Abstract: A dual voltage power supply is disclosed for vehicles equipped with a DC generator, a single storage battery, a low voltage load circuit including the storage battery, and a high voltage load circuit including load devices designed to be powered by voltages higher than the battery voltage. At times when higher voltage power is required a low voltage regulator that includes a high current semiconductor switch converts power at the generator output voltage to power at a lower voltage for charging the battery and supplying the low voltage load circuit. There is a single voltage mode of operation when higher voltage power is not required in which the alternator is regulated to supply power at the voltage required by the low voltage load circuit and the high current semiconductor switch is held in its closed state to directly connect the generator output with the low voltage load circuit. The low voltage regulator is a switching DC to DC voltage converter with an N channel mosfet power transistor switch controlled by an improved driver circuit. The driver circuit has a floating totem pole output and a capacitively coupled input and is assisted by a pull down circuit and current from a low current supply. An input accepts a signal controlling whether the system operates in dual or single voltage mode. One or more transient absorbing semiconductors and a circuit for rapidly decreasing rotor current limit the duration of alternator overvoltage.

Abstract: A crash sensor for automobiles of the type including a ball moving against viscous damping in a closed cylinder for releasing a firing pin for initiating a pyrotechnic sequence has an improved release mechanism. When the ball moves a predetermined distance from its normal or resting position during an automobile crash it initiates a cascade of releases of increasingly larger and more powerful snap disks. The firing pin is mounted on and driven by the largest snap disk.

Abstract: An electrically energized power steering system for vehicles is disclosed using a clutch that disengages the servomotor at times of near zero driver input torque. The servomotor is energized for power assist in executing turns and for synchronizing servomotor speed with the steering mechanism during the return of the dirigible wheels to the straight ahead position and at other times when the clutch is disengaging the servomotor thereby eliminating clashing upon clutch reengagement. A torque transducer operatively coupled with the steering wheel shaft and the steering gear generates a torque signal corresponding to the torque applied by the driver to the steering wheel. Two tachometers are provided, one on the servomotor and one on the steering wheel shaft and the outputs are combined to develop a signal corresponding to differential speed. The torque signal and the differential speed signal are added and the resultant signal is applied to the servo amplifier which energizes the servomotor. When the driver turns the steering wheel the clutch engages the servomotor, the torque signal predominates and the servomotor is energized to provide power assist. When the driver releases the steering wheel, the torque signal drops to approximately zero and the differential speed signal controls the energization of the servomotor to maintain its speed in near synchronization with the return of the dirigible wheels to the straight ahead position.

Abstract: A dual voltage power supply for a vehicle is disclosed with a DC generator, a single storage battery, a low voltage load circuit including the storage battery and a high voltage load circuit including load devices designed to be powered by voltages higher than the battery voltage. A high voltage regulator is responsive to the generator output voltage and controls the energization of the field winding of the generator for causing the generator to produce an output voltage meeting the requirements of the high voltage load circuit. A low voltage regulator receives the output voltage of the generator and produces a substantially constant regulated voltage for charging the battery and supplying the low voltage load circuit.
