Publication number: 20130190956Abstract: This invention provides a vehicle powered by a surface-mediated cell (SMC)-based power source, comprising a vehicle frame, at least a wheel supporting the frame or a propeller connected to the frame, a drive unit connected to the wheel or propeller, and a power source electrically connected to the drive unit, wherein the power source contains at least a surface-mediated cell. The vehicle can be a micro-EV (using the SMC for the stop-start function), HEV, plug-in HEV, all-electric vehicle, power-assisted bicycle, scooter, motorcycle, tricycle, automobile, wheelchair, fork lift, golf cart, specialty vehicle, bus, truck, train, rapid-transit vehicle, boat, or air vehicle. The ultra-high power density enables the SMC to provide pulsed power or increased current demands when the vehicle is accelerating or hill-climbing. The SMC also enables the power source to recuperate the braking energy when the vehicle decelerates, brakes, or simply moves down-hill.Type: ApplicationFiled: January 23, 2012Publication date: July 25, 2013Inventors: Aruna Zhamu, Guorong Chen, Xiqing Wang, Bor Z.

Patent number: 8480447Abstract: An improvement to a conventional surfboard includes an impeller and an electric motor contained primarily within the body of the surfboard, whereby performance of the surfboard is substantially unaffected by the presence of the impeller and the electric motor. The electric motor is operatively connected to the impeller for providing a forward thrust of the surfboard. The improvement to the conventional surfboard also includes a throttle for selective control of the electric motor for operating the impeller to provide a forward thrust of the surfboard, the throttle being configured for use by a surfer lying in a prone position on the smooth top surface of the body of the surfboard. An extent of the surfer's energy that otherwise would be expended during paddling can be preserved for riding waves by using the impeller to provide the forward thrust during paddling.Type: GrantFiled: July 26, 2011Date of Patent: July 9, 2013Assignee: Boomerboard, LLCInventor: Mike R. Railey

Publication number: 20130157526Abstract: Conventional unpowered surfboards enable riders to catch and ride waves towards a shoreline and experience the thrill and power of ocean waves. An electric powered surfboard has been developed to assist novice riders or riders who have suffered injuries or impairments which limit their ability to paddle are effectively prevented, or at least impaired from enjoying this activity. The surfboard comprises one or more propulsion systems which each comprise an electric motor, a drive shaft and a rotor. The rotor may be a propeller mounted in a fin of the board, or it may be an impellor in a water jet. The surfboard also comprises a power control system for controlling power to the propulsion system and comprises a speed controller and a battery as well as a cooling system for cooling the motor and speed controller. The surfboard may also comprise a monitoring system which comprises a power monitor and an output device for indicating the remaining capacity to the rider.Type: ApplicationFiled: November 16, 2012Publication date: June 20, 2013Inventor: Paul MARTIN

Patent number: 8439715Abstract: A support assembly for a trolling motor is disclosed whereby the trolling motor shaft is clamped into a separate threaded rack unit. A motor driving a gear engaged with the rack unit causes the trolling motor to be raised and lowered vertically. A spring is employed in the breakaway mounting assembly to allow the trolling motor propulsion unit to deflect upon striking an underwater obstacle, and thereby prevent damage to the trolling motor.Type: GrantFiled: January 4, 2011Date of Patent: May 14, 2013Inventor: Margaret Clark
