               Claims 1 to 4 and 9 to 11 stand finally rejected under                 
          35 U.S.C. § 103(a) as unpatentable over the following                       
          combination of references:                                                  
          (1) Labuhn or Deering, in view of Chakraborty;                              
          (2) Hibino ‘426 or ‘473, in view of Chakraborty.                            
               The Deering patent discloses an adaptive speed control                 
          system carried by a succeeding vehicle 10, traveling at the                 
          speed V  and acceleration A .  Preceding vehicle 10 is vehicleO                O                                                   
          12, traveling at speed V , at a range (distance from vehicle                
                                  T                                                   
          10) of RNG .  The system has two modes: mode 1, in which the                
                    A                                                                 
          actual range RNG  between the two vehicle is greater than a                 
                          A                                                           
          desired range RNG , and mode 2, in which RNG  is less thanD                        A
