Abstract:
1. A tag comprising an integrated circuit thereon, including memory, antenna means for RF transmission of data acquired by the integrated circuit, a sensor sensing environmental conditions to which said sensor is subjected, said sensor providing signals based on the environmental conditions to the integrated circuit, a thermistor device for increasing the accuracy of the tag wherein said thermistor generates resistance signals and said tag performs on-board calculations only in resistance units and does not convert the resistance values to temperature values thereby confining on-board calculation data to a resistance domain and leaving conversion of the data to a temperature domain for an external device once the data is retrieved from the tag's memory, wherein said thermistor device is connected to an elongated conductor only on one side which in turn connects to an I/P terminal of said tag in a manner to render said tag for generating resistance values including more than one of vibration, pressure, radiation, shock, light, position and atmospheric pressure; a device for stopping manually said tag's environmental data acquisition at a predetermined point, wherein said sensor is contained in a rigid stylus wherein said tag and said sensor are encased in food or pharmaceutical grade heat shrink flexible plastic in a way that when heated under pressure said tag and said sensor form a single waterproof unit.
