摘要： An electrochemical cell includes a measuring electrode and a reference electrode. The reference electrode includes a flowing liquid junction between a reference fill fluid and a sample. The flowing liquid junction is configured to inhibit particles from blocking or obstructing it. In one aspect a particle filter is provided before the flowing liquid junction to prevent particles from the fill fluid from entering the flowing liquid junction. In another aspect a particle filter is provided after the flowing liquid junction to prevent particles in the sample from entering the flowing liquid junction. In another aspect the flowing liquid junction has a diameter that generally increases from an aperture proximate the fill fluid to an aperture proximate the sample. On example of such a configuration is a tapered flowing liquid junction.

摘要： A graphical user interface for direct control of data displayed in a window-based computing environment. A slider element is displayed which is variable in size according to user input. The slider defines a selected area of an image, which is then displayed. The scope of the selected area corresponds to the size of the slider. The resizable slider is then resized by a user's direct manipulation, e.g. by a click-and-drag technique, to redefine the selected area, which is then displayed. The scope of the redefined selected area corresponds to the size of the resized slider. Accordingly, a user directly controls (by resizing the slider) the scope of data displayed in a window, and directly controls the presentation of data by translating the slider to define various selected areas. More than one independently resizable slider may intersect to define the selected area and provide independent control of scope in various directions.

摘要： An ion sensitive field effect transistor pH sensor is provided with an improved sensor gate configuration. Specifically, a tantalum oxide-sensing gate is disposed on top of an alumina layer. The tantalum oxide-sensing gate provides advantageous sensitivity, while the alumina barrier layer increases sensor longevity in situations where the sensor is exposed to caustic cleaning processes such as Clean In Place processes.

摘要： An inexpensive polyimide-free alignment layer comprising a mixture of an epoxy and a reactive liquid crystal material is used for fabricating liquid crystal displays (LCDs). The alignment layer can be cast onto a previously aligned layer, without destroying the alignment of the underlying layer, thus allowing for monolithic fabrication of compensator stacks, without film transfer lamination.

摘要： An apparatus for optically coupling a light source with a light-receiving end face of an optical waveguide comprises a lens for focusing a light beam emitted from the light source at a focal point on the light-receiving end face of the optical waveguide. An adaptive coupler, positioned in the optical path, is responsive to a beam steering control signal for steering and aligning the focal point relative to the light-receiving end face of the optical waveguide. In one form, the adaptive coupler comprises a pair of transparent substrates having confronting, parallel inner faces, the inner face of one of the pair of substrates carrying a beam intercepting, optically transparent, constant potential electrode and the inner face of the other of the pair of substrates carrying an electrically resistive, beam intercepting, optically transparent film. A pair of spaced apart electrodes in electrical contact with the film apply a linear voltage gradient along the film. An electro-optical phase shifting medium is disposed between the confronting inner faces of the substrates. The application of selected voltages to the electrodes creates a linear voltage gradient along the aforementioned film on the inner face of the one substrate resulting in a linearly varying electric field between that film and the constant potential electrode creating a corresponding linear variation in the refractive index of the liquid crystal medium and a linear wavefront tilt in the intercepting optical beam.

摘要： A two-stage drive waveform switches a DFLC from a high tilt state to a low tilt state quickly and without scattering. A relaxation voltage is applied to delay the onset of the high amplitude high frequency kick voltage when switching from a high tilt state to a low tilt state. The relaxation voltage allows the molecules to ‘relax’ in accordance with their own elasticity towards their low tilt state in the direction of the average azimuth angle of the low tilt state. The kick voltage is then applied to drive the molecules quickly to the low tilt state. Optimal switching time and the desired molecular response is achieved by delaying the onset of the large kick voltage via application of the relaxation voltage. The relaxation voltage may constitute a lower amplitude holding voltage, a small or zero DC voltage or a smooth windowing of the kick voltage.
摘要翻译：两级驱动波形将DFLC从高倾斜状态快速切换到低倾斜状态，无散射。当从高倾斜状态切换到低倾斜状态时，施加弛豫电压以延迟高幅度高频踢脚电压的开始。松弛电压允许分子在低倾斜状态的平均方位角的方向上根据它们自身的弹性朝着它们的低倾斜状态而松弛。然后施加击穿电压以快速将分子驱动到低倾斜状态。通过施加松弛电压来延迟大的踢脚电压的开始来实现最佳切换时间和期望的分子响应。弛豫电压可以构成较低的振幅保持电压，小的或零的直流电压或踢脚电压的平滑窗口。
