20090284018 | VERTICAL AXIS TURBINE TO GENERATE WIND POWER - Usage of wind turbine systems that convert wind energy to electricity is expanding. The present inventor recognized that conventional systems are not suitable for more densely populated regions, are not effective in regions having lower average wind speeds, and are not visually appealing, quiet, and expandable. Accordingly, he devised, among other things, an exemplary vertical-axis wind turbine system that includes a novel wind turbine having cup-like blades that exhibit air-foil characteristics. The air-foil characteristics dramatically improve the efficiency of the turbine, not only making it effective at lower wind speeds than conventional wind turbines, but also more tolerant of extreme wind conditions. The exemplary system is compact and suitable for roof-top and water-surface installations. Additionally, the exemplary system includes a set of one or more hollow-bore field-wound electric generators, which are not only stackable, but selectively engageable based on measured wind speeds to provide full spectrum electrical generation. | 11-19-2009 |

20080314394 | Percutaneous myocardial revascularization - Devices and methods for creating a series of percutaneous myocardial revascularization (PMR) channels in the heart. One method includes forming a pattern of channels in the myocardium leading from healthy tissue to hibernating tissue. Suitable channel patterns include lines and arrays. One method includes anchoring a radiopaque marker to a position in the ventricle wall, then using fluoroscopy repeatedly to guide positioning of a cutting tip in the formation of multiple channels. Another method uses radiopaque material injected into each channel formed, as a marker. Yet another method utilizes an anchorable, rotatable cutting probe for channel formation about an anchor member, where the cutting probe can vary in radial distance from the anchor. Still another method utilizes a multiple wire radio frequency burning probe, for formation of multiple channels simultaneously. Still another method utilizes liquid nitrogen to cause localized tissue death. | 12-25-2008 |

20080225654 | Zone based repeated runout error compensation - Compensation for repeated runout (RRO) error, such as in a data storage device servo circuit, is preferably carried out by obtaining a population distribution of RRO error values from at least selected ones of a subset of tracks. An RRO error compensation value is determined for each one of the subset of tracks when a variance characteristic of said population distribution meets a selected criterion. Preferably, a first track of a storage medium has a servo field at a first angular position on the medium, a repeated runout (RRO) error compensation field at a second angular position on the medium, and a user data field at a third angular position on the medium. An immediately adjacent second track preferably has a servo field at the first angular position and a user data field at the second angular position in lieu of an RRO error compensation field. | 09-18-2008 |
