Abstract: An assembly for mobile electronic devices enhances audio by shaping the direction of emitted waves. Such a wave-shaping assembly is retractable so as to be flush or nearly flush with a surface of a mobile electronic device, and is extendable for playing audio to a listener more than a certain distance away from the mobile device. The wave-shaping assembly is suitable for voice, music, and other audible sound effects. The length and width of the extension of the wave-shaping assembly is variable, depending on the application and the industrial design of the mobile electronic device. The wave-shaping assembly is included either as a feature at time of manufacture, or as an added, optional attachment to a mobile electronic device.

Abstract: A pressurized washing apparatus includes an aerosol comprised of a solution of de-ionized or distilled water that is dispensed with pressure from a canister to lift away dirt or debris from surfaces of articles or items toward which it is directed. The solution of de-ionized or distilled water ensures that surfaces will air-dry without risk of leaving any mineral or calcium build-up, residue, or film behind. The aerosol is housed in a canister-based product that helps with vehicular upkeep so that the vehicle will be clean of spots, droppings, tree sap and other elements between car washes. The aerosol also enables users to wash hands and clean many other surfaces that require the removal of dirt using a cleaning aide or water under pressure where sources of water may not be available.
