Abstract

A tag for sensing environment conditions in a package may be located within the package or external thereto, and is encased within a food or pharmaceutical grade material such that the tag is hermetically sealed within the material and will not be affected by the environmental conditions to which it will be subjected. The sensor affiliated with the tag can also be located at an end of a conductor or probe that also is hermetically sealed to the material encasing the tag itself. The sensor, remotely located with respect to the tag, may be located within the package being monitored, while the tag itself is located external to the package. The probe may be formed of stainless steel with the sensor being mounted within the tip of the probe to facilitate penetration of the probe into the package.

Claims

1. A tag comprising an integrated circuit thereon, including antenna means for RF transmission of data acquired by the integrated circuit, a sensor sensing environmental conditions to which the sensor is subjected, said sensor providing signals based on the environmental conditions to the integrated circuit, and means hermetically sealing said tag within an enclosure composed of food or pharmaceutical grade material.

2. The tag of claim 1 wherein said sensor is connected to one end of a conductor permitting the sensor to be placed at a distance from the integrated circuit of the tag, said conductor also being hermetically sealed within food or pharmaceutical grade material.

3. The tag of claim 1 wherein said food or pharmaceutical grade material is a heat shrink flexible plastic material.

4. The tag of claim 1 wherein the sensor is contained in a tip of a rigid stainless steel stylus or probe, the proximal end of which is encased in food or pharmaceutical grade heat shrink plastic tubing extending proximally to the integrated circuit of the tag such that when heat and pressure are applied the tubing is sealed into the material hermetically sealing the tag to form a single waterproof unit.

5. The tag of claim 1 wherein the sensor is contained in a tip of a rigid stainless steel stylus or probe and the sensor is embedded in a container or vessel, the contents of which require monitoring.

6. The tag of claim 5 wherein the tag is located on the exterior of the container or vessel.

7. The tag of claim 5 wherein the tag is located at a distance from the container or vessel and is connected to the probe.
