This paper evaluated a bed occupancy monitor system, which we proposed previously. In particular, the validity of the system was investigated using testing data. The system, employing capacitively coupled electrodes, converts change in load into change in capacitance. The capacitor was involved in a CR oscillation circuit, and the change is finally converted into voltage using a frequency-voltage converter. The results of the investigation revealed that the accuracy of the algorithm for thedoi:10.9746/sicetr.50.622 fatcat:rqukrcbhb5gxjbk673kjwpudai
