ABSTRACT:A chip carrier for high power density electronics made from low CTE materials and embedded with an oscillating heat pipe will be applied to a real world satellite electronics device to transform high heat flux (e.g. 100-300W/cm2) at the device package to a lower heat flux at the heat sink areas - and do so with minimal thermal resistance. Deliverables at conclusion of two-year effort will ...

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:Innovative Technology Applications Company, LLC proposes the development of an analytical tool that predicts jet noise and engine performance for current and future generations of supersonic two- and three-stream engines. The goal is to provide robust and reliable noise predictions in minutes that can be used for design optimization. The physics-based approach will be capable of addressin ...

ABSTRACT:The proposed research effort will develop passive Oscillating Heat Pipe (OHP) structural heat spreaders to attach to small, ultra-high heat flux devices (e.g., GaN power amplifiers) and dissipate their heat loads uniformly across the spreaders' relatively large heat sinking surfaces - and do so with minimal thermal resistance. The research team will design, model, fabricate, test, and ana ...

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: 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 ...

ABSTRACT:Increasing emphasis on affordability of military systems has led to a number of advances in airframe production. For example, high speed machining (HSM) has made it possible to fabricate thin structures that provide improved performance. However, near-surface plastic strains induced by HSM or surface treatments can lead to excessive component distortion such that the component requires re ...

ABSTRACT:This Phase II project will include the research, development, implementation and deployment of a method, new image quality indicators (IQIs) and software algorithms to automatically assist in the verification of computed radiography (CR) image quality for nondestructive testing (NDT) of military airframes.Compared to existing IQIs and methods, the new approaches will more comprehensively, ...

ABSTRACT:In this phase II effort we will commercialize the high speed, high power, modified uni-traveling carrier (MUTC) photodiodes (PDs). To this end, we will develop reliable packaging solutions for discrete PDs, PD arrays, balanced PDs and waveguide based PDs. We will also transition the chip fabrication process for continuous, high volume supply of quality MUTC PD chips. In the first six mont ...
