Abstract: A pattern displaying device includes a light path changing element, a first light source, a second light source, and a control module. The light path changing element has first inclined surfaces to reflect light and arranged into a first predetermined pattern, and second inclined surfaces to reflect light and arranged into a second predetermined pattern. The first light source is operable to emit light toward the first inclined surfaces to display the first predetermined pattern. The second light source is operable to emit light toward the second inclined surfaces in order to display the second predetermined pattern. The control module is electrically connected to the first and second light sources to control the first and second light source to emit light or not.

Abstract: A process system for constructing network structure deployment diagram and the method thereof and a computer program product storing a network structure deployment analysis program are provided to analyze the network structure deployment of a target network. At first, a request instruction is sent by the process system for constructing the network structure deployment diagram to acquire network flow status messages. Interconnection relationship between the connection ports is analyzed by matching the acquired network flow status messages of the connection ports to generate the network structure deployment diagram of the target network. Accordingly, the invention utilizes the flow data messages of the connection ports in the network to create the network structure deployment diagram with advantages of easy implementation and high operation efficiency etc., and is especially suitable for large network systems with a large amount of network terminals.

Abstract: A drink can includes a can body with a resilient portion, a cap located on a bottle mouth of the can body and a separated holding portion coupled with the cap. The resilient portion is coupled with one set of pressure guards. The separated holding portion connected to the cap holds concentrate of a brewing stuff with a taste different from that held in the can body. The resilient portion formed on the belly of the can body can be squeezed to make a conical portion at the bottom of the can body to dislocate and open a sealing plate at the distal end of the separated holding portion, so that the concentrate of the brewing stuff can quickly drop into the can body to be diluted by the brewing liquid held in the can body to quickly mix the brewing liquid and brewing stuff.
