This Small Business Innovation Research Phase I proposal describes a latching anti-tamper (AT) stress sensor (LATSS) for volumetric protection of military systems. LATSS devices are intended to passively detect and remember if a change in some mechanical aspect of the shield enclosing a protected volume has occurred and provide a signal that can be queried to report the change. They are based on ...

This Small Business Innovation Research Phase I project proposal describes a program to research and develop a method for producing a radiation-hard solid-state Magnetic Patch Memory (MPM) deposited on top of a wafer from an untrusted facility and programmed in a trusted facility. MPM can be erased with zero remanence in the event of tampering to render the device it protects impossible to revers ...

Hyperspectral imaging arrays offer far more data and the ability to discriminate objects being observed. Continued difficulties with applying HgCdTe materials, especially for LWIR, present an opportunity for the development of alternate materials. One such candidate for MWIR/LWIR photodetectors are InAsSb alloys and short period Type-II superlattices based on InAs/GaInSb. This superlattice struc ...

SVT Associates proposes an innovative atomic Hydrogen enhanced growth and surface preparation technique for high performance type-II superlattice focal plane array fabrication. This material system is capable of infrared detection from 2 to > 30 micron, depending on layer composition and thickness. Photodetector arrays using this material are of great interest to the DoD for various applications ...

Freeform optical surfaces offer advantages over axis-symmetric surfaces in the ability to reduce optical sizes, increase performance and reduce aberrations. However, the description, fabrication and metrology of these surfaces can be difficult and costly, prohibiting their ability to achieve their full potential. Fabrication of these surfaces can be difficult, since they are not axis-symmetric and ...

The results of the proposed Omni-Directional Sensor Mount research and development will be greater usefulness of both old and new Ballistic Missile Defense Organization (BMDO) sensor technology. The innovative design adapts novel patented and patent pending technology, to provide a double-jointed sensor mount which is singularity and gimbal lock-free. The device merges novel patented technology wi ...

A significant need exists for power switching transistors used in spacecraft power management and distribution (PMAD) modules which can operate at high temperatures (400 C). SVT Associates proposes to meet-the need for high temperature electronic devices with an innovative large gate-width GaN junction field effect transistor (JFET). The Phase I program will demonstrate transistors based on N and ...

SVT Associates proposes to demonstrate UV surface emitting lasers in the III-N material system using a proprietary epitaxial metal layer to form the bottom mirror. This metal layer significantly reduces the material deposition time and acts as a lattice matched layer for depositing the laser structure. Significant reduction in diode series resistance is achieved since the metal layer acts as a oh ...

Space-based systems must dissipate tens to hundreds of watts for communications, housekeeping, etc. TRA proposes a novel thermal strap which would allow efficient energy conduction from heat sources to the structure of the spacecraft or to heat dissipation units. The thermal strap would utilize high thermal conductivity graphite fibers. Techniques for joining the fibers to end connectors will be i ...
