Application No. 08/454,706
(supplemental answer, page 3) by asserting that Metroka shows
a voltage regulator circuit in col. 9, lines 38-50. We find
in the disclosure of Metroka (col. 9, lines 43-47) that
"[s]witching power supplies are well known per se in the art
and function to generate a constant voltage output responsive
to application of a wide range of voltages across an input
thereof." From this teaching of Metroka, we find that Metroka
discloses a voltage regulator circuit, as advanced by the
examiner.
Appellant responds to the examiner's finding of a voltage
regulator circuit in Metroka (reply brief, page 3) by
asserting that even if Metroka teaches or suggests a voltage
regulator circuit, that Barthel and Metroka do not teach or
suggest a series combination of a voltage regulator and a
detector device. We find that the examiner has not addressed
the limitation of a series combination of a voltage regulator
circuit and a detector device for detecting a current
corresponding to residual electrical power. We agree with
appellant (reply brief, page 3) that in Metroka, switching
power supply 400 is in parallel with five volt detector 406.
In the rejection, (final rejection, page 3) the examiner
