Abstract: Embodiments include a spring loaded piston in an internal combustion engine. In certain embodiments, the internal combustion engine may include a two stroke, one cylinder piston engine having first springs connecting between a piston and a cylinder head and second springs connecting between the piston and the base of the piston cylinder. The first springs are relatively compressed when the crankshaft is at top dead center while the second springs are relatively relaxed when the crankshaft is at top dead center and vice versa at when the crankshaft is at bottom dead center. During the power/intake stroke, some of the fuel's energy is delivered to the crankshaft and some is used to compress the second springs. The stored energy in the second springs is delivered to the crankshaft during the exhaust/compression stroke while the second springs return to their relatively relaxed condition and vice versa for the first springs.

Abstract: A liquid dispensing system includes a first container configured to house a first liquid, a plurality of nozzles, and a flow path connecting the first container to the plurality of nozzles. A second container configured to house a second liquid and having an electric valve mechanism which is disposed in the flow path downstream from the first container and upstream from the plurality of nozzles. A pump is in fluid communication with the first container and the plurality of nozzles and the pump is configured to force the first liquid and the second liquid through the flow path to be emitted by the plurality of spray nozzles. The liquid dispensing system further includes a controller that controls the electric valve mechanism and opens it to an open position to disperse the second liquid from the second container into the flow path upon an receiving a signal from a user.

Abstract: Embodiments include a vacuum head portion and a combined suction and blowing mechanism configured to agitate and remove debris. A set of powered fans provide an external pressured air source to provide pressured air for the blowing mechanism. The vacuum head portion may include blowing and suction nozzles arranged with the blowing nozzles flanking the suction nozzles. The set of powered fans may be driven an electric motor or via air turbines disposed in an air stream of the suction nozzles. The blowing nozzles may be in parallel rows adjacent to the suction nozzles. The blowing mechanism may be operated to act as a suction device by reversing the rotational direction of the set of powered fans via a switching mechanism to create a negative pressure or suction to assist the suction nozzles. The vacuum head portion may be formed as a removable detachment to the vacuum cleaner.

Abstract: Embodiments include a method and apparatus for preventing damage to the paintwork of vehicles caused by spillage of fluids or fuel when refueling. The method includes installing the apparatus into a fuel tank inlet of a vehicle and extending the apparatus from the fuel tank inlet. The apparatus includes a container configured to capture any spillage via a funneling trough extending from the fuel tank inlet to the container. The method further includes raising the apparatus above the fuel tank inlet to return the captured spillage to the fuel tank inlet via the trough. The method also includes retracting and inserting the apparatus into the fuel tank inlet ready for reuse during the next refueling of the vehicle.

Abstract: A camera viewing system and method includes a first array of cameras distributed atop a carrier to record or stream video content about a radial view of the carrier. A second array of cameras distributed about a first side of the carrier records or streams video content from a front and back first side view of the carrier. A third array of cameras distributed about a second side of the carrier records or streams video content from a front and back second side view of the carrier. A router routes the recorded and streamed video content to the carrier, and a transmitter transmits the recorded and streamed video content to a satellite for routing to a receiver for subsequent display away from the carrier. A plurality of displays receives camera manipulation instructions from multiple parties and displays associated results, via respective GUIs.
