ABSTRACT:Cognitive skills/capabilities are important for the military personnel to fulfill tasks and to ensure mission efficiency and success. In the past decade, there are abundant researches suggesting that non-invasive brain stimulation via transcranial direct current stimulation (tDCS) holds great promise to enhance a soldier's cognitive performances. Although models to predict the tDCS curren ...

ABSTRACT:Modulator linearity and efficiency, in addition to bandwidth, are important parameters in characterizing a modulator. In general, improving modulation efficiency is highly desirable since higher modulation efficiency allows lower RF signal to impose equivalent change in the optical beam whereas improved linearity increases the dynamic range available to analog signals conveyed and process ...

ABSTRACT:Hyperspectral imaging is a technique used to simultaneously capture spatial and spectral information of an object scene, making it a valuable technique for applications in remote sensing and military battlefield environments. In the case of long wave infrared (LWIR) imaging, a hyperspectral approach offers an opportunity to improve upon the detection capabilities of standard broadband sen ...

ABSTRACT: Sierra Engineering Inc. (Sierra) believes that existing chemical kinetic models can be efficiently incorporated into commercial CFD codes to predict the mixing, pyrolysis, soot formation and carbon deposition within film cooled rocket engines. During this Phase I STTR effort we will demonstrate that this analysis capability is practical and that we can generate appropriate model validati ...

ABSTRACT: Under the proposed effort, PSI will leverage a novel pmmW imaging technology developed under a prior Navy program to realize the low size, weight, and power sensors required for UAV implementation. This technology is based on an optical upconverted distributed aperture technology that can make use of the full aperture of the aircraft thereby maximizing achievable resolution. This sensor ...

A new class of high-performance, low-SWaP computational devices is emerging based on increasingly diverse architectures. This diversity is improving performance, but comes at the cost of increased programming complexity. Each architecture requires variances in programming environment and model, typically distinguished by the type of parallelism supported by the hardware, limiting software portabil ...

We propose to monolithically integrate an infrared light emitting diode (IRLED) array on the backside of a GaAs substrate whose frontside contains an array of driver circuits. We will develop smaller GaAs substrate via technology to enable smaller pixel pitch and realize a large-scale GaAs-SLEDS read-in integrated circuit (RIIC). Our team consists of experts in IRLED fabrication, RIIC design, Ga ...

Continuously advancing ballistic missile threats require an interceptor missile system which has greater basing flexibility and highly advanced performance in terms of burnout velocity and Divert and Attitude Control (DACS). Liquid systems are the ideal candidate to fit this role because of higher performance than solids; however, they tend to be a significant safety risk due to toxicity, corrosi ...

This SBIR Phase II effort will be aimed towards designing and testing a controllable missile lateral support system (LSS) that reacts automatically to shock and vibration inputs. A sub-scale lateral support system (LSS) assembly consisting of six jacking feet and a full-scale LSS jacking feet unit will be fabricated and tested. The electromechanically actuated LSS will offer controllable damping t ...

Lyme disease is a vector-borne illness caused by infection with B. burgdorferi. Hard ticks (Ixodes spp.) acquire the spirochete from a natural reservoir of small mammals; transmission to humans occurs via the bite of an infected tick. By any measure, Lyme disease is one of the most serious emerging infectious diseases that threaten public health in the United States. New estimates from the CDC ind ...
