Abstract: Provided are a smart surface, a center console of a vehicle, and a vehicle. The smart surface includes a display device (10), a decorative cover plate (20) including a decorative pattern layer (21), a substrate layer (22), an optical adhesive layer (23), and a glass layer (24) stacked sequentially from top to bottom, an upper surface of the glass layer (24) being fitted to the optical adhesive layer (23), and a lower surface of the glass layer (24) being covered on the display device (10), and an AG fluorescent film (30) fitted to the decorative pattern layer (21), and the AG fluorescent film (30) is used for filtering ambient light or light emitted from the decorative pattern layer (21). The smart surface provided by the present application can reduce the obstruction of the image caused by the decorative pattern by providing the AG fluorescent film.

Abstract: A method for optimizing a Polar-RNNA quantizer of MLC NAND flash based on deep learning comprises the following steps: Step S1: transforming an MLC flash detection task into a deep learning task, and obtaining three hard-decision read thresholds based on a neural network; Step S2: expanding six soft-decision read thresholds based on the three hard-decision read thresholds; Step S3: constructing an LLR mapping table, and obtaining new LLR information of MLC flash based on the LLR mapping table; Step S4: symmetrizing an MLC flash channel, and performing density evolution; and Step S5: optimizing the soft-decision read thresholds based on a genetic algorithm to obtain an optimal quantization interval. According to the invention, polar codes can be directly used for MLC flash channels without the arduous work of MLC flash channel modeling, so that the reliability of MLC flash is effectively improved.

Abstract: The invention relates to the technical field of textile printing and dyeing, in particular to a method for preparing yarn with cloud dyeing effect; dyes with more than one color are mixed, and a small amount of dispersing agent is added, so that the pigment is not completely uniformly mixed, and the yarn obtained by extrusion molding of the pigment mixed spinning raw material has a randomly distributed multi-color cloud dyeing effect, and the cloud dyeing yarn with multi-color cloud dyeing effect is prepared, and compared with the cloth blank prepared by the traditional single-color yarn, the prepared cloth blank has a more three-dimensional pattern effect.

Abstract: A preparation method of a jacquard sandwich fabric with a surface inlaid with yarns in reverse is disclosed, employing double-needle bar sandwich warp knitting machine, comprising the following steps: 1) reversely inlaying yarns; 2) re-defining the basic stitch of the jacquard, designing two basic stitches; 3) designing patterns using color (16) and color (20) according to the actual fabric needs, and drawing; 4) directly raising a pattern through a jacquard guide bar; 5) converting the designed pattern into a graphic diagram, and continuously modifying the pattern through the graphic diagram; 6) after finishing the pattern design, producing the finished fabric product. The fabric only has two basic stitches, and when designing the jacquard pattern, only color (16) and color (20) are needed for drawing, thus reducing half of the basic stitch color and reducing at least half the design steps.
