Abstract

A portable steerable borescope has a cable bendable steering section adjacent the viewing head, a servo control mechanism for the actuation cables of the bendable steering section, a joystick for actuating the steering section which is located remotely from the insertion tube and a control module/battery pack containing all the operating functions except for the video display which is a standard JVC portable color video monitor, all of which cooperate to yield a compact and portable industrial video borescope that can be used in remote locations as well as in conventional commercial power environments. Special circuitry has been provided to limit power consumption allowing over one hour remote operation without external power or large, heavy cumbersome batteries.
