Abstract: An aircraft reading light with a color-tunable reading light output includes: a white light source for emitting white light; a colored light source for emitting colored light; and an optical element, which is arranged for directing colored light that is emitted by the colored light source onto the white light source for being diffusely reflected at the white light source. The colored light source is controllable independently from the white light source.

Abstract: A respiration system includes a pressure regulator including a housing, an inlet for connection to a pressurized gas comprising oxygen, and a first data communication system, and a respiration facepiece including an interface to which the pressure regulator is removably attachable, at least one seal system to form a sealing engagement with the face of a user to encompass the nose and mouth of a wearer; an inspiration port in fluid connection with the pressure regulator interface and in fluid connection with the interior of the facepiece and at least one display within a volume of sealing engagement with the face of the user that is within the field of view of the user. The pressure regulator interface includes a second data communication system to receive data from the first data communication system to control the at least one display. A sealing attachment may, for example, be formed between the pressure regulator and the interface of the facepiece.

Abstract: A respiration system includes a regulator including an inlet for connection to a source of pressurized gas and an outlet for delivery of the gas to the user, and a respiration facepiece for use in connection with the regulator including an interface removably attachable to the regulator, at least one seal system adapted to form a sealing engagement with the face of a user, an inhalation port in fluid connection with the regulator interface and with the facepiece interior, an inhalation check valve in fluid connection between the inhalation port and the facepiece interior; an exhalation port in fluid connection with the facepiece; an exhalation check valve in fluid connection with the exhalation port; and an ambient port separate from the inhalation port and from the exhalation port, which is in fluid connection with the facepiece interior without an intervening check valve.

Abstract: In one aspect, a respiration system includes a regulator including an inlet for connection to a source of pressurized gas (which includes oxygen) and an outlet for delivery of the gas to the user, and a respiration facepiece for use in connection with the regulator.

Abstract: An apparatus for supporting a compressed-air bottle. The apparatus has a bottle support, a plurality of glide inserts projecting away from the bottle support and engageable with a compressed-air bottle supported on the apparatus, and a tightening strap for exerting a force on a compressed-air bottle supported by the apparatus. The tightening strap draws a compressed-air bottle against the glide inserts so that the glide inserts are repositioned relative to the bottle support.

Abstract: The invention relates to a bottle support (4) for compressed-air bottles (1), which is preferably used for the application of frames (5) and that is interposed between the compressed-air bottle(s) (1) and the frame (5). The inventive bottle support comprises glide inserts (3) that project from the surface of the bottle support (4) in the direction of the compressed-air bottles (1) so that every filled compressed-air bottle (1), when not braced, is received by the frame and can be glidingly moved. Under the action of force of a tightening strap (2) between the compressed-air bottle (1) and the frame (5) and thus a simultaneous action of force on the glide inserts (3), the glide inserts are sunk in the bottle support (4). The glide inserts (3) are configured as pins, knobs, buttons or ribs, at least two of the inserts acting on the periphery of one compressed-air bottle (1). They preferably consist of a synthetic material and are vulcanized, glued or buttoned into the bottle support (4).
