    摘要： Apparatus and associate methods relate to desaturation protection of a metal-oxide-semiconductor field-effect transistor (MOSFET) or an insulated-gate bipolar transistor (IGBT). Desaturation protection circuitry provides desaturation protection to the MOSFET or IGBT as well protection of the desaturation protection circuitry, should such circuitry be connected to reverse power. The desaturation protection circuitry determines a desaturation condition based on a control voltage generated by a Zener-diode-resistor network conductively coupled between first and second conduction nodes of the MOSFET or IGBT. The Zener-diode-resistor network is coupled to first and second conduction nodes via a rectifying diode that is configured to protect the desaturation protection circuitry from reverse bias power. Negative feedback limits current through a signal isolation device that is conductively isolated from the output node, which indicates whether the desaturation condition has been determined.

    摘要： A secure network interface system includes a secure domain interface, a processing system, a network function device, and a network interface. The processing system is configured to send and receive information within secure systems, transmit configuration data for the network interface, compile data from the secure systems into a plurality of data packets, and transmit the plurality of data packets to the network function device without being physically capable of receiving data packets from the network function device, thus providing a demonstration of security partitioning. The network function device receives the configuration data, configures the network interface using the configuration data, and provides discrete feedback to the processing system regarding a configuration status. The network interface sends the plurality of data packets to one or more external unsecure systems and to limits a communication protocol type received from one or more external unsecure systems.

    摘要： An optical sensor for an aircraft includes two detectors, a light source, and a controller. The detectors are oriented along detector paths and have tilt angles and fields of view. The detectors are configured to detect light reflected from an illumination volume and to generate detector signals that correspond to intensities of detected light. The tilt angles are equal such that each detector is oriented in an opposite direction within a plane containing a light source path and the detector paths. The light source is oriented along the light source path and is configured to illuminate the illumination volume which overlaps with the fields of view within a predetermined distance range. The controller is configured to receive the detector signals, detect whether a cloud is present based upon the detector signals, determine a cloud phase, and calculate a density of the detected cloud.

    摘要： A pressure sensor includes a header with a cavity, a pressure sensing element, an isolator, an isolator support, a damping gap, and oil. The pressure sensing element is in the cavity. The isolator has corrugations and is mounted to a top of the header. The isolator covers the cavity. The isolator support is in the cavity of the header above the pressure sensing element. The isolator support is corrugated. The corrugations of the isolator support align with the corrugations on the isolator. The damping gap is between the isolator support and the isolator. The damping gap has a constant width between the isolator support and the isolator. Oil fills the damping gap and the cavity in the header. The oil moves between the damping gap and the header cavity in response to external pressure changes moving the isolator.

    摘要： A method for collaboration of a plurality of nodes includes determining at each node SLAM data for the node, the SLAM data including estimated position of features and/or targets observed and processed by the node using SLAM algorithms and covariance associated with the estimated positions, communicating at each node the node's SLAM data to the other nodes via each nodes' datalink communication system, receiving at each node SLAM data communicated from the other nodes via each node's datalink communication system, combining at each node the node's SLAM data and the SLAM data received from the other nodes based on features or targets included in SLAM data from the other nodes, refining at each node estimated positions of features and/or targets based on results of the combining, and navigating each node to a target at the target destination as a function of at least one of the refined estimated positions.

    摘要： Apparatus and associated methods relate to predicting failure and/or estimating remaining useful life of an air-data-probe heater. Failure is predicted or useful life is estimated based on an electrical metric of the electrical operating power provided to a resistive heating element of the air-data-probe heater. The electrical metric of the air data probe heater is one or more of: i) phase relation between voltage across the resistive heating element and leakage current, which is conducted from the resistive heating element to a conductive sheath surrounding the resistive heating element; ii) a time-domain profile of leakage current through the heating element insulation during a full power cycle; and/or iii) high-frequency components of the electrical current conducted by the resistive heating element and/or the voltage across the resistive heating element.
