Draining Residual Charge From A Voltage Plane

View page
US Patent:
7120805, Oct 10, 2006
Filed:
Apr 11, 2003
Appl. No.:
10/412526
Inventors:
Joshua N. Alperin - Round Rock TX, US
Glenroy Devonish - Round Rock TX, US
Ajay Kwatra - Austin TX, US
Todd W. Schlottman - Round Rock TX, US
Assignee:
Dell Products L.P. - Round Rock TX
International Classification:
G06F 1/26
H03L 5/00
US Classification:
713300, 327309
Abstract:
An energy discharge resistance is isolated from storage capacitance containing a voltage charge until power is removed from the storage capacitance. Then the discharge resistance may be coupled to the storage capacitance to drain residual charge therefrom. The discharge resistance is coupled to the storage capacitance when external power is removed and is un-coupled from the storage capacitance when external power is applied to the storage capacitance. In this way, unnecessary power draw during operation or standby of an electronic system is substantially eliminated.

System And Method For Information Handling System Cooling Fan Operating Parameter Selection

View page
US Patent:
7139169, Nov 21, 2006
Filed:
Dec 11, 2003
Appl. No.:
10/733910
Inventors:
Joshua N. Alperin - Round Rock TX, US
Ajay Kwatra - Austin TX, US
James Shields - Cedar Park TX, US
Benjamen G. Tyner - Norman OK, US
Assignee:
Dell Products L.P. - Round Rock TX
International Classification:
G06F 1/20
G06F 19/00
H05K 7/20
G05B 11/01
G05D 23/00
US Classification:
361687, 361695, 702 99, 700 25, 700299
Abstract:
An information handling system cooling fan operating curve is automatically selected for use by a cooling fan controller by detecting the configuration of the information handling system and looking up cooling fan operating parameters from a table associated with the information handling system. For instance, central processing unit identification information is used to select associated cooling fan operating parameters so that adequate cooling is available to meet system cooling constraints for the heat characteristics of the central processing unit with reduced acoustic impact associated with operation of the information handling system.

Method And System For Validating Physical Access To An Information Handling System

View page
US Patent:
7200861, Apr 3, 2007
Filed:
Mar 27, 2003
Appl. No.:
10/401294
Inventors:
Joshua N. Alperin - Round Rock TX, US
Benjamen G. Tyner - Austin TX, US
Assignee:
Dell Products L.P. - Round Rock TX
International Classification:
H04L 9/32
US Classification:
726 2, 726 3, 726 34
Abstract:
An information handling system security system validates authorization to selected information by establishing physical access of a user to the information handling system through activation by the user of a power switch of the information handling system. Upon detection of an attempt to access the limited access information, a trusted platform module disables power functionality of the power switch and enables a physical access validation mode that validates physical access of a user to the information handling system before allowing access to the limited access information. Failure to confirm physical access by activation of the power switch precludes access to the information. Validation of physical access by activation of the power switch allows access to the information and returns normal power functionality to the power switch.

Apparatus To Facilitate Functional Shock And Vibration Testing Of Device Connections And Related Method

View page
US Patent:
7282925, Oct 16, 2007
Filed:
Oct 25, 2004
Appl. No.:
10/972752
Inventors:
Joshua N. Alperin - Round Rock TX, US
Jeffrey M. Cardwell - Austin TX, US
Matthew J. McGowan - Austin TX, US
Assignee:
Dell Products L.P. - Round Rock TX
International Classification:
G01R 31/04
G01R 31/26
US Classification:
324538, 324765
Abstract:
An apparatus and associated method are disclosed for facilitating the testing of device connections, including functional shock and vibration testing of peripheral card slots or any other desired connector interface. In part, a power supply located on the peripheral device, or some other external power source, is used to power fault detection circuitry. In this way, faults can be identified, such as through visual fault indicators, without the necessity of powering the system. In addition, simulated peripheral cards are provided that include adjustable weights so that the weight distribution of an actual card can be simulated without the necessity of having a functional peripheral in hand.

Hybrid Laser And Inkjet Printer

International Classification:
B41J 29/38
US Classification:
347 16, 347 2, 347 14
Abstract:
A printer which includes both high volume printing capabilities such as laser jet printing with photographic quality printing capabilities such as ink jet or dye-sublimation printing within the same printer housing.

Memory Security Override Protection For Manufacturability Of Information Handling Systems

View page
US Patent:
8132253, Mar 6, 2012
Filed:
Apr 21, 2008
Appl. No.:
12/148643
Inventors:
Ricardo L. Martinez - Austin TX, US
Richard Brian Wallace - Pflugerville TX, US
Joshua N. Alperin - Round Rock TX, US
Assignee:
Dell Products L.P. - Round Rock TX
International Classification:
G06F 21/00
US Classification:
726 16, 713189
Abstract:
Systems and methods are disclosed for providing memory security override protection for improved manufacturability of information handling systems. A security authentication system is added to a software driven security override signal for unlocking programmable memory circuitry, such as flash memory, according to security protection techniques associated with the Intel AMT (Active Management Technology) architecture. This security authentication system disclosed requires authentication of software security override requests before they are allowed. More particularly, the systems and methods disclosed add specific BIOS (Basic Input Output System) code to check the security override status and the software security override request signals on boots of the computer system to make sure these requests are not coming from rogue elements within the computer system. If the authentication is validated, then the programmable memory circuitry is unlocked on the next boot of the system to allow for reprogramming.

Replacement Motherboard Configuration

US Patent:
8286093, Oct 9, 2012
Filed:
Jan 9, 2008
Appl. No.:
11/971490
Inventors:
Ricardo L. Martinez - Austin TX, US
Aaron Taylor - Round Rock TX, US
Richard Brian Wallace - Pflugerville TX, US
Joshua N. Alperin - Round Rock TX, US
International Classification:
G06F 3/048
G06F 3/00
G06F 9/00
US Classification:
715810, 710104, 713 2
Abstract:
In a system to configure a replacement motherboard, one or more subsystems are provided to determine whether the replacement motherboard is in a manufacturing mode, determine whether firmware for the replacement motherboard is unlocked, and receive an input from a user to configure the replacement motherboard when the replacement motherboard is determined to be in the manufacturing mode and the firmware is unlocked.

Method And System For Restoring System Configuration After Disorderly Shutdown

View page
US Patent:
8335913, Dec 18, 2012
Filed:
Sep 8, 2008
Appl. No.:
12/206525
Inventors:
Matthew B. Mendelow - Austin TX, US
Todd W. Schlottman - Round Rock TX, US
Joshua N. Alperin - Round Rock TX, US
Assignee:
Dell Products, LLP - Round Rock TX
International Classification:
G06F 9/00
G06F 15/177
US Classification:
713 2, 714 15, 714 24, 714 36
Abstract:
Disclosed are techniques for recovering system configuration settings, such as remote management, of an information handling system following a disorderly shutdown. A restart controller detects a disorderly shutdown of an information handling system and, in response, sets a disorderly shutdown flag and restarts the information handling system. During the restart, the basic input/output system (BIOS) checks the disorderly shutdown flag as part of its power-on housekeeping. In response to determining the disorderly shutdown flag has been set, the BIOS reconfigures the system configuration settings, such as the power management scheme, of the information handling system so as to enable one or more remote wake mechanisms, such as wake-on-LAN or wake-on-ring. The BIOS then performs an orderly shutdown of the information handling system to place the information handling system in a low-power state, from which the information handling system can be awoken via the remote wake mechanism.
