  • Patent number: 7433310
    Abstract: A method for determining whether a connection event between a base station and a wireless transmit/receive unit (WTRU) should be accepted or rejected, comprises measuring the interference level I0 in a candidate timeslot; measuring the path loss L between the base station and the WTRU; measuring the total transmit power P0 of the base station; determining a thermal noise level ?, determining a fading average signal-to-interference ratio (SIR); and calculating a ratio R, wherein if the ratio R is above a certain threshold the connection event will be accepted and if the call is below the threshold it will be rejected.

  • Patent number: 7432635
    Abstract: A driving device in a lens barrel unit of a lens unit drives advancing/retreating of a lens frame holding a lens, and manual focusing. The lens frame is supported freely movably back and forth by an internal driving ring turned and driven when automatic focusing. The internal driving ring is supported by a distance ring so as to be turned and driven via an external driving ring supported turnably by a fixing frame. An operating ring is fixed on the perimeter of the distance ring, and manual focusing driving is performed by turning the operating ring. A transducer of an ultrasonic actuator is pressed against the end face of the distance ring via a driver, frictional contact force between the distance ring and the driver is adjusted by applying flexion standing wave vibration to the transducer, and the amount of turning operating force of the operating ring can be increased/decreased over a wide range.

  • Patent number: 7430185
    Abstract: A system and method which permit the RNC to control purging of data buffered in the Node B. The RNC monitors for a triggering event, which initiates the purging process. The RNC then informs the Node B of the need to purge data by transmitting a purge command, which prompts the Node B to delete at least a portion of buffered data. The purge command can include instructions for the Node B to purge all data for a particular UE, data in one or several user priority transmission queues or in one or more logical channels in the Node B, depending upon the particular data purge triggering event realized in the RNC.

  • Patent number: 7428899
    Abstract: The invention relates to a device for feeding ball-like ammunition, so-called paint balls, into the projectile chamber of a sporting arm. The magazine is arranged separately from the arm and is connected to same by means of a feeder tube. A motor-driven feeder feeds the balls from the ball container into the feeder tube. In so doing, a spring element stores the traction from the motor, so that, even when the motor stops, balls can still be transported using the energy stored in the spring element. The traction from the motor is transmitted via a connection or clutch consisting of a spring element and a transmission element. Protrusions are arranged on both the spring element and the transmission element, which come to bear on each other for transmitting traction. The protrusions are at least partially flexible, so that the transmitted force is limited. This way, explosion of the balls from excessive pressure is prevented.

  • Patent number: 7426944
    Abstract: Double layer forming fabrics, woven to an overall repeating weave pattern requiring at least 8 sheds in the loom, provide a low drainage area in a notional center plane between the paper and machine side layers, to resist and retard initial impingement drainage. Transverse binder yarn pairs follow a single combined path interweaving with paper side layer and machine side layer yarns, with long internal floats under at least four paper side layer yarns between exchange points and interlacing points in the machine side layer. The members of the pairs are laterally displaced in relation to each other along the single combined path. The fabric has a total warp fill after heatsetting of at least 100%. The drainage areas of the paper side layer and the machine side layers are between 25% and 50%, and the center plane drainage area is between 8% and 20%.

  • Patent number: 7427953
    Abstract: A wireless communication method and antenna system for determining the direction of arrival (DOA) of received signals in azimuth and elevation, (i.e., in three dimensions), to form a beam for transmitting and receiving signals. The system includes two antenna arrays, each having a plurality of antenna elements, two first stage multi-mode-port matrices, at least one second stage multi-mode-port matrix, an azimuth phase detector, an elevation amplitude detector, a plurality of phase shifters and a transceiver. The antenna arrays and the first stage multi-mode-port matrices form a plurality of orthogonal omni-directional modes. Each of the modes has a characteristic phase set. Two of the modes' phases are used to determine DOA in azimuth. The second stage multi-mode-port matrix forms a sum-mode and a difference-mode used to determine the DOA of the received signals in elevation. A beam is formed in the direction of the received signals by adjusting the phase shifters.

  • Patent number: 7428425
    Abstract: A criterion for biasing a binary decision requiring an unequal protection which utilizes a measured signal to interference ratio (SIR). The SIR may be derived from a determination of channel estimation. The SIR is compared against a threshold, the threshold being selected to bias the decision toward a NACK as opposed to an ACK determination. The technique is advantageous for providing biased binary decisions for high speed downlink packets (HSDP) but may be utilized for both uplink and downlink applications.

  • Patent number: 7428279
    Abstract: A sliding window based data estimation is performed. An error is introduced in the data estimation due to the communication model modeling the relationship between the transmitted and received signals. To compensate for an error in the estimated data, the data that was estimated in a previous sliding window step or terms that would otherwise be truncated as noise are used. These techniques allow for the data to be truncated prior to further processing reducing the data of the window.
