RESONANCE MARKING DEVICE WITH REMOTE SUPPRESSION Russian patent published in 1995 - IPC

FIELD: radio electronic systems for prevention of unauthorized movement of objects beyond limits of guarded zone. SUBSTANCE: resonance marking device includes dielectric substrate 1 which one side carries induction coil 2 connected with one end to fusible conductor 9 with two-wire quarter-wavelength resonator 7 and with other end to plate 3 of capacitor which second plate is arranged on reverse side of substrate 1 and is linked to second fusible conductor with second two-wire quarter-wavelength resonator. Device is inserted with second capacitor which plate 5 is linked to fusible conductor 9 and which other plate is arranged on reverse side of dielectric substrate and is connected to second fusible conductor. EFFECT: simplified design of electron mark with simultaneous time reduction of technological process. 3 dwg
