The disclosure relates to agricultural systems. The systems have stalk sensor assemblies and/or data visualization systems. The stalk sensor assemblies are configured for assessing the size and other characteristics about crops, such as corn and other grains entering an agricultural implement, such as a harvester. The stalk sensor assemblies may use an estimation of the stalk perimeter to establish stalk size and therefore further features about the crop. The visualization system utilizes data from the stalk sensor assemblies to calculate and display relevant information about the crop.

Disclosed herein are various devices, systems, and methods for use in agricultural, particularly for use in harvesting agricultural crop such as corn. Various implementations relate to methods and devices for measuring plant stalk cross-sectional area during harvest and providing additional methods of predicting and displaying yield on a row-by-row level in real time.

A workpiece diameter measurement method includes: detecting positions of a probe while relatively rotating an uncalibrated standard and a detector around a rotation center in a state where the probe is in contact with a circumferential face of the standard from one side in a displacement direction of the probe, detecting the positions of the probe while relatively rotating the standard and the detector around the rotation center in a state where the probe is in contact with the circumferential face from another side in the displacement direction, calculating the position of the rotation center based on the detected positions, relatively rotating a workpiece and the detector around the rotation center in a state where the probe is in contact with the workpiece from the other side, and calculating a diameter of a circumferential face of the workpiece.

An apparatus, system, or method for performing work on electrical power lines and/or splices on electrical power lines that may include an unmanned aerial vehicle (UAV), a power line measurement device, a support frame selectively releasably attached to the UAV, and a plurality of flexible dielectric attachment lines attaching the power line device to the support frame.

An apparatus for checking the diameter of crankpins (15) of a crankshaft in orbital motion about a geometrical axis in a numerical control machine tool includes a V-shaped reference device (10), a measuring device (6) and a support device (4) fixed to the tool holding slide (2) that movably supports the reference device and the measuring device. A control device (50) for controlling automatic displacements of the apparatus towards and away from a checking condition, includes a programmable electric motor (60) and a transmission mechanism (62). The programmable electric motor is programmed to define a start position in which the automatic displacement of the apparatus away from the checking condition can be stopped, for instance a rest position or an intermediate position between the rest position and the checking condition. The programmable electric motor is also programmed to define a displacement speed and a checking method includes steps for controlling the automatic displacements towards the checking condition.

A method for estimating the external radius R.sub.e of a tire fitted to a wheel of a motor vehicle, the wheel including a radial acceleration sensor. The method includes: acquiring, by the sensor, a signal S when the vehicle is in motion under non-steady-state conditions, detecting local extrema of the signal S which are respectively associated with phase values and with detection instants, determining a variation in frequency F′ of rotation of the wheel as a function of said phase values and of said detection instants, determining, for at least one detection instant, a discrepancy between the local extremum associated with said detection instant and a reference signal obtained by eliminating the fluctuations in the signal S, determining a value for the longitudinal acceleration V.sub.al of the vehicle as a function of the at least one discrepancy, estimating the external radius R.sub.e as a function of V.sub.al and F′.
