摘要:
An aspect of the invention is directed towards a method and device for optimizing a light-up procedure of a gas turbine engine. An aspect of the method comprises repeating an engine start attempt with amended light-up parameter values or range of light-up parameter values, where the values are amended by a predefined scheme including recording the light-up parameter value or the range of light-up parameter values of each start attempt together with the light-up success rate achieved in the respective start attempts, and optimizing the light-up parameter value or range of parameter values by analyzing the recorded data after the start attempts have been finished. An aspect of the device is to provide a control unit that implements the inventive method.

摘要:
A method of starting a gas turbine engine by use of a start sequence is provided. Turbine speed and fuel delivery are coordinated so as to provide a fuel/air mixture at an ignition device allowing a successful ignition. If a successful ignition has not occurred by end of the start sequence the gas turbine engine is purged and the start sequence is repeated after the purging of the gas turbine engine.

A system and method for repairing fractured long bones. A guide wire is inserted through an opening drilled in a proximal bone segment and pushed through the intramedullary cavity of the proximal bone segment, across the fracture site and into the intramedullary cavity of a distal bone segment. A dilator is inserted over the guide wire and pushed through the intramedullary cavity into the distal bone segment to a stop at the distal end of the guide wire. A flexible tube having a radially expandable distal portion is then pushed over the guide wire into the distal bone segment and against the dilator. A compression nut is threaded over the proximal end of the guide wire to engage the proximal bone segment and compress the flexible tube. Compression of the flexible tube deploys the radially expandable distal portion to anchor the device in the distal bone segment.

A system for increasing a warhead's chance of hitting a target comprises a system for causing the warhead to deviate from its projected trajectory so that it will have an increased chance of avoiding intercepting force such as a kill vehicle a missile, an airplane, an explosive gun, a laser gun, an electron gun, radiation gun, a particles gun, a fire gun, a jet air gun, and/or a remote control guided explosive. The warhead has one or more thrusters, which cause it to deviate from its projected trajectory. An on-board computer controls the thrusters' ignition and burning time in a closed loop with an on-board Global Positioning System (GPS) unit. The GPS data is used for predicting the warhead's trajectory and to assure that the thrusters provide motion displacements of the warhead. In the event the GPS unit fails, the warhead computer and controller can be overridden by an off-board remote control. If both GPS and remote control units fail, the warhead can drop to a random mode of controlling the thruster's ignition and burning time and/or select one thruster that will tumble the warhead in space.

One embodiment of a system for remotely controlling a wireless communication mobile phone device senses its space coordinates. GPS and other data is transmitted between several mobile phones to alert and/or update a user to the fact that their phone has reached a significant threshold location, and/or has reached a significant threshold speed of within a given accuracy. A SMS message, and/or voice message, and/or a phone call, and/or a special ring, and/or a special display and/or reset signal, and/or update signal, and/or hang-up signals are cross transmitted and received to alert and/or update information of the group of mobile phone users. This is done for improving security and saving lives, controlling classified communications, improving privacy, improving machinery performance, measuring distances and speed between mobile phones, alerting and/or updating personal of hazardous locations and hazardous speeds, for forcing hang-up of phones at times of hazardous communications, providing space coordinates of missing persons and persons in danger, controlling air shows and car racing, and controlling military, fire and police men movement.

A burner apparatus for reducing carbon production, comprises a burner having a combustion chamber and a heat exchanger located within the combustion chamber. The heat exchanger has an inlet end where a mixture comprising air and fuel enters, a heat transfer section, and an outlet end from which a process mixture of air and fuel discharges into the combustion chamber and is ignited to produce a product mixture. The inlet end and outlet end are located such that the general flow direction of the air and fuel within at least a portion of the heat transfer section is substantially parallel with flow direction of the product mixture in the combustion chamber. The heat transfer section is located within the combustion chamber so as to receive thermal input from the combusted product mixture therein to heat the process mixture to a temperature sufficiently high to substantially reduce the production of solid carbon therein. The invention is also for a method for reducing carbon production.

A method of repairing an annulus of an intervertebral disc includes excising, with a cutting tool, a damaged area of the annulus, thereby creating a space in the annulus, the space being defined by first and second annulus ends; making a partial incision at the first annulus end generally adjacent to the excised area, creating a flap of annulus; stretching the flap across the space, and attaching the flap to the second annulus end.
