We propose to develop hybrid SAR/ISAR imaging to provide enhanced imageries with both plan-view and broadside profile-view of ships and hence improve the performance of ship/small craft classification. In cases that radar and targets are both moving, good radar imageries may not be obtained by either SAR or ISAR. It can be generated through the hybrid SAR/ISAR mechanisms. The basic theoretical dev ...

This Phase II SBIR is focused on expanding on the Phase I results regarding reballing Ball Grid Array (BGA) parts from tin-silver-copper (SAC305) solder to SnPb eutectic solder. Other solder alloys, printed wiring board surface finishes, the die-package impact, solder ball pitch, different size BGAs (ball count), and test methodologies will be examined to fully characterize this process. For the m ...

Intelligent Automation, Inc (IAI) team is proposing a novel Agent Based Distributed Control (ABDC) framework for Next Generation Integrated Power Systems (NGIPS). ABDC addresses the issue of monitoring and adjusting energy generation, energy storage, and system loads for increased efficiency, enhanced shipboard performance during normal/faulty conditions. It has the capability to work seamlessly w ...

Knowledge of the potential failure mechanisms and their drivers provides a foundation to this proposal, which is designed to assess the impacts of the harsh environmental stresses on the various packaging technologies proposed. From this assessment, the DoD and their supply chain will have a clear understanding of how the transition to Pb-free electronic packaging may change the mean time between ...

The proposed SBIR effort seeks to develop and validate a skill acquisition/decay model, novel objective metrics, and simulation-based training strategies for the prevention of laparoscopic surgical skills attrition. The ultimate goal of this effort is to integrate the resulting system within standardized military medical training curricula for enhanced training and sustainment of these critical sk ...

The proposed Phase II effort involves development and demonstration of an all-carbon fiber/epoxy aft shell body and integrated aft pusher assembly for gun launched hypervelocity applications. The all-carbon fiber technology is the selected approach for this effort, owing to the cost effectiveness, long term availability, and broad utility of this material and manufacturing process methods for mili ...

The overall goal at the end of this multi-phase program is to develop an energy harvester composed of rectenna arrays that are connected in parallel that harness significant amounts of infrared electromagnetic energy. The ultimate systems will be capable of harvesting watts, kilowatts of energy using these structures fabricated in parallel on a large scale, or for smaller scale application specifi ...

A zinc-water battery system for use in underwater environments is proposed, with an expected energy density significantly higher than lithium-ion batteries and slightly less than zinc-air batteries. The research proposed utilizes a concentrated electrolyte, which when combined with an outside water supply on a catalytic electrode surface acts as cathode of the zinc-water cell. The technology is lo ...

Rotors and their associated dynamic components operate in high-cycle and environmentally harsh conditions. Accurate rotor load predictions are crucial part of rotor analysis and design. Lag damping poses a challenge for rotor load analysis due to the difficulty of incorporating lag damper effects into comprehensive rotor analysis. The key challenge in effectively predicting the lead-lag motions an ...

Imperium, and its partner Oceaneering, propose a fast, accurate, reliable, underwater hull inspection system based on Imperium"s unique ultrasound camera technology. The proposed device generates images which are striking for its clarity and simplicity. It is based on a patented 2D ultrasound array with 120 rows by 120 columns of individual piezoelectric elements. The device has performance which ...
