    摘要： An apparatus and method for wirelessly determining position and orientation of a first object relative to a second object in six dimensions, including one or more recording assemblies and one or more identification-coded or orientation-coded optical transponders. The positions of the recording assemblies are fixed relative to the first object and the transponders are fixed relative to the second object. A light source in each recording assembly emits light into space that is received, modulated, and retransmitted back by each transponder to a photodetector assembly in the recording assembly. The identification-coded optical transponder modulates the retransmitted light with a unique fixed code. The orientation-coded optical transponder modulates the retransmitted light with a unique fixed code that depends upon the direction of the incident light. The photodetector assemblies provide one or two independent position parameters for each transponder and two independent orientation parameters for each orientation-coded transponder. The system includes a combination of recording assemblies and transponders that provides at least six independent measured parameters.

    摘要： A light beam deflector comprises an initial beam deflector that imparts a small initial deflection, and a beam deflection amplifier that increases the initial small deflection by a multiplication factor. There are five embodiments of the initial beam deflector. The first four use a pair of lenses and a piezoelectric actuator affixed to one lens. When the parallel lens axes are separated by a distance, the incident light beam will be deflected by a small angle, typically up to about 5°. The fifth embodiment comprises a mirror affixed to a piezoelectric actuator, which tilts the mirror. The beam deflection amplifier has five embodiments. The first is a Keplerian telescope lens first stage and a negative lens system second stage. The first is a Galilean telescope lens first stage and a negative lens system second stage. The third embodiment is either a Keplerian or Galilean telescope lens alone. The fourth embodiment replaces the single second lens of the first stage with a compound lens system. The fifth embodiment uses a special sphere lens alone.

    摘要： An optical switching system employing switching modules. Each module comprises (a) a source channel, (b) a transmitting element, (c) a receiving element, and (d) a destination channel. The transmitting element directs the source channel signal to a destination channel. The transmitting element includes an initial beam deflector and a beam deflection amplifier. The receiving element includes a beam deflection compressor and a beam aligner. One embodiment of the initial deflector is a pair of focusing lenses, one of which is displaced by a piezoelectric actuator. When one lens is displaced a distance d, the output light beam has a deflection angle &agr;=(f1+f2)/f2. The beam deflection amplifier multiplies the small angle &agr; by a transfer function F to result in a beam with a deflection angle F&agr;. The receiving element is the transmitting element in reverse. The first system configuration connects a single channel to one of a number of channels. The second system configuration connects a group of M channels with another group of N channels. The third system configuration cross-connects N channels in an arbitrary manner.

    摘要： A retroreflecting modulator including a lens, a light guide, a light modulator, and a reflective surface. Incident light falls on the lens, where it is focused as a spot on a focal surface. The light guide transmits the focused light to the light modulator, where it is modulated and reflected back, via the reflective surface and light guide, to the lens. The lens emits the modulated light in the opposite direction as the incident light. The preferred light-receiving and focusing device is a specialty sphere lens, the preferred light guide is a fiber optic plate, and the preferred light modulator is a liquid crystal modulator. The retroreflecting modulator may be spatially-unresolvable, where a single signal modulates the light, or spatially-resolvable, where the modulation signal depends upon the direction of the incident light.

    摘要： An apparatus for extending the light deflection angle, so a light beam can be dynamically controlled within ±90°, pitch and yaw. The device comprises an initial dynamic beam deflector and a compound light beam direction mapper. The beam direction mapper includes a beam size reducer, a beam transmission adapter, and a projector. An initial light beam from a light source is deflected a small amount by the initial dynamic beam deflector. The initially deflected light beam is focused by the beam size reducer to a light energy spot on the beam transmission adapter, which transfers the light spot to the projector. The projector emits an output light beam at the far field of its output space with an output deflection angle larger than the initial deflection angle. All components are based on classical geometry optics and the energy of the output light beam is within an order of magnitude of that of the input light beam.

    摘要： Methods and systems for knowledge pattern search and analysis for selecting microorganisms based on desired metabolic properties or biological behaviors are disclosed in various embodiments of the invention. In one embodiment of the invention, a computer-implemented method for selecting a purpose-specific microorganism first compiles microorganisms' profiles by linking each microorganism's methanogenic, hydrogenic, electrogenic, another metabolic property, and/or another biological behavior to genetic and chemical fingerprints of metabolic and energy-generating biological pathways. Then, based on the compiled profiles of the microorganisms, the computer-implemented method groups the microorganisms into pathway characteristics using machine-learning and pattern recognition performed on a computer system, and subsequently generates a prediction called “discovered characteristics” for a desired metabolic property or a desired biological behavior of at least one microorganism. Furthermore, a profile match score may be calculated to indicate usefulness of one or more microorganisms for renewable energy generation from biological waste materials or wastewater.

    摘要： A method and an apparatus for separating a foreground image are disclosed. The method includes obtaining an input image and depth information of the input image; roughly dividing the input image to obtain a rough foreground region based on the depth information of the input image; obtaining motion information of the input image, and generating a three-color image from the rough foreground region based on the motion information; and separating the foreground image from the generated three-color image. According to the method, the three-color image is generated based on the depth information and the motion information, thus a foreground object can be accurately separated from the three-color image.
