Patent number: 8065481Abstract: A RAID system is provided which can be implemented as a hardware RAID system while avoiding certain shortcomings of previous RAID systems. The RAID system makes it possible to avoid or reduce the number of buffers or processors and can take advantage of drive logic to achieve RAID functions or enhancements. RAID functionality can be provided in a manner to accommodate one or more ATA drive interfaces. To avoid drive replacement problems, host requests for drive serial numbers are responded to with a mirror serial number. In one embodiment, the read address is used to select which drive will perform a read operation.Type: GrantFiled: April 20, 2004Date of Patent: November 22, 2011Assignee: Seagate Technology LLCInventors: Bernhard Hiller, Pantelis Alexopoulos, Don Brunnett, Chandra Buddhavaram, Thierry Chatard, David Chew, Samuel R.

Patent number: 8005267Abstract: An apparatus for the automatic inspection of a motor vehicle has an identification and psychological profiling zone, an automatic inspection zone and a manual inspection zone. A biometric and heart rate detection station and an attached console are located in zone one. Undercarriage scanning equipment and an explosives detection portal are located in zone two. The apparatus also has one or more fixed cameras, an alarm or other alerting mechanisms and a physical barrier. A vehicle detection mechanism detects the entry of a vehicle into zone two and captures an image of the vehicle number plate. When the captured biometric data and number plate data indicate that the driver is authorized to drive the particular vehicle into the secured zone, and if no abnormalities or foreign objects in the undercarriage image are detected, the driver is allowed to proceed.Type: GrantFiled: October 16, 2008Date of Patent: August 23, 2011Assignee: Stratech Systems LimitedInventor: Khien Meow David Chew
