Appeal No. 96-0656
Application 08/099,277
a reference network that produces a plurality of reference network
voltages in response to the transformer reference voltage;
a reverse polarity detector circuit that determines if the battery voltage
is less than a first predetermined one of the reference network
voltages, thereby indicating at least one of the battery cells was
received in the battery receiving well with an incorrect electrical
polarity;
a battery type discriminating circuit that determines if the battery
voltage is greater than a second predetermined one of the reference
network voltages, thereby indicating at least one of the battery cells in
the receiving well is not a rechargeable battery cell; and
a charging circuit coupled to the transformer circuit and to the battery
cells that operates in a non-charging mode if the reverse polarity
detector circuit determines that at least one of the battery cells was
received in the battery receiving well with an incorrect polarity or if the
battery type discriminating circuit determines that at least one of the
battery cells is not a rechargeable battery cell and otherwise operates
in a charging mode for charging the battery cells.
The prior art references of record relied upon by the examiner in rejecting the
