摘要： A system for detecting and diagnosing a faultive state of an airplane engine, including: at least one vibration sensor attached to an airplane; a reference model database construction unit; and a fault detection and diagnosis unit which estimates a parameter of a model, obtains a test variable and a numerator coefficient value difference of a transfer function between the models, and the covariance of parameter estimation error, and diagnoses the faultive state and the faultive cause of the airplane engine. Accordingly, the present invention can determine the faultive state and the detective cause of the airplane engine using the vibration data of the airplane engine.

摘要： An apparatus for adjusting a height of a suction brush for use in a vacuum cleaner includes a height adjusting knob rotatably disposed in an inserting recess formed in the suction brush, and having an inclined part formed thereon, so that a height of the suction brush from a surface to be cleaned is varied as a position of the height adjusting knob rotated, a supporting member to support the suction brush in contact with the inclined part thus to allow the suction brush to be ascended and descended by the inclined part, and a passage disposed between an inner circumferential surface of the inserting recess and an outer circumferential surface of the height adjusting knob to pass fine dirt therethrough. With the passage, the fine dirt is not tied up between the inner circumferential surface of the inserting recess and the outer circumferential surface of the height adjusting knob. Accordingly, the rotation of the height adjusting knob is not restricted or obstructed due to the fine dirt.
