Title: Charge regulator for electronic device and associated method
Inventor: DEMURO DAVID MARK
IPC: H04B1/38
Filed: 1994-08-23
Granted: 1998-08-18
Abstract: An electronic device, such as a radiotelephone, is connectable to a variable-level power source (106). The electronic device includes a rechargeable power source (188) which is repowered responsive to application of operative power generated by the variable-leevel power source (106). The electronic device provides a constant charge current regulator (168) for converting operative power of a constant voltage into operative power of a constant current to be applied to the rechargeable power source (188) to recharge the rechargeable power source (188).  The constant charge current regulator (168) is made of a series connected diode (176) and resistor pair (172).  According to a further aspect of the invention, when the rechargeable power source becomes fully recharged, application of the operative power can be reduced by switching (206).

Title: Clutch reengagement control
Inventor: MACK WILLIAM J
IPC: B60W30/18
Filed: 1995-09-18
Granted: 2000-12-19
Abstract: A control is provided for controlling reengagement of a master clutch (16) in a vehicular automated mechanical transmission system. A nominal reengagement rate (CLU_RATE) is determined as a function of engine lag (K1), throttle position (THL), engine acceleration/deceleration (dES/dt) and/or input shaft acceleration/deceleration (dIS/dt). To provide smoother shifting during braking (BRK = 1, THL = 0) and/or coasting (THL < 30%) downshifts, the clutch is reengaged at a rate slower than the nominal reengagement rate.

Title: Electromagnetically actuated valve
Inventor: BULGATZ DENNIS C
IPC: F01L9/20
Filed: 1994-06-27
Granted: 1998-09-29
Abstract: An electromagnetically actuator (10) is disclosed having an electromagnet (12), a core element (16), the core element having a normally biased initial spaced apart first position distal from the electromagnet when the electromagnet is off and a second stop position proximal from the electromagnet when the electromagnet is on, a first resilient member (20) adapted to bias said core element in the normally biased first position, and a second resilient member (50) adapted to bias the electromagnet away from the core. The first resilient member is more resilient than the second resilient member. Therefore, the core approaches the electromagnet when the electromagnet is on until the core reaches the fixed stop position, and the electromagnet subsequently approaches the core to the fixed stop position. The actuator may further include an adjustment member (60) that engages the electromagnet so as to control the pressure of the electromagnet against the second resilient member, whereby the axial position of the is controlled.

Title: Virtual address translation hardware assist circuit and method
Inventor: OLSON STEPHEN W
IPC: G06F12/10
Filed: 1994-03-24
Granted: 2006-07-18
Abstract: A method, and circuitry that operates in accordance with the method, for generating an entry for a translation buffer in a data processor that employs virtual memory addressing.     The method includes the first steps of storing a Faulted Virtual Address in a first register (96) and a Zone Table Address (ZTA) in a second register (94). In response to the execution of a micro-instruction, a next step forms an address in memory of a Zone Table Entry (ZTE) by selectively combining the content of the first register with the content of the second register, while simultaneously testing the ZTA for physical address mapping. In response to an execution of a next micro-instruction, a next step accesses the ZTE with the formed address, and forms an address in memory of a Segment Table Entry (STE) by selectively combining the content of the first register with a content of the ZTE, while simultaneoysly testing the ZTE for a Zone fault. In response to an execution of a next micro-instruction, a next step accesses the STE with the formed address, and forms an address in memory of a Page Table Entry (PTE) by selectively combining the content of the first register with a content of the STE, while simultaneously testing the STE for a Zone fault. In response to an execution of a next micro-instruction, a next step accesses the PTE with the formed address and selectively combines the content of the STE with the content of the PTE and outputs the combination as a translation buffer entry, while simultaneously testing the PTE for a Page fault.

Abstract: A multi-sensor blending circuit (12) for use in rate responsive cardiac pacemaker. The blending logic circuit (12) blends delta pacing rate signals from two or more sensors (22) which measure physical and physiological parameters of a patient. Programmable equations stored in the blending logic circuit (12) determine which percentages or a ratio of the delta pacing rate sensor signals comprise a single delta pacing rate signal as a function of the delta pacing rate. This delta pacing rate signal is provided to the pacing control circuitry (14) of a pacemaker. The blending ratios are dynamically determined based on the pacing rate established at the most recent cardiac cycle. The blending equations are comprised of several programmable variables, wherein the equations can be programmed by the external programmer (16) in view of clinical data.

Patent CA-2191162-C (CA)
Inventor: WINLOW DAVID SOWDEN
IPC: H03K17/56
Filed: 1996-11-25
Granted: 2005-04-05
Abstract: This circuit provides for a capacitor to be charged to a working level while a small current is allowed to flow through a transistor-resistor circuit which is paralleled with the gate circuitry of a thyristor. Under quiescent operating conditions when the gate circuitry is not energized, only a small current flows in the transistor-resistor circuit. Upon receipt of a turn on signal from the trigger circuit, the gate circuitry is switched on allowing the capacitor to discharge through the gate circuitry into the gate of the load thyristor.      A second transistor connected into the transistor-resistor circuit allows the initial steep pulse to be transmitted to the gate, but the gate current is limited as the second transistor biases the first transistor into a state where only a limited current may pass to the thyristor gate.

Title: Circuit arrangement for operating electric lamps, and an operating method for electric lamps
Inventor: RUDOLPH BERND
IPC: H05B41/292
Filed: 1997-03-25
Granted: 2004-11-09
Abstract: The circuit arrangement according to the invention has a self-oscillating inverter having at least two alternately switching transistors (Q1, Q2), a load circuit connected to the inverter output and designed as a resonant circuit (L1, C1), and terminals for at least one electric lamp (LP). According to the invention, the control junction of a transistor (T1) is arranged in the emitter line of one of the inverter transistors (Q2). Via the variable conductivity of this control junction, the effective emitter resistance of the inverter transistor (Q2) is continuously varied as a function of the voltage drop across one of the resonant circuit components (C1), and the clock frequency of the inverter (Q1, Q2) is thereby increased so far that because of the now stronger detuning with respect to the resonant frequency of the resonant circuit (C1, L1) a reduction in the no-load voltage in the load circuit is achieved.
