Claim 1

Independent Claim 193 words

A method for guiding a service person in determining vehicle body elevation stance positions relative to the suspension means which supports the body from the wheels or the floor on which the wheels stand, the method comprising: (a) providing electronic means for storing required body elevation positions for a given vehicle relative to the supporting wheels and the corresponding predetermined desired measurement data for the given specific vehicle; (b) calling up from storage the body elevation positions related to a specific given vehicle corresponding to a vehicle presented for inspection; (c) presenting electronically a visual rendering on a display of the specific vehicle called up together with depicted thereon the locations from which to make body elevation position measurements; (d) applying an electronic linear measuring device at each depicted location visually presented on the display; (e) electronically entering each measurement by actuation of said electronic linear measuring device for comparison with said predetermined desired measurement data; and (f) making a comparison between the stored measurements and the entered measurements for indicating whether the measurements are in or out of agreement with the predetermined desired measurement data for the specific vehicle body called up.

Claim 2

Independent Claim 193 words

A method for guiding a service person in determining vehicle body elevation stance positions relative to the suspension means which supports the body from the wheels or the floor on which the wheels stand, the method comprising: (a) providing electronic means for storing required body elevation positions for a given vehicle relative to the supporting wheels and the corresponding predetermined desired measurement data for the given specific vehicle; (b) calling up from storage the body elevation positions related to a specific given vehicle corresponding to a vehicle presented for inspection; (c) presenting electronically a visual rendering on a display of the specific vehicle called up together with depicted thereon the locations from which to make body elevation position measurements; (d) applying an electronic linear measuring device at each depicted location visually presented on the display; (e) electronically entering each measurement by actuation of said electronic linear measuring device for comparison with said predetermined desired measurement data; and (f) making a comparison between the stored measurements and the entered measurements for indicating whether the measurements are in or out of agreement with the predetermined desired measurement data for the specific vehicle body called up.

Claim 3

Dependent Claim 41 words

The method of claim 1 wherein the finding by comparison that a measurement is out of agreement with specifications prompts the service technician to inspect for probable defective parts which are listed on the display for the specific vehicle called up.

Claim 4

Dependent Claim 26 words

The method of claim 1 wherein said body elevation position measurements are taken for determining the suitability for wheel alignment of the vehicle so called up.

Claim 5

Independent Claim 174 words

A method of directing a service person in the entering of electronically obtained measurement data from a specific vehicle into a vehicle alignment apparatus having a console for the purpose of storing vehicle stance measurements for comparison and for directing the determination of vehicle body positions which affect alignment of vehicle wheels, the method comprising: (a) electronically storing illustrations of vehicle body representation and measurement locations; (b) displaying selected illustrations from the storing thereof which are determined to match a vehicle that is presented for wheel alignment; (c) electronically storing vehicle specification tables relating the measurements to alignment specification; (d) prompting the locations for making linear measurements of a vehicle body representation of measurement locations selectively illustrated; (e) electronically entering linear measurement so made into the electronically stored vehicle specification tables for finding correct corresponding alignment specifications; (f) indicating and storing selectively the correct body measured alignment specifications, or an out of specification condition; and (g) using stored correct alignment specifications as the basis for effecting the corresponding wheel alignment of the measured vehicle.

Claim 6

Independent Claim 174 words

A method of directing a service person in the entering of electronically obtained measurement data from a specific vehicle into a vehicle alignment apparatus having a console for the purpose of storing vehicle stance measurements for comparison and for directing the determination of vehicle body positions which affect alignment of vehicle wheels, the method comprising: (a) electronically storing illustrations of vehicle body representation and measurement locations; (b) displaying selected illustrations from the storing thereof which are determined to match a vehicle that is presented for wheel alignment; (c) electronically storing vehicle specification tables relating the measurements to alignment specification; (d) prompting the locations for making linear measurements of a vehicle body representation of measurement locations selectively illustrated; (e) electronically entering linear measurement so made into the electronically stored vehicle specification tables for finding correct corresponding alignment specifications; (f) indicating and storing selectively the correct body measured alignment specifications, or an out of specification condition; and (g) using stored correct alignment specifications as the basis for effecting the corresponding wheel alignment of the measured vehicle.

Claim 7

Dependent Claim 192 words

Apparatus for use in inspecting and determining vehicle body elevational positions relative to the suspension means which supports a vehicle body from the wheels on the floor on which the wheels rest, the apparatus comprising: (a) wheel alignment console means having a storage memory to receive and make available to a service person alignment data for a series of predetermined vehicles, said memory receiving data on vehicle elevational information and location of points for measuring elevation; (b) means at said console for selecting a predetermined vehicle alignment data and elevational information corresponding to a vehicle presented for inspection and determination of body elevation positions; (c) means in said console means for displaying a representation of portions of the vehicle presented for inspection, said display means presenting at least one location for initial inspection; (d) a linear measuring device which electronically transfers measurements into said console means for making said inspection measurement at said displayed location; (e) circuits in said measuring device and comprising a shaft encoder for entering into said console the completed linear measured value for visual display; and (f) indicating selectively correct alignment specifications, or an out of specification condition.

Claim 8

Dependent Claim 192 words

Apparatus for use in inspecting and determining vehicle body elevational positions relative to the suspension means which supports a vehicle body from the wheels on the floor on which the wheels rest, the apparatus comprising: (a) wheel alignment console means having a storage memory to receive and make available to a service person alignment data for a series of predetermined vehicles, said memory receiving data on vehicle elevational information and location of points for measuring elevation; (b) means at said console for selecting a predetermined vehicle alignment data and elevational information corresponding to a vehicle presented for inspection and determination of body elevation positions; (c) means in said console means for displaying a representation of portions of the vehicle presented for inspection, said display means presenting at least one location for initial inspection; (d) a linear measuring device which electronically transfers measurements into said console means for making said inspection measurement at said displayed location; (e) circuits in said measuring device and comprising a shaft encoder for entering into said console the completed linear measured value for visual display; and (f) indicating selectively correct alignment specifications, or an out of specification condition.

Claim 9

Dependent Claim 37 words

The apparatus set forth in claim 5 wherein said shaft encoder is responsive to means engaging a retractable tape which is extracted from a housing of the measuring device to the indicated length by the service person.
