Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
146 words
An electrical power transfer system for an aircraft Passenger entertainment system comprising in combination: an aircraft passenger seat track having a plurality of apertures distributed there along for insertion of passenger seat legs; said seat track having a rectangularly shaped cross section; a plurality of passenger seat entertainment system power connectors; a conductor rail assembly having a plurality of apertures distributed there along for receiving said plurality of passenger seat entertainment system power connectors, said conductor rail assembly having a rectangularly shaped cross section; a passenger entertainment system power supply; said conductor rail assembly having an enclosed conductive strip extending along the length thereof in electrically insulated relationship with respect to said seat track; said passenger entertainment system power supply coupled between said conductive strip and said seat track; and, said plurality of passenger seat entertainment system power connectors making electrical contact with said conductive strip.
Claim 2
Dependent Claim
