摘要： Bubble formation is monitored in a reactor such as a loop polymerization reactor which effectively operates at pressures above or near the vapor pressure of a circulating slurry liquid. The method measures a property of the reactor composition at a first location within the reactor, and then at a second location within the reactor. The process is repeated, followed by determining if the difference in measured property varies from a reference difference, derived under bubble-free conditions. When the difference in measured physical property has changed relative to the reference difference, an effect may be implemented, e.g., increase of reactor pressure, decrease of composition vapor pressure, and decrease of reactor temperature, to an extent sufficient to reduce or eliminate bubbling.

摘要： A wiremap projector apparatus for projecting moving three-dimensional images within a three-dimensional viewing space. The wiremap projector apparatus includes an array of wires disposed within a three-dimensional viewing space defined between a first and second sheet. A digital projector is positioned with respect to said array of wires such that the projector projects multiple lighted pixel lines onto the array of wires to display a moving three-dimensional image within the three-dimensional viewing space. A position control actuator includes an actuating force means for moving the one or more wires, and a position controller generates and sends a position control signal to the position control actuator. The position controller generates the position control signal from image data processed by the projector to project multiple lighted pixel lines onto the array of wires to display a moving three-dimensional image within the three-dimensional viewing space.

摘要： Embodiments of the present invention address deficiencies of the art in respect to screen reading non-sequential text and provide a method, system and computer program product for overlapping screen reading of non-sequential text, such as a tag cloud or Web page header. In an embodiment of the invention, an overlapping screen reading method for a non-sequential list of words can include computing different speech synthesis parameters for different words in a non-sequential list of words, generating different audio forms for each of the different words according to the different speech synthesis parameters, and overlappingly merging the generated different audio forms into a single audio stream. The speech synthesis parameters can include, for instance, separation, volume, tone and location speech synthesis parameters. Thereafter, the method can include playing back the single audio stream to simulate a natural visual scanning of the non-sequential list of words.
