20110201238 | Electric Powered Surfboard Propulsion and Control Systems - Practical electric-powered propulsion systems, associated operator-control systems, and modification methods enable conventional surfboards (and similar small watercraft) to be converted for water-jet propulsion. Wireless controls are integrated with wearable marine accessories such as modified neoprene or fabric gloves, armbands, wristbands, hand straps, or gauntlets. Safely immersible, wet-swappable high-power battery packs facilitate extended use of electric propulsion in surf. Compact integrated electronic control units incorporate motor controllers, wireless receivers, and control logic. On-board power, propulsion, and control components are positioned and installed to avoid disrupting the shape of the watercraft body so as to minimize added hydrodynamic drag and perceived differences from a traditional unpowered version of the watercraft in appearance, balance, or performance. Components are designed to facilitate efficient installation using construction techniques already in widespread use among manufacturers and customizers of the analogous unpowered watercraft. | 08-18-2011 |
