  • Patent number: 9366633
    Abstract: Multiple functional systems are integrated to configure a portable handheld decision-aid device for first responder medics. Fuzzy membership functions of “life” and “death” are used to determine the status of fallen people using remote measurements. EO/IR cameras can be used to detect and identify casualties in a mass injury situation, while also estimating body temperature. Using the temperature, along with the remote estimation of a second vital sign, the life membership proportion can be estimated from the ground truth by using a 2D projection of stable vital signs. The other fuzzy membership function, death, can be estimated by the presence or absence of peri-mortem and post-mortem molecules. These molecules are only released after death and provide a certain indication of death. Solid state UV laser resonance Raman backscattering from these molecules allows the device to analyze the molecules present in a plume around the casualty.

  • Patent number: 8185357
    Abstract: Changes, increase or decrease, in the body fluid are passively detected by using a single pixel, non-linear blind de-mixing procedure, which can be extended to general biomedical measurement and diagnosis instruments. More specifically, the single pixel, non-linear blind de-mixing procedure in applied on the hot spots of rheumatic arthritis or breast cancer detection problem using passive two-color infrared imaging, as well as to passively detect blockages in the body fluid circulatory system that might be of importance for coronary artery bypass surgery, diabetes and deep vein thrombosis. Other applications of the mentioned algorithm include a pair of cameras for video, a pair of antennas for cell phones, and in situ data gathering or imaging using multiple mode fiber-optical sensing, as well as selective amplification hearing aids through two-ear binaural processing for de-noise echo cancellation and signal classification.

  • Patent number: 7511655
    Abstract: A method and apparatus for determining three dimensional sub-voxel positions using synthetic aperture radar. The apparatus includes at least four non-coplanar, phase-coherent synthetic aperture radar (SAR) platforms comprising a plurality of phase-synchronized local oscillators cohered to a common reference clock, a first SAR platform of the SAR platforms operable to transmit a radar waveform, and the SAR platforms operable to receive scattered energy waveforms resulting from the radar waveform and operable to generate two-dimensional (2-D) SAR images based on the received scattered energy waveforms. The apparatus also includes a synchronizing processor operable to communicate with the SAR platforms and operable to synchronize a plurality of SAR transmission and receiving intervals for the SAR platforms.

  • Patent number: 4943556
    Abstract: A combination of optical interconnect technology with superconducting matal to form a superconducting neural network array. Superconducting material in a matrix has the superconducting current decreased in one filament of the matrix by interaction of the Cooper pairs with radiation controlled by a spatial light modulator. This decrease in current results in a switch of current, in a relative sense, to another filament in the matrix. This "switching" mechanism can be used in a digital or analog fashion in a superconducting computer application.

  • Patent number: 4538275
    Abstract: A synergistic quasi-free electron laser for generating infrared radiation. The laser includes a means for producing a volume of ionized gas plasma, a means for directing an electron beam through the gas plasma in a first direction, and a means for directing a laser pump beam into the gas plasma in a second direction opposite to the first direction to produce synergistic bunching of the electron beam and the ionized gas plasma. A portion of the laser pump beam is backscattered by the bunched electron beam and gas plasma to form an output beam having a frequency up-shifted from that of the laser pump beam. The frequency of the output beam may be tuned by changing the velocity of the electron beam.

  • Patent number: 4197510
    Abstract: A solenoid comprising several, discrete, coaxial, circular, superconducting coils provides a magnetic field which decreases radially to an absolute minimum intensity to focus the ions as they are accelerated to the end of the non-relativistic velocity range. As the ions are further accelerated to relativistic velocities, the magnetic field increases radially from the absolute minimum intensity to compensate for the relativistic increase in mass. The revolving ions are accelerated by repeated passage through an electric field which is established in radially-directed resonator horns. The accelerating structure and the associated electric field reinforce the focusing provided by the radially-increasing magnetic field.
