Abstract: A comparator is disclosed for examining, inspecting and/or calibrating component parts. The comparator includes a frame, a component supporting system releasably attached to the frame for supporting a component part to be inspected and/or calibrated, a video imaging system attached to the frame for generating a video image of the component part on a video display, a graphic line image generator for superimposing on a video display graphic images arranged to display and represent predetermined dimensional ranges related to the component part, whereby the component part may be compared to the predetermined images of the graphic images.

Abstract: The present invention relates to a machine actuating system, which includes a hand actuator system which responds to the presence of at least one operator body part at a predetermined location by generating control signal and an actuator control system to actuate the machine in response to the control signal. Generally, the actuating system includes a pair of ergonomic support members, where one support member is configured and dimensioned for interactive association with the operator's left hand and the other support member is configured and dimensioned for interactive association with the operator's right hand, and a sensing system associated with each support member for sensing the presence of the operator's hands and generating the control signal.
