  • Patent number: 10474101
    Abstract: A method and system for recycling signals in a leaky mode device for a holographic display or other application. A leaky mode device comprises at least a first transducer, a substrate, and a second transducer. The first transducer may be configured to receive an input signal from a signal arbiter, which forwards to the first transducer as an input signal either a new input signal or a recycled input signal (or some combination of the two). The first transducer converts the received input signal to a SAW (surface acoustic wave) and transmits the SAW through the substrate to the second transducer, which converts the received SAW to an output signal, and forwards the output signal to an amplifier, which amplifies the output signal (now a “recycled” signal) and forwards to the signal arbiter. This system facilitates persistence for points in a holographic display without the need for continually rewriting to leaky mode devices.

  • Patent number: 10465861
    Abstract: A light source is realized in a wall portion and a base portion forming a flexible structure, a the wall portion having a plurality of inward facing LEDs thereupon, a bottom edge of the wall portion being adjacent to an edge of the wide portion. The resulting well is subsequently filled with a material to form an optical cavity, the height of the resultant optical cavity being matching a top edge of the wall portion. The top surface of the optical cavity is spin coated with a thin layer of quantum dots which serve to shift a wavelength of light emitted from the LEDs. Finally, a protective layer is applied to fix and protect the thin layer of quantum dots. Thus, a light source is realized which can reliably provide light at a specific wavelength defined by the interaction between the LEDs and quantum dots.

  • Patent number: 10450227
    Abstract: A method is provided for producing a raised feature on a glass ceramic element, in which a glass or glass ceramic element is irradiated with electromagnetic radiation in a local region of the surface, the radiation passes through the element and is at least partially absorbed thereby so that the element heats up in the region of the irradiated electromagnetic radiation and is heated beyond a glass transition temperature. The irradiation is terminated after heating so that the heated region cools down to the temperature of material surrounding the local region. The heating causes a change in volume of the element, which brings about a local elevation in the surface that remains after the local region cools so that a surface deformation in the form of an elevation remains after cooling.
