A gasper assembly for use in a passenger aircraft. The gasper assembly includes an inlet comprising a socket configured to receive intake air; and an outlet comprising a body mounted in the socket that is manually adjustable to direct a stream of airflow received via the inlet in a first direction and in a second direction. The body is further configured by a first rotation to direct the stream of airflow in the first direction and by a second rotation to direct the stream of airflow in the second direction wherein the first direction is substantially perpendicular to the second direction.

An air distribution coupling interface is configured to removably secure to a floor of an internal cabin of a vehicle. The air distribution coupling interface includes a main tube extending between an air inlet port and an air outlet port. The air inlet port is configured to couple to one or more conduits that are in fluid communication with an air distribution system. A securing flange is configured to removably secure the air distribution coupling interface to the floor of the internal cabin. The air outlet port is configured to deliver airflow provided by the air distribution system.

An aircraft including a fuselage having a side wall at least partially defining a passenger cabin and a crown section of the aircraft. The passenger cabin includes an overhead zone, a passenger zone, and a floor zone. An air supply duct is positioned within the crown section, and the air supply duct is configured to pressurize the crown section with air. At least one return air outlet is defined in the floor zone. An interior structure is coupled to the side wall and extends between the passenger cabin and the crown section. The interior structure includes a plurality of nozzles oriented to discharge the pressurized air from the crown section along an airflow path that extends downward through the overhead zone, downward through the passenger zone, and then towards the at least one return air outlet.

An aircraft is provided that includes a passenger service unit for a passenger seated in a seat in its cabin. The aircraft includes a camera configured to acquire an image of the passenger, and a control module configured to at least receive the image of the passenger. The control module is configured to receive non-tactile gesture preference data and dominant hand data, and access a non-tactile gesture data store that includes a plurality of images of non-tactile hand signals or non-tactile hand gestures. Based on the foregoing, the control module is configured to generate non-tactile gesture data in accordance with and indicative of a non-tactile hand signal or a non-tactile gesture made by the passenger. And the control module is configured to control one or more cabin systems including in at least one instance the passenger service unit based on the non-tactile gesture data.

A personal valve apparatus may include a nozzle, a valve seat, and a moveable poppet valve. The nozzle may comprise an inner air-flow surface having a nozzle cavity extending through the inner air-flow surface. The valve seat may comprise a seat member disposed at an end of the inner-air-flow surface with the seat member disposed over the nozzle cavity. The moveable poppet valve may be disposed over the seat member and the nozzle cavity. The moveable poppet valve may comprise a convex surface. When the moveable poppet valve is in an open position, the convex surface may be disposed over and apart from the seat member to allow air to flow from the nozzle cavity, against the convex surface, between the seat member and the convex surface, and beyond the seat member. The convex surface of the poppet valve may reduce air turbulence, drag, flow separation, and/or noise within the valve apparatus.

An apparatus for locational aiming of an overhead directional service unit includes a body including a first end configured to be matingly engaged with a housing assembly of the overhead directional service unit and a second end longitudinally opposed to the first end. A light source is disposed within the body and operable to project a light beam from the second end in a direction defined by a longitudinal axis of the body. With the first end matingly engaged with the housing assembly, pivotal movement of the body about a pivot axis relative to a mounting assembly of the overhead directional service unit applies a leverage force to the housing assembly to pivotally reposition the housing assembly relative to the mounting assembly so that the housing assembly is directionally aimed toward a target location visually indicated by the light beam.

A sanitizing assembly for sanitizing passenger seats of an airplane includes a power module, a pump, a tank, and plurality of dispensers. The power module, the pump, the tank, and the plurality of dispensers are coupled to and positioned in an airplane. The pump is operationally coupled to the power module. The tank is fluidically coupled to the pump. The tank is configured to store a sanitizer solution. The plurality of dispensers is fluidically coupled to the pump. Each dispenser is positioned proximate to a respective seat of the airplane. The pump is positioned to compel the sanitizer solution from the tank to the plurality of dispensers. The sanitizer solution is sprayed onto the seats to sanitize the seats.

A system for controlling passenger services includes a sensor that generates a signal representative of the at least one of the position of the seat, the presence of passenger in the seat, the position of the at least one hand of the passenger, the configuration of the at least one hand of the passenger and the direction of movement of the at least one hand of the passenger. A first light source, an air supply, and a window shade are disposed at a predetermined locations with respect to the seat. A controller, connected to the sensor, generates a control signal that controls at least one parameter associated with at least one of light generated by the first light source, air supplied by the air supply and a degree of openness of the window shade.

An aircraft is provided that includes a passenger service unit for a passenger seated in a seat in its cabin. The aircraft includes a camera configured to acquire an image of the passenger, and a control module configured to at least receive the image of the passenger. The control module is configured to receive non-tactile gesture preference data and dominant hand data, and access a non-tactile gesture data store that includes a plurality of images of non-tactile hand signals or non-tactile hand gestures. Based on the foregoing, the control module is configured to generate non-tactile gesture data in accordance with and indicative of a non-tactile hand signal or a non-tactile gesture made by the passenger. And the control module is configured to control one or more cabin systems including in at least one instance the passenger service unit based on the non-tactile gesture data.

An aircraft includes a plurality of seats and an input device coupled to each of the plurality of seats. The aircraft also includes a remotely controlled nozzle positioned proximate each seat of the plurality of seats. Each nozzle includes an actuator assembly including at least one actuator and an actuator shaft. The at least one actuator is configured to move the actuator shaft between an open position and a closed position to control an airflow through the nozzle in response to a signal received from a respective input device of the input devices, wherein the signal represents a position of the actuator shaft.
