Abstract: An aircraft includes a flight deck including a flight deck door configured to be moved between an open position and a closed position, a first monument, second monument, and a secondary barrier door moveably secured between the first monument and the second monument. The secondary barrier door is configured to fold into a stowed position in which a path to the flight deck is open, and unfold into a deployed position in which the path to the flight deck is closed.

Abstract: A barrier door system to control movement of persons through an opening within a cabin area of an aircraft. The barrier door system includes a track with an elongated shape with a first end and a second end. A barrier door includes panels that are pivotally connected together and one or more pins that extend outward from a top edge of the barrier door and are configured to engage with the track. The panels are configured to pivot together in a folded configuration at a stowed position, and to pivot outward away from the track in an extended configuration to extend across the opening at the deployed position.

Abstract: A barrier door system to control movement of persons through an opening in an interior space of an aircraft. The barrier door system having a frame with outer members that extend around a gap. A barrier door has a first panel and a second panel that are pivotally connected together with the barrier door pivotally connected to the frame. The barrier door is movable between a stowed position and a deployed position. The stowed position includes the first panel and the second panel folded together in an overlapping configuration and positioned in the gap in the frame and away from the opening. The deployed position includes the first panel and the second panel positioned away from the gap and extending across the opening.

Abstract: A barrier door system configured to be positioned at an opening within an interior of an aircraft. The barrier door system comprises a door that is movable between a stowed position away from the opening and a deployed position that extends across the opening. A lock is mounted to the door and configured to lock the door in the deployed position with the lock configured to be immediately movable from a locked position to an unlocked position from a forward side of the door and to delay moving from the locked position to the unlocked position from a rear side of the door.

Abstract: An apparatus, system, or method wirelessly sends an audio component of a multimedia channel to one or more wireless computing devices while a visual component of the multimedia channel is playing on a video monitor. The audio component may be packetized into data packets and broadcast via a network such that the data packets can be received and played by the wireless computing devices in synchronization with the visual component playing on the video monitor. A channel listing may inform the wireless computing devices what channels are available. A visual content that is not the visual component of the multimedia channel may be displayed on the wireless computing device while an audio component of the multimedia channel is streamed to the wireless computing device.

Abstract: An apparatus, system, or method may wirelessly send an audio component of a multimedia channel to one or more wireless computing devices while a visual component of the multimedia channel is playing on a video monitor. The extracted audio component of the multimedia content may be packetized into data packets and broadcast via a network such that the data packets can be received by the wireless computing devices and the audio component can be played by the wireless computing devices in synchronization with the visual component playing on the video monitor. A channel listing may inform the wireless computing devices what channels are available. A visual content that is not the visual component of the multimedia channel may be displayed on the wireless computing device while an audio component of the multimedia channel is streamed to the wireless computing device. A direction indicator may be displayed on the wireless computing device to indicate the direction of a video monitor playing the visual component.

Abstract: A device, system, and method may provide an audio component of a multimedia stream playing on a video monitor to one or more wireless computing devices. The extracted audio component of the multimedia content may be packetized into data packets and broadcast via a network such that the data packets can be received by the wireless computing devices and the audio component can be played by the wireless computing devices in synchronization with the visual component playing on the video monitor.

Abstract: A system and method for providing an audio component of a multimedia content playing on an electronic display device to one or more wireless computing devices utilizes a synchronization player application of the electronic display device to display a visual component of the multimedia content on a display of the electronic display device and to extract the audio component from the multimedia content. The extracted audio component of the multimedia content is packetized into data packets and broadcast into a network so that the data packets can be received by the wireless computing devices to play the audio component of the multimedia content in synchronization with the visual component of the multimedia content being displayed on the display of the electronic display device.
