  • Publication number: 20260073584
    Abstract: This application relates to the field of display technologies, and provides a surface composition method, an electronic device, and a storage medium. The method is applied to an electronic device, specifically including: obtaining to-be-displayed data; generating a surface in a UBWC format corresponding to the to-be-displayed data when the to-be-displayed data satisfies a first condition, where the first condition is displaying the surface of the to-be-displayed data after transform; performing a transform operation on the surface in the UBWC format, to obtain a transformed surface in the UBWC format; and performing surface composition on the transformed surface in the UBWC format.

  • Patent number: 12358215
    Abstract: Binders and methods of binder jetting are provided based on the use of branched polymer binders. The applicants have found that, even more so than the molecular weight, the ability to achieve higher maximum printable concentrations leads to higher densities and improved structural properties of the manufactured articles. The methods can be used for a variety of articles from metal parts to structural ceramics, to tablets and other oral dosage forms. The branched chain polymers can include a short-chain branched polymer; a long-chained branched polymer; a hyper-branched polymer, a cyclic polymer; a comb-type polymer; a 3-arm star type polymer, a 4-arm star type polymer, a dendritic polymer, and a combination thereof. The branched-chain polymer can include various polymers such as polyvinylpyrrolidone, poly(vinyl alcohol), or poly(acrylic acid).

  • Patent number: 9620638
    Abstract: A tri-gate laterally-diffused metal oxide semiconductor (LDMOS), including a substrate, a P-type semiconductor region, a P-type contact region, an N-type source region, a gate dielectric layer, an N-type drift region, a first isolation dielectric layer, an N-type drain region, and a second isolation dielectric layer. The P-type semiconductor region is disposed on one end of an upper surface of the substrate, and the N-type drift region is disposed on another end of the upper surface. The P-type semiconductor region contacts with the N-type drift region. The P-type contact region and the N-type source region are disposed on one side of the P-type semiconductor region which is away from the N-type drift region, and compared with the P-type contact region, the N-type source region is in the vicinity of the N-type drift region.

  • Patent number: 9469648
    Abstract: Provided are methods for reversing the effects of agents used for muscular immobilization and/or loss of consciousness and/or loss of pain perception. The method comprises administering a composition comprising acyclic CB[n]-type compounds to an individual in need of reversal of the effects of neuromuscular blocking agents and/or anesthetic agents such that the effects of the agent(s) are partially fully reversed.
