    摘要: A sensor node for intermittently sensing data in a short cycle includes a control unit for acquiring information by driving the sensor, a radio communication unit for transmitting the information acquired by the control unit and a battery for supplying the control unit. The control unit includes a clock supply unit (RTC) for supplying the control unit with clocks at a predetermined frequency. A sensor control unit starts the supply of power to the sensor when the measurement period has begun, maintains the power supply to the sensor even if the control unit has shifted to the standby state during the measurement period, and shuts down the power supply to the sensor when the measurement period has been completed. A measurement unit is also provided for acquiring information from the sensor every time the latter has shifted to the operational state.

    摘要: In a sensor node SN driven by a secondary battery, a charge/discharge control circuit can be realized and an unnecessary circuit in the sensor node can be eliminated for its miniaturization. The charge/discharge control circuit and the sensor node have a comparator for monitoring a battery voltage, a control circuit for converting an output of the comparator into an interrupt signal, a micro controller for performing charge/discharge control only when detecting the interrupt signal, and a switch turned ON or OFF under control of the micro controller. When the battery voltage is not lower than a first predetermined voltage, the switch is turned OFF to thereby stop charging operation. When the battery voltage is not higher than a second predetermined voltage, the switch is turned OFF to stop discharging operation. A circuit necessary in a charge mode is provided in a charger side.

    摘要: The precision of measuring biometric information is enhanced while suppressing the consumption of a battery in a sensor node. In a method of measuring the biometric information in a sensor node including a controller for driving a sensor to measure biometric information, the controller supplies power from a battery to an acceleration sensor for detecting the movement of a living body to detect the movement of the living body, the controller determines whether or not measurement by a pulsebeat sensor is possible based on the detected movement of the living body (P330), and shuts off power to the acceleration sensor having a power consumption lower than that of the pulsebeat sensor when the determination results show that measurement is possible, and thereafter supplying power to the pulsebeat sensor having a power consumption larger than that of the acceleration sensor to measure the biometric information (P340).
