  • Apparatus and method for projecting identifying information onto seats
    Patent number: 6964481
    Abstract: A system and method for identifying seats within a mobile platform such as an aircraft, bus, ship, train, etc. A sensor subsystem detects when a door of the mobile platform is opened and transmits a wireless signal to each one of a plurality of projector subsystems. Each of the projector subsystems are disposed adjacent an associated seat of the mobile platform. Each projector subsystem projects an enlarged, optical signal with seat identifying information onto the seatback of its associated seat.
