Title: Method and apparatus for performing soft hand-off in a wireless communication system
Inventor: PADOVANI ROBERTO
IPC: H04W36/18
Filed: 1998-01-27
Abstract: A method and apparatus for providing soft hand-off in a mobile communication system. In current systems, members of an active set of base stations (4, 4A, 4B, 4C) are determined by comparing measured pilot energy with fixed thresholds. The value of providing a redundant communication link to a mobile station (2) primarily depends on the energy of other signals being provided to the mobile station (2). In the present invention, the signal strength of each signal transmitted by other base stations (4, 4A, 4B, 4C) in communication with a mobile station (2) is considered when determining whether to add a base station to the set of base stations (4, 4A, 4B, 4C) in communication with the remote station. A base station is added only if the signal received from that base station provides sufficient added value to justify the impact on system capacity.

Title: System and method using adaptive antennas to selectively reuse common physical channel timeslots for dedicated channels
Inventor: ROY VINCENT
IPC: H04B17/00
Filed: 2004-02-10
Abstract: A method and communication system (e.g., TDD system) that uses adaptive antennas at the base stations to monitor metrics associated with the quality of one or more CPCH timeslots, so as to determine whether to reuse some or all of the CPCH timeslots to transmit the DPCH. If it is determined to reuse some or all of the CPCH timeslots, an additional determination is made as to what limit to apply on the DPCH transmission powers. Adaptive antennas may be used at the base stations to allow the system to reuse some or all of the CPCH timeslots to transmit DPCH, thus improving the overall capacity of the system while maintaining the CPCH coverage and quality at a desired level throughout the system.

Filed: 2004-01-21
Abstract: A clutch assembly 10 is provided for a motor having a shaft 36, a worm 40 associated with the shaft and an output gear 42 engaged by the worm. The clutch assembly includes a clutch body 12 having a plurality of pockets 22 in a surface thereof. Each pocket has a cam surface 24 defined by a depth of the pocket that gradually increases from a deep end to a shallow end. A ball bearing 18 is disposed in each of the pockets 22. Spring structure 16 is constructed and arranged to maintain the ball bearings in the pockets. A pressure plate 14 is operatively associated with the clutch body and is constructed and arranged to be coupled with the shaft 36 of the motor. The clutch assembly is constructed and arranged such that when the output gear 42 of the motor is driven in a certain direction by an external torque causing an axial force to be exerted on the worm 40 and thus inducing an axial movement and angular movement to the shaft, the pressure plate 14 comes into contact with the ball bearings 18 transferring the axial and angular movement to the ball bearings which in turn move up the cam surface towards the shallow end of each pocket until the ball bearings wedge between the pressure plate and surfaces defining the associated pocket, thereby preventing rotation of the shaft when coupled with the pressure plate.
