Abstract:

A tire monitoring system providing tire status and notifying or warning the vehicle operator of early detection of imminent tire failure and performance degradation; thus improving safety by preventing blowouts from occurring, lengthening tire life by encouraging preventive maintenance, and improving fuel mileage by encouraging the operator to fill the tire to its proper pressure or repair it. The system monitors temperature of the rim of the wheel to which the tire is attached, such temperature being transmitted to the vehicle operator or other interested parties via means such as radio frequency.

Keystone Technology Solutions, LLC - Boise ID

International Classification:

H01Q 1/42

US Classification:

343872, 343893

Abstract:

A shipping container has a passive radio antenna element having internal and external antennas. A connector spanning the wall joins the two antennas. An internal communications device is disposed within the container and an external communications device is disposed external to the container. Another shipping container has a repeater element having internal and external antennas. A repeater unit spans the wall joining the two antennas. A communications device is disposed within the container and another communications device is disposed externally. RF signals are re-radiated by the antennas. Methodology includes emitting RF signals from a communication device disposed at a first location, receiving the signals through an antenna comprised by an antenna element, and re-radiating the signal from a second antenna comprised by the element, where the element spans the wall of a shipping container. The re-radiated signal is received by a second communications device disposed at a second location.

Abstract:

Methods and systems of attaching a radio transceiver to an antenna. At least some of the illustrative embodiments are systems comprising an antenna and an integrated circuit configured to operate as a radio transceiver. The antenna comprises a ground plane having a first edge surface, and an active element having a second edge surface. The ground plane and the active element are retained together such that the first and second edge surfaces are substantially coplanar and form an antenna edge. The integrated circuit is configured to operate as a radio transceiver, and the integrated circuit is mechanically coupled to the edge of the antenna and electrically coupled to the active element.

International Classification:

G08B 13/14

US Classification:

3405728, 3405727

Abstract:

Methods and systems of tagging objects and reading tags coupled to objects. At least some of the illustrative embodiments are systems comprising a reading antenna, a tag reader coupled to the reading antenna, and a radio frequency identification (RFID) tag comprising a tag antenna electromagnetically coupled to the reading antenna. The RFID tag couples to an object such as the body of a living organism or a metallic article. Moreover, the tag antenna has a far-field radiation pattern in a direction away from the object that is substantially unaffected by proximity of the RFID tag to the object, and substantially unaffected by which surface of the RFID tag faces the object.

US Classification:

3405727, 3405721, 343860

Abstract:

Methods and systems of RFID tags using RFID circuits and antennas having unmatched frequency ranges. At least some of the illustrative embodiments are RFID tags comprising a RFID circuit configured to operate with an antenna having a first range of resonant frequencies, a tag antenna coupled to the RFID circuit (the tag antenna having a range of resonant frequencies different than the first range of resonant frequencies, the range of resonant frequencies of the tag antenna being a second range of resonant frequencies).

Abstract:

Methods and systems of changing antenna polarization. At least some of the illustrative embodiments are systems comprising an antenna having a first feed point and a second feed point, an antenna communication circuit, and a switch assembly that selectively couples the antenna communication circuit to the first feed point, and that selectively couples the antenna communication circuit to the second feed point. The feed point (or group of feed points) is selected, for example, based on polarization of an electromagnetic wave to be radiated from or received by the antenna.
