  • Publication number: 20110273327
    Abstract: A data model containing orbital parameters is stored in a mobile device. When a First Fix is required by a GNSS system within the mobile device, these stored orbital parameters are used to rapidly generate accurate satellite trajectory data model. The stored orbital parameters may be modified in part or in whole as required by changing coefficients of the stored parameters.

  • Publication number: 20110273329
    Abstract: A data model is built using satellite ephemeris data collected over an extended period of time, allowing generation on a server of very precise orbital parameters preferably using a force or numerical method. These orbital parameters are stored in a mobile device. When a First Fix is required by a GNSS system within the mobile device, these stored orbital parameters are used to rapidly generate accurate satellite trajectory data model without requiring access to a broadcasted ephemeris or a network connection. The stored orbital parameters may be modified in part or in whole as required by changing coefficients of the stored parameters.

  • Publication number: 20110174098
    Abstract: In one aspect, a cradle system for supporting a load, the cradle system comprising a first arm with a first carriage assembly axially adjustable therealong and a second arm, opposite the first arm, with a second carriage assembly axially adjustable therealong. An actuator is associated with the first and second carriage assemblies and configured such that actuation of the actuator causes the first and second carriage assemblies to move axially in opposite directions. In another aspect, a cable support system comprising a support column and one or more tethers supported by the support column and configurable so that at least one tether is configured to move its supported cable in the same or opposite direction as the test head moves at a rate that is a constant multiplied by the test heads rate of motion where the constant may be greater than, equal to, or less than one.

  • Publication number: 20110136448
    Abstract: An uplink power control technique may include a simplified maximum sector throughput (SMST) and a generalized maximum sector throughput (GMST). The SMST and GMST techniques may be used to determine a maximum sector throughput and cell-edge throughput to enhance the overall efficiency of the communication system. The uplink power control technique may determine the optimal uplink power value without collecting interference over thermal noise and without computing the individual channel losses in each neighboring sector.

  • Publication number: 20110057674
    Abstract: A test head manipulator system comprising a base structure, a main arm unit configured to support a test head and to be moved relative to the base structure, an actuator having a range of motion of L, and an enhancement mechanism positioned between the main arm unit and the actuator and configured such that movement of the actuator a first distance causes the main arm unit to move a second distance that is greater than the first distance. Additionally, a fluid control system for controlling a test head manipulator system. The pneumatic control system includes a regulator configured to controllably provide an output pressure to the main fluid actuator, and a second fluidly controlled actuator configured to adjust the regulator to modify the output pressure provided to the main fluid actuator. The second actuator is configured to be positively positioned in at least four operating modes with each operating mode causing the regulator to provide a different output pressure to the main fluid actuator.

  • Publication number: 20100234059
    Abstract: A channel normally used to transmit acknowledgement of successful signal receipt and an indication of unsuccessful signal receipt is adopted to transmit power control information from a base station to a mobile station. The power control information can be encoded as a binary code where each value of the code is indicated by an acknowledgement or non-acknowledgement signal.

  • Patent number: 7784028
    Abstract: A method for multi-standard Software defined radio (SDR) base-band processing is provided. The method comprises the steps of: constituting SDR software framework, which includes SDR kernel structure, SDR software modules, other application parts and an operating system; extracting protocol software modules of different standards and reclassifying them as dedicated system libraries, common system libraries and common algorithm libraries, and then storing them into the software modules; adding a scheduler to the SDR kernel structure, the scheduler structuring a concrete base-band application software module by the dedicated system libraries, common system libraries and common algorithm libraries, using Process and Sequence; and, defining SDR hardware platform, applying the concrete base-band application software which is structured by the scheduler on the SDR hardware platform, so as to complete concrete base-band processing of the wireless communication system.

  • Publication number: 20100203917
    Abstract: Techniques are described that can be used to determine a transmitter power level of a mobile station based on spectrum efficiency gain and loss. Spectrum efficiency gain is measured for a home sector base station. Spectrum efficiency loss is measured for base stations other than the home sector base station. In one example, a base station transmits information such as noise plus interference level to a mobile station and the mobile station determines the transmitter power level. In another example, the mobile station transmits information such as preamble signal strength and preamble total signal strength to the home sector base station and the home sector base station determines the transmitter power level and instructs the mobile station to apply the determined transmitter power level.

  • Publication number: 20100180265
    Abstract: A firmware extension method is provided, particularly adaptable for an embedded system. Firstly, a baseline firmware image is provided with a header file. Secondly, an extension firmware image is generated based on the header file, comprising one or more extended functions. Thereafter, a callback table is generated, comprising pointers pointing to entries of the extended functions in the extension firmware image. The baseline firmware image, the extension firmware image and the callback table are then merged to generate a merged firmware image.

  • Patent number: 7590616
    Abstract: Methods and apparatus for a recommendation system based on collaborative filtering is provided. Explicit and implicit ratings of items by network users are used to create a contextual model. The explicit ratings comprise different rating types regarding different item attributes. The implicit ratings comprise different rating types derived from different user events and may include recency, intensity, or frequency ratings. The contextual model may be optimized for a specific objective function, such as click-through-rate or conversion rate. In other embodiments, item information is used to produce a content model where item information for an item is encoded as metadata into a document that represents the item. The contextual or content model is used to recommend one or more items to a current user. The basic unit of the recommendation system may be an item set of two or more items or a particular sequence of two or more items.
