    • A method and apparatus are provided for detecting occupancy in an area using multiple detection technologies (e.g., ultrasound and infrared sensing) to intelligently control switching of plural load circuits whereby one of the circuits is affected by photocell control. A programmable controller implements auto-on, manual-on, reversion to auto-on and override operations with respect to the separately controlled load circuits based on sensor outputs and user inputs. An improved power supply for an occupancy sensor and load control device employs a DC voltage derived from leakage AC voltage between line and ground to drive the sensors and other circuits, and a switching regulator with a switching cycle controlled by a pulse width modulated (PWM) subsystem of the apparatus, allowing synchronous, delayed or exclusive operation relative to the sensing technology such as the US transmitter.

    • A control method for a sensor-less, brushless, three-phase DC motor. A pulse-width modulation (PWM) duty cycle may be calculated. A voltage induced by rotation of a rotor may be sampled at a first expected zero crossing value to produce a first sampled voltage value. An average of a plurality of sampled voltage values, including voltage values sampled at a plurality of prior expected zero crossing values and the first sampled voltage value, may be calculated. The first sampled voltage value may be subtracted from the calculated average to produce a delta zero crossing error (ZCE). The current value of an integral term corresponding to a rotational period may be updated according to the sign of the ZCE. The integral term may be updated periodically and multiple times during each rotational period. The ZCE may be subtracted from the integral term, and the resulting value may be used to generate one or more time values. Operation of the motor may be controlled based on the one or more time values and the PWM duty cycle.
    • 无传感器,无刷,三相直流电机的控制方法。 可以计算脉冲宽度调制(PWM)占空比。 可以在第一预期过零值处对由转子旋转引起的电压进行采样,以产生第一采样电压值。 可以计算多个采样电压值的平均值,包括在多个先前预期过零值处采样的电压值和第一采样电压值。 可以从所计算的平均值中减去第一采样电压值以产生增量零交叉误差(ZCE)。 可以根据ZCE的符号更新与旋转周期对应的积分项的当前值。 积分项可以在每个旋转周期期间周期性地更新多次。 可以从积分项中减去ZCE,并且可以使用所得到的值来生成一个或多个时间值。 可以基于一个或多个时间值和PWM占空比来控制电动机的操作。
