  • Publication number: 20240070824
    Abstract: The present disclosure discloses an image processing circuit having output timing adjustment mechanism. An image enhancement circuit performs image enhancement on an input image to generate an enhanced image. A first image processing path and a second image processing path respectively perform processing on the enhanced image having a first timing and the enhanced image having a second timing to generate a first output image and a second output image. A timing control circuit adjusts the timing of the enhanced image according to requirements of the first image processing path and the second image processing path to generate the enhanced image having the first timing and the enhanced image having the second timing. A first image output interface outputs the first output image. A second image output interface outputs the second output image.

  • Patent number: 10219794
    Abstract: The invention relates to a method of treating pleural abnormalities in a subject in need thereof, comprising the steps of: (a) attaching a biodegradable polymeric membrane onto a pleural wound to elicit fibronectin from fibroblasts to cause fibrous adhesion; and (b) securing the membrane with securement products, including sutures, staples, and sealants. The present invention also relates to a biodegradable adhesion membrane used for treating pleural abnormalities, comprising: a biodegradable base material selected from the group consisting of polycaprolactone (PCL), polylactic acid or polylactide (PLA), polyhydroxybutyrate (PHB), poly(ethylene adipate), poly(butylene adipate) (PBA), chitosan, hyaluronic acid, and polyglycolic acid (PGA); wherein the thickness of the membrane is 0.1-1 mm.

  • Patent number: 9510733
    Abstract: An endoscope and a method for chemical modification of the members thereof are provided, on one hand, a transparent isolation film is utilized such that the tissue fluid inside a subject cannot stick to a lens of the endoscope to maintain the optimal image capturing status of the lens of the endoscope without the need to extract the endoscope frequently from the body of the subject, such that not only the time consumed in the examination process may be reduced, but also the uncomfortable feeling of the subject in the examination process may be decreased; on the other hand, a chemical modification method for members of the endoscope is provided to reduce the negative impact on the lens of the endoscope resulted from liquid pollutant or mist, moisture.

  • Patent number: 9103977
    Abstract: The present invention relates to a method for manufacturing a hard, water-resistant anti-fog coating, and particularly relates to a method for manufacturing a hard, water-resistant anti-fog coating on plastic material. In this method, an organic-inorganic hard adhesion layer and a hydrophilic anti-fog coating film are prepared for manufacturing a hard, water-resistant anti-fog coating. Both of the organic-inorganic hard adhesion layer and the hydrophilic anti-fog coating have C?C double bonds. Therefore, the organic-inorganic hard adhesion layer and the hydrophilic anti-fog coating are adhered to each other tightly. It brings high hardness, high water resistance and good anti-fog effect.

  • Publication number: 20150105708
    Abstract: A strap sticker for body adhesion is provided with an outer layer and an inner layer of different elastic coefficients, and an observation well running through both the inner layer and the outer layer, a well cross section profile of the observation well and a level for inner layer material coming out from the observation well changing with a force bearing status of a body of the strap sticker. Thereby, naked eyes may be used to identify directly a force bearing extension level of the strap sticker to meet the purpose of home use.
