Abstract
Official abstract text for this publication.
One example is directed to a reader device having a first resonance circuit and being configured to interrogate one or more other remotely-located resonance circuits, each associated with a second resonance circuit which may be part of a passive sensor circuit. The first resonance circuit is operated to cause the inductively-coupled oscillating signal to be swept over a range of frequencies and therein cause a jump or sudden transition in a frequency of the oscillating signal while the first and second resonance circuits are in sufficient proximity for inductively-coupling via an oscillating signal via their respective resonance circuits. Sensing circuitry may be used to detect the jump or sudden transition in the frequency of the oscillating signal and, by way of or in response to an indication of timing and/or a set of inductively-related parameters, data is conveyed from the sensor to the reader device via the inductively-coupled oscillating signal.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: a first resonance circuit, a second resonance circuit, and inductive-coupling circuitry respectively associated with the first and second resonance circuits to cause an inductively-coupled oscillating signal to be swept over a range of frequencies and, in response, to cause a jump or sudden transition in a frequency of an oscillating signal while the first and second resonance circuits are inductively-coupled; and a data communicat…
