Abstract: An airway visualization system is described herein having an elongate delivery sheath and defining at least one lumen therethrough, wherein the length is positionable within an airway of a subject. An isolation component positioned near or at a distal end of the elongate delivery sheath is expandable to at least partially obstruct the airway and a controller is in communication with the delivery sheath. The controller is also configured to manipulate a fluid flow through the at least one lumen whereby a pressure change within the airway of the subject is imparted sufficiently to at least partially expand or collapse the airway to alter the density of the airway.

Abstract: Methods and systems for augmentative and alternative communication are disclosed. An example method can comprise receiving a candidate input, classifying the candidate input as an intentional input, and generating a signal in response to the intentional input.

Abstract: A yagi antenna having a director element, a half-wave active dipole element, and a reflector element mounted on an antenna boom. All antenna elements are rods that are telescopically adjustable in length from a collapsible position to an operating length for a predetermined frequency of operation, and removable from threaded mounting for storage. The director element and reflector element are slidably adjustable on the antenna boom for independent spacing with respect to the half-wave active dipole element. The antenna boom has two mast support holes; one for horizontal polarization and the other for vertical polarization. A ferrite core member surrounds a coaxial cable connecting the half-wave active dipole element to a coaxial connector, and provides balun action between the coaxial cable and a balanced antenna feed point.
