5results about How to "Achieve physical separation" patented technology

This utility model discloses an engineering vehicle and its chassis, including a chassis body, a winch, and a winch support. The winch is installed on the rear side of the chassis body in the forward direction, allowing the winch performing traction work behind the chassis body and the working device performing construction work in front of the chassis body to operate independently or collaboratively without interference, thus improving equipment utilization and work efficiency. The winch support is installed on the chassis body located behind the winch, and the winch support has a rope guiding structure to limit the rope released from the winch. This utility model enables convenient collection of logs while meeting load-bearing requirements.

This invention relates to the fields of computer data processing and database technology, specifically to an intelligent search system for business objects based on metadata. The system includes: a context request parsing module: receiving abstract search requests and extracting environment parameters and permission features to generate a dynamic context snapshot; a logical structure construction module: combining snapshot execution rule injection operations to generate a logical abstract syntax tree containing implicit filtering conditions; a multi-dialect compilation and execution module: translating the syntax tree into physical execution statements matching the target storage engine dialect according to physical mapping rules; and an adaptive optimization feedback module: monitoring execution latency data and dynamically correcting the index strategy definition. This invention solves the maintenance bottleneck caused by the tight coupling between business logic and physical storage in heterogeneous data source environments, achieving zero-code modification and hot deployment of business logic.

The invention discloses a heat pipe heat dissipation device based on air pressure driving. The heat pipe heat dissipation device comprises a heat conduction pipe and an air guide pipe. The heat conduction pipe is provided with an evaporation section and a condensation section which are mutually connected; the heat conduction pipe is provided with a containing cavity, the containing cavity extends to the evaporation section from the condensation section, and a working medium is contained in the containing cavity; the heat conduction pipe is provided with a capillary structure; the air guide pipe is arranged in the containing cavity and provided with a first channel, a second channel is arranged between the air guide pipe and the heat conduction pipe, and part of or all the capillary structures are arranged in the second channel. An inlet of the gas guide pipe communicates with the first channel and the evaporation section, an outlet of the gas guide pipe communicates with the first channel and the condensation section, and the gas guide pipe is provided with a one-way gas guide device. Physical separation of gas-liquid two-phase flow paths is achieved, and shear resistance generated by gas-liquid reverse flow in a traditional heat pipe is eliminated. And stable working medium circulation and heat transfer performance can be maintained in the horizontal direction and under the working condition along the gravity, and the applicability of the heat exchanger in various installation postures is effectively expanded.

This invention relates to the field of microscopy and discloses a light-sheet microscope system, comprising: a laser source for generating excitation light; a first optical element group for processing the excitation light into an initial light sheet; a beam splitting system for splitting the initial light sheet into multiple branch beams; multiple illumination objectives, each branch beam illuminating an independent illumination objective, with each branch beam through the illumination objective being uniformly arranged around the sample and all pointing towards the sample; a detection objective positioned below the sample; and a camera positioned in the imaging optical path of the detection objective. This system ensures that any point on the sample is illuminated by light sheets from at least two directions, effectively avoiding the problem of some areas in shadowed regions of large-sized samples, samples with poor transparency, or samples with asymmetrical complex structures. This not only improves image quality but also enables rapid scanning of large samples.
