Appeal No. 2000-1526 Application No. 08/902,196 eventually, converting the electric signals into acoustic signals which can then be used in a conventional acoustic hearing aid testing device. The examiner employs Marutake for a showing, on the upper cover figure, of a conversion of magnetic signals to electric (25) and then from electric to acoustic (20) via a processor (12). Realizing that Marutake lacks a magnetic drive unit, the examiner turns to Beaty for a showing of a magnetic drive unit, comprising coil 14, cable 15 and receiver 12. The examiner concludes, with no apparent support, that it would have been obvious to combine these teachings “in order to provide a strong magnetic source and to overcome feedback or distortion problems of conventional hearing aid devices” [answer-page 5]. Even so, the examiner acknowledges that the combination of Marutake and Beaty still lacks a testing apparatus comprising a magnetic-to-acoustic transducer for testing a magnetic hearing device. Therefore, the examiner cites Frye for a testing device and concludes that it would have been obvious to combine this testing device with the magnetic-to-acoustic transducer of Marutake and the magnetic drive of Beaty “in order to adjust hearing aid devices to optimum default settings regarding the frequency response, amplitude response, etc. before sending them out to hearing aid providers” [answer-page 5]. 7Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
