Patent number: 9133605Abstract: A hydraulic system has a variable displacement pump that sends fluid from a tank into a supply conduit from which separate open-center control valves convey the fluid to each one of a plurality of hydraulic actuators. The control valves have open-center orifices connected in series between a bypass node and the tank, thereby forming a bypass passage. Pressure at the bypass node controls displacement of the pump. A valve arrangement is connected between an outlet of the pump and the bypass node and is responsive to an amount of fluid flow through the supply conduit to the plurality of hydraulic functions, wherein as the amount of fluid flow increases, the valve arrangement causes fluid flow to the bypass node to decrease. Thus the pressure at the bypass node varies as a function of the operation of the control valves.Type: GrantFiled: February 27, 2012Date of Patent: September 15, 2015Assignee: HUSCO International, Inc.Inventors: Paul Edward Pomeroy, Robert Jonathan Valenta, Mark Jervis

Patent number: 8959136Abstract: Efficient matrix operations circuitry is based on combining a matrix decomposition and a forward substitution operations to share the same processing overhead. A dual multiplier circuit selectively applies complex multiplication operations to a first and second input vectors for computing a conjugate dot product vector or a non-conjugate dot product vector. The conjugate dot product vector corresponds to the matrix decomposition operation for triangulating an input matrix to generate an element of a triangulated matrix. The non-conjugate dot product vector corresponds to a forward substitution operation for determining an element of a forward substitution vector from the triangulated matrix.Type: GrantFiled: May 8, 2012Date of Patent: February 17, 2015Assignee: Altera CorporationInventors: Colman C. Cheung, Steven Perry, Volker Mauer, Mark Jervis

Publication number: 20100015009Abstract: A cartridge (10) for dispensing a reagent contained in a reagent reservoir (32). The reservoir (32) is in fluid communication with a deformable dispense tube (26) that is a least partially compressible, in use, to dispense a volume of reagent from the tube (26). The reservoir (32) defines an enclosed gas space (46) above the reagent, and the cartridge (10) includes a gas vent (40) that, in use, admits gas to the gas space (46) in response to dispense of reagent from the tube (26) that serves to control the reservoir pressure as the reservoir (32) is depleted by subsequent dispensing of reagent. A dispenser employing the cartridge (10) and a method of dispensing a volume of reagent are also disclosed.Type: ApplicationFiled: April 13, 2007Publication date: January 21, 2010Applicant: IMI VISION LIMITEDInventors: Mark Andrew Wallace, Hugh Christopher Bramley, Mark Jervis

Patent number: 7530046Abstract: While debugging, a user chooses an incremental recompile. Internal signals of interest are selected and output pins are optionally reserved. An incremental recompile of the compiled design includes compiling a routing from each internal signal to an output pin. The technology-mapped netlist and placing and routing information corresponding to an original compiled design are saved into a database during full compilation. During debugging, an incremental compiler retrieves this information to build the original routing netlist. The database building, logic synthesis and technology mapping stages may be skipped. New connections are added, fitted to the device, and then the final routing netlist is output into a programming output file (POF) in a form suitable for programming the PLD. The user views the internal signals at the output pins chosen. The user may iterate through this process many times in order to debug the PLD. The debugging assignments may be deleted.Type: GrantFiled: May 18, 2006Date of Patent: May 5, 2009Assignee: Altera CorporationInventors: Gregor Nixon, Mark Jervis, Zhengjun Pan, Gihan De Silva, Steven Perry

Patent number: 7206967Abstract: While debugging, a user chooses an incremental recompile. Internal signals of interest and output pins are selected, and a number of additional registers are chosen to insert in the path of each internal signal. A clock is selected for the registers. An incremental recompile of the compiled design compiles a routing from each internal signal to an output pin via the added registers. The database building and logic synthesis stages are skipped. The post-fitting logical netlist and routing netlist are retrieved. The new registers are created and the internal signal is connected to the output pin atom in the logical netlist. The fitter places and routes the connections to create a new routing netlist and then the new routing netlist is output into a programming output file (POF) in a form suitable for programming the PLD. The original routing netlist is undisturbed. The user views the internal signals at the output pins chosen. The user may iterate through this process many times in order to debug the PLD.Type: GrantFiled: February 9, 2004Date of Patent: April 17, 2007Assignee: Altera CorporationInventors: Philippe Marti, Mark Jervis, Gregor Nixon

Publication number: 20050072474Abstract: A member that is driven by a hydraulic actuator tends oscillate when fluid flow to the hydraulic actuator is terminated. A pressure relief device reduces that oscillation by connecting first and second first relief valves to the hydraulic actuator. The first relief valve provides a relatively large first relief passage as long as pressure in the hydraulic actuator remains above a threshold. A second relief valve opens a second relief passage at substantially the same threshold pressure and thereafter remains open as long as the pressure remains above another lower threshold. A timer causes the second relief valve to close a given interval of time, if the pressure does not drop below the other lower threshold.Type: ApplicationFiled: October 1, 2003Publication date: April 7, 2005Inventors: Mark Jervis, Robert Valenta, Lynn Russell, Sean Haggerty

Publication number: 20050072145Abstract: In a hydraulic system that has first and second pumps, a pressure compensation circuit is provided to unload the output of the second pump when its operation is not required. The unloading reduces the power demanded of the engine that drives the pumps thus conserving energy. The first pump is directly connected to a supply line and a back flow check valve couples the second pump to the supply line. When pressure in the supply line is significantly greater than the load pressure of the actuators powered by the hydraulic fluid a bypass compensator valve opens to provide a path between the outlet of the second pump and the tank line. This action unloads the second pump and reduces its demand for engine power.Type: ApplicationFiled: October 1, 2003Publication date: April 7, 2005Inventor: Mark Jervis
