20110223816 | Combination hand-held multi-directional propulsion device and powered oar/paddle for rowboat, canoe, kayak, and the like - A multi-functional modular device comprises: a shaft; electric motor(s); battery(s); thrust producing fan(s); and blade(s) being removably attachable to the shaft for levering of a paddlesports boat. With the blade(s) attached to the shaft and the motor(s) off, the device is usable for manual levering, and with the motor(s) on, the fan blade thrust may selectively assist in levering to propel the paddlesports boat. Fan thrust may be usable in a direction opposite to a propulsive direction of levering to reduce work required per stroke, which reduces power per stroke, or may alternatively be usable in the same direction as propulsive levering to increase total propulsive power per stroke, which requires greater strength/work output by the rower/paddler. Various sized blades may be interchangeable therein to adjust the work output. Removing the blade(s) permits the fan to be statically submerged and clocked to propel the boat in a desired direction. | 09-15-2011 |

20100241026 | Portable suction device - An improved suction apparatus, which may be used by health care providers, emergency medical teams, or a corpsmen, to remove debris, fluid and other foreign matter from the airways and/or wounds of injured persons. The suction apparatus which includes: a venturi tube having a forward end, a rear end and an inlet, a valve located on the top rear end portion of the venturi tube, a body for housing at least one can of propellant or compressed gas, an airtight cap, and a trigger mechanism. The improved suction apparatus that forces the propellant passed the inlet of the venturi tube, wherein the inlet is located toward the distal end of the cap. | 09-23-2010 |

20130035010 | COMBINATION HAND-HELD MULTI-DIRECTIONAL PROPULSION DEVICE, AND POWERED OAR/PADDLE FOR ROWBOAT, CANOE, KAYAK, AND THE LIKE - A multi-functional modular device includes: a shaft; electric motor(s); propeller(s); battery(s); and paddle blade(s) being removably attachable to the shaft for levering of a boat. With the blade(s) attached to the shaft and motor(s) de-energized, the device is usable for manual levering, and with the motor(s) energized, propeller thrust selectively assists in levering to propel the boat. Propeller thrust in a direction opposite to a propulsive direction from levering reduces work required per stroke, reducing the total levering power per stroke. Alternatively, using the thrust in the same direction as propulsive levering increases total propulsive power per stroke, but requires greater strength/work output by the rower/paddler. Removing the blade permits the propeller and motor to be statically submerged and clocked for directional propulsion. A hinged kayak paddle embodiment is adapted for pure levering, and is convertible to a propulsion device by releasably attaching an electric pod motor to the blade(s). | 02-07-2013 |
