Appeal No. 1996-3276
Application 07/978,518
Assocs., v. Garlock, Inc., 721 F.2d 1551, 1553, 220 USPQ 311,
312-13 (Fed. Cir. 1983).
Here, the Examiner uses Ihara, Matsuura and APA to make
the combination to meet the limitations of claim 1. We note
that Ihara is directed to a transmission line control system
which selectively connects and disconnects a communication
apparatus, Si, from the transmission line, L. The monitoring
devices W1 and W2, figure 3, monitor the power levels on lines
M1 and M2 and control the switches C1, C2, C3 and C4 to
connect or disconnect the communication apparatus from the
transmission line. Counters 17 and 21, figure 10, which form
a part of the monitoring device, help determine the length of
time during which a given power level is present on lines M1
and M2. Matsuura, on the other hand, discloses a pulse
detector for recovering data signals from a pulse-modulated
signal in an infrared remote control communication system.
Matsuura counts the pulses during different intervals of time
and compares the resulting number with a respective reference
number to distinguish the desired data signal from a noise
signal. Thus, we note that there is a concept of counting
