5results about How to "Eliminate dispersion" patented technology

This application discloses a dynamic form construction method, device, and medium, relating to the fields of software engineering and enterprise application development technology. The method includes: receiving a form request containing a view model identifier and request type based on a preset view parsing and execution engine; parsing a predefined view model according to the identifier to obtain its metadata, which defines the target business entity, view data object structure, field set, and filtering conditions; for data query requests, dynamically constructing and executing SQL statements based on the aforementioned metadata, obtaining raw data, performing aggregation and transformation, and generating structured view data that meets the front-end rendering requirements for return; for data submission requests, converting the data submitted from the front-end back into domain model data according to the same view model, and calling the business entity engine service to complete business logic verification and persistent storage, thereby achieving dynamic generation of the form view, decoupling of front-end and back-end logic, and ensuring business consistency.

A vehicle door welcome lamp comprises a lens cone, an imaging set, a film set and a light condensation set are sequentially arranged in the lens cone from inside to outside, the imaging set comprises 3-5 lenses, the 3-5 lenses of the imaging set at least comprise a concave lens and a convex lens, and the light condensation set comprises 1-2 lenses; the film group comprises a film clamp and a film, the film is clamped on the film clamp, and the film clamp is located between the third lens and the film. The three convex lenses and the concave lens are adopted to form the lens group, dispersion and other chromatic aberration are effectively eliminated, the field angle of the lens group can reach 30-60 degrees, and the lens group is provided with the condensation group, the film group and the imaging group, can be suitable for multiple scenes and is high in compatibility.

An automobile welcome lamp with three module lenses comprises a shell, a light condensing system, a film module and an imaging system, a light condensing lens mounting cavity, a film module mounting cavity and an imaging lens mounting part are sequentially arranged in the shell in the light emitting direction, the light condensing system is mounted in the light condensing lens mounting cavity, and the film module mounting cavity is mounted in the imaging lens mounting part. The film module is mounted in the film module mounting cavity, and the imaging system is mounted in the imaging lens mounting part; the condensing system comprises a condensing lens mounting seat and three condensing biconvex lenses, and the condensing biconvex lenses and the condensing lens mounting seat are connected to form an integrated structure; the film module comprises a glass film, and three groups of film patterns are arranged on the glass film; the imaging system comprises a first imaging module, a second imaging module and a third imaging module which are sequentially arranged in the light emitting direction, and the first imaging module, the second imaging module and the third imaging module are independently placed in the imaging lens installation part. The device is compact in overall structure, small in occupied space and small in size, can adapt to multiple scenes, can effectively eliminate chromatic dispersion and other chromatic aberration, and is high in practicability.

The invention relates to a log desensitization method, system and device capable of dynamically updating rules and a program product. The system comprises a configuration management center and a log desensitization agent. And the configuration management center is used for centrally storing and managing the desensitization rules and actively sending update notifications to the associated agents after the rules are modified. The log desensitization agent is packaged into a Java Agent, and parameter loading is started through the JVM of the target service application. When the application is started, the agent implants desensitization logic into the log output class through a byte code enhancement technology; the method comprises the following steps: acquiring an initial rule from a configuration management center and caching the initial rule in an own memory; and when a rule updating notification is received, dynamically pulling a new rule and updating the memory, so that the rule takes effect in real time. And when the business application runs, the agent carries out desensitization processing on the log output according to the latest rule in the memory.

The invention relates to the technical field of ultrashort pulse time domain sampling, in particular to a total reflection type collinear ultrashort pulse time domain sampling device and method, by adopting a total reflection type light path design, all key optical elements work based on a reflection principle, the dispersion problem introduced by a transmission element is fundamentally eliminated, and the time domain sampling accuracy is improved. Therefore, the original time domain and frequency domain characteristics of the to-be-measured pulse can be kept in the measurement process, the high fidelity and reliability of the measurement result are ensured, the overall structure is simple, operation is convenient, and the working efficiency is improved.
