The Burroughs et al. specification, column 4, lines 21
to lines 38, discloses the following embodiment:
In another embodiment of the present
invention, the battery-strength indicator means
comprises:
(a) a first nonconductive layer;
(b) a second nonconductive layer attached
to the first nonconductive layer, a portion of said
first and second nonconductive layers forming a
chamber therebetween;
(c) a conductive layer sandwiched between
said first and second nonconductive layers, the
conductive layer reduced to a small cross-sectional
area in the chamber; and
(d) a heat sensitive color-indicating
material in said sealed chamber that is adapted to
undergo a color change when its temperture [sic]
exceeds or crosses a predetermined value, said
conductive layer in the chamber rising to a
predetermined temperture [sic] when the voltage of
the current flowing therethrough exceeds a
predetermined value.
