    Intellectual Property Available to License

    US Patent 6,987,361
    • Field Emission Cathode Gating for RF Electron Guns and Planar Focusing Cathodes (IN-04-039)

    The phase and strength of a predefined harmonic field, such as the 3rd harmonic field, are adjusted relative to a fundamental field to cause a field emission cathode to emit electrons at predefined times for the generation of high-brightness electron beams. The emission time is gated responsive to the combined harmonic and fundamental fields and the response of the FE cathode to the combined fields. A planar focusing cathode includes a selected dielectric material, such as a ceramic material, to provide an electron beam emission surface. Metal surfaces are provided both radially around and behind the dielectric material to shape the electric fields that accelerate and guide the beam from the cathode surface.

    US Patent 7,525,010 B2
    • Process to Wash Polymers Contaminated with Polychlorinated Biphenyls (PCBS) (IN-06-067)

    A process of washing plastics contaminated with polychlorinated biphenyls (PCBs) is provided to reduce the concentration of the PCBs. A two-step process includes a first washing step using a selected washing solution or solvent, such as, a non-flammable solvent, and followed by a second step using thermal desorption. The two-step process enables reducing the concentration of PCBs in polymers, such as recovered from shredder residue, for example, to as low as 0.253 PPM. One of the preferred solvents is Perchloroethylene.

    Intellectual Property Available to License

    US Patent 9,103,904 B2
    • Interferometric Millimeter Wave and THz Wave Doppler Radar (IN-13-011)

    A mixerless high frequency interferometric Doppler radar system and methods has been invented, numerically validated and experimentally tested. A continuous wave source, phase modulator (e.g., a continuously oscillating reference mirror) and intensity detector are utilized. The intensity detector measures the intensity of the combined reflected Doppler signal and the modulated reference beam. Rigorous mathematics formulas have been developed to extract bot amplitude and phase from the measured intensity signal.

    Software in Matlab has been developed and used to extract such amplitude and phase information from the experimental data. Both amplitude and phase are calculated and the Doppler frequency signature of the object is determined.

    • Frequency and Amplitude Stabilization in MEMS and NEMS Oscillators (IN-15-101)

    This invention comprises a nonlinear micro- and nano-mechanical resonator that can maintain frequency of operation and amplitude of operation for a period of time after all external power has been removed from the device. Utilizing specific nonlinear dynamics of the micromechanical resonator, mechanical energy at low frequencies can be input and stored in higher frequencies modes, thus using the multiple degrees of freedom of the resonator to extend its energy storage capacity. Furthermore, the energy stored in multiple vibrational modes can be used to maintain the resonator oscillating for a fixed period of time, even without an external power supply.

    US Patent 9,966,966 B2
    • Nonlinearity Induced Synchronization Enhancement in Mechanical Oscillators (IN-15-079)

    An autonomous oscillator synchronizes to an external harmonic force only when the forcing frequency lies within a certain interval, known as the synchronization range, around the oscillator’s natural frequency. Under ordinary conditions, the width of the synchronization range decreases when the oscillation amplitude grows, which constrains synchronized motion of micro- and nano-mechanical resonators to narrow frequency and amplitude bounds.

    The present invention shows that nonlinearity in the oscillator can be exploited to manifest a régime where the synchronization range increases with an increasing oscillation amplitude. It also shows that nonlinearities in specific configurations of oscillator systems, as described herein, are the key determinants of the effect. This invention presents a new configuration and operation régime that enhances the synchronization of micro- and nano-mechanical oscillators by capitalizing on their intrinsic nonlinear dynamics.
