Title: Power control system for an a.c. induction motor
Inventor: ANDERSON NICHOLAS
IPC: H02J3/18
Filed: 1993-12-14
Abstract: A power factor control system (100) for an A.C. induction motor (106) determines the difference in phase between the voltage applied to the motor (106) and the current drawn by the motor (106). Based upon this difference in phase, an integrator (178) generates an error signal. The error signal is compared with a ramp wave to derive a pulse signal which controls the voltage applied to the motor (106), which in turn controls the amount of current supplied to the motor (106), in order to reduce the power consumed by the motor (106). The integrator (178) includes a dual-path feedback filter (192) having a polarized capacitor in each path. A power supply (110) is used to quickly provide the full operating bias voltages required by several of the operating bias contained in the control system (100).

Inventor: COOKSON CHRISTOPHER J
IPC: G11B19/04
Filed: 1994-10-13
Abstract: A system using an optical disk format for representing several synchronized signals, e.g. multiple versions of motion pictures and multiple soundtracks which is made up of an optical disk (23), signal processors (67, 71), buffer circuitry (53, 55, 57, 59) and audio (91) and video (94) output devices. All signals are represented digitally, and the bits are arranged in data blocks. Each data block may contain a variable number of bits for each signal, ranging from none to many (relative to the other signals). This allows each signal to be represented by a variable rate bit stream, without one signal necessarily constraining another as far as bit representation is concerned. Multiple buffers are provided to insure that there are a sufficient number of bits available for each signal as required for immediate needs. When any buffer is full, reading of the data blocks stops temporarily so that no bits are lost.
