    摘要： A method is provided of determining the internal cross-sectional area of a pipe along its length. The method includes the steps of: (a) filling the pipe with a first fluid; (b) feeding a second fluid into the pipe at a known flow rate, a meniscus being formed between the first and the second fluid, and the meniscus moving along the pipe as the second fluid displaces the first fluid in the pipe; (c) ultrasonically detecting the position of the meniscus as it moves along the pipe; and (d) determining from the second fluid flow rate and the meniscus position, the internal cross-sectional area of the pipe along its length.

    摘要： An area measurement device (200) having a support (202) to be moved around a boundary. A direction indicator (220) determines the directional orientation of the support (202) and creates direction data. A distance indicator (218) determines the distance traveled by the support (202) and creates distance data. A microprocessor (110) receives the direction data and distance data and calculates the area inside the boundary based on this data.

    摘要： A measuring device, such as a planimeter, having an increased measurable range for measuring a figure without increasing a length of the measuring device. The measurable range of a planimeter is based upon the a physical length of the planimeter. In order to increase the measurable range of the planimeter, the planimeter is provided with an operation control switch that functions to set a measurement mode of a computer associated with the planimeter to a suspend mode, temporarily halting a measurement operation, so that the planimeter can be shifted to another position. Thus, the measuring range of the planimeter is increased without increasing the physical length of the planimeter.

    摘要： A method and apparatus for measuring size distribution of bulk matter consisted of randomly orientated granules, such as wood chips, make use of scanning the exposed surface of the granular matter to generate three-dimensional profile image data defined with respect to a three-coordinate reference system, The image data is segmented to reveal regions associated with distinct granules, and values of the size-related parameter for the revealed regions are estimated. Then, a geometric correction to each ones of estimated size-related parameter values is applied, to compensate for the random orientation of corresponding distinct granules. Finally, the size distribution of bulk matter is statistically estimated from the corrected size-related parameter values.
