Abstract: A system is provided for generating plasma within narrow diameter tubes, e.g., tubes with an inner diameter of less than 1 millimeter. The system may comprise the tube, a nozzle connected to at least one end of the tube configured to supply a gas into the interior of the tube at atmospheric pressure, at least one ring-shaped anode electrode and configured to surround an outer surface of the tube, at least one ring-shaped cathode electrode spaced apart from the anode electrode along the longitudinal axis and configured to surround the outer surface of the tube, and a voltage source connected to the at least one anode electrode. When activated, the system is configured to generate an electric field between the electrodes which ignites a plasma within the gas in the interior of the tube.

Abstract: Apparatus for plasma synthesis of graphitic products including graphene, comprising: a plasma nozzle coupled to a reaction chamber; means for supplying a process gas to the plasma nozzle, the process gas comprising a carbon-containing species; and means for supplying radio frequency radiation to the process gas within the plasma nozzle, so as to produce a plasma within the nozzle in use, and thereby cause cracking of the carbon-containing species; wherein the plasma nozzle is arranged such that an afterglow of the plasma extends into the reaction chamber, the cracked carbon-containing species also passes into the reaction chamber, and the cracked carbon-containing species recombines within the afterglow, so as to form graphitic products including graphene. A method of plasma-synthesising graphitic products including graphene is also provided.

Abstract: A compact portable video recording device that records when activated. A casing module contains an embedded camera that is connected to a weighted foundational support by means of a variable hinge which can be adjusted in an upward or downward position to adjust the viewing angle. The variable hinge allows the casing module to be aimed in any direction and maintain its position. At the time of activation of the portable video recording device connects using wireless communication. The video data is recorded to a removable memory and may be viewed “live” externally using wireless communication and interfacing with an external device or smart device. Adjusting the portable video recording device to a folded or “off position” stops the local video recording, ends the wireless communications and places the device in an energy conservation state.

Abstract: A computer system for creating and displaying a presentation is disclosed. In various embodiments, the computer system receives a request to generate one or more slides and to associate the one or more slides with a particular background. The system then displays a preview of the one or more slides and the associated particular background in a preview area. The system, in one or more embodiments, is configured to display, during the presentation, the one or more slides overlaid on the one or more backgrounds. In a particular embodiment, the computer system is configured to display multiple slides on a single background during the presentation.

Abstract: A computer system for creating and displaying a presentation is disclosed. The computer system may receive a request to generate multiple presentation slides and to associate the slides with a particular background. Later, during a presentation, the system simultaneously displays the slides against the one or more backgrounds within a slide display area. The system may be configured to allow one or more users, during the presentation, to: (1) selectively annotate the slides; (2) save the annotations to memory for future use; (3) independently rotate and/or resize one or more of the first and second slides; (4) remove the first slide from the slide display area independently of the second slide; and/or (5) add one or more additional slides to the slide display area.

Abstract: A system and method that allows a user to interactively display a presentation to one or more viewers. The presentation system allows the presentation to be displayed on an interactive display while one or more mobile computing devices assigned to each viewer connects to the presentation system so that the viewer can view the presentation and also receive one or more slides from the presentation in real-time while the slide presentation is being presented. The received slides may be electronically editable versions of the slides being displayed or electronically editable versions of slides that contain subject matter related to the subject matter of the slides being displayed. The viewers can edit the electronically editable versions of the slides and send the edited versions back to the user during the presentation. The user may then optionally display one or more of the edited slides as part of the presentation.

Abstract: A hanger having a front plate attached through a plate junction to a back plate. At the rear of back plate are lower pins that extend outward from back plate. Back plate has slots that hold lower pins. A hinge pin is provided that traverses the upper portion of plate junction and fits into a slot that traverses the top of back plate horizontally. Hinge pin is bent backward and downward at right angles to ensure vertical portions of hinge pin do not create a binding condition between the fabric-covered wall or furniture and the back plate. Vertical portions of hinge pin are used to initially pin the hanger into the applicable fabric-covered wall or furniture. Once the tips of hinge pin are inserted into the fabric of the fabric-covered wall or furniture, the rest of the hanger will rotate freely on the horizontal axis of hinge pin allowing the lower pins to penetrate the fabric exterior surface and the inner core material at an angle slightly less than 90 degrees.

Abstract: A hanger having a fixed pin assembly and a hinged pin assembly. Left and right vertical portions of fixed pin assembly are used to pin the hanger into the inner core of the applicable fabric-covered wall or furniture. Once the left and right vertical portions are inserted, the hinged pin assembly will rotate freely allowing the left and right lower angled portion to penetrate the fabric exterior surface and the inner core. At the central portion of the hinged pin assembly is a prong.
