Abstract

Sensor interconnects and supports and methods of making them utilize phonon disruptors for increased thermal resistance while maintaining acceptable electrical signal quality in materials. Phonon disruptors include, but are not limited to, structural features such as interfaces, grain boundaries, and point scattering sites, for example, that are designed to scatter heat carriers while allowing electrons to pass through the material. Some embodiments herein involve designing selected stacks of alternating or sequential material pairs within sensor interconnects.

Abstract

A testing device is provided that evaluates the operating performance of radio frequency (RF) emitting devices such as a counter-unmanned aircraft system (C-UAS) device. The testing device allows an operator, with limited RF knowledge, to conduct testing on a C-UAS device and quickly verify functionality in any location with no data analysis. The testing device provides a simplified and portable method to test the RF output of devices such as C-UAS. Since C-UAS devices use RF power to disrupt their UAS target, the performance can be assessed by verifying the RF power level emitted by the C-UAS device. In order to do this the testing device measures and assesses the RF power levels in the bands that the C-UAS device emits radio frequency energy.

Abstract

A microprocessor computer system for secure/high assurance/safety critical computing includes a hardware subsystem having a plurality of cache controller and cache bank modules including cache bank and memory cell hardware permission bits for managing and controlling access to system resources. A computer security framework subsystem includes a hierarchy of access layers comprising top layers and lower layers. The permission bits provide hardware level computer security primitives for a computer operating system. The top layers are completely trusted and the lower layers are moderately trusted to completely untrusted. The top layers include a trusted operating system layer that executes management and control of the system resources and permission bits. The permission bits define limits for a hardware execution security mechanism for less trusted to completely untrusted software. Exceeding bounds of the security mechanism results in a hardware exception thereby blocking all attempts to access or modify resources outside the security mechanism.
