Abstract
A method for identifying an identification (ID) tag that includes at least one magnetically bistable element. The method comprises one or more steps, including transmitting, via an excitation antenna, an excitation signal to the magnetically bistable element. An additional step includes receiving, via a pick-up antenna, a response signal generated by the bistable element. An additional step includes analyzing the response signal to identify at least two peaks in the response signal. A further step includes generating an identification code based on the two peaks, with the identification code being representative of an identity of the bistable element.
Claims18
A method for identifying an identification (ID) tag that includes at least one magnetically bistable element, wherein the method comprises the following steps:
- (a) transmitting, via an excitation antenna, an excitation signal to the magnetically bistable element, wherein the excitation signal comprises a triangular wave;
- (b) receiving, via a pick-up antenna, a response signal generated by the bistable element;
- (c) analyzing the response signal to identify at least two peaks in the response signal;
- and
- (d) generating an identification code based on the two peaks, wherein the identification code is representative of an identity of the bistable element.
An identification system comprising:
- an excitation antenna configured to transmit an excitation signal to at least one magnetically bistable element, wherein the excitation signal comprises a triangular wave;
- a pick-up antenna configured to receive a response signal generated by the bistable element;
- and
- a computing device comprising a processing element and a memory element, and wherein the processing element is configured to perform the following steps—
- analyze the response signal to identify at least two peaks in the response signal;
- and
- generate an identification code based on the two peaks, wherein the identification code is representative of an identity of the bistable element.
