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 starter drive is disclosed for a starting system of an internal combustion engine. A pinion is rotatably mounted on the starter motor shaft for engagement with the ring gear on the fly wheel of the engine. A drive sleeve disposed coaxially of the shaft is coupled with the pinion through an overrunning clutch. A helical cam and follower are connected between the shaft and the drive sleeve for advancing and retracting the pinion according to the relative speeds of the drive sleeve and the shaft. A friction brake is provided for the drive sleeve to restrain it against rotation during advancing movement of the starter drive. The starter motor has a permanent magnet field and the armature is connected across an electromagnet by the starter switch when it is turned off to provide dynamic braking for the motor. The electromagnet coacts with the permanent magnet brake to disable the friction brake while the motor is slowing down.

Abstract: An angular displacement transducer of the variable reluctance type is disclosed. It utilizes two relatively rotatable rotors with two sets of magnetic circuits and a coil associated with each magnetic circuit. Each set of magnetic circuits has a set of magnetic cores, one-half the cores on one rotor and one-half on the other rotor. A pair of cores in the first set, one on each rotor, coact with each other to provide a first variable reluctance magnetic circuit which is magnetically linked with the first coil and which has a reluctance that varies with relative rotation of the rotors. A pair of cores in the second set, one on each rotor, coact with each other to provide a second variable reluctance magnetic circuit which is magnetically linked with the second coil and which has a reluctance that varies with relative rotation of the rotors. The pairs of cores in the first and second sets are arranged so that relative rotation of the rotors causes the reluctance of the first magnetic circuit to increase while the reluctance of the second magnetic circuit is decreasing, and vice-versa.

Abstract: Sensors in a vehicle seat provide data for classifying occupants. Information from the sensors may be used to determine the position of an occupant relative to the seat and relative to the vehicle, the weight of the occupant, whether the seat belt is latched, and the position of the occupant relative to an airbag before and during a crash. Situations wherein airbag deployment is not desired are identified. A particularly inexpensive system meets the occupant classification needs of a system comprising a low risk deployment passenger airbag.

Abstract: An interfacial force microscope includes a differential-capacitance displacement sensor having a tip mounted on an oscillating member. The sensor generates displacement signals in response to oscillations of the member. A scanner is adjacent the sensor and supports a sample to be imaged. The scanner is actuable to move the sample relative to the sensor to bring the tip into intermittent contact with said sample as the member oscillates. A controller is in communication with the sensor and the scanner. The controller includes a sensor feedback circuit receiving the displacement signals and an AC setpoint signal. The AC setpoint signal has a frequency generally equal to the frequency at the peak of the displacement versus frequency curve of the sensor. The output of the sensor feedback circuit is applied to the sensor to oscillate the member. The controller also provides output to the scanner in response to the displacement signals to control the separation distance between the sensor and the sample.
