  • Patent number: 7577963
    Abstract: An event translator system for receiving input information, parsing event data on the input information to produce a result event data set and generating an event list based on an analysis of the event the result data set, performing an event listing and displaying event list to a user interface module. The event translation system translating event data also include receiving user feedback on the event listing and using the user feedback to improve subsequent operations of at least one harvesting algorithm. Translating event data also includes at least two harvesting algorithms for performing the input information to generate a plurality of result event data sets and creating an event listing for display to a user interface module based on an analysis of the plurality of result event data sets.

  • Patent number: 7471859
    Abstract: An optical waveguide has a surface. An array of separately actuated bodies is disposed proximal to the exposed surface, and an actuator separately actuates at least some of the bodies to change a spectral characteristic of a wave propagating through the waveguide. Preferably, the bodies are metal striplines, an electro-optical material is disposed between the striplines and the exposed surface, and the actuator is a CMOS chip that imposes a voltage to some or all of the lines. The voltage changes the refractive index at the interface with the surface, changing an index of refraction profile of the waveguide and effectively imposing a grating. Alternatively, the bodies are micro-beams and the actuator, also controlled by a CMOS chip, separately moves each micro-beam into and out of proximity to the surface. The grating is programmable via the CMOS chip.

  • Patent number: 6496305
    Abstract: An optical amplifier for a 4-fiber system having two inputs and outputs is provided that makes use of a single amplifier rather than two separate amplifiers. The optical amplifier node makes use of an interleaver before and after the single amplifier to demultiplex and multiplex even and odd channel signals traveling in opposite directions. The arrangement can also amplify wide channel spaced signals traveling through a plurality of optical fibers. The optical amplifier node can be combined with other like amplifier nodes to provide more complex amplifier solutions at reduced costs due to the need for only half of the typical number of amplifiers. The optical amplifier node can also be combined with, e.g., variable optical attenuators, L/C/S filters, channel add/drop, co- and counter-propagating Raman amplification, and dispersion compensation modules to modify the optical signals as desired.
