Patent number: 11876593Abstract: A system of a machine includes a network of nodes distributed throughout the machine. Each of the nodes is operable to communicate using a plurality of electromagnetic signals. A controller is operable to communicate with the nodes using electromagnetic signals. A radio frequency-based repeater is in the network between the controller and at least one of the nodes. The radio frequency-based repeater is configured to operate using power extracted from at least one of the electromagnetic signals when a signal-to-noise ratio is above a threshold, and the radio frequency-based repeater is configured to use energy stored in an onboard energy storage system when the signal-to-noise ratio is below the threshold.Type: GrantFiled: October 7, 2022Date of Patent: January 16, 2024Assignee: RTX CORPORATIONInventors: Jonathan Gilson, Joseph V. Mantese, Goran Djuknic, Gurkan Gok, Brenda J. Lisitano, Sanjay Bajekal, Coy Bruce Wood
