Abstract
En sikkerhets-merkelapp (50) for en CD-beholder (10) som inneholder en CD (12), består av et hovedsakelig flatt substrat (52) som omfatter kretser for å etablere en resonanskrets (62). Substratet (52) er plassert i CD-beholderen (10), slik at et første parti av substratet strekker seg utenfor omkretsen til CDen, og et andre parti av substratet overlapper i det minste en del av CDen. En del av kretsen (62) er plassert på hvert av de første og andre partier av substratet, slik at resonanskretsens (62) frekvens blir etablert i det minste delvis ved vekselvirkning mellom kretsene og CDen. Sikkerhets-merkelappen (50) blir brukt i et elektronisk sikkerhetssystem for et overvåket område, omfattende en sender for utsending av elektromagnetisk energi inn i det overvåkede område ved en forhåndsbestemt detekteringsfrekvens, og en mottaker for detektering av tilstedeværelsen av en sikkerhets-merkelapp som ved en detekteringsfre- kvens frembringer resonans i det overvåkede område.A security tag (50) for a CD container (10) containing a CD (12) consists of a substantially flat substrate (52) comprising circuits for establishing a resonant circuit (62). The substrate (52) is located in the CD container (10) such that a first portion of the substrate extends beyond the circumference of the CD and a second portion of the substrate overlaps at least a portion of the CD. A portion of the circuit (62) is located on each of the first and second portions of the substrate so that the frequency of the resonant circuit (62) is established at least in part by interaction between the circuits and the CD. The security tag (50) is used in an electronic security system for a monitored area, comprising a transmitter for transmitting electromagnetic energy into the monitored area at a predetermined detection frequency, and a receiver for detecting the presence of a security tag as a the detection frequency produces resonance in the monitored area.
