  • Publication number: 20210223679
    Abstract: A reflective mask includes a substrate, a reflective multilayer disposed on the substrate, a capping layer disposed on the reflective multilayer, and an absorber layer disposed on the capping layer. The absorber layer includes one or more alternating pairs of a first Cr based layer and a second Cr based layer different from the first Cr based layer.

  • Patent number: 8942571
    Abstract: In a light communication system, a data embedding unit arranged between a transmitter-side communication data processing unit and a light emitting device driver embeds a communication processed data at a spatial domain of an original image according to a modulation scheme, and gets multiple RGB values for a communication data embedded image. A receiving apparatus detects a transmitter-side communication data embedded image, generates a receiver-side communication data embedded image, compensate a deformation of the receiver-side communication data embedded image, outputs a warped communication data embedded image, and extracts a communication processed data from the warped communication data embedded image.

  • Patent number: 7522076
    Abstract: A method for performing parallel processing of at least two bins in an arithmetic coded bin stream includes: utilizing a current range to calculate a range for a first bin in the bin stream; simultaneously utilizing the current range to forward predict a plurality of possible ranges and low values for a second bin in the bin stream when the first bin is an MPS; when the range for the first bin is calculated, utilizing the calculated range to select a resultant range from the plurality of possible ranges and low values for the second bin.
