3D Microfabrication of Beam Tunnels for High Power Vacuum Electronic Devices
Description:
NRL has developed a novel microfabrication process for creating highly precise, geometrically round tunnels in all-metal, photolithographically-formed structures for the purpose of transporting electron beams through vacuum electro-magnetic slow-wave circuits in the millimeter wave (mmW) and sub-mmW frequency ranges (approx. 90 GHz to over 1 THz).
Abstract
The Naval Research Laboratory (NRL) has developed a novel microfabrication process for creating highly precise, geometrically round tunnels in all-metal, photolithographically-formed structures for the purpose of transporting electron beams through vacuum electro-magnetic slow-wave circuits in the millimeter wave (mmW) and sub-mmW frequency ranges (approx. 90 GHz to over 1 THz). This patent-pending technique uses polymer monofilaments embedded in the photoresist to hold the shape of a beam tunnel during the UV-LIGA photolithographic process. The resulting quasi-3D structures are easily electro-formed with low-loss, high thermal conductivity metals, such as copper, to create both precise electromagnetic circuits and electron beam tunnels in a single process step. This technique can similarly create multiple beam tunnels of arbitrary cross sectional shape, waveguides, passive electromagnetic structures (e.g. filters), or a wide range of microfluidic devices.

Adaptable Reagentless Detector
Description:
NRL has developed a reusable biosensor that easily targets analytes, like toxins or hormones, with a controllable binding affinity. The sensor can be reused for subsequent sensing events once it is washed of analyte. It can be easily adapted to target other analytes due to its modular design. The biosensor's adaptability was demonstrated by modifying the maltose-sensing prototype to target the completely unrelated explosive TNT. The reagentless biosensor answers the Naval and commercial need for reusable sensors that continuously monitor analyte concentrations without reagents.
Abstract
The Naval Research Laboratory (NRL) has developed a reusable biosensor that easily targets analytes, like toxins or hormones, with a controllable binding affinity. The sensor can be reused for subsequent sensing events once it is washed of analyte. It can be easily adapted to target other analytes due to its modular design. The biosensor is self-assembled and consists of two co-functional entities. The first entity is a surface tethered biorecognition element, such as a receptor protein. The second entity is a multifunctional tethered modular arm that contains a point of surface attachment, a flexible DNA linker, and a dye label. The dye label is attached to a recognition element (an analog of the primary analyte) that interacts with the receptor protein. These two entities are self-assembled on the surface of a microtiter well and their close proximity, when the biorecognition elements bind the analog on the modular arm, results in fluorescence resonance energy transfer (FRET) between the dyes. Detection of the targeted analyte is achieved when the analyte displaces the analog on the arm and alters FRET in a quantifiable manner. The useful sensing range is easily altered and extended through the use of different protein mutants and the addition of a DNA complement to the DNA flexible linker. The biosensor's adaptability was demonstrated by modifying the maltose-sensing prototype to target the completely unrelated explosive TNT. The reagentless biosensor answers the Naval and commercial need for reusable sensors that continuously monitor analyte concentrations without reagents.
Benefits
Self-assembles in microtiter well plates - Requires only the presence of a target to function - Returns to baseline and is ready for reuse when washed free of analyte - Allows for the possibility of shipping and in-field use - Decreases test costs and logistical demands
Adaptive resampling classifier method and apparatus
Description:
According to the invention, an apparatus for classifying and sorting input data in a data stream includes a processor having a classifier input control with a first input and second input, an adaptive classifier, a ground truth data input, a ground truth resampling buffer, a source data re-sampling buffer, and an output. The processor is configured for sampling the input data with the input control, comparing one or more classes of the sampled input data with preset data classifications for determining the degree of mis-classification of data patterns, determining a probability proportional to the degree of mis-classification as a criterion for entry into a resampling buffer, entering data patterns causing mis-classification in a resampling buffer with a probability value proportional to the degree of mis-classification, comparing the data patterns to a ground truth source and aligning the data patterns with their associated data pattern labels employing the same decision outcome based on a mis-classification probability as applied to the resampling buffer to form a set of training data, and updating the adaptive classifier to correlate with the training data. These steps are repeated until a sufficient degree of data classification optimization is realized, with the output being an optimized data stream.

Aerial bogey discrimination technique
Description:
A computer-implemented analysis method is provided for identifying a flight trajectory of a bogey relative to earth's surface. The method includes a first step of obtaining first and second altitudes and velocities of the bogey separated by a first time interval. The second step calculates a first difference between the first and second velocities divided by the first time interval to obtain an acceleration vector. The third step determines the direction of the velocity vector. The fourth step determines whether direction of the second velocity vector exceeds an upward pointing threshold. The fifth step determines whether the acceleration vector is negative and substantially perpendicular to earth's surface as a second result being valid. The sixth step reports that the bogey represents a ballistic projectile in response to the first and second results.

Autonomous Underwater Vehicle Laboratory
FUNCTION: Studies coastal ocean processes with autonomous underwater vehicles (AUVs). Maintains, tests, ballasts, and prepares for deployment the Slocum Electric Glider AUV built by Webb Research Corporation. Slocums are designed to independently perform wide-area ocean surveys of temperature and salinity for up to about one month. DESCRIPTION: Slocum gliders are equipped with temperature/salinity/pressure sensors and with real-time satellite connection to the Iridium newtork. These gliders, unlike conventional AUVs, have no active propulsion system and instead rely on a battery-induced change of buoyancy and active control surfaces to glide through the coastal ocean from the surface to the bottom and from the bottom to the surface in a saw-tooth pattern. This system requires low amounts of power and therefore the gliders do not need to carry heavy battery payloads and can be deployed over long-duration missions (>30 days). An altimeter is used to prevent bottom collisions. Two-way communication of data/instructions occurs through Iridium satellite or freewave radio when the gliders are on the ocean surface. The central payload of the gliders can be equipped with various instruments for ocean measurements. The coastal gliders can dive to 200 meters depth. INSTRUMENTATION: A Slocum glider typically carries an altimeter and a Sea-Bird CTD (temperature, salinity, and depth) as part of a fundamental sensor faculty. Vertically averaged current velocity can be calculated using the difference of the actual glider track with the programmed track and surface current velocity can be calculated using the consecutive GPS fixes while at surface. Additional sensors include Wetlabs BB3 (optical backscattering), FL3 (fluorescence), and AUVB (total volume scattering).

An Army veteran is making the world a safer place with a military technology developed to train bomb-sniffing dogs.
Russ Hubbard, combat veteran and founder/CEO of Per Vivo Labs in Kingsport, Tennessee, donated a pair of Odor Trace devices to the Kingsport Police Department’s K-9 unit on Thursday.
The Naval Research Laboratory developed the mixed odor delivery device (MODD) for safely training explosive detection canines to detect homemade explosives. Homemade explosives are generally composed of two components, an oxidizer and a fuel. When mixed, the substance is volatile and at risk of detonation.
TechLink assisted Hubbard in licensing the patented Navy device in May. Since then, Hubbard sought the advice of his local K-9 police unit to perfect the final product.
The new training aid keeps the individual components separated within a container, then mixes the released vapors to facilitate safe and effective canine training for detection of homemade explosives.
“The Odor Trace Mixed Odor Delivery Device project has reached commercialization,” Hubbard said in an email to the Kingsport Times-News. “The initial production run is complete and assembled. The Odor Trace MODD will be available for commercial purchase on October 1. Two other local businesses have been instrumental in development and production. Partner support from Short Fuse Engineering located in Church Hill and Master Tool and Die of Kingsport have allowed Per Vivo Labs to quickly move from prototype to production rapidly.”
“The Kingsport Police Department would like to take this opportunity to sincerely thank Mr. Hubbard for his service and for this generous donation that he has made to our K-9 Unit,” according to a Kingsport Police Department news release.
The Odor Trace MODD is the second military technology that Hubbard has licensed. TechLink also helped Per Vivo Labs finalize a license for the Army’s rate-activated tether technology in February.
“It’s really great to see Russ moving the technology into the marketplace so quickly,” said TechLink’s Austin Leach.
