| 20090287391 | Engine Fuel Control System - A fuel control system is provided. The fuel control system includes an electronic control system coupled to a pair of control valves for blending pipeline fuel with waste fuel at a blend ratio for controlling fuel flow to an internal combustion engine. The fuel control system can estimate energy content of the fuel mixture to compensate the blend ratio. The fuel control system can use engine operational parameters to compensate the blend ratio. Typically, the system will use the operational parameter of output power or exhaust emissions to compensate the blend ratio. Further, the fuel control system can prioritize variation from the blend ratio or variation from a desired power output when the blend ratio cannot generate the desired power output. The fuel control system can also be equipped with engine speed/load controls, misfire, ignition timing and knock detection capabilities. | 11-19-2009 |

| 20090159218 | Roller Blind and Assembly Comprising a Roller Blind of This Type and Double Glazing Unit - The invention relates to a roller blind having at least four layers. The outer layers form one sheet and the inner layers form one sheet. A cylindrical body is provided in the inner sheet. The outer sheet has a bending stiffness which is such that, at least at the location of the cylindrical body between the layers of the outer sheet and the layers of the inner sheet, a distance is maintained. The invention furthermore relates to an assembly of a roller blind according to the invention and a double glazing unit. | 06-25-2009 |

| 20090017423 | DROPLET JET SYSTEM FOR CLEANSING - The system includes a reservoir for fluid; a droplet generator for creating a stream of fluid droplets from the fluid wherein the velocity of the stream of droplets is within a range of 20 meters per second to 200 meters per second and the size of the droplets is within a range of 5 microns to 200 microns. A nozzle or nozzles direct the stream of droplets to safely clean a selected tooth or teeth surface area. The specific momentum of effective fluid droplets within the stream of fluid droplets is important in safe and effective cleaning. | 01-15-2009 |

| 20100035200 | GAS-ASSISTED SYSTEM FOR FLUID DROPLET GENERATION IN AN ORAL CARE SYSTEM - An oral care system using a stream of fluid droplets for cleaning teeth includes a hand-held portable oral care device having a handle portion with a nozzle at a forward end thereof, a source of dental fluid and a source of pressurized gas, between 10-30 bar, both located in the handle portion. The system also includes a base unit which includes a reservoir tank for pressurized air, a reservoir tank for fluid, and a compressor connected to the gas reservoir. The handle includes valves for controlling the release of pressurized gas and fluid from the handle to the nozzle. Connecting ducts are arranged from the fluid and pressurized gas source to the nozzle such as to accelerate the pressurized gas droplets from the nozzle to a desired velocity. | 02-11-2010 |
