Abstract: A medical appliance for the treatment of one or more sleep disorders such as obstructive sleep apnea in a patient, the appliance comprising: a biasing member for inserting behind and exerting a force upon the patient's soft palate or tongue, wherein the biasing member is inserted in a reduced or minimized form and then expanded or firms once in place to exert the force. The appliance may be nasally inserted or be placed through the mouth. In a particular configuration, both the soft palate and tongue are biased to prevent obstruction of the flow of air in the nasopharyngeal airway.

Abstract: Systems and methods include a wing tool configured to be operable from work vessel(s), the wing tool including thrusters capable of fluidizing sediments from a first seabed location and moving it to a second seabed location, the second seabed location including a trench or differently shaped collection sump previously made by the wing tool and/or an extraction pump. The extraction pump operates from a second work vessel having sufficient capacity to pump fluidized sediments from the trench. Certain systems include a separation unit that separates sand from silts and clays and water from collected sediment. Systems and methods for reclamation of reservoirs, moving sand waves, for pre-trenching and/or recovering marine pipelines and cables, for removing cover from marine archaeological sites and for disposing of contaminated bottom materials in an environmentally acceptable manner.

Abstract: A method for binding hazardous ammonia in both liquid or gaseous states from organic waste streams using carbon dioxide at ambient temperature and under ambient pressure to reduce ammonia emissions from farming or industrial operations. The method entraps a quantity of ammonia in an ammonia solution by reacting the quantity of ammonia with a quantity of carbon dioxide within a primary reaction vessel to form an ammonia-bound solution at ambient temperature and under ambient pressure. The ammonia-bound solution is able to be stored or transported for use in future chemical processes.

Abstract: A subjective refraction apparatus provides a variable optical correction along an optical axis. The subjective refraction apparatus includes a pair of lenses mounted on a mount in such a manner that the lenses are movable with respect to each other in a direction perpendicular to the optical axis for generating a variable spherical power along the optical axis. The mount is provided with a support defining a space for removably receiving an additional lens on the optical axis.
