Abstract: The present invention provides a device that allows a user to intuitively understand the activity of peristaltic movement of a gastrointestinal tract. Provided is a method for automatic measurement of peristaltic movement using a computer. The method includes: an acquisition step of acquiring measurement information about biological activity of one or more parts of a gastrointestinal tract; an extraction step of extracting information about activity of the peristaltic movement from the measurement information about the biological activity acquired in the acquisition step; and a calculation step of obtaining an activity score representing the degree of the activity of the peristaltic movement based on the information about the activity of the peristaltic movement.

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.

Abstract: Urine amount estimation device 100 is provided with ultrasonic sensor 1 which transmits ultrasonic waves into the body and which detects waves produced by reflection of ultrasonic waves; and estimating unit 52 which estimates the amount of urine in the bladder based on whether reflected wave W3 from the bladder detected by ultrasonic sensor 1 is present and/or based on the magnitude of reflected wave W3 from the bladder detected by ultrasonic sensor 1.

Abstract: A stool amount estimating apparatus includes: an ultrasonic sensor that detects a position of a wall of the urinary bladder; and an estimator that estimates a stool amount accumulated in a rectum based on an output of the ultrasonic sensor.

Abstract: An image pickup apparatus includes a plurality of micro pins provided to project from a back surface in an image pickup device, a plurality of electric boards capable of mounting electric components and having board surfaces provided with through-holes or through-grooves formed to enable the plurality of micro pins to pass through respectively, and solder portions that fix the plurality of micro pins and the plurality of electric boards by soldering in land portions adjacent to the through-holes or the through grooves in a state in which the plurality of electric boards with the plurality of micro pins respectively passed through the through-holes or the through-grooves of the plurality of electric boards are stacked on the back surface of the image pickup device.
