Electronic device for health index measurement and control method of the same
First Claim
1. An electronic device for health index measurement, comprising:
- a power receiving section that receives a power supply voltage, in which a digital code for performing a specific control is incorporated so that a low level voltage period of a predetermined length and higher than a minimum operating voltage of an electronic device is set before a period of incorporating the digital code, and said digital code begins with a high-level voltage after said low-level voltage period, and is expressed by a variation pattern of a combination of a high-level voltage and a low-level voltage;
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 the measured variation of a power supply voltage and to extract said digital code contained in the measured variation; and
a first control section configured to perform said specific control based on said digital code extracted by said signal extracting section.

Abstract
The present invention allows easily performing various types of controls and improving productivity without adding a special communication section. The present invention includes a power receiving section 21 to be connected to a driving power supply 50, a voltage measuring section 22 configured to measure a variation of a power supply voltage that is inputted to the power receiving section 21, a signal extracting section 23 configured to analyze measured data thereof and to extract a digital code contained in the measured data, and a control section 24 configured to perform a specific control based on the extracted digital code. As the specific control, the control section 24 selects an operation mode corresponding to the digital code from selectively executable plural operation modes, performs a function setting corresponding to the digital code, or writes the digital code as individual information into a nonvolatile memory.
