          Appeal No. 1997-0202                                                         
          Application No. 08/247,709                                                   


          Answer to remain unrebutted by any convincing arguments of                   
          Appellants.  We note that even in Appellants’ interpretation of              
          Ehrlich (Brief, page 24), i.e., the system resets each time the              
          ignition is turned on, the claim 3 limitations would be met.  As             
          to claims 4 and 5 we find the Examiner’s reasoning that Ehrlich’s            
          rate of blinking corresponds to attainment of a predetermined                
          threshold level convincing as well.                                          
               With respect to dependent claim 35, which is presently                  
          dependent on canceled claim 1, both Appellants and the Examiner              
          have treated this claim as being properly dependent on claim 392.            
          We will do so as well and also sustain the Examiner’s obviousness            
          rejection of this claim.  We find the Examiner’s reasoning to be             
          convincing to the extent that the spurious signals that are                  
          desired to be eliminated by Ehrlich (column 13, lines 58-68)                 
          would obviously include such potentially signal degrading sources            
          such as drift and component aging.                                           



               2 Appellants attempted to correct the dependency of claim 35            
          to depend from claim 39 rather than canceled claim 1 in the                  
          amendment after final rejection filed February 16, 1996.  Such               
          amendment, however, was denied entry by the Examiner.  At page 6             
          of the Brief, Appellants make reference to a second proposed                 
          amendment after final which presumably again attempted to correct            
          the dependency of claim 39.  This proposed amendment has not been            
          found associated with the application file.                                  
                                          13
