Abstract: A vehicle wheel alignment sensor for a machine-vision vehicle wheel alignment system comprising a scanned beam camera incorporating an illumination source, a means for deflecting light emitted by the illumination source along a path within a field of view, and a detector array for receiving illumination reflected from objects within the field of view to generate an image which is representative of a region of interest within the field of view.

Abstract: An improved computer controlled optical imaging vehicle wheel alignment system configured to obtain one or more color images of optical targets associated with a vehicle, and to process the color images to obtain vehicle wheel alignment measurements.

Abstract: A method for the operation of a vehicle wheel service system configured to illuminate a surface of a vehicle wheel rim and tire assembly. The method includes the steps of mounting a vehicle wheel rim and tire assembly onto the vehicle wheel service system, coating a surface of the vehicle wheel rim and tire assembly with a medium to alter the optical characteristics of the vehicle wheel rim and tire assembly surface, and illuminating the optically altered surface of the vehicle wheel rim and tire assembly.

Abstract: A machine vision vehicle wheel alignment system optical target assembly incorporating an adaptor for attachment of an optical target to a vehicle wheel assembly. The adaptor includes at least three contact points for abutment against surfaces of a vehicle wheel assembly, and an attachment mechanism configured to grip surfaces of a tire mounted to the wheel rim to hold the optical target assembly in contact with the wheel assembly surface. The optical target is secured to the adaptor, and maintained in a fixed relationship to the wheel assembly thereby during a vehicle wheel alignment measurement procedure.

Abstract: A method of the present invention provides methods for processing images of vehicle wheel assemblies acquired during vehicle service procedures to determine vehicle wheel assembly pose components, from which vehicle wheel alignment angles may be calculated.

Abstract: A camera configuration for a machine vision vehicle wheel alignment system which does not dispose all of the cameras on a single rigid structure, such that cameras disposed to view the left side of a vehicle are movable independently of the cameras disposed to view the right side of the vehicle, while maintaining a common reference coordinate system for determining vehicle wheel alignment angles.

Abstract: A vehicle wheel alignment system utilizing a non-contact range finding system in conjunction with one or more optical imaging sensors to acquire images of a fixed target, fixed random object, or the vehicle wheels, from which three-dimensional information related to one or more optical imaging sensor positions or vehicle wheel alignment angles can be obtained.

Abstract: A machine vision system is configured to facilitate placement of a vehicle service apparatus relative to an associated vehicle. The machine vision system is configured to utilize images of optical targets received from one or more cameras to guide the placement of the vehicle service apparatus relative to the associated vehicle.

Abstract: A system for monitoring motion includes a cable-encoder combination to create an electrical signal indicating distance and a microprocessor monitoring system to provide time measurement in conjunction with distance information and to provide alarms whenever predetermined limits are exceeded. The system provides a teaching mode for teaching the predetermined limits, and provides a velocity adaptive mode in which a certain informational values may be adjusted over fixed time periods to provide for moving references.

Abstract: A computerized electro-oculographic (CEOG) system comprises an integrated system for automated administration of electro-oculographic tests and visual evoked response tests to a patient, and automated processing of the results derived from such tests. The CEOG system is responsive to operator selection of desired stimuli to be administered, as well as to operator specification of various test stimuli characteristics, for automatically administering to the patient the test stimuli having the desired characteristics. Electrode test data derived therefrom are immediately recorded on-line, and are immediately and automatically analyzed to provide critical information for immediate display in acceptable format and in a very short period of time. The integrated CEOG system compensates for the "offset voltage" phenomenon typically encountered with respect to electrode test data by provision of both manual and automated compensating capabilities.
