Mat based antenna system to detect transponder tagged objects, for example during medical procedures
First Claim
1. A mat based antenna system for use in detecting transponder tagged objects which are used in performing medical procedures, the mat based antenna system comprising:
- a first sheet of an electrically insulative material that is sized to support at least a portion of a patient, the first sheet having an upper face and a lower face opposed to the upper face;
a plurality of antennas positioned successively along at least a portion of a length of the first sheet;
a first layer of silicon carried by the upper face of the first sheet;
a second layer of silicon carried by the lower second face of the first sheet;
a gel layer positioned relatively above the first layer of silicon with respect to the first sheet; and
a foam layer spaced relatively above the gel layer with respect to the first sheet.

Abstract
A mat based antenna system allows medical personnel to ascertain the presence or absence of objects (e.g., medical implements, medical supplies) tagged with transponders in an environment in which medical procedures (e.g., surgery) are performed, and may allow reading of information from the transponders, writing information to the transponders and/or controlling or commanding the transponders. In use, the mat based antenna system may be positioned beneath a patient, such as during surgery or child birth. A controller is coupled to the antennas to transmit signals (e.g. interrogation signals) to the transponders and to receive signals (e.g., response signals) from the transponders.
