Abstract: System and method that use a pressure sensitive mat to monitor vitals signs of an individual positioned on the pressure sensitive mat. The pressure sensor mat is coupled to pressure sensors that each have an adjustable pressure responsivity. In order to be able to monitor the vital signs without interruption due to the individual repositioning themself on the pressure sensitive mat and thereby running the risk of increasing the pressure on some pressure sensors to the point of saturation, or running the risk of decreasing the pressure on other pressure sensors to the point losing any usable signal, the system comprises circuitry that monitors a baseline pressure sensor at one pressure sensor and controls, as a function of the monitored signal, the pressure responsivity at a neighbor pressure sensor. This allows the neighbor sensor to generate a monitored signal with discernable time dependent features associated with the individual's vital signs.
