Definitions
- Wi-Fi capable light bulbs or Wi-Fi enabled light switches.
- Wi-Fi enabled light switches typically require replacement of the entire light switch, which potentially requires access to household AC voltages. Understandably, many homeowners are incapable or unwilling to perform such re-wiring.
- FIG. 4 is a top, plan view of one embodiment of remote controlled switch cover assembly
- FIG. 5a is a perspective view of the remote controlled switch cover assembly shown in FIGs. 1-4, showing a switch toggle member in a neutral position
- a remote controlled switch cover assembly may be used to convert a standard, existing toggle switch to one that can be controlled remotely, for example wirelessly using a keyfob or by using a smartphone, tablet, or other personal electronic device through via a local gateway device, or via the Internet and a local gateway device, in instances where the controller is located remotely from the toggle switch.
- a remote controlled switch may be controlled via a local security panel or home automation gateway, either alone or in conjunction with the aforementioned wireless devices.
- the remote controlled switch cover assembly is used in conjunction with a standard toggle switch used to apply and remove household AC voltages to electrical devices such as lights or other common household appliances or devices.
- FIG. 3 illustrates a side, cutaway view of one embodiment of remote light switch cover assembly 100, installed over an existing, standard toggle switch assembly 206.
- toggle cover 216 is slidably seated between toggle light switch member 204 and custom switch cover 214.
- Two prongs 300 extend downward from toggle cover 216, spaced far apart enough to allow toggle light switch member 204 to seat between the prongs 300.
- toggle cover 216 may be positioned up and down within cutout 302 of custom switch cover 214, causing toggle light switch member 204 to change state as toggle cover 216 is positioned between an "on" or up position and "off or down position.
- toggle cover 216 is not used, and toggle light switch member 204 protrudes through cutout 302, allowing direct manipulation of toggle light switch member 204 by a user to manually operate standard toggle switch assembly 206.
- switch position member 210 is shown having a longitudinal member 410 with ends 412 and 414 located at opposing ends of longitudinal member 410, an upper horizontal member 416 and a lower horizontal member 418.

- one or both toggle position switches may be used to determine the position of toggle light switch member 204. If only one position switch is used, it may be inferred that standard toggle switch assembly 206 is in an on or off condition when the one position switch is activated and in an opposite condition when the one position switch is deactivated. In one embodiment, signals from one or both switches are used by processing circuitry 202 to determine when toggle light switch member 204 has been placed into one position or the other, in order to stop rotation of motor 400, as will be explained later herein.
- remote controlled switch cover assembly 100 One of the benefits of remote controlled switch cover assembly 100 is the ability to allow manual manipulation of toggle light switch member 204 by a user without damaging various components of remote controlled switch cover assembly 100, such as gear train 402, motor 400 or switch toggle member 208.
- switch toggle member 208 resides in a "neutral position” after moving toggle light switch member 204 to an "on” or “off position remotely. This position allows a user to manually turn toggle light switch member 204 to an opposite position without interference from moving switch toggle member 208. Referring to FIG.
- switch toggle member 208 After switch toggle member 208 has placed toggle light switch member 204 into the off position, motor 400 begins turning the opposite direction, causing switch toggle member 208 to rotate counter-clockwise back to the neutral position, shown in FIG. 5a, with first end 406 resting against or near a lower surface of toggle light switch member 204
- the receiver when a command is received from a remote device instructing remote controlled switch cover assembly 100 to turn lights on, the receiver receives the wireless signal from the device and provides a downconverted baseband signal to motor control circuitry, such as a processor and/or discreet components such as one or more transistors, capacitors, resistors, etc. and power circuitry capable of rotating motor 400.
- motor control circuitry such as a processor and/or discreet components such as one or more transistors, capacitors, resistors, etc. and power circuitry capable of rotating motor 400.
- the power circuitry then provides a power signal to electric motor 400, typically a low-power DC motor, which causes electric motor 400 to rotate in a first direction, which in turn causes motor drive gear 401 to turn in a first direction.
- Motor drive gear 401 is in mechanical communication with gear train 402, which comprises a gear ratio that effectively reduces the speed of electric motor to a lower speed for use in moving switch toggle member 208.
- Gear train 402 is in mechanical communication with switch toggle member 208 via teeth 426, which causes switch toggle member 208 rotate in a first direction, causing toggle light switch member 204 to move to either the on or off position.
- the motor control circuitry receives a signal from toggle position switch 404 when switch toggle member 208 has moved far enough to cause standard toggle switch assembly 206 to change state.
- the number of rotations of motor drive gear are counted or a rotational position of one or more gears of gear train 402 are determined to indicate that standard toggle switch assembly 206 has been placed in a different state.
- one or more gear hubs of the gears of gear train 402 could comprise one or more deformities, for example knobs or cams, that may interact with a position switch similar to position switches 422 or 404 as described in US patent application serial number 14/825, 117, owned by the applicant of the present disclosure, the entire contents of which are incorporated herein.
- the deformities are located on the hub(s) at such points to coincide with a desired limit of movement of switch toggle member 208, either up or down, as well as a point indicative of the neutral position.
- the transceiver is part of a transceiver/receiver combination, such as one of a variety of transceivers widely available in the marketplace today.
- the circuitry may provide one or more types of information periodically, such as once per hour, or upon receipt of a command from a remote device to provide one or more types of information.
- the remote controlled switch cover assembly may turn toggle light switch member 204 on or off as a result of receiving a signal from a remote device, indicative of when activity is detected in a room.
- a stand-alone motion sensor could sense motion in a room, and then report that finding to a home security panel. The home security panel might then transmit a command to remote controlled switch cover assembly 100 to turn toggle light switch member 204 to the "on" position.
- the stand-alone motion sensor is located in one room (such as a foyer) and remote controlled switch cover assembly 100 is located in another room, such as a living room, so that when the motion sensor detects movement, the home security panel can send a signal to remote controlled switch cover assembly 100 in the living room, so that the living room is lit, for example, when a person enters his/her home.
- remote controlled switch cover assembly 100 could be used in conjunction with a typical, manually operated light switch, such as in an application where hallway lighting is controlled by two switches, one located at each end of the hallway. This may be referred to by those skilled in the art as a "three-way circuit".
- remote controlled switch cover assembly 100 could transmit a status signal to a remote device such as a home security panel, home automation system, or internet gateway, with a light status of whether the hall light is "on" or "off.
- circuitry 202 provides a signal to motor 400 to turn the motor drive gear in a way that will turn cause switch toggle member 208 to move in a direction to place toggle light switch member 204 into an opposite position, in this example, in the "down" position.

- the processing circuitry 200 comprises a general-purpose microprocessor, microcontroller or microcomputer, well known in the art and/or a custom or semi-custom ASIC, and/or discrete components able to carry out the functionality required for operation of remote controlled switch cover assembly 100.
- Processing circuitry 200 is selected based on power-consumption properties and space considerations, as remote controlled switch cover assembly 100 typically operates on batteries and a small form factor is desirable.
- processing circuitry 200 In the case of a microprocessor, microcontroller, microcomputer or ASIC, processing circuitry 200 generally executes processor-executable instructions stored in one or more memories 602 that control the functionality of remote controlled switch cover assembly 100.
- Examples of memory 602 include one or more electronic memories such as RAM, ROM, flash memory, EEPROMs, UVPROMs, etc. or virtually any other type of electronic, optical, or mechanical memory device, but excludes propagated signals.

- position switch 700 provides a signal to processing circuitry 200 when toggle light switch member 204 is in the "on” position, e.g., as end 414 contacts position switch 700 via movement of toggle light switch member 204 to the "on” position by switch toggle member 208.
- processing circuitry 200 detects when switch toggle member 208 has actuated toggle light switch member 204, i.e., when switch toggle member 208 has been placed in either the "on” or “off position and/or when switch toggle member 208 has activated or deactivated position switch 404. This detection is performed in accordance with the teachings previously discussed above, in some embodiments, using position switch 404 and/or 700.

[001] The present application is a continuation-in-part of U.S. patent application No.
14/825,117 filed on August 12, 2015, which claims the benefit of U.S. Provisional Application No. 62/036,581, filed on August 12, 2014, the entirety of both which are incorporated by reference herein.
II. Field of Use
[002] The present application relates generally to the home automation and control arts.
More specifically, embodiments of the present invention relate to remote control of electrical devices.
III. Description of the Related Art
[003] Home automation and control has been gaining popularity in recent years, allowing homeowners to remotely monitor and control various devices in their home. For example, the Nest thermostat has revolutionized the home thermostat market by intelligently learning the usage habits of home occupants, while also allowing remote control of the thermostat via the Internet. Wi-Fi enabled light bulbs are becoming increasingly common, allowing remote control of lights. A variety of other remote control devices are available, including devices that open/close garage doors, turn on/off pool/spa equipment, turn on/off sprinkler systems, etc.
[004] The popularity of being able to control lighting is of particular interest to many consumers. However, it is generally necessary to purchase expensive equipment to enable such a feature, such as expensive Wi-Fi capable light bulbs, or Wi-Fi enabled light switches. Such Wi-Fi enabled light switches typically require replacement of the entire light switch, which potentially requires access to household AC voltages. Understandably, many homeowners are incapable or unwilling to perform such re-wiring.
[005] It would be desirable, therefore, to enable homeowners to retrofit their existing electrical switches in order to add remote control capabilities to turn lights and other electrical devices on and off without having to purchase expensive lighting equipment or having to replace entire light switches.

DETAILED DESCRIPTION
[0018] Embodiments of the present invention allow a conventional electrical switch to be converted into a remote-controlled switch simply and economically. In one embodiment, a conventional toggle switch is converted into a remote-controlled switch by simply replacing its switch cover with a switch cover in accordance with the teachings herein.
[0019] A remote controlled switch cover assembly may be used to convert a standard, existing toggle switch to one that can be controlled remotely, for example wirelessly using a keyfob or by using a smartphone, tablet, or other personal electronic device through via a local gateway device, or via the Internet and a local gateway device, in instances where the controller is located remotely from the toggle switch. In some embodiments, a remote controlled switch may be controlled via a local security panel or home automation gateway, either alone or in conjunction with the aforementioned wireless devices. In one embodiment, the remote controlled switch cover assembly is used in conjunction with a standard toggle switch used to apply and remove household AC voltages to electrical devices such as lights or other common household appliances or devices.
[0020] Fig. 1 is a perspective view of one embodiment of a remote controlled switch cover assembly 100, for use with a standard toggle switch commonly found in homes and
businesses to apply and remove power to lights or other common appliances or devices. Remote controlled switch cover assembly 100 in one embodiment is approximately 20 millimeters thick, 76 millimeters wide, and 114 millimeters long, as shown. It is designed to be placed over an existing toggle switch after its switch cover has been removed. This allows an easy retrofit to convert an existing toggle switch into a remote-controlled toggle switch, while still allowing the existing toggle switch to be operated manually.
[0021] Fig. 2 shows an exploded view of one embodiment of remote controlled switch cover assembly 100. It comprises a main body 200 that holds one or more batteries 201 (in this case 2 AA batteries) for providing power to electronics 202 located on or within main body 200, such as such as a receiver for receiving wireless signals to operate remote controlled light switch assembly 100, i.e., commands to move a toggle light switch member 204 of an existing, standard toggle switch assembly 206 from "on" to "off or vice versa, a switch toggle member 208 for manipulation of toggle light switch member 204, and a switch position member 210 for providing an indication of the position of toggle light switch member 204, e.g., "on" or "off, "up" or "down", "1 " or "0", etc. Main body 200 is installed over an existing toggle switch after its switch cover has been removed. The same switch cover used to cover the existing switch may be used to cover the main body, or a custom switch cover 214 may be used to fit the dimensions of the main body. In one embodiment, two holes 212 are formed through a surface of the main body 200 that align with cover mounting threads of standard toggle switch assembly 206, and two fastening devices, sized and shaped for placement through the two holes, respectively, and for engaging the mounting threads of standard toggle switch assembly 206 to secure remote controlled switch cover assembly 100 to standard toggle switch assembly 206. Installation of light switch cover assembly 100 is as easy as installing batteries into main body 200, and replacing the standard toggle switch cover of standard toggle switch assembly 206 with light switch cover assembly 100. In one embodiment, a toggle cover 216 may be used for placement over toggle light switch member 204 which is available to users of remote light switch cover assembly 100 to manually operate light switch cover assembly 100.
[0022] Fig. 3 illustrates a side, cutaway view of one embodiment of remote light switch cover assembly 100, installed over an existing, standard toggle switch assembly 206. As shown, toggle cover 216 is slidably seated between toggle light switch member 204 and custom switch cover 214. Two prongs 300 extend downward from toggle cover 216, spaced far apart enough to allow toggle light switch member 204 to seat between the
prongs 300. In this arrangement, toggle cover 216 may be positioned up and down within cutout 302 of custom switch cover 214, causing toggle light switch member 204 to change state as toggle cover 216 is positioned between an "on" or up position and "off or down position. In other embodiments, toggle cover 216 is not used, and toggle light switch member 204 protrudes through cutout 302, allowing direct manipulation of toggle light switch member 204 by a user to manually operate standard toggle switch assembly 206.
[0023] Fig. 4 is a top plan view of one embodiment of remote controlled switch cover assembly 100. Shown are main body 200, existing toggle light switch member 204, electric motor 400, motor drive gear 401, gear train 402, toggle position switch 404, switch toggle member 208 comprising a first end 406 and a second end 408, and switch position member 210, among others. Not all of these components are necessary in some embodiments.
[0024] Main body 200 may be placed directly over standard toggle switch assembly 206 after its existing switch cover has been removed, with toggle light switch member 204 in either an up or down position. In FIG. 4, toggle light switch member 204 is shown as being in the "up" position, which for discussion purposes, represents the "on" position. Main body 200 is secured to standard toggle switch assembly 206 via two screws 428 that are sized, shaped and spaced to standard-sized threaded cover mounting holes typically found on standard toggle switch assemblies.
[0025] After remote controlled switch cover assembly 100 has been installed over standard toggle switch assembly 206, second end 408 of switch toggle member 208 is situated just above an upper surface of toggle light switch member 204 when toggle light switch member 204 is in an "on" or "up" position, as shown. Alternatively, remote controlled switch cover assembly 100 could be placed over standard toggle switch assembly 206 when toggle light switch member 204 is in an "off or "down" position. Referring back to FIG. 4, switch position member 210 is shown having a longitudinal member 410 with ends 412 and 414 located at opposing ends of longitudinal member 410, an upper horizontal member 416 and a lower horizontal member 418. In one embodiment, distal ends of upper horizontal member 416 and lower horizontal member 418 are joined together by vertical member 420, forming a square frame through which toggle light switch member 204 is placed therethrough.
[0026] In the position shown in FIG. 4, end 412 is situated away from position switch 404, causing position switch 404 to be in a first condition, either "open" or "closed", depending on whether toggle position switch 404 is a normally open switch or a normally closed
switch. Toggle position switch 404 changes state as end 412 comes into contact with toggle position switch 404 when toggle light switch member 204 is placed into the "off position. Toggle position switch 404, thus, is used to determine the position of toggle light switch member 204 to be in an off position. In another embodiment, a second toggle position switch (not shown) may be located under end 414 when toggle light switch member 204 is in the "on" position. In this embodiment, one or both toggle position switches may be used to determine the position of toggle light switch member 204. If only one position switch is used, it may be inferred that standard toggle switch assembly 206 is in an on or off condition when the one position switch is activated and in an opposite condition when the one position switch is deactivated. In one embodiment, signals from one or both switches are used by processing circuitry 202 to determine when toggle light switch member 204 has been placed into one position or the other, in order to stop rotation of motor 400, as will be explained later herein.
[0027] One of the benefits of remote controlled switch cover assembly 100 is the ability to allow manual manipulation of toggle light switch member 204 by a user without damaging various components of remote controlled switch cover assembly 100, such as gear train 402, motor 400 or switch toggle member 208. As shown in Fig. 4, switch toggle member 208 resides in a "neutral position" after moving toggle light switch member 204 to an "on" or "off position remotely. This position allows a user to manually turn toggle light switch member 204 to an opposite position without interference from moving switch toggle member 208. Referring to FIG. 4, when a user manually turns toggle light switch member 204 off, toggle light switch member 204 does not move switch toggle member 208 due to the distance between first end 406 and second end 408 being spaced far apart enough to allow unfettered travel of toggle light switch member 204. The neutral position refers to a position of switch toggle member 208 approximately midway to toggle light switch member 204, approximated by a position of lower horizontal member 418. In other words, the neutral position refers to a position of switch toggle member 208 that allows toggle light switch member 204 to be manually positioned without moving switch toggle member 208.
[0028] When remote controlled switch cover assembly 100 is operated remotely (e.g., by receiving a wired or wireless signal from a remote device), switch toggle member 208 is moved by gear train 402 as it is turned by motor drive gear 401 of motor 400. When remotely turning toggle light switch member 204 off, motor 400 is energized to turn gear train 402 in one direction, causing switch toggle member 208 to rotate in a clockwise
direction, causing second end 408 to push down against the top surface of toggle light switch member 204 until either switch toggle member 208 is moved a predetermined distance to cause toggle light switch member 204 to change to the off position or until toggle position switch 404 changes state when end 412 contacts toggle position switch 404 when toggle light switch member 204 has moved to the off position. In other embodiments, switch toggle member 208 may be configured to move linearly up and down to operate on toggle light switch member 204, rather than rotationally as shown in the embodiment of FIG. 4. Rotation of switch toggle member 208 occurs as a result of teeth 426, formed onto a concave edge of switch toggle member 208, meshing with one of the gears of gear train 402, and turns as gear train 402 is rotated as a result of motor 400 and motor drive gear 401 operating on gear train 402.
[0029] After switch toggle member 208 has placed toggle light switch member 204 into the off position, motor 400 begins turning the opposite direction, causing switch toggle member 208 to rotate counter-clockwise back to the neutral position, shown in FIG. 5a, with first end 406 resting against or near a lower surface of toggle light switch member 204
[0030] Remote operation of remote controlled switch cover assembly 100 occurs when a user wishes to remotely manipulate toggle light switch member 204 to turn lights on or off for example, using a device which sends wireless signals to a receiver located on or within main body 200, such as a keyfob, smartphone, tablet, home automation gateway, security panel, etc. A receiver as part of electronics 202, or a separate receiver, receives wireless or wired signals from the device and provides the signals to circuitry that controls motor 400, and therefore motion of switch toggle member 208, in order to manipulate toggle light switch member 204 to the "on" or "off state. For example, when a command is received from a remote device instructing remote controlled switch cover assembly 100 to turn lights on, the receiver receives the wireless signal from the device and provides a downconverted baseband signal to motor control circuitry, such as a processor and/or discreet components such as one or more transistors, capacitors, resistors, etc. and power circuitry capable of rotating motor 400. The power circuitry then provides a power signal to electric motor 400, typically a low-power DC motor, which causes electric motor 400 to rotate in a first direction, which in turn causes motor drive gear 401 to turn in a first direction. Motor drive gear 401 is in mechanical communication with gear train 402, which comprises a gear ratio that effectively reduces the speed of electric motor to a lower speed for use in moving switch toggle member 208. Gear train 402 is in mechanical
communication with switch toggle member 208 via teeth 426, which causes switch toggle member 208 rotate in a first direction, causing toggle light switch member 204 to move to either the on or off position. In one embodiment, the motor control circuitry receives a signal from toggle position switch 404 when switch toggle member 208 has moved far enough to cause standard toggle switch assembly 206 to change state. In other embodiments, the number of rotations of motor drive gear are counted or a rotational position of one or more gears of gear train 402 are determined to indicate that standard toggle switch assembly 206 has been placed in a different state. At that point, motor control circuitry causes motor 400 to rotate in a second direction opposite of the first direction, which in turn causes motor drive gear 401 to turn in a second direction opposite of the first direction, causing switch toggle member 208 to rotate back to the neutral position. Electronics 202 determines when switch toggle member 208 is in the neutral position when it receives a signal from position switch 422, which changes state when second end 408 comes into contact with position switch 422. In one embodiment, second end 408 comprises an extension 424 which makes contact with position switch 422. In general, electronics 202 receives a signal from a sensor of some kind when switch toggle member 208 is in the neutral state.
[0031] Determination of when toggle light switch member 204 has been placed into either the "on" or "off position may be accomplished in a number of different ways. In one embodiment, one or more gear hubs of the gears of gear train 402 could comprise one or more deformities, for example knobs or cams, that may interact with a position switch similar to position switches 422 or 404 as described in US patent application serial number 14/825, 117, owned by the applicant of the present disclosure, the entire contents of which are incorporated herein. The deformities are located on the hub(s) at such points to coincide with a desired limit of movement of switch toggle member 208, either up or down, as well as a point indicative of the neutral position.
[0032] Remote controlled switch cover assembly 100 may additionally comprise means to transmit information to a remote location, such as a home security panel, home automation system, smartphone, tablet, or some other device. The means may form a portion of electronics 202. The type of information that may be transmitted may comprise the state of toggle light switch member 204 (e.g., "on" or "off, "up" or "down"), battery status (e.g., warning signal sent when battery is low), supervisory signal to indicate the presence and operational confirmation of remote controlled switch cover assembly 100, and/or a signal indicative of detected movement, e.g., by a motion sensor (not shown) optionally
integrated into remote controlled switch cover assembly 100. In this embodiment, the circuitry may provide information for transmission to a transmitter located within main body 200. In another embodiment, the transceiver is part of a transceiver/receiver combination, such as one of a variety of transceivers widely available in the marketplace today. Further, the circuitry may provide one or more types of information periodically, such as once per hour, or upon receipt of a command from a remote device to provide one or more types of information.
[0033] When used in conjunction with a motion sensor, for example an integrated PIR detector, the remote controlled switch cover assembly may automatically turn lights on or off when people enter or leave a room. When the motion sensor detects movement, indicative of activity in a room, the motion sensor may provide a signal to the circuitry, indicative of such. In response, the circuitry may cause electronic motor 400 to rotate in order to place toggle light switch member 204 into the "on" position. Similarly, if the motion sensor does not detect movement in the room for more than a predetermined time period, such as 10 minutes, the circuitry may cause the electric motor to rotate to turn toggle light switch member 204 to the "off position.
[0034] In a related embodiment, the remote controlled switch cover assembly may turn toggle light switch member 204 on or off as a result of receiving a signal from a remote device, indicative of when activity is detected in a room. For example, a stand-alone motion sensor could sense motion in a room, and then report that finding to a home security panel. The home security panel might then transmit a command to remote controlled switch cover assembly 100 to turn toggle light switch member 204 to the "on" position. In one embodiment, the stand-alone motion sensor is located in one room (such as a foyer) and remote controlled switch cover assembly 100 is located in another room, such as a living room, so that when the motion sensor detects movement, the home security panel can send a signal to remote controlled switch cover assembly 100 in the living room, so that the living room is lit, for example, when a person enters his/her home.
[0035] In another embodiment, remote controlled switch cover assembly 100 could be used in conjunction with a typical, manually operated light switch, such as in an application where hallway lighting is controlled by two switches, one located at each end of the hallway. This may be referred to by those skilled in the art as a "three-way circuit". In this embodiment, remote controlled switch cover assembly 100 could transmit a status signal to a remote device such as a home security panel, home automation system, or internet gateway, with a light status of whether the hall light is "on" or "off. Such a
determination may be made using a current-sensing device, such as a coil, integrated circuit, and/or other circuitry to sense current flowing through toggle light switch member 204 in conjunction with a known position of toggle light switch member 204 detected by toggle position switch 404. A storage device, such as an electronic memory, flip-flop, or discrete circuitry can be used to store the position of toggle light switch member 204, e.g., either "up" or "down". The same storage device, or a different one, may store the light status as well using the current sensor. Thus, at any time, remote controlled switch cover assembly 100 knows which position toggle light switch member 204 is in currently and whether the light is on or off. Then, if a command is received to either turn the light on or off from the device, the circuitry can determine whether switch toggle member 208 must be activated and, if so, what direction to move switch toggle member 208, depending on whether the command is to turn the light on or off and what position toggle light switch member 204 is currently in. For example, in a three-way application that uses a regular switch and remote controlled switch cover assembly 100, if toggle light switch member 204 is in an "up" position and the current sensor determines that current is flowing through toggle light switch member 204, an indication may be stored within the memory(ies), indicating that toggle light switch member 204 is in the "up" position and that the light is on. Thereafter, if the regular light switch is manipulated, turning the light off, the current sensor detects the loss of current, and the circuitry stores the current status of the light, i.e., "off in the memory. Then, if a command is received by remote controlled switch cover assembly 100 to turn the light on, the circuitry may read the memor(ies) to determine the present light status and know that the light is off, and that toggle light switch member 204 is in the "up" position. Knowing this, circuitry 202 provides a signal to motor 400 to turn the motor drive gear in a way that will turn cause switch toggle member 208 to move in a direction to place toggle light switch member 204 into an opposite position, in this example, in the "down" position.
[0036] FIG. 5b is a top, plan view of remote controlled switch cover assembly 100 showing switch toggle member 208 rotated counter-clockwise from the neutral position where it has just positioned toggle light switch member 204 into the "on" or "up" position. First end 406 is shown resting against a lower surface of toggle light switch member 204.
[0037] Conversely, FIG. 5c is a top, plan view of the same embodiment of remote controlled switch cover assembly 100 as shown in FIG. 5b, showing switch toggle member 208 rotated clockwise from the neutral position where it has just positioned toggle
light switch member 204 into the "off or "down" position. Second end 408 is shown resting against an upper surface of toggle light switch member 204.
[0038] Fig. 6 illustrates a functional block diagram of one embodiment of remote controlled switch cover assembly 100, shown comprising processing circuitry 200, memory 602, transceiver 604, electric motor 400, gear train 402, switch toggle member 208, current sensor 606, motion sensor 608, and motor driving circuitry 610. It should be understood that in some embodiments, not all of the functional blocks shown in FIG. 6 are necessary for the proper operation of the remote controlled switch cover assembly 100 and that some functionality has been omitted for purposes of clarity.
[0039] The processing circuitry 200 comprises a general-purpose microprocessor, microcontroller or microcomputer, well known in the art and/or a custom or semi-custom ASIC, and/or discrete components able to carry out the functionality required for operation of remote controlled switch cover assembly 100. Processing circuitry 200 is selected based on power-consumption properties and space considerations, as remote controlled switch cover assembly 100 typically operates on batteries and a small form factor is desirable. In the case of a microprocessor, microcontroller, microcomputer or ASIC, processing circuitry 200 generally executes processor-executable instructions stored in one or more memories 602 that control the functionality of remote controlled switch cover assembly 100. Examples of memory 602 include one or more electronic memories such as RAM, ROM, flash memory, EEPROMs, UVPROMs, etc. or virtually any other type of electronic, optical, or mechanical memory device, but excludes propagated signals. Memory 602 could alternatively comprise an integrated circuit, such as a flip-flop, or even discrete components, such as one or more transistors, resistors, capacitors, etc.
[0040] Transceiver 604 comprises circuitry necessary to transmit and receive communication signals, including messages, commands, status information, requests, etc., between remote controlled switch cover assembly 100 and one or more remote devices such as wireless phones, mobile computers and tablet computers, wearable devices, etc., either directly or through a local device such as a gateway, security panel, or home automation panel. Such circuitry is well known in the art and may comprise BlueTooth, Wi-Fi, RF, optical, or ultrasonic circuitry, among others.
[0041] Motion sensor 608 comprises any device that is able to detect movement of a person within range of remote controlled switch cover assembly 100. In one embodiment, a PIR detector is used, although other types of motion sensors may be used in the alternative, keeping the low power requirement of remote controlled switch cover
assembly 100 in mind. In another embodiment, motion sensor 608 comprises a passive infrared sensor. In other embodiments, motion sensor 608 may comprise a light-beam interruption detector, a sonic transducer, a reed switch or a pressure sensitive floor device.
[0042] Current sensor 606 comprises a device to detect the presence of alternating current that is conducted through toggle light switch member 204. Typically, current sensor 606 comprises a coil, integrated circuit, and/or discrete components to wirelessly determine changes in flux occurring as a result of a change in current through toggle light switch member 204. Current sensor 606 provides a signal indicative of the current to the processing circuitry 200.
[0043] The motor driving circuitry 610 is coupled to processing circuitry 200 and provides one or more relatively high power signals to motor 400 that cause motor 400 to rotate in one direction or the other. Such circuitry is well-known in the art.
[0044] FIG. 7 is a perspective view of the embodiment of remote controlled switch cover assembly 100 as shown in FIGs. 1-6. This view shows toggle light switch member 204 in an "on" position, with switch toggle member 208 shown in the neutral position. In this embodiment, position switch 700 provides a signal to processing circuitry 200 when toggle light switch member 204 is in the "on" position, e.g., as end 414 contacts position switch 700 via movement of toggle light switch member 204 to the "on" position by switch toggle member 208.
[0045] FIG. 8 is a flow diagram of one embodiment of a method for remote control of a standard toggle switch performed by remote controlled switch cover assembly 100 in accordance with the teachings herein. It should be understood that the steps described below could be performed in a different order, or comprise a greater or fewer number of steps in other embodiments, and that some minor method steps have been omitted for clarity.
[0046] At block 800, transceiver 604 (or a receiver in an embodiment where a transmitter is not used) receives a wired or wireless signal to actuate switch toggle member 208, to turn lights on or off, for example. The wired or wireless signal may originate from a smart phone, mobile computer, fixed computer, home automation gateway, security system, or some other device known in the art. The signal may comprise a specific instruction to turn a light on or off, or it may comprise an instruction to simply change the state of switch toggle member 208 from its current position to an alternative position.
[0047] At block 802, in response to receiving the signal at block 900, processing circuitry 200 activates electric motor 400 that causes gear train 402 to turn in a first direction,
commensurate with moving toggle light switch member 204 to a position indicated by the signal (e.g., "on", "off or "toggle"). In practice, processing circuitry 200 provides a signal to motor driving circuitry 610 which in turn provides a power signal to motor 400. This, in turn, causes gear train 402 to act on switch toggle member 208, causing switch toggle member 208 to move either up or down.
[0048] At block 804, processing circuitry 200 detects when switch toggle member 208 has actuated toggle light switch member 204, i.e., when switch toggle member 208 has been placed in either the "on" or "off position and/or when switch toggle member 208 has activated or deactivated position switch 404. This detection is performed in accordance with the teachings previously discussed above, in some embodiments, using position switch 404 and/or 700.
[0049] At block 806, in response to detecting when switch toggle member 208 has been placed in either the "on" or "off position and/or when switch toggle member 208 has activated or deactivated position switch 404, processing circuitry 200 causes electric motor 400 to rotate in a reverse direction (again, by providing a signal to motor driving circuitry 610) from the first direction, which causes switch toggle member 208 to reverse direction and move back towards the neutral position.
[0050] At block 808, processing circuitry 200 detects when switch toggle member 208 is in the neutral position, as previously discussed above. In one embodiment, a signal is provided by position switch 422 as extension 424 contacts position switch 422.
[0051] At block 810, in response to detecting when switch toggle member 208 is in the neutral position, processing circuitry 200 causes the electric motor to stop rotating (by sending a signal to motor driving circuitry 610), causing switch toggle member 208 to cease movement.
[0052] At block 812, processing circuitry may cause a signal to be transmitted via transceiver 604 to a remote location, such as a security panel, home automation gateway, smart phone, mobile computing device, etc., indicating the position of toggle light switch member 204, e.g. either "on" or "off.
[0053] The methods or steps described in connection with the embodiments disclosed herein may be embodied directly in hardware or embodied in machine-readable instructions executed by a processor, or a combination of both. The machine-readable instructions may reside in RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. An exemplary storage medium is coupled
to the processor such that the processor can read information from, and write information to, the storage medium. In the alternative, the storage medium may be integral to the processor. The processor and the storage medium may reside in an ASIC. In the alternative, the processor and the storage medium may reside as discrete components.
[0054] Accordingly, an embodiment of the invention may comprise a non-transitory processor-readable media embodying code or machine-readable instructions to implement the teachings, methods, processes, algorithms, steps and/or functions disclosed herein.
