Abstract: A device operative having a rotating cleaning tip for cleaning a narrow channel, such as an ear canal. In one embodiment, the tip is coupled to a handle with a motor that rotates the tip. The rotating tip has a plurality of strips that bow outwardly, scraping debris from the walls without debris accumulating and impacting along a channel wall. The bowing strips provide entry slits to capture debris into the tip, the strips closing after capture, removing debris when the tip withdraws from the channel. The device has a safety ring disposed around the tip, the safety ring operative for limiting penetration into a narrow canal when cleaning.

Abstract: A method and system to capture kinetic energy of the sea waves and convert it to electrical power is presented. The hydrodynamic power of the waves is converted to mechanical power after impacting and moving a special panel. The mechanical power is converted into a controlled-cycle hydraulic power to activate a hydraulic motor, which in turn activates an electrical generator. Electrical power is then measured, controlled and distributed to a power grid or end users.
