Abstract: This invention relates to a power supply module that includes an input and an output, a power converter for supplying power from the input to the output, a controller for controlling the amount of power supplied from the input to the output in response to a feedback circuit, a module current sensing circuit for sensing module output current at the output, and a microprocessor for selectively adjusting voltage in the feedback circuit in response to the module output current sensed by the module current sensing circuit.

Abstract: A magnet is fixed to the inner surface of the ceiling of a cylinder-like yoke which is closed at the top, and a holding plate is attached to the yoke through a slider. A coil and collet are unitedly attached to the holding plate. When a current is passed through the coil, a force proportional to the current acts on the coil so that a constant load is applied to the collet.

Abstract: A crash detection apparatus of an air bag system comprises a detection unit for detecting acceleration caused therein by an automobile and outputting electric signals corresponding to the acceleration, a discrimination unit for discriminating, from the signals from the detection unit, a crash signal which is outputted on the basis of the acceleration caused by crash of the automobile, the crash signal being inputted into an inflator to inflate an air bag. The detection unit is a capacitance type semiconductor detector comprising a pair of fixed electrodes and a cantilevered movable electrode disposed between the fixed electrodes and fixed at an end thereof, and a servo control unit is electrically connected to the detection unit so as to form a negative feedback loop, of a detection signal.
