摘要： A system uses a large loop antenna, connected with a transceiver operating below 1 MHz. The loop antenna is deployed from a spool to surround a crime scene, and may carry indicia communicating that it is a crime scene boundary. The system interrogates devices, including evidence bags and badged personnel, as they enter and leave the scene. The system can optionally log the time of salient events. A second loop antenna can log evidence bags as they enter a vehicle. The devices can be silenced by the transceiver and thus collisions can be reduced and avoided among responses from devices. The system performs “area reads” that would not be possible if higher RF frequencies were employed.

摘要： A cementitious container that has a low-frequency radio tag containing the container's pedigree and history. The container is used for storage of hazardous waste are disclosed having an inner layer of substantially unhydrated cement in contact with the hazardous waste and an outer layer of hydrated cement. Cementitious hazardous waste containers may be prepared by compressing powdered hydraulic cement around solid hazardous waste materials as well as the encapsulated radio tag that uses low frequency communication. This makes it possible to read and write information though the wall of the container as during transportation to a storage site. Once placed at the storage site, the pedigree, (history contents, Chain of Possession, Proof of delivery, weight), may be checked and verified by reading the tag on a regular basis, (once an hour), to confirm the vessel is intact and has not been moved. Sensors may also be placed on the radio tag to monitor critical parameters like temperature, light levels, movement detectors, and radioactive levels. These may be reported back via the data-link on a regular basis and may also be used as alarms if one moves outside of a specified range.

摘要： A low frequency inductive two-way radio transceiver tag is provided that has separate antennas for transmitting and receiving signals within a reading volume. Thus, the tag of the invention includes both a transmit antenna and a receiving antenna, either separately or as a single antenna tuneable between two functional states with different impedances. The impedance of the receiving antenna is greater than the impedance of the transmitting antenna. For example, the impedance of the receiving antenna may be greater than the impedance of the transmitting antenna by a factor of 103.

摘要： A method, system and RF tag for tracking and locating travel bags during their shipment (e.g. by airlines) by providing owner's identification, destination, historical, and other pedigree information about such shipped travel bags. The RF travel tags are active (e.g. battery or solar cell powered), operate at low radio frequencies, below 15 MHz (e.g. 128 kHz), and comprise a large storage device which stores information. The stored information comprises both identification information that identifies said travel bag and an owner (e.g. name, address) thereof and database information concerning characteristics of the travel bag, the database information including the destination, origin, travel history of the bag, and historical characteristics of said travel bag. The RF travel bag tag has a first loop antenna, a transceiver operatively connected with the first antenna and operable to receive a first RF interrogation signal at a low frequency not exceeding 15 MHz (e.g. 128 kHz) from a first reader and to transmit RF signals in response.
