The device comprises a magnet steel which is arranged on an output shaft of a power plant, a non-conductive housing which is covered outside the output shaft of the power plant and the magnet steel and is connected with a sealing housing of the power plant in a sealing way, a steel column which is fixed onthe non-conductive housing and a sleeve which is arranged on the steel column. When the power plant in loading is entwined or blocked by a barrier under water, the device can still work normally, thereby avoiding the damage of the power plant and guaranteeing the service life of the power plant. In the invention, the magnet coupling connection is adopted to solve the problem that the power plant is difficult to seal in water. The power plant and the retarder are arranged in the same sealing box so that the complex moving seal is not needed on the output shaft; and the research, development and production ...

Three-dimensional finger vein recognition method and system

A three-dimensional finger vein recognition method and system, comprising the following steps: three cameras taking finger vein images from three angles to obtain three images; constructing a three-dimensional finger model according to finger contour lines; mapping two-dimensional image textures photographed by the three cameras into the three-dimensional finger model, respectively performing different processes on an overlapping region and a non-overlapping region; obtaining a three-dimensional finger vein image; and finally, performing feature extraction and matching on the three-dimensional finger vein image, to complete recognition. The method can acquire a better finger vein recognition effect, and has a higher robustness for a plurality of postures, such as finger rotation and inclination.

Substrate, maintenance method and display device

The present disclosure provides a substrate, a maintenance method thereof and a display device. The substrate includes a base substrate, the base substrate is provided with at least one conductive pattern, and at least one of the at least one conductive pattern is interrupted and divided into a first conductive sub-pattern and a second conductive sub-pattern. The maintenance method includes: coating a conductive material in an interruption region in such a manner as to cover both the first conductive sub-pattern and the second conductive sub-pattern; and coating an organic insulation material at a side of the conductive material away from the base substrate, and curing the organic insulation material to form an organic protection film covering the conductive material.

Power receptacle

A power receptacle includes a receptacle body having first snap slots, and an outer cover disposed over the receptacle body, having first snap hooks and second snap hooks. The first snap hooks detachably engage with the first snap slots. The receptacle further includes a reset button cap and a test button cap disposed on the outer cover, each cap having second snap slots which engage with the second snap hooks in a detachable and slidable snapping engagement. The snap engagements allow the outer cover to be conveniently installed on the receptacle body, and allow the user to depress the reset button cap and test button cap to activate the reset button and test button inside the receptacle. When the outer cover is worn or damaged, it can be conveniently detached from the receptacle body and replaced.
