The outline of the invention described above and the detailed description of the following embodiments will be more clearly understood by reference to the accompanying drawings. In the present specification, the elements or steps described in the singular form do not necessarily exclude a plurality of elements or steps. Also, reference to "one embodiment" is not intended to exclude the existence of another embodiment incorporating the features described in that embodiment. Further, unless otherwise specified, an embodiment that "includes" or "has" one element or elements having a particular property may additionally include another element that does not have that property.

In some embodiments of the present disclosure, UV light in a far UV light spectrum, eg, a wavelength of 222 nm, that neutralizes (eg kills) bacteria (eg, viruses and bacteria) without harming humans. Disinfection systems and methods are provided that include emitting ultraviolet (UV) lamps (eg, excimer lamps having one or more light emitting devices such as light emitting diodes and light bulbs). Optionally, the UV lamp may emit UV light in a UVC spectrum, such as a wavelength of 254 nm. UV lamps can be used in internal cabins to eliminate and kill pathogens. The UV lamp can be used in a portable sterilization system or a fixed sterilization system. For example, the task of manipulating a UV lamp to emit germicidal UV light having a far UV spectrum or a wavelength within the UV spectrum may be performed in a portable system or a fixed system.

The effectiveness of the UV sterilization system is determined by the dose required to kill the pathogen of interest (eg, ^{expressed in mJ / cm 2).} Dose is a function of the optical power (in watts) and exposure time of UV light. In some embodiments of the present disclosure, a pacing guide that provides the user with a marker (eg, a visual cue generated by changing the ranging light) to inform the user of the appropriate time of exposure to germicidal UV light. The system is provided. According to embodiments of the present disclosure, the user can pace the movement of the wand assembly during sterilization to emit UV light in an amount suitable for disinfection. The embodiments of the present disclosure can guide the user according to the required irradiation dose and / or the specific item to be sterilized.

In some embodiments of the present disclosure, a method of pacing UV disinfection on a predetermined surface is provided. The method comprises calculating the speed of the wand and loading the speed into a computer program. The program can provide a visual cue (eg, changing ranging light) about the speed at which the wand is moved, as well as provide feedback to help the user maintain that speed.

In at least one embodiment, the visual cue is a variable light emitted from a ranging light source. For example, a ranging light source emits ranging light to the surface of a component to be sterilized. The ranging light is alternately stopped and driven to provide a visual cue for the speed distribution of the wand assembly to the surface of the component. For example, the ranging light can blink at predetermined intervals to provide a timing cue for moving the wand assembly relative to the surface of the component. As another example, the color of the ranging light may be changed at predetermined intervals to provide a timing cue. As another example, the intensity of the ranging light may be changed at predetermined intervals to provide a timing cue.

To calculate the time required to disinfect a surface, enter known parameters such as distance to the surface, irradiance of the wand, disinfection energy required to disinfect the surface, wand length, and wand width. The speed of is calculated.

The speed of movement of the UV wand determines the exposure time and typically determines whether the appropriate dose required to disinfect the surface can be achieved. For example, if the UV wand moves too fast to the surface, it may not be able to effectively sterilize the surface of the component. In some embodiments of the present disclosure, UV light allows the user to pace the movement of the UV wand assembly via a light pulse from a range-finding light (eg, an LED range-finding light source). A pacing system is provided.

In at least one embodiment, the UV optical pacing system traverses a series of temporally different UV wand assemblies (eg, 3 seconds, 4 seconds, 5 seconds, or) across the area to be sterilized, regardless of length. It is divided into subzones that are sterilized (eg, disinfected) by a 6 second pass motion), thereby guiding UV disinfection of the area to be sterilized. The pace of movement of the UV wand is guided by the pulse frequency of the ranging light source.

In some embodiments of the present disclosure, a system for pacing UV disinfection over a predetermined surface is provided. The system includes a UV wand assembly with a ranging light source that emits ranging light on the surface of the component. The ranging light source is controlled to emit ranging light that emits a pulse of a specific frequency, for example, at predetermined intervals in order to provide a visual cue for pacing the UV cleaning rate. A pacing control unit, such as an integrated circuit, controls the pulse time. In at least one embodiment, the area to be disinfected is divided into predetermined zones based on known dimensions, each subzone passing the UV wand assembly through one or more set times, regardless of length (. For example, it is disinfected by performing a passing motion for 3 seconds at least once).

In some embodiments of the present disclosure, methods for disinfecting the surface of a component are provided. This method selects the subzone to be disinfected, determines the number of passages of the set time required to disinfect the subzone, selects an appropriate time with a selector, and makes a variable range light source. Based on this, it involves sweeping the UV wand assembly over the entire subzone and repeating the sweep operation over a determined number of passes.

In some embodiments of the present disclosure, systems and methods are provided for pacing surface disinfection using a portable UV wand assembly to provide an appropriate amount of UV irradiation. The system and method provide a visual cue using a ranging light source to inform the user of a suitable time to sweep the UV wand assembly over a given subzone.

FIG. 1 shows a schematic block diagram showing a UV optical pacing system 100 according to an embodiment of the present disclosure. The UV optical pacing system 100 includes an assembly, such as a wand assembly 102 with one or more ranging light sources 130 and a UV lamp 140. Alternatively, the ranging light source 130 may be separate from the wand assembly 102 and may be located, for example, in a separate housing used with the wand assembly 102. The ranging light source 130 is configured to emit the ranging light 131 to the surface 104 or the like of the component 106 to be disinfected. The UV lamp 140 is configured to emit UV light 141 to the surface 104 in order to disinfect the surface 104. Optionally, the assembly may be something other than a wand assembly. For example, the assembly may be part of a system that includes an arm, a boom, a disk, a shield, etc., including a UV lamp 140.

As described herein, the UV light pacing system 100 includes a wand assembly 102, which is configured to emit UV light 141 to disinfect the surface 104 of the component 106. including. One or more ranging light sources 130 are configured to emit ranging light 131. At least one embodiment of the ranging light 131 (eg, emission duration and / or frequency, light) to provide a visual cue to guide the operation of the wand assembly 102 and disinfect the surface 104 of the component 106. Color, light intensity, etc.) may be changed. In at least one embodiment, the ranging light source 130 is fixed to the wand assembly 102.

Further, as described herein, the UV optical pacing method comprises emitting ranging light from one or more ranging light sources 130 of the wand assembly 102, wherein the wand assembly is the surface 104 of the component 106. Includes a UV lamp 140 configured to emit UV light 141 to disinfect. The above method provides at least one embodiment of the ranging light 131 (eg, emission duration and / /) to provide a visual cue to guide the operation of the wand assembly 102 and disinfect the surface 104 of the component 106. Or it further includes changing the frequency, the color of the light, the intensity of the light, etc.).

In at least one embodiment, the ranging light source 130 may be a light emitting diode (LED). The ranging light source 130 emits ranging light 131 to visually indicate an appropriate distance (ie, range) between the wand assembly 102 and the surface 104 for the purpose of effectively disinfecting the surface 104. do. In at least one embodiment, the wand assembly 102 includes a plurality of ranging light sources 130. For example, the wand assembly 102 includes at least a pair of related ranging light sources 130. In at least one other embodiment, the wand assembly 102 includes a single ranging light source 130.

The UV lamp 140 emits UV light 141 at a predetermined wavelength. For example, the UV lamp 140 emits UV light 141 within the far UV spectrum. For example, the UV lamp 140 emits UV light 141 at a wavelength of 222 nm. As another example, the UV lamp 140 emits UV light 141 within the UVC spectrum.

The pacing control unit 150 communicates with the ranging light source 130, for example, via one or more wired or wireless connections. In at least one embodiment, the pacing control unit 150 is provided within the wand assembly 102. That is, the wand assembly 102 includes the pacing control unit 150. In at least one other embodiment, the pacing control unit 150 may be remote from the wand assembly 102, eg, a desktop or laptop computer or a portable smart device (eg, a smartphone or tablet). It may be provided in the device.

The pacing control unit 150 is configured to operate one or more ranging light sources 130 to change at least one aspect of the ranging light 131. In order to properly and effectively disinfect the surface 104 by pacing or guiding the operation of the wand assembly 102 with respect to the component 106, the pacing control unit 150 controls the ranging light source 130 to change the ranging light 131. The modified light provides a visual cue that guides the pacing rate of movement of the wand assembly 102 relative to the component 106. For example, the pacing control unit 150 can selectively stop the driving of the distance measuring light source 130 at a predetermined timing for a predetermined time to generate blinking and / or a pulse of the distance measuring light 131. As an example, when the wand assembly 102 is activated to emit UV light 141 from the UV lamp 140, the pacing control unit 150 uses a timer to first stop driving the ranging light 131 at the initial time. Causes an initial blinking or stopping, and restarts the driving of the ranging light for a set time (for example, 1 second or 1.5 seconds), after which the pacing control unit 150 stops driving the ranging light again. Perform actions such as making it. In this way, the pacing control unit 150 operates the ranging light source 130 to generate a series of optical pulses at regular predetermined intervals (for example, by emitting light to the surface) of the wand assembly 102. Provide the operator with a visual timing queue. For example, if the time interval between the first drive stop of the distance measuring light source 130 (for example, the first blinking) and the second driving stop of the distance measuring light source 130 is 1 second, the operator can make each blinking. It can be determined that it represents one second. Thereby, if the effective time to move the wand assembly 102 relative to the surface 104 and disinfect the surface is 3 seconds in the length direction of the surface 104, the operator will at least after the first drive stop. It is determined that the wand assembly 102 is moved in the length direction of the surface 104 until three additional drive stops occur (a total of three pulses of ranging light 131 on the surface 104). Although optional, the time of each pulse of the ranging light 131 (that is, the driving time of the ranging light 131 during the drive stop (for example, blinking)) may be longer or shorter than 1 second. For example, the time of each pulse may be 1.5 seconds. As another example, the time of each pulse may be 0.5 seconds. As another example, the time of each pulse may be 2 seconds.

In at least one embodiment, the operator selects a time per pulse (eg, 0.5 second interval, 1 second interval, 1.5 second interval, 2 second interval, etc.) via the selector 152 of the user device 154. can do. That is, the selector 152 is configured to allow time selection for at least a portion of the visual cue, such as the pulse time of the ranging light 131. The user device 154 includes a user interface 156 with a display 158 and a selector 152. In at least one embodiment, the display 158 and the selector 152 are part of a touch screen interface. The selector 152 may be a virtual button, slide, switch, dial, or the like. Optionally, the selector 152 may be a physical button, slide, switch, dial, or the like.

In at least one embodiment, the user device 154 is an arithmetic unit such as a personal or laptop computer, a portable smart device (eg, a smartphone or smart tablet). In at least one other embodiment, the wand assembly 102 includes a user device 154. For example, the wand assembly 102 may include a handle with a user device 154. Also, in an alternative embodiment, the UV optical pacing system 100 does not include a user device 154.

Optionally, instead of the visual cue being an optical pulse, the color of the ranging light can be changed at predetermined intervals to provide a timing cue. As another example, the intensity of the ranging light may be changed at predetermined intervals to provide a timing cue.

In at least one embodiment, the UV optical pacing system 100 includes a pacing database 160 that communicates with the pacing control unit 150 and / or the user device 154, for example via one or more wired or wireless connections. In at least one embodiment, the pacing database 160 is provided within the wand assembly 102. For example, the wand assembly 102 may include a pacing database 160. In at least one other embodiment, the pacing database 160 is located away from the wand assembly 102.

The pacing database 160 stores surface disinfection data 162 for one or more surfaces of one or more components. The surface disinfection data 162 includes information on the UV light dose, the distance (including the distance between the wand assembly 102 and the surface 104, and / or the length of the surface 104), and the time of disinfection with the UV light 141. .. For example, the surface disinfection data 162 includes irradiation amount data 164 regarding the irradiation amount of UV light for disinfecting the surface 104, and distance data 166 regarding the distances related to the wand assembly 102 and the surface 104 for disinfecting the surface 104. And time data 168 relating to the time of disinfection using the UV light 141 emitted by the UV lamp 140. The pacing database 160 may store surface disinfection data 162 for a plurality of surfaces 104 of the plurality of components 106. For example, the surface 104 may be one or more zones or subzones in the internal cabin of a vehicle such as a commercial aircraft.

In at least one embodiment, the surface disinfection data 162 may be different for each of the various pathogens to be killed, removed, neutralized, etc. during the disinfection process. For example, the surface disinfection data 162 for Covid-19 has specific dose data 164, distance data 166, and time data 168 for a specific surface 104, which are different for influenza, salmonella, MERS, etc. It may be different from the dose data 164, the distance data 166, and the time data 168 for the pathogen.

During operation, the operator of the wand assembly 102 refers to the surface disinfection data 162 for the particular surface 104 to be sterilized to determine the appropriate pace distribution of the wand assembly 102 to the surface 104. Surface disinfection data 162 can be shown in a guidebook. As another example, the operator can select a specific surface to be disinfected via the selector 152 of the user interface 156, and the display 158 displays the surface disinfection data 162. For example, the operator may select a particular surface of the component via the user interface 156 to display surface disinfection data 162 for the selected surface.

In at least one other embodiment, the UV optical pacing system 100 includes a navigation subsystem 170 configured to track the position of the wand assembly 102 in an environment such as the vehicle's internal cabin. The navigation subsystem 170 may be a global positioning system (GPS) subsystem, a localized three-dimensional tracking subsystem, or the like. The navigation subsystem 170 communicates with the pacing control unit 150 via one or more wired or wireless connections. As the wand assembly 102 moves through the environment, the navigation subsystem 170 tracks the position of the wand assembly 102 with respect to the various components 106 in the environment. The pacing control unit 150 monitors the position of the wand assembly 102 in the environment via a signal received from the navigation subsystem 170. The pacing control unit 150 automatically determines the surface disinfection data 162 of the component 106 in close proximity to the wand assembly 102 based on the position of the wand assembly 102 with respect to the various components 106 in the environment and selectively determines the surface disinfection data. Can be displayed in. In this way, the pacing control unit 150 automatically performs surface disinfection data 162 for the various components 106 via the user interface 156 as the wand assembly 102 moves near (eg, 2 feet or less) the various components. Can be displayed as a target. Alternatively, the UV optical pacing system 100 may not include the navigation subsystem 170.

In at least one embodiment, the UV optical pacing system 100 includes an augmented reality subsystem 172.

During operation, the operator wears an augmented reality product. This augmented reality product displays, for example, a map of the environment, on which the actual environment is registered and / or superimposed. As the operator moves through the environment, the pacing control unit 150 can display surface disinfection data 162 for a particular component in an augmented reality product. For example, the pacing control unit 150 matches the actual component to the component in the saved environment map. Thereby, the pacing control unit 150 automatically displays surface disinfection data 162 and / or visual instructions for moving the wand assembly 102 to disinfect various surfaces as the operator moves through the environment. be able to.

Five images 2190 to 2194 are shown in FIG. 41, which show optical markers 2176 emitted from different distances to the target surface 2178 by a pair of 2172 ranging light sources 2130. ing. FIG. 41 shows an embodiment in which the relative position of the optical marker 2176 provides the user with guidance as to whether or not the sterilization head 2106 is located at a desired distance from the target surface 2178 for effective disinfection. It is shown. For example, first image 2190 shows an optical marker 2176 at a distance of 1.0 inch from surface 2178. The second image 2191 shows the optical marker 2176 at a distance of 1.5 inches from the surface 2178. The third image 2192 shows an optical marker 2176 at a distance of 1.75 inches from the surface 2178. The fourth image 2193 shows the optical marker 2176 at a distance of 2.0 inches from the surface 2178, and the fifth image 2194 shows the optical marker 2176 at a distance of 2.5 inches from the surface 2178. These distances refer to the distance between the UV lamp 2140 and the region of the target surface 2178 illuminated by the UV light emitted from the UV lamp 2140. The optical marker 2176 includes a first optical marker 2176A and a second optical marker 2176B, each of which has a different color, and is emitted by a different ranging light source 2130 in a single pair 2172. For example, the first optical marker 2176A may be amber and the second optical marker 2176B may be blue.

In the illustrated embodiment, the two ranging light sources 2130 at pair 2172 are intentionally oriented such that the light beams emitted from the light sources intersect at a distance of 1.75 inches. This focusing distance may be determined based on the characteristics of the UV light and / or the disinfection characteristics. For example, the focusing distance can represent the distance at which the desired disinfection is performed by UV light to kill or neutralize the pathogen. If the sterilization head 2106 is held too close to the target surface 2178, for example 1.0 inch as shown in image 2190, the first marker 2176A and the second marker 2176B have little or no overlap. Almost independent in the absence. The absence of overlap can be visually confirmed by the user, indicating that the sterilization head is not in the correct position. The user moves the markers 2176A and 2176B together by moving the sterilization head 2106 closer to or further away from the surface 2178. In this case, as shown in image 2191, by moving the sterilization head 2106 away by 1.5 inches, the markers 2176A and 2176B partially intersect to form an overlapping region 2196. The overlapping region 2196 is an region illuminated simultaneously by both ranging light sources 2130 in pair 2172. The color of the overlapping region 2196 may be a different color from the individual markers 2176A, 2176B, for example a lighter color or a whiter color. As the sterilization head 2106 moves further away from the surface 2178, the size of the overlap region 2196 increases until the distance is 1.75 inches, as shown in image 2192. In image 2192, the two markers 2176A and 2176B almost completely overlap to form essentially one optical marker instead of two. This large overlapping area 2196 (eg, a single marker) indicates to the user that the sterilization head 2106 is located at the desired height or distance from the subject surface 2178 for effective disinfection.

When the sterilization head 2106 is further moved away from the target surface 2178, the individual amber and blue optical markers 2176A and 2176B become visible and move away from each other, as shown in images 2193 and 2194. As a result, the overlapping region 2196 becomes smaller. The visual cues shown in images 2190 and 2194 are similar, but the user moves the sterilization head 2106 closer to or further away from the surface 2178 to determine whether the individual markers 2176A, 2176B approach or move away from each other. By observing, it is possible to quickly determine whether the sterilization head 2106 should be brought closer to or further away from the target surface 2178 in order to make the desired arrangement. If the markers 2176A, 2176B further branch, this means that the sterilization head 2106 should be moved in the opposite direction.

FIG. 42 is an end view of the sterilization head 2106, showing the optical marker 2176 on the target surface 2178 to be sterilized. FIG. 43 shows a side perspective view of the sterilization head 2106 used to sterilize and disinfect the instrument panel 2201. The optical marker 2176 illuminates the subject plane 2178 with two parallel rows 2202 and 2203. The two columns 2202 and 2203 allow the user to visually indicate the area to be disinfected. For example, the intervening region 2204 between the two rows 2202 and 2203 is irradiated with UV light from the UV lamp 2140. By bordering or surrounding the UV irradiation area 2204 with a ranging light source 2130, in addition to distance guidance in the depth dimension, the user can see which part of the target surface 2178 is UV irradiated (eg, disinfect). Can be determined at any time. The user may not be able to see the UV light itself.

FIG. 44 shows a plurality of relative angles between two ranging light sources 2130 in pair 2172, according to one embodiment. The LEDs used in the ranging light source 2130 can have a narrow divergence of 8-10 degrees. The relative angles 2184A, 2184B in the housing 2111 are predetermined based on the type of UV lamp 2140 used and the intended use of the disinfection system. For example, when disinfecting a flat surface such as a cabin region in a vehicle, the desired distance between the UV lamp 140 having a wavelength of 222 nm and the target region may be 1-3 inches including the endpoints. .. In one embodiment, the desired distance may be about 2 inches. The ranging light sources 2130 at pair 2172 may be set at an angle of about 53 degrees from each other based on a predetermined distance between them. At this angle, the light beams emitted from the two light sources 2130 intersect in front of the sterilization head 2106 at a distance consistent with the desired distance, for example 2 inches. Thus, if the markers intersect in overlapping regions as shown in image 2192 of FIG. 41, this indicates to the user that the sterilization head 2106 is at a distance 2205 suitable for the intended use from the target surface.

For example, when disinfecting a surface with protrusions, such as an aircraft flight deck, the desired distance between the UV lamp 2140 with a wavelength of 222 nm and the target surface may be 3 to 6 inches including the endpoints. good. The desired distance 2206 may be about 4 inches (eg, within 5%, 10%, or 15% of 4.0 inches). At the same predetermined distance, the ranging light sources 2130 at pair 2172 may be set at an angle of about 28 degrees from each other. At this angle, the light beams emitted from the two light sources 2130 intersect in front of the sterilization head 2106 at a distance consistent with the desired distance, for example 4 inches. Thus, if the markers intersect in overlapping regions as shown in image 2192 of FIG. 41, this indicates to the user that the sterilization head 2106 is at a distance 2206 suitable for the intended use from the surface of interest.

FIG. 45 shows three ranging light sources 2130 according to an alternative embodiment. The sterilization head 2106 may include at least a pair of ranging light sources 2130 arranged in the first subset 2207 and at least a pair of ranging light sources 2130 disposed in the second subset 2208. Each of the subsets 2207 and 2208 may include a pair or pair of ranging light sources 2130. The pair in the first subset 2207 is oriented at a different relative angle than the pair in the second subset 2208. For example, the pair in the first subset 2207 has a first relative angle of about 53 degrees 2184A and the pair in the second subset 2207 has a second relative angle 2184B of about 28 degrees. To operate the first subset 2207 without the second subset 2208 for the first use and to operate the second subset 2208 without the first subset 2207 for the second use, via the user or an automated control system. The ranging light source 2130 may be selectively controlled. The first use may be to clean the cabin area within the vehicle and the second use may be to clean the flight deck of the aircraft.

Optionally, at least one ranging light source 2130 may form part of two different pairs. For example, in the illustrated embodiment, the first ranging light source 2130A, the second ranging light source 2130B, and the third ranging light source 2130C are shown. The second and third ranging light sources 2130B and 2130C may emit light of the same color such as blue light. The first ranging light source 2130A and the second ranging light source 2130B form a pair of the first subset 2207. Further, the first ranging light source 2130A and the third ranging light source 2130C form a pair of the second subset 2208. The third ranging light source 2130C represents one of an alternative set of LEDs along one side of the housing 2111. The second and third ranging light sources 2130B and 2130C are provided on the same side of the housing 2111 but at different angles, which allows the user to switch the optimum disinfection distance based on the application. be able to. It is also possible to install a switch to change the focus from 2 inches to 4 inches (switching from blue LED 1 to blue LED 2) depending on the desired distance without changing the red LED 2130A.
