Abstract: A method for controlling a PCBA data distributed ledger located on blockchain network and a system for implementing the method are disclosed. The method may comprise scanning, by an optical label reader, an optical label located on a PCB and decoding, by an entity device, the optical label. The method may further include receiving, by a ledger controller, a request to access a distributed ledger from the entity device; verifying, by the blockchain nodes, a public key received from the entity device; determining, by the ledger controller, whether a private key received from the entity device matches a stored login credential; and determining whether to allow the entity device to access at least a first block on the distributed ledger.

Abstract: A wireless lighting system for an aircraft evacuation system. The wireless lighting system includes a wireless controller disposed in the aircraft having at least a transmitter configured to communicate an activation under an aircraft evacuation event when the aircraft evacuation system is deployed, and a first light source disposed on the aircraft evacuation system, the first light source configured to provide illumination to the aircraft evacuation system. The wireless lighting system also includes a first energy storage device disposed on the aircraft evacuation system and a first wireless receiver disposed on the aircraft evacuation system and configured to receive the activation signal from the wireless controller. The first wireless receiver is operably connected to the first energy storage device and the first light source and configured to activate the first light source based on the activation signal.
