for providing a display of the patient’s cardiac and
respiratory activity (see page 3, lines 55-62 of the Fraden
specification). Thus, as far as claims 1 and 11 are
concerned, Fraden merely lacks an express disclosure of the
particular type of analyzing or monitoring device that
produces spectral peaks to represent the patient’s heartbeat
and respiration rates.
The Nedivi reference also discloses a method and
apparatus for monitoring a patient’s heartbeat and respiration
rates to indicate such conditions as apnea and cardiac failure
(see column 3, lines 41-47 of the Nedivi specification). In
Nedivi’s system a circuit B is responsive to piezoelectric
transducers to produce an analog voltage signal having
components representing the patient’s heartbeat and
respiration rates. The analog voltage signal is converted
into a digital signal by an analog-to-digital converter C, and
the resulting digital signal is processed by a Fourier
transform microprocessor F to recover and analyze the signal
components representing the patient’s heartbeat and
respiration rates (see column 3, lines 23-29 of the Nedivi
