INDICATOR LABEL Russian patent published in 2010 - IPC G09F9/00 

FIELD: physics.

SUBSTANCE: indicator label is used distributive industries, in storage, transportation of goods, in systems for controlling supply of materials and machinery and systems for controlling quality of products. The indicator label is a combination unit and includes one or more light indicators and/or micro-displays with resonant circuits and a semiconductor circuit. A symbol identifier detector consists of a top active magnetic layer and a bottom passive magnetic layer, which are made from magnetic powder and/or magnetic pigment with constant magnetic characteristics during a given time interval relative a given damping rate during a given time interval for one of the characteristics, transmitted by the antenna of the resonant circuit of the semiconductor circuit. Each reflecting layer of the micro-display is made from metal particles or blocks of glass microspheres which lie in the region where communication antennae of the resonant circuit are located. The resonant circuit has resonant frequency equal to the sum of two different modulation frequencies of the radiation of the active radio-frequency emitter of the semiconductor circuit.

EFFECT: proposed indicator label is cheap to make, easy to use and provides high degree of controlling quality of a product.
