Abstract: This invention relates to a method and system for auditably authenticating the histories of events (e.g. temperature levels) experienced by objects (e.g. pharmaceutical products, foodstuffs, etc.) during storage in repositories such as warehouses and movable shipping vehicles. The method involves a) sensing an event experienced by an object; b) recording an event signal that defines the sensed event; c) transmitting a temporally ordered series of the event signals to a data storage apparatus, the data storage apparatus being operable to store the temporally ordered series of the event signals; and d) safeguarding the aforesaid data storage apparatus against alteration of the stored series of event signals.

Abstract: A method for providing real-time visibility on a construction project includes steps of: attaching a low-frequency, ultra low-power, two-way transceiver radio tag to each construction material to be used in the construction project; storing data relating to the construction material in the tag; and reading the data from the transceiver of the tag by interrogating the radio tag with radio frequency interrogation signals.

The components are: a radio frequency modem operable at a low radio frequency, a loop antenna, a programmable microprocessor, a memory, and a connector for a battery.

Abstract: The invention provides a method for controlling the operating state of a lock characterized by a locked state and an unlocked state. The method comprises: entering secret information on an electronic input device (e.g. keypad) located on a radio frequency identity card, then electronically comparing the secret information against an authorized code to determine whether the secret information is authorized, then transmitting by radio frequency an unlocking signal to a radio frequency reader located at the lock for opening the lock in the event that the secret information is authorized. In a related use of such RF identity cards, the invention also provides a system and method of tracking movements of individuals within a secure area.

Abstract: 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.

Abstract: 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.
