  • Patent number: 11640824
    Abstract: Systems, devices, and methods transcribe words recorded in audio data. A computer-generated transcript is provided. The transcript comprises records for each word in the computer-generated transcript. At least one confirmation input is received for each record. The at least one confirmation input modifies a selected record and automatically identifies a next record for receiving a next confirmation input. A sequence of confirmation inputs may rapidly modify and validate each record in a sequence of records in the computer-generated transcript. A validated transcript is generated from the modified records and is provided from an evidence management system.
    Type: Grant
    Filed: July 15, 2020
    Date of Patent: May 2, 2023
    Assignee: Axon Enterprise, Inc.
    Inventors: Noah Spitzer-Williams, Choongyeun Cho, Thomas Crosley, Zachary Charles Goist, Daniel Michael Bellia, Vinh Hein Nguyen, Chelsea Alexander-Taylor

  • Patent number: 6723092
    Abstract: An RF treatment device according to the present invention includes one or two radio frequency electrode holders each having multiple electrodes arranged to create a transmural lesion through tissue. The treatment device is placed with one holder placed on the endocardial surface of the heart wall with the electrodes protruding towards the epicardial surface of the heart and the other optional holder placed on the epicardial surface of the heart with the electrodes protruding towards the endocardial surface of the heart forming a bipolar arrangement of equally spaced electrodes. The embodiments of the present invention are described for use in creating a transmural lesion in heart tissue to treat atrial fibrillation by blocking the passage of abnormal electrical currents through the heart. However, the devices and methods may also be used to create continuous transmural lesions in heart tissue and other body organs and tissues to treat other conditions.
