The adaptive system and method for ultrasound sensing comprises re-evaluating over time the detection threshold for predetermined sensing positions along the scanning direction to cope for the static target and environment changes at the sensing positions. An angle between the silhouette edge and an adjacent silhouette edge in the image is determined, and the display format for the silhouette edge is selected based on the angle. Therefore, the present invention enables a more economical method of utilization of wind energy to make better use of energy resources without causing to environmental pollution. An electrical coupling and nut delivery tube are integrated to facilitate connection in confined spaces.
