The objective of the present invention is to provide a hardness meter which estimates hardness in a stable manner regardless of a compression strength. Disclosed is a hardness meter characterized in being provided with: a movable portion which is continuously pressed against an object to be measured; a sensor which outputs an output signal reflecting a reaction force at a part of the object to be measured that is in contact with the movable portion; a motive force mechanism that causes the movable portion to perform a piston motion; and a hardness estimating portion which estimates the hardness of the object to be measured on the basis of an alternating current component of the output signal, generated by the piston motion of the movable portion.

According to the embodiments disclosed herein, in a press-fitting test for measuring physical properties of a test object by pressing an indenter against the test object and measuring the load and displacement, the measured displacement value is corrected in real time in consideration of the amount of deformation according to the load of the load cell, and thus an accurate load-displacement curve can be derived, even when the amount of deformation of the load cell is included in a measured value of a displacement sensor.

Capturing data in a drone enabled environmental for testing soil and ecological decision making includes initiating, using a computer, collection of data from multiple sources using a drone. The data includes information about soil at a specified soil location, in response to the drone flying over air space of a physical or geographical location respective to the soil location and/or landing at the soil location. Soil data is received, as part of the data, from the drone in response to testing the soil. The testing of the soil can include conducting a ground soil density test using a frangible probe. The data is analyzed to determine a best location for seeding and growing a plant in the soil.

An article orientation change device 30 includes a flap 11 is provided so as to be vertically swingable about a swing shaft 13 as a fulcrum, a conveying member 25 that pushes out a tablet W to a predetermined position on the placement surface 11a, and a pressing member 12 that presses the tablet W against the wall portion 1A, in which a tapered surface 25A is provided on a facing surface of the conveying member 25, the conveying member 25 conveys the tablet W to the placement surface 11a to push out the tablet W to the predetermined position in a state where the tablet W maintains the first orientation, and the pressing member 12 moves in a direction approaching the wall portion 1A to change an orientation of the tablet W on the placement surface 11a from the first orientation to a second orientation.

An object hardness measuring device includes a first side portion, a second side portion, a pedestal unit, a load unit, a measuring unit, and a holding unit. The load unit applies a load to the measurement object. The measuring unit is able to measure, in a state where the load acts on the measurement object, at least one of a movement distance of the second side portion with respect to the first side portion and a change amount of the load when the second side portion is moved either at a predetermined speed or to a predetermined position. The holding unit is able to hold the measurement object, and is movable between the first side portion and the second side portion by the slide rail unit.

This invention relates generally to geotechnical rig systems and methods. In one embodiment, a rig for sampling, includes, but is not limited to, a frame configured to deploy a drill string; at least one docking base disposed on the frame; at least one carousel with one or more addressed slots to stow one or more components, the at least one carousel being releasably coupled to the at least one docking base; and at least one arm that is configured to controllably retrieve and/or position the one or more components.

A method for obtaining a conversion relationship between dynamic and static elastic parameters includes: Step S1, acquiring horizontal cores at different depths of the destination formation; Step S2, measuring the dynamic elastic parameters of the horizontal core under different pressures; Step S3, measuring the static elastic parameters of the horizontal core under different pressures; Step S4, measuring the clay content of the horizontal core; Step S5 establishing a function relationship of the ratio between the dynamic and static elastic parameters with the formation pressure and clay content; and completing the conversion between the dynamic and static elastic parameters.
