  • Publication number: 20100115145
    Abstract: A plug-and-play device comprises a first plug-and-play interface for establishing a connection with a first computing device and a second plug-and-play interface for establishing a connection with a second computing device. Storage stores code that is automatically executed by the second computing device when the plug-and-play device is connected to the second computing device via the second plug-and-play interface. The code when executed by the second computing device initiates a screen display data exchange between the first and second computing devices through the plug-and-play device. A controller controls the first plug-and-play interface, the second plug-and-play interface and the storage.

  • Patent number: 7076130
    Abstract: In order to reduce the possibility of a laser operating in multiple transverse modes at high power, the laser is provided with laterally asymmetric losses that discriminate against modes higher than the fundamental mode. One approach to doing this is form an asymmetric ridge waveguide in the laser, that allows the light of the higher order modes to leak out of the waveguide.

  • Patent number: 6806998
    Abstract: An optical communications control station includes an equipment rack and a fiber frame for interfacing between the fiber communications link and the equipment in the rack. Raman pump lasers in the equipment rack produce a Raman pump output that bypasses the fiber frame and is coupled directly into the fiber communications link. The number of connectorized components that the pump light passes through is reduced, thus reducing the possibility of damaging fiber connections by passing the high power Raman pump light through fiber connections. The approach also reduces the possibility of an operator being inadvertently exposed to the high power Raman pump light, thus increasing operator safety.
