          Application No. 08/355,926                                                  


                                     BACKGROUND                                       
               The appellants' invention relates to a wide range                      
          temperature sensor (claims 1, 3, 4 and 6 through 10) and a                  
          method of sensing temperature within a broad range (claims 11               
          and 14).  An understanding of the invention can be derived                  
          from a reading of exemplary claims 1 and 11, which appear in                
          the appendix to the appellants' brief.                                      


               The prior art references of record relied upon by the                  
          examiner in rejecting the appealed claims are:
