  • Patent number: 10774852
    Abstract: A hydraulic system for a working machine includes a hydraulic actuator having a first fluid chamber and a second fluid chamber, an accumulator, an outputting fluid tube to output an operation fluid, and a switching valve to be switched between a first position and a second position. The first position allows the first fluid chamber and the second fluid chamber to be communicated with the outputting fluid tube and thereby allowing a floating operation. The second position allows the first fluid chamber and the accumulator to be communicated with each other, allows the second fluid chamber and the outputting fluid tube to be communicated with each other, and thereby allows an anti-vibration operation.

  • Patent number: 9665263
    Abstract: Methods, systems, and computer-readable media for providing snap navigation in a scrollable list are presented. Certain items of the content items in the scrollable list may represent natural or desirable breakpoints for scrolling through the list. As a list view scrolls through the scrollable list in response to user input, the list view may suspend scrolling when it reaches a breakpoint content item. In some embodiments, a computing device may determine that a given content item represents a breakpoint in the scrollable list based on a breakpoint rule. The breakpoint rule may be based on any suitable criteria for identifying the content item as a breakpoint for scrolling the list. For example, the breakpoint rule may be based on the content of the content item or a category of the content item.
