Abstract: A system of a machine includes a network of nodes distributed throughout the machine. Each of the nodes is operable to communicate through electromagnetic signals. The system also includes a radio frequency transceiver, a first antenna coupled to the radio frequency transceiver, a second antenna coupled to one or more sensor nodes, and a controller coupled to the radio frequency transceiver. The controller is configured to select at least one sensor node to interrogate, transmit one or more interrogation frequencies from the radio frequency transceiver through the first antenna to the second antenna, receive one or more sensor frequencies at the first antenna broadcast from the second antenna based on a frequency response of the at least one sensor node to the one or more interrogation frequencies, and determine one or more sensed values based on the sensor frequencies received at the radio frequency transceiver through the first antenna.

Abstract: 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.

Abstract: A multi-mode microwave waveguide blade sensing system includes a transceiver, a waveguide, and a probe sensor. The transceiver generates a microwave energy signal having a first waveguide mode and a different second waveguide mode. The waveguide includes a first end that receives the microwave energy signal. The probe sensor includes a proximate end that receives the microwave energy signal from the transceiver and a distal end including an aperture that outputs the microwave energy signal. The probe sensor directs the microwave energy signal at a first direction based on the first waveguide mode and a different second direction different based on the second waveguide mode. The probe sensor receives different levels of reflected microwave energy based at least in part on a location at which the at least one microwave energy signal is reflected from the machine.
