Abstract: A method and an apparatus for waste liquid recycling with optical inspection are provided. The method includes: establishing a plurality of statistical criteria; capturing an image of a waste liquid in a transparent pipeline; performing image processing on the image of the waste liquid to obtain a plurality of characteristic data about a color characteristic; performing statistical calculation processing on the plurality of characteristic data to obtain a plurality of statistical characteristic values; and selecting at least one statistical criterion from the plurality of statistical criteria to compare with the statistical characteristic values so as to determine the quality of the waste liquid.

Abstract: A head mounted display (HMD) and an image generating method thereof are provided. The HMD includes a display device, an optical converter, an optical shutter and an optical engine. The display device receives an AR image and/or an external image, and transmits a display image along a projection direction. The optical converter receives the display image and adjusts an output angle to project an output image to a target area. The optical shutter opens a transmission path for the external image to the display device during a first time period, and inhibits the transmission path during a second time period, where the first time period is longer than the second time period. A first luminance of the AR image provided by the optical engine in the first time period is lower than a second luminance of the AR image provided by the optical engine in the second time period.

Abstract: The present invention provides a waste storage comprising a storage container, and an identification element. The storage container is utilized for storing a waste and the identification element disposed on the storage container has an identification information with respect to the waste. In addition, the present invention further provides a managing method and system which measure the characteristics of the waste stored in the storage container and then write the identification information associated with the waste in the storage container into an identification element disposed on the storage container, or generate an identification element having the identification information and then attach the identification element onto the storage container.

Abstract: The present invention provides a system for managing waste oil, which comprises at least one container wherein each container has an identifying element disposed thereon for recording information with respect to the waste oil provider, container, and quality of the waste oil. By means of the system, the present invention further provides a method for managing and trading the waste oil, which refers to a business method for implementing transaction such as sale of waste oil or exchange between waste oil and daily necessaries according to the information of the identifying element whereby the business center can control the logistics, cash flow and information flow easily and efficiently so that the waste oil provider can have service of transaction easily.
