  • Patent number: 11146902
    Abstract: A device may receive a request to initiate an audio test and may generate, based on the request, one or more instructions to control a bone transducer device and a microphone device. The device may send the one or more instructions to a control device and may receive, after sending the one or more instructions, audio data from the control device. The device may process the audio data to determine whether the audio data includes an otoacoustic emission (OAE) and may cause at least one action to be performed based on determining whether the OAE is included in the audio data.
    Type: Grant
    Filed: August 29, 2019
    Date of Patent: October 12, 2021
    Assignee: THE JOHNS HOPKINS UNIVERSITY
    Inventors: Aseem Jain, Gianluca Croso, Sanjay Elangovan, Andrew Sean Tsai, Richard J. Chen, Taha Mirza Baig, Gavin Mischler, Adarsha Malla, Darian Low, Francis Xavier Creighton

  • Publication number: 20040232951
    Abstract: A detector circuit for determining whether synchronization lock has been optimally achieved in feedback-type control systems. The detector circuit evaluates an error signal developed by a phase/frequency detector and compares the absolute magnitude of the error signal to a first threshold signal corresponding to a magnitude metric. When the value of the error signal is less than the magnitude threshold value, an event signal initiates a time interval counter which continues counting so long as the error signal remains below the magnitude threshold value. The time interval counter continues until it counts to a second threshold value corresponding to a timing metric. At this point, synchronization lock is declared.
