Abstract: Intelligent VR (Virtual Reality) elastic bandage equipment includes a main body, left and right supporting arms, a rear support, a telescopic assembly and a driving mechanism. According to a touch panel in the equipment, different input signals are triggered through different touch actions and touch durations, and a motor is controlled through a main control circuit board, so that the motor outputs different rotating speeds and directions; and therefore, the motor further drives the driving mechanism to drive the telescopic assembly to move and stretch, the telescopic assembly further drives the left and right supporting arms to retract, and adjustment of the distance between the main body and the head of a human body is achieved, so that the equipment is more comfortable to use, the use range is enlarged, and the operation is easy.

Abstract: A semiconductor memory comprising: a comparison readout circuit comprising a first port configured to receive an electric signal of a read memory unit and a second port configured to receive a reference electric signal, the comparison readout circuit being configured to compare the electric signal of the read memory unit with the reference electric signal to obtain storage information of the memory unit; and a first/second column decoder connected to a first/second memory array and the comparison readout circuit and configured to select a bitline corresponding to the read memory unit when a memory array selection signal enables the first/second memory array, and output the electric signal of the memory unit to the first port by means of the bitline, and further configured to connect a first bitline of the first/second memory array to the second port when the memory array selection signal does not enable the first/second memory array.

Abstract: A field wheat stem tillering number extraction method, including: acquiring field wheat point clouds by means of a LiDAR, and extracting any row of wheat point clouds in a research area; projecting a Y axis to a plane, and retaining an X and Z axis; applying adaptive layering to obtain number of clusters of the wheat row; applying hierarchical clustering analysis to obtain tillering number of each wheat cluster; and further obtaining stem tillering number of the whole wheat row, so as to extract a field wheat stem tillering number. The feasibility of an algorithm is verified by comparing the wheat stem tillering number extracted by means of the method with an actually measured field stem tillering number, and the method realizes rapid, accurate and nondestructive extraction of a large-field crop stem tillering number and provides theoretical basis and technical support for extraction of the field wheat stem tillering number.
