  • Patent number: 12284817
    Abstract: Heterostructure and double-heterostructure trench-gate devices, in which the substrate and/or the body are constructed of a narrower-bandgap semiconductor material than the uppermost portion of the drift region. Fabrication most preferably uses a process where gate dielectric anneal is performed after all other high-temperature steps have already been done.

  • Publication number: 20250123614
    Abstract: In one example in accordance with the present disclosure, an electronic device is described. An example electronic device includes a processor and memory storing executable instructions that when executed cause the processor to receive an image of a polymer melt pool captured during crystallization of the polymer melt pool. The instructions also cause the processor to measure brightness of the polymer melt pool in the captured image. The instructions further cause the processor to determine crystallization information of the polymer melt pool based on the measured brightness of the polymer melt pool.

  • Publication number: 20250094674
    Abstract: Examples of methods are described herein. In some examples, a method includes generating, using a compensation machine learning model after training, a compensated model based on a three-dimensional (3D) object model. In some examples, the compensation machine learning model is trained by generating candidate compensation plans and evaluating, using a deformation machine learning model, the candidate compensation plans. In some examples, the method includes adjusting the 3D object model based on the compensated model to produce an adjusted model.

  • Publication number: 20240430621
    Abstract: A vibration damping loudspeaker includes a sound-generating unit, a magnetic member, an assembly-auxiliary frame and dampers. Aligning units of the assembly-auxiliary frame are coupled to positioning units of the sound-generating unit. The dampers are symmetrically disposed between the magnetic member and the assembly-auxiliary frame. The sound-generating unit and the magnetic member can be quickly and easily mounted in place because of the assembly-auxiliary frame to not only enhance the production yield of the vibration damping loudspeaker but also allow the dampers to function as a buffer between the sound-generating unit and the magnetic member, so as to achieve vibration damping and vibration isolation during the operation of the vibration damping loudspeaker to spare users the discomfort they will otherwise experience for using electronic devices.
