    Abstract: Apparatus and associated methods relate to improving measurement of metrics determined by laser air-data systems subject to unwanted background light. Such measurements are improved by estimating and excising the unwanted background light from the total light received by an optical receiver which receives a Doppler-shifted reflected portion of a projected beam of light backscattered by aerosols and air molecules of an atmosphere. The background light is estimated using a background-light rejection filter that receives the light received by the optical receiver after it has been filtered by a vapor cell filter and separates the light received by the optical receiver into a beam sampling portion and a complementary non-beam portion. The non-beam sampling portion is used to estimate the background light portion within the beam sampling portion, which also contains the Doppler-shifted reflected portion of the projected beam used for calculating the metrics of air data.

    Abstract: An ice detection sensor apparatus includes a strut body extending along a longitudinal axis. The strut body includes an axially extending wall extending around the longitudinal axis to surround an interior space, and an axial-facing end wall connected to an axial end of the axially extending wall. The axial-facing end wall partially bounds the interior space. A magneto strictive oscillator sensing element extends from the interior space, through the axial-facing end wall. The sensing element is engaged to the axial-facing end wall for oscillation along the longitudinal axis relative to the axial-facing end wall. A permanent magnet (PMG) element is integral with, e.g., monolithic with, the strut body.

    Abstract: 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.

    Abstract: 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.
