Appeal No. 1998-0456 Page 11
Application No. 08/454,706
states that the five volt detector 406 is connected to the
switching power supply 400, but does not address whether they
are in series or parallel with each other. The portion of
Metroka referred to by the examiner (figure 9 and col. 9, line
60 et seq.) provides no disclosure or suggestion of connecting
the switching power supply 400 in series with the five volt
detector 406. In addition, appellant's argument that this
feature is missing from Metroka and Barthel has not been
addressed by the examiner.
In addition, we note that as asserted by appellant
(brief, page 5), Barthel discloses output capacitors 10 and 24
which are grounded to provide a stimulation pulse to the
atrium or ventricle of stimulable heart tissue. The output
capacitors 10 and 24 each have a value of approximately 10
microfarads.
We find that Barthel does disclose detecting the residual
voltage after the output capacitors have been discharged.
However, the residual voltage is detected as part of the
process of determining the energy of the stimulation pulse, in
which the voltage across the output capacitor is measured
directly before and immediately after the stimulation pulse
