    摘要： A node of a radio frequency waveguide system can include a waveguide interface, a signal splitter, a power rectifier and conditioner, a communication filter, and a network processor. The waveguide interface is configured to communicate through a waveguide in the radio frequency waveguide system. The signal splitter is configured to split a radio frequency transmission received at the waveguide interface between a power path and a communications path within the node. The power rectifier and conditioner are configured to produce a conditioned power signal based on power received through the power path. The communication filter of the communications path is configured to produce a filtered communication signal. The network processor is powered by the conditioned power signal and configured to extract encoded information from the filtered communication signal.

    摘要： An engine system of an aircraft includes an energy storage system, a gas turbine engine, and a controller. The gas turbine engine includes a low spool, a high spool, a low-spool generator operably coupled to the low spool, and a high-spool electric motor operably coupled to the high spool. The controller is configured to detect a braking condition of the aircraft, transfer power from the low-spool generator to the energy storage system based on the storage capacity state of the energy storage system, and transfer power to the high spool through the high-spool electric motor to support combustion in the gas turbine engine while a rotational speed of the low spool is reduced responsive to the low-spool generator extracting energy from the low spool.

    摘要： A system of a machine includes a network of a plurality of nodes distributed throughout the machine, a controller, and a power extraction system within at least one of the nodes. Each of the nodes is operable to communicate through one or more radio frequencies. The controller is configured to communicate with the network of nodes by transmitting the one or more radio frequencies through one or more waveguides. The power extraction system is configured to extract power from the one or more radio frequencies as a first power source, extract power from a second power source, and provide power to one or more components of the system based on power extracted from either or both of the first power source and the second power source.
