Abstract
In a method and apparatus for encoding a tag with an n-bit binary code one or more predetermined frequency sources are associated with the tag that produce known different respective characteristic frequencies, each of which is associated with a known unique position in the n-bit binary code,
Claims6
A method for decoding an n-bit binary code encoded by a tag having associated therewith one or more predetermined frequency sources each adapted to emit a respective characteristic frequency associated with a known unique position in the n-bit binary code, the method comprising:
- (a) detecting characteristic frequencies emitted by the tag;
- and
- (b) substituting at respective positions of said n-bit binary string respective binary values according to a presence or absence of the respective characteristic frequency associated with the respective position in the n-bit binary code.
A decoder for decoding a tag having an n-bit binary code, said decoder comprising:
- a decoding unit responsive to one or more different characteristic frequencies each of which is associated with a known unique position in the n-bit binary code and for substituting at respective positions of said n-bit binary code respective binary values according to a presence or absence of the respective characteristic frequency associated with the respective position in the n-bit binary code.
