20140132084 | CONTROLLABLE ELECTRICAL RECEPTACLE WITH ROUTED ANTENNA - A controllable electrical receptacle is disclosed. The electrical receptacle includes a housing having a pair of sockets suitable for receiving electrical plugs. The receptacle includes an antenna disposed beneath a cover portion of the receptacle. The antenna is configured to receive wireless signals from an occupancy sensor or other controller and to control power to the sockets based on the received signals. The antenna is also configured to transmit wireless signals. The antenna may be routed around the sockets to minimize interference caused by metal components of the receptacle. The antenna may be sandwiched between a pair of non-metal layers of the housing to avoid direct exposure to the environment while maintaining a desired performance. In one embodiment the antenna is a wire member received within a routing groove formed in a portion of the housing. The routing groove includes features for retaining the wire member in the groove. | 05-15-2014 |
20140239817 | System and Method for Occupancy Sensing with Enhanced Functionality - A system and method are disclosed for providing fail-safe operation of a lighting system. A lighting level detector is used to obtain a baseline lighting level for a low-intensity light. If the detector measures less than the baseline level when an occupancy sensor determines the space is unoccupied, a high-intensity light is energized and an indication is provided to a user that the low-intensity light has failed. A method is also disclosed for daylighting operation of a lighting system. An occupancy sensor can have Wi-Fi functionality to enable remote configuration of the sensor. A line voltage occupancy sensor can include an interface with low voltage devices. An occupancy sensor can include an integral interface to enable an external control system to override the sensor's normal logic under emergency conditions. An occupancy sensor can include an active temperature compensation feature. An occupancy sensor can also incorporate an automatically adjustable coverage area. | 08-28-2014 |
