Document Type and Number:
Japanese Patent JP2002512739
Kind Code:
A
Abstract:
A method for accounting for individual ones of a plurality of items based upon random times that occur as a function of a first specified time interval, and a random interval inventory system that operates in accordance with the method. The method includes a first step of transmitting information signals based upon random times from individual ones of a plurality of tags (5a1-5xx) to at least one of at least one master transceiver and at least one transceiver (4a-4n). The individual tags (5a1-5xx) are affixed to respective individual ones of a plurality of items. The information signals transmitted from each tag (5a1-5xx) correspond at least to the respective item to which the tag (5a1-5xx) is affixed. The random times occur as a function of a first specified time interval. For a case wherein the information signals are transmitted to the at least one remote transceiver, each at least one remote transceiver (4a-4n) receives information signals from at least one of the tags (4a-4n), and in response to receiving each information signal, relays the signal to the master transceiver (3). In response to the master transceiver (3) receiving an information signal, a next step includes supplying the signal to an associated confirmation device (2). Within the confirmation device (2), in response to receiving an information signal from the master transceiver (3), a next step includes confirming that the item corresponding to the information signal is accounted for.
