A method and apparatus is directed towards an advanced blade section for propellers that allow watercrafts to effectively travel in both sub-cavitating and super-cavitating modes. The manifold is connected to the pipe and enables the ionizable gas to flow into the ionization zone of the channel in concentric manner around the main axis. Contact lists that relate to different communications formats, such as voice communications, SMS messages, and email can be integrated into a single client view on the client device. The light module may be used for such processes as, for example, fluorescence, inspection and measurement, photopolymerzation, ionization, sterilization, debris removal, and other photochemical processes. a first rear attachment means removeably attachable to the wheel storage and transport frame; a first strap attached to the first rear attachment means; a first front attachment means attached to the first strap, and removeably attachable to the rotatable front panel; and a first tensioning means in communication with the first strap, and attached to the wheel storage and transport frame. The unique advantage of this invention is that it optimizes system power savings for display of low dynamic range images by dynamically controlling spatially adjustable backlighting.
