Abstract: A network and method for addressing the network includes a host controller, a communication bus connected to the host controller, and a plurality of nodes connected to the communication bus. Each of the plurality of nodes includes a node controller, a communication input, and a communication output. The node controller is configured to receive an address from the host controller, provide an acknowledgement of receipt of the address to the host controller, and connect the communication input to the communication output upon receipt of the address.

Each of the plurality of nodes includes a node controller, a timer, a communication input connected to the communication bus and a communication output connected to the communication bus. The node controller is configured to connect the communication input to the communication output upon successful receipt of an address from the host computer or upon the timer reaching a threshold.

Abstract: A system for an aircraft includes a first fluid circuit extending from a first end to a second end, and a network comprising a plurality of networked heater assemblies disposed along the first fluid circuit between the first end and the second end. Each of the networked heater assemblies includes at least one temperature sensor, a heater element, and a local controller. The at least one temperature sensor is in communication with the first fluid circuit for periodically measuring a temperature in the first fluid circuit and generating a corresponding local temperature signal. The heater assembly selectively applies heat to the first fluid circuit based on the local temperature signal or another temperature signal on the network. The local controller receives the local temperature signal or another networked temperature signal and operates the heater assembly in response thereto to maintain the local temperature signal above a predetermined threshold.

Abstract: A computer implemented method includes transmitting a transmit command to a first data concentrator to send out a predetermined signal of predetermined characteristics according to a transmission setting, receiving a received signal from at least one second data concentrator, and determining if there are any signal transmission effects between the first data concentrator and the second data concentrator based on a comparison of the predetermined signal and the received signal.

Abstract: A wireless system and method includes an initiator and a responder. The initiator includes a first transceiver and is configured to generate a new encryption key. The responder includes a second transceiver and is configured to communicate wirelessly with the initiator via the second transceiver. The initiator is further configured to measure a radio-frequency interference at the first transceiver and determine an iteration number based upon the radio-frequency interference, and transmit a key update message encrypted with a current encryption key that includes the new encryption key to the wireless responder. The initiator is also configured to resend the key update message the iteration number of times if the initiator did not receive an acknowledgement from the responder.
