  • Patent number: 11969677
    Abstract: A method for eliminating bubbles from a liquid dispensing system includes flowing a liquid containing bubbles into a liquid inlet of a tank from a filter to substantially fill the tank, wherein substantially all bubbles accumulate in an upper portion of the tank having a lateral dimension greater than a lateral dimension of a lower portion of the tank, and flowing the liquid into the tank comprises flowing the liquid through an inlet pipe extending at an acute angle relative to a horizontally-oriented axis of the tank. The method further includes flowing a liquid substantially free of bubbles out of the tank via a liquid outlet at the lower portion of the tank for dispensing to a substrate.

  • Patent number: 11087443
    Abstract: An augmented reality system and a color compensation method thereof are proposed. The method is applicable to an augmented reality system having a display and an image sensor and include the following steps. A preset object position of a virtual object with respect to an actual scene is set. An image of the actual scene is captured by using the image sensor, and the image of the actual scene is mapped to a field of view of the display to generate a background image with respect to the field of view of the display. Color compensation is performed on the virtual object according to a background overlapping region corresponding to the preset object position in the background image to generate an adjusted virtual object, and the adjusted virtual object is displayed on the display according to the preset object position.
