  • Dynamic webcast content viewer method and system
    Patent number: 8037095
    Abstract: A data accessing method and system. The method includes receiving by a computing system from a first user, a first user profile comprising user preference data associated with the first user. The computing system receives and stores Webcast data associated with a Webcast that has been broadcasted for an entity. The Webcast data comprises audio/video data. The computing system receives from the first user, a first request for access to the first Webcast data. The computing system associates the user preference data with a first set of specified portions of the audio/video data. The computing system retrieves a first portion of audio/video data of the first set of specified portions of the audio/video data. The computing system presents the first portion of audio/video data to the first user.

  • Characterization of radio frequency (RF) signals using wavelet-based parameter extraction
    Patent number: 7340381
    Abstract: Embodiments of the present invention apply wavelets to radio frequency (RF) signals to extract specific characteristics (e.g., jitter, phase variations, frequency variations) so that their timing, phase, and frequency components can be characterized. In one embodiment of the present invention, a Haar wavelet is used to extract timing characteristics. In another embodiment, a Morlet wavelet is used to extract phase characteristics. In still another embodiment, a Morlet wavelet is used to extract frequency characteristics.
