  • Systems and methods for tracking impacts
    Patent number: 7916128
    Abstract: Surface impacts are located and characterized based on an acoustic signal produced by the impact despite the presence of signal dispersion. Acoustic signals from the surface may be compared to acoustic signals detected external to the surface in order to eliminate spurious impact sensing due to external sounds. Low-frequency acoustic signals may be sensed and identified as explicit hard “bangs” which are of limited utility for pointing and tracking applications.
    Type: Grant
    Filed: January 4, 2010
    Date of Patent: March 29, 2011
    Assignee: Massachusetts Institute of Technology
    Inventors: Joseph A. Paradiso, Che King Leo, Nisha Checka
