  • Patent number: 8848339
    Abstract: A capacitor and a manufacturing method thereof are provided. Two electrodes are disposed opposite to each other. Two electrode protection layers are respectively disposed on inner sides of the electrodes and include carbon particles each covered and bonded with a polymer shell. Active carbon layers are disposed on opposite inner sides of the electrode protection layers. The separator is disposed between the active carbon layers. The electrolyte fills between the electrode protection layers. The polymer shells of each electrode protection layer are bonded to the surface of the corresponding electrode by first and second functional groups. The first functional groups include thiol groups. The second functional groups include epoxy groups or carboxylic groups. The electrode protection layers serve as adhesion layers between the active carbon layers and the electrodes, and protect the electrodes from being corroded by the acid electrolyte solution.

  • Patent number: 8850324
    Abstract: A system and technique for visualizing changes and trends in performance data over a network path are disclosed. More specifically, a network management system generates and displays an object that represents data for one or more performance characteristics related to a plurality of network nodes in the network path. The object is dynamically updated to include updated data related to the one or more performance characteristics. In one embodiment, a representation of the updated data is superimposed over representations of previously collected data relating to the performance characteristics. The transparency of the representations associated with the previously collected data may reflect a difference in time between the current time and the time at which the data was collected. In another embodiment, a timeline is included in the object that tracks the state of the object at one or more previous points in time.

  • Publication number: 20140284923
    Abstract: A pipe coupling has a lashing ring, a fastening screw and a gap shield. The lashing ring is mounted around a junction where two pipes are telescoped together. The fastening screw fastens two ends of the lashing ring. The gap shield is mounted on an inner surface of the lashing ring and covers a gap defined between the two ends of the lashing ring. With the gap shield covering the gap, when a fluid with high pressure flows through the pipes, the pipes do not deform at a part corresponding to the gap. Consequently, the fluid does not leak from the gap.
