WIRELESS LIVING BODY SENSOR

摘要

PROBLEM TO BE SOLVED: To reduce communication trouble generated accompanied by a change in the sleeping posture of a user while suppressing power consumption in a living body data measuring instrument having a transmission function.SOLUTION: A test signal containing the posture data of the user is preliminarily transmitted from a wireless living body sensor by a predetermined transmitting power. A receiver receiving the test signal forms a transmission power pattern wherein proper transmission power and the posture of the user are related to each other from a relation between a receiving power and the posture information of the user and the generated transmission power pattern is copied on the wireless living body sensor. The wireless living body sensor refers to the internally stored transmission power pattern and transmits the living body data by a proper transmitting power according to the posture of a person estimated by the sensor to suppress power consumption while reducing communication trouble.
