In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

Training in the symptoms of Spatial Disorientation (SD) has shown to be valuable in aiding pilots to recognize its onset and provide a means for mitigating its effects, but such demonstrations have traditionally been associated with specialized equipment and devices. Since the vast majority of pilots for the commercial aviation jet fleet are trained (or recertified) on 6-degree-of-freedom (DOF) h ...

Conceptual design tools for rotorcraft are used to size vehicles for intended flight operations, as well as reveal trends on the relative benefits certain configuration choices have on the resulting aircraft performance. This information is useful for indicating potentially valuable areas for further technology development that would enhance rotorcraft capabilities. These tools must therefore co ...

United Silicon Carbide, Inc. proposes to develop a novel compact, efficient and high-temperature power module, based on unique co-packaging approach of normally-off silicon (Si) MOSFET with silicon carbide (SiC) normally-on power JFET in a cascode configuration. A much desired silicon MOS gate control is provided readily compatible with the conventional gate drivers, making a proposed module a plu ...

Solar-blind ultraviolet (UV) imaging is critically important in the fields of space astronomy, national defense, and bio-chemistry. United Silicon Carbide, Inc. proposes to develop and commercialize a unique JFET-based monolithically-integrated radiation-tolerant solar blind active pixel sensor (APS) UV imager. Silicon carbide is the ideal materials system due to its negligible dark currents, exc ...

NASA needs narrow linewidth lasers in the 1.5 or 2 micron wavelength regime for Lidar applications. The laser should be tunable by several nm and frequency modulated by 5GHz. Princeton Optronics has developed ultra-stable narrow linewidth diode pumped solid state lasers and developed high power Vertical Cavity Surface Emitting Laser (VCSEL) devices for fiber laser pumps as well as VCSEL pumped CW ...

In this proposal, AlphaSense, Inc. (AI) and the Carnegie Mellon University (CMU) detail the development of RF front end based on MEMS components for miniaturized digital EVA radio. Key innovations of our approach include: a) the use of a novel parallel receiver front end architecture based on MEMS components, b) a novel design of a high Q mixer-filter for RF mixing and IF filtering, and c) the imp ...

While past research has demonstrated the utility and benefits to be gained with the application of advanced rotor system control concepts, none have been implemented to date on a production military or commercial rotorcraft. A key contributor to this fact is the inherent cost associated with installation and maintenance of these control systems, since many system designs require the replacement o ...

Broadband focal plane arrays, operating in UV-to-SWIR wavelength range, are required for atmospheric monitoring of greenhouse gases. Currently, separate image sensors are used for different spectral sub-bands: GaN for UV, Si for visible, and InGaAs for SWIR, requiring expensive component-level integration for hyper-spectral imaging. Also, the size of the InGaAs focal plane arrays is currently limi ...

Many large-scale numerical simulations can be broken down into common mathematical routines. While the applications may differ, the need to perform functions such as matrix solves, Fourier transforms, or eigenvalue analysis routinely arise. Consequently, targeting fast, efficient implementations of these methods will benefit a large number of applications. Graphics Processing Units (GPUs) are e ...
