  • Patent number: 7925277
    Abstract: The invention provides a positioning system of positioning a wireless communication apparatus. The positioning system transmits and receives positioning signals which have different frequency bands and generates corresponding positioning values according to the positioning signals. The positioning system then judges and selects positioning values which have less error from the generated positioning values, and calculates an average value of the selected positioning values. Therefore, positioning of the wireless communication apparatus will be more precise. Furthermore, if the positioning system is implemented in a radio-wave-based wireless communication environment, the N positioning signals can be polarized in a linear polarization way, a left-handed circular polarization way or a right-handed circular polarization way, so as to reduce the environmental impact to enhance precision of the positioning.

  • Patent number: 7920852
    Abstract: A remote wireless device receives a compressed message including an application definition file. The application definition file is associated with an application executing at a computing device and contains definitions for: a user interface format; a format for network messages; and a format for storing data. Using these definitions, the wireless device may receive data generated by the application and formatted in accordance with the definitions. The wireless device may then present a user interface for the application. Preferably, the application definition file is an XML file. Similarly, application-specific network messages provided to the device are also formed using XML. Data generated by the application may be presented at the mobile device under control of a virtual machine that uses the application definition file. For efficiency, the network messages received at, and transmitted by, the wireless device may be compressed.

  • Patent number: 7904083
    Abstract: A method and apparatus for efficient network scanning that selects candidate frequencies based upon the frequency bands that were noted as being active during a previous network scan. A mobile device performs a full network scan on power up or on radio cycle and determines the available active bands. This information is stored as active band information on the device. When the device loses coverage on a selected one of the bands, then it identifies a candidate frequency based upon the stored active band information and attempts to locate a suitable network on the candidate band.
