VideoIQ Assigned Patent

VideoIQ, Inc., Bedford, MA, has been assigned a patent (8,427,552) developed by Douglas H. Marman, Ridgefield, WA, and Mahesh Saptharishi, Waltham, MA, for "extending the operational lifetime of a hard-disk drive used in video storage applications."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A storage buffer and a hard-disk drive are provided in a video storage application. The hard-disk drive operates normally in a powered-down state, and video data are stored in the storage buffer during a first time interval. The hard-disk drive is operated in a powered-up state. A portion of the video data stored in the storage buffer is transferred to and stored in the hard-disk drive in the powered-up state during a second time interval that is substantially shorter than the first time interval. The hard-disk drive is returned to the powered-down state. A total hard-disk drive storage time, representing a sum of the second time intervals, spent transferring to and storing a portion of the video data in the hard-disk drive is substantially less than a total buffer storage time, representing a sum of the first time intervals, spent storing the video data in the storage buffer."

The patent application was filed on April 18, 2008 (12/105,893).
