    摘要： The invention relates to a special type of magnetic tag that serves both as an identifier of the article to which it is attached and as an antitheft device. Identification comes about through the use of an array of individual magnetic elements that are closely spaced, preferably along and perpendicular to an amorphous wire or strip. The wire or strip forms an integral part of the identification array and can be used as an anti-theft device to trigger an alarm when activated by an external field from a magnetic gate. The array may be personalized (coded) by leaving out elements of the array or by driving selected elements to saturation while others remain demagnetized. The elements can also be in the form of a double array to constitute `l`s and `0`s to form a code. Reading of the elements (code) is accomplished with a special reading head consisting of one or more small magnetic circuits coupled to one or more pickup loops utilizing, in some cases, the Matteucci effect.

    摘要： A transponder is disclosed comprising a resonant RLC circuit with one or more components that can be connected or disconnected non-destructively using switches that respond to an externally applied magnetic field. The switching in or out of the components causes a change in the resonant frequency of the original RLC circuit that is detected by the base station sweeping a carrier signal through a range of frequencies to detect a returned signal that changes when the carrier signal frequency matches the resonant frequency of the resonant circuit/tag. The resonant frequency changes when one or more of the circuit components is connected or disconnected. Each switch transfers at a unique magnetic field intensity so that electrical contact is achieved at a predetermined value of an externally applied magnetic field. The detected changes are used to create a code that is used to pass information from the resonant circuit/tag to the base station.

    摘要： The invention relates to a special type of magnetic tag that serves both as an identifier of the article to which it is attached and as an antitheft device. The former attribute is especially important should stolen property be recovered. Identification comes about through the use of an array of individual magnetic elements that are closely spaced, preferably along and perpendicular to an amorphous wire or strip. The magnetic elements can take the form of magnetic ink, high coercivity wire, thin foil, or amorphous wire. The array may be personalized (coded) by leaving out elements of the array or driving selected elements to saturation while others remain demagnetized. The elements can also be in the form of a double array to constitute `1`s and `0`s to form a code. Reading of the elements is accomplished with a special reading head consisting or one or more small magnetic circuits coupled to one or more pickup loops. A longer length of soft magnetic wire or thin strip is used to trigger an anti-theft alarm when activated by an external field from a magnetic gate.

    摘要： A transponder has a resonant RLC circuit with one or more electromagnetic energy storage components that vary in response to an externally applied modulating energy field. In addition to the externally modulating energy field, a base station transmits a carrier signal with a frequency essentially the same as the quiescent resonant frequency of the RLC circuit. As the component(s) vary, the resonant frequency of the RLC circuit changes, modulating the carrier signal with the external modulating energy field. Effects of the modulation are detected by the base station. Information (e.g., the presence of a tag) is obtained by receiving and demodulating the modulated signal at the base station. One or more of the circuit elements (e.g., different preferred embodiments of one or more capacitors, inductors, and resistors) can be varied (e.g. mechanically) to modulate the carrier signal. This allows the resonant circuit to modulate the carrier signal with multiple modulation frequencies to encode multiple bits of information on the carrier.
