  • Patent number: 8642833
    Abstract: A reusable absorbent article includes a hydrophilic top layer, a soaking layer adjacent to and beneath the top layer, a substantially liquid impermeable layer adjacent to and beneath the soaking layer, and a backing layer adjacent to and beneath the substantially liquid impermeable layer. All of the layers are secured together to form a unitary structure. The soaking layer is a non-woven fabric having a plurality of hydrophobic fibers of a generally circular cross-sectional shape and a plurality of hydrophilic fibers of a non-circular cross-sectional shape.
    Type: Grant

  • Patent number: 4888691
    Abstract: A disk control system offloads to the disk controller much of the overhead associated with disk operations and makes the CPU available for other work. A command block that fully specifies a user request for a disk operation is forwarded to the disk memory unit. The command block contains a unique identifier for tracking of user requests. User requests are executed by the disk memory unit in an order that is most efficient for the disk drive system. The status of a user request is communicated to the CPU via an interrupt and a status block containing the unique identifier. The status block indicates status conditions such as command read, completion and DMA channel request. The disk driver contains a work queue for user requests that have not been forwarded to the disk memory unit and a pending queue for user requests that are awaiting completion by the disk memory unit. By manipulation of the work queues and pending queues, the disk controller can be automatically reinitialized when an error occurs.
