24, “a profile of an induced armature voltage . . . electric
drive motor” refers to the voltage profile (as at “t ” in
ind
Fig. 2c) when no current is flowing through the motor, as
shown in Fig. 2b; this voltage “profile” varies as shown for
the three different “t ” time periods of Fig. 2c.

However, we do not consider claim 25's expression “a
profile of a current of said variable-speed electric drive
motor” to be definite. In the first place, this expression
does not define which current of the motor is being claimed,
nor does it define when the profile of the current is to be
measured (unlike the profile recited in claim 24). Secondly,
this expression becomes even more indefinite if one attempts
to read it in light of the specification, because as shown in
Fig. 2b, the motor current I is zero during the impulses, and
mot
thus has no “profile” at those times. On page 6 of the
specification, lines 6 to 13, appellants state that emitted
moment M can be calculated from I , but itab mot
is not clear how this can be done when the motor current is
zero during the time that there is an emitted moment (compare
Figs. 2b and 2d).
