摘要： A load control device for controlling the power delivered from a power source to an electrical load includes an antenna and a communication circuit to receive and transmit messages via radio frequency (RF) signals. The communication circuit is coupled to the power source but is capacitively coupled to the antenna. The capacitive coupling is formed through multiple layers of a printed circuit board (PCB) in which each layer includes a conductive trace that neighbors another conductive trace on an adjacent layer. The capacitive coupling provides that the antenna is electrically isolated from the communication circuit which accordingly, provides that the antenna is electrically isolated from the power source.

摘要： A load control system comprises a load control device and a battery-powered occupancy sensor, which transmits a first wireless signal to the load control device in response to detecting the presence of an occupant in a space. The load control system further comprises a visual indicator for providing a visual indication when the magnitude of a battery voltage of a battery of the occupancy sensor has dropped below a predetermined low-battery voltage threshold. The occupancy sensor may comprise the visual indicator, such that the visual indicator is illuminated when the occupancy detects the presence of the occupant in the space and the magnitude of the battery voltage is less than the predetermined threshold. Alternatively, the load control device may comprise the visual indicator, such that the visual indicator is illuminated in response to receiving a second wireless signal, which is transmitting by the occupancy sensor when the magnitude of the battery voltage is less than the predetermined threshold.

摘要： A gate drive circuit for a controllably conductive device, such as a triac, includes a trigger circuit for conducting a gate current through a control input of the controllably conductive device, and a sense circuit operable to generate a control signal representative of the magnitude of the gate current. The controllably conductive device is adapted to be coupled in series between an AC power source and an electrical load for controlling the amount of power delivered to the electrical load. The controllably conductive device is operable to change from a non-conductive state to a conductive state in response to the gate current being conducted through the control input. A controller is operable to control the controllably conductive device via the gate drive circuit and to determine, in response to the magnitude of the gate current through the control input of the controllably conductive device, whether the controllably conductive device is presently conducting current to the load.

摘要： A smart dimmer for control of a lighting load from an AC power source can replace any switch in a three-way or four-way lighting control system. The smart dimmer can be connected on the line-side or the load-side of a three-way system with a standard three-way switch in the other location. According to one embodiment of the present invention, the dimmer includes two triacs to control the intensity of the connected lighting load. The dimmer preferably includes two gate drive circuits coupled to the gates of the triacs for rendering the triacs conductive each half-cycle of the AC power source. The gate drive circuits include sensing circuits for detect whether the gates currents are flowing after the triacs are rendered conductive. A controller is operable to determine the state of the lighting load in response to whether the gate current is flowing or not flowing.
