Abstract: Technologies are generally described for valve assemblies that include a valve body whose inner wall defines two ports and a controllable flow path that extends along the inner wall between the two ports of the valve body. Each port may be fitted with a corresponding gasket. A rotatable member disposed in the controllable flow path of the valve body may include a hemispherical-shaped body with a substantially flat disk-shaped surface portion, and a seal ridge formed about a perimeter of the substantially flat disk-shaped surface portion. During opening and closing operation, the seal ridge may be selectively engaged with either one of the gaskets reducing an initial contact surface, and thereby reducing friction between the rotatable member and the gaskets.

Abstract: Technologies are described for providing safe and clean air and to prevent interchange of fluids or particulates between people in social situations through two or more distinct airflows generated and/or directed by various structures. An air safety system may receive pre-sanitized air and push through a guidance structure to create a low-velocity, clean air safe zone that prevents exchange of fluids and particulates within the zone and a high speed air shield to prevent injection of fluids and particulates from outside into the safe zone. The system may accommodate one or more persons in an open space of over a table/desk. A modular air safety system may generate a similar safe zone and air shield horizontally in a smaller scale for one or more people.

Abstract: A portable respirator as described may include an inflatable bag and a respirator body. The inflatable bag may be arranged to provide air to a patient through a face mask or an endotracheal tube in response to compression/retraction actions applied to the inflatable bag. The respirator body may include a first cover portion and a second cover portion arranged to enclose moving components of the portable respirator and define a substantially circular opening for the inflatable bag to be fitted through, a motor, a pair of levers positioned on opposing sides of the substantially circular opening, and a cam mechanically coupled to the motor and arranged to move the pair of levers in response to a rotation action by the motor such that the pair of levers apply the compression/retraction actions to the inflatable bag fitted through the opening.
