20110050069SPARK PLUG - A spark plug includes a terminal for receiving an electrical charge, a firing electrode on a firing end of the spark plug, and a conductor electrically coupling the terminal and the firing electrode. The spark plug further includes a casing, an electrical insulator, and a ground electrode. The casing is at least partially formed from an electrically conductive material and is configured to be electrically coupled to a ground. The electrical insulator separates the conductor from the casing. The ground electrode is positioned proximate to the firing electrode, but separated from the firing electrode to allow a spark to jump between the firing and ground electrodes during operation of the spark plug. The ground electrode includes an extension coupled to the casing and projecting from the casing such that the firing electrode is closer to the ground electrode than the firing electrode is to the casing. There is substantially no air gap between the interior of the casing and the electrical insulator from the firing end of the spark plug.03-03-2011
20110226217ENGINE SPEED CONTROL SYSTEM - An engine includes a throttle assembly, a governor, and an actuator. The throttle assembly is designed to at least partially control a fuel flow rate of the engine. The governor is designed to sense a speed of the engine and at least partially control the throttle assembly as a function of the engine speed.

20110273022Method and Apparatus for Controlling a Hybrid Power System - The present invention provides a simplified method of controlling power among the various sources and loads in a power system. Power generating sources are each connected to a common DC bus through a converter. The converter selectively transfers energy to the DC bus at a maximum rate or at a reduced rate according to the level of the DC voltage present on the DC bus. At least one storage device is preferably connected to the common DC bus through a power regulator. The power regulator selectively transfers energy to or from the DC bus as a function of DC voltage level present on the DC bus. Further, an inverter may be provided to bidirectionally convert between the DC voltage and an AC voltage for connection to a customer load or the utility grid. Each power conversion device is independently controlled to provide a modular and simplified power control system.11-10-2011
