Abstract:
Examples of devices, systems, and methods to manage aircraft water and waste servicing are disclosed. In one example, an aircraft water and waste controller has a network interface to receive water and waste data from water and waste devices in an aircraft. During a flight, the aircraft water and waste controller receives and stores the water and waste data. When the aircraft lands, the aircraft water and waste controller wirelessly transmits the water and waste data to one or more remote devices. The remote devices can use the water and waste data to determine water and waste ground services that need to be performed for the aircraft's upcoming flight(s).
Abstract:
The invention is a wireless sensor and telemetry system for use on a vehicle such as an aircraft including at least one sensor node, a gateway, a user control system, data management and analytics means, wherein the sensor node is capable of sensing at least one type of operational performance or structural condition parameter data for the vehicle. Sensor node is attached to the vehicle in a specific location so that the data acquired gives information to the users of the system that relates to the operational performance or structural condition of the vehicle during operation. The sensor node wirelessly transmits the data it acquires to the gateway. The user control system enables person/s, to remotely operate and control the wireless sensor and telemetry system, by sending wireless operational control instructions to the system either via the gateway or directly to a particular sensor node or to a cluster of sensor nodes.

Abstract:
A system and apparatus for data recording and analyzing operational data and methods for making and using the same are disclosed. The apparatus can monitor and record data generated by a plurality of operational and extended sensors each positioned on a moving platform. The data recording and analysis system can analyze the sensor data during movement and, by performing a statistical analysis of the operational data, can advantageously adjust one or more selected performance capabilities of the platform. For example, the performance envelope of a platform can be increased or decreased according to the experience of an operator. The recorded data can be transmitted at any suitable time, including during and/or after travel. The apparatus provides redundant storage capability and the ability to store information on removable media to enable sharing of data. Thereby, the system, apparatus and method advantageously can optimize the operator's overall experience controlling a platform.
