    • In accordance with one exemplary embodiment the invention provides a multi-parameter fiber optic sensing system with an aperiodic sapphire fiber grating as sensing element for simultaneous temperature, strain, NOx, CO, O2 and H2 gas detection. The exemplary sensing system includes an aperiodic fiber grating with an alternative refractive index modulation for such multi-function sensing and determination. Fabrication of such quasiperiodic grating structures can be made with point-by-point UV laser inscribing, diamond saw micromachining, and phase mask-based coating and chemical etching methods. In the exemplary embodiment, simultaneous detections on multi-parameter can be distributed, but not limited, in gas/steam turbine exhaust, in combustion and compressor, and in coal fired boilers etc. Advantageously, the mapping of multiple parameters such as temperature, strain, and gas using sapphire aperiodic gratings improves control and optimization of such systems directed to improve efficiency and output and reduce emissions.

    • A fluorescence microscopy sequencer comprises a fluid transport subsystem in which reagents are pumped through a series of multi-port valves to a mixer or one or more flow cells, or directly into the flow cell(s). The one or more multi-port valves can be mounted upon a fluids manifold having syringe tubes mounted on the opposite side. Mounted on a movable support, the manifold may be brought into and out of fluid communication with a storage block comprising the plurality of reagents. In another embodiment, the sequencer comprises a beamsplitter indexer that facilitates the quick and reliable switching of filter cubes through use of a stepper motor. In yet another embodiment, a motion control system is provided in which an inertial reference is interposed between and directly coupled to a first and second axis of control, thereby minimizing any low structural resonant frequencies and enabling high performance (high frequency response) motion control.
    • 荧光显微镜测序仪包括流体输送子系统,其中试剂通过一系列多口阀泵送到混合器或一个或多个流动池,或直接进入流动池。 一个或多个多口阀可以安装在具有安装在相对侧上的注射管的流体歧管上。 安装在可移动的支撑件上,歧管可以与包含多个试剂的储存块进出流体连通。 在另一个实施例中,定序器包括分束器分度器,其通过使用步进电动机有助于快速可靠地切换过滤器立方体。 在另一个实施例中,提供了一种运动控制系统,其中惯性参考系被插入到第一和第二控制轴之间,并且直接耦合到第一和第二轴控制,从而最小化任何低结构谐振频率并实现高性能(高频响应)运动控制。
