Patent number: 11524683Abstract: Industrial vehicles that include a speed sensor configured to generate a speed sensor signal, a payload sensor configured to generate a payload sensor signal, an inclination sensor configured to generate an inclination sensor signal, a wheel motor connected to a wheel of the industrial vehicle, and a controller. The wheel motor includes an electric retarder device for applying a retardation force to the wheel. The controller is configured to receive the speed sensor signal, receive the payload sensor signal, receive the inclination sensor signal, determine a required retardation force for the industrial vehicle based on the payload sensor signal and the inclination sensor signal, determine an available retardation force for the industrial vehicle based on the speed sensor signal, and generate an output indicating the required retardation force for the industrial vehicle relative to the available retardation force for the industrial vehicle.Type: GrantFiled: February 12, 2020Date of Patent: December 13, 2022Assignee: KOMATSU AMERICA CORP.Inventors: David J. Scott, Sudhir Reddy Thaduru

Publication number: 20220280337Abstract: Methods and apparatuses for temperature modification of a patient, or selected regions thereof, including an induced state of hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette is attached to the circulatory conduits of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. The control unit includes a heater/cooler device for providing heated or cooled fluid to a heat exchanger in thermal communication with the fluid heat exchange medium circulating to the heat exchange catheter, a user input device, and a processor connected to receive input from various sensors around the body and the system. A temperature control scheme for ramping the body temperature up or down without overshoot is provided.Type: ApplicationFiled: March 22, 2022Publication date: September 8, 2022Inventors: David J. Scott, Ben F. Brian, Lloyd F. Wright, Leo A. Chin, Edward W. Hollmen, Daniel W. Seegars, Mark A. Logan

Patent number: 11034572Abstract: A vehicle or machine may include a consumable that requires refilling, such as fuel. Refilling the consumable may occur at a regular interval and the amounts may be recorded. Based on the past intervals and amounts, there may be modifications to future amounts. The weight of the consumable on a vehicle may decrease efficiency. Accordingly, the amount of consumable should be kept to a minimum to avoid carrying excess weight. Reducing an amount of the consumable upon replenishment can improve efficiency of the vehicle.Type: GrantFiled: August 19, 2019Date of Patent: June 15, 2021Assignee: Komatsu America Corp.Inventor: David J. Scott

Patent number: 10219902Abstract: Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the left atrium, which allow mitral valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial adjustability and retrievability years after implant. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant and a fixed length implant. The implants or systems of implants and methods may also utilize an adjustable bridge stop to secure the implant, and the methods of implantation employ various tools.Type: GrantFiled: February 13, 2017Date of Patent: March 5, 2019Assignee: MVRx, Inc.Inventors: Timothy R.

Patent number: 9708957Abstract: The heat provided to a vehicle based SCR system may be managed by purposely increasing the load placed on the vehicle's engine such that the engine's exhaust gas temperature remains above a predetermined level. The energy generated by the extra load placed on the engine may be dissipated through an energy absorption device. The need for extra engine load may be anticipated to ensure adequate heat is provided to the SCR throughout various operating conditions.Type: GrantFiled: August 16, 2016Date of Patent: July 18, 2017Assignee: Komatsu America Corp.Inventor: David J.
