Food safety indicator
First Claim
1. A food safety device for placement on a product comprising:
- a light sensor configured to detect light to which the product is exposed;
one or more visual indicators configured to display a visual indication of freshness and/or safety of the product;
an antenna configured to transmit and receive data regarding the detected light to which the product is exposed and the freshness and/or safety of the product; and
a logic module configured to execute programmable logic to determine the freshness and/or safety of the product from the detected light to which the product is exposed, to cause the one or more visual indicators to display a visual indication of the freshness and/or safety it determines, and to transmit and receive data regarding the detected light to which the product is exposed and the freshness and/or safety of the product via the antenna,wherein said light sensor comprises a photovoltaic solar cell that is configured to detect the light to which the product is exposed and to power the one or more sensors, the one or more visual indicators, the antenna, and the logic module.

Abstract
A food safety device for placement on a product is disclosed. The food safety device comprises one or more sensors that measure at least one condition of the product and/or its environment, one or more visual indicators that are configured to display a visual indication of freshness and/or safety of the product. An antenna transmits and receives data regarding the at least one measured condition of the product and the freshness and/or safety of the product. A logic module executes programmable logic to determine the freshness and/or safety of the product from the at least one measured condition of the product, to cause the one or more visual indicators to display a visual indication of the freshness and/or safety it determines, and to transmit and receive data regarding the at least one measured condition of the product and the freshness and/or safety of the product via the antenna.
