Title (EN) HEARTBEAT MEASUREMENT DEVICE
(FR) DISPOSITIF DE MESURE DE RYTHME CARDIAQUE
(JA) 心拍測定装置
Abstract:
(EN) Provided is a heartbeat measurement device (1) comprising: a transmitter (3) for transmitting a transmission signal (St) from a transmission antenna (4) to a measurement subject (O); a receiver (5) for receiving, by a receiving antenna (6), a signal reflected from the measurement subject (O) as a received signal (Sr); and a quadrature detection circuit (7) for generating an I signal, corresponding to an in-phase component of the transmission signal (St) and the received signal (Sr), and a Q signal, corresponding to a quadrature component thereof. The heartbeat measurement device (1) further comprises: a Fourier transform unit (8) for calculating, from the I signal and the Q signal, positive and negative frequency region spectra (Ss); and a signal processing unit (9) for comparing the positive and negative frequency components of the spectra (Ss) and extracting a heartbeat component.
(FR) L'invention concerne un dispositif de mesure de rythme cardiaque (1) comprenant : un émetteur (3) pour émettre un signal d'émission (St) depuis une antenne d'émission (4) et jusqu'à un sujet de mesure (O) ; un récepteur (5) pour recevoir, par une antenne de réception (6), un signal réfléchi par le sujet de mesure (O) en tant que signal reçu (Sr) ; et un circuit de détection en quadrature (7) pour générer un signal I, correspondant à une composante en phase du signal d'émission (St) et du signal reçu (Sr), et un signal Q, correspondant à une composante en quadrature de celui-ci. Le dispositif de mesure de rythme cardiaque (1) comprend en outre : une unité de transformée de Fourier (8) pour calculer, à partir du signal I et du signal Q, des spectres de régions de fréquences positives et négatives (Ss) ; et une unité de traitement de signaux (9) pour comparer les composantes de fréquence positive et négative des spectres (Ss) et extraire une composante de rythme cardiaque.
(JA) 心拍測定装置(1)は、被測定者(O)に対し送信アンテナ(4)から送信信号(St)を送信する送信機(3)と、受信アンテナ(6)によって被測定者(O)から反射してきた信号を受信信号(Sr)として受信する受信機(5)と、送信信号(St)と受信信号(Sr)の同相成分であるI信号と直交成分であるQ信号を生成する直交検波回路(7)とを備えている。これに加え、心拍測定装置(1)は、I信号とQ信号から正と負の周波数領域のスペクトラム(Ss)を計算するフーリエ変換部(8)と、スペクトラム(Ss)の正と負の周波数成分を比較して心拍成分を抽出する信号処理部(9)とを備えている。
