Patent ID: 7361142

Claim:
An electronic device for health index measurement, comprising: a power receiving section that receives a power supply voltage into which a digital code expressed by a time-series voltage variation pattern is inserted for performing a specific control; a voltage measuring section configured to measure a variation of a power supply voltage that is inputted to said power receiving section; a signal extracting section configured to analyze data measured by the voltage measuring section and to extract said digital code contained in the measured data; a first control section configured to perform said specific control based on said digital code extracted by said signal extracting section; a second control section configured to perform a control for health index measurement and other necessary controls; and one switch section, or two or more switch sections configured to transmit a switching signal and other signals to each section by a predetermined setting operation, wherein said first control section has a function of performing a kind of control selected from plural kinds of specific controls by said digital code when receiving said digital code from said signal extracting section, and said second control section has a function of selecting a kind of control to be performed in said first control section in accordance with which switch section of said plural switch sections is operated and having it executed.
