Abstract:
The invention relates to an event driven content switching technology in a passive, batteryless radio frequency identification (RFID) tag. The RFID tag device monitors the occurence of an external event such as a change in the environment. The switching of the context of the tag is effected by sensors incorporated in the tag. An external event triggers the switch. An RFID reader may subsequently read out the occurrence of the event due to the switch change. Different alignments of the switch could bring about the closing or opening of specific electronic circuits within the RFID tag that effect the storing of information in a selected memory, or changing the ID transmitted by the tag. In a particular embodiment this latter is accomplished by shorting one or the other of two RFID tag antennas. When one antenna is shorted, the second tag's ID is sent, and vice versa.
Abstract:
Disclosed are systems and methods for preventing unauthorized persons from using an electronic device within a facility. In such an embodiment, the system may include a RFID tag having unique identification information associated with a wearer of the RFID tag. The RFID tag may be comprised in a non-removable item worn by the wearer, such as a bracelet. This system may also include an RFID reader associated with the electronic device and having an RFID coverage zone for detecting RFID tags within the coverage zone. A device management system may be connected to the reader and configured to determine whether a wearer in the coverage zone is authorized to use the electronic device based at least in part on detected RFID tag's unique identification information. In such an embodiment, the device management system is configured to activate the electronic device if it determines the authorized wearer is detected in the coverage zone.
Abstract:
A radio frequency identification seal comprises an antenna including a main antenna portion and at least one break-away portion and an RFID tag coupled and tuned to the antenna. The RFID tag outputs a signature in response to a scanning signal when tuned to the antenna.
Abstract:
A MOS RF surveillance and/or identification tag, and methods for its manufacture and use. The tag includes an interposer, an antenna/inductor, and integrated circuitry on the interposer. The integrated circuitry has a lowest layer in physical contact with the interposer. The method of manufacture includes forming a lowest layer of integrated circuitry on an interposer, forming successive layers of the integrated circuitry on the lowest layer of integrated circuitry, and attaching an electrically conductive functional layer to the interposer. Alternatively, an electrically conductive structure may be formed from a functional layer attached to the interposer. The method of use includes causing/inducing a current in the present tag sufficient for it to generate, reflect or modulate a detectable electromagnetic signal, detecting the signal, and optionally, processing information conveyed by the detectable electromagnetic signal.
Abstract:
An electronic article surveillance system is disclosed. The system of the present invention has a moisture-sensitive article placed within a canister having a non-static desiccant material and an activated electronic article surveillance radio frequency (EAS RF) device. The EAS RF device is placed between a Generally Regarded as Safe qualified label and a release liner which is applied to the canister. The system also has an EAS RF detector which monitors an associated interrogation zone for a signal from the activated EAS RF device thereby activating an alarm.

Abstract:
An entry detecting system includes a terminal device; a point-to-point communication device; an entry detecting device; and a guard device. The point-to-point communication device includes a transmitting-receiving antenna having directivity in a specific direction. The point-to-point communication device communicates by radio with the terminal device via the transmitting receiving antenna so as to detect a response time from the terminal device and report detected response time to the entry detecting device. The entry detecting device detects a distance from the point-to-point communication device to the terminal device based on the response time reported by the point-to-point communication device, generates entry detecting information based on the detected distance, and transmits the entry detecting information to the point-to-point communication device and the guard device. The point-to-point communication device transmits the received entry detecting information to the terminal device.
Abstract:
Embodiments include methods and apparatus for detecting proximity of an electronic article surveillance (EAS) tag. A proximity detection system (e.g., a radio frequency identification (RFID) tag reader) detects a presence of an object within a first area. In response to detecting the proximity of the object, an EAS tag reader alters characteristics of an EAS tag detection signal that is produced by the EAS tag reader in order to detect an EAS tag within range of the EAS tag reader.
Abstract:
A blister package with an integrated RFID tag is provided. The conductive lidding material is modified to serve not only to seal some contents within some formed blister film, but also to act as an RFID tag antenna. An IC chip is electrically connected to the lidding film antenna. Methods of manufacture which integrate with conventional blister package manufacturing processes are also provided.
