  • Publication number: 20240083459
    Abstract: In a technique for controlling a first vehicle, display information and position specifying information are received from a second vehicle different from the first vehicle via inter-vehicle communications. The display information is information for display and independently set for the second vehicle in the second vehicle. The position specifying information is information for specifying a position of the second vehicle. The position of the second vehicle relative to the first vehicle is specified based on the position specifying information. Display on a display device is controlled to superimpose information indicated by the display information on the position of the second vehicle in a landscape in front of the first vehicle based on the position of the second vehicle and the display information.

  • Patent number: 11432728
    Abstract: This blood pressure/pulse wave measurement device obtains a pulse wave velocity (baPWV) that is an index representing the arterial stiffness of a subject. A lower limb/upper limb blood pressure ratio (ABI) that is an index representing the clogging of the blood vessels of a subject is obtained. When the lower limb/upper limb blood pressure ratio (ABI) of the subject surpasses a preset first threshold value, a point (Px) representing the pulse wave velocity (baPWV) is displayed on a one-dimensional graph (46). When the lower limb/upper limb blood pressure ratio (ABI) of the subject is equal to or less than the preset first threshold value, a point representing the lower limb/upper limb blood pressure ratio (ABI) is displayed on the one-dimensional graph (46) instead of the point representing the pulse wave velocity (baPWV).
