  • Patent number: 11112635
    Abstract: A display apparatus includes a frame case to support four sides of a display panel. The frame case is formed by bending a bar-shaped member made of a metal into a rectangular ring shape. Opposite ends of the bar-shaped member facing each other are covered by a cover member, which prevents quality degradation of the appearance of the display.

  • Publication number: 20210245296
    Abstract: The present disclosure relates to a system for laser processing of a ceramic electrolyte material. The system may include a controller, a laser responsive to the controller for generating a beam, and a beam forming subsystem. The beam forming subsystem controls a parameter of the beam generated by the laser. The beam forming subsystem further controls the beam to provide a laser fluence sufficient to produce densification of the ceramic electrolyte material.

  • Publication number: 20200371044
    Abstract: An optical inspection system for detecting sub-micron features on a sample component. The system may have a controller, a camera responsive to the controller for capturing images, an objective lens able to capture submicron scale features on the sample component, and a pulsed light source. The pulsed light source may be used to generate light pulses. The camera may be controlled to acquire images, using the objective lens, only while the pulsed light source is providing light pulses illuminating a portion of the sample component. Relative movement between the sample component and the objective lens is provided to enable at least one of a desired subportion or an entirety of the sample component to be scanned with the camera.

  • Publication number: 20190391298
    Abstract: A system and method is disclosed for forming a graded index (GRIN) on a substrate. In one implementation the method may involve applying a metal layer to the substrate. A fluence profile of optical energy applied to the metal layer may be controlled to substantially ablate the metal layer to create a vaporized metal layer. The fluence profile may be further controlled to control a size of metal nanoparticles created from the vaporized metal layer as the vaporized metal layer condenses and forms metal nanoparticles, the metal nanoparticles being deposited back on the substrate to form a GRIN surface on the substrate.

  • Publication number: 20190291210
    Abstract: The present disclosure relates to a method of modifying a surface of a material, in situ, while the material is being used to at least one of form or modify a portion of a part to remove flaws layer-by-layer and improve a part from a layerwise built, or a coating. The method may involve generating first, second and third beams. The third beam may act on a surface of a material to heat a portion of the surface of the material into a flowable state to thus modify a surface characteristic of the material. The first beam may control an optically addressable light valve (OALV) which modifies an energy of the third beam. The second beam may control an optically addressable electric field modulator (OAEFM) to generate an electric field in a vicinity of the surface and to influence a movement of the portion of material while the portion of material is in the flowable state. The beams are modulated based on a sensing element feedback loop.

  • Patent number: 7809878
    Abstract: Provided are an apparatus and method for controlling a flash memory, more particularly, an apparatus and method for controlling flash memory that updates control information of a flash memory stored in a predetermined volatile memory when the type of flash memory is changed and controls the changed flash memory using the updated control information. The apparatus includes a flash memory storing its own control information, a first memory storing a programming code for controlling the flash memory, a control unit generating a control code for controlling the flash memory by assigning the control information to the programming code, and a transceiver transmitting the control code.

  • Patent number: 7573754
    Abstract: A nonvolatile memory including a memory cell that stores data in a plurality of pages included in a block according to a voltage applied to a memory cell is provided. The nonvolatile memory includes a block that includes a first page including first data that stores data recorded by a user, and a second page including second data area that stores data recorded by a user, wherein the second page records count-information on states represented by a bit pair in the same position of the first data area and the second data area.
