Title:
DEVICE FOR IDENTIFYING CHANGES IN VERTICAL DIRECTION USING PRESSURE MEASUREMENT VALUES
Document Type and Number:
WIPO Patent Application WO/2014/192271
Kind Code:
A1
Abstract:
An identification device (100) is provided with: a vertical speed calculation unit (2) that calculates the vertical speed of a pressure measurement unit (1) from pressure values measured by the pressure measurement unit (1); a vertical speed determination unit (3) that determines the magnitude of the vertical speed; a vertical consecutive distance calculation unit (4) that calculates a consecutive distance moved in the vertical direction on the basis of the vertical speed calculated by the vertical speed calculation unit (2), and the determination result of the vertical speed determination unit (3); and a vertical movement determination unit (5) that determines whether or not the pressure measurement unit (1) has moved in the vertical direction according to whether or not the vertical consecutive distance calculated by the vertical consecutive distance calculation unit (4) is larger than a prescribed threshold value.
