more than the battery current is sensed for determining the
operating point. It also does not appear that any of the
other applied references can cure this deficiency of Bavaro,
except, possibly, Frederick. Frederick does disclose a
control signal derived from a current sensor which senses the
output current which comprises a battery current and a load
current (See Figure 2 of Frederick). However, independent
claim 1 requires that the duty cycle of the pulse width
modulated switching power converter is controlled only in
accordance with the sensed output current. Frederick’s duty
cycle is controlled in accordance with the control signal 36
and the output voltage of the solar array. Since there is no
suggestion of doing away with the solar array output voltage
as a controlling factor, Frederick does not appear to aid in
providing for the deficiency of the other references regarding
the subject matter of instant claim 1. Thus, we will not
sustain the rejection of independent claim 1 under 35 U.S.C.
