Title: APPARATUS AND METHOD FOR DETECTING THE CONDITION OF AN ITEM
Abstract:
The present invention relates to an apparatus and method for detecting the condition of an item and, particularly, but not exclusively, to an apparatus and method for detecting a specific condition of a motor vehicle tyre. The invention provides apparatus (4) comprising a structure for radiating radio frequency energy in response to a reception by said structure of radio frequency energy; said structure having a first configuration which, in use, is changed to a second configuration in response to said item attaining said specific condition; said change in configuration producing a detectable difference in radio frequency energy radiated from said structure. Apparatus according to the present invention thereby allows for the remote interrogation of the condition of an item.
