Abstract: A remote pulse TDR liquid level measurement system and method may include inserting a probe into a body of water. The probe has a probe/air interface, and the body of water includes an air/water interface. A narrow pulse is remotely transmitted to the probe via a coaxial cable. A first impedance mismatch is received from the probe/air interface in a form of a positive reflected pulse, and a second impedance mismatch is received from the air/water interface in a form of a negative reflected pulse. A time between the positive reflected pulse and the negative reflected pulse is calculated, and the time is converted to a distance, the distance being indicative of the water level.

Abstract: Systems and methods for managing aircraft messages are provided. In one embodiment, the method can include receiving a message from an onboard system of an aircraft. The method can include determining a priority associated with the message based, at least in part, on data associated with the message. The data can be indicative of at least a content of the message. The method can include determining data indicative of availability for each of a plurality of communications networks based, at least in part, on one or more first parameters associated with the aircraft. The method can include selecting a network based, at least in part, on message priority, the data indicative of availability, and one or more second parameters associated with each of the networks. The method can include sending the message via the selected network when the network is available, or storing the message when the network is unavailable.

Abstract: Systems and methods for communicating a signal over a hydraulic line in a vehicle are provided. In one embodiment, a system can include a hydraulic line. The hydraulic line can include at least one communication medium for propagating a communication signal. The system can also include at least one signal communication device configured to receive the communication signal communicated over the hydraulic line. The system can also include at least one vehicle component in communication with the at least one signal communication device.
