摘要： A method for determining a limit of a phase control power range includes applying a first gate pulse to a switch at a first firing angle near the limit of the power range, sensing the conductive state of the switch after the first gate pulse, and determining the limit of the power range in response to the conductive state of the switch. If the switch remains conductive after the first gate pulse, the first firing angle may be used as the limit of the power range. If the switch does not remain conductive after the first gate pulse, the limit may be determined by repeatedly incrementing the firing angle, applying a gate pulse to the switch at the incremented firing angle, and sensing the conductive state of the switch after each gate pulse until the switch is conductive after a gate pulse.

摘要： A light control system having a full range of dimming for smart-glass by providing an interface between an off-the-shelf dimmer and a electrochromic glass device is disclosed herein. The light control system or electrochromic glass control device acts as an interface that converts an asymmetric alternating current (AC) power signal from the dimmer device into a symmetric, amplitude controlled AC output signal for controlling the tint of the smart-glass device. The electrochromic glass control device includes a powerline interface circuit that receives the asymmetric AC power signal from the dimmer. A controller connects to the powerline interface circuit to generate a control signal responsive to the asymmetric AC power signal. Connecting between the dimmer and the controller, an output stage generates the symmetrical AC output signal responsive to the control signal to control the electrochromic glass device.

摘要： A passive infrared (PIR) wall switch is operable in a two-wire circuit to control power to a load. The PIR wall switch can include one or more PIR sensors with a low current two stage amplifier-filter. The PIR sensor(s) monitor infrared (IR) radiation. The amplifier can provide a pulse signal when an IR radiation level has changed. Power for control circuitry of the PIR switch may be derived from a ground leakage type power supply, which can supply phase line wire leakage current to ground of less than 0.5 milliampere.

摘要： A modular toggle mechanism assembly has a housing assembly, a toggle handle pivotally mounted in the housing assembly and movable between a first position and a second position, biasing means for selectively biasing the toggle handle in the first position or the second position, and an actuator arm connected to the toggle handle and capable of selectively actuating an external switching device as a function of the position of the toggle handle. The modular toggle assembly also includes an external switching device in selective association with the toggle handle. The housing assembly includes an upper housing and a lower housing configured to be secured together, wherein a portion of the toggle handle extends from an opening in the upper housing for user operation of the handle. The biasing means is a toggle spring positioned in the lower housing, and the assembly further includes a toggle arm extending from the toggle handle which contacts at least a portion of the toggle spring when the toggle handle is moved between the first and second positions. The toggle spring is a flat spring member located in a channel and supported on substantially distal ends by a pair of support arms. The toggle arm makes contact with substantially the middle of the spring member through a predetermined arc defined by the rotational movement of the toggle arm.
