Method for tracing a product through successive stages of production and conservation, comprises use of integrated circuit and memory which stores physical parameter, history and standards

摘要

The traceability equipment consists of an integrated circuit (2) with microprocessor (5) and memory (6), a temperature sensor (4), an antenna (7) and battery (3). The memory stores a script which details the locations the product will visit and associated permissable temperatures. Any deviation from passage through a scripted series of locations or from the associated temperatures is signalled to the current location or a central computer An INDEPENDANT CLAIM is also included for : A traceability equipment which has a sensor to measure a physical quantity such as temperature and means to signal by radio deviations of the quantity from a reference value
