  • Circuit arrangement that functions as an interface between a SIM card and GSM modem
    Patent number: 7627345
    Abstract: The present disclosure relates to a circuit arrangement and a method for defining the signal direction in a data line between the interfaces of a SIM card and a GSM modem, without a control signal for the direction of data and without remote access. According to the disclosure, the transmission direction of the data signals is detected and as a result only one direction is permitted for the transmission, whilst detection in the opposite direction is simultaneously blocked.
    Type: Grant
    Filed: September 9, 2003
    Date of Patent: December 1, 2009
    Assignee: Cinterion Wireless Modules GmbH

  • Power supply via data lines in local networks
    Publication number: 20060245449
    Abstract: A particularly space saving and cost effective apparatus and method for supplying power to terminals via data lines of a local network with the aid of a method and a device for supplying power from a current sink via two data line pairs of a local network. Decoupling and/or coupling of a supply voltage provided by a voltage source takes place between the central point of two voltage dividers that are arranged between the two data lines of a pair.

  • Method for transmission of audio signals
    Publication number: 20040044427
    Abstract: A method is provided for transmitting audio signals from at least one hi-fi signal source to at least one hi-fi signal sink, wherein the audio signals are compressed in the MP3 compression standard and then transmitted from the at least one hi-fi signal source to the at least one hi-fi signal sink via the Bluetooth radio standard and in a single Bluetooth radio channel.
