Abstract: A method for collaboration using digital notes. A facilitator starts a session during a video conferencing with participants and can share a screen with the participants. The screen displays a code, a session ID, and a link. Participants join the session by scanning the code with a camera, entering the session ID, or accessing the link. During the session, the participants can create digital notes or scan physical notes to have them converted to digital notes. The facilitator then receives the digital notes sent from the participants during the session and moves the digital notes to a group on the facilitator's screen. Since the facilitator's screen is shared with the participants, any participant can view the digital notes in the group from all of the participants for collaboration as controlled by the facilitator.

Abstract: Embodiments include an X-ray cathode filament, filament system, process to manufacture the filament and process to use the filament, where the filament includes a planar substrate, such as of tungsten, having a top surface coated with a coating of carburized tungsten (e.g., W2C) and thoria (ThO2). A first electron beam is emitted from the coating through a thermionic effect at a first temperature, such as when the filament is heated to between 1700 and 1900 degrees Celsius by running an electrical current through the filament. At this temperature, a second electron beam may be caused by (1) a reaction that includes creating thorium (Th) in the coating, and (2) the thorium diffusing to uncoated surfaces of the substrate from which the second electron beam is emitted. The filament may also have slots forming a zipper shape, forming a square switchback shape, or forming a rectangular labyrinth shape to reduce the current required to heat the filament.
