          Application No. 08/769,610                                                  


          illustrate these sections within the pulses.  The commutation               
          of the motor coils is further controlled at these points by                 
          reducing the current as is common within motor commutation.                 
          Figure 6 within Plunkett illustrates the actual pulse shapes                
          within the coils ...."  (Examiner's Answer at 8.)  He adds,                 
          "[t]he hall effect detectors within Ohi and Plunkett clearly                
          operate the commutation based on these 'detected' pulses                    
          within the motor coils."  (Id. at 8.)                                       


               Claims 1-5, 7-14, and 76 specify in pertinent part the                 
          following limitations: "said control circuit determining                    
          periods of reduced magnetic coupling between the rotor and                  
          stator during the cycle of applied power and inhibiting the                 
          supply of power to said at least one winding during the                     
          determined periods of reduced magnetic coupling ...."                       
          Similarly, claims 23-25, 33, and 34 specify in pertinent part               
          the following limitations: "the control circuit to determine                
          periods of lower rotational torque during the cycle of applied              
          power ... and for inhibiting the supply of power to the at                  
          least one winding during the determined periods of lower                    
          rotational torque ...."  Similarly, claim 75 specifies in
