Abstract: A triggered data streaming system captures audio from an aircraft and generates an audio signal. Once the system obtains a trigger indicating a potential emergency on the aircraft, the system streams the audio signal to an external destination outside of the aircraft. The trigger may be an external trigger received from outside the aircraft or an internal trigger generated from sensors within the aircraft.

Abstract: A staggered multi-tone (SMT) modulator that includes a Fourier transform module that is coupled to an input for receiving a complex valued data frame and that transforms the complex valued data frame from a frequency domain into a time domain. A symmetry extractor module extracts a conjugate symmetric data frame and a conjugate antisymmetric data frame from the transformed complex data frame. A first circular shift module performs a circular rotational phase shift on the conjugate symmetric data frame. A first filter filters the phase shifted conjugate symmetric data frame. A second circular shift module performs a circular rotational phase shift on the conjugate antisymmetric data frame. A second filter filters the phase shifted conjugate antisymmetric data frame. A summing module sums the phase shifted conjugate symmetric data frame and the phase shifted conjugate antisymmetric data frame to generate a modulated data frame.

Abstract: A phase array antenna system includes a first panel comprising a first array of antennas in a first grid pattern for transmitting first signals, and a second panel comprising a second array of antennas in a second grid pattern for receiving second signals. The first panel and the second panel are fixedly disposed in a plane and co-located along a direction in in the plane. The first grid pattern is the same as the second grid pattern, and the first panel and the second panel are rotated by an angle.

Abstract: A cross-network communication system includes a plurality of client networks. The cross-network communication system includes a Service Negotiation Plane configured to forward messages between the plurality of client networks via a plurality of control interfaces, each of which corresponds to one of the plurality of client networks. Each of the plurality of control interfaces includes a first data guard that belongs to the corresponding client network. The first data guard is configured to prevent exfiltration of classified information or permit only particular types of messages to traverse the Service Negotiation Plane.

Abstract: An apparatus and method are provided for digital predistortion of an electrical signal to pre-compensate for nonlinear distortions in a nonlinear channel (e.g., a nonlinear channel including a high-power amplifier). The digital predistortion processor includes a nonlinear filter. Filter coefficients are determined using a modified input electrical signal having multiple simultaneous tones, using an iterative process which adapts the modified input electrical signal to reduce levels of intermodulation distortions in a modified output electrical signal.

Abstract: A transparent optical device configured to be used with an underlying device. The underlying device is configured to provide output light. The optical device is configured to transmit light from the underlying device through the optical device. The optical device includes first and second zones. The first zone includes a first plurality of transparent regions formed in the first zone allowing light to pass through from the underlying device. The second zone includes a second plurality of transparent regions formed in the second zone which allow light in the first spectrum to pass through from the underlying device at a different transmission efficiency than the first zone.

Abstract: A method of applying three-phase power to a transformer having limbs including a first limb, a second limb, and a third limb respectively wound with primary windings that include a first winding, a second winding, and a third winding, includes: generating alternating current (AC) voltages (AC voltages) including a first AC voltage, a second AC voltage, and a third AC voltage; initially not applying the AC voltages to the primary windings; monitoring a relative voltage between the first AC voltage and the second AC voltage; and based on results of monitoring, implementing a power-on sequence of sequentially applying various ones of the AC voltages to corresponding ones of the primary windings until all of the AC voltages are applied to all of the primary windings in a manner that balances flux across the limbs during and after the power-on sequence.

Abstract: An apparatus and method are provided for a night vision system including a transparent overlay display that transmit direct-view light representing an intensified image and emits display light representing a display image. The night vision system includes an intensifier with a flat exit face, an overlay display that is flat/planar, and planar, diffractive lens. The direct-view light and the display light exit the overlay display with the same phase curvature (e.g., a flat phase curvature). The planar, diffractive lens induces a spherical phase curvature on the light exiting the overlay display. The phase curvature induced by the planar, diffractive lens matches the phase curvature of a legacy intensifier in which the final element is fiberoptic inverting element with a curved exit face. Accordingly, the combination of the intensifier, overlay display, and planar, diffractive lens can replace the legacy intensifier while maintaining the design specifications of the night vision system.
