Abstract: A control handle and viewing screen assembly combines video monitor and remote steering control for a borescope steering section. A joystick or similar device controls the steering section when an inspection mode is employed. In a second or freeze-frame mode the joystick is used to move a cursor on the screen or to carry out a computation function. Steering servo motors can be positioned distally for balance.

Abstract: A light chopper wheel for use in a video system that is capable of producing either black and white or full color images. The wheel is formed of two circular sheet metal plates that are joined in back-to-back contact. A first series of circumferentially spaced color filter windows are located about a first diameter on the wheel and a second series of clear windows are circumferentially spaced about a second diameter on the wheel so that a clear window is radially adjacent each color filter window. Recesses are stamped in the back of each plate behind each color filter window and filters are mounted between the plates within the recesses.
