Abstract: A method for locating performance problems in a network comprising associating one or more metadata to a plurality of monitored objects, collecting performance data from the plurality monitored objects to create a correlation of the performance data across two or more monitored objects matching predetermined set of metadata. Displaying said correlation on a map representing a plurality of devices, wherein said correlation can be used to isolate one or more devices impacting said performance data.

Abstract: Systems and methods include receiving Operations, Administration, Maintenance, and Provisioning (OAM&P) data from an optical network; providing a Graphical User Interface (GUI) based on the OAM&P data with the GUI including a topology view; and providing a visualization that includes one of a power readings graph, a spectral analysis graph, and a spectral allocation graph, in the GUI, and the visualization is positioned logically next to the topology view.

Abstract: A golf club head is provided. The golf club head includes a face plate and a body. The face plate has an annular fastening portion with at least one fastening groove mounted therearound. The body has a clamping portion including at least one annular block and at least one annular stopper, so as to form an accommodation slot for accommodating the annular fastening portion. At least one flange is disposed on the top of the clamping portion. When the accommodation slot corresponds to the annular fastening portion, the face plate is squeezed towards the body, and the flange bears against the face plate and is squeezed and deformed to form a catching portion for engaging into the fastening groove, so that the face plate and the body are combined into a club head.

Abstract: A tunable vibration absorption device is provided that is suitable for active or semi-active vibration absorption or damping of vibrations in vibrating structures. It comprises a stack including a force actuator mechanism for generating an axial actuation force and a force sensor mechanism which is responsive to an external force acting on the stack to generate a force signal. A controller unit is electrically connected to the force sensor mechanism for receiving the force signal generated by the force sensor mechanism, and it is also electrically connected to the force actuator mechanism for adjusting the axial actuation force generated by the force actuator mechanism in response to the received force signal generated by the force sensor mechanism.

Abstract: A piezoelectric device is provided that comprises a mechanical amplifier adapted to produce a displacement output and/or receive a force input, and first and second flexible platforms connected to the mechanical amplifier. The first flexible platform is connected to one side of the mechanical amplifier and piezoelectric material is mounted on the first flexible platform for controllably flexing the first flexible platform. The second flexible platform is connected to another side of the mechanical amplifier and piezoelectric material is mounted to the second flexible platform for controllably flexing the second flexible platform.
