Abstract
A data carrier (1) for the transmission of transmission data (UD) to a base station over a transmission time range (TT) containing load time ranges (TA) and load relief time ranges (TB0, TB1) comprises cut-off means (13) which, once activated, set principal power consumers (10, 12) of the data carrier (1) into an energy-saving operating condition for a cut-off time range containing the load time range (TA), so that the storage capacitor (9) for operation of the passive data carrier (1) over the load time ranges (TA) may advantageously have only a relatively low capacitance.

10. The method of transmitting transmission data (UD) from a data carrier (1) to a base station over a transmission time range (TT) comprising load time ranges (TA) and load relief time ranges (TB0, TB1), the method comprising the following stages:
-
reception of a carrier signal (TS) from an electromagnetic carrier field (HF);
generation and storage of a DC power (UB) from the received carrier signal (TS), said DC power (UB) being used for operation of the passive data carrier (1);
processing and output of the transmission data (UD) to be transmitted;
transmission of the transmission data (UD) to the base station over the transmission time range (TT), the electromagnetic carrier field (HF) being subjected to a load (6) over the load time ranges (TA), so that over the load time ranges (TA) the amplitude of the received carrier signal (TS) is essentially less than over the load relief time ranges (TB0, TB1), and the data carrier (1) being operated over the load time ranges (TA) essentially by means of the stored DC power (UB), characterized in that at least one power consumer (10, 12) of the data carrier (1) is deactivated at a cut-off time (tA1, tA2) fixed immediately prior to or at the start of each load time range (TA), and that the deactivated power consumer (10, 12) is reactivated once a cut-off time range (TA) following the cut-off time (tA1, tA2) has elapsed. - View Dependent Claims (11)
