Blade detection sensor having an active cooling system |
January 30, 2007 |
| A passive blade detection sensor exploits the electrically conductive trait of typical turbo machinery components such as fan, compressor and turbine blades. A permanent magnet is placed strategically adjacent to a wire coil to generate a single pulse/antipulse signal when a blade passes |

Apparatus and method for predicting failures of spinning disks in turbo-machinery |
August 31, 2004 |
| An apparatus is described for detecting the early signs of cycle-induced fatigue and thereby predicting failure of the rotating disk in turbo-machinery. It identifies change in shape of the entire disk in radial, tangential and axial directions. It examines these deformations as a fu |

Apparatus for passive damping of flexural blade vibration in turbo-machinery |
August 19, 2003 |
| A rotor blade for a turbine engine rotor assembly is provided comprising a root, an airfoil, a platform, and a means for damping vibrations in the airfoil. The airfoil includes a pocket formed into a chordwise surface. The damper is received into the pocket, forming a surface flush with |

Apparatus and method for predicting failures of spinning disks in turbo-machinery |
July 15, 2003 |
| An apparatus is described for detecting the early signs of cycle-induced fatigue and thereby predicting failure of the rotating disk in turbo-machinery. It identifies asymmetrical growth of hub-blade diameter as a predictor of incipient crack growth. Tip measurements are processed th |

Elevated tow apparatus |
June 10, 2003 |
| The present invention is for an elevated tow device made of a superstructure extending skyward from a towboat, where the superstructure raises an attachment point of a tether above 10 feet from the waterline, where the towboat is 25 feet or less in length, and a tether connecting the |

Self stabilizing tow apparatus |
September 24, 2002 |
| When it is beneficial for a towing craft, such as a boat, to tow from a point high above its center, an airfoil can be fastened to a tether for improved roll and yaw stability. In the case of a wakeboarder, the upward tow angle afforded by a tall tower improves the wakeboarder's performa |

Apparatus for producing vibration in turbo-machinery blades |
July 23, 2002 |
| A realistic study of high-cycle fatigue in turbo-machinery is dependent on a means of reproducing, in an evacuated test facility, the vibration of turbine blades caused by inhomogeneous flow in the engine. An apparatus and method are described which use magnetic eddy currents to generate |

Blade vibration control in turbo-machinery |
June 25, 2002 |
| A method for reducing blade vibration in turbo-machinery is described. The method involves inserting flow obstructions and/or gas injections upstream of vibrating blades in such a manner that power flow into the blades is reduced by means of cancellation within a modal power integral. |

Collapsible baby stroller and releasable locking and folding mechanism therefor |
August 15, 2000 |
| A baby stroller for transporting an infant over flat, rough, or uneven terrain at speeds faster than normal walking speed is disclosed. This baby stroller can be folded to make it easier to stow and transport. The folding mechanism, a unique feature of the design, enables the user to |

Apparatus and method for active control of sound transmission through aircraft fuselage walls |
June 20, 2000 |
| In aircraft, much of the noise in the cabin is a result of pressure fluctuations on the exterior fuselage skin, which vibrates the skin and causes sound pressure waves to propagate through the trim panel cavity, exciting the trim panels, which radiate into the cabin. In the present i |
