Retractable Cover for Automobile Service Pit with Oil Change Mechanism, Detent Pin and Method of Use
Publication number: 20250129629Abstract: A retractable cover for an automotive service pit allowing an auto technician to utilize a retractable cover and mobile oil drain attachment to successfully collect oil from an automotive oil pan as well as provide repair and replacement of vehicle parts while providing a protective cover over an open automotive pit. Too, the present invention allows for a quick release mechanism, in the form of a detent pin, internal or external to said service pit, which allows an automotive technician to quickly and easily release the present pit cover when in need of a rapid service pit cover release for service person's entrance or egress.Type: ApplicationFiled: October 6, 2022Publication date: April 24, 2025Inventors: Ben Keith Rice, Sr., Benjamin Keith Rice, Jr., Janise L.

Patent number: 9896223Abstract: A pump system for controlling a pressure load delivered to an aircraft interface included in the pump system is disclosed. The pump system includes a pump circuit, a pump, and a valve system. The pump is coupled with the conduits and is configured to provide a pressure load to the aircraft interface to move fuel from a fuel reservoir through the conduits toward the aircraft interface in a fueling mode and to move fuel from the aircraft interface through the conduits toward the fuel reservoir in a defueling mode. The valve system is coupled to the conduits and configured to control the pressure load delivered to the aircraft interface to block the pressure load from exceeding either of a high-pressure threshold and a delta-pressure threshold.Type: GrantFiled: December 15, 2015Date of Patent: February 20, 2018Assignee: Wabash National, L.P.Inventors: Keith Rice, Sean Quinn, George R. Larkin, Martin Pelkey

Patent number: 8818515Abstract: Methods and systems for delivering voltage limited neurostimulation to a patient. In one aspect, a method includes initiating a flow of electrical current through a first electrode and a second electrode coupled to the patient and increasing the flow of electrical current toward a target value by increasing a voltage across the first electrode and second electrode. Prior to reaching the target value of electrical current, the method includes preventing the voltage across the first electrode and second electrode from increasing beyond a first predetermined limit; and subsequently, maintaining the voltage across the first electrode and second electrode at or within a predetermined range that does not exceed the first predetermined limit. The amplitude of the electrical current continues to increase toward the target value during at least part of a time when the voltage across the first electrode and the second electrode is maintained within the predetermined range.Type: GrantFiled: January 13, 2012Date of Patent: August 26, 2014Assignee: Research Foundation of the City University of New YorkInventors: Marom Bikson, Christoph Hahn, Shiraz A. Macuff, Preet Minhas, Asif Rahman, Justin Keith Rice

Patent number: 7757508Abstract: A heat pump has a refrigerant loop, a compressor in fluid communication with the refrigerant loop, at least one indoor heat exchanger in fluid communication with the refrigerant loop, and at least one outdoor heat exchanger in fluid communication with the refrigerant loop. The at least one outdoor heat exchanger has a phase change material in thermal communication with the refrigerant loop and in fluid communication with an outdoor environment. Other systems, devices, and methods are described.Type: GrantFiled: August 31, 2005Date of Patent: July 20, 2010Assignee: UT-Battelle, LLCInventors: Moonis Raza Ally, John Jager Tomlinson, Clifford Keith Rice

Patent number: 7337994Abstract: Rope made of cellulose fibers, the polymeric chemical structure of which fibers has not been modified (referred to as “raw” cellulose fibers), are subjected to intense electron beam irradiation insufficient to degrade their chemical structure but sufficient to modify their physical structure so as to allow them to be comminuted into fragments having a length no more than 6.35 mm (0.25?), preferably less than 3.175 mm (0.125?), and preferably 50% by weight of the fibers have a length less than 70 ?m. Such fragments of fibers are found to be particularly susceptible to being micronized in a micronizer into elongated granular fragments smaller than about 20 ?m at an economical production rate in excess of 22.7 Kg/hr (50 lb/hr) which was not possible when the micronizer was fed with naturally occurring fibers.Type: GrantFiled: January 14, 2004Date of Patent: March 4, 2008Assignee: React-NTI, LLCInventors: Bruce Anthony Tavares, Frederick Emmett Coffey, Dennis Keith Rice

Publication number: 20070005690Abstract: Video and audio signals are streamed to remote viewers that are connected to a communication network. A host server receives an originating video and audio signal that may arrive from a single source or from a plurality of independent sources. The host server provides any combination of the originating video and audio signals to viewers connected to a communication network. A viewer requests the host server provide a combination of video and audio signals from the host server. The host server transmits an instruction set to be executed by the viewer. The instruction set causes the viewer to transmit parameters to the host user, including parameters relating to the processing capabilities of the viewer. The host server then transmits multimedia data to the viewer according to the received parameters. A plurality of viewers may be simultaneously connected to the host server.Type: ApplicationFiled: September 1, 2006Publication date: January 4, 2007Inventors: Janine Corley, Jeffrey Davey, Bruce Johnson, Dale Johnson, Christopher Lund, Tien Nguyen, Keith Rice, Leonid Volfson
