摘要:
A biosignal measurement device is proposed which can improve measurement accuracy without forcing an excessive burden on subjects.A biosignal measurement device used for measurement of a biosignal in a head includes a support that can support the head, and an electrode provided to the support. The electrode has a plurality of teeth each including an annular portion in which a pair of linear members having conductivity are formed in an annular shape, and a rod-like portion in which the pair of linear members are wound in opposite directions and formed in a rod-like shape. The rod-like portion in each of the plurality of teeth is directly or indirectly fixed at one end to the support.

A fuel cell module includes in a casing: a fuel cell stack that is formed by stacking a plurality of unit cell; an oxidant gas distributing member that is disposed at a side surface, that extends in a stack direction of the unit cells, of the fuel cell stack that extends in a direction from one end to another end of each of the unit cells, and that supplies the oxidant gas to the another end of each unit cell after supplying the oxidant gas through the oxidant gas distributing member from the one end to the another end; a reformer disposed at the one end; and a combustion portion that is disposed between the one end and the reformer. The oxidant gas distributing member has a higher thermal conductivity at the one end side of the unit cells than at the another end side of the unit cells.

An information processor includes a brain wave sensor adapted to output a brain wave signal by measuring brain waves of a subject, an external sensor adapted to sense the surrounding environment of the subject, an environmental change determination section adapted to determine, based on a sensor signal output from the external sensor, whether a stimulus resulting from a change in the surrounding environment of the subject beyond a steady state has been applied to the subject, an event-related potential detection section adapted to detect an event-related potential for the stimulus in the brain wave signal if it is determined that the stimulus has been applied to the subject, and a calculation section adapted to calculate, based on a feature quantity obtained from the detected event-related potential, a value representing the focus level of the subject on a target.
