    • An apparatus for extracting bodily fluid (e.g., whole blood) from a user's finger includes a housing with a lancing mechanism and a clamping mechanism attached to thereto. The clamping mechanism includes a lower arm assembly and an upper arm assembly. The upper and lower arm assemblies are operatively connected such that when a user's finger applies a user force to the lower arm assembly and displaces the lower arm assembly from a first to a second position, the upper and lower arm assemblies cooperate to engage the user's finger with a compressive force that is greater than the user force. In addition, the lancing mechanism is configured to lance a target site on the user's finger while the upper and lower arm assemblies are cooperating to engage the user's finger. Thereafter, the compressive force serves to extract a bodily fluid sample from the lanced target site.

    • An accelerator comprises a plurality of accelerating cells arranged to convey a beam, adjacent cells being linked by a coupling cell, the coupling cells being arranged to dictate the ratio of electric field in the respective adjacent accelerating cells, at least one coupling cell being switchable between a positive ratio and a negative ratio. Such an accelerator in effect inserts a phase change into the E field by imposing a negative ratio, meaning that the beam will meet a reversed electric field in subsequent cells and will in fact be decelerated. As a result, the beam can be developed and bunched in early cells while accelerating to and/or at relativistic energies, and then bled of energy in later cells to bring the beam energy down to (say) between 100 and 300 KeV. Energies of this magnitude are comparable to diagnostic X-rays, where much higher contrast of bony structures exists. Hence the accelerator can be used to take kilovoltage portal images.
    • 加速器包括多个加速单元,其被布置成传送波束,相邻单元由耦合单元链接,所述耦合单元布置成指示相应相邻加速单元中的电场的比率,至少一个耦合单元可在 正比率和负比率。 这样的加速器实际上通过施加负比率将相位插入到E场中,这意味着光束将在随后的单元中遇到反向的电场,并且实际上将被减速。 结果,可以在加速到和/或相对论能量的同时在早期的单元中显影和聚束光束,然后在稍后的单元中排出能量,以将光束能量降低到(例如)100和300KeV之间。 这种量级的能量与诊断X射线相当,骨骼结构的对比度高得多。 因此,加速器可用于采取千伏门户图像。

    • This device allows the variation of the coupling between two points in an RF circuit in a very simple way while maintaining the RF phase relationship and varying the relative magnitude of the RF fields. The device is characterized by a simple mechanical control of coupling value, that has negligible effect on the phase shift across the device. This is achieved by the simple rotation of the polarisation of a TE111 mode inside a cylindrical cavity. Such a device does not contain resistive elements, and the sliding mechanical surfaces are free from high RF currents. This device finds an application in standing wave linear accelerators, where it is desirable to vary the relative RF field in one set of cavities with respect to another, in order that the accelerator can operate successfully over a wide range of energies.
    • 该装置允许以非常简单的方式在RF电路中的两个点之间的耦合的变化,同时保持RF相位关系并改变RF场的相对幅度。 该器件的特征在于耦合值的简单机械控制,对于跨器件的相移具有可忽略的影响。 这通过在圆柱形腔内的TE111模式的极化的简单旋转来实现。 这种装置不包含电阻元件,并且滑动机械表面没有高RF电流。 该装置在驻波线性加速器中发现了一种应用,其中期望相对于另一组空腔改变相对RF场,以便加速器能够在宽范围的能量范围内成功地运行。
