Appeal No. 2004-1553
Application No. 09/915,631
Claim 19, the only other independent claim on appeal, is
directed to a system for controlling the damping characteristics
of a motor vehicle powertrain mount comprising, among other
things, a first positively charged plate “fixed relative to” one
of the powertrain component or the frame of the motor vehicle,
and a second, negatively charged plate “fixed relative to” the
other of the powertrain component or the frame of the motor
vehicle.
Yamakado, the alleged anticipatory reference, is directed,
in pertinent part, to mounting devices for mounting a vehicle
engine to a chassis wherein the mounting devices are controlled
in dependence on the differential of acceleration of the engine,
thereby to smooth the transmission of power from the engine
(column 2, lines 54-60). With reference to Figure 17, a sensor
163 for measuring the differential of acceleration is mounted on
an engine 161, the engine being supported by engine mounts 162a
and 162b. The acceleration differential sensor 163 supplies a
signal to a controller 167 which in turn controls the engine
mounts 162a, 162b, presumably by changing the damping
characteristics of the mounts. Figure 4 shows the configuration
of a first embodiment of an acceleration differential sensor that
may be used in the system of Figure 17. The Figure 4 sensor
