Fast Rope Insertion Technology

The current Fast Rope Insertion and Extraction System (FRIES) system in use for tactical military operations is challenged by increasing operator loads and new platform applications.   There is a need for a safer method to rapidly descend in a controlled manner with a descend-default design and still allow the operator to  quickly detach in a manner consistent with their experience with other harness systems.  The Fast Rope Insertion System was designed by US Air Force Academy cadets and faculty in response to an Air Force Research Laboratory (AFRL) university design challenge.

Atmospheric Optical Turbulence Monitoring and Prediction

Guidestar’s atmospheric optical turbulence sensing technology remotely measures atmospheric turbulence strength.  Guidestar uses these measurements in combination with a proprietary model to estimate a number of localized weather parameters to support operational decision making.  In addition, Guidestar’s model can use weather forecast data to predict atmospheric optical turbulence.

SAGA: Measuring Similarity between Data Sets

This invention measures similarities between sets of data. The data could be natural language documents or articles, product descriptions, queries, computer code, metadata, or measurements from any real-world objects or processes. The technology is able to determine similarities between data sets without needing to know how they interact. Omitting duplicate pieces of data allows the technology to provide more accurate results. Additionally, this technology can provide patterns over time of the data entered. This invention takes a holistic view of the data to make recommendations that are more accurate than commonly used methods.

Measuring Voice Signal Enhancement

This technology measures the degree of enhancement made to a voice signal, reducing the need for human arbitrations and other various listening tests. Statistically, voice signals are “non-stationary,” changing over time. The more a signal becomes corrupted, however, the more stationary its distribution of values becomes. In this technology, the degree of reduction in the signal’s distribution indicates the degree of enhancement made to the signal. This invention quantifies the voice enhancement by comparing how stationary the distribution of values are between original and enhanced signals.

ALADDIN: Database Searching and Identifying Text US PATENT # 7,797,152 | US PATENT # 7,761,286 | US PATENT # 7,539,611

This technology is a combination of three inventions: two natural language database search methods and a method of identifying and highlighting text. The Tagger searches for transliterated terms (such as names) within large data sets using lexical, contextual, and morphological information. The Matcher is then applied to determine which candidate terms are known within the database and are therefore of likely increased interest to the reader. This knowledge-based system’s ability to work without relying on any one query language grants non-expert users access to an extensive collection of linguistic information and expertise. A typical application for this technology is name searching since names have unique linguistic and cultural complications and extracting names from data sources can be difficult.
