          Appeal No. 1999-0245                                                        
          Application No. 08/720,268                                                  

          of the claims on appeal, such that those skilled in the art of              
          ultrasonic fluid level sensing would be able to make and use the            
          claimed invention, i.e., the invention, as claimed, is enabled by           
          appellant’s disclosure.  The prior art background discussion in             
          appellant’s application, appellant’s description of the present             
          invention in the specification, and the incorporated in-depth               
          disclosure of Trudeau, collectively as a whole, convince us that            
          those having skill in the art of ultrasonic fluid level sensing             
          would be able to make and use the now claimed invention, without            
          having to undertake any undue experimentation.
