20110093094 | In-Wall Occupancy Sensor with RF Control - An electrical control system including a master device and a slave device wirelessly coupled to the master device. The master device includes an occupancy detection sensor that senses motion within a monitored area. The master device controls operation of the slave device when occupancy is detected within the area. The master device can be coupled to a first load while the slave device can be coupled to a second load. In one exemplary embodiment, the slave device can be controlled to activate the second load when occupancy is detected within the area. In one exemplary embodiment, the slave device can be controlled to deactivate the second load when occupancy is detected within the area. In one exemplary embodiment, the slave device can be controlled to activate the second load when the first load is activated by the master device based upon occupancy is detected within the area. | 04-21-2011 |
20110298392 | In-Wall Occupancy Sensor with Dimmable Night Light - An electrical wiring device includes a dimmable night light therein. The night light includes one or more light sources for emitting light and an optional lens disposed over the light sources. The lens allows light from the light sources to be emitted therethrough. In some embodiments, the lens is used to turn on the night light, turn off the night light, and dim the night light. In some exemplary embodiments, manipulation of the lens selects an operating mode for the device. The device optionally includes an occupancy detection sensor to assist detecting occupancy within a monitored area. | 12-08-2011 |
20110301776 | In-Wall Occupancy Sensor with Mode Selection Features - An electrical wiring device operates in more than one operating mode and includes a microcontroller, an occupancy detection sensor communicably coupled to the microcontroller, and at least one accessible user interface communicably coupled to the microcontroller. The accessible user interface is accessible to an end-user without having to disassemble any portion of the device. The accessible user interface is manipulated to select one of several operating modes. In some embodiments, the device includes a night light that also can be an accessible user interface. In some of those embodiments, one of the operating modes includes a night light operating mode, wherein the device's operation is dependent upon the status of the night light. In some embodiments, an indicator is included to inform the end-user when to stop manipulating the accessible user interface. | 12-08-2011 |
20120247935 | METHOD AND APPARATUS FOR A COMBINATION LIGHT PIPE AND AIR GAP SWITCH - An electrical switch device includes a housing, faceplate, and a light pipe assembly that includes a light transmissive channel, a position stop, and a cam. The device also includes an air gap switch having a movable contact assembly and a stationary contact assembly. The movable contact assembly includes a cam follower that engages the cam of the light pipe assembly. The light pipe assembly is configured to pulled outward from the outer surface of the faceplate. Movement of the light pipe assembly cause the cam follower of the movable contact assembly to move along the cam and separate the movable contact from the stationary contact, shorting the circuit. Pushing the light pipe assembly in a direction back into the faceplate causes the cam follower to move in the opposite direction along the cam and allows the movable contact to engage the stationary contact and close the circuit. | 10-04-2012 |
20120248990 | METHOD AND APPARATUS FOR A SWITCH HAVING A LIGHT PIPE FOR COMBINED LED DISPLAY AND LIGHT LEVEL SENSING - An electrical wiring device includes a manually adjustable switch, a light emitting diode (LED), a light level sensor, and a microcontroller. The wiring device also optionally includes an occupancy sensor. Light level is sensed through a light pipe and light is emitted by the LED through the same light pipe. When the manually adjustable switch is positioned to energize a load, the LED is deactivated and ambient light level is sensed by light sensors through the light pipe. The ambient light level is compared to a minimum ambient light level to determine if the load will be energized. Alternatively, the LED is deactivated and the ambient light level is sensed through the light pipe when the switch is positioned to de-energize the load. This ambient light level is stored and compared to the minimum ambient light level at a time when the switch is later positioned to energize the load. | 10-04-2012 |
20120256558 | Dimmer for Light Emitting Diodes and Fluorescent Bulbs - A dimmer system for a luminaire is provided. The dimmer system has a dimmer that receives a first current and supplies a reduced-magnitude current. The dimmer system also has a boosting system that receives the reduced-magnitude current and supplies a boosted current to a light source or lamp if the reduced-magnitude current is being received in conjunction with the initial turn-on of the dimmer. The boosted current can be provided for a predetermined period of time. The boosted current can also be provided as pulses of boosted current interspersed with pulses of the reduced-magnitude current. The boosted current can have the magnitude of the first current or range from 70% to 100% of the first current. | 10-11-2012 |
