Patent number: 7043396Abstract: A method and apparatus for guiding an operator in the alignment of the wheels of an automotive vehicle which has been either modified from a original manufacturer configuration, or for which no previously established alignment settings are known. Initially, the operator identifies known information about the vehicle and selects a desired characteristic of the vehicle for which the vehicle alignment is to be optimized. A set of initial alignment settings are presented to the operator, based upon the selected characteristic for the vehicle, and the vehicle alignment is adjusted thereto. One or more subsequent measurements of the vehicle are acquired. Alignment adjustments to further improve the selected characteristic, identified in response to the vehicle measurements are presented to the operator. The process of alignment adjustment, measurement, and presented adjustments is repeated until an optimal alignment setting for the selected characteristic is reached.Type: GrantFiled: December 19, 2003Date of Patent: May 9, 2006Assignee: Hunter Engineering CompanyInventors: Timothy A.

Patent number: 6612152Abstract: A system for servicing a racing car or other car at a track, other race course, or similar destination employs an open platform for supporting the car by its tires in a horizontal position. The platform supports the car, and is itself supported by a crawler, in a carrier vehicle, for example a truck or trailer, when the carrier vehicle is transporting the car. The crawler and platform are also used to unload and load the car from and into the carrier vehicle. To unload the car at the destination, the crawler, with the platform and car on it, is driven out of the carrier vehicle and onto the ground. Next, the platform is elevated by extending its legs so that it rises off, is spaced from, and straddles the crawler. Then the crawler is driven out from under the platform. Then the platform is lowered to the ground, where it is used as a lift to elevate the car so that its undercarriage may be accessed. The platform may also be used to tune the chassis of the car.Type: GrantFiled: November 30, 2000Date of Patent: September 2, 2003Inventors: James E. Keaton, James L. Kunka, Donald R. Haulsee

Patent number: 6104970Abstract: A crawler vehicle for inspection of the floor of a tank partially filled with a liquid includes telemetry carried by a tether between the vehicle and the remote station for communication of data and control signals between the vehicle and personnel within the station. The vehicle carries a Hall-effect sensor to sense anomalies in a magnetic flux outside the plate resulting from pitting within the plate. An array of ultrasonic transducer probes provides a detailed picture of the defect. A proximity sensor determines the presence of a step abutment between contiguous plates to command for a retraction of the magnet to prevent collision with the step abutment. A pressure sensor measures the depth between the vehicle and a planar surface of the liquid, used as a reference plane, to determine a degree of flatness of the floor and the presence of any settling of the floor.Type: GrantFiled: February 17, 1998Date of Patent: August 15, 2000Assignee: Raytheon CompanyInventors: Karl F.

Patent number: 5379636Abstract: The brakes of a two-axle vehicle are tested by weighing the vehicle and measuring the braking forces for both axles to determine the actual ratio of front axle braking force to total braking force. The deceleration applied to the vehicle is determined from the weight of the vehicle and the applied braking forces. A nominal preferred value of the ratio of front axle braking force to total braking force is calculated from the determined deceleration and the measured weight of the vehicle. The nominal preferred value varies from test to test with both the actual deceleration and the vehicle weight. For each test, upper and lower limits for the acceptability of the actual ratio of front axle braking force to total braking force are set based upon the computed nominal preferred value. These limits move from test to test with the computed nominal preferred value. The nominal preferred value, the movable limits, and the actual ratio are displayed to the user on a CRT screen.Type: GrantFiled: March 11, 1993Date of Patent: January 10, 1995Assignee: Hunter Engineering CompanyInventor: Nicholas J.

Patent number: 5305636Abstract: A plate brake tester for testing the adequacy of the brakes of a vehicle, particularly suited for testing the brakes of multi-axle vehicles, includes weight bearing plates suitably sized to receive thereon wheel/tire assemblies of a vehicle as the vehicle is driven over the plates. The plates have sensors associated therewith for sensing not only the brake force applied by each wheel/tire assembly, but also for directly sensing the dynamic weight of the wheel/tire assembly on each plate during braking. The adequacy of the brakes is determined from the brake force and the directly sensed dynamic weight. At least some of the sensors are preferably dual axis load cells, each dual axis load cell having one output representing vertical force applied to that plate and having a second output representing horizontal force applied to that plate, the horizontal force being the braking force from the wheel/tire assembly disposed on that plate.Type: GrantFiled: February 12, 1993Date of Patent: April 26, 1994Assignee: Hunter Engineering CompanyInventors: Steven C.
