  • Patent number: 11064149
    Abstract: Provided are systems and methods for integrating encoded identifiers (e.g., Quick Response (“QR”) codes) with changing arrangements into different video frames of a video in a manner that blends the encoded identifiers with the pixels, coloring, and/or pattern of the video frames and that allows a particular message to be decoded from each encoded identifier. The blended integration of encoded identifiers may include clustering a first set of images from a video based on an amount of variation in the first set of images, determining visual properties for pixels at a particular location within the first set of images, generating an identifier as a two-dimensional pattern with different colored blocks that encode a particular message using coloring that is derived from the visual properties for the pixels at the particular location, and integrating the identifier into the first set of images at the particular location.

  • Patent number: 9927234
    Abstract: A position-measuring device includes a module configured to vary a signal period of a position-dependent sinusoidal analog scanning signal. A conversion unit is configured to receive the sinusoidal analog scanning signal and to generate therefrom a sinusoidal digital output signal having a varied signal period compared to the sinusoidal analog scanning signal. A digital-to-analog converter is configured to generate, from the sinusoidal digital output signal, a sinusoidal analog output signal having a varied signal period. The conversion unit is configured to change an operating mode in dependence upon a frequency of the sinusoidal analog scanning signal in such a way that in a case of higher frequencies of the sinusoidal analog scanning signal, the sinusoidal digital output signal is fed to the digital-to-analog converter at a higher output rate and with a smaller word width than in a case of lower frequencies of the sinusoidal analog scanning signal.

  • Publication number: 20040111174
    Abstract: Method and subsystem are provided for determining a sequence in which microstructures are to be processed at a laser-processing site by taking into account microstructures located near travel limits of a motor-driven stage. The method includes receiving reference data which represent locations of microstructures to be processed at the site and coalescing adjacent groups of microstructures into clusters of microstructures including edge clusters which contain the microstructures located near the travel limits of the motor-driven stage which moves the microstructures relative to a laser beam at the site. The method also includes dividing a cluster fragment from each edge cluster. The cluster fragments contain the microstructures located near the travel limits. The method then includes sorting the clusters and cluster fragments to obtain data which represent a substantially optimum sequence in which the microstructures are to be processed to increase throughput at the site.
