Granted: 1995-06-13
Abstract: A resettable circuit interrupter in a ground fault detector circuit utilizes a housing which slideably retains a solenoid coil wound on a bobbin.  A contact carrier is attached to the bobbin and one or more moveable contacts are provided on the carrier opposite a corresponding set of fixed contacts. A plunger slides through a central passageway in the solenoid coil.  The bobbin is spring biased so that the contacts are in a normally open position.  In a manually resettable version, when the solenoid coil conducts a predetermined current, manually activating the plunger causes the plunger to magnetically couple to a footplate attached to the bobbin.          When a plunger spring returns the plunger to its original position, the bobbin and contact carrier move with it and the contacts are closed.  When the solenoid coil conducts insufficient current to magnetically couple the plunger and footplate, the bias springs maintain the contacts in the normally open position.  In an electrically resettable version the contacts may be reset by electromagnetic energy alone, without manual activation of the plunger.

Title: Air bag firing circuit
Inventor: BEHR LEONARD W
IPC: B60R21/01
Filed: 1990-04-03
Granted: 1994-08-02
Abstract: An air bag firing circuit comprises a firing path including in series a safing sensor, a squib, and a crash  sensor.    Each  sensor  comprises  normally-open switch means operated by an inertial mass and shunted by a resistor.  A battery maintains a known voltage across the firing path while suitable control means checks the integrity of the firing path by reading and comparing the voltages achieved at various points thereabout.  The control means further tests each sensor individually by sequentially operating suitable test means incorporated therein, such as means for biasing the inertial mass of each sensor towards its switch means to operate same, while  determining  the  effect of such testing on the voltages  achieved about  the  firing path.   Upon  the detection of a sensor failure, the malfunctioning sensor is removed from the firing path as by operating low-resistance shunt means therefor, or by operating means incorporated within the sensor for operating the switch means thereof without regard to acceleration, such as means for biasing its inertial mass towards its switch means  to  close  same,  thereby  ensuring  continued protection of the vehicle passengers until the sensor is serviced or replaced.   If the malfunctioning sensor is the  high-threshold  crash  sensor,  the  control  means operates means on the low-threshold safing sensor to increase the threshold thereof upon removal of the crash sensor  from  the  firing  path,  thereby  providing continuing protection for vehicle passengers.

Title: Cross-connect method for stm-1 signals of the synchronous digital multiplex hierarchy
Inventor: POSPISCHIL REGINHARD
IPC: H04L5/22
Filed: 1990-08-29
Granted: 2001-06-05
Abstract: Cross-connect method far STM-1 signals of a synchronous digital multiplex hierarchy. Data blocks having differing multiplex structure of the synchronous digital multiplex hierarchy are processed in common in a cross-connect equipment. Controlled via a bus by a microprocessor, AU-4 administration units of STM-1 signals are resolved into virtual container groups of approximately the same length such as TUG-31 and TU-31. After the removal of auxiliary signals that are no longer required, an individual switching matrix network clock matching painter and an individual switching matrix network overhead are respectively attached to these virtual container groups for the formation of uniform switching matrix network input signals (D39, D52). After a rearrangement in a switching matrix network, switching matrix network clock matching pointers and overheads are again taken from the switching matrix network output signals and are evaluated. Subsequently, the input signals (D39, D52) are subjected to a corresponding multiplexing method for the formation of new STM-1 signals. This method is employable in cross-connect and drop insert multiplexing equipment.

Title: Controllable recloser for power line
Inventor: DUNK MICHAEL
IPC: H02H3/06
Filed: 1991-01-22
Granted: 2001-10-09
Abstract: An electronically controlled recloser for an electrical power distribution system is powered by at least one current transformer coupled to give an output in response to power line current. A voltage is stored on a large and a small capacitor in response to the line current and is compared with a reference voltage for determining the level of line current. When abnormally high levels of current appear on the line, it is opened for a short period of time. The energy stored on the capacitors is supplied to power the recloser during low line current conditions. At an end of a given time period following the opening of said line, the recloser recloses the line. If the abnormal condition persists, the recloser again opens and closes the line. When there is a surge of line current, the large capacitor is effectively removed from the circuit so that a response will not be delayed while the large capacitor charges; therefore, the charge on the small capacitor provide a quick start for immediate response. The circuit includes a novel circuit for converting a level of line current into a frequency which may be used by a microprocessor for selecting a mode of operations.
