  • Publication number: 20240070875
    Abstract: A system includes a memory and a processing unit coupled to the memory. The processing unit is configured to receive first image data from a first image sensor exterior to a body, the first image data including data of an object; receive second image data from a second image sensor interior to the body, the second image data including data of the object; track the object moving across a body wall of the body based on the first and second image data to generate a tracking result to indicate a status of movement of the object across the body wall.

  • Patent number: 11746208
    Abstract: Methods for recycling thermoset polymers, particularly by changing them into dynamic networks with the use of an appropriate catalyst solution which transforms the thermoset polymer into a vitrimer-like composition. The methods include the step of swelling a crosslinked thermoset polymer in a solution including a catalyst, whereby the catalyst diffuses into the thermoset polymer, in particular into the thermoset network. Upon removal of the liquid portion of the solution, such as solvent, the catalyst facilitates the occurrence of exchange reactions at elevated temperatures, rendering the system a dynamic network. The vitrimerized composition having the thermoset polymer and catalyst is recyclable and processable and thus suitable for many end uses.
