  • Method of forwarding channel assignments for one or more traffic channels
    Patent number: 6628953
    Abstract: A remote unit (101) monitors a control channel for a base station (103) and sends a probe message (301) to the base station (103). The base station (103) forwards the probe message with location information (305) to a controller (115). The controller (115) determines an approximate distance for the remote unit (101). Based on the approximate distance, the controller (115) determines at least one additional site. A channel assignment message (309 or 401) is forwarded to the remote unit (101), which message includes one or more traffic channels associated with at least one of the base station (103) and the at least one additional site.

  • Head-disk stiction reduction
    Publication number: 20030102218
    Abstract: Magnetic disk drive head/disk stiction is reduced by applying an electrostatic field between the head and the disk as the head dwells in contact with the disk surface. Just before the disk drive begins disk rotation in order that the heads take off, the electrostatic field is removed.

  • Magnetic recording medium utilizing patterned nanoparticle arrays
    Publication number: 20020034666
    Abstract: A method of patterning a layer of ferromagnetic metallic nanoparticles for use as a portion of a magnetic recording medium is provided. The method involves providing a substrate and coating the substrate with an unmodified affinity layer. Portions of the unmodified affinity layer are exposed to a reactive material that chemically modifies the affinity layer. The modified portions are chemically attractive to the nanoparticles. The nanoparticles are then deposited on the chemically modified portions of the affinity layer. A recording medium comprising a substrate, a modified affinity layer and a ferromagnetic nanoparticle metallic layer is also disclosed.

  • Method for extending the cell radius between a mobile station and a base station
    Patent number: 6192247
    Abstract: The present invention provides a method for extending the cell radius between a mobile station (101) and a base station (103). A propagation delay is determined between the mobile station (101) and the base station (103). A transmit time offset is determined for the mobile station (101). The transmit time offset is based at least in part upon the propagation delay. Information is then transmitted between the mobile station (101) and the base station (103) at the transmit time offset.
