摘要： A lighting control system for operating lighting in a room is provided. The lighting control system may comprise a load controller, sensors, and battery powered lighting control devices, such as switches, dimmers, and/or keypads. The load controller is configured for controlling the operation of a lighting load in response to messages received from the lighting control devices and sensors over a wireless network. The battery operated lighting control device is configured for detecting a low battery level, transmitting a low battery message to the load controller, and entering into a low battery mode during which it ceases transmitting any messages to the load controller until the battery is replaced. In response to the low battery message received from at least one lighting control device, the load controller is configured for entering into a low battery mode during which it maintains the lighting load turned on. The load controller is configured for exiting the low battery mode and resuming normal operation upon receipt of a subsequent message from the at least one lighting control device.

摘要： A lighting dimmer circuit that provides sinking and sourcing current outputs. The sinking and sourcing dimmer circuit may comprise first and second amplifiers, first and second NPN transistors, and first and second independent feedback loops. The dimmer is configured for providing a variable output voltage signal (Vout) to a sinking load or a sourcing load. When the output voltage signal (Vout) is coupled to a sinking load, current flows from a positive power supply (Vpos), through the first NPN transistor, and to the sinking load. When the output voltage signal (Vout) is coupled to a sourcing load, current flows from the sourcing load, through the second NPN transistor, and to the ground. In addition to the independent feedback loops, the gain of second amplifier may be greater than the gain of the first amplifier to ensure there is no undesired contention between the first and the second NPN transistor.

摘要： An occupancy sensor detects the occupancy state of a monitored area. The occupancy sensor may be mounted in a standard junction box at various angles and one or more of the ultrasonic sensors may be disabled. The occupancy sensor includes a PIR sensor and one or more ultrasonic sensors. The sensor sensitivities and timeout settings may be programmed by a technician or user via an IR interface or via a network interface. The settings may be changed according to control system logic or some other factor such as date, time or room conditions. Setup of the sensor may also be performed via the IR interface or network interface. The occupancy outputs both a signal taking into account the timeout period as well as a raw data signal. The IR interface may be used to relay messages between a control system and external devices. Algorithms employed in the occupancy sensor allow for the occupancy sensor to process analog signals from sensors to determine the room state, enhance performance such as by reducing false trips, enhance energy savings and force sensors into vacancy or occupancy mode. The occupancy sensor additionally comprises a microphone. Sound can be required to qualify detection from another sensor and may be employed to prolong the occupancy state once it is established.

摘要： A dimmer circuit for detecting a connected load type comprising a controller, a plurality of dimming transistors adapted to provide a dimmed hot output signal to a load, and a current sensor adapted to sense current levels of the dimmed hot output signal. The controller is adapted to store at least one load type current parameter associated with a dimming mode. The controller is further adapted to generate an asymmetric forward phase transistor drive signal with half cycles of one polarity having incrementally increasing dimming levels to drive the plurality of dimming transistors. The controller receives current levels from the current sensor and determines whether at least one of the received current levels satisfies at least one stored current parameter. When at least one current level satisfies at least one current parameter, the controller sets the dimmer to operate in a dimming mode associated with the satisfied current parameter. When the received current levels do not satisfy the stored at least one load type current parameter, the controller sets the dimmer to operate in a default dimming mode. The at least one current parameter may define one or more current events associated with a load type, such as an inrushing current event, double peaked current event, a lagging current event, or a substantially non-ratiometric current rise.
