    摘要: A non-invasive ultrasound detection device for detecting liver fibrosis and method thereof is disclosed. The method comprises the steps of: creating a discriminant function of several parameters, each with a weight obtained by LDA, based on a database; and determining the degree of liver fibrosis by comparing a reference value and a numerical value calculated from the discriminant function. The parameters represent different probability distribution functions capable of identifying liver fibrosis or fatty liver. In the step of creating a discriminant function, the database provides the processed data based on numerous ultrasound images of patents' livers for LDA. In the step of determining the degree of liver fibrosis, the processed data based on ultrasound images of a person's liver are obtained for further calculation of the numerical value. The processed data includes an average value for each probability distribution function within an area corresponding to a liver.

    摘要: A robot using a liquid crystal display panel includes a mask, an LCD panel and a high-directional backlight module. The LCD is arranged close to the mask, and the backlight module is arranged on one side of the LCD panel and used to provide an extremely high directional backlight source to the liquid crystal display panel so that the image generated by the LCD panel can be projected onto the mask. By projecting images on the mask via the LCD panel, the disadvantage that the conventional projector needs to occupy a larger space is improved, and the design of the mask can be more flexible.

    摘要: A spectral analysis device is provided herein. The spectral analysis device includes a first lens, a transmission grating, a lens set and a sensing element. The first lens is configured to receive and converge an incident light beam into a first light beam. The transmission grating is configured to disperse the first light beam into a plurality of second light beams. The lens set is configured to receive the plurality of second light beams. The sensing element includes a substrate and a plurality of pixels. The plurality of pixels is configured to respectively receive the plurality of second light beam. Such structure is used to analyze the spectrum of incident light.
