This invention discloses a color enhancement method for a single phosphor wheel architecture, comprising a projector using a single phosphor wheel. This projector does not have a color wheel; yellow (Y), red (R), and green (G) are all generated from the phosphor wheel and produced by laser irradiation of phosphors. Blue (B) is generated from the optical path behind the phosphor wheel by creating a hole in the phosphor wheel. The laser irradiation occurs in the optical path system where a blue laser excites the phosphor. The red (R) phosphor produced after irradiation has a poor effect, with a color bias towards orange. Without changing the single phosphor wheel architecture, the color coordinates of red (R) are improved by adding a glass filter to the surface of the red (R) phosphor. To improve the color of a single phosphor wheel, this invention requires adding a filter to the area where color improvement is needed. However, the added filter's refractive index and thickness cause the original focal point to shift backward. This is compensated for by locally processing an aluminum sheet to correct the shift in focal point, allowing each color to achieve its optimal color coordinates and efficiency.

This invention discloses a camera focusing mechanism and module based on an ultrasonic micromotor structure, belonging to the field of camera focusing mechanism design. It includes a piezoelectric thin film-driven ultrasonic micromotor, a sloping driven structure, a spring structure, and a housing with a slotted structure and a housing protrusion structure. When the stator structure of the ultrasonic micromotor generates a standing wave or traveling wave under the excitation of an external signal, the stator protrusion structure undergoes elliptical motion. This elliptical motion drives the friction layer, magnetic material layer, and sloping driven structure in the rotor structure to rotate. During rotation, the rotational direction is constrained by the cooperation of a limiting post and the slotted structure, while the sloping driven structure moves linearly along the optical axis. The housing protrusion structure and the outer edge of the rotor structure provide planar positioning. This invention achieves higher adjustment accuracy and faster response speed, making it more suitable for embedding in camera module structures of mobile phones and other terminal applications.

The present application relates to the technical field of knowledge graph, specifically to a fire-fighting equipment safety evaluation optimization method based on big data, comprising the following steps: firstly, fusing static building information and real-time data of Internet of Things, and constructing a space-time knowledge graph containing facility entities and logical relationships; secondly, using a hidden Markov model and Viterbi algorithm to decode historical sequences and obtain real hidden state sequences; thirdly, introducing betweenness centrality as an attention gain factor in graph neural inference, calculating node risk entropy and locating risk transmission paths; fourthly, searching initial strategies through subgraph isomorphism matching, and constructing a multi-objective dynamic optimization model containing risk, cost and time; and finally, using a gradient-based conflict resolution mechanism to correct the search direction. The method realizes dynamic decoupling and efficient management of multi-dimensional coupled risks of fire-fighting equipment in complex building scenarios.
