  • Publication number: 20240362470
    Abstract: The application provides a panoramic perception method, system and a non-transitory computer readable medium. The panoramic perception method comprises: performing a first pretraining on a plurality of weights of a training model using the source database; performing a second pretraining with data augmentation on the plurality of weights of the training model using the source database; performing a combined training on the plurality of weights of the training model using both the source database and the target database; performing a quantization-aware training on the plurality of weights of the training model using the source database and the target database; performing a post training quantization on the plurality of weights of the training model using the target database; and performing panoramic perception by the training model.

  • Patent number: 11650686
    Abstract: A unitarily white touch display comprises: a cover lens, a viewing area, from an upper surface to a lower surface of the cover lens, formed in the middle of the cover lens; a touch module disposed under the cover lens to provide touch functions; a light valve module disposed under the touch module and filled with a polymer dispersed liquid crystal layer; a microstructure optical film disposed under the light valve module, and a second surface of the microstructure optical film composed of a plurality of micro-prisms. When incident light enters the touch display, the incident light is scattered by the polymer liquid crystal module, and part of the incident light is reflected by the microstructure optical film, re-transmitted and scattered through the polymer liquid crystal module, so that a user can observe foggy white at the viewing area of the touch display.

  • Publication number: 20030118727
    Abstract: A method for fabricating carbon nanotubes having multiple junctions, comprising the process of supplying at least a substrate, metal powders, and carbon-containing reactant gas to chemical vapor deposition (CVD) system under high temperature. Carbon nanotubes having multiple junctions form above the substrate, thereby exhibiting two-dimensional and/or three-dimensional web-like structures with uniform diameters.
