Abstract: A lightweight thermally dissipative EMI shield for electronics is composed of both metallic (e.g., conductive) and non-metallic (e.g., nonconductive) materials. The thermally dissipative EMI shield or cover may be formed of multiple layers of metallic or conductive materials and at least one layer of non-metallic or nonconductive material. There may be a conductive base layer, a lower intermediate nonconductive layer, an upper intermediate conductive layer, and an outer nonconductive layer. The conductive layers operate to thermally dissipate heat and suppress EMI, whereas the nonconductive layers provide lightweight rigidity and stiffness to support the EMI shield and protect components from foreign object ingress or damage of a circuit card or cover is coupled.

Abstract: An extensible open data framework asynchronously processes augments received in response to alterations in registered triggers. The framework includes an active data storage and an algorithm execution protocol. The active data storage includes short term data signals and long term data augments or emitter tracks. The execution protocol includes an execution thread pool having multiple threads that operate in parallel. The parallelization of the algorithm via the execution thread pool scales through multiple threads and cores to process data.

Abstract: A method of manufacturing a structurally competent, EMI-shielded IR window includes using a mathematical model that combines the Sotoodeh and Nag models to determine an optimal thickness and dopant concentration of a doped layer of GaAs or GaP. A slab of GaAs or GaP is prepared, and a doped layer of the same material having the optimal thickness and dopant concentration is applied thereto. In embodiments, the doped layer is applied by an HVPE method such as LP-HVPE, which can also provide enhanced GaAs transparency near 1 micron. The Drude model can be applied to assist in selecting an anti-reflective coating. If the model predicts that the requirements of an application cannot be met by a doped layer alone, a doped layer can be applied that exceeds the required IR transparency, and a metallic grid can be applied to improve the EMI shielding, thereby satisfying the requirements.

Abstract: Techniques are provided for jammer detection. A methodology implementing the techniques according to an embodiment includes estimating an angle of arrival of a jamming signal, the jamming signal included in a received signal, and generating a direction finding (DF) confidence indicator associated with the estimated angle of arrival. The method also includes extracting the jamming signal from the received signal. The method further includes correlating the extracted jamming signal with previously extracted jamming signals to generate a correlation score and using the correlation score as a uniqueness assessment of the extracted jamming signal. The method further includes identifying characteristics of the extracted jamming signal and generating a characterization confidence indicator. The method further includes demoting the extracted jamming signal to non-jammer status based on one or more of the DF confidence indicator, the uniqueness assessment, and the characterization confidence indicator.

Abstract: An apparatus for dampening at least one optical instrument on a military platform. The apparatus includes a plate adapted to hold at least one optical instrument. The apparatus also includes at least one dampening assembly having a first end operably engaged with the plate and an opposing second end operably engaged with a platform. The at least one dampening assembly is also adapted to reduce the movement of the plate and optical device from a ballistic event created by a ballistic device on the platform.

Abstract: A method, system, and computer readable medium for performing a generalized angle-based tracker for a target determines angle-based information from a target signal, and initializes a Stationary Surface Filter (SSF), a Moving Surface Filter (MSF), and a Pseudorange Kalman Filter (PKF) with the angle-based information. Next, the SSF and MSF are scored by the PKF. If the information is associated, then the SSF, MSF, and PKF are updated. It is determined if at least one plausible Constituent Kalman Filter (CKF) exists for the SSF and MSF. If at least one CKF exists for the SSF and no CKF exists for the MSF, then the target is stationary surface; if at least one CKF exists for the MSF and no CKF exists for the SSF, then the target is moving surface; if no CKF exists for both the SSF and the MSF, then the target is moving airborne.

Abstract: An anomaly detection system is disclosed. In an embodiment, the anomaly detection system includes an anomaly detection module and a warning indicator module. The anomaly detection module includes one or more auto-encoders that receive sensor data from a plurality of sensors. Each of the one or more auto-encoders receives sensor data from at least three different sensors of the plurality of sensors. By receiving data output from at least three of the sensors, the auto-encoder can recognize expected inter-related patterns from the sensor output. The warning indicator module compares an output of a given auto-encoder of the plurality of auto-encoders to an input of the given auto-encoder to obtain an error value, and then compares that error value against an error threshold. In response to the error value exceeding the error threshold, the warning indicator module issues a warning signal associated with the sensor data received by the given auto-encoder.

Abstract: An encapsulation block for a digital signal processing (DSP) block. The encapsulation block includes DSP block having an input terminal, an output terminal, and an input clock. The encapsulation block also includes pacing control network operatively connected with the input terminal, the output terminal, and the input clock of the DSP block. The input terminal of the DSP block is configured to receive a samples-in data stream inputted at a predefined clock period defined by the input clock. The output terminal of the DSP block is configured to receive a samples-out data stream outputted at a predefined paced parameter. The pacing control network is configured to control data flow at the samples-in data stream and the samples-out data stream independently of the DSP block.
