Publication number: 20150261551Abstract: Simulation of execution of a processing workload by a target hardware device is provided by providing workload data specifying the processing workload, passing the workload data to both a primary partial simulation and a complementary partial simulation that run in parallel and acquire input data from different levels of abstraction of the target hardware and then simulating execution of the processing workload using a primary partial simulation to generate primary partial result state data and using the complementary partial simulation to generate complementary partial result state data. The target hardware device may be a graphics processing unit and the workload data may specify the processing to be performed in a hardware independent form, such as, for example, OpenGL ES. The host system supporting the simulation may include a graphics processing unit serving to provide the complementary partial simulation due to its own execution of the workload data.Type: ApplicationFiled: February 11, 2015Publication date: September 17, 2015Inventors: Robert James CATHERALL, Anthony Neil BERENT, Rhys David COPELAND, Mark EDGEWORTH, Jonathan Stephen BLACK

Patent number: 8660813Abstract: Illustrative embodiments of the present invention are directed to a method and system for disaggregating climate control energy use from non-climate control energy use for a building. The method includes receiving a series of building energy use values and corresponding outdoor temperature values for a time period. Each of the energy use values and outdoor temperature values is associated with a time interval. The method further includes determining a series of temperature difference values for the time period based on a difference in temperature between a predetermined baseline temperature and each of the outdoor temperature values. A regression analysis is used to determine a climate control coefficient and a non-climate control coefficient from the energy use values and temperature difference values. The climate control coefficient and/or the non-climate control coefficient is used to determine climate control energy use and/or non-climate control energy use for the building.Type: GrantFiled: November 5, 2010Date of Patent: February 25, 2014Assignee: OPOWER, Inc.Inventors: Richard Curtis, David Copeland, Daniel J.

Publication number: 20110035589Abstract: A trusted content usage monitor for monitoring content usage is provided. A unique identifier generation unit generates a unique identifier indicative of content being rendered and a packet generator generates a trusted packet comprising the unique identifier. The trusted packet is trust signed by the trusted content usage monitor, so that it can be trusted by its recipient. The trusted content usage monitor has at least one mode of operation in which content rendering cannot be decoupled from operation of the unique identifier generation unit, so that generated packets can be trusted as truly indicative of content usage.Type: ApplicationFiled: August 10, 2009Publication date: February 10, 2011Applicant: ARM LimitedInventors: David John Butcher, Rhys David Copeland, Robert James Catherall, Jeremy Isle Johnson

Publication number: 20070265493Abstract: The present invention provides a ligating band dispenser that is mounted on the distal end of an endoscope. The ligator is configured to deliver multiple ligating bands to a plurality of internal sites in a patient. The ligating bands are carried on a tubular band carrier member that is retractable relative to the distal end of the endoscope in order to preserve visibility through the endoscope during navigation, then extendable to define a suction chamber for tissue aspiration during band delivery. A tubular band driver member is slidable over the band carrier member and engages bands individually to push them off the distal end of the band carrier and onto a selected treatment site. A single-hand operated control handle for selectively operating the extension of the band carrier and movement of the band driver to release a band is also provided and is slidably and removably mounted to the endoscope shaft.Type: ApplicationFiled: March 12, 2007Publication date: November 15, 2007Applicant: CONMED ENDOSCOPIC TECHNOLOGIES, INC.Inventors: Christopher Zirps, Timothy Membrino, Scott Reed, Ernest Corrao, Stephen Maguire, Eric Mears, David Copeland, John Murphy, Joseph Logan, Sean Silva, Stephen Yardan

Publication number: 20070191674Abstract: The present invention provides an endoscopic accessory control system that resides externally of the endoscope. The system comprises the endoscopic accessory with a working end to be placed at the distal end of the endoscope, a control sheath extending proximally external to the endoscope and a control handle joined to the proximal end of the control sheath. The control handle is slidably mounted to the exterior surface of the endoscope shaft and is configured to permit grasping of both the shaft and the handle. With the control handle and endoscope shaft grasped with one hand, the other hand of the user is left free to manipulate the endoscope distal tip controls. Additionally, the external arrangement of the control sheath leaves the working channel of the endoscope free for use of accessories or operations.Type: ApplicationFiled: April 18, 2007Publication date: August 16, 2007Applicant: C.

Publication number: 20070089235Abstract: A pump assembly for an emergency eyewash station and method of retrofitting a plumbed emergency eyewash station is disclosed. The pump is configured into two parts, an impeller assembly and a drive assembly, that are configured to couple together. The impeller assembly is isolated from the drive assembly and can be easily replaced to ensure a sterile fluid path is maintained for the eyewash fluid. The drive assembly can be fluid powered or an electric motor as desired. The present invention allows a plumbed eyewash station to be retrofitted to use a sterile eyewash fluid. The present invention can also be used in portable eyewash station units too.Type: ApplicationFiled: October 23, 2006Publication date: April 26, 2007Applicant: FENDALL, INC.Inventors: Benoit Devinat, David Copeland, Michael Pereira
