Abstract

In some conventional leaf blowers, air exhausted from the blower must travel through a bend before being directed through the output, reducing efficiency. In the present invention, the orientation of the blower system on the frame allows the output hose to be attached without the use of a bend thereby reducing air resistance and increasing efficiency. The present invention provides a leaf blower to be worn by a user and having a frame, a blower system, and an output tube. The blower system of the leaf blower includes an impeller having an axis of rotation and defining a working plane substantially perpendicular to the axis of rotation. The impeller and the tube axis of the output both lie on the working plane.

Abstract

A hybrid engine and battery generator and a method of operating the same. The generator is controlled to operate in at least three modes: a battery-only mode, a battery charging mode, and a boost mode. In the battery-only mode, the engine is off and an internal battery of the generator is used by an inverter to generate AC output. In the battery charging mode, the engine generates DC power, via an alternator and rectifier, which is used to charge the battery and to supply power to the inverter to generate AC output. In the boost mode, the battery and the engine generate DC power that is used by the inverter to generate an AC output with increased wattage, relative to the battery-only mode and battery charging mode. The generator automatically switches between the modes based on battery level and load demand.
