A contour shape measurement method that can more accurately align an article to be measured to a predetermined position to enable high-precision evaluation even in a state where a probe measurement axis and a table rotation axis do not match with sufficient precision is provided. A spatial position of the table rotation axis relative to the probe measurement axis is obtained as a rotation axis vector. Alignment data obtained in at least two directions is coordinate-transformed around the rotation axis vector, to constitute synthesized alignment data. The article is aligned based on the synthesized alignment data. Since three-dimensional data of a surface to be measured of the article can be calculated, the article can be directly aligned to the probe measurement axis.

The invention relates to a calibration device for a volume expansion measurement instrument of solid, and the device is provided with a hollow pedestal which is fixed on a front wall of a testing cavity of the expansion measurement instrument. The joint of the pedestal with the wall of the testing cavity of the expansion measurement instrument is sealed in a form of a static sealing structure through a second annular sealing ring. The cavity of the pedestal is provided with a first annular sealing ring in a sleeved manner. A rear screw of a pair of spiral micrometer heads is inserted into thecavity of the pedestal in a form of a moving sealing structure through the first annular sealing ring, and then the rear end of the screw is enabled to enter the testing cavity of the expansion measurement instrument in a threaded manner. The front parts of the spiral micrometer heads are provided with ratchet wheels, and the rotation of the ratchet wheels can drive the rear screw of the spiral micrometer heads to make reciprocating motion in the axial direction of the cavity of the pedestal. According to the invention, the internal environment of the testing cavity of the expansion measurement instrument is not changed before and after calibration, and the volume calibration can be carried out according to the needs. The device achieves the repeated calibration, and controls the random error. The device also has the capabilities of increasing the volume and reducing the calibration.

A method of determining the volume of organic material in a composting device includes rotating a mixing paddle in a composting bin that stores the organic material; monitoring the torque from a motor that rotates the mixing paddle as the mixing paddle rotates; and determining the height of the organic material in the composting bin based on the motor torque and the angular displacement of the mixing paddle. The resulting height can be used to determine the volume of the organic material.

The invention discloses an instrument and method for measuring the volume fissure rate of rock, and the instrument comprises a substrate, a skeleton, a fissure aiming device, a fixing device, and a hand-cranking device. A screw rod rotates under the action of the hand-cranking device, and drives the fissure aiming device on the fixing device to move up and down through threaded transmission. During measurement, the substrate is placed on the rack, and a plane where the substrate is parallel to an extending plane of fissures of a fissure group of a to-be-detected rock. A plane where a laser beam and a zero scale line on a calibrated scale on a side surface of the substrate is parallel to an extending plane of fissures of the fissure group of the to-be-detected rock, and one fissure of the fissure group of the to-be-detected rock is taken as the start point for the measurement from the bottom to the top. The true fissure width of each fissure in the fissure group and the distance between each fissure and the start point are recorded, wherein the measured fissure width is the true fissure width. The measurement data is accurate, and provides parameters for the calculation of the volume fissure rate of rock. The instrument is smaller in size, is light, and is portable. The application method is simple, so the instrument is suitable for the measurement of the volume fissure rate of outdoor rocks.

The present invention extends to methods, systems, apparatus, and computer program products related to a cable-based measuring system. The cable-based measuring system includes a cable, comprising an inner cable member configured to move linearly within an outer cable housing. The measuring system also includes a measuring device configured to generate measurement information regarding movement of the inner cable member relative to the outer cable housing using one or more encoders.
