| 20100012482 | SPUTTERING SYSTEM AND METHOD INCLUDING AN ARC DETECTION - A sputtering system that includes a sputtering chamber having a target material serving as a cathode, and an anode and a work piece. A direct current (DC) power supply supplies electrical power to the anode and the cathode sufficient to generate a plasma within the sputtering chamber. A detection module detects the occurrence of an arc in the sputtering chamber by monitoring an electrical characteristic of the plasma. In one embodiment the electrical characteristic monitored is the impedance of the plasma. In another embodiment the electrical characteristic is the conductance of the plasma. | 01-21-2010 |

| 20110180041 | GENSET ENGINE USING AN ELECTRONIC FUEL INJECTION SYSTEM INTEGRATING AN ALCOHOL SENSOR - An open or closed loop EFI system integrating an alcohol sensor is provided on a genset engine. The EFI system provides acceptable engine performance and efficiency when using fuels or fuel blends over a wide band and when starting from a cold state, i.e., starting the engine after the engine has not run for a relatively long period of time. The alcohol sensor enables acceptable operation while the genset engine is cold. The alcohol sensor sends data to the electronic control unit (ECU) and this data, as well as data provided by other sensors that may be available such as an air flow sensor, is used to determine the optimal air-to-fuel ratio (AFR). The ECU actuates the fuel injector which sends the correct amount of atomized fuel to mix with the air flow to be combusted. The fuel mixture, at the requested AFR, enables the engine to start and operate efficiently from a cold state even if the fuel blend has been changed from a previous operation of the engine. | 07-28-2011 |

| 20080272666 | Arcuate coil winding and assembly for axial gap Electro-Dynamo Machines (EDM) - An axial gap EDM deploys as a stator coils a series of two parallel serpentine windings that each circumscribe an arc segment of a circle.

In one embodiment, each series of serpentine winding are separated by a gap so that they can be inserted on the stator disk from the edge. A separate rotor disk is adjacent each side of this stator disk. In another embodiment, each series of serpentine winding are separated by a gap, so they can be inserted to surround a single rotor disk which has two series of magnets disposed on opposite sides. | 11-06-2008 |

| 20090200890 | Winding For An Axial Gap Electric Dynamo Machine - The stator of an axial gap dynamoelectric machine has at least one substantially planar coil arrays formed by joining two or more sub-coils. Each sub-coil has a serpentine path about the stator perimeter that includes radial segments disposed to generate a Lorenz force with respect to the rotor magnets. The radial segments of the serpentine path joined by alternating inner and outer tangential segments. Each sub-coil starts with a proximal end at an outer tangential segments and a distal end about or within an inner perimeter of the inner tangential segments. Each sub-coil is joined at the distal end with another sub-coil to form the winding coil such that the proximal ends of the sub-coils constitute the two terminals of the planar coil array. This arrangement conveniently places both terminals of the planar coil array at the outer perimeter of the stator while also raising the winding inductance to a level more compatible with conventional motor power supplies. | 08-13-2009 |

| 20110148116 | Antenna Mounted Wind Power Generator - A cellular communication tower is adapted to support a vertical axis wind turbine (VAWT) that includes a generator mechanism. The signal and power cable for the communication antennas run through the central axis or bore of the generator. The blades of the VAWT are disposed so as to avoid interferences with communication signals. The tower preferably deploys an open truss construction to avoid the impact of periodic pressure pulse as the turning blades shift out of alignment from shading the tower. Thus, with an open truss tower the turbine blades can be a larger size and still not cause such pressure pulses. | 06-23-2011 |
| 20110158817 | VERTICAL AXIS WIND TURBINE AIRFOIL - A vertical axis wind turbine airfoil is described. The wind turbine airfoil can include a leading edge, a trailing edge, an upper curved surface, a lower curved surface, and a centerline running between the upper surface and the lower surface and from the leading edge to the trailing edge.
