Apparatus and method for monitoring and communicating data associated with a product
First Claim
1. A condition monitoring system, comprising:
- a radio frequency transponder module including a RFID chip having a first memory and an antenna;
at least one sensor module that monitors data related to the condition of a product, and includes a second memory for storing the monitored data; and
a communication interface that couples the at least one sensor module to the RFID chip;
wherein the sensor module communicates with the RFID chip by way of the interface and updates the first memory with data related to the product.

Abstract
Visual and audio communication interface for a perishable integrity indicator system which includes a RFID transponder and perishable integrity sensor. A perishable integrity indicator system includes a RFID transponder and a perishable integrity sensor. The RFID transponder includes a RF integrated circuit coupled with an antenna. The sensor monitors the time and temperature of the perishable. A freshness determining module receives time- and temperature-dependent measurement data from the perishable integrity sensor and determines a current freshness status. A communications interface to the RFID transponder permits a RFID reader to retrieve current freshness status data corresponding to the freshness status determined by the freshness determining module. The system further includes a power management module. The visual and audio communication interface provides a communications means for sending sensor alerts, sensor setup and history as either a supplement to the RF communication or as an alternative to RF when RF is either not available or not able to communicate.
