20130161386 | ELECTRONIC MONITORING SYSTEMS, SHIPMENT CONTAINER MONITORING SYSTEMS AND METHODS OF MONITORING A SHIPMENT IN A CONTAINER - A shipping container has 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 inputting PF 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. | 06-27-2013 |
20130278391 | METHOD AND SYSTEMS OF TAGGING OBJECTS AND READING TAGS COUPLED TO OBJECTS - 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.
