  • Publication number: 20040093662
    Abstract: A splash-prevention paper that is to be used in a toilet bowl to suppress the splash of soil water when the feces fall into the toilet bowl during the bowel movement. The splash-prevention paper of the present invention is a paper-like thin sheet. It may be folded or be in rolls for easy to handle before application. In the application, the splash-prevention paper floats on and covers the major portion of the water surface in the toilet bowl. It has plurality of floating arms, which allows the feces to pass, meanwhile, maintains an effective coverage of the water surface.

  • Patent number: 5943159
    Abstract: An optical beam steering device for steering a beam of light includes a first window having a common electrode, a second window having a plurality of control electrodes, and a layer of electro-optical material intermediate the first and second windows. The common electrode, the control electrodes, and the electro-optical material form an array of phase shifters within the optical array. Each phase shifter has a width substantially greater than a wavelength of the beam of light. Also included is a means for establishing an effective position of the phase shifters so that a single beam of light of peak intensity exits the optical array where the single beam of light is steerable through a predetermined angle.
