Abstract: Nasal cannula assemblies for providing respiratory therapy to patients are provided. A nasal cannula assembly can include a cannula, an optional manifold which may be removable, a gas supply tube, and a securement mechanism. Securement mechanisms can include headgear straps, cheek pads, or an adhesive nose strip. A nasal cannula assembly can also include a lanyard, lanyard clip, and/or lanyard connector to help support the weight of a main gas delivery conduit.

Abstract: A method and apparatus for subjecting subterranean, fluid-bearing formations to magnetic flux forces. Magnetically susceptible fluids and magnetically susceptible particles are extracted from a subterranean well having a shaft or tube extending from the surface into a fluid containing formation and with an elongated rod within the shaft or tube.

Abstract: An apparatus to extract electromagnetically susceptible fluids and electromagnetically susceptible particles from a subterranean well having a shaft or tube extending from the surface to a fluid-containing formation and a mechanism to deliver the fluids and particles to the surface from the fluid-containing formation. The apparatus includes at least one electromagnetical coil within the shaft or tube. A direct current is supplied to the electromagnetic coil to generate a electromagnetic field in the fluid-containing formation. The magnetically susceptible fluids and particles are attracted toward the shaft tube through use of the electromagnetic field.
