    摘要: A method may include generating by a transponder a first code and transmitting the first code to a base station. The base station may generate first transmission information, encoding a base station code with a first identification and a first random number code, and may transmit the first transmission information to the transponder. The transponder may extract the base station code. A second code may be generated by the transponder and transmitted to the base station upon an associated request from the base station. Before transmission to the base station, the second code may be encoded with the extracted base station code. Second encoded transmission information comprising a second identification may be generated by the base station using the second code and transmitted to the transponder. A memory region of the transponder may be released for read and/or write access after the second identification was verified as valid.

    摘要: A data structure is provided for preventing access, in a computer system, to a data object having an identifier (ID). The data structure comprises a first lock object, in which the ID of the data object is stored, and in which a link to a storage location of the data object is assigned to the ID, and a second lock object, in which the ID of the data object is stored. In one embodiment, the ID is stored in the second lock object before storing the ID in the first lock object or before assigning the storage location of the data object to the ID in first lock object. Further, the ID is deleted from the second lock object after storing the ID in the first lock object or after assigning the storage location of the data object to the ID in the first lock object. The data object may be accessible by a software application, whereby the access of the software application to the data object is prevented if the ID is stored in the first or second lock object.

According to the invention, each antenna arm has an arm length along the arm, which is selected so that one of the series resonance frequencies of the antenna is below the operating frequency range and the next higher parallel resonance frequency of the antenna is above the operating frequency range. The invention relates furthermore to a backscatter-based RFID transponder with an antenna of this type.

    摘要: A transponder receives its operating energy from an external source such as a radio signal or a battery. Such transponders are used for example in a vehicle or in a remote sensor. The response range of the transponder is increased by converting the received energy into an operating voltage which in turn is used to generate a function voltage required for performing a current function sequence. The generated function voltage is checked to determine at least one characteristic of the generated function voltage. The determined function voltage characteristic, for example a voltage value directly representing the function voltage, is then used to acknowledge or reject a result of performing the function sequence. Thus, the time duration for performing any current function sequence is flexibly adapted to the current requirements of that function sequence, whereby the power consumption of the transponder is optimally reduced and the response range respectively increased.
