  • Publication number: 20140140435
    Abstract: Embodiments of the present invention disclose a transmit diversity method, a related device, and a system, which mainly includes: configuring two different antenna ports separately for different antennas in a network, so that the antennas can use transmit diversity based on the configured antenna ports. In one aspect, because two antenna ports are used in the network to perform transmit diversity, a diversity gain of multiple antennas is obtained. In another aspect, a cavity position caused by a completely identical precoding codebook used in the network is avoided, and therefore network communication performance is improved. The technical solutions according to the embodiments of the present invention efficiently use the transmit diversity of the multiple antennas to acquire diversity gain so as to improve network communication performance.

  • Patent number: 8693363
    Abstract: Systems (100, 200) and methods for providing TDMA communication. The methods involve determining a channel quality of an uplink channel. A communication delay is set equal to an integer value “K”. “K” is selected based on the channel quality. “K”?“N”. “N” is a total number of frames of a time slot of a TDMA signal (400). Thereafter, First Message Data (FMD) is communicated over the uplink channel in a first time slot (A1) of an uplink signal (1000, 1100, 1200, 1400, 1500, 1600). An Error Control Process (ECP) is performed using FMD to at least identify First Error Free Message Data (FEFMD). Filler data and/or at least a portion of FEFMD is communicated over a downlink channel in a last “N?K” frames of a time slot (A1) of a downlink signal (1050, 1150, 1250, 1450, 1550, 1650), when “K”<“N”.

  • Patent number: 8629368
    Abstract: A direct-metal deposition (DMD) processing stage and a 5DOF (degree of freedom) dry micro-EDM (mEDM) stage are integrated to provide the submicron scale resolution necessary for the ultra-precision processing of work pieces. The DMD processing stage includes optical feedback for dimensional control utilizing a high-power, fiber-coupled diode laser with fast response time and small beam parameter product. The electrical discharge machining (EDM) stage is a dry EDM stage using an inert gas with appropriate dielectric properties to perform the surface finishing operations. The system further includes one or more surface treatment operations to obtain a desired level of surface hardness or wear resistance and/or to minimize the distortion induced in treating the surface.

  • Patent number: 8401543
    Abstract: An apparatus, system and method are provided for testing a battery-powered electronic device-under-test in a transport frame engaged with a test fixture. A transport frame power supply is arranged to provide power to the DUT in a pre-testing stage. A switching circuit is arranged to switch from the transport frame power supply to a test fixture power supply in response to receiving a power switching signal indicating satisfaction of a pre-testing condition. Power from the test fixture power supply can then be switched back to the first transport frame, or to a second transport frame, to begin testing a second DUT. The ability to start a DUT test without having to wait for the DUT to boot-up in the test fixture reduces test time and increases efficiency of use of test equipment.

  • Publication number: 20110246385
    Abstract: Methods, computer readable media, and apparatuses for automatically recalibrating risk models are presented. An identifier of a modeling function may be received. The modeling function may have at least one input variable and a first set of one or more coefficients. Updated performance data that includes at least one input value corresponding to the at least one input variable may be received from a data source. Then, a second set of one or more coefficients may be calculated for the modeling function based on the updated performance data. If it is subsequently determined that the modeling function more accurately models the updated performance data when the second set of one or more coefficients is used in computing a result of the modeling function, then the first set of one or more coefficients may be replaced with the second set of one or more coefficients to recalibrate the modeling function.
