Appeal No. 1998-2375
Application 08/512,065
the sensor detecting motion of the motor vehicle indicates that the motion sensor senses
the number of revolutions of the wheels to determine a distance value. How this is
accomplished is discussed in detail regarding Figure 4 beginning at column 6, line 35. An
alternative embodiment shown in Figure 5 is discussed in the initial lines of column 7
enabling the device shown in Figure 5 to determine distance and time of the vehicle
movement.
As noted at column 8, at lines 41 through 45, in the embodiment shown in Figure 6
“the pulse train is developed not by directly measuring the motion of the drive train but by
sensing acceleration with an accelerometer.” The discussion of Figure 6 itself begins at
column 7, line 32. The discussion ending at line 43 indicates that (and this is shown at
Figure 6 itself) the output of the accelerometer ACL is integrated once to produce a
voltage proportional to velocity. This voltage is then applied to the VCO to produce a
frequency proportional to velocity. This voltage output from the VCO as stated at lines 40
and 41 “can be used to produce pulses that are equivalent to rotation of the vehicle wheel.”
There is no further discussion in the reference apparently dealing with this velocity
determination. However, Figure 6 shows that the output of the VCO on line 20 would
therefore be fed into the counter CTR of Figure 4. Thus, it is apparent to us that the output
pulses of the VCO embodiment in Figure 6 would be a velocity determination, which
pulses are counted by the counter in Figure 4. We, therefore, disagree with appellants'
