  • Patent number: 11989495
    Abstract: A method includes obtaining sensor data associated with a deposition process performed in a process chamber to deposit film on a surface of a substrate. The method further includes generating a plurality of physics based outputs using a transformation function and the sensor data. The method further includes mapping the physics based outputs to a training set. The method further includes training a virtual model based on the training set and the sensor data, wherein the virtual model is trained to generate predictive metrology data associated with the film.

  • Patent number: 7167640
    Abstract: A dynamic allocation of available ASV buffer memory space is performed on each pack in a DVD-A bitstream one pack at a time. Concurrently, an ASV buffer table is updated for each type of data pack currently being processed. The ASV buffer table includes pointers corresponding to the various fields that form a particular ASV frame. In this way, only that memory that is required to store a particular ASV frame is used thereby allowing the ASV buffer memory to be configured on the fly in such a manner as to efficiently store the required ASV frame data. When a particular ASV frame is to be displayed, or otherwise processed, the ASV buffer table is accessed, and the particular pointers for a specific ASV frame are looked up and used to access the desired ASV frame.

  • Patent number: 7099569
    Abstract: When switching between a DVD-video mode and a DVD-audio mode in a DVD-A/V player, a current video frame is stored in a current display buffer portion of the memory during the DVD-video mode. The DVD-A/V player is paused in the DVD-video mode and set in the DVD-audio mode. If it is determined that the current display buffer portion of the memory is a reserved display buffer portion of the memory, then the current video frame is copied to a reconstructed display buffer portion of the memory. At least the current display portion of the memory is designated as an ASV buffer and a frame buffer management scheme is changed so as to preserve the ASV buffer.
