METHOD AND SYSTEM FOR DETERMINING THE CONDITION OF A TIME-TEMPERATURE INDICATOR
First Claim
1. A device for use in controlling the quality of a perishable object, while progressing on its supply line, by monitoring the condition of a time-temperature indicator (TTI) associated with the object, the device comprising a sensing assembly for detecting a response of the TTI to a predetermined stimulus and generating measured data representative thereof, said measured data being indicative of the condition of the TTI, thereby enabling the determination of the remaining shelf life of the TTI and thereby any perishable good to which it is attached and calibrated.

2. (canceled)
- 16. A label, tag or packaging material, comprising a machine readable pattern having at least one feature of the pattern configured as a time-temperature indicator (TTI), said pattern being responsive to a predetermined stimulus in a time-temperature variable manner in accordance with time-temperature variations of the TTI.
- 18. An object carrying a machine readable pattern that includes at least one feature of the pattern configured as a time-temperature indicator (TTI), said pattern being responsive to a predetermined stimulus in a time-temperature variable manner in accordance with time-temperature variations of the TTI.

20. A method for use in controlling an object while progressing on a supply chain, the object being associated with a time-temperature indicator (TTI), the method comprising:
-
at a node of the supply chain, detecting a response of the TTI to a predetermined stimulus and generating measured data representative thereof, processing said measured data to determine the condition of the TTI, thereby enabling determination of remaining shelf life of said TTI thus enabling to define the object progress to a further node of the supply chain. - View Dependent Claims (21)
