  • Patent number: 8436494
    Abstract: A touch sensor device comprises: a touch sensor 1 for sending out an output voltage signal S1 representing the presence or absence of an operation; an operation presence/absence determination unit 2 which, when the output voltage signal has a value equal to or more than a predetermined threshold value, determines that the operation has occurred; a stability determination unit 5 for detecting whether a differential signal S3 representing a differential value obtained by differentiating the output voltage signal is limited within a predetermined range or not; and a count-up timer 4 which, when a period during which the differential signal is limited within the predetermined range becomes a predetermined time period or longer on the premise that the output voltage signal has the value equal to or more than the predetermined threshold value, sends out an ON determination signal S5 and allows an external device 7 to operate.

  • Patent number: 5574641
    Abstract: An apparatus and method for detecting heartbeat pulse information of a driver, including determining a level of awareness of the driver from the heartbeat pulse information, detecting a steering angle of the vehicle, determines the level of awareness, of the driver from the steering angle and activating at least one warning according to the level of awareness of the driver.

  • Patent number: 5488353
    Abstract: An apparatus and method for a driver of a vehicle in which a level of awareness of the driver is determined, and compared with a reference value to determine a decrease in awareness. A warning is generated when driver awareness is low. The driver responds by terminating the warning. The reference value of the awareness determination means is corrected according to a response time of the driver to the warning.
