Software defined radios (SDRs) have redefined many areas of modern electronics, from enabling reconfigurable communications to rapid prototyping of new electronic support concepts. However, current implementations of SDRs are limited by the underlying electronic approaches used to realize them. Herein, we describe a novel photonically-enabled SDR (PESDR) that utilized the inherently broadband natu ...

The overall goal of this project is to develop an in-process defect monitoring and correction technique for additive manufacturing (AM) of aluminum alloy to improve repeatability for geometric dimensions, material properties, and quality. In Phase I, Sentient collaborated with Johns Hopkins University Applied Physics Lab, and successfully completed all proposed tasks demonstrating two key capabili ...

To reduce size, weight, power and cost (SWaP-c), military platforms have been evolving towards more integrated platforms that utilize all available space. For radiating systems, this will require exploring innovative design methods, materials and manufacturing approaches to realize cost-effective, customizable and conformal antennas. An attractive solution to this challenge is offered by additive ...

This project aims to develop a low-cost millimeter-wave (mmW) imaging system for ground vehicles, to operate in combination with a long-wave infrared (LWIR)camera. Such a system will mitigate the challenges of driving in degraded visual environments (DVE) including night time, fog, dust, or smoke by providing real-time image of the vehicle surrounding independent from the presence of naturally occ ...

Chemiresistors are an important class of electronic sensors that detect the presence of analytes/chemicals via a change in the resistance of a sensor element. A typical interdigitated electrode array is deposited onto an insulating substrate with metallic electrodes that have feature sizes in the micron range. The metal electrodes are typically sputter coated onto the substrate, using lithographic ...

Composites Automation LLC and partner University of Delaware Center for Composite Materials proposes to expand their previously developed software framework for void modeling in autoclave prepreg manufacturing to include process aids (vacuum bag, breathers, bleeders, release films) and their influence on the process, and develop methodologies to assess effects of material and technician variabilit ...

Modern DoD applications are benefiting from the proliferation of EO/IR sensor technology. As imagers become cheaper and smaller, they are being more widely deployed for a variety of scenarios. This trend is exemplified by the Navys Future Targeting System (FTS), which will provide laser designation, laser spot imaging, and some target location functions in a single 5.5-pound unit, replacing discre ...

To address the needs of Navy to successfully produce 7000 series aluminum alloy components, Sentient proposes to develop a hybrid additive manufacturing (AM) process for this topic. Hybrid AM use a secondary process (e.g. peening, burnishing) along with primary AM process to tightly control thermal profile and stress evolution locally and globally, resulting enhanced part quality (e.g. negligible ...

To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

We propose to develop an innovative concept of the high speed dynamic IRSP that combines components and devices from proven suppliers with novel system-level research topics from CDS and University of Delaware. Having previously built and delivered working LED IRSPs to users gives CDS a unique advantage. In line with system theme of the solicitation, our phase 1 research topics are focused on syst ...
