Abstract: Systems and methods for edge assisted real-time object detection for mobile augmented reality are provided. The system employs a low latency offloading process, decouples the rendering pipeline from the offloading pipeline, and uses a fast object tracking method to maintain detection accuracy. The system can operate on a mobile device, such as an AR device, and dynamically offloads computationally-intensive object detection functions to an edge cloud device using an adaptive offloading process. The system also includes dynamic RoI encoding and motion vector-based object tracking processes that operate in a tracking and rendering pipeline executing on the AR device.

Abstract: A method for forming a carbon fiber-reinforced polymer matrix composite by distributing carbon fibers or nanotubes into a molten polymer phase comprising one or more molten polymers; and applying a succession of shear strain events to the molten polymer phase so that the molten polymer phase breaks the carbon fibers successively with each event, producing reactive edges on the broken carbon fibers that react with and cross-link the one or more polymers. The composite shows improvements in mechanical properties, such as stiffness, strength and impact energy absorption.

Abstract: A microneedle assembly and a method of fabrication the assembly are provided. The microneedle assembly includes an array of microneedles attached to a base. Each of the microneedles comprise a tip, a needle shaft and a plurality of cantilevered barbs protruding outwardly from the needle shaft, where a plurality of the microneedles include two or more of the cantilevered barbs arranged in a series of concentric rings along the needle shaft of each of the plurality of microneedles. The microneedle assembly may be fabricated using a 3D printing technique, where one or more cantilevered layers are formed by exposing a photocurable liquid resin including monomer material to a light source to create initially horizontal, cantilevered barbs having a crosslinking gradient, and rinsing to remove an amount of un-crosslinked monomers from the cantilevered layers to induce curvature in the cantilevered barbs extending towards a direction of the lower crosslinking.

Abstract: The invention provides UV-sensitive monomers, comprising a cyclopropenone-containing group, which acts as a masked dibenzocyclooctyne (DBCO)/dibenzoazocyclooctyne (DIBAC) group. The monomers of the invention can be polymerized for example via reversible addition fragmentation chain transfer (RAFT) polymerization techniques to yield a polymer comprising the masked DBCO/DIBAC group. In certain embodiments, the DBCO/DIBAC group can be unmasked under controlled conditions, allowing conjugation of small molecules and/or macromolecules to the polymer through highly selective and efficient strain-promoted azide alkyne click chemistry (SPAAC).
