    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 a plurality of electromagnetic signals. A controller is operable to communicate with the network of nodes through the 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 receive a portion of the electromagnetic signals in a first waveguide and boost a transmission characteristic of the portion of the electromagnetic signals in a second waveguide.

    Abstract: A heat transfer system is disclosed in which, an electrocaloric material includes a copolymer of a monomer mixture including (i) vinylidene fluoride, (ii) an addition polymerization monomer selected from tetrafluoroethylene, trifluoroethylene, or a monomer smaller than trifluoroethylene, and (iii) a halogenated addition polymerization monomer different than (ii) that is larger than vinylidene fluoride. The electrocaloric material also includes an additive selected from a nucleating agent having a polar surface charge, electrocalorically active solid particles, or a combination thereof. Electrodes are disposed on opposite surfaces of the electrocaloric material, and an electric power source is configured to provide voltage to the electrodes. The system also includes a first thermal flow path between the electrocaloric material and a heat sink, and a second thermal flow path between the electrocaloric material and a heat source.

    Abstract: An acoustic wave gate is provided. The gate includes one or more layers of metamaterial configured to be in a first state and a second state and configured to change from the first state to the second state when electrical and/or magnetic energy is applied thereto. The gate also includes at least one source configured in operational communication with the one or more layers and configured to supply at least one of electrical and magnetic energy to the one or more layers. The one or more layers are configured to (i) prevent the passage of acoustic energy through the one or more layers when in the first state and (ii) permit the passage of acoustic energy through the one or more layers when in the second state, wherein the one or more layers are configured to be stimulated in phase with the acoustic energy.
