  • Patent number: 11890788
    Abstract: Methods of producing polymer-metal hybrid components that are bonded by C—O-M bonds at the interface using at least one of the hot pressing, rolling, and injection molding methods to create chemical bond formation conditions at the polymer and metal interface. When the thermal cycle and compressive pressure specified herein is combinationally created at the polymer and metal interfaced, strong C—O-M bonds forms at the interface and strongly bonds the metal and polymer together through the reaction carbonyl groups (C?O) in polymer and the metal surface. For polymers lacking enough carbonyl groups, new functional groups can be in-situ generation through introducing distributed air pockets at the polymer-metal interface for forming 3-dimensional distributed C—O-M bonds at the interface.

  • Publication number: 20240028900
    Abstract: Recent advances in model pruning have enabled sparsity-aware deep neural network accelerators that improve the energy efficiency and performance of inference tasks. SONA, a novel transform-domain neural network accelerator is introduced in which convolution operations are replaced by element-wise multiplications and weights are orthogonally structured to be sparse. SONA employs an output stationary dataflow coupled with an energy-efficient memory organization to reduce the overhead of sparse-orthogonal transform-domain kernels that are concurrently processed while maintaining full multiply-and-accumulate (MAC) array utilization without any conflicts. Weights in SONA are non-uniformly quantized with bit-sparse canonical-signed-digit (BS-CSD) representations to reduce multiplications to simpler additions.

  • Patent number: 11879744
    Abstract: Left turns are known to be one of the most dangerous driving maneuvers. An effective way to mitigate this safety risk is to install a left-turn enforcement—for example, a protected left-turn signal or all-way stop signs—at every turn that preserves a traffic phase exclusively for left turns. Although this protection scheme can significantly increase the driving safety, information on whether or not a road segment (e.g., intersection) has such a setting is not yet available to the public and navigation systems. This disclosure presents a system that exploits mobile crowdsensing and deep learning to classify the protection settings of left turns.

  • Publication number: 20240019249
    Abstract: Three-dimensional (3D) micro-scale shells are presented with selectively removed regions/openings and which can be used in sensors and actuators, including gyroscopes. Example shells consisting of a suspended ring-shaped resonator that is supported using multiple beams that are not in the plane of the ring and are attached to a support post can be formed. Shells with various sizes and geometries of selectively removed regions and openings allow the creation of micro electromechanical systems (MEMS) sensors and actuators with a wide range of engineered mechanical and electrical properties. These shells can be used to form stacked 3D structures for various types of MEMS sensor and actuator devices, such as resonant gyroscopes, with sense and drive electrodes that conform to the curved profile of the resonant shell using for gyroscopes. 3D shells formed from a starting parent substrate are released and separated from their parent substrate using a number of techniques.

  • Patent number: 11876147
    Abstract: An epitaxial growth process, referred to as metal-semiconductor junction assisted epitaxy, of ultrawide bandgap aluminum gallium nitride (AlGaN) is disclosed. The epitaxy of AlGaN is performed in metal-rich (e.g., Ga-rich) conditions using plasma-assisted molecular beam epitaxy. The excess Ga layer leads to the formation of a metal-semiconductor junction during the epitaxy of magnesium (Mg)-doped AlGaN, which pins the Fermi level away from the valence band at the growth front. The Fermi level position is decoupled from Mg-dopant incorporation; that is, the surface band bending allows the formation of a nearly n-type growth front despite p-type dopant incorporation. With controlled tuning of the Fermi level by an in-situ metal-semiconductor junction during epitaxy, efficient p-type conduction can be achieved for large bandgap AlGaN.

  • Patent number: 11874480
    Abstract: A plasmonic device incorporating a special hyperbolic metamaterial (HMM) metamaterial is used for plasmonic lithography, including ultraviolet (UV) lithography. It may be a Type II HMM (??<0 and ??>0) whose tangential component of the permittivity ?? is close to zero. Due to the high anisotropy of the Type II epsilon near zero (ENZ) HMM, only one plasmonic mode can propagate horizontally with low loss in a waveguide system with ENZ HMM as its core. In certain aspects, a Type II ENZ HMM comprises alternating layers of aluminum/aluminum oxide films and the associated unusual mode of light transmission is used to expose a photosensitive layer in a specially designed lithography system. Methods for making patterns of nanofeatures via such plasmonic lithography are also provided, including as a plasmonic roller device.
