  • Publication number: 20200172010
    Abstract: A loudspeaker 14 outputs a warning sound for announcing the presence of a vehicle to the outside of the vehicle. A travel start detection unit 122 detects travel start of the vehicle. A sound pressure control unit 124 controls sound pressure of the warning sound to be output from the loudspeaker 14, depending on travel status of the vehicle. The sound pressure control unit 124 makes the loudspeaker 14 output the warning sound during stopping of the vehicle, and increases the sound pressure of the warning sound upon detection of travel start of the vehicle. This makes it possible to announce the travel start of a low-noise vehicle such as an electrically powered vehicle, without making the surroundings feel unnatural.

  • Publication number: 20200100695
    Abstract: A biological information measurement system includes a dewar, a single imaging device, and a hardware processor. The dewar covers a head of a subject and contains sensors that are arranged for detecting biological signals. The single imaging device acquires an image in which three or more reference points and the dewar are captured, the reference points being set in relation to the subject. The hardware processor is configured to: measure brain neural activity of the subject based on the biological signals detected by the sensors; determine positional relationships between the reference points of the subject and the sensors based on the reference points and positional relationship data of the dewar; and re-determine the positional relationships between the reference point of the subject and the sensors, based on images that are acquired by the single imaging device at different times.
