Abstract: A system is described that includes a controllable component of an engine configured to regulate fuel flow to the engine, a digital control unit configured to control the engine by at least communicating with the controllable component of the engine, and a protection component configured to disable communication between the digital control unit and the controllable component of the engine. The system further includes an analog control unit configured to control the engine by at least communicating with the controllable component of the engine in response to the protection component disabling communication between the digital control unit and the controllable component of the engine.

Abstract: Sensor assemblies and methods of de-icing or preventing ice formation are provided. Compressed air may be supplied to a vortex tube. The vortex tube may separate the compressed air into a first stream and a second stream, the first stream hotter than the second stream. A sensor body may be warmed by the first stream, and the second stream may be directed away from the sensor body.

Abstract: A system for fiber optic communication connections may include a connector housing, a circuit board disposed in the connector housing, and a port formed in the connector housing and sized to restrict ingress of a fiber optic cable into the port to a predetermined rotational orientation of the fiber optic cable. The system may include circuitry positioned for electrical communication with printed circuitry included on the fiber optic cable received in the port. The circuitry may receive and process data received as a light signal via the fiber optic cable. The system may further include an output connector extending from the connector housing and configured for detachable connection. The output connector may be in electrical communication with the circuitry and may be configured to receive and output an output electrical signal.
