Abstract: A Rydberg atom mixer determines a phase of modulated carrier radiation and includes: a reference radiofrequency source for reference radiofrequency radiation; a modulated carrier source for modulated carrier radiation; a vapor cell to contain gas atoms and that receives reference radiofrequency radiation and modulated carrier radiation, such that the gas atoms produce modulated light modulated; and a transmission detector that receives the modulated light from the vapor cell and produces a transmission signal from the transmission detector for determination of a phase of the modulated carrier radiation, wherein the Rydberg atom mixer mixes the reference radiofrequency radiation and the modulated carrier radiation by the gas atoms in a Rydberg electronic state to produce the intermediate frequency IF that corresponds directly to the phase of the modulated carrier radiation.

Abstract: Embodiments of the present invention relate to methods and apparatus for sorting undesired marine species during trawling, provides a pliable grid when the trawl net is pulled from the water and wound tightly on the net reel, and when the trawl is deployed in the water, the apparatus is fixed into place inside the trawl and holding its shape with consistent grid spacing. Marine species sorting apparatus in accordance with embodiments of the present invention includes grid, back straps, and lead ring. Grid includes a plurality of bars surrounded by grid frame. Grid frame is attached to lead ring at an angle using terminal couplers. Lead ring supports grid and secures marine species sorting apparatus in trawl webbing referred to as the extension.
