          Appeal No. 2001-0250                                      Page 22           
          Application No. 08/283,074                                                  


          output signal is not described in the Seybert et al                         
          reference."  (Appeal Br. at 10.)                                            


               Claim 15 specifies in pertinent part the following                     
          limitations: "a processor means coupled to said plurality of                
          pressure-wave-sensing transducers including means for                       
          processing said first and second transduced signals in                      
          accordance with an algorithm that takes into account said                   
          first wave and said second wave to provide said output signal               
          characteristic of said confined volume geometry."  Similarly,               
          claim 16 specifies in pertinent part the following                          
          limitations: "processing said first and second transduced                   
          signals in accordance with an algorithm that takes into                     
          account said first wave and said second wave to provide an                  
          output signal representative of a characteristic of said                    
          confined volume."  Giving claims 15 and 16 their broadest                   
          reasonable interpretation, the limitations merely recite                    
          producing a signal representing the cross-sectional area of a               
          confined volume.
