Abstract: The present disclosure is a vent that has a grate comprising a plurality of louvers and a base. The grate is coupled to the base on an exposed face. The vent further has at least one fan coupled to the base on an opposing face that is adapted for moving air delivered to the grate through the louvers.

Abstract: An email messaging program with built in video and/or audio media recording and/or playback capabilities is disclosed. A system includes first and second clients, each having an email messaging program installed thereon. The user of the first client composes a message and records media. In a streaming media embodiment, the first client's messaging program uploads the media to a streaming media server, and sends the message to the user of the second client. In a file attachment embodiment, the messaging program attaches the recorded media to the message, and sends the message to the user of the second client. The second client's messaging program retrieves the message. In the streaming media embodiment, when the user of the second client views the message, the messaging program downloads the media from the streaming media server, and plays back the media. In the file attachment embodiment, the messaging program plays back the media.

Abstract: An application program and an audio or video program may run on an operating system. The audio or video program is integrated with the application program. A user of the application program interacts with the audio or video program as though the audio or video program were part of the application program.

Abstract: A system (10) for controlling the quality of the cabin air in an aircraft of the type having a cabin air recirculating system (37, 43) which introduces selectable amounts of fresh outside air, an arrangement (25, 27) for venting controllable quantities of cabin air to the atmosphere, and a source of oxygen-rich air (49). The system (10) includes sensors for monitoring the partial pressure of carbon dioxide (15) in the cabin air, the partial pressure of oxygen (17) in the cabin air, the humidity (19) of the cabin air, and the total air pressure (21) of the cabin air, and an air quality controller (23). The air quality controller (23) includes at least four inputs, one input connected to each of the sensors, and at least two outputs, one output connected in controlling relationship to the source (49) of oxygen-rich air and another (47) connected in controlling relationship to the cabin air recirculating system.
