INDICATING LABEL

摘要

The inventive indicating label "Globe " is a combined device and comprises one or several colour indicators and /or micro-displays provided with resonance circuits and a semiconductor circuit. The indicator is also provided with a symbol identifier sensor in which magnetic powder and/or magnetic pigment of layers exhibits permanent magnetic characteristics for a specified time interval with respect to the rate of decay of one of the characteristics transmitted by the resonance circuit antenna of the semiconductor circuit during the specified time interval. Each reflecting layer of the micro-display is made of metal particles or blocks of glass micro-spheres which are located in the area of the communications antennas of the resonance circuit. The resonance frequency of the resonance circuit is equal to the sum of two different modulation frequencies of a radiation emitted by the active radiofrequency emitter of the semiconductor circuit.
