time. See appellants’ specification at page 1, lines 25-27, page
2, lines 15-24, page 3, lines 8 and 9, page 6, lines 27 and 28,
and page 7, line 29, to page 8, line 13. At column 3, lines 26-
35, Cameron teaches that sense cell 22 (Figure 2) is depleted
faster than main battery 10. Accordingly, during periods of use
when depletion occurs in the batteries and cells, sense cell 22
has a second charge-storage capacity that is less than the
charge-storage capacity of main battery 10- -which may be a
single cell 20- -because sense cell 22 is depleted faster than
main battery 10. See column 2, line 66, to column 3, line 77 of
Cameron for the teaching that battery 10 may be a single cell,
and column 3, lines 26-35, for the teaching that sense cell 22 is
depleted faster than main battery 10.
As to claims 4, 6, 7, 21, 22 and 34-38, at column 4, lines
29-36, Cameron teaches a rechargeable battery as a sense cell
starting from a depleted condition when the main battery is fully
charged. In this embodiment, a sense battery cell stores a
second, depleted charge smaller than the first, full charge on
the main battery cell before the main battery cell first
discharges through the load.
