Patent number: 6220676Abstract: According to one aspect of the invention, a brake controller is provided for controlling an amount of braking force applied to a plurality of wheels of a vehicle running on a surface. Each of the plurality of wheels has a sensor for providing an output signal indicative of a corresponding speed of the wheel.

Patent number: 5979042Abstract: A printed wiring assembly rework tool and method which eliminates the need to remove a component from the printed wiring assembly in order to isolate a component pin from one or more printed circuits in the printed wiring assembly. The rework tool is able to mill or cut away a plated through hole and/or the area of the printed wiring assembly immediately surrounding the component pin without removing the component. Using the rework tool, the operation continues until the rework tool has either cut to a sufficient depth in the printed wiring assembly to sever a particular electrical connection, or the tool has cut all the way through the printed wiring assembly in order to completely isolate the component pin. The rework tool includes a pilot hole which accommodates the component pin as the tool cuts into the printed wiring assembly.Type: GrantFiled: March 10, 1997Date of Patent: November 9, 1999Assignee: Simmonds Precision Products, Inc.Inventor: Alan Moss Duke

Patent number: 5951122Abstract: A brake control system which employs an antiskid control and wheel lock protection differential reference controller to provide antiskid and antilock brake control. The differential reference controller is capable of estimating both wheel velocity and vehicle velocity based on a single wheel speed sensor input. To reduce the effects of wheel speed noise, the differential reference controller estimates the wheel velocity and vehicle velocity by carrying out parallel processes using identical processing functions. The estimated wheel velocity and vehicle velocity are subtracted providing a differential output indicative of the slip velocity. Only unique parameters for each process, derived from physical constants, are different. In this way, the wheel speed noise is introduced into both processes and canceled when the results are subtracted to obtain the slip velocity.Type: GrantFiled: December 31, 1997Date of Patent: September 14, 1999Assignee: The B.F. Goodrich CompanyInventor: John T. Murphy
