Oxygen breathing device with redundant signal transmission
First Claim
1. A method for installing an emergency oxygen supply arrangement in an aircraft, the method comprising:
- Installing a plurality of passenger oxygen breathing devices, each comprising a sender and a receiver, wherein a sender of a first passenger oxygen breathing device of the plurality of passenger oxygen breathing devices is configured to communicate with a receiver of a second passenger oxygen breathing device of the plurality of passenger oxygen breathing devices and a sender of the second passenger oxygen breathing device is configured to communicate with a receiver of the first passenger oxygen breathing device,Establishing a network among these plurality of passenger oxygen breathing devices by self configuring and maintaining wireless connectivity between said senders and receivers of the plurality of passenger oxygen breathing devices,Further including in said network at least one pressure sensor coupled to a pressure sensor sender to wirelessly transmit an emergency decompression signal to at least the receiver of the first passenger oxygen breathing device to activate oxygen supply within the first passenger oxygen breathing device.
