          Appeal No. 96-0949                                                          
          Application 08/236,091                                                      


          we can find no reason that it would have been obvious to do so              
          within 35 U.S.C. § 103.                                                     
               In view of these findings, we are left without a teaching              
          reference to meet the limitations of representative                         
          independent claim 26 on appeal providing a means for detecting              
          and holding the peak analog output signals of the magnetic                  
          sensor during a time a threshold output signal is present and,              
          in addition, the subsequent comparing of this peak analog                   
          signal to a second predetermined value as both required by                  
          both independent claims on appeal.  None of the other two                   
          references relied upon teaches this feature.  Van Husen would               
          have been desirably combinable with the system of Laib since                
          Van Husen teaches testing Hall effect devices which are                     
          specifically utilized in the Laib system.  However, Van Husen               
          fails to teach or suggest the noted detection and holding of                
          peak analog signals and their comparison to a second                        
          predetermined value.                                                        
               Therefore, in view of the foregoing, the decision of the               
          examiner rejecting representative independent claim 26 on                   
          appeal is reversed.  Since the subject matter of independent                
          claim 21 tracks that of claim 26, the rejection of this claim               
                                          7
