  • Rotary closed-valve vacuum suction device
    Patent number: 11346389
    Abstract: A rotary closed-valve vacuum suction device is mounted to a bottom of an object, and has a valve assembly, a sucker, and a valve part. The valve assembly has a top valve seat and a bottom valve seat mounted below the top valve seat. The sucker is mounted to a bottom of the valve assembly. The valve part is inserted through a valve hole of the sucker and the bottom valve seat, and is connected to the top valve seat. When one of the top valve seat and the bottom valve seat is rotated to change the relative position between the bottom valve seat and the top valve seat in a height direction of the valve assembly, the valve part switches the valve hole of the sucker between an open state and a closed state.

  • Keystroke determination method and device thereof
    Patent number: 9239629
    Abstract: A keystroke determination method and a device thereof are applicable to a keyboard input device. The keystroke determination device performs the keystroke determination method including the following steps. A triggering signal corresponding to both a first circuit node and a second circuit node of the keyboard input device is received. Whether a first key definition of the first circuit node represents a null key is determined. When the first key definition of the first circuit node represents the null key, a signal specifying a second key definition of the second circuit node is outputted.
