HP Assigned Four Patents

Managing I/O request in storage system

Hewlett-Packard Development company, LP, Houston, TX, has been assigned a patent (8,341,314) developed by Kishore Kumar Muppirala, Satish Kumar Mopur, and Dinkar Sitaram, Karnataka, India, for "managing I/O request in storage system."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "The host interface module is configured to receive a plurality of I/O request which includes an associated priority; create an I/O request queue for each associated priority; define a threshold value for the queue length for each of the plurality of I/O request queues; and determine if the queue length for one of the plurality of the I/O request queue corresponding to the associated priority is less than the defined threshold value for the queue length for the one of the plurality of the I/O request queues. If the queue length of the one of the plurality of I/O request queues is more than the defined threshold value for the queue then the host interface module is further configured to rejecting the I/O request and sending a queue full message; wherein the threshold value for the queue length is based on the processing rate of the I/O requests in the plurality of the I/O request queues."

The patent application was filed on March 25, 2010 (12/731,153).

Information storage system

Hewlett-Packard Development company, LP, Houston, TX, has been assigned a patent (8,354,995) developed by Ian N. Robinson, Pebble Beach, CA, for an "information storage system."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A system for storing information includes a computing device having a display and a processor for controlling the display. The system includes a portable storage device configured to communicate with the computing device. The portable storage device includes a PSD display, a PSD processor configured to control the PSD display, and a PSD memory. The system also includes an input mechanism configured to enable selection of information displayed on at least a portion of the display and to activate an information capture application. In addition, the information capture application is configured to assign a visual cue to the selected information. The information capture application is further configured to store the selected information and the assigned visual cue in the PSD memory in response to activation of the input mechanism."

The patent application was filed on April 30, 2004 (10/835,174).

Optical storage medium with optically detectable marks

Hewlett-Packard Development company, LP, Houston, TX, has been assigned a patent (8,339,920) developed by Charles R. Weirauch, Loveland, CO, for "optical storage medium with optically detectable marks."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Optically detectable marks readable by a wide range of optical systems are included on an optical storage medium. Among other uses, the marks may be used to determine the type of the optical storage medium in an optical device capable of reading multiple types of optical storage media."

The patent application was filed on July 10, 2003 (10/618,115).

Data transfer device

Hewlett-Packard Development company, LP, Houston, TX, has been assigned a patent (8,341,429) developed by Jonathan Peter Buckingham, Bristol, UK, Liqun Chen, Bristol, UK, and Christopher Williams, Devauden/Chepstow Wales, UK, for a "data transfer device".

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A data transfer device for transferring data to a removable data storage item. The data transfer device receives content data to be stored to the removable data storage item, encrypts the content data using an encryption key, and transforms at least one of predetermined reference data and the encryption key. The data transfer device also encrypts the transformed predetermined reference data using the encryption key or encrypts the predetermined reference data using the transformed encryption key, and then stores the encrypted content data and the encrypted transformed/predetermined reference data to the removable data storage item."

The patent application was filed on Sept. 28, 2008 (12/239,806).
