    • Provided are an alertness device configured such that a load is low in the processing for alertness determination and that the accuracy in alertness determination is high, a seat including the alertness device, and an alertness determination method. The alertness device includes a heart rate sensor configured to obtain an electrocardiographic signal of a person, a calculation unit configured to calculate the electrocardiographic signal obtained from the heart rate sensor, a waveform generation unit configured to generate an RRI waveform from an electrocardiographic waveform of the electrocardiographic signal, and a determination unit configured to determine the alertness of the person based on the electrocardiographic signal. The calculation unit replicates the same number of RRI waveforms as that of anchors, each anchor being a point where a certain RRI is shorter than the next preceding RRI. Then, the calculation unit moves the time axes of the replicated RRI waveforms such that the anchors of the replicated RRI waveforms are in phase with each other, and calculates a PRSA signal defined as an RRI average for each time axis. The determination unit determines the alertness of the person based on the RRIs and the PRSA signals.
    • 本发明提供一种清醒装置,该清醒装置被配置为使得在清醒度判定处理中的负载低并且清醒度判定的准确度高,包括清醒装置的座椅以及清醒性判定方法。 该清醒装置包括:心率传感器,被配置为获取人的心电信号;计算单元,被配置为计算从心率传感器获得的心电信号;波形生成单元,被配置为根据心电信号的心电波形生成RRI波形 心电图信号;以及确定单元,被配置为基于心电信号确定人的清醒度。 计算单元复制与锚点相同数量的RRI波形,每个锚点是某个RRI比下一个在前RRI短的点。 然后,计算单元移动复制的RRI波形的时间轴,使得复制的RRI波形的锚点彼此同相,并计算定义为每个时间轴的RRI平均值的PRSA信号。 确定单元基于RRI和PRSA信号确定人的清醒度。

    • A biosensor (100) includes: light emitting elements (121, 122) and a light receiving element (123) disposed on a principal surface (160a) of a wiring board (160); a light shielding portion (173) disposed between a light-emitting-element sealing portion (171) and a light-receiving-element sealing portion (172); a base medium (151) having light transmitting properties, disposed in parallel with the wiring board (160) with the light shielding portion (173) therebetween; an adhesion layer (180) having light transmitting properties, configured to bond the base medium (151) with the light-emitting-element sealing portion (171), the light-receiving-element sealing portion (172), and the light shielding portion (173); and a first electrocardiograph electrode (130) attached to a principal surface (151 a) of the base medium (151). Both end portions (184 and 185) of the adhesion layer (180) and both end portions (154 and 155) of the base medium (151) are disposed such that they overlap neither of the light-receiving-element sealing portion (172) nor the light-emitting-element sealing portion (171) when viewed from a direction (10) normal to the principal surface (160a) of the wiring board (160).
    • 生物传感器(100)包括:布置在布线板(160)的主表面(160a)上的发光元件(121,122)和光接收元件(123)。 设置在发光元件密封部分(171)和光接收元件密封部分(172)之间的遮光部分(173); 具有透光性的基底介质(151),与所述布线板(160)平行地设置有所述遮光部分(173); 具有透光性的粘合层(180),被配置为将基底介质(151)与发光元件密封部分(171),光接收元件密封部分(172)和遮光部分 (173); 以及附接到所述基底介质(151)的主表面(151a)的第一心电图仪电极(130)。 粘合层(180)的两个端部(184和185)以及基底介质(151)的两个端部(154和155)均布置成使得它们不与光接收元件密封部分(172)重叠, 当从与布线板(160)的主表面(160a)垂直的方向(10)观察时,发光元件密封部(171)也不发光。
