Patent CA-2189851-A1 (CA)
Inventor: MUTERSPAUGH MAX WARD
IPC: G05F1/573
Filed: 1994-09-13
Abstract: The present invention concerns a voltage regulator wherein the series pass transistor and an amplification transistor are of complementary types. Supply current flows from the DC supply source through the emitter-collector path of the series pass transistor to the load. The amount of this current is controlled by a negative feedback control signal coupled from the regulated output voltage to the base electrode of the amplification transistor, which in turn drives the base of the series pass transistor. The emitter electrode of the amplification transistor is coupled to a voltage which is less than the regulated DC output voltage so that drive requirements for the pair of transistors is reduced.

Patent CA-2229815-A1 (CA)
Inventor: MENICH BARRY J
IPC: H04B7/005
Filed: 1997-03-27
Abstract: Power control in a spread-spectrum communication system takes place by determining origination power of a traffic channel based on a number of active demodulators and pilot channel signal quality (610). Once origination transmit power is determined and call origination takes place, the transmit power is reduced at a first rate when a time is less than a time for all active demodulators to be established (615), otherwise the transmit power is reduced at a second rate (621). After all active demodulators have been acquired power control takes place by receiving a Power Measurement Report Message (PMRM) or a Pilot Strength Measurement Message (PSMM), determining a signal quality metric existing at the remote unit based on the PMRM or PSMM, and adjusting transmit power based on the signal quality metric (645).
