  • Patent number: 10733499
    Abstract: Embodiments are directed to identifying active compounds for a targeted medium from a library of compounds. In one scenario, a computer system receives high throughput screening (HTS) data for a subset of compounds that have been HTS-screened. The computer system determines labels for a subset of compounds based on labels identified in the HTS-screened compounds as being part of an active class or part of an inactive class, access chemical features corresponding to the HTS-screened compounds, apply Fuzzy logic membership functions to calculate membership values for active and inactive compounds to determine the degree to which each compound belongs to the active class or to the inactive class, train an artificial neural network (ANN) to identify active compounds in silico based on the Fuzzy logic membership functions, and process another subset of compounds in silico to identify active and inactive compounds using the trained artificial neural network.

  • Publication number: 20130135321
    Abstract: A three-dimensional display apparatus electromechanical system for displaying three-dimensional images without special viewing aids is disclosed. The electromechanical apparatus includes three flat surface screens, two rotating wheels or single screen not limited to other variations that will enable similar operation of the apparatus. The imaging system includes a CRT or similar device and control system to generate two-dimensional images to project the images at different depth locations through a focus system on to the moving projection screens.

  • Patent number: 6646623
    Abstract: A three-dimensional display apparatus (10) that can be used to display conventional pseudo three-dimensional images and true three dimensional images using a CRT screen (96), or an array of digital micromirror devices (152) or an array of activated micromirrors (174), or any other devices that can activate/deactivate multiple pixels, simultaneously, at a high speed.

  • Patent number: 6005608
    Abstract: A three-dimensional display apparatus (10) for displaying true three-dimensional images that can be viewed without special three-dimensional eye glasses is disclosed. The apparatus includes a screen (12), a screen moving assembly (14) for moving the screen to a selected number of depth locations, and an imaging assembly (16) for displaying images on the screen as it is moved to its different depth locations. The imaging assembly includes a CRT (80) for successively generating the two-dimensional images as the screen is moved, a focusing system (82) for focusing the images from the CRT to the screen, and a control system (84) for driving the CRT.

  • Patent number: 5717416
    Abstract: A display apparatus operable for displaying actual three-dimensional moving images is provided. The display apparatus includes a stepper motor having an elongated rotatable shaft, a plurality of display structures spaced along the length of the rotatable shaft, each of the display structures including a light-emitting element, and a control assembly for controlling the illumination of the light-emitting elements of the respective display structures for generating three-dimensional displays of moving images thereon.
