Abstract: An aircraft in-flight entertainment (IFE) system includes an entertainment source, passenger seatback displays coupled to the entertainment source, and passenger control units. Each PCU is associated with a respective seatback display and includes a touchpad configured to recognize multiple simultaneous touch points.

Abstract: An aircraft in-flight entertainment (IFE) system includes an entertainment source, passenger seatback displays coupled to the entertainment source, and passenger control units (PCUs). Each PCU is associated with a respective seatback display. Each PCU includes an underside PCU input device carried by an underside of a seatback tray to be accessible by a user from the underside of the seatback tray when the seatback tray is in a stored position, and a topside PCU input device carried by a topside of the seatback tray to be accessible by the user from a topside of the seatback tray when the seatback tray is in a down position.

Abstract: An aircraft in-flight entertainment (IFE) system includes a headend unit, and a plurality of seat electronic boxes (SEBs) spaced throughout the aircraft. The headend unit includes a digital satellite radio receiver. A local area network (LAN) connects the digital satellite radio receiver for providing digital satellite radio signals to the SEBs. The IFE system further includes a plurality of passenger control units (PCUs) connected to the plurality of SEBs, with each PCU permitting passenger selection of the digital satellite radio signals.

Abstract: An aircraft in-flight entertainment (IFE) system includes an antenna for receiving digital satellite radio signals, and an intermediate frequency (IF) down converter is connected to the antenna for down converting the digital satellite radio signals. A plurality of seat electronic boxes (SEBs) are spaced throughout the aircraft. Each SEB includes at least one IF tuner in communications with the IF down converter.

Abstract: An aircraft in-flight entertainment (IFE) system includes a plurality of seat electronic boxes (SEBs) spaced throughout the aircraft. Each SEB comprises a memory including a shared memory portion for storing entertainment related data and an unshared memory portion. The SEBs cooperate with one another so that the entertainment related data in the shared memory portion of each SEB is available for at least one other SEB.

Abstract: An area entertainment system includes a headend unit, and electronic boxes spaced throughout the area. The headend unit includes a digital satellite radio receiver. A local area network (LAN) connects the digital satellite radio receiver for providing digital satellite radio signals to the electronic boxes. The entertainment system further includes user control units connected to the electronic boxes, with each user control unit permitting user selection of the digital satellite radio signals.

Abstract: A system and method for preventing collisions between vehicles, such as railway vehicles, by exchanging data regarding track position of the vehicles. By use of an on-board track database, the system provides an indication of the distance between vehicles based not on line-of-sight but on track distance. Additionally, a system and method for accurately determining location of railway vehicles without the use of a network of trackside indicators. The disclosed system uses a gyro, position indicator, and a satellite position determination along with a track database to maintain highly accurate estimates of measurement errors and track position.
