    • An acoustic position sensor 

      Dong, Shuxiang; Bai, Feiming; Li, Jiefang; Viehland, Dwight D. (AIP Publishing, 2003-11-01)
      This article presents an acoustic method-the resonance acoustic field sensor or piezoelectric-sound-resonance cavity (PSRC)-for object position detection. This method utilizes the change of acoustic radiation impedance as ...
    • Resonance acoustic field position sensor 

      Dong, Shuxiang; Bai, Feiming; Li, Jiefang; Viehland, Dwight D. (AIP Publishing, 2003-06-01)
      An acoustic position sensor, based on a piezoelectric-sound-resonance cavity (PSRC), is reported in which a resonance acoustic field is used as the sensing mechanism. It has been discovered that an inserted object or an ...
