International Classification:

G08B013/14

US Classification:

3405721, 3405724, 3405681, 340505

Abstract:

A system is disclosed for detecting the presence of an article. The system includes a transmitter for radiating a first electromagnetic signal at a predetermined primary frequency and a resonant tag secured to the article. The resonant tag generates a second electromagnetic signal in response to receiving the first electromagnetic signal. The second electromagnetic signal has components at the primary frequency and at a predetermined secondary frequency different from the primary frequency. The system also includes a receiver for receiving the second electromagnetic signal and a computer connected to an output of the receiver. The computer processes the received second electromagnetic signal and generates an output signal when the secondary frequency is detected in the second electromagnetic signal.

Abstract:

A method of making a resonant frequency tag which resonates at a predetermined frequency. The method involves providing a first conductive pattern having an inductive element and a first land and a second conductive pattern having a second land and a third land which are joined together by a link. The second conductive pattern is overlaid the first conductive pattern such that the second land is positioned over the first land. The third land is in electrical communication with the inductive element of the first conductive pattern. The formed resonant frequency tag is energized to determine if the tag resonates at the predetermined frequency. If the tag resonates properly, the third land is electrically coupled to the inductive element. If it does not, the second conductive pattern is adjusted so that overlapping portions of the first and second lands are changed, altering the capacitance to adjust the resonant tag frequency.

Abstract:

A method of making a resonant frequency tag having a predetermined frequency comprises forming a first conductive pattern comprising an inductive element and a first land having a first end connected to an inductive element end, and a second end spaced a predetermined distance from the first end; separately forming a second conductive pattern comprising a second land having a predetermined width and a link element; placing the second conductive pattern proximate the first conductive pattern at a first location wherein the second land overlies a portion of the first land with a dielectric therebetween establishing capacitive element plates having a first capacitance along with the inductive element forming a resonant circuit; measuring the resonant circuit frequency and comparing the measured and predetermined frequencies moving the second land along of the first land length to match the resonant frequency; and securing the second conductive pattern to the first conductive pattern.

Abstract:

A tracking system uses RFID (radio frequency identification) tag technology to facilitate the identification and tracking of items in an environment through a technique known as shadowing. As an object or target moves within a pre-described detection zone with communicating antenna and RFID sensors, the object or target blocks the line of sight between respective antenna and sensors, preventing electromagnetic coupling between the sensor and the antenna and thus casting an electromagnetic shadow along the line of sight. One approach of this invention uses this shadow technique to perform functions such as theft (shrink) deterrence/detection; tracking the motion of objects through an environment by monitoring the shadow; and correlation analysis of people shadows to tagged items (e. g. , merchandise, articles) to foster marketing and merchandizing effectiveness.

International Classification:

G08B 13/14

US Classification:

340571, 29846

Abstract:

A circuit element the presence of the circuit element includes first and second capacitor plates disposed over the surface of the substrate in an aligned relationship with each other. The aligned relationship has manufacturing variations in the relative positioning of the first and second capacitor plates and a dielectric layer disposed between the first and second capacitor plates. At least one of the first and second capacitor plates is formed substantially smaller relative to the other of the first and second capacitor plates. The at least one of the capacitor plates is disposed at a predetermined offset in at least one planar direction from an edge of the other of the first and second capacitor plates. The predetermined offset is selected according to the manufacturing variations to prevent variations in the value of capacitance of the capacitor due to the manufacturing variations.
