Abstract: The present invention disclose an Electrostatic doping (ED)-based graphene nanoribbon (GNR) tunneling field-effect transistor (TFET) with tri-gate design. This device uses hydrogen-passivated GNR heterojunction as a carrier path way and functions as a power switch providing a switching speed of ˜0.3 ps?1 an ION/IOFF ratio as high as 1014 with the on-state current in the order of 103 ?A/?m. This disclosed invention consists of two electrode, two electrode extensions, six metallic gate regions, and six dielectric regions.

Abstract: A method for virtual fencing including: obtaining first user status information pertaining to user location, user behavior, or both; generating a first notification upon detecting that the first user status information meets a triggering condition of a virtual fence, wherein the triggering condition comprises point of interest information, area of interest information, or both; and sending the first notification.

Abstract: A cover tape includes a polymer film substrate having first and second opposed major surfaces. A primer layer is disposed on the first major surface of the polymer film substrate. A static control layer is disposed on the primer layer, the static control layer comprising carbon nanotubes dispersed in a dielectric polymeric binder, wherein the static control layer has a thickness of from 0.1 to 2 microns. Adhesive strips are disposed on the static control layer adjacent opposite edges of the static control layer. Methods of making cover tapes according to the present disclosure, and component packages including them, are also disclosed.

Abstract: This utility model is a new interlocking structure for floor panel. The new interlocking structure for floor panel in accordance with the invention comprising floor panels; one panel edge having an upwardly curved flange, having at least one tooth, formed at it end and at least one hump and depression along its one top surface; the adjacent panel has a generally correspondingly shaped recess to receive the flange, the sectional configuration of tooth is trapezia. The floor panel made in this way, just because there is the interlocked gear shaped tongue on the vertical section of the tongue and groove connection. This interlocking increased the bearing capacity of floor panel from vertical acting force. And the abutting joint of panels is also improved obviously. It is useful and helpful to processing panel in vertical direction and laying precision of panel, as well as preventing the breakage of joint and distortion of floor panel.
