    • A system for controlling a roller shade having a roller tube windingly receiving a shade fabric varies roller tube rotational speed for constant linear shade speed. The desired linear shade speed, roller tube diameter and shade fabric thickness and length are stored in a memory for use by a microprocessor. Preferably, the roller tube rotational speed is varied by the microprocessor depending on shade position determined by signals from Hall effect sensors. The microprocessor maintains a counter number that is increased or decreased depending on direction of rotation. Based on the counter number, the microprocessor determines shade position and a corrected rotational speed for the desired linear shade speed. Preferably, the microprocessor controls roller tube rotational speed using a pulse width modulated signal. The system may be used to control first and second roller shades having roller tubes of differing diameters or shade fabrics of varying thicknesses.
    • 用于控制具有卷绕式遮光帘布的辊管的卷帘的系统改变了用于恒定线性遮蔽速度的辊筒旋转速度。 所需的线性帘线速度,辊筒直径和帘布层厚度和长度存储在存储器中以供微处理器使用。 优选地,根据由霍尔效应传感器的信号确定的遮蔽位置,微处理器改变滚筒转速。 微处理器保持根据旋转方向增加或减小的计数器号。 基于计数器号码,微处理器确定阴影位置和校正的旋转速度以达到期望的线性遮蔽速度。 优选地,微处理器使用脉冲宽度调制信号来控制辊筒旋转速度。 该系统可用于控制具有不同直径的辊管或不同厚度的遮光织物的第一和第二辊子色调。

    • A dimmer circuit for providing AC power from an AC voltage source to an inductive lighting load disposed in series with the dimmer circuit, comprising: a bidirectional semiconductor switch having at least one control electrode provided with a control signal for controlling the amount of power provided to the load, the switch in normal operation being able to be controlled to block voltage in first and second opposite polarity half-cycles of the AC voltage source but in a failure mode being able to block the AC voltage source in only one polarity half-cycle of the AC voltage source and not being able to block the AC voltage source in the second opposite polarity half-cycle; a controller for the switch for determining if said failure mode of the switch occurs which can cause an asymmetry between the half-cycles delivered to the load and thus a DC voltage component to be delivered to the load; a power supply for supplying power to the controller and provided with power across the dimmer circuit; the controller controlling the switch if such failure mode occurs so as to: drive the switch into substantially full conduction during most of the half-cycle which the switch is able to control; and drive the switch into non-conduction for a brief duration of time during that same half-cycle so as to prevent a DC voltage component supplied to the load from exceeding a predetermined level below which excessive transformer heating does not occur, thereby minimizing overheating of the inductive load and enabling the power supply for the controller to be provided with sufficient voltage from the AC voltage source to enable the controller to continue to operate.
