Sponsored by NAVAIR, Accudyne Systems completed a Phase 1 SBIR program, developing an equipment and process concept for cost-effective fabrication of composite rotary wing main rotor blade spars. The CH-53K spar was the study focus. The recommended work cell concept combines automated tape placement, woven fabric placement, and pick and place of 45° parallelograms to layup plies, then debulk and ...

A versatile and portable instrument for stray light detection and diagnosis at both visible and infrared wavelengths will be designed, built, and demonstrated. The core idea of the proposed approach is to use subaperture, rather than full aperture, illumination for stray light detection. The subaperture approach uses a scanning pencil beam (SPB) that provides information about the location of a s ...

The main objective of this project is to develop technologies for variable speaking speed synthesis, or Text-to-Speech (TTS). A TTS system converts written text into spoken language. There are numerous commercial TTS systems; however, most systems do not allow for speed control of the output speech. In the simulation-based virtual training system, TTS systems are used to generate the voice of the ...

In phase I, we have proven the feasibility of using the microwave cavity perturbation technique to detect and quantify DoS in marine aluminum alloys. We implemented an alpha version sensor prototype, characterized and validated its performance using ASTM G67 method. We also identified methods to further enhance the sensor sensitivity, so that DoS in the low (a few mg/cm2) to moderate range can be ...

There is an acute need for lightweight, articulating elbow and knee ballistic systems that provide protection against NIJ Level II threat projectiles. The goal of this SBIR Phase II program is to continue development and optimization of an innovative lightweight, articulating elbow and knee protection system that is capable of meeting current Level II protection requirements. The design success w ...

Long-wavelength infrared (LWIR) imaging has significant importance in military surveillance and target recognition, since human body radiation peaks in LWIR. Despite the enhanced wavelength coverage, the GaSb/InAs type-II Strained Layer Superlattice (SLS) detector still exhibits relatively high surface leakage current and its associated noises. With an industrially proven nano-material, we propose ...

The overall objective of this Phase II program is to continue and finalize the development of the dropsonde satellite data transmission device and back-end data retrieval system. This design and development effort will yield a number of prototype units to be integrated with the Yankee Environmental Systems dropsonde being developed concurrently. The combined device will be a more automated system ...

High resolution SAR imaging and Ground moving target indicator (GMTI) radar are of crucial to intelligence surveillance and reconnaissance operations. High resolution SAR imagery are often realized at the expense of wide bandwidth waveform, and to achieve long dwells over a wideband width, often the operating frequency band overlaps with other co-band radars, and it becomes necessary to notch out ...

The DataSoft Software Defined Radio (SDR) Tool Suite (STS) provides a new and enhanced capability to the SDR developers via two independent tools: the STS-WF Analysis Tool and the STS-Probe Toolbox. The STS-WF Analysis Tool can reduce cost and schedule by assessing new waveform (WF) and platform (PF) compatibilities along with guidelines from standard portability and compliance documents early in ...

The U.S. military’s next-generation radio system, JTRS, is based on Software Defined Radio (SDR) technology and will create new opportunities, methods, and applications for generating and sharing tactical data. One of the many challenges in realizing the JTRS vision is to create small, lightweight, embeddable devices that operate from battery power, meet the requirements for performance, SCA com ...
