Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06F 1300

US Classification:

710303, 713300, 713310

Abstract:

A laptop computer and mating docking station where the docking station provides power to the laptop computer over power rails of the Universal Serial Bus (USB) interface. The laptop computer has laptop docking logic that both provides power in accordance with standard USB protocol, and also receiving power across the power rails of the USB interface. Likewise, the docking station has a docking station dock logic that establishes communication with the laptop docking logic across the USB power rails. Once positive communication is established, the dock station provides voltages on the USB power rails sufficient to power the laptop computer as well as charge the laptops battery.

Appl. No.:

11/700482

Inventors:

Michael J. Dougherty - Houston TX, US
Chandrakant Patel - Fremont CA, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06F 11/00

US Classification:

714 47

Abstract:

A digital media drive failure prediction system comprises a prediction module configured to analyze a current draw associated with a digital media drive measured at least two different operating times of the digital media drive to automatically determine whether a different between the measured current draws indicates an impending failure of the digital media drive.

Appl. No.:

10/957229

Inventors:

Michael Joseph Dougherty - Houston TX, US
John Phillip Powell - Spring TX, US
Robert Eugene Krancher - Houston TX, US

International Classification:

G06F 15/16

US Classification:

709228000

Abstract:

Systems and methods of automatic activation and deactivation of a wireless network adapter are disclosed. In one embodiment, a wireless network adapter and a wired network adapter included in a system are controlled by determining if the wired network adapter has established a wired communication link and, if the wired communication link has been established, automatically disabling the wireless network adapter.

International Classification:

G06K 1500

H04N 129
H04N 1409

US Classification:

395107

Abstract:

A method and apparatus for conserving a substance dispensed by a printer engine for forming print on a media. As an example, the method stores a plurality of bits in a memory, the plurality of bits representing a cumulative pattern to be printed by reproducing the bits on the media. Each bit is either in a first memory state or a second memory state. The method further selects a subset of the plurality of bits, wherein the subset forms a first pattern and has a center bit. If each of the plurality of bits of the subset is in the first memory state, the method outputs to the printer engine a print bit corresponding to the center bit and in a print state which is opposite the memory state of the center bit. If, however, at least one of the plurality of bits of the subset is in the second memory state, the method outputs to the printer engine a print bit corresponding to the center bit and in a print state the same as the memory state of the center bit.

International Classification:

H02P 767

US Classification:

318434

Abstract:

To improve the reliability and lower the cost of electronic control circuits for direct current (DC) motors, the need for external mechanical sensors is eliminated through the use of low cost, highly reliable voltage comparator circuits. A motor driver integrated circuit provides for electronic storage of data, automatic execution of computer programs, and input/output transfer of various electronic signals used in the control of the DC motor. The voltage comparator circuits sense the operating state of the DC motor by comparing the motor current sense voltage, which is proportional to the torque of the motor, to threshold fixed reference voltages to determine whether the DC motor is running normally or is stalled. The motor driver IC stops or reverses the DC motor when it is stalled, thereby preventing damage and providing for fully automatic operation without external sensors.
