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.
