US 8,284,030 B2 · Method and device for recognizing functional states in RFID or remote sensor systems

Abstract

A method for recognizing time-variable functional states, e.g., in the course of a programming process, in RFID systems is disclosed, which includes at least one transponder or remote sensor and at least one base station, which transmits data and/or power to the transponder or sensor by a carrier signal. According to the invention, after a specified process state is attained at least one confirmation symbol is transmitted by the transponder or sensor to the base station. As a result, no unfavorable “worst case” scenario has to be provided for chronologically controlling time-variable processes because the base station is able to clearly recognize the beginning and end of the process, as well as the state thereof. RFID systems or remote sensor systems can thus be controlled more quickly and more reliably, resulting especially in reduced costs.

Claims20

Dependent claims

A method comprising:

receiving from a base station a data transmission comprising a carrier signal having a time reference;
initiating, in response to receiving the time reference of the data transmission, a programming process of a memory of a transponder, the programming process programming the memory of the transponder according to the data transmission;
and
transmitting, based on a state of the programming process of the memory of the transponder, a confirmation symbol to the base station.
