International Classification:

G06F 116

US Classification:

361687, 361695, 318471

Abstract:

A method and system of controlling a cooling fan of a computer system including a power supply unit. The method includes sensing a power load of the power supply unit. A reference air temperature of the computer system is also sensed. Finally, a fan setting is determined based upon the sensed power load and the sensed reference air temperature. By basing the fan setting on both reference temperature and actual power supply load, the method and system effectively minimizes cooling fan operation, and thus resulting acoustic noise, when a computer system is operating at less than full capacity. In one preferred embodiment, a look-up table is provided in which a plurality of fan settings are included, each fan setting being based upon a correlation of power supply load and reference temperature. The method and system of the present invention is particularly useful with high-end, server-type computer systems being used for low-end applications, and is readily applied to multiple platforms.

US Classification:

712 37, 712 38, 712 39

Abstract:

A single-IC subsystem controller for controlling electronic devices and subsystems within computer systems and other large electronic systems. The single-IC subsystem controller includes a micro-controller, a complex programmable logic device, an EEPROM, an SRAM, and various electronic bus interfaces and additional signal long interfaces for interfacing the single-IC subsystem controller device to electronic devices and electrical components. The single-IC subsystem controller allows for flexible partitioning of control functionality between hardware circuits programmed into the CPLD and software routines executed by the micro-controller.

International Classification:

G06F 1100

US Classification:

39518501

Abstract:

A memory module within a computing system includes a management memory. The management memory provides permanent storage for management information. For example, an error log is stored within the management memory. The error log indicates a time stamp for errors which occur in operation of the memory module. The error log consists of, for example, two lists. A first list indicates a time stamp for each (soft) correctable error which occurs in operation of the memory module. A second list indicates a time stamp for each (hard) non-correctable error which occurs in operation of the memory module.

Abstract:

A monitoring system within a computing system is set out. The monitoring system monitors components within the computing system. The monitoring system includes a plurality of monitoring devices, a dedicated bus and a controller. The dedicated bus is dedicated for use by the monitoring devices. Each monitoring device is connected to the dedicated bus. The controller is also connected to the dedicated bus. The controller assigns addresses to each monitoring device, stores exception events, and reports the exception events to system software for the computing system.

International Classification:

H02J 306

US Classification:

307 80

Abstract:

The present invention provides a low cost, low complexity, redundant power supply for an electronic data system. The low complexity of the system minimizes system failure rate while the redundancy improves system availability. The redundant power supply interconnect system is comprised of: a first electronic device including a first power supply; a second electronic device including a control means, a second power supply and a third power supply, wherein the first power supply means of the first electronic device is electrically coupled to the control means of the second electronic device; a first dedicated bus electrically coupling the first electronic device to the second electronic device; and a first serial management bus, the first serial management bus electrically coupling the first electronic device to the control means of the second electronic device.

International Classification:

G06F 1100
G06F 1126

US Classification:

371 161

Abstract:

A computer software-related device and method uses regression testing techniques for testing computer hardware and/or software application(s). Input data and commands from a user are stored, and are sent to a hardware/software system under test. Signatures (representative of visual display data) which are received (with a selected prevalence) as a result of the sent input data and commands are also stored. On command of a user, the stored signatures, input data and commands are subsequently sent to the hardware/software system under test, and new signatures are generated. These new signatures are compared with the stored signatures, and the results of this comparison are used as an indication that the hardware/software system under test is performing as expected.

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

G06F 1100

US Classification:

371 671

Abstract:

A computer hardware-related device and method is used for regression testing techniques involving the testing of computer hardware and/or software application(s). Input data is received from a host, and is directed to software application(s) on a System Under Test (SUT). Command are also received from the host, which causes the capture of a representation of visual display data from a visual display device on the SUT. A representation of this visual display data is then sent to the host. When a command and a representation of visual display data from the host (previously obtained from the SUT) is received, a new representation of visual display data is captured from the visual display device on the SUT. A comparison is then made between the new visual display data representation and the visual display data representation received from the host.

International Classification:

US Classification:

395575

Abstract:

A computer related system and method uses regression testing techniques for testing computer hardware and/or software application(s). Input data and commands from a user are stored on a host, and sent to an interface device, which then sends them to a hardware/software system under test. Visual display data on a visual display device is thereby affected. Signatures (representative of the visual display data) are generated by the interface device as a result of input data and commands sent to the interface device and system under test. These signatures are received and stored by the host. On command of a user, the stored signatures, input data and commands are subsequently sent to the hardware/software system under test, and new signatures are generated. These new signatures are compared with the stored signatures, and the results of this comparison are used as an indication that the hardware/software system under test is performing as expected.
