Abstract
An aspect of some embodiments of the present invention relates to a system configured for detecting connection between a pressure pad and a monitor. The system includes a pressure detection circuit and a presence detection circuit. The pressure detection circuit is configured for sensing whether the pressure on the pad is above or below the threshold pressure. The presence detection circuit is configured for determining whether a connection between the monitor and the pad is intact. The presence detection circuit is configured to establish a high voltage condition that occurs when connection is broken along the presence detection circuit and a low voltage condition when the presence detection circuit is intact.
