  • Publication number: 20200058456
    Abstract: Methods for assembling low-profile, singulated keyboards by prefabricating key assemblies onto a chassis strip that is divided into individual key assemblies only after the substrate is affixed to a feature plate of keyboard. For example, a row of key assemblies is fabricated onto a chassis strip. The row corresponds to a partial or complete row of keys of the keyboard. The chassis strip is thereafter affixed to a feature plate in a specific location, thereby aligning each prefabricated key assembly to a precise location on the feature plate. While connected, each prefabricated key assembly is independently affixed to the feature plate. Thereafter, interconnecting portions of the chassis strip between the prefabricated key assemblies are removed, thereby singulating each key assembly.

  • Publication number: 20200040519
    Abstract: Disclosed in the present disclosure are a self-fused graphene fiber and a method of preparing the same. Dried graphene oxide fibers are soaked in a solvent to swell and then the fibers are pulled out and coalesced. After being dried, the graphene oxide fibers are fused together, and then are further reduced to obtain a self-fused graphene fiber. The entire self-fusion process can be quickly finished within one minute without adding any additional binder. The operation is simple and time-saving. The process is environmentally friendly; the bond strength is high, and the excellent properties such as outstanding mechanical strength and electrical conductivity of the graphene fibers themselves can be maintained. The present disclosure has great research and application value for further preparation of two-dimensional graphene fabrics or three-dimensional network bulks with excellent performance.

    Abstract: A node device in a blockchain receives an asset issuance transaction from an asset issuer, where the asset issuance transaction comprises a commitment value and a proof for performing a zero-knowledge proof with respect to the commitment value, and where the commitment value is calculated by inputting at least an asset type of a target asset object issued by the asset issuer to a commitment function. The zero-knowledge proof with respect to the commitment value based on the proof is initiated. It is determined that the asset type of the target asset object is in a set of legal asset types allowed to be issued by the asset issuer. In response to determining that the asset type of the target asset object is in the set of legal asset types allowed to be issued by the asset issuer, the commitment value to the blockchain is issued for storage.
