摘要： Two-wire dimmer operation includes applying first and second control pulses to a switching circuit controlled between ON and OFF states, the first control pulse beginning at a first starting time and extending for a first duration of time that ends at a first ending time, and the second control pulse beginning at a second starting time, after the first ending time, and extending for a second duration of time that ends at a second ending time, detecting levels of current provided to a lighting load during the first duration of time and during the second duration of time, comparing current levels determined based on applying the first and second control pulses, based on the comparing, ascertaining a load type of the lighting load, and selecting, based on the ascertained load type, parameters that control dimming operation of the dimmer.

摘要： An apparatus includes an interruption circuit in a power delivery path, and a fault detection circuit configured to provide a fault signal to selectively cause the interruption circuit to interrupt power delivery, wherein the fault detection circuit includes a fault detection integrated circuit and a sensing coil configured to sense a differential current between a phase conductive path and a neutral conductive path in the power delivery path. A processor is configured to selectively control a fault simulation circuit to simulate a fault in the power delivery path, detect a response of the fault detection circuit to the simulated fault, and determine if the response of the fault detection circuit is an expected response. The processor provides an override signal to the interruption circuit to prevent the interruption circuit from receiving a fault signal from the fault detection circuit during, and for a predetermined time after, the simulated fault.

摘要： Timer-based switching circuit synchronization in an electrical dimmer is provided. The energizing of a switching circuit in a dimmer is synchronized with an AC wave to facilitate providing by the dimmer electrical power to a load. The synchronizing includes starting a timer having a predetermined timeout, responsive to receipt of a zero-crossing signal. Responsive to receipt of a subsequent zero-crossing signal prior to reaching the timeout, the timer is restarted, and responsive to expiration of the timeout, a switching circuit is energized at a predetermined firing angle with respect to the zero-crossing signal to supply electrical power to the load.

摘要： A system and method are disclosed for using gas detection techniques to determine if a room is vacant or occupied, and to activate, dim or deactivate lighting based on a detected occupancy status. The system and method may monitor a concentration of a first gas using a gas sensor such as a CO2 sensor. The space may also be monitored using second and third sensors, and a vacancy status of the space may be based on the concentration of the first gas and information from the second and third sensors. The second and third sensors can be passive infrared sensors, ultrasonic sensors, gas sensors, microwave sensors, audio sensors, or video sensors. An electrical load associated with the space may be controlled based on the determined occupancy/vacancy status. Other embodiments are described and claimed.
