  • Executing program to protected memory in transponder using wireless base station
    Patent number: 9063890
    Abstract: An apparatus and a method is provided for the execution of a program by a program-controlled device, in which the program-controlled device receives instructions and automatically executes the program if it receives an access instruction for accessing a protected memory area. The invention further relates to a programmable transponder containing at least one such program-controlled device.
    Type: Grant

  • Process for the transfer of data
    Patent number: 6882826
    Abstract: In a process for the transfer of data between a base station and a transponder by an electromagnetic carrier wave, on which data bits are modulated by amplitude modulation, the duration of a modulation interval of a data bit is determined and compared with a reference value, a correction value is calculated from the deviation of the actual value of the duration of the modulation interval from the reference value, and the actual values of the duration of the modulation intervals of the following data bits are corrected with the correction time. As a result of the correction, the duration of the modulation intervals may be reduced and the data transfer rate increased or the transfer rate may be adapted to the transfer conditions.
