  • Patent number: 8144664
    Abstract: A method and apparatus for performing a serving high speed downlink shared channel (HS-DSCH) cell change from a source cell to a target cell are disclosed. A radio network controller (RNC) may pre-load a wireless transmit/receive unit (WTRU) with HS-DSCH configuration for the target cell. The WTRU receives and stores the pre-loaded HS-DSCH configuration. The WTRU may start monitoring a high speed shared control channel (HS-SCCH) on the target cell using the pre-loaded HS-DSCH configuration for the target cell on a condition that a measurement report is triggered by the event 1D. The WTRU may initiate a timer when the WTRU starts monitoring the HS-SCCH on the target cell and stop monitoring the HS-SCCH on the target cell upon expiry of the timer.

  • Patent number: 8143849
    Abstract: A method and system for recharging a battery power supply unit is provided. During the recharging of a battery power supply unit for a bicycle electronic device, the power supply unit is electrically disconnected from the electronic device and receives recharging energy from a first power supply circuit of a battery charger. The battery charger comprises a second power supply circuit which, during the recharging of the battery power supply unit, supplies the electronic device. In such a manner, the first power supply circuit is intended only for recharging the battery power unit and the recharging is hence optimized.

  • Patent number: 8145253
    Abstract: A method and apparatus for performing state transition of a wireless transmit/receive unit (WTRU) which supports enhanced dedicated channel (E-DCH) in the CELL_FACH state is disclosed. Uplink data is transmitted via an E-DCH while operating in a CELL_FACH state. A radio resource control (RRC) signal, which includes a reconfiguration message, is received while the WTRU is assigned an E-DCH resource. A reconfiguration of the physical channels is performed according to the RRC reconfiguration message. A transition to a CELL_DCH state is performed and uplink data is transmitted in the CELL_DCH state via the E-DCH. In-synch and out-of-synch parameters are reported.

  • Patent number: 8144064
    Abstract: A narrow band, tunable antenna uses a series of small inductors wired in series to produce different resonant frequencies from a single antenna across a wide frequency spectrum. Radio Frequency (RF) switches are positioned in parallel with the inductors and are capable of shunting a selected inductor out of the antenna circuit thereby changing the electrical length of the antenna and consequently, the resonant frequency. The RF switch control circuitry is isolated from the RF current in the antenna.

  • Patent number: 8141527
    Abstract: A camshaft adjuster (1) having a variable ratio gear unit (2). Usually, a drive movement of an electrical actuating assembly (7) is transmitted into a variable ratio gear unit (2) of a camshaft adjuster (1) on the side which faces away from the camshaft (6). According to the invention, the abovementioned drive movement is transmitted in from the side of the variable ratio gear unit (2) which faces the camshaft (6). As a result, a further assembly, for example a vacuum pump, can be driven by the variable ratio gear unit (2) on the side of the variable ratio gear unit (2) which has become free and faces away from the camshaft (6). An actuating shaft (4) of the actuating assembly (7) is preferably mounted via a bearing (34) which is supported on a circumferential face of the camshaft (6). This results in a reduced axial overall size of the camshaft adjuster and extended possibilities for the arrangement of an actuating assembly and the connection of additional assemblies.

  • Patent number: 8142390
    Abstract: A syringe device (1) with an elongate plunger space (2), a receiving chamber (3) for receiving solid medicaments (4), and a hollow needle (5) arranged in the plunger space (2), and also a plunger (7) which is suitable for movement in the plunger space (2) and bears a ram (8) for pushing out the solid medicament (4). For displacement of the plunger (7) there is a plunger rod (9) which acts thereon and, for its use, can be extended telescopically out of the plunger space (2) and relative to the plunger (7) and can be coupled to the plunger by means of a lock (10). The locking of the plunger (7) to the plunger space (2) is opened or released only by complete withdrawal of the plunger rod (9) in its operative position while at the same time the plunger rod (9) is coupled to the plunger (7) in this position in the pushing direction such that the medicament can then be pushed out.

  • Patent number: 8139609
    Abstract: A method and apparatus for segmenting medium access control (MAC) service data units (SDUs) creates enhanced MAC-es PDUs in the enhanced MAC-e/es sub-layer by concatenating MAC SDUs received from the logical channels. An enhanced transport format combination (E-TFC) selection entity controls the concatenation of MAC SDUs into enhanced MAC-es PDUs. When a MAC SDU is received that is too large to fit into a selected enhanced MAC-es PDU payload, a segmentation entity segments the MAC SDU such that the MAC SDU segment fills the remaining payload available in the selected enhanced MAC-es PDU. The enhanced MAC-es PDU is then assigned a transmission sequence number (TSN) and multiplexed with other enhanced MAC-es PDUs to create a single enhanced MAC-e PDU that is transmitted on the E-DCH in the next transmission time interval (TTI). A HARQ entity stores and, if necessary retransmits the enhanced MAC-e PDU when a transmission error occurs.

  • Patent number: 8137598
    Abstract: A spreader box and method form a bi-laminar paintball shell material. Walls of a box body define a reservoir containing, and an aperture dispensing, a first gel. Walls of a gate body define a reservoir containing, and an aperture dispensing, a second gel. Within the box, the first gel is kept separate from the second gel. The box body aperture dispenses the first gel as a continuous first layer. The gate body aperture dispenses the second gel as a continuous second layer that is adjacent and juxtaposed with the first layer, such that the first gel bonds with the second gel to form the bi-laminar paintball shell material. A paintball, containing a fill material, has a frangible bi-laminar shell including an exterior shell that completely surrounds and contains an interior shell. The paintball is adapted to withstand the normal range of forces sustained in being fired from a paintball gun.

  • Patent number: 8136790
    Abstract: An electromagnetic actuator for a hydraulic directional control valve is provided. The electromagnetic actuator is used for adjusting a hydraulic directional control valve, for example, for the variable adjustment of the control times of an internal combustion engine. The electromagnetic actuator includes a housing (08) with which the electromagnetic actuator is mounted opposite the hydraulic directional control valve. The electromagnetic actuator further includes a coil (01) that is arranged in a coil body (03). The electromagnetic field that can be generated with the coil (01) acts on an armature (09) that is arranged in the electromagnetic actuator so that it can move axially. In order to prevent that the hydraulic medium of the hydraulic directional control valve leaks from reaching the electromagnetic actuator, the actuator includes a seal (13; 24) between the coil body (03) and the housing (08). The coil body has a holder (26, 28) for holding the seal (24).
