  • Publication number: 20210085289
    Abstract: An ultrasonic measurement device includes: a probe configured to be attached to a body surface of a subject while being in contact with the body surface, transmit ultrasonic waves into a body of the subject, and receive reflected waves of ultrasonic waves; and a controller configured to determine a contact state of the probe with the body surface. The controller determines the contact state of the probe with the body surface by comparing at least two received signals acquired through transmission and reception of ultrasonic waves by probe at different times.

  • Patent number: 4365307
    Abstract: A temperature pattern measuring device for obtaining the surface temperature distribution of an object. The device receives an image of the measured object and two different wavelength components of light emitted from the object. The device performs a two color temperature process for each minute area within a visual field of the image pickup, detecting the temperature at a portion on the surface of the corresponding measured object, thereby obtaining the temperature pattern thereof. The above minute areas can be set by an electrical method using photoelectric conversion means. Also, a supervision unit for the weld zone at an electrically seamed pipe, may employ the temperature pattern measuring unit of the present invention, the supervision unit producing a composite display of the form of the weld zone and the temperature pattern thereof.
