Abstract
A capacitive array is housed within a polyester mat or other appropriate nonconductive substrate material which is interconnected with a control module. The control module supplies to the capacitive array a suitable oscillator driver current and concurrently senses capacitance value changes within the capacitive array induced through dielectric shifts within the array brought about by the proximity or absence thereof of the patient's body mass. The monitor/control module generally comprises a power supply, a driver/sensor circuit, a calibration/comparator logic circuit, a system interconnection integrity circuit, and an alarm generation circuit. It may also optionally contain a nurse call relay circuit for interconnection to a facility's nurse call system.
