Apparatus and method for projecting identifying information onto seats
First Claim
1. A system for projecting information content onto a seat located within a predefined area of a structure, when a door of the structure is opened to aid an individual in locating a specific one of said seats while said door is opened, the system comprising:
- a sensor system located adjacent said door for detecting when said door is opened;
a projector subsystem located in front of said seat for projecting said information content onto said seat, said projector subsystem including;
a projector for projecting an optical signal onto said seat, said optical signal containing said information content; and
a controller for controlling said projector in accordance with said signal from said sensor.

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.

8. An apparatus for projecting information onto a surface when a desired condition is present in an environment in which said apparatus is located, the apparatus comprising:
-
a receiver for receiving an electromagnetic signal generated when said desired condition is present; a projection system for projecting an optical signal onto said surface to present said information in visually readable form to an individual; and a detection system to detect if an individual is present in a path of said optical signal; and wherein said projection system is responsive to a signal from said detection system to interrupt said optical signal when the presence of said individual in said path of said optical signal is detected, and also to retransmit said optical signal when said signal from said detection system abates. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A system for projecting information content onto a seat when a first condition occurs in a predefined area in which said seat is located, said system comprising:
-
a transmitter disposed adjacent a structural element associated with said predefined area, for generating a first signal indicating the occurrence of said first condition; a projection subsystem located adjacent said seat so as to be facing said seat, said projection subsystem comprising; a receiver for receiving said first signal; a controller for receiving said first signal; a projector for projecting an optical signal onto said seat, said optical signal providing said information content; a detection system for detecting if an individual is present in said seat and generating a second signal indicating same; and said controller controlling said projector and said detection system in accordance with receipt of said first signal, and further in accordance with said second signal so as to turn off said projector when said second signal is present. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A method of aiding an individual in locating a specific structure from a plurality of like structures in a predefined area, comprising:
-
disposing an projector system adjacent each one of said structures; configuring each said projector system to generate a unique identifying message in the form of an optical signal directed at its associated said structure, to thus project a unique, optical identifying message directly onto its associated said structure that is visually readable by an individual; using a plurality of sensors, each said sensor being independently associated with a specific one of said structures, to detect when an individual is positioned in front of a specific one of said structures; and turning off said projector system associated with said sensor that has detected the presence of said individual in front of said structure. - View Dependent Claims (26, 27, 28)

29. A method for identifying seats within a predetermined area, comprising:
-
using a plurality of projectors, with each said projector being disposed in front an associated one of said seats, to project an optical signal onto each said seat uniquely identifying each said seat; and turning off a given one of said projectors when an individual is seated in said given one of said seats.

30. A fold down seat tray comprising:
-
a projector system for projecting an optical signal onto a portion of an adjacently positioned seat; and an optical detection system operably associated with said projector subsystem for disabling said projector system when an individual has occupied said adjacently positioned seat.
