Abstract: A gyro motor drive speed control system using reference coils in place of turable reactors for motor start up and spin direction. An oscillator provides a 1 H.sub.z squarewave signal to rotate the motor magnet in some direction, and movement of the magnet causes a magnetic field disturbance which induces a current into the reference coils. The signals from the reference coils are fed back into the oscillator and through a phase shifting and squaring network, with one reference signal shifted 90.degree. out of phase. The multiplied output signals are fed into a circuit for motor drive and speed control. If the magnet begins to spin in the wrong direction, the quadratured lead-lag signals will be reversed, acting against the magnet, causing it to stop and reverse direction.

Abstract: This invention pertains to blemish compensation circuits and particularly blemish compensation circuits for Charge Coupled Device cameras.

Abstract: An analog video processor is disclosed for coupling a CCD target acquisition and tracking seeker to a microcomputer via a video preprocessor, having a CCD automatic light control circuit, a video automatic gain control circuit, and a TV monitor/display circuit, and via a video processor, having a target acquisition mode gradient processor circuit, to detect target edge sharpness, a target tracking mode contrast processor circuit to detect targets via video amplitude, and an output control circuit, to convert analog and asynchronous target signatures to synchronous target edges for input to the microcomputer.
