Patent number: 8244427Abstract: A vehicle includes a power inverter module (PIM), a motor/generator unit (MGU), vehicle components, temperature sensors, and a controller. The sensors measure temperatures of a motor winding of the MGU, and temperatures of the multiple phase outputs of the PIM. The second plurality of temperature sensors measures temperatures of the vehicle components. The controller calculates an average temperature of the components, and individually diagnoses each temperature sensor using the average temperature. A control circuit for the vehicle includes the first and second plurality of sensors and the controller. A temperature performance diagnostic method includes using the first plurality to measure a temperature of the motor winding and the phase outputs of the PIM, using the second plurality to measure a temperature of the components, calculating an average temperature of the components, and individually diagnosing the performance of each of the first plurality of sensors using the average temperature.Type: GrantFiled: May 24, 2010Date of Patent: August 14, 2012Assignees: GM Global Technology Operations LLC, Hewlett-Packard Development, L.P.Inventors: Robert Weiss, Thomas E Mathews, Andrew M.

Patent number: 7740920Abstract: Silica-based, chemically-bonded porous coatings, synthesized via the reaction of organo silanes with silica, are used as coatings for inkjet image printing. Silica is used as the base material in all cases, due to its favorable chemical properties of the surface, and the favorable pore structure. The silane-silica reaction product substantially retains the original pore structure of the pre-reacted silica. The disclosed embodiments solve the problems in the prior art in that any catalytic activity of the silica surface towards image fade is eliminated by the chemical modification of silica. This improves the image fade and humid fastness properties of the coating.Type: GrantFiled: October 10, 2008Date of Patent: June 22, 2010Assignee: Hewlett-Packard Development, L.P.Inventors: Palitha Wickramanayake, James P.

Patent number: 7426728Abstract: One embodiment disclosed relates to a method of reducing access latency to a task priority register (TPR) of a local programmable interrupt controller unit within a microprocessor. A command is received to write an interrupt mask value to the TPR, and the interrupt mask value is written to the TPR. In addition, the interrupt mask value is also written into a shadow copy of the TPR. The shadow copy is written each time that the TPR is written. Another embodiment disclosed relates to a method of reducing a latency to read a TPR of an IPF type microprocessor. When a command is received to read an interrupt mask value from the TPR, the interrupt mask value is read from the shadow copy at a memory location, instead of from the task priority register itself.Type: GrantFiled: September 24, 2003Date of Patent: September 16, 2008Assignee: Hewlett-Packard Development, L.P.Inventors: Christopher Philip Ruemmler, Jonathan K. Ross

Patent number: 7353507Abstract: Intercepting function calls. In one embodiment of the application, an import address table for an application is accessed and an address, in the import address table, associated with a function to which calls from the application are to be intercepted is replaced with an address to be used to access a proxy function. In another embodiment, the application is loaded in debugging mode. Once the import address table for the application has been populated with addresses for functions called by the application, the execution of the application is paused. An address, in the import address table, associated with a function to which calls from the application are to be intercepted is replaced with an address to be used to access a proxy function. Execution of the application is then resumed.Type: GrantFiled: October 30, 2002Date of Patent: April 1, 2008Assignee: Hewlett-Packard Development, L.P.Inventors: Charles J.

Patent number: 7305497Abstract: A method of performing resource analysis on one or more cards of a computer system is described and disclosed. In an embodiment, the method includes identifying one or more affected hardware identifiers. Each affected hardware identifier corresponds to any of the cards. Configuration information of the computer system is gathered. Moreover, the configuration information is used to analyze the affected hardware identifiers to identify any affected resource of the computer system. The identification of any affected resource is independent of a system-wide hardware scan of the computer system. Furthermore, one of a plurality of severity levels is assigned to each identified affected resource based on predetermined criteria. The severity levels include a low severity level, a medium severity level, and a high severity level. Each severity level represents degree of impact to the computer system if functionality of the identified affected resource became unavailable.Type: GrantFiled: May 24, 2004Date of Patent: December 4, 2007Assignee: Hewlett-Packard Development, L.P.Inventors: Ryan Ray Houdek, Toran Kent Kopren, Wade James Satterfield

Patent number: 7210061Abstract: A technique for using a remote array cache memory for data redundancy. A computer system includes a first storage system having cache memory and mass storage. Data to be written to the mass storage is written to the cache memory. Redundant data is stored elsewhere in case the cache experiences a fault before the data can be written to mass storage. Otherwise, data not yet written to the mass storage may be lost. The first storage system is in communication with a second storage system which is typically located remotely from the first storage system. When the first storage system receives a write request, the first storage system forwards the data to the second storage system for redundant storage. Where the data is forwarded to the second storage system, this is referred to herein as “remote mode.” The first storage system may include redundant cache memories and enters remote mode only in the event a fault affects one of the cache memories.Type: GrantFiled: April 17, 2003Date of Patent: April 24, 2007Assignee: Hewlett-Packard Development, L.P.Inventor: Eric Anderson

Patent number: 7184542Abstract: The present invention relates to the field of tone detection and, more particularly, to the detection of dual tone multi-frequency (DTMF) tones in software based telecommunications systems. As modem telecommunications systems are becoming increasingly software based and typically require only a minimum of physical hardware, much of the necessary telecommunication functionality is now provided by software functions running on powerful computer servers. A common function which is required to be performed by telecommunications systems is that of dual tone multi-frequency (DTMF) detection. Accordingly, the present invention aims to provide an efficient software-based DTMF detection system that satisfies the ever increasing need for efficient software functions.Type: GrantFiled: February 7, 2003Date of Patent: February 27, 2007Assignee: Hewlett-Packard Development, L.P.Inventors: Pierre Sauvage, Simon Morlat
