  • Patent number: 7886311
    Abstract: A hardware-independent proxy layer for synchronous processing of commands in a mobile telephone is disclosed. Such synchronous processing may include receiving a function call of an application program interface (API) that is associated with a function to be performed by a mobile telephone, waiting to receive from a driver layer a result notify event indicating that the function has been performed, and, after receiving the result notify event from the driver layer, passing to the client first result data associated with the first result notify event. The API may be translated into an input/output control (IOCTL) code, which may be sent to the driver layer.

  • Publication number: 20110026921
    Abstract: Systems and methods for transferring incoming single-ended burst signals of which at least one characteristic varies widely from burst to burst onto a pair of differential lines. The systems comprise an input for receiving an incoming burst signal, a signal adaptation block for adapting said widely varying characteristic and a single-ended-to-differential converter. In a first aspect a reset signal for resetting a settings determination block, which controls the signal adaptation block, is sent backwards over the differential lines, preferably using a common-mode signal. In a second aspect, a status freezing mechanism is employed for freezing the settings of the settings determination block after the end of the preamble of an incoming burst.
