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.

摘要： A sterilizing tray for holding objects while they are being sterilized in a sterilizing solution. At least one end of the sterilizing tray is equipped with a top pivoting end door whose latch can be released by tipping the end of the sterilizing tray against the work surface. Once the latch is released, the weight of sterilized objects in the tipped sterilizing tray pushes the end door open, thereby depositing the sterilized objects neatly on the work surface without their ever having been touched by the user.
