OEwaves Inc. and AMO Physics Center of JILA propose to develop a novel monolithic ultra-stable portable whispering gallery mode resonator suitable for operation in a wide range of environmental conditions. The resonator will deliver the same performance as the best existing high-end laboratory Fabry-Perot resonatorswhich are large, expensive, and fragile table-mounted instrumentsbut in a robust 10 ...

Highly stable, ultra-narrow linewidth frequency references are required for current and next generation timing systems. Timing systems with improved accuracy from primary clocks to fieldable references all require laser oscillators with improved inherent stability (time scales shorter than ~ 1 second). This proposal describes a novel frequency reference based on spectral hole burning in rare-ear ...

We describe our efforts towards compact ultrahigh-Q 698-nm microcavity stabilization at 1e10-15 frequency instability at 1 second and chip-scale integration for portable precision optical lattice clocks. This advancement is based on state-of-the-art measurements and preliminary results by our team, enabled by the highest quality factor optical resonators (Q f 2e1010) measured to-date. The resonat ...

Boston Engineering"s Advanced Systems Group and Dr. Holly Yanco"s team at the University of Massachusetts at Lowell propose to develop a design science for robot operator interfaces and demonstrate its application through existing design tools and prototype systems that reduce operator training time, maximize the ability of an operator - robot team to maintain synchronization, and provide a baseli ...

Currently Unmanned Ground Vehicles are teleoperated, requiring operators to be both vigilant and fully engaged throughout the operation. While increasing the level of autonomy of UGVs potentially reduces both the workload and cognitive load on operators, realizing the promise of autonomy is difficult in deployment. Remote operation of UGVs is subject to unreliable communication and mobility chall ...

Emergency departments, trauma centers, and military field physicians have a critical need for a simple, easy-to-use, and reliable method of monitoring the onset of hemorrhagic shock that is able to predict onset during the compensatory phase, before syncope and cardiac collapse signaled by a rapid drop in blood pressure. In collaboration with Dr. Michael Joyner"s laboratory at the Mayo Clinic, RMD ...

Continuous monitoring of body chemistries for metabolic monitoring, monitoring concentration of biothreats, early detection of sickness, and stress monitoring has the potential to enhance warrior performance. Currently available sensors are inaccurate and have short lifetimes, primarily due to the body"s foreign body response (FBR) to implanted materials. PROFUSA"s tissue-integrating sensor platfo ...

This proposal is to develop a new system for Adaptive Visualization of Social Networks (ADVIS). Numerous social network visualization systems have been produced in recent years. But even in the few top systems cognitive science and design principles have been applied in an ad hoc and non-systemic manner. Accordingly, each visualization system is a one-of, which may be fine-tuned to a particular ...

We propose to develop and evaluate a social media visualization testbed, using a novel first-principles design approach based on visual thinking algorithms(VTA"s). Much like software design patterns, VTA"s are reusable blueprints for design of new interactive visualizations. VTA's describe the steps in the visual thinking process that capture both operations occurring in a computer and in the ...

To address DARPA need to overcome the growing problems of co-site interference encountered in the modern military communications systems, RST Scientific Research, Inc. ("RST") proposes to develop a new low size, low cost low power closed-loop controlled high-Q frequency agile filter-bank assembly with RF channel select capability from 20 MHz to 30 GHz. The new filter-bank design to be inserted in ...
