  • Publication number: 20190374205
    Abstract: This method for imaging in real time the propagation of a mechanical wave in an acoustically propagative medium comprises steps of: a) emitting (1000) a mechanical wave in an acoustically propagative medium, using an acoustic source being placed in an emission region of the acoustically propagative medium, b) measuring (1002) voltage signal waveform values at a reception region, using an acoustic measurement unit; c) calculating (1004) acoustic field values in the acoustically propagative medium, between the emission region and the reception region, using a reconstruction algorithm implemented in a signal processing unit, and the signal waveform values measured during step b) d) generating an image, using an image generation device and using the calculated acoustic field values.

  • Publication number: 20190104952
    Abstract: A blood pressure pulse wave measurement apparatus includes: first and second cuffs for pressing upper and lower limbs of a measurement subject; first and second detection units configured to detect first and second pulse waves transmitted from the cuffs through first and second tubes; and a control unit configured to calculate an ankle-brachial blood pressure ratio and a pulse wave velocity using the pulse waves. First and second delay elements are provided at specific positions in the lengthwise directions of the tubes. The first delay element delays a transfer characteristic of the first tube so the transfer characteristic of the first tube matches a transfer characteristic of a tube having a predetermined first reference length, and the second delay element delays a transfer characteristic of the second tube so the transfer characteristic of the second tube matches a transfer characteristic of a tube having a predetermined second reference length.

  • Publication number: 20190076034
    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).

  • Patent number: 10147009
    Abstract: In a display-object information displaying apparatus, each display object predetermined as a detection target is detected from image data captured by a front capture apparatus to capture of the front of a vehicle. A recognition failure probability that the driver fails to recognize each display object is evaluated. A memory saves the recognition failure probability and display object data containing display-object information with respect to each display object. A display unit displays the display-object information based on the corresponding display object data saved in the memory with respect to each display object. The display-object information about the display object assigned the higher recognition failure probability is displayed preferentially among the display objects corresponding to the display object data saved in the memory.

  • Patent number: 10030989
    Abstract: In a vehicle, positional information of the vehicle and status determination information are serially acquired. Each time a user speaks a speech, speech data is acquired. A storage section stores the acquired speech data, and the positional information and status determination information acquired when the speech data is acquired, in association in a memory, as stored speech data, stored positional information, and stored status determination information. For each stored speech data in the memory, a determination is made whether a first status indicated by the stored positional information and stored status determination information associated with the stored speech data is similar to a second status indicated by the positional information and status determination information newly acquired at a current time. A reporting processor reports, to a driver, information based on the stored speech data when the determination is affirmed.
