Abstract: According to one embodiment, a substrate supporting apparatus includes a mounting plate that is configured by including ceramics and has a mounting surface on which the substrate is to be mounted; a power supply plate that is built in the mounting plate and electrostatically attracts the substrate to the mounting plate; a plurality of protruding portions which internally includes an electrically conductive member respectively, is arranged on at least a central region and outer edge region of the mounting plate, and protrudes from the mounting surface; and a plurality of elastic members which is embedded in the mounting plate to correspond to the plurality of protruding portions, supports the plurality of protruding portions while protruding the protruding portions from the mounting surface, and electrically connects the power supply plate and the electrically conductive members included in the plurality of protruding portions to each other.

Abstract: An object of the present invention is to provide an atrial fibrillation detection system in which: the extent of irregularity in measured pulse intervals is calculated; even in cases where an extrasystole has occurred, detection of a false positive is reduced even when the extrasystole is not excluded; and highly reliable assessment results are obtained.

Abstract: Provided is an atrial fibrillation detection system which can reduce the burden on a test subject, with which it is possible to detect even paroxysmal atrial fibrillation, and which can be used in the home, contributing to early detection of atrial fibrillation.

Abstract: The method for determining a depression state of the present invention comprises the steps of: measuring a pulsation interval of a subject, and an acceleration or an angular velocity associated with a movement of the subject (that is hereinafter referred to as an “activity”); and determining the subject to be a depression state when at least one of the following conditions [A] and [B] is satisfied: [A] In an awaking time zone of the subject, at least one of the following formulas is calculated and satisfied; the pulsation interval×the activity<C1, HF×the activity<C2, (LF/HF)/the activity>C3; [B] In a sleeping time zone of the subject, at least one of the following formulas is calculated and satisfied: the pulsation interval/the activity<C4, HF/the activity<C5, (LF/HF)×the activity>C6.

Abstract: The present invention provides a mobile electrocardiograph (ECG) apparatus in which: there is no need to provide a monitor or other display unit to an ECG unit, allowing the apparatus to be commensurately reduced in size and weight; the cost of operation is reduced through the use of a handheld electrode unit; and a body-surface-adhering electrode can be used in only cases when low-noise tests are required, thus promoting ease of handling.

Abstract: A method for preventing dozing off, comprising the steps of: a measurement step measuring human heartbeats; a decision step (S4 to S8) generating a trigger, hereinafter referred to as a “drowsiness trigger”, for indicating occurrence of drowsiness when a state in which a time interval between adjacent heartbeats, hereinafter referred to as a “heartbeat interval”, is longer than the previous heartbeat interval consecutively occurs; and a warning step (S9) giving a warning to prevent dozing off when the drowsiness trigger is generated.

Abstract: Provided is an atrial fibrillation detection system which can reduce the burden on a test subject, with which it is possible to detect even paroxysmal atrial fibrillation, and which can be used in the home, contributing to early detection of atrial fibrillation.

Abstract: Provided is a practical biological information measuring apparatus that is compact, provides minimal inconvenience worn on the body, and has an extended battery life, the biological information measuring apparatus being capable of instantly displaying a heartbeat interval.
