A color translating UV microscope for research and clinical applications involving imaging of living or dynamic samples in real time and providing several novel techniques for image creation, optical sectioning, dynamic motion tracking and contrast enhancement comprises a light source emitting UV light, and visible and IR light if desired. This light is directed to the condenser via a means of selecting monochromatic, bandpass, shortpass, longpass or notch limited light. The condenser can be a brightfield, darkfield, phase contrast or DIC. The slide is mounted in a stage capable of high speed movements in the X, Y and Z dimensions. The microscope uses broadband, narrowband or monochromat optimized objectives to direct the image of the sample to an image intensifier or UV sensitive video system. When an image intensifier is used it is either followed by a video camera, or in the simple version, by a synchronized set of filters which translate the image to a color image and deliver it to an eyepiece for viewing by the microscopist. Between the objective and the image intensifier there can be a selection of static or dynamic switchable filters. The video camera, if used, produces an image which is digitized by an image capture board in a computer. The image is then reassembled by an overlay process called color translation and the computer uses a combination of feedback from the information in the image and operator control to perform various tasks such as optical sectioning and three dimensional reconstruction, coordination of the monochromater while collecting multiple images sets called image planes, tracking dynamic sample elements in three space, control of the environment of the slide including electric, magnetic, acoustic, temperature, pressure and light levels, color filters and optics, control for microscope mode switching between transmitted, reflected, fluorescent, Raman, scanning, confocal, area limited, autofluorescent, acousto-optical and other modes.

This invention deals with novel method and apparatus for positioning and motion control of the elements (mirrors) of a Fresnel reflector solar concentrator tracking heliostat array wherein the elements are suspended with the center of mass below the swivel point, or have an internal-swivel. This achieves an advantageous natural vertical stability. The torque to produce angular deflection, and rotational motion is provided separately by an electric wind force due to electrons, ions, and / or neutrals; or in combination with an induced and / or permanent dipole coupling to an electronic grid. Thus forces and torques are produced without the use of internal moving parts such as in motors. The instant invention exceeds the capability of conventional systems. It is ideally suited for maximization of solar energy focused by a low-profile concentrator array onto a receiver. Since there are no internal moving parts, the instant invention provides less costly and greater ease of manufacture. Dynamic motion can be controlled over a wide range of dimensions from nanometers to decimeters.

The proposed Dynamic Motion Vector Analysis method applies to the motion compensation module of a video decoder system. The method analyzes the motion-vectors of a given region of picture frame and outputs a set of regions to be fetched from the reference frames stored in the external memory. The size and number of regions are decided by a hierarchical method that uses a set of user-defined input thresholds. Pre-processing of the motion vectors associated with the given region allows the method to handle reference data to be fetched from multiple reference frames in the same framework. A complementary dynamic batch (region of operation) size strategy that works along with MV-analysis is also proposed to help utilize the on-chip memory resources more efficiently.

The invention discloses a high-dynamic weak-signal rapid capture method for a direct sequence spread spectrum system, belonging to the field of radio communication. Because a spread spectrum carrier has a chirp signal characteristic under the condition of high-dynamic motion (high-speed and high-acceleration), the high-dynamic weak-signal rapid capture method comprises the steps of: firstly, carrying out carrier Doppler frequency compensation by using a time frequency focusing characteristic of fractional order Fourier transform; secondly, carrying out incoherent accumulation on a spread frequency signal by using an order resolving capacity of the fractional order Fourier transform; and finally, carrying out capture judgment on the signal in an order Fourier domain by using a constant false alarm rate detection technology.
