Claim Text:
1. A bed monitoring pad, comprising: a first flexible plate with conductive material; a second plate with conductive material; and a circuit between the first flexible plate and the second plate having a resistance between the first flexible plate and the second plate that indicates a useful life-time remaining for the bed monitoring pad and a risk of non-operation of the bed monitoring pad, wherein a value of less than 100 kΩ (kilohm) in the resistance in the circuit between the first flexible plate and the second plate when the bed monitoring pad is unoccupied indicates that the bed monitoring pad is faulty, wherein the first flexible plate comprises at least two zones of conductivity, each zone of conductivity configured to make some degree of physical and electrical contact with the second plate when a patient sits or lies on the bed monitoring pad.
