A door attachment method assembles a door with a high degree of accuracy. Embodiments include a primary fastening step of bolting hinges to attachment surfaces of a vehicle body; a door panel position measurement step of measuring a relative position of a door panel in an opening when a door is brought into a cantilevered state and the hinges are fastened; a loosening step of loosening the fastening; a door position correction step of moving the door within the attachment surfaces based on a measurement result in the door panel position measurement step; and a secondary fastening step of re-fastening the hinges to the attachment surfaces. Throughout the primary fastening step, the door panel position measurement step, the loosening step, the door position correction step, and the secondary fastening step, a state where clamps respectively grip the hinges to cause the hinges to abut the attachment surfaces is maintained.

The Active Beam Joint Brace (ABJB) is an improvement or a compliment to the current technology of protecting steel beam structured buildings such as tuned mass dampers near the top floors of sky scrapers and large shock absorbers to reduce sway due to high winds and earthquakes. The ABJB can be also used in any type of structure i.e. bridges. It is positioned near the joint of two of the beams and therefore does not interfere with the placement of doors and windows. There are two embodiments of the ABJB: 1. A basic ABJB 2. A smart ABJB The basic ABJB reacts to any distortion of the protected beam joint and applies a counter force to the two beams in than joint. The smart ABJB is also able to forecast some of the remaining wave forces in an earthquakes duration (from the first wave forms) and proactively apply counter forces (i.e. a Rayleigh Wave). It may also adjust the frequency, magnitude and direction in combination with the other ABJB's in the structure based on the properties of the external force on the structure. Additional sensors, such as strain gauges, wind speed sensors, wind direction sensors and accelerometers can be used to gather more data about any distortion of the beam structure which can then be utilized with an intelligent algorithm to forecast and proactively resist the beam structure from distorting due to external forces.

Provided is a method for detecting at least one blade misalignment of a rotor blade of a rotor of a wind turbine having multiple rotor blades adjustable in their blade angle. The blade misalignment describes a blade angle deviation of a detected blade angle of the rotor blade from a reference blade angle. The wind turbine includes a gondola having the rotor and an azimuth adjustment device in order to adjust the gondola in an azimuth alignment having an azimuth angle, and to adjust the azimuth alignment. The azimuth angle is tracked using the azimuth adjustment device to a predeterminable azimuth setpoint angle, and the blade misalignment is detected as a function of an azimuth movement of the gondola. Provided herein is detection of aerodynamic imbalances with reduced costs.
