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.

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:

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:

G06K 1500

US Classification:

395109

Abstract:

A method processes a plurality of bits stored in a first memory and representing an image to be printed by reproducing the bits in a fast scan direction. The method includes the step of reading a plurality of groups from the first memory into a second memory, wherein each of the groups comprises a number of bits greater than one bit and is stored in the second memory in the fast scan direction, and wherein each group is read one group at a time. Further, the method includes copying a predetermined number of bits from each of the plurality of groups to a sample storage area. After the copying step, the method samples the bits of the copied groups wherein the sampled bits form a pattern having a center bit having a binary state. Finally, after the sampling step, the method outputs a print signal representative of the binary state if the pattern does not match a predetermined pattern, or outputs a print signal different than the binary state if the pattern matches a predetermined pattern.

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.
