  • Publication number: 20250005925
    Abstract: A novel multi-modal audio video framework is disclosed. The framework advantageously leverages both audio and video information to accurately detect whether the video has been manipulated, e.g., detect whether the video is a so-called ‘deepfake.’ In a video-only pipeline, the framework adopts a vision encoder having a feature extractor and a Transformer encoder that leverages self-attention mechanisms to detect artifacts in a facial region of the video. Additionally, in a separate audio-video pipeline, the framework adopts an audio+lip encoder having a Transformer encoder that leverages cross-attention mechanisms to identify discrepancies between lip movements of the person and words spoken by the person in the video. These two modalities are used jointly to make an inference as to whether the video has been manipulated.

  • Patent number: 12184106
    Abstract: Disclosed is a system and methods for measuring electrochemical state of rechargeable batteries such as state of charge (SoC) and state of health (SoH). In various aspects, the system may include an inductive coil attached to the battery and a battery current sensor. Alternating current with a fixed frequency is applied to the coil to generate magnetic fields, and the magnetic fields induce losses including Eddy current loss and a loss related to battery currents. The system compensates for the effect of the loss related to battery currents for battery electrochemical state estimation. In another aspect, the system uses both coil-based measurement and ampere hour counting (AHC) measurement for SoC measurement. The system conducts coil-based SoC measurement only occasionally to reset the accumulated error of AHC-based SoC measurement. In yet another aspect, the system combines coil-based measurement with other measurements.
