Appeal No. 1998-3072 Page 7 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 inPage: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
