  • Patent number: 5814070
    Abstract: A suture anchor and driver device is described that is designed to secure a suture anchor to a bone in a patient to allow soft tissue or the like to be secured to the bone. The suture anchor itself engages the suture along the length of a passage that passes through the diameter of the distal end of the suture anchor, providing for a relatively large area of engagement to minimize stress on the suture material. The driver is designed to engage the suture anchor and guide the suture material along outside surface of the driver.

  • Patent number: 5719786
    Abstract: A computer-based media data processor for controlling transmission of digitized media data in a packet switching network. When the processor receives a request from a network client node for presentation of specified media data stream presentation unit sequences the processor in response retrieves media data from a corresponding media access location, determines the media data type of each presentation unit in the retrieved media data, and designates each retrieved presentation unit to a specific media data presentation unit sequence based on the media data type determination for that presentation unit.

  • Patent number: 5197945
    Abstract: A wound dressing of alginate staple fibers has improved integrity when its fibers have been hydroentangled. Even when its basis weight is as low as 50 g/m.sup.2, the resulting wound dressing, when saturated with saline fluids, can be removed by forceps from a wound as a single piece, having little or no residue in the wound. At basis weights below 50 g/m.sup.2, the wound dressing preferably includes reinforcing fibers such as rayon.

  • Patent number: 4819159
    Abstract: The method and means of fault-tolerant processing includes a plurality of system building blocks, each including a real-time processor and specialized processors and local non-volatile memory that are coupled to communicate internally within each of the system building blocks, which, in turn, communicate with one another over local-area network links, and communicate with the remainder of the system over an I/O bus controlled by an I/O processor. Transaction-based processing is under control of a transaction coordinator which permits all of the transaction operations to complete successfully and then alter stored data for the completed transaction, or not to alter any stored data if a transaction is not completed. The transaction coordinator maintains a record of the distributed file accesses required during processing of a transaction, and prevents other transactions from altering stored data during processing of a transaction.

  • Patent number: 4414589
    Abstract: A servo track following system for positioning a moving read/write head relative to a magnetic storage disc. A plurality of servo tracks are recorded in sectors on the disc for identifying radial positions or informational tracks. The servo tracks have a nonuniform radial track density varying from more dense at the periphery of the disc to less dense at the interior, established with a method that allows the unique performance characteristics of the head to determine the actual spacing of the tracks. A clock track is written by writing a single pulse on a fixed clock track head, phase-lock looping to an intermediate clock track, which is written on a moving head, and then phase-lock looping up to the final clock track which is written on the fixed clock track head. Radial track density is then determined by moving a head to a limit stop and writing a reference track.

  • Patent number: 4223390
    Abstract: A system and method attach a second magnetic storage device to a storage subsystem which includes one or more first magnetic storage devices. The track capacity of the first device, i.e., the maximum number of bytes per track, is different from the track capacity of the second device. The information stored on the first device is formatted with a first recording format wherein the start of each individual record measured in the number of bytes from the start of the track varies with either the number of records preceding it, or the length of each preceding record, e.g., a count-key-and-data format.
