Waterproof power socket based on electromagnetic control and capacitance change

The invention discloses a waterproof power socket based on electromagnetic control and capacitance change. A socket relates to the technical field of electric power and comprises a socket body, two symmetrical first springs are fixedly connected to the inner bottom wall of the socket body, a movable electric block is fixedly connected to the tops of the first springs, a dielectric plate is fixedlyconnected to the middle of the movable electric block, and two symmetrical positive plates are fixedly connected to the inner wall of the middle of the socket body and close to the inner side of themovable electric block. The invention discloses a waterproof power socket based on electromagnetic control and capacitance change. The rubber sleeve is matched with the waterproof groove for use; whenthe plug is plugged into the socket, the rubber sleeve can expand upwards under the extrusion effect of the arc-shaped plate; and the rubber sleeve is tightly attached to the waterproof groove, and the rubber sleeve completely wraps the joint of the plug and the socket, so that a waterproof effect is achieved, water is effectively isolated from the socket, the water is prevented from entering thesocket, safe use of power equipment is ensured, and the service life of the power equipment is effectively prolonged.

Polarization maintaining optical fiber with small bending radius and manufacture method of polarization maintaining optical fiber

The invention discloses a polarization maintaining optical fiber with a small bending radius and a manufacture method of the polarization maintaining optical fiber and relates to the field of optical fiber manufacture. The polarization maintaining optical fiber comprises a silica cladding, a core layer, a second silica cladding ring, a third fluorine-doped silica cladding ring and two stress cat eyes are sequentially arranged in the silica cladding from inside to outside, and the two stress cat eyes are in central symmetry with the core layer. By means of the manufacture method, the bending radius of the manufactured polarization maintaining optical fiber is smaller than 5mm, operating wavelength of the polarization maintaining optical fiber is 1550nm, and supplementary deterioration of the polarization maintaining optical fiber is under 0.4dB/km. According to the polarization maintaining optical fiber, under the condition that the bending radius is small, low-loss information transmission of the polarization maintaining optical fiber is achieved, low supplementary deterioration and good crosstalk characteristics of the polarization maintaining optical fiber are guaranteed, fiber optic sensors with small sizes can be manufactured by means of the polarization maintaining optical fiber, and requirements of users are satisfied.

Polarization multiplexing holographic imaging method based on transmission type all-medium metasurface

The invention belongs to the technical field of micro-nano optics, polarization optics and optical holographic, and discloses a polarization multiplexing holographic imaging method based on a transmission type all-medium metasurface. A response main wavelength <lambda> is determined; geometric parameters of a unit structure are determined; a GS phase recovery algorithm is adopted to obtain phase distribution of the unit structure responding to the main wavelength; the pixel point of each element is expanded into a 2*2 array by adopting a Dammann grating method, and the obtained each pixel unitcomprises information responding to horizontal polarized light and information responding to vertical polarized light; and a synthesized silicon nano-antenna array is irradiated by horizontal polarized light and vertical polarized light with the wavelength of <lambda>, and different holographic images are reconstructed. According to the method, phase modulation of 0-2 <pi> can be realized only bychanging the size of the short axis of the silicon nano-antenna, and an embossment phase modulation structure of any step number can be realized equivalently; and a simple process, high processing error tolerance and quite high stability and reliability are achieved.

File scanning method and file scanning device and file detecting system

The invention discloses a file scanning method, a file scanning device and a file detecting system, so that a problem that scanning again needs a long time is solved. The file scanning method comprises the following steps: acquiring current attribute information of a to-be-scanned file; visiting a local cache database, and judging if scanned feature information of the to-be-scanned file exists in the local cache database; if the scanned feature information of the to-be-scanned file exists in the local cache database, then analyzing the scanned feature information to obtain scanned attribute information, and judging if the scanned attribute information is identical to the current attribute information; if the scanned attribute information is identical to the current attribute information, then reading the scanned feature information to serve as current feature information of the to-be-scanned file; and if the scanned attribute information is not identical to the current attribute information, calculating the current feature information of the to-be-scanned file through the current attribute information, and storing the current feature information of the to-be-scanned file on the local cache database to serve as scanned feature information for the next scanning. According to the file scanning method, the file scanning device and the file detecting system, time for acquiring the same file features of the next scanning can be reduced, and the speed of file scanning is improved.
