A mat based antenna and heater system allows medical personnel to ascertain the presence or absence of objects ( e.g ., medical implements, sponges) tagged with transponders during medical procedures ( e.g ., surgery, labor and delivery), 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 and heater 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. The controller also operates one or more heaters or heating elements to selectively provide warmth to a patient. One or more sensors can detect temperatures at one or more locations, and the controller can use temperature readings in as feedback in controlling the heaters or heating elements. |
