Coherent noise filtering for vehicle collision avoidance systems

Navy researchers have invented a way to ensure that driver-assist technologies are not inadvertently impaired by other vehicles with the same technology or environmental interference.

The Navy's system will have direct application in collision avoidance and lane change assistance modules in cars and trucks.

Air vehicle GPS backup navigation system

While advanced GPS systems provide highly accurate navigation, they are also susceptible to radio frequency interference, jamming, and occasional outages. When GPS fails, pilots must rely on one or more backup systems. The FAA initiated an Alternative Positioning, Navigation, and Timing (APNT) study to identify more robust means of GPS backup.

Navy engineers invented a triple redundancy solution for precise position, navigation and timing (PNT) in a low cost, size, weight, and power solution. GPS is accurate to a few meters, but the new Time-Space-Position-Information (TSPI) technology, using differential corrections, could be accurate to within a few centimeters.

Shipping container lift and leveling system

There are approximately 20 million shipping containers in the world and while the overwhelming majority are used for shipping, we are beginning to see alternative uses of these boxes. As multi-functional as these containers are, they remain very difficult to handle individually.

Army engineers have developed a method and components to make them easy to load and offload from a flatbed truck. The system also provides a means to level the container once it's on the ground.

Improved colorimetric explosive detection kit

The ability to detect trace explosive material can make a significant impact in prevention, mitigation, and deterrence in the global effort against terrorists.

Army scientists have developed a kit and reagents for colorimetric identification of explosives. Detection times are between instantaneous to one minute.

The kit can be used by the military, law enforcement, and intelligence personnel for safe, quick and reliable determination of suspected explosive chemicals.

Detection of multi-homed hardware on a computer network

In the communications network world, a multi-homed host (computer or network appliance) is one that has multiple connections to networks.

Multi-homed hosts present a security concern as they can be used to bypass the firewall between an internal network and the Internet.

To aid network administrators with the identification of multi-homed devices, Navy scientists and engineers are using the internal clocks present on all network devices as unique identifiers to monitor and collect traffic across the network.

Micro-atomizer

Research in inhalation toxicology requires the ability to generate stable aerosol concentrations of respirable particle size in a consistent manner from day to day and experiment to experiment.

Aerosol deposition in the upper airways of the human is generally achieved by a particle size between about 2.5 and 10 microns (μm) aerosol mass median aerodynamic diameter (MMAD), with the larger particles depositing in the larger airways.

Army scientists and engineers have developed a micro-atomizer to produce stable aerosol concentrations having an aerosol MMAD from 1 – 6 microns with liquid feed rates of 10 to 1000 microliters per hour.

Detection of heavy metals by means of fluorescence change detectable by the naked eye

Many pollution problems could be mitigated if an easy, in-situ analytical method existed to indicate the presence of contaminated water.

Navy researchers have developed a simple, easily scaled process for producing fluorescent nanoparticles, including quantum dots that are relatively non-toxic and environmentally stable in both air and water.
