Definitions
- a device that irradiates a subject with light and measures living body related information
- the temperature of the site may increase. If there is a continuous temperature rise at the same site, heat transfer of the heat generating part becomes difficult, and a problem of thermal stress applied to the subject may occur.
- an alert may be output when the measured temperature exceeds a preset alert temperature. Accordingly, it is possible to notify that the temperature of the subject has exceeded the alert temperature during measurement, and to take action.
- FIG. 1A and 1B are perspective views illustrating a sensor module according to this embodiment.
- FIG. 1A shows a perspective view seen from the side opposite to the light emitting / receiving surface
- FIG. 1B shows a perspective view seen from the light receiving / emitting surface.
- FIG. 2 is a block diagram illustrating the configuration of the sensor module according to this embodiment.
- control unit 30 executes a stop process that stops in a state where the sensor module 1 cannot be restored by itself (a state in which the sensor module 1 cannot be restored) when the temperature measured by the temperature measurement unit 20 is equal to or higher than a predetermined value, that is, a shutdown.
- the shutdown state includes at least one of a state where power supply other than standby power is stopped and a state where execution of software related to measurement is stopped.
- the heat generation is lower in the shutdown state than in the state operating in the second mode.
- the light emitting unit 11 includes a drive circuit 11b that drives the first light emitting element 11a1 and the second light emitting element 11a2.
- the light receiving unit 12 includes an amplification circuit 12b that amplifies a light reception signal output from the light receiving element 12a. These circuits may be formed into chips.
- the light receiving element 12a receives light passing through the subject S and outputs a signal corresponding to the received light.
- the signal output from the light receiving element 12 a is amplified by the amplifier circuit 12 b and input to the control unit 30.
- the control unit 30 performs analog-to-digital conversion on the input signal and obtains signal outputs for each wavelength (760 nm and 850 nm).
- Calculation formulas and tables indicating the relationship between the signal output values and the values of the biological information are stored in advance in the memory 32 or the like.
- the calculation unit 31 performs calculation for estimating each biological related information according to the signal output value by referring to a calculation formula or a table.
- Time zone until start (because it is a time zone in which processing other than AD conversion can be performed, also referred to as “processable time zone”)
- a signal corresponding to near-infrared light of the first center wavelength ⁇ 1 is sent.
- a moving average process to be averaged is executed.
- the calculation unit 31 starts AD conversion of the signal corresponding to the near-infrared light of the next first center wavelength ⁇ 1 after the AD conversion of the signal corresponding to the near-infrared light of the second center wavelength ⁇ 2 is completed.
- a moving averaging process for averaging signals corresponding to near-infrared light having the second center wavelength ⁇ 2 is executed.

Abstract
Un module de capteur (1) selon un mode de réalisation de la présente invention comprend : une unité de réception/émission de lumière (15) qui est disposée sur un substrat (100), et qui comporte des unités électroluminescentes (11) pour émettre de la lumière d'une longueur d'onde prescrite vers un sujet, et une unité de réception de lumière (12) pour recevoir la lumière qui a traversé le sujet ; une unité de mesure de température (20) qui mesure la température du sujet ; et une unité de commande (30) qui est disposé sur le substrat (100), et qui est pourvue d'une unité de calcul pour estimer des informations biologiques sur la base d'un signal émis par l'unité de réception de lumière (12). L'unité de commande (30) dans le module de capteur (1) met en oeuvre une commande de telle sorte que : l'unité de réception/émission de lumière (15) et l'unité de calcul sont actionnées dans un premier mode lorsque la température mesurée par l'unité de mesure de température (20) est inférieure à une valeur prescrite ; et, lorsque la température est égale ou supérieure à la valeur prescrite, soit l'unité de réception/émission de lumière (15) et/ou l'unité de calcul sont actionnées dans un second mode dans lequel moins de chaleur est générée que lorsqu'elles sont actionnées dans le premier mode, soit un traitement d'arrêt est exécuté dans lequel le fonctionnement de l'unité de réception/émission de lumière (15) et/ou de l'unité de calcul est arrêté dans un état dans lequel l'auto-réinitialisation est désactivée.
