Abstract:
본 발명은 차량 등과 같은 환경에서 피험자의 자세의 변경 등을 적절히 감안하여 피험자로부터 측정된 BCG신호를 적절히 분석할 수 있도록 함으로써, 피험자 신체상태의 정확한 진단이 가능하도록 하고, 그에 따라 차량 등에서 피험자에게 안마 기능을 제공하거나 실내 환기를 시키는 등의 적절한 후속조치가 가능하도록 하여, 차량의 상품성을 극대화시킬 수 있도록 한다.
Abstract:
PURPOSE: A system and a method for observing the heart rate of passengers are provided to periodically evaluate the optimal signal among multiple signals, thereby obtaining a correct heart rate. CONSTITUTION: A plurality of heart rate detection sensors (500) is composed of different kinds. The heart rate detection sensor is provided to a seat cushion (300) or a seat back (100). The heart rate detection sensor comprises an electrocardiogram sensor (510). A control unit produces the accuracy of each waveform. The control unit calculates a heart rate with the most accurate waveform.
Abstract:
The present invention enables an accurate diagnosis of subject body condition through a proper analysis of BCG signals measured from a subject by appropriately considering posture changes of the subject, etc. in an environment like a vehicle, etc., and enables appropriate follow-up actions such as providing a massage function for the subject, ventilating the interior, etc. to be taken in a vehicle, etc. according to the diagnosis, thereby maximizing the marketability of a vehicle.
