Device and method for identifying a container
First Claim
1. A device associated with a container containing contents, the device comprising:
- a valve assembly configured to control passage of the contents of the container, wherein the valve assembly is positioned to be in contact with the contents inside the container;
a wireless communication device positioned with the valve assembly and configured to wirelessly communicate information associated with the container; and
a discharge capacitor associated with the wireless communication device;
wherein the wireless communication device is further configured to determine the temperature of the contents inside the container based on the discharge rate of the discharge capacitor.

Abstract
The present invention relates to a wireless communication device and a method for identifying a container for containing contents such as solid, liquid, or gaseous materials. The device includes a wireless communication device for transmitting information regarding the container. A valve assembly is positioned over an opening in the container for controlling the flow of contents from the container. The wireless communication device is mounted within the valve assembly, and preferably within the ball. The wireless communication device communicates information to an interrogation reader. The temperature associated with the container and/or its contents may be determined by various techniques including thermal contact between the temperature sensor and the container, measuring the discharge rate in a discharge capacitor associated with the wireless communication device, and determining the maximum energy absorption frequency of the wireless communication device. The liquid level of the container may be determined by employing liquid level sensor techniques.
