  • VACUUM DEVICE AND MULTISTAGE PRESSURE-SWITCHING DEVICE THEREOF
    Publication number: 20180093365
    Abstract: A vacuum device includes a negative pressure pump and a vacuum-switching device. The vacuum-switching device includes a cylinder, a piston and a piston-driving device. The cylinder has a first hole row, which includes a plurality of first vacuum suction holes. The cylinder has two through holes at two opposite ends, wherein either one of the two through holes is connected with a negative pressure pump. The piston is slidably connected within a hollow chamber inside the cylinder. The piston-driving device enables the piston to be slid back and forth so as to define two different-pressured chambers, thereby switching the first vacuum suction holes progressively to a different pressure.

  • SERVER LINK STATE DETECTION AND NOTIFICATION
    Publication number: 20160359982
    Abstract: Embodiments generally relate to link state change detection and notification within a server with embedded or directly integrated network switch. In a server configuration in which there is no longer a distinct separation between a network switch and a network interface card (NIC), the server can no longer immediately detect a change in the link state of any of the switch's ports. This can lead to connection failure. A Link State Policy Table is thus implemented within the embedded or integrated switch, capable of changing the NIC link state according to one or more pre-defined or user-defined policy settings. The server is then notified of the change in the NIC link state, and can release an old IP address or request a new IP address accordingly.
