Granted: 1998-07-07
Abstract: An endocardial lead having first and second spaced apart electrodes resides in a patient's heart.  The first electrode is a sensing electrode and the second electrode is a carrier signal driving electrode.  The lead has a conductor coupling a source of alternating current carrier signals of a predetermined frequency to the second electrode.  A third electrode is in electrical contact with body tissues.  A cardiac pacer apparatus includes a pacer can which functions as a fourth electrode and has a plastic top wherein the third electrode is located.   Said third electrode acts in cooperation with the first electrode to form a pair of sensing electrodes.  The sensing electrode pair is further coupled to a sense amplifier for receiving an amplifying modulated electrical signals developed across the sensing electrode pair.  A demodulator and filters circuit for demodulating the modulated carrier signal and recovering the modulating signal therefrom is connected to the output  of  the  sense  amplifier.    The  modulating  signal  is proportional to instantaneous stroke volume of the patient's heart and the demodulator and filters circuit develops a control signal therefrom called a stroke volume signal.  The control signal is applied to the pulse generator so as to control the rate of stimulating pulses.

Title: Computer generated cavity length control with automatic gain control for laser gyros
Inventor: MARK JOHN G
IPC: G01C19/66
Filed: 1991-08-02
Granted: 1995-12-19
Abstract: A ring laser gyro having a ring laser that preferably has four legs and four corner mirrors.  At least one of the corner mirror is partly transmissive, and the transmitted beam is sensed and converted into a digital signal.  The digital signal is fed back in two computer loops to at least one digital-to-analog converter, and thence to a transducer which drives at least one corner mirror inward and outward. One of the computer loops includes a stepped demodulator having four steps per cycle.  The steps have voltages at the operating voltage of the transducer, that voltage plus an increment, the operating voltage, and that voltage less a decrement.  The first loop sends an operating voltage to the digital-to-analog converters.  The second loops demodulates the beam signal at a second harmonic of the demodulation of the first loop to produce a voltage signal which controls-the amplitude of dithering of the movable mirrors.  A stepped modulator, in synchronism with the demodulator of the first loop, delivers a modulation signal to the digital-to-analog converters to step the movable mirrors.  The operating voltage moves the mirrors into a position wherein the laser cavity operates at its intensity mode peaks.
