Abstract: This invention provides the design of a spin-controlled faucet outlet structure. It contains a valve seat inside a rotation set. The valve seat houses a turn button, a scaling plate and a discharging plate. These three pieces are locked together and controlled on the valve seat through a bridging seat. The bridging seat is locked to the faucet outlet. The turn button and the sealing plate along with the turn button and the rotation set move in series. The bottom of the rotation set is connected to a bubbler. The turn button of the rotation set spins with the sealing plate together and changes the blockage of the faucet outlet using the sealing plate, making it function as the controller of discharging and stopping water.

Abstract: The invention provides a system management apparatus for a multi-shelf modular computing system. The system management apparatus receives and parses an alert information in response to an abnormal parameter/state relative to a component of the multi-shelf modular computing system sent from a shelf management device of the multi-shelf modular computing system, and stores the parsed alert information into a storage module. Then, the system management apparatus periodically retrieves the parsed alert information, if any, from the storage module and generates a visual alert information indicating the abnormal parameter/state. Thereby, a user can view the visual alert information to perceive the abnormal parameter/state rapidly and intuitively, so as to take corresponding measures.
