  • Patent number: 10339024
    Abstract: A system for passive device identification includes a passive device communicatively coupled to a processing device. The processing device includes a passive device identifier configured to a current supplied to the passive electronic device at discrete intervals and to sample a voltage of the passive electronic device at each one of the discrete intervals to generate a dataset of current-voltage pairs. The passive define identifier is further configured to identify the passive electronic device based on the generated dataset.
    Type: Grant

  • Patent number: 9084002
    Abstract: A computer implemented method for synchronizing information from a scene using two heterogeneous sensing devices. Scene capture information is provided by a first sensor and a second sensor. The information comprises video streams including successive frames provided at different frequencies. Each frame is separated by a vertical blanking interval. A video output comprising a stream of successive frames each separated by a vertical blanking interval is rendered based on information in the scene. The method determines whether an adjustment of the first and second video stream relative to the video output stream is required by reference to the video output stream. A correction is then generated to at least one of said vertical blanking intervals.
