RADIO FREQUENCY IDENTIFICATION TAGS FOR USE IN EXTREME ENVIRONMENTS
First Claim
1. A portable RFID (Radio Frequency Identification) tag, comprising:
- one or more sensors, each sensor measuring a condition of an environment within which the RFID tag is disposed;
circuitry obtaining data from measurements provided by each sensor;
a transceiver modulating a radio frequency (RF) signal carrying the obtained data; and
an antenna, electrically coupled to the transceiver, transmitting the RF signal,wherein the circuitry, transceiver, and antenna are potted in their entirety in a thermosetting plastic epoxy.

Abstract
A portable RFID (Radio Frequency Identification) tag includes one or more sensors. Each sensor measures a condition of an environment within which the RFID tag is disposed. Circuitry obtains data from measurements provided by each sensor. A transceiver modulates a radio frequency (RF) signal carrying the obtained data. An antenna, electrically coupled to the transceiver, transmits the RF signal. The circuitry, transceiver, and antenna are potted in their entirety in a thermosetting plastic epoxy for purposes of enduring extreme environmental conditions. The one or more sensors can include a temperature probe. A portion of this temperature probe can serve as the antenna.
