          Appeal No. 1997-2289                                                        
          Application 08/395,691                                                      


               Now we analyze the two groups separately.                              
               Claims 1, 2 and 4 to 7                                                 
               These claims are rejected over Ganser and Stevens.  Take               
          claim 1 as illustrative.  We have reviewed Examiner’s position              
          [answer, pages 6, 7 and 9] and the Appellant’s position                     
          [brief, pages 6 to 8] and conclude that the Examiner has                    
          ignored some of the claimed limitations.  For example, neither              
          Ganser nor Stevens, singly or in combination, show the claimed              
          limitation, “the frequency of the alternating lamp current ...              
          remaining constant during a complete period of the AC power                 
          line voltage.” Therefore, we do not sustain the obviousness                 
          rejection of claim 1 and its dependent claims 2 and 4 to 7                  
          over Ganser and Stevens.                                                    
               Claims 3, 4, 6, 10, 14 and 15                                          
               These claims are rejected over Anderson and Stevens.                   
          They variously depend on independent claims 1, 8 and 12                     
          discussed above under 35 U.S.C.  102 over Anderson.  By                    
          virtue of their dependence on said independent claims, they                 
          each contain, besides other limitations, the claimed                        
          limitation, “the frequency of the alternating lamp current ...              


                                          9
