Abstract: A vehicle alignment system for inspecting and adjusting alignment of the suspension of numerous different vehicle models includes manually operable switches for selecting a particular vehicle model, a CD-ROM for storing a number of digital photographs depicting actual wear and adjustment points of different actual vehicle models, a display for displaying digital photographs, and a controller which responds to the selection of a particular vehicle model for providing, if available, at least one of the stored digital photographs for that particular vehicle model to the display for display.

Abstract: Electronic measuring gauge and apparatus therefor comprising in combination apparatus and method for use in inspecting and determining vehicle body elevational position relative to the suspension which supports the vehicle body from the wheels or the floor on which the wheels rest. Components are provided to store and present alignment and body elevation measurement points for subsequent call up to suit a specific vehicle presented for inspection and a measuring device for finding the measurements at the measurement points. The apparatus and the method of its use increases the accuracy of inspection and reduces the time required to perform the linear measurements to assist in vehicle wheel alignment operations.

Abstract: A vehicle wheel turning angle gauge having a base to support a wheel engaging turnable plate which supports an optical encoder device mounted in non-rotary position so an operating shaft can engage and turn with the turnable plate to generate signals of the degree of turn and the direction of that turn. The base provides a structure for limiting the maximum displacement of the turnable plate without restricting its direction of motion so it will accommodate the range of vehicle wheel movement as required for alignment purposes.
