In 1999, the Navy and Marine Corps Public Health Center converted an HIV train-the-trainer program into a broader effort of preventing not just HIV, but also other sexually transmitted infections (STIs) and unplanned pregnancies. The premise for this broader approach was that a more comprehensive sexual health promotion message of STI, HIV, and unplanned pregnancy prevention is more likely to include at least one personally relevant concern for any given individual and is, therefore, more likely to be internalized and acted upon by the greatest number of individuals, and that risk reduction for any one of these consequences of sexual activity may reduce risk for all. This new effort was labeled the Sexual Health and Responsibility Program (SHARP). Within the Navy and Marine Corps, SHARP has become a focal and trusted source of sexual health promotion products, consultative services, and training, as well as a conduit for multidisciplinary collaboration and coordination. The existence of this central sexual health program normalizes integrated and comprehensive sexual health messages, enables efficiencies, promotes program and policy uniformity, and provides a forum for cross-organizational collaboration and continuous improvement.

Wireless mesh networks are systems of interconnected wireless access points that provide digital services to client devices via radio transmission. We consider the challenges of a communications planner who must quickly design a wireless mesh network, as might be expected during combat operations or in support of humanitarian assistance and disasterrelie foperations. We seeka network that maximizes client coverage area subject to constraints on network service, the technical characteristics of the available access points, and radio propagation over terrain. We create a nondifferentiable, nonconvex, nonlinear optimization problem and use a sampling algorithm to quickly find good solutions. We validate our formulation and solutions via numerical experiments and several field tests, and we demonstrate that our technique can generate network topologies capable of functioning in real-world scenarios. We construct a corresponding decision support tool that allows a communications planner to design working wireless mesh network topologies quickly, with no guesswork, and requiring very little expertise. The tool runs on a laptop, supports virtually any type of access point, uses terrain information freely downloadable from the Internet, and does not require any additional software or solver licenses.


During the weeks of September 28 and October 26, the team launched 23 flights over a nine-day period resulting in greater than 30 hours of combined flight. The tests, conducted within restricted airspace at Phillips Army Airfield, Aberdeen Proving Grounds, culminated with two 'powered' sailplanes sharing telemetry data and cooperatively and autonomously soaring at altitudes in excess of one kilometer and for flight durations of over five hours. The NRL-developed Autonomous Locator of Thermals (ALOFT) autonomous soaring algorithm guided NRL's aircraft. The PSU aircraft was guided onboard by the AVIA-developed AutoSOAR autonomous soaring algorithm, which drew inspiration from NRL's ALOFT techniques. AutoSOAR's addition of a series of atmospheric mapping and collision avoidance algorithms demonstrated in-flight cooperation between the two aircraft on multiple flights. "Autonomous soaring algorithms seek out naturally occurring areas of rising air called thermals," said Dr. Dan Edwards, aerospace engineer and principle investigator of the solar-soaring program. "Cooperative autonomous soaring combines data from multiple autonomous soaring aircraft to make a more complete measurement of the local atmospheric conditions. This atmospheric map is then integrated to guide both aircraft toward strong lift activity quicker than if it was just a single aircraft, a technique very similar to that used by a flock of soaring birds." Both aircraft demonstrated a robust autonomous soaring capability during the two weeks of testing. PSU's aircraft flew multiple 2.5-hour flights despite carrying a battery with only enough capacity for four minutes of motor run-time. NRL's best soaring flight was 5.3 hours while only running a motor-driven propeller for 27 minutes. Both aircraft rode thermals to altitudes in excess of 1,400 meters with several individual climbs in excess of 1,000 meters using nothing more than the power of the atmosphere. "These tests showed both the NRL and PSU's autonomous soaring algorithms are successful at finding and using thermals by themselves," Edwards said. "More importantly, this testing showed proof of concept on multiple occasions, with both aircraft finding thermals and 'calling' the other aircraft over to use the same area of lift to increase endurance of the swarm." Future testing will focus on reducing the separation distance such that both aircraft can actively soar in the same thermal at the same altitude. The team will also investigate the inclusion of solar photovoltaics to the cooperative autonomous soaring techniques, enabling long endurance flights of unmanned sailplanes using the power of the sun. Solar photovoltaics will allow conversion of solar radiation directly to electricity to charge batteries or provide power for longer endurance or payloads. NRL is developing "drop-in" power electronics and solar wings, which will enable charging batteries and aiming for overnight flight. The Solar Photovoltaic and Autonomous Soaring Base Program and the US Marine Corps' Expeditionary Energy Office Cooperative-Soaring Program are aimed to improve the availability of a 24-7 Information, Surveillance, and Reconnaissance (ISR) mission without using logistics fuel, benefitting the expeditionary warfighter by enhancing the endurance of existing and future UAV assets.


The present invention is a loadbearing device known by the Applicants as the Central Osteoarticular Relief and Performance Structured Load Distribution System (CORPS-LDS), which is worn by a user to help distribute the weight of a load being carried or borne by the user. More specifically, the weight is substantially shifted from the users shoulders to their hips while not overly inhibiting the users range of motion. Furthermore, it is an aspect of the CORPS-LDS to distribute the weight being carried in a manner that reduces the strain on the spine and back while lessening the metabolic expenditure of the user. Moreover, the present invention is a protective vest system that utilizes the present inventions CORPS-LDS.
