Abstract: A wall plate system for an electrical device, including but not limited to indoor wall switches, includes a wall plate and a shield. The wall plate defines an aperture, and the wall plate is configured to receive a portion of an electrical device in the aperture. The shield extends at least partially through the aperture, and the shield is configured to form a seal between the wall plate and the electrical device.

Abstract: A system that provides communication using an antenna formed by a gap between a circuit board and a housing of a lighting fixture. A first end of the gap corresponds to a first grounding point that electrically connects the circuit board and the housing and a second end of the gap corresponds to a second grounding point that electrically connects the circuit board and the housing. The distance between the first grounding point and the second grounding point defines a length of the gap and determines an operational frequency of the antenna.

Abstract: Certain examples involve lighting systems controlled based on gas concentration data received by a controller. For instance, a lighting system includes a first light fixture to illuminate a first space. The lighting system also includes at least one gas concentration sensor associated with the first space, and a first controller that receives gas concentration data from the at least one gas concentration sensor. The first controller also overrides the illumination state of the first light fixture based on the gas concentration data received from the at least one gas concentration sensor by controlling the first light fixture in an alert state that is different from the illumination state.

Abstract: A luminaire includes: at least one digital sensor; an illumination element; a main power supply including driver functions configured to provide power to the illumination element; and an integrated digital lighting controller in communication with the main power supply and the at least one digital sensor. The integrated digital lighting controller configured to: receive digital signals corresponding to a sensed parameter from the at least one digital sensor; determine a lighting characteristic for the illumination element based at least in part on the digital signals from the at least one digital sensor; and generate one or more control signals to the main power supply to control the driver functions to provide power to the illumination element to produce the determined lighting characteristic.
