  • Patent number: 11196496
    Abstract: A frequency-selective system that may be used as, or as part of, an add/drop multiplexer. An input signal is fed to a Mach-Zehnder interferometer configured to drop, or suppress, by destructive interference, a signal component in a first frequency band from among a plurality of frequency bands. One or more bandpass filters in one arm of the Mach-Zehnder interferometer suppress other frequencies, outside of the first frequency band, so that signals at these other frequencies are not suppressed by destructive interference and are present at the output of the Mach-Zehnder interferometer. A coupler connected after the output of the Mach-Zehnder interferometer adds, into the signal path, a replacement for the dropped signal.

  • Patent number: 8966816
    Abstract: The modular aquaponics assembly includes a frame, at least one tray adapted for retaining water and supporting at least one container for retaining a growing medium therein for support plants. A light fixture is disposed within the frame above the at least one tray, and an aquarium for supporting aquatic fauna is positioned near the bottom of the frame. A water circulating system is provided for circulating water from the aquarium through the at least one tray and back to the aquarium. In one embodiment, the frame is adapted to removably sit on top of the aquarium. In another embodiment, an outer skin encloses the frame, aquarium and other components to create an aesthetically pleasing structure that is both decorative and functional.

  • Publication number: 20050159128
    Abstract: An adaptive interference canceller for canceling an interfering signal corresponding to a delayed, frequency translated, amplitude and phase offset version of a transmitted signal contained in a composite received signal relayed through a relay system such as a satellite transponder. The canceller digitally downconverts the received signal and a local replica of the transmitted signal from IF to baseband, applies a variable delay and frequency compensation to the replica as a coarse delay and frequency correction, and tracks fine delay, amplitude and phase differences using an adaptive finite impulse response filter to generate a cancellation signal corresponding to the delayed and frequency shifted version. A minimum output power process produces an error signal that drives the variable delay and adaptive filter to minimize the power in the signal of interest to maximize cancellation of the interfering signal.
