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.

The embodiment of a system for remotely controlling a wireless communication mobile phone device senses its space coordinates. GPS and other data is transmitted between mobile phones to alert and/or update a user to the fact that their phone has reached a significant threshold locations, 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 transmit and received to alert and/or update information of the mobile phone users. This is done for improving security and save lives, controlling classified communications, improving privacy, improving machinery performance, measuring distances and speed between mobile phones, alerting and/or updating personnel 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.

摘要:
Provided is a device, system, and method for the fixation of the spine, which provides dynamic support for spinal vertebra so as to better control load transfers and avoid deterioration of the bone of adjacent spinal vertebra. The present invention can be applied posteriorly to support the vertebra of the spine or can be adapted to attach to existing spinal constructs.
摘要:
The present invention provides a novel minimally invasive surgical system and method for introducing instruments and/or biomaterial into the interior of a bone, particularly the interior of a vertebral body, using a unique cannulated screw that is sized and configured to penetrate the cortical bone and thereby provide access to the interior of the bone through the integral cannula of the screw. That same screw having a screw head that is then adaptable to employ a connector for securely holding a connecting device, such as a spinal rod or plate that can then be used to fix bones or bone fragments together. A method of fixing bones or bone fragments is also provided.
摘要:
Provided is a surgical rod fixation assembly having a pedicle screw for insertion into spinal bone of a subject, the pedicle screw having a polyaxial mounted coupling member for driving the pedicle screw into bone on or off axis and coupling the pedicle screw to an orthopaedic device such as a spinal rod by means of a slidable coupling action.
摘要:
A repair system including a closure prosthesis and deployment device, and associated methods for repairing any imperfection including a flaw, hole, tear, bulge, or, in some cases, a deliberate cut or incision in any tissue including an intervertebral disc. The prosthesis has first and second side portions with a connecting central portion, and is designed to span an imperfection with opposite ends positioned on opposite sides of the imperfection. The prosthesis may include anchoring features including barbs and/or members that extend transversely. The deployment device can include a canula for positioning the prosthesis near the imperfection, and, in some cases, a mechanism that may cause the two sides of the prosthesis to be deployed in a specific order.
摘要:
A novel surgical apparatus for use in orthopedic surgery procedures and a method for use is provided. The present invention includes a protective sheath which prevents fouling of the moving parts of the device by unwanted contact with surround tissue and bone. The device relates primarily to the treatment of traumatic, pathogenic, or osteoporotic bone conditions of human and other animal body systems and, more particularly, to a novel apparatus and method for manipulating the vertebral body through a less invasive, percutaneous, surgical approach.
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.
