    摘要： A control system and method for operating an automobile window to provide anti-trap protection in an AUTO UP mode, wherein a switch assembly communicates switch signals representative of operator commands by disposition in distinct positions. A sensor that detects when an object is trapped between the window and the frame, and transmits an anti-trap signal representative thereof. A logic circuit receives the switch signals and the anti-trap signal and controls the drive assembly for the window in response thereto. The switch assembly includes a switch to override the anti-trap sensor for closing the window even when an obstruction is sensed during the closing operation.

    摘要： A control circuit drives the coil of a contactor in response to a control voltage being applied. The control circuit includes a power supply that produces a regulated output voltage from the control voltage. The onset of the regulated output voltage starts a timer which controls the width of pulses produced by a PWM controller. The pulses control a transistor that applies the control voltage to the coil. Initially the pulses cause a high current to flow through the coil to close the contactor and after an interval of time the timer signals the PWM controller to shorten the pulses which applies lesser current to the coil to keep the contacts closed. A flyback circuit provides a relatively low reverse voltage drop path in parallel with the coil to maintain the electromagnetic field during the periods between the pulses. When the control voltage is removed to open the contactor, the flyback circuit provides a high reverse voltage drop path to promptly dampen the coil current.

    摘要： A power controller with overload protection having an alternating current source (AC) connected through power lines (L1, L2) and a pair of power switching devices (FET1, FET2) and a current sensor resistance shunt (SH) in series to a load (LD). A line-derived control power supply circuit (LDS) is connected through one of the power switching devices (FET1) to the lower line (L1, L2) such that the control power supply current does not flow through the shunt (SH) or the load (LD). Close and open commands are applied from a control switch (CSW) through a threshold detector (DT) and a logic circuit (LG1) to operate a latch (LCH) that turns the power switching devices (FET1, FET2) on and off under the clocking control of a zero voltage detector (ZVD) and a zero current detector (ZCD) and the gating control of a minimum current circuit (MCC). An overload circuit (AVC, ITC, TTC) provides instantaneous trip of the latch on rupture current or timed trip of the latch on smaller overloads. Opto-isolated indicators (SS, ST) indicate trip conditions and loss of line voltage conditions as well as whether the load current is above or below a minimum current value which is a current level adequate for operation of the control system.
