OXYGEN BREATHING DEVICE WITH REDUNDANT SIGNAL TRANSMISSION
First Claim
1. An arrangement of a plurality of oxygen breathing devices, in particular for providing oxygen to passenger or crew of an aircraft, each oxygen breathing device comprising:
- an oxygen source, wherein oxygen is stored, in particular in chemically bound form or compressed form,an oxygen guiding device for guiding oxygen from the oxygen source to a person,wherein a first one of said plurality of oxygen breathing devices further comprises an integrated transmitter comprising;
a sender adapted for wireless communication with a receiver of a second one of said oxygen breathing devices anda receiver adapted for wireless communication with a sender of said second oxygen breathing device,wherein said second oxygen breathing device is arranged in a distance from the first oxygen breathing device,wherein the sender and receiver of said integrated transmitter are adapted to receive and send at least a decompression signal signalising the need to activate oxygen supply from said oxygen source via said oxygen guiding device, andwherein preferably said transmitter is connected to said oxygen source to activate oxygen supply via said oxygen guiding device upon receipt of such decompression signal.

Abstract
The invention relates to an arrangement of a plurality of oxygen breathing devices, in particular for providing oxygen to passenger or crew of an aircraft, each oxygen breathing device comprising an oxygen source, wherein oxygen is stored, in particular in chemically bound form or compressed form, an oxygen guiding device for guiding oxygen from the oxygen source to a person. According to the invention, an arrangement of a plurality of oxygen breathing devices is provided, wherein a first one of said plurality of oxygen breathing devices further comprises an integrated transmitter comprising a sender adapted for wireless communication with a receiver of a second one of said oxygen breathing devices and a receiver adapted for wireless communication with a sender of said second oxygen breathing device, wherein said second oxygen breathing device is arranged in a distance from the first oxygen breathing device, wherein the sender and receiver of said integrated transmitter are adapted to receive and send at least a decompression signal signalising the need to activate oxygen supply from said oxygen source via said oxygen guiding device, and wherein preferably said transmitter is connected to said oxygen source to activate oxygen supply via said oxygen guiding device upon receipt of such decompression signal.
