Patent Images
1. An automotive test equipment parameter input system comprising:
- display means for visually displaying a potential value of a parameter for automotive test equipment;
manually operable rotary input means operable by a user for providing, by rotation of said input means, an indication that a change in the displayed value is desired by the user; and
electronic means, connected to the display means and responsive to the indication from the input means that a change is desired, for controlling the display means to change the potential value of the parameter displayed by the display means in accordance with the rotation of the rotary input means;
wherein the manually operable rotary input means is operable by the user applying variable pressure thereto, said input means providing a variable signal to the electronic means, said variable signal varying in accordance with the amount of pressure applied by the user, said electronic means controlling the display means to change the displayed value at a rate corresponding to the pressure applied by the user to the manually operable rotary input means.

Abstract
A manual parameter input system for automotive test equipment such as a vehicle wheel balancer. Variable pressure input knobs supply rotation direction and "applied pressure" information to the balancer'"'"'s internal computer. The computer updates the value displayed by digital visual displays at a rate corresponding to the applied pressure to the knob. The visual display output is independent of the actual rotational position of the input knobs, and hence is highly tolerant of mechanical slippage and other mechanical deficiencies in the input system.
