  • System, method, and computer program product for parsing packetized, multi-program transport stream
    Patent number: 7349395
    Abstract: Systems, methods, and computer program products for parsing a packetized, multi-program transport stream are disclosed. A packetized, multi-program transport stream is received in a demultiplexer. Program specific information is extracted from the program stream and displayed on a user interface. A user may select a program from the program stream for further processing. The user interface generates a signal indicative of the selected program, and the demultiplexer output is configured based on the selection signal.

  • Wafer edge inspection and metrology
    Publication number: 20080013822
    Abstract: Some aspects of the present invention relate to a wafer inspection method. A plurality of images is acquired about an edge portion of a wafer. Each of the images comprises a pixel array having a first dimension and a second dimension. A composite image of compressed pixel arrays is generated by compressing each of the pixel arrays in the first dimension and concatenating the pixel arrays. The composite image is analyzed to identify a wafer feature, for example using a sinusoidal line fit.

  • Systems and methods for monitoring object activity through an external agent using a proxy object
    Patent number: 6892326
    Abstract: Systems and methods are described for monitoring the activity of an object to aid in debugging a problem with an application using the object. An operating system registry is altered to reference a proxy object when the application attempts to reference the object. The proxy object exposes an interface exposed by the object. Communications passing between the application and the object can be monitored in the proxy object. The proxy object can be monitored locally or remotely through a remote procedure channel.
