Abstract: A radio frequency waveguide communication system includes a controller configured to output a radio frequency signal, and at least one connected node configured to output a node signal indicative of monitored parameter of a machine. The radio frequency waveguide communication system includes a waveguide and a radio frequency interface module. The waveguide is in signal communication with the controller and is configured to guide the radio frequency signal toward the at least one connected node. The radio frequency interface module is configured to establish signal communication between the controller and the at least one connected node, and includes at least one detachable portion configured to detach from the at least one waveguide.

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 a plurality of nodes distributed throughout the machine. Each of the nodes is operable to communicate through one or more radio frequencies, where the machine includes a cooler portion and a hotter portion. The system includes a means for communicating with the network of nodes using a higher frequency to communicate with one or more of the nodes in the cooler portion of the machine and a lower frequency to communicate with one or more of the nodes in the hotter portion of the machine.

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.

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. The system also includes a plurality of waveguides configured to guide transmission of the electromagnetic signals between the controller and one or more of the nodes. A radio frequency-based repeater is coupled to at least two of the waveguides 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.
