    Abstract: A shelving and package locating system for delivery vehicles includes one or more shelves for storing packages within a delivery vehicle during delivery. Each package is associated with both a geographic delivery address and an assigned location on a particular shelf within the delivery vehicle. A GPS unit determines the location of the delivery vehicle during delivery, and a computer provides the shelf location of a particular package when that package's delivery-location information substantially corresponds to vehicle location information. Several embodiments exist for registering the location of the package in the vehicle at load time, such as scanned location indicia, light sensors on shelves, pressure sensors on shelves, pressure sensors on the floor of the vehicle, and light spot. Several embodiments exist for locating the package in the vehicle at delivery time, such as a pick-to-light system that employs variable length lighting and a light pointer system that generates a light spot.

  • Patent number: 9865290
    Abstract: In an in-drive erase process in a single-surface HDD, erase spirals on the surface being erased can be employed to control writer position. A reader-to-writer timing offset value is determined for a plurality of radial locations on the surface to be erased, and an erase window is determined for a radial location disposed between two erase spirals. The erase window includes an erase start time, which is based on a spiral exit time of a reader and the reader-to-writer timing offset value for the radial location, and an erase stop time, which is based on a spiral encounter time of the reader and the reader-to-writer timing offset value. The erase window prevents complete erasure of erase spirals, so that the servo system of the HDD can continue to servo off of the erase spirals. The erase spirals may be written with a lower slope than conventional spiral tracks.

  • Patent number: 9547448
    Abstract: A system and method of transposed storage in RAID arrays includes a storage manager with an interface for receiving storage requests associated with multi-segment blocks stored in a storage array, a controller for processing the received storage requests and controlling the storage manager, and a write request handler. The storage array includes a plurality of storage devices for which consecutive logical addresses are assigned to different ones of the storage devices. The write request handler is configured to process block write requests and send segment write requests to the storage array based on the write requests so that each segment of a given multi-segment block is written to a single respective one of the storage devices in the storage array. In some embodiments, the storage manager further includes a read request handler configured to determine logical addresses of requested segments and send segment read requests to the storage array.

  • Patent number: 9489976
    Abstract: Technologies are described herein for adapting channel parameters of a read channel in a transformed space. A set of channel parameter values associated with one or more components of the read channel is received. A general transformation is performed on the channel parameter values, and insignificant terms in the transformed space are filtered out. Next, an inverse transformation is performed on the filtered terms in the transformed space to calculate a new set of channel parameter values for the component(s).

  • Patent number: 9448732
    Abstract: Described is storage system and method for reducing power consumption. The storage system has first and second physical disks configured to provide mirroring. The first physical disk is placed into a power-saving mode of operation, while the second physical disk is in an active mode of operation responding to read and write requests. The first physical disk transitions from the power-saving mode of operation to an active mode of operation for destaging writes pending from cache to the first physical disk, while the second physical disk responds to read and write requests. The second physical disk transitions from the active mode of operation to the power-saving mode of operation, while the first physical disk responds to read and write requests.

  • Patent number: 9390749
    Abstract: A disk drive is disclosed comprising a disk, a spindle motor operable to rotate the disk, a head actuated over the disk, an interface operable to receive a host supply voltage, and a capacitor. The host supply voltage is used to charge the capacitor to a capacitor voltage higher than the host supply voltage. During a power failure, the host supply voltage stops charging the capacitor, and a motor supply voltage is generated from the spindle motor. The capacitor voltage is used to operate control circuitry, and when the capacitor voltage decays below the motor supply voltage, the motor supply voltage charges the capacitor.
