摘要： An electronic lock includes a rotatable core movable within an outer body. The rotatable core includes a piezo-electric actuator configured to move a tumbler blocking member into or out of interfering engagement with one or more tumblers. Tamper circuitry coupled with the piezo-electric actuator is configured to resist an externally induced acceleration of the electronic lock by shunting electrical power produced by an externally induced motion of the piezo-electric actuator back to the piezo-electric actuator.

摘要： A piezoelectric actuator and a method of assembling and employing a piezoelectric actuator. This method comprises the steps of positioning an expandable piezoelectric material inside a case, and enclosing a vaporizable liquid in the case. The case is positioned in a high temperature environment; and the liquid vaporizes, in that high temperature environment, over a given period of time, to maintain the temperature of the piezoelectric material below a given value for said period of time. Preferably, the vaporizing liquid maintains the temperature of the piezoelectric material substantially constant over that period of time. Also, preferably the case is provided with a pressure responsive valve that opens and closes, in the high temperature environment, to expose the liquid to that environment and control the vaporization of the liquid to maintain the temperature of the piezoelectric material substantially constant over the period of time.

摘要： A computer model of a gas turbine is analyzed using finite element analyses to determine the height of support jacks underneath the casing of the gas turbine. The computer model defines the gas turbine casing as an array of data points. Each data point includes information regarding the spatial location of the point and the mass (or weight) of the gas turbine with respect to that point. By applying finite element analysis, the load due to gravity and resulting deformation at each point on the gas turbine can be predicted. Jacks supporting the gas turbine are also simulated in the model to compensate for the casing deformation due to gravity. Results using the proposed iterative algorithm indicate the correct jack heights to minimize casing distortion.
摘要翻译：使用有限元分析来分析燃气轮机的计算机模型，以确定燃气轮机壳体下方的支撑千斤顶的高度。计算机模型将燃气轮机壳体定义为数据点阵列。每个数据点包括关于该点的空间位置和燃气涡轮机相对于该点的质量（或重量）的信息。通过应用有限元分析，可以预测燃气轮机上每个点处的重力负荷和所造成的变形。在模型中还模拟支持燃气轮机的插座，以补偿由于重力引起的套管变形。使用所提出的迭代算法的结果表明正确的插座高度以最小化套管失真。
