Patent number: 11008028Abstract: An assembly that includes a housing with a chamber formed within a bore of the housing. The assembly further includes a center shaft disposed at least partially within the bore of the housing. The chamber includes a backing wedge, a sliding wedge, and a load spring. The sliding wedge is positioned to apply a force onto an angled contact surface of the backing wedge. The sliding wedge is also positioned to apply a frictional force to a rod portion of the center shaft. The load spring is compressed between a contact surface of the chamber and a contact surface of the sliding wedge. The load spring is positioned to apply a compressive force onto the contact surface of sliding wedge toward the angled contact surface of the backing wedge.Type: GrantFiled: February 21, 2018Date of Patent: May 18, 2021Assignee: TRINITY RAIL GROUP, LLCInventor: Shaun Richmond

Patent number: 10389036Abstract: A ground penetration radar (GPR) antenna system is integrated into a digging machine such that the system is configured to remain operable under the same environmental conditions as the machine. The system includes an RF antenna and an antenna monitor. The antenna includes a rectangular hollow enclosure made of a conductive material defining a cavity therein and is affixed to a bucket of the digging machine. The antenna monitor is rigidly connected to the hollow enclosure and monitors inertial antenna location and/or movement.Type: GrantFiled: January 18, 2018Date of Patent: August 20, 2019Assignee: RODRADAR Ltd.Inventors: John Francis Roulston, Ely Levine, Haim Matzner

Patent number: 10124800Abstract: Method and apparatus for providing autonomous control of a vehicle. A vehicle can be manually controlled by an operator. An autonomous system can monitor the operator's control inputs and the environment of the vehicle to determine whether the control inputs result in safe operation of the vehicle. If control inputs are not safe, then the autonomous system can modify the operator's unsafe inputs into safe inputs. In various instances, the autonomous system can operate the vehicle without operator input. In the event an operator attempts to apply control inputs to the vehicle while the autonomous system is otherwise in control, the autonomous system can check to see whether the operator's inputs result in safe operation of the vehicle. If the operator's control inputs are safe, then the autonomous system can replace its autonomous commands with the operator's commands.Type: GrantFiled: May 30, 2014Date of Patent: November 13, 2018Assignee: THE BOEING COMPANYInventors: Richard Donovan Jones, David A. Whelan, Lynne Wenberg

Patent number: 9361797Abstract: Systems, methods, and apparatuses are disclosed for identifying anomalies or changes in road conditions on a roadway location. An initial low rank data matrix of initial vehicle probe data at a plurality of different times for a roadway location is provided, where the initial low rank data matrix represents a baseline of road conditions for the roadway location. A plurality of additional vehicle probe data from at least one vehicle at the roadway location is received. The additional vehicle probe data is added to the initial vehicle probe data of the initial low rank data matrix. The updated data matrix with the compiled probe data is decomposed into a low rank data matrix and a sparse data matrix. A change at the roadway location is identified based on the probe data in the sparse data matrix.Type: GrantFiled: December 11, 2014Date of Patent: June 7, 2016Assignee: HERE Global B.V.Inventors: Xin Chen, Vladimir Zhukov

Patent number: 6768944Abstract: Control system and method for controlling a vehicle or a component of a vehicle in which an inertial reference unit includes accelerometers and gyroscopes which provide data on vehicle motion and a processor processes the data and controls the vehicle or the component of the vehicle based thereon. Movement of the vehicle may be controlled via control over servos, such as a servo associated with the braking system, a servo associated with the drive train or throttle and a servo associated with the steering system. A display to the driver can also be controlled by the processor to provide data on vehicle motion or data or information derived from the data on vehicle motion. Optionally, a Kalman filter is coupled to the processor for optimizing the data on vehicle motion from the inertial reference unit.Type: GrantFiled: August 9, 2002Date of Patent: July 27, 2004Assignee: Intelligent Technologies International, Inc.Inventors: David S. Breed, Wendell C. Johnson, Wilbur E. DuVall

Patent number: 5501347Abstract: A draft gear assembly having a variable angle friction clutch mechanism is provided. Such assembly includes a housing member having a compressible cushioning element disposed adjacent a closed end thereof. A seat is disposed between one end of the compressible cushioning element and an open end of the housing member. A friction cushioning mechasim is positioned at least partially within the open end of the housing member and includes a plurality of friction surfaces disposed on a plurality of friction elements with at least one wedge member being engageable with the plurality of friction surfaces. At least one resilient member is provided to enable the friction cushioning mechanism to exhibit a variable angle. Such resilient member is engageable with at least one of the friction elements and exerts a lateral force on the friction cushioning mechanism which is at least sufficient to maintain all of the friction surfaces in frictional engagement during the useful life of the draft gear assembly.Type: GrantFiled: April 5, 1995Date of Patent: March 26, 1996Assignee: Westinghouse Air Brake CompanyInventors: Walter H. Merker, Jr., Howard R. Sommerfeld
