  • Patent number: 10086559
    Abstract: A system for online monitoring powder-based 3D printing processes and method thereof are disclosed. A uniform light source having a single wavelength provided by the system is irradiated onto the powder layer before and after applied with glue. Intensities of such reflected images are obtained and subtracted from each other in an image process procedure. A difference obtained through the subtraction is compared with an original 3D model in a computer. If any defect is found such as being larger than a threshold value, the powder-based 3D printing processes will be terminated. Therefore, the technical effects of online printing processes monitoring, time saving and printing resources saving will be achieved.

  • Publication number: 20180085035
    Abstract: The present invention provides a detecting apparatus based on image for detecting blood glucose concentration and method thereof. The detecting apparatus comprising a lighting device, an image capture device, a thermal imager and an operating device. The lighting device including a first wavelength of light source and a second wavelength of light source, configured to illuminate skin. The image capture device disposed above the lighting device, configured to capture a first image and a second image corresponding to the first wavelength of light source and the second wavelength of light source illuminated on the skin respectively. The thermal imager is configured to detect temperature of the skin. The operating device is connected to the lighting device, the image capture device and the thermal imager, configured to calculate blood glucose concentration according to the first image, the second image and the temperature.

  • Patent number: 9269857
    Abstract: Disclosed are a method and system for eliminating yellow ring phenomenon occurring on the white light emitting diode (LED) based on a blue light chip exciting yellow phosphor powders and having a packaging surface enclosing thereon. Lightspot images are repeatedly acquired outside the white LED, and then each analyzed to see if the yellow ring still exists on a lightspot. If yes, a further atomization process is performed on the packaging surface of white LED, until the acquired and analyzed image shows no yellow ring exists. A lightspot-by-lightspot basis is used in the yellow ring elimination task. In the image analysis, a look up table may be provided in advanced or established at the same time simultaneously with the yellow ring elimination task. The atomization performed on the lightspot may also consider a width issue.
