  • METHOD AND APPARATUS FOR TUNING SCAN CAPTURE PHASE ACTIVITY FACTOR
    Publication number: 20140181603
    Abstract: A method and apparatus for tuning the activity factor of a scan capture phase is described. In one example an activity factor is determined for a die to be tested. The die may be isolated or part of a wafer. A structural scan test is modified to run with an activity factor based on the determined activity factor. The modified structural scan test is run and the die is characterized based on the test.

  • Voice responsive audio system
    Patent number: 6766290
    Abstract: An audio/video system may generate audio data for a user. The user in turn may provide voice commands to the audio/video system. The audio generated by the system may be adaptively delayed, amplitude adjusted, and subjected to sampling interval shifting before subtracting it from the composite signal received from a microphone. As a result, the audio generated by the system can be subtracted from a signal representing both the audio generated and the spoken command to facilitate the recognition of the spoken command. In this way, a voice responsive audio/video system may be implemented.
