摘要： This invention achieves lower electric power consumption of a sensor node for carrying out an intermittent operation, in a sensor net system. A time when the sensor node transmits a signal to a base station is estimated. Then, in accordance with the estimation, a table for storing a signal transmitted from the sensor node is installed in a wireless section of the base station. Consequently, a communication time between the sensor node and the base station can be made shorter. Also, a start time of a micro computer is set for RTC inside the sensor node, so the micro computer inside the sensor node can be put in the standby 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).
