Appl. No.:

09/940142

Inventors:

Larry Runyon - Richland WA
Wayne M. Gunter - Richland WA
Ronald W. Gilbert - Richland WA

Assignee:

Battelle Memorial Institute - Richland WA

International Classification:

G08B 1300

US Classification:

340541, 340540, 3405451, 340531, 340539

Abstract:

A security system for a building facility where radio frequency tamper-indicating devices are placed in the area of the facility to detect movement and/or relative movement of components under circumstances where such movement may indicate a security risk. One example is where there are ceiling tiles in a false ceiling which may be moved during a covert entry. An RF damage indicating device is placed at juncture locations of the tiles and tendrils of the tamper-indicating devices are positioned so that movement of one of the tiles will break the tendril and cause an alarm signal to be given. In other arrangements, tamper-indicating devices could be attached to security-sensitive objects, containers for the same, and building-related components so that movement of these security-sensitive objects would also trigger an alarm.

Abstract:

A multi-frequency RFID remote communication system is provided that includes a plurality of RFID tags configured to receive a first signal and to return a second signal, the second signal having a first frequency component and a second frequency component, the second frequency component including data unique to each remote RFID tag. The system further includes a reader configured to transmit an interrogation signal and to receive remote signals from the tags. A first signal processor, preferably a mixer, removes an intermediate frequency component from the received signal, and a second processor, preferably a second mixer, analyzes the IF frequency component to output data that is unique to each remote tag.

International Classification:

H04Q 522

US Classification:

340 104

Abstract:

A radio frequency identification system having a radio frequency transceiver for generating a continuous wave RF interrogation signal that impinges upon an RF identification tag. An oscillation circuit in the RF identification tag modulates the interrogation signal with a subcarrier of a predetermined frequency and modulates the frequency-modulated signal back to the transmitting interrogator. The interrogator recovers and analyzes the subcarrier signal and determines its frequency. The interrogator generates an output indicative of the frequency of the subcarrier frequency, thereby identifying the responding RFID tag as one of a âclassâ of RFID tags configured to respond with a subcarrier signal of a predetermined frequency.

Abstract:

A system for reducing security risks in, for example, an enclosed area where there are documents, computer discs, and other items which may contain security sensitive information. Each security sensitive item has an RFID tag attached thereto, and during non-working hours these items are placed in locked file cabinets, a safe or a vault. The area is periodically interrogated by an RF interrogator to ascertain whether the items are in their locked secured position or are in an open area.

International Classification:

G05B 19/00

US Classification:

340 561, 3405723

Abstract:

A system and method for controlling remote devices utilizing a radio frequency identification (RFID) tag device having a control circuit adapted to render the tag device, and associated objects, permanently inoperable in response to radio-frequency control signals. The control circuit is configured to receive the control signals that can include an enable signal, and in response thereto enable an associated object, such as a weapon; and in response to a disable signal, to disable the tag itself, or, if desired, to disable the associated weapon or both the device and the weapon. Permanent disabling of the tag can be accomplished by several methods, including, but not limited to, fusing a fusable link, breaking an electrically conductive path, permanently altering the modulation or backscattering characteristics of the antenna circuit, and permanently erasing an associated memory. In this manner, tags in the possession of unauthorized employees can be remotely disabled, and weapons lost on a battlefield can be easily tracked and enabled or disabled automatically or at will.

Other systems and methods for remotely monitoring the status of multiple fire extinguishers are also provided.

International Classification:

US Classification:

340 101, 340 104, 340 105

Abstract:

A radio frequency (RF) communication system employs phase-modulated backscatter signals for RF communication from an RF tag to an interrogator. The interrogator transmits a continuous wave interrogation signal to the RF tag, which based on an information code stored in a memory, phase-modulates the interrogation signal to produce a backscatter response signal that is transmitted back to the interrogator. A phase modulator structure in the RF tag may include a switch coupled between an antenna and a quarter-wavelength stub; and a driver coupled between the memory and a control terminal of the switch. The driver is structured to produce a modulating signal corresponding to the information code, the modulating signal alternately opening and closing the switch to respectively decrease and increase the transmission path taken by the interrogation signal and thereby modulate the phase of the response signal. Alternatively, the phase modulator may include a diode coupled between the antenna and driver. The modulating signal from the driver modulates the capacitance of the diode, which modulates the phase of the response signal reflected by the diode and antenna.
