摘要:
An area-reading antenna (in RF linkage with myriad RF tags) is dynamically tuned. It may be dynamically tuned as to its transmission of a power/clock field, or dynamically tuned as to its transmission of a data signal, or dynamically tuned as to its reception of a data signal, or some combination of all three. In this way, a base station has an improved ability to communicate with a greater fraction of the RF tags within its reading area, despite detuning of individual tags due to proximity of detuning influences such as metal or liquids.

The invention disclosed provides a method, system, and associated tag for detection and tracking of inanimate and animate objects. The novel method broadly comprises the steps of: a) attaching a low radio frequency detection tag to each of the objects, each tag comprising a tag antenna operable at a low radio frequency not exceeding 1 megahertz (preferably not exceeding 300 kilohertz), a transceiver operatively connected to the tag's antenna, the transceiver being operable to transmit and receive data signals at the low radio frequency, a data storage device operable to store data comprising identification data for identifying said detection tag, a programmed data processor operable to process data received from the transceiver and the data storage device and to send data to cause the transceiver to emit an identification signal based upon the identification data stored in said data storage device, and an energy source for activating the tag's transceiver and data processor; b) storing, in the data storage device of each tag, shipping data selected from object description data, address-of-origin data, destination address data, object vulnerability data, and object status data; c) commingling the objects in a repository selected from a warehouse and a truck, the repository being provided with at least one large loop field antenna operable at said low radio frequency; the field antenna being disposed at a distance from each object that permits effective communication therewith at the low radio frequency, d) reading the identification data and shipping data from the transceiver of each tag by interrogating all tags commingled in said repository with data signals, such as specific IP addresses or other identification codes, via said field antenna; and e) transmitting the identification data and shipping data from each tag to a central data processor to provide a tally of the objects in said repository.

摘要:
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 said event signals to a data storage apparatus, said data storage apparatus being operable to store said temporally ordered series of said event signals; and d) safeguarding the aforesaid data storage apparatus against alteration of said stored series of event signals. The safeguarding may be done by selecting a data storage apparatus which is unalterable, such as a write-once-only CD-R disc. Such use of an unalterable medium (e.g. CD-R) is especially appropriate where the repository is movable, such as a truck or railway car, since a CD-R drive can easily be located within the movable repository during shipment of the goods which are sensitive to temperature or other environmental events. Alternatively, safeguarding can be achieved by locating the aforesaid data storage apparatus at a secure location (e.g. KPMG or other auditor's offices) distant from the stored/shipped drugs to prevent data tampering. Moreover, the event data can be transmitted (wirelessly for movable repositories, by wired connection for a stationary repository such as a warehouse) to the distant location immediately, as the events occur (i.e. in “real time”), so that the event data is in secure hands (e.g. an independent auditor's) before it could possibly be altered. Furthermore, safeguarding may utilize a selected algorithm to calculate a pair of checksums based on a selected sequence of event signals, said pair of checksums having a selected relationship (e.g. being identical) in the event of data integrity, one of the two checksums being calculated from event signals generated at the repository (e.g. at a warehouse), the other checksum being calculated from event signals that have already been transmitted to the aforesaid data storage apparatus. Moreover, corresponding temporal (e.g. date/time) data may be stored together with each event signal, the temporal data being obtained from an independent source (e.g. National Institute of Standards and Technology (NIST) or a GPS satellite).

In a system for displaying prices in a retail store, improved rail arrangements permit improved accuracy in confirming the physical location of an improved display device on one such rail arrangement. A response from the device to a host, or central computer, indicates a particular position of the device on the rail arrangement.
