Abstract: A variable transient simulator employs a source of pulsating DC voltage for charging a first capacitance bank to a desired potential difference. After a device under test (DUT) is connected to a second capacitance bank, the charged-up first capacitance band is isolated from the DC voltage source and allowed to discharge into the second capacitance bank and, together, both capacitance banks provide discharging current into the DUT which simulates a desired loop during transient response. The simulator can provide repetitive as well as variable positive and negative transients.

Abstract: Locking a cable socket to a cable plug in a cable assembly is affected by integrally molding a lock assembly to the socket and plug housings. A pair of overstress brackets of the socket housing prevent a resilient latch of the lock assembly from breaking if excessive force is used to move the latch from a catch post mounted on the plug housing. Also, the overstressed brackets are formed in a manner that permits a single molding operation when forming the socket housing.

Abstract: A daytime running light system employs level sensing comparators to effect reduced illuminating the high beam filaments of headlamps of a vehicle and short circuit protection to the circuit as well as to a high beam indicator circuit which only operates when the high beam filaments operate at full intensity.

Abstract: A frequency conversion system for converting a pulse period into a frequency value by calculating a reciprocal value of a binary digit value of a pulse period from a remote period counter. The system uses the binary digit as a divisor and successively adds the divisor until a running sum results in (1) greater than a chosen dividend value or (2) the number of additions needed to reach a chosen dividend value is reached. A second embodiment is included which contains a local period counter.

Abstract: A radial type air-core gauge includes orthogonally positioned pairs of stator coils wound on independent coil forms spaced radially 90 degrees apart about a central cup of a gauge case. The cup houses a permanent magnet rotor which rotates about a shaft extending from a support bearing in a bottom surface of the cup to a hub of a dial pointer. Movement of the shaft causes a dial pointer to move over a dial face in response to changes of a balanced resultant field caused by variations of excitation signals applied to the stator coils.

Abstract: Operation of eight motors to control two power seats of a vehicle is effected by three rocker arm type switches, one "joy stick" type switch and a seat select switch. Each seat can be moved in ten different directions.

Abstract: A sensor communications network connects over a single-wire bus to smart sensors arranged in the latch mechanism of doors of a vehicle for lighting a courtesy light when the doors are open and for turning on an ajar indicator when the doors are ajar and/or open during the presence of the ignition voltage.

Abstract: A smart multiplex scanner system for scanning a matrix of switches utilizes counter of a chosen modulo value that counts to that chosen value for generating row and column enable signals that are used to sequentially scan the switches of the matrix.

Abstract: A bus receiver power-up synchronization circuit synchronizes the receipt of parallel data messages transferred asynchronously as three byte words preceded and succeeded by idle bytes so as to receive complete and not partial messages. Also, the receiver scrutinizes the messages for faults and for too many or too few bytes.

Abstract: A distance pulse unit measures the period between valid edges of asymmetrically shaped pulses from a distance pulse sensor. The unit counts individual clock pulse or averages eight individual clock pulses used to determine the period. The averaging occurs if the frequency of the sensor pulses are above a chosen frequency. The averaging aids in reducing the effects of the asymmetry of the sensor pulses.

Abstract: A wye-type air-core gauge system provides magnitude indications of measurands in response to PWM signals generated by a control unit that receives electrical signals from a sensor that represents magnitude variations of the measurand. The size of the stator coils of the gauge makes possible a very low profile gauge suitable for mounting in an instrument cluster.

Abstract: A combination illuminated entry and door lock switch for a vehicle door lock assembly which provides voltage signals to a single wire bus and smart sensor multiplex control system for controlling turning on interior lights of the vehicle when a door handle is operated and for disarming a vehicle alarm system when a door key is turned in a door lock cylinder. Another embodiment includes a keyboard mounted in a cavity of the door handle assembly which permits sending voltage signals over the single wire bus to the smart sensor multiplex control system to control a variety of drivers and other control devices.

Abstract: Combinational logic circuits are used with a temporary storage device holding data bytes to detect improper bits in both the lower and upper nibbles of the bytes. Combinations of bit patterns derived from both nibbles permit flagging the occurrences of a variety of bit errors existing in sequentially transmitted parallel data bytes.

Abstract: Continuous status monitoring of a plurality of switches and smart sensors associated with the switches, wherein each sensor is connected to a separate single point in a single wire bus is a affected by a smart sensor multiplex arrangement employing an automatic wake-up circuit. The automatic wake-up circuit allows activation of any switch of a group of high priority switches to automatically take a microcontroller out of a wait mode and causes it to go into a POWER-ON mode. In the POWER-ON mode, power routes all circuits in the entire system and then a polling of all the switches and sensor modules is performed.

Abstract: A smart multiplex keypad scanner system for scanning a matrix of switches utilizes a portion of a clock pulse to read the switch status of one of the switches in a matrix of switches in a system in which a standard counter of a chosen modulo value that counts up to a value one less than the number of switches in the matrix is employed to generate addresses of switches in the matrix.

Abstract: A terminal secondary lock bar effects locking of keepers in circular grooves of terminals disposed in rows above and below a lock bar receiving cavity arranged in an interior location within the housing of a plug and a socket of an in-line environmentally sealed cable assembly. The lock bar has two outer laterally directed semi-triangularly shaped fingers and at least one rectangular shaped finger disposed therebetween. The outer fingers are flexed inwardly upon insertion until a region of the cavity provides a lock reaction to the ends of the fingers which flex outwardly into the lock region of the cavity. The outer fingers are also flexed inwardly upon removal of the lock bar from the cavity.
