Description of the Invention (,) The present invention relates to a battery-less interrogator circuit for use in electronic commodity surveillance systems (EAS systems) Typically, the electronic card is configured in a label that is detected and affixed to the product by the E AS system to prevent unauthorized removal of the product from the store where the system is installed. E AS systems are usually installed in clothing, books, medicines, audio equipment, home appliances, and some music retail outlets to prevent unauthorized removal of such goods from there. Typically, these systems include one or more Transmitters and detectors at the customer's entry / exit point at the retail store in the form of a base β These bases emit a signal to a tag internally equipped with a transponder circuit, and the label is pseudo-adhesive to the product . The interrogator circuit responds to the transmitted magnetic signal by re-transmitting a second signal, wherein the second signal is falsely detected by the bases, thereby triggering an alarm bell to indicate an attempt to remove the merchandise without authorization. The labels can be affixed to the product permanently or removably. At the point of sale of the product, the label is either removed from the product or deactivated, if the label is permanently attached to it. EAS tags and strips are designed with different operating parameters, and the main systems currently used are frequency division (SF), radio frequency (UF), magneto-acoustic (ΑΗ), and wave frequency (HF). Electromagnetic type (EM). The present invention mainly relates to a transponder circuit, which can be incorporated into a label used in the SF and EM systems, wherein the label is removably adhered to the product, making it It can be reused after being removed from it. In the SF and EM systems, an alternating magnetic field is pseudo-emitted between the bases, and the tag is typically configured with a transponder circuit, where the transponder circuit In its simplest form, it includes a paired electrical and / or magnetic ground coupling -3-This paper is scaled to the Chinese storehouse rate (C; NS ,.

V. Description of the invention (>) The combined LC resonance circuit causes the second resonance circuit to re-transmit a signal different from the frequency emitted by these bases. Perhaps when the product passes between the bases, the base detects an activated label on the product. Important considerations in the design of the bases and labels of any EAS system are the "pickup rate" of the pseudo system. That is, the percentage of tags that move between the bases to activate the system is as high as possible, and the undetected tags that pass between the bases cause unauthorized removal of the goods to which the tags are attached. ^ Within the retail office where the EAS system is installed, the labels that can be adhered to a large number of goods have an essential element, that is, the labels are pseudo-non-expensive, and therefore the inclusion of complex interrogator circuits is excluded, Or exclude the configuration of the transponder circuit of the battery power supply. The fact that many currently used EAS systems have pick-up rates below approximately 100% (065% -70% vulgar) is false when the tag passes through the launch / detection As a result, the signal retransmitted by the transponder circuit is relatively weak; moreover, the signal retransmitted by the transponder circuit must be sufficiently strong to induce a current in the base forming the bases. Detection circuit In the case of the inductive coil, if the tag cannot occur, the label will escape the detection and the product to which the label is attached can be removed without authorization. A wide variety of transponder circuits are used in today's EAS tags, but There are roughly two types of resonant circuits, including at least one inductor in each circuit, and a reactance element, so that the impedance of the entire circuit is minimized at a special frequency. In addition, the size of the inductive and reactive elements of each circuit is pseudo Specially selected so that one of the interrogator resonance circuits resonates at a first frequency equal to the frequency of the magnetic signal emitted by the bases.

Description of the invention (4) The first circuit is connected When a signal is at a relevant frequency, the second circuit as a whole resonates at a second frequency using magnetic and / or electrical coupling that may be present in the transponder circuit. The second frequency is usually the Half of the first frequency. Although not necessary, the inductors of the first and second resonance circuits are usually arranged on the core of the ferromagnetic material to enhance mutual coupling therebetween, and the electric power of each inductor is shifted by the inductor coil, so that the core is only partially The ground is filled with the ferromagnetic core and changes (hence the transponder circuit as a whole is & humorous, _). When the inductive coils of the first and second resonant circuits are magnetically coupled in this way, there is usually a mathematical limitation on the mutual coupling of these components, while a circuit that is too effective to mutually couple will fail to retransmit the second And not at the frequencies emitted by those bases. Furthermore, it must be pointed out that some resonant circuits are more sensitive, which makes it more difficult to tune as the mutual coupling between them increases. For others, the mutual feeding of the resonance circuits between the coils affects the resonance frequency of each of these resonance circuits, because the mutual inductance between the coils will be reflected as the additional impedance of each resonance circuit, and at the same time, the configuration of the inductance coils The degree to which the two cores are connected to the ferromagnetic core can affect both the mutual inductance between the coils and the self inductance value in the resonance circuit. Therefore, the ferromagnetic core contains a resolvable interrogator circuit which has the ability to concentrate the magnetic flux of magnetically transmitted signals, but it has a sensitive effect on the interrogator circuit. It will be understood by those familiar with this technique that by adjusting these resonance voltages -5-(Please read the precautions on the back before filling this page)
