  • Publication number: 20230076046
    Abstract: A low-profile and small-size valve to a shut off a flow of fluid in a pipeline includes a frame, a tube, a moving part, a lever, an elastic part, a latch, and a trigger. The tube is movable with the moving part. The lever is rotatable around an axis. The elastic part can push the lever to rotate after the trigger pushes the buckle away from the lever to unlatch the lever and allow rotation. During the rotation of the lever, the lever pulls on the moving part, and the moving part pulls on the tube together to disconnect the tube from the pipe. The valve improves the convenience and efficiency of shutting off a flow of fluid. A pipeline and an immersion cooling system is also disclosed.

  • Publication number: 20220385873
    Abstract: A multi-point measurement of a scene captured in an image frame may be used to process the image frame, such as by applying white balance corrections to the image frame. In some examples, the image frame may be segmented into portions that are illuminated by different illumination sources. Different portions of the image frame may be white balanced differently based on the color temperature of the illumination source for the corresponding portion. Infrared measurements of multiple points in the scene may be used to determine a characteristic of the illumination source of different portions of the scene. For example, a picture that includes indoor and outdoor portions may be illuminated by at least two illumination sources that produce different infrared measurements values. White balancing may be applied differently to these two portions to correct for color temperature of the different sources.
