A lift system (50) for a rotor blade (16) of a wind turbine (10) includes a lifting device having a structural frame body having a root end and a tip end. The root end supports a root cradle (54) and the tip end supports a tip cradle (56). The root and tip cradles each have a profile that corresponds to at least one exterior surface of the rotor blade so as to receive and support at least a portion of the rotor blade. Due to a shape of the rotor blade, when the rotor blade is installed in the lifting device and lifted up tower, the rotor blade can experience an asymmetric loading.

This invention discloses an ultrasonic phacoemulsification handpiece with a sensor and a surge control system and a method. The central aspiration lumen of the ultrasonic phacoemulsification handpiece consists of two components of plug-in loose fit: a fixed lumen (304) and an extension lumen (305); a small pressure sensor (307) is mounted on the extension lumen (305), but still able to keep the easy-to-use size and maintain the ultrasonic performance of the handpiece. The extension lumen (305) minimizes the effect of ultrasonic vibration on the sensor (307) while maintaining sufficient stiffness for installing and removing the phacoemulsification tip (202). The design of the handpiece transducer reduces the effect of this sensor installation on the ultrasonic performance. For ultrasonic phacoemulsification cataract removal surgery, the short distance from the pressure sensor to the surgical site provides a technical solution for reliably controlling the risk of the post occlusion surge.
