    • A system (10) for determining the longitudinal position of a displaceable element (12) positioned between two substantially orthogonally laterally opposing displacement sensors (14a, 14b) measures a distance (44a, 44b) from each displacement sensor (14a, 14b) to the displaceable element (12). The displaceable element (12) has a tapered thickness (32) along its length (36). A change in the longitudinal position of the displaceable element (12) causes the proximity sensors (14a, 14b) to each detect their distance (44a, 44b) to the displaceable element (12), which distances (44a, 44b) then correspond directly to the local thickness (32) and thus the longitudinal position of the displaceable element (12). The system calculates the position of the displaceable element (12). The system (10) can easily factor out errors in measured lateral proximity position of the displaceable element (12), since an erroneous proximity to one sensor (14a, 14b) is equal and opposite to an erroneous proximity to the other (14a, 14b).
    • 用于确定位于两个基本上正交的横向相对的位移传感器(14a,14b)之间的位移元件(12)的纵向位置的系统(10)测量从每个位移传感器(14a,14b)到 可移位元件(12)。 可移动元件(12)沿其长度(36)具有锥形厚度(32)。 可移动元件(12)的纵向位置的改变使得接近传感器(14a,14b)各自检测到与可移动元件(12)的距离(44a,44b),该距离(44a,44b)然后直接对应 到局部厚度(32),从而可移动元件(12)的纵向位置。 系统计算可移位元件(12)的位置。 由于与一个传感器(14a,14b)的错误接近等于并相对于另一个传感器(14a,14b)的错误接近,系统(10)可以容易地排除测量的可移动元件(12)的横向接近位置的误差 )。

    • Disclosed are embodiments of apparatus and methods for separating particles in a fluid stream by size. In one illustrative embodiment of an apparatus for separating such particles, a housing is provided, which defines a channel for a fluid stream containing particles. A suction channel is provided, which terminates at a suction port. The suction port is positioned adjacent to the fluid stream. A blowing channel terminating at a blowing port is also provided. The blowing port is positioned adjacent to the suction port such that the suction port is positioned in between the fluid stream and the blowing port. The blowing port and the suction port are configured to create a low pressure region and thereby redirect the first fluid stream towards the low pressure region.

    • An Optical Parametric Oscillator capable of rapid or broadband frequency tuning by non-mechanical or mechanical means includes a resonant cavity with one or more non-linear crystals in an optical path thereof. The non-linear crystals may be driven by actuators. A pump laser pulse is transmitted into the resonant cavity with one or more seed beams having a desired wavelength. The output beam from the resonant cavity may have the same center wavelength as the one or more seed beams which may be modulated at a frequency larger than that of the pump laser, or the inverse of the pulse duration. The OPO may be used in Light Detection And Ranging or Differential Absorption LIDAR analysis by intra-pulse modulation of output to measure absorption at multiple frequencies for each pulse of a pump beam. Sum Frequency Generator configurations may be suitable for narrow and broadband UV generation.
