  • Patent number: 12181340
    Abstract: The invention provides methods and apparatus comprising a multi-wavelength laser source that uses a single unfocused pulse of a low intensity but high power laser over a large sample area to collect Raman scattered collimated light, which is then Rayleigh filtered and focused using a singlet lens into a stacked fiber bundle connected to a customized spectrograph, which separates the individual spectra from the scattered wavelengths using a hybrid diffraction grating for collection onto spectra-specific sections of an array photodetector to measure spectral intensity and thereby identify one or more compounds in the sample.

  • Patent number: 12171885
    Abstract: One of the significant challenges to translation of intravenously administered nanomaterials has been complement-mediated infusion reactions which can be lethal. Slow infusions can reduce infusion reactions, but slow infusions are not always possible in applications like controlling bleeding following trauma. Nanocapsules based on polyurethane are introduced as candidates that do not substantially activate complement protein C5a and the PEGylation and functionalization of the nanocapsules with the GRGDS peptide to create a new class of hemostatic nanomaterials is disclosed. Advantageously, the nanocapsules substantially avoid complement-mediated infusion reactions, promote faster clotting than controls, maintain maximum clot firmness, and do not activate pro-inflammatory cytokines.

  • Patent number: 12161765
    Abstract: Bait and capture methods and compositions for removing bio-synthetic nano-particles from body fluids. Bio-synthetic nano-particles are baited with one-half of a bait and capture complex and lyophilized. The baited bio-synthetic nano-particle is reconstituted and administered to a subject for diagnostic or therapeutic purposes. To remove the bio-synthetic nano-particle from the body, the body fluid containing the baited bio-synthetic nano-article is contacted with the capture portion of the bait and capture complex. The body fluid from which the bio-synthetic nano-particles have been removed may be returned to the subject.

  • Patent number: 12037498
    Abstract: An energy-efficient method of controlling the composite microstructure and resulting thermoelectric (TE) properties of TE composite films. The TE composite films, which include a small amount of naturally occurring chitosan binder that is sufficient to hold TE particles together, are modified by applying uniaxial mechanical pressure at low temperatures for a short duration. The TE composite films have high electrical conductivity and low thermal conductivity, making them ideal for use into high-performance energy harvesting thermoelectric devices.

  • Patent number: 11921013
    Abstract: A one-dimensional (1D) and two-dimensional (2D) scan scheme for a tracking continuously scanning laser Doppler vibrometer (CSLDV) system to scan the whole surface of a rotating structure excited by a random force. A tracking CSLDV system tracks a rotating structure and sweep its laser spot on its surface. The measured response of the structure using the scan scheme of the tracking CSLDV system is considered as the response of the whole surface of the structure subject to random excitation. The measured response can be processed by operational modal analysis (OMA) methods (e.g., an improved lifting method, an improved demodulation method, an improved 2D demodulation method). Damped natural frequencies of the rotating structure are estimated from the fast Fourier transform of the measured response. Undamped full-field mode shapes are estimated by multiplying the measured response using sinusoids whose frequencies are estimated damped natural frequencies.

  • Patent number: 11921113
    Abstract: The present invention provides for excitable molecules positioned near metallic structures, wherein the metallic structures have a particles size from about 1 nm to 1000 nm and wherein the excitable molecules have fluorescence, phosphorescence or alpha-fluorescence emissions that are altered due to positioning near the metal structures. The emission spectra are distorted on either the blue or red edges in a range from 1 to 10 nm thereby changing the color of emissions. Further, the width of the emission spectrum is modified either by narrowing or broadening depending on the material of the metallic structures and type of excitable molecule.

  • Patent number: 11870034
    Abstract: Zinc electrolytic manganese dioxide (EMD) batteries including a high performing flexible chitosan-based gel electrolyte with poly-vinyl alcohol (PVA) and potassium hydroxide (KOH) additives were prepared. The Zn-EMD batteries were constructed using an optimized assembly technique employed to achieve good interfacial contact between the layers. Attaining energy densities between 150-250 Wh/kg (w.r.t cathode mass) is possible for these batteries, encouraging their use in wearable or flexible electronics. Using the chitosan-based gel electrolyte and limited voltage window testing, the prepared Zn-EMD alkaline batteries are among the best reported polymer-based alkaline electrolyte Zn rechargeable batteries.

  • Patent number: 11859716
    Abstract: A tidal current energy converter including an infinitely variable transmission (IVT) control system and a hybrid vertical axis wind (or water) turbine (VAWTs) apparatus. The hybrid VAWT apparatus includes a modified-Savonius (MS) rotor in the central region and a straight bladed H-type Darrieus rotor in the surrounding annular region. The IVT control system includes a nonlinear closed-loop control combined with an integral time-delay feedback control to adjust a speed ratio of the IVT. A speed ratio control for an IVT system involves a forward speed controller and/or a crank length controller for different speed ranges. The time-delay control is designed to reduce speed fluctuations of the output speed of an IVT with an accurate speed ratio. The speed ratio of an IVT with the disclosed control strategy can achieve an excellent tracking response for the desired constant output speed and reduce speed fluctuations of the output speed of an IVT by the time-delay feedback control.

  • Patent number: 11850441
    Abstract: Disclosed is an electromagnetic coil system for use during transcranial or transdermal stimulation procedures, in which an electrically conductive coil wraps around a magnetic core at an oblique wrapping angle to provide a more directed focal spot size at a given depth inside of, for example, a patient's body. In certain configurations, the electrically conductive coil may be adjustable with respect to the magnetic core, such that the wrapping angle of the electrically conductive coil may be modified to, in turn, adjust the focal spot size of the induced electric field generated by the system as may desired to concentrate the field at a particularly desired location.
