  • Network Oscilloscope Using Packet Timestamps
    Publication number: 20190207830
    Abstract: A network oscilloscope, including a network interface configured to receive a stream of network data, one or more processors, and a display. The one or more processors generate a timestamp for each data packet parsed from the stream of network data, extract a portion of information from each of the data packets received from the stream of network data, the portion of information being less than an entirety of information in each data packet, and generate a data record indicating extracted information and a timestamp for each data packet parsed from the stream of network data. The display configured to display at least a portion of the data record.

  • System for generating text defined test patterns
    Patent number: 9723303
    Abstract: Embodiments of the invention are directed to a system for generating video test pattern signals from definitions contained in a text-based definition file. The definition file allows the user to create generic definitions for test signals that can be interpreted to create test signals in a variety of formats, raster sizes, color spaces, sample structures, frame modes, and bit depths. A parametric generator uses one or more engines to then generate the desired test pattern from the definition file.

  • Optical proximity correction in raster scan printing based on corner matching templates
    Patent number: 7529421
    Abstract: Methods and apparatus for correcting defects, such as rounded corners and line end shortening, in patterns formed via lithography are provided. Such defects are compensated for “post-rasterization” by manipulating the grayscale values of pixel maps.

  • Laser pattern imaging of circuit boards with grayscale image correction
    Publication number: 20020122109
    Abstract: An apparatus for registering a laser patterned image on a circuit board has a controller operating laser beam source, modulating and scanning components capable of generating, modulating and scanning one or more laser beams across a circuit board held on a support. The controller provides a data signal to the components, the data signal comprising a grayscale image bitmap comprising image pixels having grayscale levels that correspond to fractional beam intensities.
