Abstract: A laser transmission assembly for shearography and related systems utilizing transmissive geometric phase plate pairs in place of Risley prism pairs or movable mirrors therein. Transmissive geometric phase plates provide for a system that is more compact than systems utilizing mirrors or Risley prism pairs while maintaining or improving the adjustability of the system and further offering beamshaping to provide desired illumination patterns.

Abstract: Techniques to provide compression and/or decompression. A method includes obtaining a first set of control points specifying a first set of compression ratios corresponding to respective first regions of a compression domain, and minimum and maximum uncompressed values within the compression domain. The method can further include scaling the first set of control points based on the minimum and maximum uncompressed values to obtain a scaled set of control points, wherein a first scaled control point is located at the minimum uncompressed value, and a last scaled control point is located at the maximum uncompressed value. The method can further include adjusting at least one scaled control point such that a first slope does not exceed 1. The method can further include compressing or decompressing between the compression domain and a range of compressed values, wherein a respective compression ratio corresponds to a respective slope of the set of slopes.

Abstract: An antenna assembly includes a balanced antenna feed configured to receive a differential signal and a ground plane. The assembly further includes a first conductive dipole arm in planar alignment with a surface of the ground plane and a second conductive dipole arm in planar alignment with the surface of the ground plane and adjacent to the first conductive dipole arm. The assembly further includes a first feedline in electrical communication with the first conductive dipole arm and the balanced antenna feed and a second feedline in electrical communication with the second conductive dipole arm and the balanced antenna feed. The assembly further includes a conductive wall (“H-wall”) in electrical communication with the ground plane and having an end adjacent to, and physically separate from, the second conductive dipole arm. The H-wall has an axial length orthogonal to the ground plane.

Abstract: Techniques are provided for actively controlling a communications bus to mitigate threats, including cyber-attacks. A methodology implementing the techniques according to an embodiment includes detecting a threat in a message that is being transmitted between nodes on the communications bus. The message comprises one or more message frames and the threat detection is based on analysis of an initial portion of the message frame. The method further includes actively controlling the bus, based on the threat detection, to prevent the remaining portion of the message frame from delivering the threat to one or more of the nodes on the bus. Actively controlling the bus includes isolating nodes from the bus and/or overwriting data in the remaining portion of the message frame to invalidate the message frame or to remove the threat from the message frame.

Abstract: A secure system includes a data port, a network on chip (NoC) module, a processor communicatively coupled to the NoC module, a communication interface operatively coupled to the processor and to the data port, an electronic field-programmable gate array (eFPGA) configuration module operatively coupled to the NoC module, and a clock operatively coupled to the NoC module. In a first modality, the communication interface is at least partially disabled. In a second modality, the communication interface is at least partially disabled, boundary scan operations are disabled, a RESET signal is held in a constant state, and/or redacted code is rendered inoperable. In a third modality, the communication interface is at least partially enabled to send and receive commands and data via the data port, the boundary scan operations are enabled, the RESET signal is not held in the constant state, and/or the redacted code is operable.

Abstract: Systems and methods for sorting signals. One example of a method includes receiving a plurality of data vectors representing a plurality of signals, establishing a sparse primary grid including at least one primary cell in which at least one data vector has been received, based on a first number of data vectors received within the primary cell exceeding a first threshold value, establishing a sparse secondary grid within the primary cell, the sparse secondary grid including at least one secondary cell in which one or more data vectors have been received, based on a second number of data vectors received within the at least one secondary cell exceeding a second threshold value, establishing a first smart object corresponding to the at least one secondary cell, and associating the one or more data vectors received within the at least one secondary cell with the first smart object.

Abstract: A particle accelerator random number generator system comprises a particle accelerator, a particle event detector, and a processing application. Operation steps include initiating the particle accelerator; detecting a particle event by the particle event detector; recording a binary event from the detected particle event; determining if sufficient binary events have been recorded for the desired random number strength; if not, return to the step of detecting a particle event; if so, converting the random number binary string to a random number generated hexadecimal; applying the random number generated hexadecimal string for an encryption key; and using the random number hexadecimal key to encrypt an application.
