  • Patent number: 11325492
    Abstract: A method for the efficient placement of electric vehicle chargers in a target area couples vehicle dynamics and battery dynamics modeling with environmental factors to accurately incorporate the impact that the environment has on the range of the battery into the placement of the chargers by simulating trips of fleets of electric vehicles. The vehicles can be of various types, for example, motorcycles, cars, trucks or aircraft, and will each have their battery state of charge monitored as they traverse a simulated trip through the target area.

  • Patent number: 11305252
    Abstract: An ultra low density film and an ultra low density solid material are produced by the steps of providing a vessel, introducing two immiscible fluids into the vessel, adding nanocrystals to at least one of the two immiscible fluids, applying a shear force to the two immiscible fluids and the nanocrystals in a manner that causes the nanocrystals to self-assemble and form colloidosomes. The colloidosomes amass and evaporation of the two fluids produces dried colloidosomes. The ultra low density self-assembled colloidosomes are hollow self-assembled colloidosomes, which are formed into the ultra-low density film and the ultra-low density solid.

  • Publication number: 20220081660
    Abstract: A perfusion bioreactor system has an inner chamber and scaffold with matching porosities to equalize fluid flow through a bioreactor. The scaffold can be fabricated using additive manufacturing or other fabrication techniques to match the geometrical shape of a defect, such as a facial bone anomaly. The inner chamber is fabricated in a similar manner and has an inner cavity matching the shape of the scaffold to create a unified structure when assembled together with the scaffold. By matching the shapes of the scaffold and inner chamber, free space is eliminated within the interior volume of the bioreactor. Stem cells can be flowed through the bioreactor and attached to the scaffold, which are then cultured to grow a tissue graft.
