    Over the Horizon Scintillation Method (OTH) and Software
    Method and Software to Improve Radar
    UAF Inventors Bill Bristow and Tim Theurer have developed a method to improve the resolution of radar systems by as much as a factor of 10. 
     
    The inventors came up with the improvement while working on the Super Dual Auroral Radar Network, known as SuperDARN.  SuperDarn is a collection of high-frequency (HF) phased array radars used primarily to measure space weather.  SuperDARN maps the flow of charged particles in the upper atmosphere, but the radar also observes targets such as planes that are thousands of kilometers away from the radar and beyond the visible horizon.
     
    The radar system is able to observe vehicles that are thousands of kilometers away, but the signals received from these over-the-horizon (OTH) targets propagate through the upper atmosphere under far from ideal conditions.  In the case of these targets, the achieved resolution of the radar is greatly reduced by environmental effects on the signals as they propagate through the upper atmosphere.
     
    The method improves the resolution of radar by independently correcting for the environmental effects on the signals received at each antenna.  The method approximates the signals that would exist under ideal conditions and updates them over time to track the random fluctuations observed.  Through experiments with SuperDARN, The team observed a reduction of the uncertainty in determining the direction of a target by as much as a factor of 10. 
     
    While the inventors have developed the environmental distortion correction software with HF OTH systems such as SuperDARN in mind, the techniques and algorithm could be used with any system that suffers from an equivalent type of wavefront distortion.

  • Path-seq for NIC.png
    Next Gen Sequencing Method
    A New method to detect pathogens faster and cheaper
    Next generation sequencing (NGS) technology is the future of clinical molecular diagnostics.  However, looking for a pathogen in a clinical specimen is like searching for a needle in a haystack.
     
    Dr. Jack Chen at UAF has developed a new method, named “Preferential Amplification of Pathogenic Sequences (PATHseq)” that can be used to greatly enrich pathogenic sequences in clinical samples.
     
    The technology significantly reduces the cost per clinical sample to less than 10% of current commercial kits, while providing detection and identification of multiple viral genotyping and viral loads.  
     
    The "PATHseq" technology is covered by pending US patent (Application No. PCT/US14/68644).

  • Ground Squirrel
    Therapeutic Hibernation
    Pharmaceutical Adjunct and Method
    Approximately 795,000 people suffer a stroke each year, leading to insufficient blood flow to the brain to meet metabolic demand.  This situation is known as cerebral ischemia, and if blood demand is not restored in short period of time, it could ultimately lead to the death of brain tissue.

    Therapeutic hibernation is a medical treatment that lowers a patient's body temperature in order to help reduce the risk of tissue injury from lack of blood flow.  It is the only neuroprotective treatment found in clinical trials  to improve outcomes following cerebral ischemia.  Even though therapeutic hibernation is becoming the standard of care for comatose patients after cardiac arrest.  It has proven difficult to implement in stroke patients due to thermoregulatory defenses & shivering in conscious patients.
     
    Based on their work with hibernating mammals, UAF inventors have invented a method and pharmaceutical adjunct to eliminate these side effects.

    Piano Light
    For giving an illuminating performance

    Gary Toth has invented a new piano light.  The light assembly enables a pianist to easily see the keys in any lighting situation without interfering with their ability to play the piano or keyboard.

     

    The assembly contains an LED light strip that is suspended above and spans the entire keyboard. The light is user-controlled by a dimmer mounted at either side of the piano powered directly from an AC outlet or a rechargeable battery.

     

    The piano light has been used for live concerts at the University of Alaska Fairbanks with very enthusiastic performance reports.

    Signal Processing Software and Patents
    Software to digitally process a variety of signals.

     

     
    UAF Patent # 8,554,816  describes a filter which cleans digital signals and resolves the cocktail party effect. This technology focuses a listener’s attention on a single sound among a mixture of background noises, while ignoring other conversations.
     
    T racking a moving signal by passive methods has been difficult due to the Doppler shift that is introduced into the observations of each sensor. The system and method described in  patent #7,710,827  overcomes the complications of Doppler shifting in signal source tracking.  
     
    Using a passive sensor array to determine the position of a signal source has proven difficult, and many techniques are only designed for application with sensor arrays of specific, symmetrical geometries.  Patent #7,746,225  protects a fast method of determining the location of a signal source.

    Timesheet Planner
    Software for University Supervisors to Plan Employee Time and Forecast Expenditures
    University faculty and staff spend hours each week tracking their time spent working on individual funding.   UAF inventors have developed lean, web-based software that makes time tracking and financial planning easy.
     
    The tool is interoperable with Ellucian’s Banner system and Microsoft Excel, which means it can work with many university and private-sector billing systems. 
     

  • Eyjafjallajokull Volcano.jpg
    Rapid Response Volcanic Ash Detector

    Dr. Cathy Cahill has invented an integrated system for warning an aircraft of potentially hazardous conentrations of volcanic ash or other large ambient aersols.  
     
    The system is designed to function on-board the aircraft and warn the crew of increasing concentrations of volcanic ash so they can exit the encountered volcanic ash plume prior to the aircraft encountering the high concentrations of ash in the heart of the plume.

  • Livengood - Wiltse - Fractal Dimensions of Mapped Faults.png
    Fractal Software for Mineral Exploration
    Add Date here
    Dr. Milton Wiltse and his colleagues at University of Alaska have developed software tools that are useful in guiding mineral exploration efforts.
     
    The  tools automate the process of extracting various measures of the spatial association between mineral occurrences and geologic features, measures of geologic complexity, and obscure alignment trends among known deposits in areas of interest.
