Publication number: 20190113035Abstract: The present teachings include an energy recovery device usable in multiple applications, for example hydropower and vehicle power plant applications. In one aspect, an energy recovery device includes a housing having an inlet and an outlet in fluid communication with an internal cavity, and a pair of counter-rotating rotors having intermeshed lobes disposed within the housing internal cavity. Each rotor defines a transport volume between the housing and a pair of adjacent lobes and has a calculated maximum ideal twist angle below which the transport volume will be sealed from both the housing inlet and housing outlet. Each rotor also has an actual twist angle that exceeds the maximum ideal twist angle.Type: ApplicationFiled: March 9, 2017Publication date: April 18, 2019Inventors: Matthew Gareld SWARTZLANDER, David YEE

Patent number: 8468803Abstract: A soot resistant and efficient diesel fuel reformer for a diesel exhaust aftertreatment system has serially arranged first and second catalyst supports. The first support is nearer the inlet and has a monolith structure that is uniform in the direction of flow. The second support has a modified monolith structure that is non-uniform in the direction of flow. Preferably, the first support has straight channels. Preferably, the second support has internal leading edges spaced periodically through its length to break up the flow. The first support has a catalyst coating comprising at least an oxidation catalyst. The second support has a catalyst coating comprising at least a steam reforming catalyst.Type: GrantFiled: February 26, 2011Date of Patent: June 25, 2013Assignee: International Engine Intellectual Property Company, LLCInventors: Bret Robert Armanini, Jacques F.

Patent number: 8209960Abstract: A diesel exhaust aftertreatment system comprises an LNT within an exhaust line. A low thermal mass DPF and a low thermal mass fuel reformer are configured within the exhaust line upstream from the LNT. A thermal mass is configured downstream from the fuel reformer and the DPF, but upstream from the LNT. For LNT denitration, the fuel reformer is rapidly heated and then used to catalyze steam reforming. The DPF is also rapidly heat each time the fuel reformer is heated and the LNT denitrated. The system operates to regenerate the DPF each time the LNT is denitrated. Preferably, a second DPF is provided to augment the performance of the first DPF. Preferably, the first DPF is small and of the flow through type whereas the second DPF is much larger and of the wall flow filter type. The second DPF can be used as the thermal mass.Type: GrantFiled: December 7, 2009Date of Patent: July 3, 2012Assignee: International Engine Intellectual Property Company, LLCInventors: Dmitry Arie Shamis, James Edward McCarthy, Jr., Jiyang Yan, David Yee

Patent number: 8073930Abstract: The present invention provides an assistive technology screen reader in a distributed network computer system. The screen reader, on a server computer system, receives display information output from one or more applications. The screen reader converts the text and symbolic content of the display information into a performant format for transmission across a network. The screen reader, on a client computer system, receives the performant format. The received performant format is converted to a device type file, by the screen reader. The screen reader then presents the device type file to a device driver, for output to a speaker, braille reader, or the like.Type: GrantFiled: June 14, 2002Date of Patent: December 6, 2011Assignee: Oracle International CorporationInventor: David Yee

Patent number: 7975489Abstract: According to one aspect, a method of detecting catalyst module overheating in a catalytic combustion system is provided. In one example, the method includes detecting one or more signals from at least one probe adapted to obtain values associated with at least one of the outlet gas temperature of a catalyst module and the outlet face temperature of the catalyst module included in a catalytic combustor. The one or more signals are compared with a preselected value associated with catalyst overheating. The detected temperature may be detected over time to determine a rate of change in the temperature. The temperature may be detected with a UV sensor directed to the catalyst outlet face.Type: GrantFiled: September 1, 2004Date of Patent: July 12, 2011Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Ajay Joshi, David Yee

Patent number: 7693732Abstract: The present invention provides a computer implemented lab reservation system including a reservation engine and a reservation database. The reservation database contains data concerning the computer systems and target operating environments in the lab. The reservation engine manipulates the reservation database in order to efficiently match user requests to specific lab computer systems and target operating environments. The reservation system also manipulates the reservation database in order to efficiently configure computer systems and target operating environments. The reservation engine also manipulates the reservation database in order to efficiently reinstall computer system default settings, when users return configured systems, so that the computer systems can be reallocated to new requests.Type: GrantFiled: June 25, 2002Date of Patent: April 6, 2010Assignee: Oracle International CorporationInventors: Stefano Cei, Gregory Collins, Krishna Nekkalapudi, Ranga Polisetti, Daryl Porter, David Yee
