          Burgess et al. (Burgess) “Synthetic Vision - A View in the                  
          Fog,”IEEE Aerospace and Electronic Systems Magazine,”

               Claims 1-8 stand rejected under 35 U.S.C. 103 as

               Reference is made to the brief and answer for the                      
          respective                                                                  
          positions of appellants and the examiner.                                   

                                       OPINION                                        
               With regard to independent claims 1 and 2, the examiner                
          contends that since Burgess discloses a pilot viewing a runway              
          through a Head Mounted Display (HMD) and a second vision                    
          system, including radar or infrared sensors, is disclosed by                
          Burgess as generating a second visual output to the HMD for                 
          additional information, it would have been obvious to                       
          “communicate a first visual image having a first visual                     
          perspective and a first view angle to a second image having a               
          second visual perspective and second view angle in order to                 
          provide additional visual information to the user not available             
          from either view separately” [answer-pages 4-5].  Although the              
          examiner reasons that Diner is not even needed for the                      

                                          3
