Abstract: A method for discriminating between spoofed and valid ADS-B tracks includes applying a plurality of spoofing detection tests to an ADS-B waveform, applying weighting factors to the resulting test scores, and combining the weighted scores to obtain a confidence level indicating whether the ADS-B track is valid or spoofed. The detection tests can include power level validation, Doppler offset, ADS-B rules-based analysis, multi-band detection, track origination detection, and antenna diversity. The selection of applied detection tests and/or weighting factors can be adjusted and/or selected from corresponding libraries, according to operating conditions. Tracks can be displayed together with confidence level indications, and/or excluded from display if their confidence levels are below an adjustable threshold. Weighting factors can be chosen and/or updated by a machine learning model according to success in detecting simulated and/or actual spoofed tracks. A spoofing attack can be declared according to the number of spoofed tracks detected.

Abstract: An integrated circuit structure includes (i) a first layer including a first metal, (ii) a second layer above and in contact with the first layer, the second layer including a resistive material, and (iii) a third layer above and in contact with the second layer, the third layer including a second metal. In an example, the resistive material is different from one or both the first metal and the second metal. An interconnect component is above and in contact with the second layer. In an example, the interconnect component is a solder bump or a solder ball. In an example, a resistivity of the resistive material of the second layer is at least 20%, or at least 50% greater than a resistivity of each of the first and third layers. In an example, the resistive material includes a third metal different from the first and second metals and/or a metalloid.

Abstract: A navigation device includes a display, an electromagnetic radiation (EMR) receiver, and one or more processors operatively coupled to the display and the EMR receiver. The one or more processors are configured to cause the display, in a first mode of operation, to graphically render a navigation view. The navigation view includes (i) a first informational element relating to a geographic location of the navigation device and (ii) one or both of a compass rose and a geographic map. The one or more processors are further configured to cause the display, in a second mode of operation and responsive to receiving an EMR signal via the EMR receiver, to render an informational view including a second informational element, where the informational view at least partially obscures the navigation view.

Abstract: A liquid-cooled printed circuit board chassis, such as a Eurocard chassis, is manufactured without brazing by 3D printing a plurality of components, smoothing and completing the components by subtractive manufacture, and then aligning and assembling the final chassis, all without application of heat. Horizontal cooling channels 3D printed within the chassis components are in thermal contact with board slots, and are divided into subchannels by closely spaced internal walls that function as thermal baffles. The baffles are tilted at oblique angles to increase their cooling efficiency, and to enable AM manufacture without temporary support structures. Elastomer seals between components can connect the cooling channels to vertical connecting channels. EMI seals can be formed between the components by EMI gaskets. The components can be aligned by alignment pins, and joined together by bolts, screws, and/or adhesives. An intermediate horizontal extension can be included to accommodate shorter printed circuit boards.

Abstract: Techniques are provided for non-integer interpolation for signal sampling. A system implementing the techniques according to an embodiment includes a memory configured to store frequency values associated with an input signal sampled at a first clock rate. The system also includes a clock phase detector configured to detect phase alignment between a first clock signal associated with the first clock rate and a second clock signal associated with a second clock rate. The system further includes a read circuit configured to adjust an interpolation time interval in response to the detected phase alignment and to read the frequency values from the memory at the adjusted interpolation time interval. The system further includes a phase accumulator configured to accumulated phase as a sum of the frequency values read from the memory. The system further includes a waveform generator configured to generate an output waveform sample based on the accumulated phase.

Abstract: A shock absorbing apparatus that includes a baseplate adapted to be mounted on a platform, a flexure member that operably engages with the baseplate, and a mounting plate that operably engages with the flexure member. The mounting plate is free from direct engagement with the baseplate and is moveable between a neutral position and a translated position with respect to the baseplate. The mounting plate is also adapted to hold a device. The flexure member is adapted to absorb shock forces caused by a ballistic shock event or a projectile motion event in proximity to or applied on the platform.

Abstract: A system and method is provided to characterize optical properties (Scattering, attenuation, de-polarization) of a light-transmitting medium and local environment, by determining a scattering rate of light through a medium, wherein determining the scattering rate of light through the medium is accomplished by utilizing polarized light transmitted from an optical source. The system and method performs a function based on the characterized optical properties of the medium, wherein the function is one of, for example: detection of objects embedded in the medium, object ranging through the medium, or deblurring of images acquired through the medium.

Abstract: An optical detection system uses high-resolution holographic filters for target detection within a very-large field of view image acquired with a reflector. The holographic filter acts as an optical computer, mixing phase and amplitude information of known targets with light from the scene, automatically enhancing portions of the image that match threat objects or other object of interest. A lens forming a Fourier transform of the entire scene is used, and within that transform, the holographic information of a target or multiple targets is added. By acting as an inverse optical transfer function, the hologram gathers the target information to single point, and removes non-target background. Amplification is done by using a laser-illuminated hologram to create a phase-amplitude filter in a photorefractive material at the transform plane. By mixing the hologram and the scene at the transform plane, the matching is enhanced regardless of target location in the scene.
