摘要： An apparatus comprises a rotatable shaft and first and second targets coupled to the rotatable shaft so as to rotate therewith, a first probe for transmitting a first transmission signal to the first target and receiving a first response signal from the first target, and a second probe for transmitting a second transmission signal to the second target and receiving a second response signal from the second target. The apparatus further comprises a processor operatively coupled to the first and second probes for determining a torsional displacement of the shaft based on the first and second response signals received by the first and second probes, respectively. The processor then determines a torque imposed on the rotatable shaft based on its torsional displacement.

摘要： An apparatus for determining the torque imposed on a rotatable shaft. The shaft has at least four paired probes, paired horizontal probes and paired vertical probes. The horizontal probes are positioned 90 degrees apart from the vertical probes. If the shaft moves horizontally, the time of arrival detected by the first horizontal probes will be later than a nominal value and the time of arrival for the second horizontal probes will be earlier than a nominal value with the same amount of error. Combining data from the first and second horizontal probes will then automatically cancel out any error from horizontal motion. Similarly, combining data from vertical probes will eliminate the error due to vertical movement. Because any radial movement is a combination of horizontal and vertical movements, the use of the probes removes errors due to movement in any direction.
摘要翻译： 一种用于确定施加在可旋转轴上的扭矩的装置。 轴具有至少四个成对的探针，成对的水平探针和成对的垂直探针。 水平探头与垂直探头分开定位90度。 如果轴水平移动，则由第一水平探头检测到的到达时间将晚于标称值，并且第二水平探头的到达时间将早于具有相同误差量的标称值。 结合第一和第二水平探头的数据将自动消除水平运动中的任何误差。 类似地，组合来自垂直探测器的数据将消除由于垂直移动引起的误差。 因为任何径向运动都是水平和垂直运动的组合，因此使用探头会消除由于任何方向的运动引起的误差。

摘要： A magnetic-resonance-imaging (MRI) scanner subassembly. In one subassembly, a preferably annularly-cylindrical-shaped enclosure contains a first vacuum, and an MRI gradient coil assembly is located within the enclosure in the first vacuum. Preferably, an annularly-cylindrical housing is included which is coaxially aligned with the enclosure and contains a second vacuum which is higher than the first vacuum, and an MRI superconductive main coil is located within the housing in the second vacuum. In another subassembly, an MRI gradient coil assembly has a threshold excitation frequency, and an isolation mount assemblage supports the MRI gradient coil assembly.
