Method for monitoring objects with transponders
First Claim
1. A method for tracking environmental exposure of an object comprisingselecting said object ;
- associating a radiofrequency identifier with the object, the radiofrequency identifier comprisingan antenna for transmitting or receiving radiofrequency energy; and
an integrated circuit chip connecting with said antenna, said chip having a memory;
exposing the object to an environmental condition;
measuring said environmental condition as an environmental parameter with a sensor physically separate from said radiofrequency identifier;
transmitting the environmental parameter from said sensor to a reader/writer, and writing said enviromnental parameter from the reader/writer to the memory of the chip by transmitting radiofrequency energy to the radiofrequency identifier.

59. A system for tracking environmental exposure of an object comprising
a. a radiofrequency identifier comprisingan antenna for transmitting and receiving radiofrequency energy; - and
2) an integrated circuit chip connecting with said antenna, said chip having a memory; b. a physically separate sensor capable of measuring an environmental condition as an environmental parameter; c. a reader/writer for reading data from the radiofrequency identifier by transmitting radiofrequency energy thereto and receiving radiofrequency energy therefrom, wherein the sensor transmits the environmental parameter to said reader/writer which writes the ammeter to the memo of the chip; d. an electronic data management system comprising; 1). a data memory for storage of data; 2). a microprocessor for performing operations on said data; and 3). a signal output for outputting a signal relating to the data or the outcome of an operation on the data; and e. a network computer system, able to access data from said electronic data management system, comprising 1). a data memory for storage of data; 2). a microprocessor for performing operations on said data; and 3). a signal output for outputting a signal relating to the data or the outcome of an operation on the data;
whereby said system operates by a method for tracking environmental exposure of an object comprising;f. selecting the object; g. associating said radiofrequency identifier with said object, h. exposing the object to an environmental condition; i. measuring the environmental condition as an environmental parameter with said physically separate sensor; j. writing said environmental parameter to said data memory of the chip of said radiofrequency identifier by transmitting radiofrequency energy thereto; and k. either, transferring said environmental parameter data from the memory of said radiofrequency identifier-, or transmitting said environmental parameter data from the reader/writer, to said electronic data management system.
