Appl. No.:

08/940928

Inventors:

Mitchell A. Markow - Spring TX
Jeremy Ford - Spring TX

Assignee:

Compaq Information Technologies Group, L.P. - Houston TX

International Classification:

G06F 1700

US Classification:

700 94, 381 98, 381103, 333 28 R, 379406, 379410

Abstract:

A speakerphone of a system with a digital signal processor, such as a computer, uses a filter set or network to provide acoustic coupling loss at a microphone to offset acoustic coupling gain produced by sound reflections resulting from various conditions in the system. The filter network processes an acoustic signal before the signal is provided to a digital signal processor to eliminate acoustic coupling gain that the digital signal processor is unable to cancel or offset. The filter network detects when the acoustic coupling gain in the acoustic signal at the microphone exceeds the maximum amount of acoustic coupling loss supplied by the digital signal processor. Alternatively, if acoustic coupling gain is desirable at the frequency location of the anomaly caused by the sound reflections, the filter network is used to boost the acoustic coupling gain produced by the anomaly. Thus, the present speakerphone uses equalization at the microphone to boost or attenuate acoustic coupling gain caused by frequency anomalies before acoustic echo cancellation by the digital signal processor.

Assignee:

Dell Products L.P. - Round Rock TX

International Classification:

G06F 17/30

US Classification:

726 2, 713 1, 713 2

Abstract:

Methods and systems for providing embedded user authentication and/or providing computing services using an information handling system configured as flexible computing node, and which may be implemented to perform preboot authentication of users. The flexible computing node may also be configured to provision the appropriate work environment for a given user based on one or more user parameters (e. g. entitlements, location, network connection, and/or other parameters).

Appl. No.:

12/263699

Inventors:

Jeremy M. Ford - Spring TX, US
Fahd B. Pirzada - Austin TX, US

Assignee:

DELL PRODUCTS, LP - Round Rock TX

International Classification:

G06F 9/455

US Classification:

718 1

Abstract:

An information handling system is disclosed that is configured to execute multiple virtual machines simultaneously. The information handling system can assign graphical processing resources to each virtual machine based on the estimated workload for each machine. In addition, the information handling system can change the amount of graphical resources assigned to each virtual machine in response to changing workload estimations.

Appl. No.:

8/941580

Inventors:

Mitchell A. Markow - Spring TX
Jeremy Ford - Spring TX
Ji-An Gong - Houston TX

Assignee:

Compaq Computer Corporation - Houston TX

International Classification:

H04B 1500

US Classification:

381 93

Abstract:

A method and apparatus for controlling acoustic gain during a non-speakerphone audio mode of computer system independent of acoustic gain during a speakerphone mode of the computer system is provided. The BIOS code of the computer system detects whether the computer system is in a speakerphone mode or a non-speakerphone audio mode. If the computer system is in a speakerphone mode, an upper gain limit is not applied to the microphone path of the computer system. If the computer system is in a non-speakerphone audio mode, a predetermined upper gain limit is applied to the microphone path of the computer system. The predetermined upper gain limit is preferably applied to the microphone path at either a microphone pre-amplifier or an audio mixer chip in the microphone path of the computer system.
