Title (EN) CONTACT STATE ESTIMATING DEVICE, AND BIOLOGICAL SIGNAL MEASURING DEVICE
(FR) DISPOSITIF D'ESTIMATION D'ÉTAT DE CONTACT, ET DISPOSITIF DE MESURE DE SIGNAL BIOLOGIQUE
(JA) 接触状態推定装置及び生体信号測定装置
Abstract:
(EN) A contact state estimating device (1) which determines whether a measuring device for measuring a biological signal or the like is in a state of contact or a state of non-contact with respect to an object being measured is provided with: a first electrode (10a) and a second electrode (10b) which are brought into contact with an object being measured such as a living body; a direct current voltage supply unit (2); a signal switching unit (3) which switches between a first pathway whereby the direct current voltage supply unit (2) supplies a direct current voltage to the first electrode (10a) and an output signal from the second electrode (10b) is output, and a second pathway whereby the direct current voltage supply unit (2) supplies a direct current voltage to the second electrode (10b) and an output signal from the first electrode (10a) is output; and a contact state estimating unit (8) which estimates the state of contact of the first electrode (10a) or the second electrode (10b) with respect to the object being measured, on the basis of an output signal acquired at a time at which it is anticipated that pulse-type noise will occur concomitant with a signal switching operation to switch between the first pathway and the second pathway.
(FR) L'invention concerne un dispositif d'estimation d'état de contact (1) qui détermine si un dispositif de mesure destiné à mesurer un signal biologique ou similaire se trouve dans un état de contact ou un état de non-contact par rapport à un objet mesuré, comprenant : une première électrode (10a) et une seconde électrode (10b) qui sont mises en contact avec un objet mesuré tel qu'un corps vivant ; une unité d'alimentation en tension continue (2) ; une unité de commutation de signal (3) qui commute entre un premier trajet, l'unité d'alimentation en tension continue (2) alimentant la première électrode (10a) en tension continue et un signal de sortie provenant de la seconde électrode (10b) étant délivré, et un second trajet, l'unité d'alimentation en tension continue (2) alimentant la seconde électrode (10b) en tension continue et un signal de sortie provenant de la première électrode (10a) étant délivré ; et une unité d'estimation d'état de contact (8) qui estime l'état de contact de la première électrode (10a) ou de la seconde électrode (10b) par rapport à l'objet mesuré, sur la base d'un signal de sortie acquis à un instant où il est anticipé qu'un bruit de type impulsion se produira conjointement avec une opération de commutation de signal en vue de commuter entre le premier trajet et le second trajet.
(JA) 生体信号等を計測する計測装置が被測定対象物に対して接触状態にあるか非接触状態にあるかを判別する接触状態推定装置(1)は、生体等である被測定対象に接触される第一の電極(10a)及び第二の電極(10b)と、直流電圧供給部(2)と、直流電圧供給部(2)が第一の電極(10a)に直流電圧を供給し、第二の電極(10b)からの出力信号を出力する第一の経路と、直流電圧供給部(2)が第二の電極(10b)に直流電圧を供給し、第一の電極(10a)からの出力信号を出力する第二の経路とを切り替える信号切替部(3)と、第一の経路と第二の経路とを切り替える信号切り替え動作に伴うパルス性ノイズの発生が予想されるタイミングにおいて取得した出力信号に基づいて、第一の電極(10a)、または第二の電極(10b)の被測定対象に対する接触状態を推定する接触状態推定部(8)と、を備える。
