Publication number: 20160317047Abstract: A vehicle seat includes sheet-shaped sensors configured to detect electric signals associated with the biopotential of a seated passenger, the vehicle seat being configured to remove noise caused due to static electricity to stably measure a bioelectric signal (e.g., heart rate) of the passenger. A seat back includes the sheet-shaped sensors. A cushion pad placed on a seat back frame is covered with a trim cover. Vertically-extending conductive fabric in a belt shape is disposed on an outer surface of the trim cover. The portion where the conductive fabric is disposed has a three-layer structure of the conductive fabric, a skin, and a wadding. A free end of the conductive fabric drawn into the seat back is provided with a J-hook hooked onto a lower frame bridging portion, thus part of the conductive fabric and the lower frame bridging portion contact each other to be electrically conductive with each other.Type: ApplicationFiled: December 25, 2014Publication date: November 3, 2016Inventor: Shinji Sugiyama

Publication number: 20160256096Abstract: An alertness device includes: a respiration sensor that obtains respiratory data of a person; a calculation unit; a waveform generation unit that generates a respiratory interval (RI) waveform which is a transition in a predetermined time period of an RI which is an interval for one respiration; and a determination unit. The calculation unit calculates an average value of the RI and RrMSSDn in a predetermined time period. In a case where an average value of the subsequent RI is greater than an average value of the RI directly previous to the subsequent RI and in a case where the RrMSSDn of the subsequent RI is greater than a value which is obtained by multiplying the RrMSSDn of the previous RI by a constant ?, the determination unit determines on the basis of values calculated by the calculation unit that the person is in a state of low alertness.Type: ApplicationFiled: October 20, 2014Publication date: September 8, 2016Inventors: Shinji Sugiyama, Takayoshi Ito, Kiyoko Yokoyama, Issey Takahashi
