  • Publication number: 20220086416
    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: 11264877
    Abstract: An axial flux machine (AFM) includes a rotor rotatably disposed between a pair of fixed stators. The rotor and the stators are formed of tape-wound laminated cores of ferromagnetic material. In addition, the rotor includes multiple layers of angled magnets that circumscribe the rotor. Such configuration enables the axial flux machine to achieve a high airgap flux density while achieving a high saliency ratio and lowered cogging torque as compared to current generation AFMs.

  • Publication number: 20220041804
    Abstract: In various embodiments, the invention relates to poly(propylene fumarate) (PPF)-based star-shaped copolymers synthesized using a core-first approach that uses a multi-functional alcohols as an initiator, and Mg(BHT)2(THF)2 as catalyst for controlled ring opening copolymerization (ROCOP) of maleic anhydride (MAn) with propylene oxide (PO). In some embodiments, these star-PPF copolymers have lower viscosities than their linear analogs, allowing a decrease in DEF fraction in resin formulation, as well as the use of higher molecular weights. These star-shape PPF can be used to prepare PPF:DEF resins containing as much as 70% by weight of the multi-arm PPF star copolymers, and have a low complex viscosity of high Mn star PPF resin that affords rapid printing with a Mn nearly eight times larger than the largest linear PPF oligomer printed previously.

  • Patent number: 11233445
    Abstract: An acoustic noise mitigation system for an electric machine includes one or more suspension members. The suspension members may include arcuate members that are positioned between a machine housing and a stator. During operation of the electric machine, the electromagnetic force frequency that is generated by the stator relative to a rotating rotor is able to be absorbed by the suspension members. As a result, acoustic noise generated by the electric machine is reduced.

  • Patent number: 11225543
    Abstract: In one or more embodiments, the present invention provides a novel approach to the addition of plasticizers for softening TPUs, i.e., lowering the durometer and the melt viscosity. This approach involves incorporating bonded sulfonate groups with quaternary ammonium counterions into the TPU. In one or more embodiments of the present invention, the softening of TPU is achieved by incorporating an ionic diol, such as N,N-bis (2-hydroxyethyl)-2-aminoethane-sulfonic acid (BES), coupled with various bulky alkyl ammonium cations, during the chain extension step of the TPU synthesis. It is believed that that steric hindrance of the bulky quaternary ammonium groups weakens the dipole-dipole interactions of the sulfonate groups and/or lowers the crystallinity of the hard block, thereby creating additional free volume that softens the polymer and lowers the melt viscosity.

  • Patent number: 11221292
    Abstract: A method for locating human remains in a clandestine or undocumented burial includes providing a spectroscopy assembly including a spectroscopy probe with a distal end to a location that may include human remains, wherein the spectroscopy assembly is configured to identify whether a salt of a fatty acid is present based on overtone wavelengths of the salt of the fatty acid; inserting the distal end of the spectroscopy probe into a testing spot at the location that may include human remains; and analyzing, with the spectroscopy assembly and after the step of inserting, whether the salt of the fatty acid having the overtone wavelengths is present in the location that may include human remains. The step of analyzing may include near-infrared spectroscopy, and the overtone wavelengths may be characterized by an absorption band contour extending from about 1670 nm to about 1800 nm.

  • Patent number: 11207676
    Abstract: A lab-on-a-chip (LOC) for the biomimetic study of the multicellular interactions of bone cells includes a PDMS substrate and cap, which together form one or more wells that are fluidly coupled by tubes. The wells are configured to support various bone cells and related cellular support substrates therein, while the tubes allow conditioned medium (CM), including soluble signals, and various other co-factors to be communicated among the various wells. By controlling the configuration among and between various bone cells in the wells, the temporal and spatial limitations associated with traditional in vivo bone tissue models is removed. In addition, the LOC enables a particular research objective to be studied by allowing the user to configure the arrangement of the wells/tubes of the LOC, so as to control the manner in which bone cell soluble signals, bone cell contact, and bone cell matrix interaction interplay.
