  • Patent number: 10992922
    Abstract: An optical imaging system to image a target object includes a light source configured to emit one or more light rays to illuminate the target object and an image detector configured to capture a three-dimensional topography image of the target object when emitted light is emitted from the target object in response to being illuminated by the light rays emitted by the light source. A fluorescence image detector captures a fluorescence image of the target object when fluorescence is emitted from the target object in response illumination by light rays emitted by the light source. A controller instructs the image detector to capture the 3D topography image and the fluorescence image detector to detect the fluorescence image of the target object intraoperatively and to co-register and simultaneously display intraoperatively the co-registered topography and fluorescence information to the user via a display.

  • Patent number: 10975198
    Abstract: In various embodiments, the present invention is directed to terpolymers of carbon monoxide (CO), olefins (alkenes), and epoxides, as well as related methods and catalysts for their making and use. These terpolymer chains are comprised of ketone repeat units, ester repeat units, and ether repeat units. The additional presence of the ester repeat units and ether repeat units have the effect of lowering terpolymer melt temperature relative to that of similar polyketone, thus separating melt temperature from decomposition temperature, making it suitable for melt processing. In a single reaction mixture, the same metal catalyst that polymerizes CO with olefins also incorporates epoxide monomers into the terpolymer in the form of ester or ester and ether linkages. As a part of the terpolymer chain, the ester groups can undergo hydrolysis, rendering these terpolymer compositions hydrolytically degradable.

  • Patent number: 10968303
    Abstract: In various embodiments, the present invention provides a strong, synthetic elastomer materials (and related methods for making same) with mechanical properties that are controlled by the stereochemically-defined double bonds within their backbone, yet have physical properties that are derived from monomer selection and defined, modifiable, chain end groups. The use of the organocatalyzed, stereospecific addition of thiols to activated alkynes, affords isolated high molar mass materials (>100 kDa) via step-growth polymerization with high levels of cis- or trans-double bond content. Furthermore, in various aspects of the present invention, it has been found that changing the monomer composition and chain end groups provides additional control over the materials' physical properties to provide more efficient compounding with polar additives. Using this approach to elastomer synthesis, further end group modification and toughening through various vulcanization strategies are also possible.

  • Publication number: 20210093417
    Abstract: An imaging and display system for guiding medical interventions includes a wearable display, such as a goggle display, for viewing by a user. The display presents a composite, or combined image that includes pre-operative surgical navigation images, intraoperative images, and in-vivo microscopy images or sensing data. The pre-operative images are acquired from scanners, such as MRI and CT scanners, while the intra-operative images are acquired in real-time from a camera system carried by the goggle display for imaging the patient being treated so as to acquire intraoperative images, such as fluorescence images. A probe, such as a microscopy probe or a sensing probe, is used to acquire in-vivo imaging/sensing data from the patient. Additionally, the intra-operative and in-vivo images are acquired using tracking and registration techniques to align them with the pre-operative image and the patient to form a composite image for display by the goggle display.

  • Patent number: 10954276
    Abstract: The present invention is directed to enzyme based methods for removing water insoluble non-starch polysaccharides (NSPs) and/or water soluble or insoluble oligosaccharides from soy products without significantly damaging the proteins contained therein This removal is facilitated by the enzymatic hydrolysis of poly- and oligomeric carbohydrates into monosaccharides and other water soluble sugars. The present invention provides for the production of three streams of useful materials. The first is an enriched protein material comparable to the known SPCs but without significant quantities of undigestible oligosaccharides and polysaccharides. The second is an SPI made from the soluble protein in the hydrolysate which is valuable for high-quality feed, food and industrial uses. The third is the soluble saccharides and hydrolyzed carbohydrates (releasing sugars) that can be converted by fermentation to various valuable bioproducts.

  • Publication number: 20210028737
    Abstract: A control system for a switched reluctance machine includes a capacitor and an inverter connected to the capacitor, wherein the inverter generates current signals and a ripple current returned to the capacitor. A switched reluctance machine (SRM) receives the current signals and generates a position signal. A controller receives the ripple current, current signal values of the current signals, and the position signal and generates desired reference current waveforms received by the inverter to adjust the current signals received by the SRM.

  • Publication number: 20210002421
    Abstract: In one or more embodiments, the present invention is directed to a novel method for synthesizing Mg(BHT)2(THF)2 catalyst, which has several advantages over previous methods. Dry toluene or pentane are not required for synthesizing the catalyst, and the reaction is done in a bulk solution of BHT and THF. Further, because the Mg(BHT)2(THF)2 is made in a one-step (“one-pot”) synthesis, the time required for synthesizing and drying the catalyst is reduced. Using the new method of the present invention, the Mg(BHT)2(THF)2 is pure after removing excess THF, thereby eliminating the need for washes and recrystallization.

  • Patent number: 10875015
    Abstract: Methods for making porous materials having metal alloy nanoparticles formed therein are described herein. By preparing a porous material and delivering the precursor solutions under vacuum, the metal precursors can be uniformly embedded within the pores of the porous material. Once absorption is complete, the porous material can be heated in the presence of one or more functional gases to reduce the metal precursors to metal alloy nanoparticles, and embed the metal alloy nanoparticles inside of the pores. As such, the metal alloy nanoparticles can be formed within the pores, while avoiding surface wetting and absorption problems which can occur with small pores.
