US Patent:

20040064718, Apr 1, 2004

Filed:

Sep 12, 2002

Appl. No.:

10/242746

Inventors:

Bradley Harrington - Austin TX, US
Kevin Locke - Austin TX, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F012/14

US Classification:

713/200000, 713/193000

Abstract:

A system, method, and computer program product are disclosed for prohibiting unauthorized access to a protected region of memory. A protected region of memory and a trusted region of memory are both specified. A call to access a location within the protected region of memory is received. An origination location of the call is then determined. In response to a determination that the origination location is within the trusted region, the call is permitted to access the protected region of memory. In response to a determination that the origination location is outside of the trusted region, the call is prohibited from accessing the protected region of memory.

International Classification:

G05D 23/19
G05B 19/048

Abstract:

Control signals, such as PWM control signals, can be used to control aspects of a cooling system and can be generated using proportional-integral-derivative (PID) control. PID control systems for cooling systems are designed based on default environmental and system characteristics and pre-programmed for operation prior to delivery to customers or end users. Changes in environmental and system characteristics, such as component aging, environmental variations, and variation in manufacturing from system to system, such as heat sink effectiveness and application of thermal pastes, can impact system level performance of the control system. Adjusting gain parameters for the P, I, and D components of a PID control signal can reduce negative impact on system performance resulting from such changes and allow the control system to better adjust to external factors.

Travis North - Cedar Park TX, US
Andrew Ingalls - Round Rock TX, US

Assignee:

Dell Products L.P. - Round Rock TX

International Classification:

G06F 1/20
G05D 23/19
G05D 13/62
G05D 27/02
G05B 15/02

Abstract:

Adjusting a cooling fan speed control profile to account for system implementation factors, such as ambient temperature and usage history, can optimize power consumption and reduce the volume and variation of sound generated by shifts in fan speed in response to changes in system and component temperature. Adjusting a cooling fan speed control profile may include adjusting a maximum fan speed based on an ambient temperature or component temperature of the information handling system.

Appl. No.:

15/205488

Inventors:

Adolfo S. Montero - Pflugerville TX, US
Kevin B. Locke - Austin TX, US

International Classification:

G06F 1/20
G06F 3/0484
G06F 3/0481
G05D 23/19

Abstract:

Systems and methods are provided that may be implemented for facilitating user modification of cooling device speed response to sensed temperature in information handling systems. The disclosed systems and methods may be implemented to allow an information handling system user to modify how one or more individual cooling device/s respond to device speed control values specified by stored device speed control information without requiring the user to change the identity or pre-defined device speed values of the device speed control information with which the information system is currently operating.

Appl. No.:

14/273173

Inventors:

Kevin B. Locke - Austin TX, US

International Classification:

G06F 21/57
G06F 21/56

Abstract:

Methods and systems for implementing pre-boot software verification may involve using an embedded controller (EC) and a basic input/output system (BIOS) to confirm each other's firmware using hash values. The hash values may be generated from certain portions of the firmware, which may overlap and may be specific to a particular firmware version.
