).

In this particular embodiment, the front cover (32) includes two magnetic attachment point locations that face the opposite sides of the bottom of the front cover (32). Each magnetic attachment point includes a magnet (90) carried by the front cover (32) and a magnetic attachment tab (92) for mounting the ATS housing (see Figures 20A and 20B). The magnet (90) may be a dish-shaped rare earth magnet that is mounted in a corresponding receptacle (94) projecting from behind the front cover (32). The attachment piece (92) can be sized and shaped such that the front cover (32) slides up a sufficient distance to allow the magnet (90) to substantially separate from the connector (36) when it exits the electronic component module (14). The tab (92) is unlocked. The size, shape and configuration of the magnets and attachment tabs may vary depending on the application. For example, a stronger magnet or a more magnetic attachment point can be used to increase the force required to remove the front cover (32).

The front cover (32) can be removed and installed in a variety of ways when in use. An option to remove the front cover (32) is shown in Figure 17A. With this option, the front cover (32) slides up a sufficient distance relative to the ATS housing (110) to allow the mouthpiece (36) to exit the electronics module (14), and then the top of the front cover (32) is tilted away from the ATS housing ( 110) to overcome any residual magnetic attraction at the magnetic attachment points. The front cover can basically be installed using the opposite procedure. Figure 17B shows another option for removing the filter. With this option, the operator pulls down and pulls the bottom of the front cover (32) away from the ATS housing (110) until the magnet (90) is unwound from the attachment tab. The operator then lifts the front cover (32) a sufficient distance to allow the mouthpiece (36) to exit the electronic component module (14). The front cover (32) can be unscrewed by pulling the top end of the front cover (32) over the electronic component module (14) and then rotating the bottom of the front cover (32) toward the ATS housing (110) until the magnets (90) are buckled The piece is installed.

The front cover (32) may include an interlocking magnet (not shown) that allows the control subsystem (60) to recognize when the front cover (32) is installed and when it is removed. The snap magnet can be placed facing the top of the front cover (32) where it can be incorporated into the electronic component module (14) by a Hall effect or His magnetic field sensor sensed. As an alternative to using a separate snap magnet, the ATS (10) may include a Hall effect sensor (or other magnetic field sensor) that is placed to allow it to be attached to the front cover (32). The magnet (90) to the ATS housing (110) identifies whether the front cover is still or not.

If desired, the electronic component module (14) can include a light emitting diode or other light source that can be used to provide illumination through the central air inlet opening (106a) and/or in the front cover (32). The side is seen by the naked eye. This illumination can be provided to emphasize illumination or can have a functional purpose. For example, when the ATS (10) is functioning properly and requires no maintenance, the control system (12) can provide blue illumination or no illumination, and it can provide red illumination when an operator intervention is required. This need occurs when a filter needs to be replaced or cleaned, or when there is a system error. The red illumination can flash when there is a specific emergency.

As noted above, the front cover (32) incorporates an appropriate level of opacity to create an "electroless board" display (16). As an alternative, the "electroless board" display can be placed under the front cover (32) by a transparent member, such as, for example, a separate panel placed over the electronic component module (14). In this embodiment, the front cover (32) may be transparent or sufficiently translucent to allow the hidden "electroless panel" display to be seen through the front cover (32).

E. Mobility characteristics

In the depicted embodiment, the ATS (10) can be configured to interface with one of a plurality of detachable bases (40). In the depicted embodiment, the bases (40, 40' and 40") are secured to the ATS housing (110) using screws or other fasteners. The number and location of the components may vary depending on the application. As an alternative or in addition to the knot, the ATS housing (110) and the base (40, 40' and 40") may be provided with a snap feature that allows the desired base to be snapped into the ATS (10).

Different pedestals (40) may be provided in different configurations for receiving power lines (42) and/or Different configurations are used to support the ATS (10). The twenty-first and twenty-second figures show that an ATS (10) has three alternative pedestals (40, 40' and 40"). In general, the pedestal (40) has a bobbin (44). For manually winding the power line (42'), and a plurality of casters (46); the base (40') has a bobbin (44') for manually winding the power line (42'), and a plurality of Casters (46'); and the base (40") includes a wire return assembly (45) having an automatic tightening reel (not shown), as well as a fixed stand (46") and a roller (47" )The combination. Although the illustration shows that a particular embodiment of a spool of wire extends laterally across a portion of the ATS housing (110), the term "winding shaft" is intended to include any individual individual feature or combination of features, presented as a power line (42). A construction that can be wound thereon.

In the depicted embodiment, the ATS (10) can also include a handle (48) placed on the back side of the top of the ATS housing (110). The handle (48) of this particular embodiment extends substantially the entire width of the ATS (10) to allow the ATS (10) to be grasped centrally by a single hand or relatively grasped by both hands. In this particular embodiment, the handle (48) can include a relatively deep central pocket depth sufficient to receive an operator's finger up to about two knuckles, and a relatively shallow side pocket depth sufficient to accommodate an operation The finger of the person is up to about the first knuckle. The handle (48) may be a one-piece element that is secured to the ATS housing (110), for example, by a knot, or it may be integrally formed with other portions of the ATS housing (110).

With regard to the base (40), the handle (48) can be used to lift the ATS (10) when moving the ATS (10) from one location to another. Regarding the base (40'), when the ATS is to be slid from one place to the other with the casters (46'), the handle can be used to grasp the ATS. With respect to the base (40"), the handle (48") can be used to tilt the ATS (10) forward onto the roller (47") and slide the ATS (10) from one location to another.

F. Filter holder assembly

As described above, the ATS (10) includes a front filter (100) and a particulate filter (102). And a carbon filter (104) is detachably fitted into a filter housing (112). The system includes a filter holder assembly (50) to facilitate quick and robust filter installation and removal. In the depicted embodiment, the filter holder assembly (50) includes a cleat (52) and a frame into which the pair of clips (54) are integrated into the particulate filter (102), and a locking projection (126) Integrated into the ATS housing (110). Because the front filter is fixed to the particulate filter (102) and the particulate filter (102) covers the carbon filter (104), the filter holder assembly (50) effectively secures all three filters (100, 102, 104). In the depicted embodiment, the clips (54) are configured such that when they are closed, the particulate filter (102) is pulled tightly toward the filter housing (112). This facilitates compression of one side seal (118) on the particulate filter (102) to the shoulder (114) to promote a hermetic seal.

Referring now to Figure 29B, the cleat (52) is placed in the center of the bottom of the frame of the particulate filter (102). The cleat (52) of this embodiment is integrally molded with the frame of the particulate filter (102), but it can alternatively be separately formed and attached to the frame. The buckle (52) of the illustrated embodiment has a quarter-circular cross-section that facilitates the mounting and removal of a corresponding void (120) from within the filter housing (112). The size, shape and configuration of the cleats (52) and voids (120) may vary depending on the application. For example, the cleats (52) and the voids (120) may be positioned oppositely, the cleats extending from the filter housing (122) and the voids being defined in the particulate filter (102).

Alternatively, as best shown in Figures 29A and 29B, the cleats (54) are rotatably mounted to opposite sides of the frame of the particulate filter (102). Each cleat (54) includes a handle (122) and a hook (124). The handle (122) is configured to provide a structure that can be used by a user to rotate the clips (54). The hook (124) is configured to engage the locking projection (126) when the buckle (54) is turned into the closed position. The hook (124) and the locking projection (126) are configured such that when the clip (54) is near the closed position there is a small distance between the two. This results in a press fit that assists in securing the clip (54) In the closed position. Further action to the closed position causes the hook (124) to bend, resisting further movement toward the closed position. When the clip (54) continues to the closed position, the hook (124) leaves the intersection area and begins to return to its original unbent state. This pushes the remaining path of the buckle (54) into the closed position. In the depicted embodiment, the position and configuration of the hook (124) relative to the position of the pivot is selected such that the clip (54) provides a cam-like function that will be applied when the clip (54) is closed. The filter (102) is pulled into the filter housing (112). The operation of the clip (54) is shown in Figures 30A through 30D. In the thirty-third diagram, the buckle (54) is shown in the open position. In this position, the hook (124) is unwound from the locking projection (126). Figure 30B shows the clip (54) in a partially closed position. It can be seen that the hook (124) has been moved into engagement with the locking projection (126). Used in this position, the particulate filter (102) has been partially pulled into the filter housing (112), as can be seen by comparison with the reference line R. Figure 30C shows the clip (54) moving further to the closed position. In this view, the hook (124) has engaged the locking projection (126) and has begun to flex outwardly away from the locking projection (126) due to the intersection between the two. It can be seen that the particulate filter (102) has been further pulled into the filter housing (112). In the thirty-third diagram, the buckle (54) is shown in the closed position. In this position, the hook (124) has moved past the intersection and is fully engaged with the locking projection (126). The particulate filter (102) has been fully pulled into the filter housing (112).

The removal of the particulate filter (102) is described in connection with the twenty-eighth through twenty-eighth D diagrams. In the first illustration, the front cover (32) and the front filter (100) are removed to provide access to the particulate filter (102) (see Figure 28A). In the particular embodiment depicted, it is not necessary to remove the front filter (100) from the particulate filter (102). In the next illustration, each of the fasteners (54) has been rotated from the closed position to the open position (see Figure 28B). The hook (124) is thus unwound from the locking projection (126) in the filter housing (112). The next illustration shows that the top of the particle filter (102) is tilted away from the filter housing (112) (see Figure 28C). The final illustration shows that the filter (102) is lifted off. The filter housing (112) disengages the cleat (52) from the void (120) (see Figure 28D). The particulate filter (102) can be installed substantially using the reverse procedure.

The design and configuration of the clips may vary depending on the application. Alternative clips (54') and (54") are shown in Figures 31A through D and 32#A through D. In these alternative embodiments, the filter holder assembly further includes a lock Pin (128', 128") with its securing clips (54', 54") in the closed position. Locking pins (128', 128") project from the particulate filter (102), but alternatively if necessary Can protrude from the filter housing (112). The alternative clip (54') includes a tooth (130') that projects from the outer edge of the clip (54'). The teeth (130') are configured to engage a corresponding recess (132') in the locking pin (128') when the buckle (54') is in the closed position. Together, the teeth (130') and the locking pin (128') are crimped to lock the buckle (54') in the closed position. Referring to Figures 31A through D, the operation of the fasteners (54') is shown. In the thirty-first A diagram, the buckle (54') is shown in the open position. In this position, the hook (124') is unwound from the locking projection (126'). Figure 30B shows the clip (54) in a partially closed position. It can be seen that the hook (124') has been moved into engagement with the locking projection (126'). In this position, the particulate filter (102) has been partially pulled into the filter housing (112), as can be seen by comparison with the reference line R. In this view, the hook (124') has further engaged the locking projection (126') and further pulls the filter (102) into the filter housing (112). In the thirty-first D diagram, the buckle (54') is shown in the closed position. In this position, the teeth (130') have become seated within the recess (132') and the particulate filter (102) has been fully pulled into the filter housing (112). The interaction between the teeth (130') and the locking pin (128') helps the securing clip (54') to be in the closed position.

The alternative clip (54") is similar to the clip (54'). In this particular embodiment, the clip (54") includes a series of contours that interact with the locking pin (128") to control the clip (54). ") action and touch. More specifically, the clip (54") includes a stop (134") and a (136") is configured to The buckle (54") is engaged with the locking pin (128") when in the open or closed position. The stop (134") is configured to engage the locking pin (128" when the buckle (54") is in the fully open position. The stop (134") helps limit the buckle (54") Range of motion. The seat (136") is configured to interlock with the locking pin (128" when the buckle (54") is in the fully closed position. The leading edge of the seat (136" can be raised such that when the buckle (54") is closed or opened, a snap-fit interaction is created. The operation of the fasteners (54") will now be described with reference to Figures 32A through D. In the thirty-second A diagram, the buckles (54") are shown in the open position. In this position, the hook (124") is unwound from the locking projection (126") and the stop (134") is disengaged from the locking pin (128"). Figure 32B shows that the clip (54") is in a partially closed position. The hook (124") has been moved into engagement with the locking projection (126"). In this position, the particulate filter (102) has been partially Pulling into the filter housing (112) can be seen by comparison with the reference line R. The thirty-second C-picture shows that the clip (54") is moved further to the closed position. In this view, the hook (124") has further engaged the locking projection (126") and pulls the filter (102) further into the filter housing (112). Moreover, the leading edge of the seat (136") has begun to engage the locking pin (128"). In the thirty-second D-picture, the clip (54") is shown in the closed position. In this position, the locking pin (128") and the seat (136") are fully engaged and the particulate filter (102) has been fully pulled in. Within the filter housing (112), the relationship between the locking pin (128") and the seat (136") helps the securing clip (54') to be in the closed position.

G. Alternative embodiments

The invention can be practiced in various specific embodiments. For example, an alternate embodiment is shown in the thirty-third A to fifty-three D diagram. In addition to the following description or the content shown in the accompanying drawings, this alternative embodiment is generally identical to the specific embodiment shown in the first to the twentieth. To facilitate the disclosure of the present invention, this alternative embodiment will use the same reference numerals as the reference numerals used in connection with ATS (10). To be described, except that the number "4" is added to the front. For example, an alternate ATS is specified with reference numeral (410) (similar to ATS (10)), and the ATS outer shell of the alternate ATS is designated by reference numeral (4110) (similar to the ATS housing (110)).

Referring now to Figures 33A, 33B and 34, the ATS (410) generally includes a housing assembly that houses a control system (412), a blower (456), and a front filter (4100). ), a particulate filter (4102), and an activated carbon filter (4104). The ATS (410) includes an untreated air inlet (4106a-c) at the front end through which untreated air is drawn into the system, and an air vent (4108) at the rear end through which the treated air passes. Return to the environment (see Figure 44). In operation, the control system (412) operates the blower (456) to draw untreated air through the intake ports (4106a-c) into the ATS (10), moving the untreated air sequentially through the three filters (4100, 4102). And 4104), and then untreated air is released through the exhaust port (4108). The size, shape, and configuration of the air intake, exhaust, and internal flow paths may vary from application to application.

Referring again to the thirty-fourth diagram, the outer casing assembly generally includes a main outer casing (4110), a filter outer casing (4112), and a top outer casing (4113). The main housing (4110) primarily forms the rear, side and bottom of the ATS (410). As with the ATS (10), a filter housing (4112) is attached to the main housing (4110) to enclose the front of the ATS (410) and provide a seat for the particulate filter (4102) and the carbon filter (4104). Or as best shown in the forty-ninth diagram, the top outer casing (4113) is attached to the rear side of the filter housing (4112), such as by screws (not shown). The top housing (4113) includes an integrated handle (448). In this particular embodiment, the handle (448) includes a central section that can be grasped by a single hand and a pair of side sections that can be grasped by both hands. In the depicted embodiment, the main housing (4110) includes a cord reel (444) (or bobbin) for manually winding a power cord (not shown) (see Figure 33B). In this particular embodiment, the bobbin (444) includes a pair of fingers (445) spaced apart at The opposite side of the power line input (447). The size, shape and configuration of the fingers (445) may vary, for example, depending on the characteristics of the power cord. As shown in the figures, the cord reel (444) can be placed in a recess in the main housing (4110) such that it does not protrude and thus does not increase the profile of the ATS (4110).

The ATS (410) includes a detachable front cover (432) that encloses the ATS (410) front cover display (416) and filters (4100, 4102 and 4104). As can be seen in the various figures, such as for example thirty-three a, forty-four and forty-six, the front cover (432) defines a central air inlet (4106a) and is spaced from the filter housing (4112). Separately, the front cover (432) and the filter housing (4112) are combined to define side air inlets (410b-c). The front cover (432) is constructed from an opaque plastic material, for example, by injection molding. The front cover (432) can alternatively be made from a wide variety of materials. In this particular embodiment, the front cover (432) includes a window (433) that covers the display (416). The window (433) is nested into a corresponding opening (435) defined in the front cover (432). To hide unlit display elements, the window (433) of this particular embodiment is translucent at least in one or more regions that cover the display elements (418). The window (433) can be made of a semi-transparent polymer (e.g., a molded thermoplastic rubber) having a paint coating or film coating to provide the desired opacity. In one embodiment, the window (433) is coated by an in-mold film process. To facilitate proper presentation of "electroless board" displays, it may be necessary to carefully control the paint or film coating applied to the window (433). Alternatively, the window (433) may be made of a semi-transparent material such as, for example, a molded translucent thermoplastic rubber.

In the depicted embodiment, the front cover (432) is configured to allow for one-handed removal and installation. The front cover (432) includes a mechanical attachment point on top of it and a pair of magnetic attachment points on the bottom. Referring now to the forty-fifth A, forty-fifth, and forty-sixth drawings, the mechanical attachment point of the illustrated embodiment includes a cleat (or mouthpiece) that extends from the front cover (432) and is woven by Configuration in sets The seat (437) in the electronic component module (414) is inserted into the structure surrounding the electronic device module (414). The cleats (436) may be fabricated separately and attached to the front cover (432) (see Figure 46) or may be integrally formed with the front cover (432) (not shown). The stop (436) of this particular embodiment is oriented at an angle that allows the cleat (436) to remain in the seat (437) when the front cover (32) is closed. The front cover (432) is thus allowed to be unwound from the ATS housing (4110) by sliding upward relative to the ATS housing (4110). This skidding action not only disengages the cleat (436) from the seat (437), but also simultaneously uncouples the magnet (490) from the attachment tab (492) in the ATS housing (4110) (as discussed below), This promotes removal. The size, shape and configuration of the cleats (436) may vary from application to application. In an alternative embodiment, the cleat (436) can be substantially replaced by any male or female configuration that can engage the seat (437) or other similar configuration in or around the electronic component module (414).

The front cover (432) of this particular embodiment includes two magnetic attachment point locations that face the opposite sides of the bottom of the front cover (432). Each magnetic attachment point includes a magnet (490) carried by the front cover (432) and a magnetic attachment tab (492) mounting the ATS housing (4110) (see FIG. 48). The magnet (490) may be a dish-shaped rare earth magnet mounted in a corresponding receptacle (494) projecting from behind the front cover (432). In this particular embodiment, the attachment tab (492) is configured to perform two functions - (i) providing a magnetically attracting configuration for the magnet (490) and (ii) rotatably supporting a roller (447). In this particular embodiment, each attachment tab (492) is generally L-shaped with a first leg (493) positioned to receive a magnet (490) and a second stand (495) ) rotatably supports the drum (447). The first leg (493) and the second leg (495) are generally planar, but may include ridges or other contours to enhance strength or to mate with adjacent elements of the ATS (410). The first leg (493) includes a pair of mounting tabs (491) extending rearwardly and allowing the attachment tab (492) to be attached to the housing (4110), for example, by screws (not shown). The second leg defines a circular opening (497) configured to rotatably receive the rotation of the drum (447) Axis (or pivot). In use, the two attachment tabs (492) intercept the end of the pivot or shaft of the drum (447). In this particular embodiment, the attachment tab (492) is stamped from sheet material and configured to facilitate left or right hand so that the same attachment tab (492) can be rotated by simply rotating the attachment tab 180 degrees is used on the opposite side of the ATS (410). For example, the mounting tabs (491) can be centered vertically and each tab (491) is placed at the same distance from the corresponding end of the first leg (493). Moreover, the circular opening (497) can be vertically positioned on the second leg (495).

In this particular embodiment, the control system (412) includes a capacitive sensor that allows the system to recognize when the front cover (432) is installed and when it is removed (discussed in more detail below). This eliminates the need for any interlocking magnets or magnetic field sensors used to determine the presence of the front cover, as discussed above with respect to ATS (10).

As described above, the ATS (10) includes a front filter (4100), a particulate filter (4102), and a carbon filter (4104). As with the ATS (10), the filters are secured within the ATS (410) by a filter holder assembly (450) incorporated into the particulate filter (4102). More specifically, the filters are mounted by a filter holder that fits a carbon filter (4104) into the filter housing (4112), and a filter holder that fits the particulate filter (4102) into the filter housing (4112) over the carbon Above the filter (4104), the particulate filter (4102) is secured using a filter holder assembly (450) and a front filter (4100) is attached to the particulate filter (4102). In this particular embodiment, the filter holder assembly (450) is somewhat different than the filter holder assembly (50) discussed above with respect to the ATS (10). In this embodiment, the bottom of the particulate filter (4102) is fastened by a clasp (452) that fits into a hollow (4120) in the filter housing (4112) and has a clip (454) at the top. (or latch) buckles interlocking with a locking projection (4126) extending from the filter housing (4112). The fifty-second A-D plot depicts the procedure for removing the particulate filter (4102) from the ATS (410). Figure 52A shows that the particulate filter (4102) has been installed and the clip (454) is in the closed position. The fifty-second C-picture shows that the top of the particulate filter (4102) is tilted away from the ATS (410). The tilting action of the filter (4102) also unwinds (or substantially unfastens) the cleat (452) from the void (4120). The fifty-second D-picture shows that the particulate filter (4102) is removed from the ATS (410). In the depicted embodiment, the clip (454) is configured such that when it is closed, the particulate filter (4102) is pulled tightly toward the filter housing (4112). This helps to compress one side of the particulate filter (4102) (not shown) to the shoulder (4114) to promote a hermetic seal.

Referring to Figures 51A through C, the cleat (452) is placed in the center of the bottom of the frame of the particulate filter (102). The cleat (452) of this embodiment is integrally molded with the frame of the particulate filter (4102), but it can alternatively be separately formed and attached to the frame. The buckle (452) of the depicted embodiment has a quarter-circular cross-section that facilitates the installation and removal of a corresponding void (4120) from within the filter housing (4112). The size, shape and configuration of the cleats (452) and voids (4120) may vary depending on the application.

In this embodiment, the clip (454) is rotatably mounted near the top center of the frame of the particulate filter (4102). The buckle (454) includes a handle (4122), a tooth (4130), and a hook (4124). The teeth (4130) are configured to engage the locking pin (4128) as the cleat (454) is turned into the closed position. More specifically, the intersection between the teeth (4130) and the locking pin (4128) causes the buckle (454) to be snapped into the closed position. Further, the hook (4124) is configured to engage the locking projection (4126) as the cleat (454) is turned into the closed position. In the depicted embodiment, the position and configuration of the hook (4124) and the locking projection (4126) are selected such that the buckle (454) provides a cam-like function when the buckle (454) When closed, the particulate filter (4102) is pulled into the filter housing (4112). The operation of the buckle (454) is shown in Figures 53A through D. In the fifty-third A diagram, the buckle (454) is shown in the open position and the hook (4124) is unwound from the locking projection (4126). First Fifty-three B shows that the clip (454) rotates clockwise into a portion of the closed position. The fifty-third C-picture shows that the clip (454) is further clocked into a position in which the hook (4130) is about to engage the locking pin (4128). Finally, the 53rd D picture shows the buckle (454) in the closed position. It can be seen that the teeth (4130) have moved beyond the locking pin (4128) and now resist the removal of the buckle (454) out of the closed/locked position. Moreover, the hook (4124) has been moved into engagement with the locking projection (4126). The engagement between the hook (4124) and the locking projection (4126) pulls the particulate filter (4102) completely into the filter housing (4112).

In this particular embodiment, the front filter (4100) is secured to the particulate filter (4102) using a somewhat different configuration than the incorporated ATS (10). As shown in the thirty-fourth diagram, the front filter frame (4116) includes a pair of tabs (4304) at the bottom and a pair of slotted tabs (4306) at the top. As shown in Figures 51A through C, the particulate filter (4102) includes a pair of slotted legs (4300) at the bottom and a pair of fingers (4302) at the top. The fingers (4302) are configured to be locked in engagement with the slotted tabs (4306). For example, the fingers (4302) can be tilted upward from the particulate filter frame. In use, the front filter (4100) is fixed to the particulate filter (4102) by first inserting the tab (4304) on the bottom of the front filter frame into the groove of the bottom leg (4300) of the particulate filter (4102). Then, the top of the front filter (4100) is tilted inward toward the top of the particulate filter (4102) to press the slotted tabs (4306) against the fingers (4302) on top of the particulate filter (4102).

Control System

The ATS (410) includes a control system (412) that controls the operation of the ATS (410) and provides a user interface for displaying information and receiving input from the operator. The main function of the control system (412) is to control the speed at which the ATS (410) is to be operated, process the air according to the measured parameters or user input, track the use of the filter, notify the operator mode, and set the motor speed to And filter life, and accept operator instructions. The control system (412) includes a user interface implemented as a "electroless board" display (416) that displays information and receives operator input regarding system operation and maintenance. The display (416) includes a plurality of display elements (418) that are visible only when illuminated to provide a varying dynamic display to provide information and to present control options available at any given time (compare the fortieth and Forty-one picture). As with the display (16) discussed above, the display (416) of the ATS (410) includes information indicating that the display element (418a) is illuminated to provide information about the ATS status, or a monitored characteristic, and an input display element. (418b) incorporates a touch sensor to allow an operator to provide input to the control system (412) (see FIG. 41). In addition to allowing user input, the input display element (418b) can also provide information about the status of the ATS, such as, for example, the mode of operation and the blower speed. The display (416) basically includes the same display elements (418) as the display (16) described above, except that the display elements (418) are placed in different places and the display (416) includes an additional display element to indicate when the display (416) uses an integrated WiFi transceiver to communicate with an external network.

The control subsystem (460) includes control circuitry and firmware configured to operate the ATS (410) and coordinately collect data from various other subsystems, including capacitive touch sensor arrays (464). ), a dust sensor (480), an RFID subsystem (468), and a wireless communication subsystem (470). The various modes of operation of the system will be described in more detail later. Referring now to the schematic representation of Figure 36, the electronic component module (414) generally includes a decentralized control configuration having a main application controller (510) and a touch detection controller ( 512), a light emitting diode driver controller (514), and a radio frequency identification controller (516). The main controller (510) is connected to the dust sensor (480), the radio frequency identification subsystem (468) (including the radio frequency identification controller (516) and a radio frequency identification antenna (518)), and the wireless communication subsystem (470) ( Includes a Bluetooth module (520) and a WiFi The module (522) and the electronic components constituting the display (including the LED driver controller (514) and the touch detection controller (512)). The main controller (510) is also coupled to the blower motor power supply (530) to allow the main controller (510) to control blower speed and, in some applications, to receive from the blower motor power supply (530) Feedback. The main application controller (510) is also coupled to a buzzer (524) for providing audible output, a universal non-synchronous transceiver (UART) connector (526) for diagnostic and non-volatile memory, such as Such as electronic erasable programmable read-only memory (EEPROM) (528) for storing programmed operational preset values as well as historical operational data such as filter life, usage time, counters, and Other variables used to relate to the operation of ATS (410). The touch detector controller (512) is electrically coupled to a capacitive touch key defined by a plurality of capacitive lines (532) and electrically coupled to a peripheral light sensor (534). In use, the touch detection controller (512) monitors the capacitive line and the ambient light sensor (534) and provides touch/near information and ambient light information to the main application controller (510). An LED driver controller (514) is coupled to the LED array (462). In operation, the LED driver controller (514) can illuminate individual LEDs in the LED array (462) in accordance with instructions received from the main application controller (510).

The control system (412) is incorporated into a self-contained electronic component module (414). Referring now to Figures 37 to 39, the electronic component module (414) for the ATS (410) generally includes a base (4150), a dust sensor cover (4152), and an electronic component. (550) and a partition (474). In this embodiment, the base (4150) is mounted to the filter housing (4112) and provides a configuration upon which various components of the electronic component module (414) are mounted. The base (4150) includes an electronics assembly (not shown) that allows the electronic component (550) to be mounted to the bottom surface of the base (4150), for example, by screws that pass through the mounting tab (552) (not shown). The pedestal (4150) also includes a dust sensor compartment The dust sensor (480) is housed (560) and provides a first-class diameter to direct air through the dust sensor (480). The flow path generally includes a sensor inlet (482), a sensor channel (484), and a sensor vent (486). The sensor inlet (482) can be closed by a dust barrier (562) to prevent large particles from soiling the dust sensor (480). A dust sensor (480) can be enclosed in a pair of rubber half-shells (488a) and (488b) that cause a leak-tight seal around the dust sensor (480). The dust sensor cover (4152) can define a plurality of airflow openings (564) that allow air to flow out of the dust sensor compartment (560) into a position upstream of the particulate filter (4102). It must be noted that the dust sensor flow path is a system description for the partial vacuum created by the air blower (456) to draw air along the dust sensor flow path into the ATS (410). Alternatively, if the air released by the ATS (410) through the exhaust port (4108) causes more of the airflow opening (564) in the dust sensor cover (4152) at the sensor inlet (482) than the blower in the dust sensor cover (4152) A large partial vacuum, through which air can flow in the opposite direction through the dust sensor flow path.

The electronic component (550) for the ATS (410) generally includes a bottom printed circuit board (566), a light guide (472), and a top printed circuit board (568) (see Figure 39). The bottom PCB (566) can support the circuit and circuit components as a whole, including various controllers and LED arrays (462). The array of light emitting diodes can include a plurality of individual light emitting diodes (462a) that can be selectively illuminated at the appropriate time. Each of the light-emitting diodes (462a) may comprise a single light-emitting diode, or a plurality of light-emitting diodes may provide various illumination options. In this embodiment, each LED associated with the filter life display element can include a red LED and a green LED; each LED associated with the ATS display component, the power display component, and the line display component can include a white LED; and the blower speed Each of the LEDs associated with the display element, the accelerated mode display element, the WiFi display element, and the dust sensor mist sensor element may include a blue LED and a blue LED; the LED associated with the first dust level may include a red LED , a green LED and a yellow LED; and the second and second dust Each level-related LED may include a red LED and a yellow LED; each LED associated with the fourth and fifth dust levels may include a red LED, and each LED associated with the night mode display element may include a red LED and a White LED. As with ATS (10), the array of light-emitting diodes (462) can be replaced or assisted by other types of light sources, such as, for example, OLEDs, electro-radiation, and EL sources.

The light guide (472) provides a mounting configuration for the PCBs (566) and (568) and includes a plurality of light pipes (472a) that direct light from the LED array (462) on the bottom PCB (566) through the top PCB (568) The opening is to illuminate the display element (418) on the spacer (474). The light pipe (472a) is configured to cause an optical flow path from the LEDs (462a) to the corresponding display element (418). The light pipes (472a) can be separated from each other independently to prevent light from leaking from an LED (462a) to an adjacent display element (418). The surface of the light pipe (472a) can be coated or textured to create dispersed light.

The top PCB (568) is mounted on the light guide (472). The top PCB (568) defines a plurality of light openings (570) and a plurality of lines (532) that function as capacitive touch sensors. In this particular embodiment, the top PCB (568) includes a separate light opening (570) for each display element (418) (see Figures 38 and 39). The size, shape and configuration of the light opening (570) may vary from application to application, for example, depending on the desired lighting effect. As noted above, the control system (410) includes a plurality of capacitive touch sensors (464). The design and configuration of the capacitive touch sensors may vary depending on the application. For example, each capacitive touch sensor can include a pair of electrodes and the touch can be identified by monitoring the mutual capacitance between the pair of electrodes. As another example, each capacitive touch sensor can include a separate electrode and the touch can be identified by monitoring the self-capacitance of the electrode. Referring now to the thirty-ninth aspect, a line (523) (or a pair of lines) extends around respective light openings (570) associated with an input display element (418b). More specifically, a conductive line (532) (or a pair of lines), such as, for example, a copper conductive element, is along with The periphery of each of the light openings (570) associated with the input display element (418b) is raised. The size, shape, span, and other aspects of the configuration of each of the conductive traces (532) can vary from application to application to provide the desired touch characteristics. In addition, the top PCB (568) may include an additional conductive trace (532b) intended to sense a user's proximity. As shown in the thirty-ninth diagram, the proximity sensor line (532b) can be a relatively large line that extends along a substantial portion of the top PCB (568). In use, the touch controller (512) can monitor various conductive traces (532) to determine when a touch or proximity event occurs.

In this particular embodiment, the control system (412) includes a separate baffle (474) that covers the entire display element (418). The spacer (474) is a laminated construction comprising substantially a astigmatism layer and a masking layer. The astigmatism layer disperses the light generated by the LEDs. The mask layer shields the light to create the desired pattern, including various opaque and translucent materials such as, for example, black water, lacquer, film, and other adhesive layers. In the depicted embodiment, the mask layer is placed on the other side of the astigmatism layer relative to the LED or other source, but it can be placed elsewhere if desired. While the mask layer and astigmatism layer depict a portion of a single laminate construction in a particular embodiment, they can alternatively be individually separate components. For example, they can be fabricated separately and placed adjacent to one another during assembly of the display (416).

The operation of ATS (410) will now be described with reference to the forty-second and forty-third figures. A forty-second diagram is an illustration of a display (416) showing the outline of all display elements (418), including an indication display element (418a) and an input display element (418b). Figure 43 shows a series of illustrations of displays (416a-m) in different modes of operation. In the depicted embodiment, the display (416) can be in three different states when the power is off. When the ATS (410) is unplugged or otherwise unreceived, the display is completely blank as shown on the display (416a). The ATS (410) is plugged in, but there is no power and no user is nearby. The display components (618a-c) are illuminated to show a line across the display. The indicator (416) is shown as a display (416b). The ATS (410) is plugged in, but is not powered and the user is nearby, and the display elements (618a-c) and (608) are illuminated to display a line and a power map, as shown by the display (416c).

The control system (412) can determine that a user is nearby by monitoring the capacitive line (532b). The control system (412) and the near line (532b) can be configured to determine when a user is nearby using various alternatives. In the depicted embodiment, the control system (412) and the near line (532b) are configured to determine that a user is nearby when the user comes within about twelve inches of the line (532b), for example That is, the user's hand is swung within about twelve inches of the window (433) above the display (416). The size, shape and configuration of the line (532b) and/or the sensitivity of the control system (412) to the sensed changes in the line (532b) may be varied to increase or decrease how close a user must be to the system for making There is a conclusion that the user is nearby. The control system (412) can determine if a user is not nearby depending on how long it has passed since the display (416) has received the user input. For example, each time the user input event occurs, the control system (412) can reset a countdown timer. A user input event may occur each time a user touches a touch key line (532) or each time a user comes within close proximity of the nearby line (532b). If the countdown timer reaches zero, the control system (412) concludes that no user is nearby and adjusts the display accordingly (416). The control system (412) can then begin to continue monitoring the near line (532b) to determine when a user has returned to a distance sufficiently close to the display (416). In addition, if a touch key line (532) is touched by a user, the control system (412) can also conclude that a user is nearby.

Once the power is turned on, the display (416) can operate in a variety of alternative states. The ATS (410) is in manual mode and all display elements are moderately illuminated when a user is nearby, such as Display (416d) is shown. Display elements (618a-c) are illuminated to show the line. Display element (608) is illuminated to display a power map. The display element (614) is illuminated to display a night mode image. Since the ATS (410) is not in night mode, the display element (614) is illuminated in white. Display element (606), including the dust icon (606a) and the appropriate dust level indication (606b) are illuminated. Since the ATS (410) is not in the automatic mode, the dust icon is illuminated in white. Moreover, because the dust level is low enough, only a single dust level indicator (606b) is illuminated and the illumination is green. Display element (616), including blower graphic (616a) and appropriate blower speed indication (616b), is illuminated. Because the ATS (410) is in manual mode, the blower icon (616a) is illuminated in blue. All blower speed indications (616b) are illuminated, the indication representing the actual blower speed is illuminated in blue and the higher blower speed achievable is illuminated in white. Display element (612) is illuminated to white to indicate that the ATS (410) is not in an acceleration mode. The filter life display elements (600, 602, 604), including the ATS diagram (605), are illuminated. In this example, all filters have a remaining life and are thus illuminated in green.
