摘要： A linear actuator device. A first mode of operation uses a single clamping technique whereby a piezoelectric element is slowly expanded, in a way such that a clamping force between that element and its base holds it in place. The piezoelectric element is then contracted in size very quickly, and the inertia created by that action overcomes the clamping force and moves relative to the base. A second mode uses a double clamping technique where first the rear is clamped and the front moved forward then the front is clamped and the rear moved forward. All of these embodiments preferably use semiconductor materials, enabling formation of very thin layers and small devices.
摘要翻译：线性致动器装置。第一操作模式使用单一夹紧技术，由此压电元件缓慢地膨胀，使得该元件与其基座之间的夹紧力将其保持就位。然后压电元件的尺寸非常快地收缩，并且由该动作产生的惯性克服了夹紧力并相对于基座移动。第二种模式使用双夹紧技术，其中首先将后部夹紧，并且前部向前移动，然后前部被夹紧，后部向前移动。所有这些实施例都优选使用半导体材料，能够形成非常薄的层和小的器件。

摘要： Surgical system for phacoemulsification providing infusion fluid apparatus and aspiration or evacuation apparatus to supplement the action of ultrasound vibrational energy applied to the surgical target area via a surgical handpiece. The supplemental apparatus for infusion and aspiration maintains a stable control volume within the anterior chamber of the human eye during a phacoemulsification procedure. Integration of the fluid pressure and flow sensors in a close proximity of less than 8 inches with the surgical handpieceand reduction of communicating fluid pressure and flow rate via fluid conduits allows fast system response time and accurate operation control.

摘要： A method and apparatus for operating on the human eye detects changes in load, more specifically, mechanical impedance, of the transducer and controls aspiration based on the load changes. A change from a lower load to a higher load indicates that harder tissue is being encountered and accordingly causes aspiration amount to increase. Conversely, a change from a higher load to a lower load indicates that aspiration amount should be quickly decreased since the tissue which is being encountered is softer. One way to detect the impedance is by a sensor, e.g., a piezoelectric element coupled to the operating needle detecting the movement thereof.
摘要翻译：用于在人眼上操作的方法和装置检测换能器的负载变化，更具体地，机械阻抗，并根据负载变化控制抽吸。从较低负载到较高负载的变化表明，正在遇到较硬的组织，因此导致吸入量增加。相反，从较高负荷到较低负荷的变化表明，由于遇到的组织较软，所以吸入量应该快速降低。检测阻抗的一种方式是传感器，例如耦合到检测其运动的操作针的压电元件。
