Patent ID: 8560261

Claim:
A sensor and light fixture, comprising: a housing; a sensor; at least one light emitting element (LED); an assembly supporting the sensor and the at least one LED; a data cable receptacle attached to the housing, wherein the data cable receptacle allows connection of a data cable, wherein the data cable carries a plurality of control signals from a remote device and an alternating current (AC) electrical power; a set of magnetics configured to isolate the plurality of control signals from the AC electrical power supplied by the data cable receptacle; a power circuit having a bridge rectifier circuit configured to convert the AC electrical power received from the data cable receptacle to a direct current (DC) power; and a power controller circuit configured to provide a plurality of DC power sources using the converted DC power; and a control circuit comprising a processing device, a network controller, and a memory storing a network address associated with the sensor and light fixture and local instructions, wherein the processing device is powered by a source of the plurality of DC power sources and configured to receive the plurality of control signals on the data cable addressed to the sensor and light fixture with the network address from the set of magnetics and execute the local instructions in response to the plurality of control signals to adjust aspects of the sensor; and execute the local instructions in response to an environmental input received from the sensor to adjust aspects of the at least one LED, wherein the sensor is powered by a source of the plurality of DC power sources and is configured to generate the environmental input and send the environmental input to the control circuit, and wherein the housing encompasses the sensor, the at least one LED, the assembly, the data cable receptacle, the set of magnetics, the power circuit, and the control circuit.
