20080218348 | Visibility radio cap and network - A pedigree tag for tracking and validating authenticity of contents in a container includes: a radio frequency modem operable at a low radio frequency, not exceeding one megahertz, and including a full duplex transmitter and receiver; an antenna operatively coupled with the radio frequency modem; a programmable microprocessor operatively coupled with the radio frequency modem; a memory operatively coupled with the programmable microprocessor; a clock; and a connector for connecting a power source for providing power to the microprocessor; wherein the pedigree tag is in a form factor conformable to the container to which it is affixed. | 09-11-2008 |
20080238672 | EVIDENCE TRACKING - 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. | 10-02-2008 |
20080275287 | RF-ENABLEMENT OF AUDITABLE STORAGE FOR HAZARDOUS MATERIALS - 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. | 11-06-2008 |

20100295682 | Radio tag and system - Passive tags use two antennas with only limited mutual coupling, one of which receives a power/clock field and the other of which receives a data signal. An area-reading antenna, or two or more antennas, are deployed to generate the power/clock field, from a base station. The base station, or active tags, or both, generate the data signals from time to time. This topology together with the use of low frequencies permits area reads, and permits small and economical passive tags, and further permits localization of a particular passive tag as being nearby to a particular active tag. | 11-25-2010 |
