Recording tag and reading system
First Claim
1. A self-contained tag for use with an article for sensing one or more conditions associated with said article, said tag including power means, condition sensing means, transducer means, information storage means, and information transmission means, whereby said transducer means converts a condition sensed by said sensing means into a signal that can be stored by said storage means for eventual transmission to a reader.

Abstract
A tag that can be mounted to or within an article has means for sensing one or more conditions associated with the article, such as temperature, shock, radiation or atmosphere. The tag also includes power means such as a thin film battery, transducer means, data storage means, and means for transmitting data or information to a suitable receiver. The tag will accompany the article in transit or in storage and be able to inform an interested party of conditions experienced by the article. The tag can be programmed to sense conditions at specific time intervals, making use of an internal clock. The clock, data storage means, transducer means and transmission means can all be part of a thin film integrated circuit incorporated on the tag.
