Abstract: A method and system are provided for updating software configurations of line-replaceable unit (LRU) computers in a restricted architecture network such as an in-flight entertainment system (IFES). Operating in an efficient and parallel manner, each of the LRUs independently creates an individual configuration file that identifies current software components. Each of the LRUs transmits its respective configuration file to a configuration server either automatically upon startup or manually upon request. The configuration server updates a system configuration data file with the current configuration files received from the individual LRUs. In a downloading method, a download server sends a list of desired software components to the LRUs. Each of the LRUs independently and simultaneously transfer (download) the needed software from the download server. The LRU independently requests the download server to download the needed software components. The file transfers utilize standard protocols, such as FTP.

Abstract: A low-profile D-subshell connector system is provided with interlocking components that can be used where space limitations are required. The system comprises a connector plug that has a connector; a backshell that houses a portion of the connector and is affixed to the connector; and a latch that is affixed to the connector and backshell. The latch comprises an angled tab that is resiliently pivotally mounted to a front portion of the latch. The tab comprises a wide region, a narrow region, and a release protrusion extending perpendicular from a top surface of the tab. A catch assembly engages the tab of the latch, the catch comprising a front portion having a notch therein. A part of the catch front portion serves to engage the wide region of the tab, thereby forcing the tab to pivot when the connector is partially inserted; and the narrow region of the tab resides in the catch notch when the connector is fully inserted.

Abstract: A system and method utilizing Internet Protocol (IP) sequencing to identify components of a passenger flight information system (PFIS). More particularly, the present invention relates to a system and method which assigns an IP address to each line replaceable unit (LRU), such as a seat electronics box (SEB) or other seat components of a PFIS, so that the components can be readily identified by the PFIS when communication is to occur between the components and, for example, a head end unit of the PFIS. Once the IP sequencing process has been performed, the PFIS can be used to provide services to the passengers, such as audio and video entertainment. Such entertainment can be set in accordance with an auto-scripting process in which the flight crew can select the theme for the flight.

Abstract: A system and method for streaming numerous video on demand (VOD) streams over a network, such as a local area medium sized network on a vehicle such as an aircraft. The system and method that provides redundant and restricted paths for streaming numerous VOD streams while providing maximum bandwidth for traffic from multiple sources with minimal packet loss due to contention.

Abstract: A system and method for wirelessly transferring content to and from a vehicle, in particular, an aircraft. The content includes, for example, data, voice, video and multimedia, that can be wirelessly exchanged over a wireless communication link between an aircraft and a ground station while the aircraft is at or near a parking gate, or between aircraft. In an example, the system employs long distance metropolitan area technology, such as IEEE Standard 802.16 wireless technology, to increase transfer range. The parameter of the wireless communication link can be adjusted based on, for example, the location of the link. The content can further be provided between the vehicle and ground station based on priorities, such as the available link speed, importance of the information, and/or anticipated connection time between the vehicle and ground station.
