Users of additive manufacturing machines expect the highest quality when it comes to the mechanical properties of parts, the usability of the machines and associated processes, and overall machine design. The main contributor to the quality of the part is the involvement of process-related by-products originating from the melting process. To handle these by-products in additive manufacturing - in ...

We propose to develop tunable, high-power handling, low-loss phase-to-amplitude conversion photonic-integrated circuit (PIC) based device on heterogeneous SiN platform. The use of SiN for waveguide is the key to meet the stringent requirements, while additional heterogeneously integrated components are the key to enable tuning and locking of the phase-to-amplitude device. Nexus Photonics, realizi ...

We propose a serially concatenated switchable asymmetric Mach Zehnder switching network on a silicon nitride photonic integrated circuit platform to provide flexible and switchable demodulation of signals from less than 1 GHz to greater than 45 GHz. The silicon nitride platform provides a low size weight and power solution while reducing the stabilization requirements and providing long path lengt ...

Hemp-based clothing are excellent for outdoor active wear, due to high strength, UV-protective qualities, mold resistance, and excellent moisture absorption and desorption. While academic research on hemp-based textiles in the US is increasing, it has naturally also become an area of interest to competing countries. Specifically, China is outperforming the US in hemp fiber technological advanceme ...

Hepburn and Sons LLC teamed with North Carolina State University (NCSU) proposes an analysis of alternatives (AoA) to design and optimize a megawatt class, solid state transformer rectifier (SSTR) supporting maintainability of U.S. Navy shipboard power infrastructure. The design will convert 13.8kV AC to +-850V DC with modular, line-replaceable units (LRUs) that are compact and lightweight such th ...

Hemp fibers have been used in textile applications for thousands of years, but have been limited to textiles for home furnishing, rope, sacks, and other non-clothing textile applications. However, new treatment methods for hemp fibers to improve their hand, as well hemp’s general softening properties with time and wear, make these fibers attractive for use in performance clothing due to hemp’s ...

Hepburn and Sons LLC proposes to design a ground fault detection system for 440VAC three phase radial Navy shipboard power distribution, while teaming with their partner Florida State University, Center for Advanced Power Systems (FSU CAPS). Existing Navy ground fault detection systems can detect and locate single line to ground faults on a given phase, but a second ground fault on a separate phas ...

Detecting and Avoiding (DAA) manned aircraft from small Unmanned Aircraft Systems (sUAS) remains the unsolved problem for safe integration of sUAS into civil airspaces where Navy UAS must pay Due Regard to the laws of civil aviation. The difficulties are manifold. The solution requires both ultra-low SWaP sensors that track aircraft over long ranges, providing 360o field-of-regard (FOR), and often ...

NanoSonic is a small, advanced materials company that specializes in the development and manufacturing of state-of-the-art structural composites that are not commercially available.  Here, NanoSonic shall produce aircraft composites using additive manufacturing (AM) techniques with a commercial scalable method for revitalizing carbon fiber reclaimed from end-of-life and aircraft composite scraps. ...

Both acoustic and electromagnetic waves exert forces of radiation on targets in their path of propagation. The radiation force (pressure) results from the change in wave momentum due to scattering by the target, averaged over one period of oscillation.  Modulated radiation pressure (MRP) utilizes the acoustic radiation force by using a double-sided suppressed carrier modulated (DSB-SCM) incident ...
