Universal Serial Bus Controlled Connect And Disconnect

View page
US Patent:
6415342, Jul 2, 2002
Filed:
Jul 27, 1999
Appl. No.:
09/361952
Inventors:
Mark A Wahl - Windsor CO
Mark J Jedrzejewski - Thornton CO
Gregory A Standiford - Loveland CO
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
G06F 1300
US Classification:
710100, 710313, 710 2, 710 62, 710 72
Abstract:
A device for connection to a Universal Serial Bus (USB) signals connection and disconnection from the bus without physically removing or reinserting the USB cable. The devices system controller controls the signaling so that connection or disconnection may be signaled in a variety of situations to accomplish certain tasks. Connection signaling may be delayed until power-up reset procedures are complete to prevent the device from being polled by the host. A disconnect then a connect may be signaled to help recover from certain error conditions. The same data lines may also be used for interfaces other than the USB bus. A switched connection from a USB data line through a pull-up resistor to a positive supply voltage. The switched connection is controlled by a logic function so that it will not be connected when the power supply on the USB cable is not present. The switched connection is also controlled by a logic signal that may be supplied by the USB devices system controller.

Selection Apparatus And Method

US Patent:
6647436, Nov 11, 2003
Filed:
Aug 2, 2000
Appl. No.:
09/630522
Inventors:
Mark J Jedrzejewski - Thornton CO
Mark A Wahl - Windsor CO
Gregory A Standiford - Loveland CO
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
G06F 1314
US Classification:
710 14, 174261, 32420721, 365 63, 379399
Abstract:
Two interfaces or operating modes are designed into the hardware and firmware. Selection between these two interfaces, or operating modes, is indicated by the position of a jumper on an IDE/ATAPI-style jumper block. A pull-up resistor and interface type detection signal are connected to a pin on the IDE/ATAPI-style jumper block associated with a jumper that is not monitored by the IDE/ATAPI master/slave selection detect (or other configuration) hardware or used to pull-down or pull-up another jumpered pin on the jumper block. When a jumper is placed between this pin, and a pin used to pull-up or pull-down another jumpered pin the interface type detection signal will be read as being at the pulled-up or pulled-down logic level, respectively. Otherwise, the IDE/ATAPI master/slave selection (or other configuration) detect hardware will function normally.

Temperature Monitoring System

View page
US Patent:
7513682, Apr 7, 2009
Filed:
May 11, 2004
Appl. No.:
10/842831
Inventors:
Linden H. McClure - Millikan CO, US
Shane R. Ward - Loveland CO, US
Mark J. Jedrzejewski - Thornton CO, US
Makarand P. Gore - Corvallis OR, US
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
G01N 25/72
G01K 11/00
US Classification:
374 5, 374 4, 374162, 252962, 2524081
Abstract:
Disclosed herein is a temperature monitoring system including a circuit board and a thermochromic coating covering at least a portion of the circuit board, wherein the thermochromic coating is capable of indicating a temperature gradient on the circuit board. The thermochromic coating may comprise a color forming leuco dye, an activator, and optionally a deprotecting agent.

Configurable Driver Circuit And Termination For A Computer Input/Output Bus

View page
US Patent:
53610059, Nov 1, 1994
Filed:
Mar 31, 1993
Appl. No.:
8/040815
Inventors:
John W. Slattery - Loveland CO
Mark J. Jedrzejewski - Fort Collins CO
Terry W. Norton - Longmont CO
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
H03K 190185
US Classification:
326 56
Abstract:
A configurable driver/termination circuit for use in a peripheral device connected to a computer input/output controller bus. The driver/termination circuit has the pull-up current source characteristics of a three-state driver and the pull-down current sink characteristics of a open collector driver. Logic circuit defines the operating mode. In a default mode, the driver/termination circuit can function in either open collector or three-state bus designs. The circuit mode is changed by command from a host computer to explicitly operate as an open collector driver/terminator, as a three-state driver, or as an inactive high impedance. Alternatively, peripheral devices automatically select the mode which minimizes data transmission errors.

Automatically Configurable Video Systems With Multiple Sources And Method Of Configuring Video Systems

View page
US Patent:
20140292780, Oct 2, 2014
Filed:
Oct 27, 2011
Appl. No.:
14/350915
Inventors:
Mark J. Jedrzejewski - Loveland CO, US
Courtney D. Goeltzenleuchter - Fort Collins CO, US
Assignee:
HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P. - Houston TX
International Classification:
G09G 5/00
G06F 3/14
US Classification:
345520
Abstract:
An automatically-configurable video system having multiple video sources. Upon system power-up, if an external video signal is present, it is automatically routed to a display. If it is not present, and if a graphics subsystem video signal is present, that signal is automatically routed to the display, and if the graphics subsystem video signal is also not present, a video signal from a primary video subsystem is routed to the display.
