Patent number: 10124783Abstract: A method for detecting the location of and isolating a leak in a braking system by simultaneously controlling a direct apply subsystem (DAS) and an isolated apply subsystem (IAS) to enable fluid communication between the IAS and the first circuit; to block fluid communication of the DAS with the first circuit; to enable fluid communication of the DAS with the second circuit; and to block fluid communication of the IAS with the second circuit. A sensed travel of an isolated apply component and a sensed fluid pressure developed by the IAS may be used to determine if the leak is present in the first circuit, while simultaneously using the sensed travel of a direct apply component of the DAS, and a sensed fluid pressure developed by the DAS, to determine if the leak is present in the second circuit.Type: GrantFiled: November 2, 2016Date of Patent: November 13, 2018Assignee: VEONEER NISSIN BRAKE SYSTEMS JAPAN CO.

Patent number: 10125839Abstract: The current invention discloses several methodologies that mitigate shock loading and propensity to resonance in agricultural spray boom structures. These include a near planar linkage for decoupling the boom assembly from the vehicle. This serves to permit further aspects of the invention to: Use the combined mass of the booms and center section as the tuned mass of a tuned mass damper: Act as an enabling part of a boom compliant suspension system to mitigate shock loadings otherwise imposed on the boom system, and: Act as an enabling part of an active boom height and roll control systems to permit the accurate navigation of the boom over undulating terrain. Further aspects include the incorporation of tuned mass dampers in the boom structure and components; and the use of the mass and operation of the boom outboard “breakaway” sections as tuned mass dampers.Type: GrantFiled: October 20, 2016Date of Patent: November 13, 2018Assignee: Specialty Enterprises, LLCInventor: Roy Venton-Walters
