Appeal No. 96-3156
Application 08/304,333
5, 1996, has been entered. See page 2 of the supplemental
examiner’s answer (Paper No. 25).
THE INVENTION
Appellants’ invention pertains to a fluid brake system for
vehicles. As explained on page 2-3 of the brief (Paper No. 13):
Appellants’ invention provides a brake system (10)
that enables using only one solenoid valve per control
wheel brake (Fig. 1). The invention provides a first
mode for default base brake operation that provides a
direct connection between the unboosted master cylinder
(22) and the wheel brakes (12, 14, 16, 18). The
invention provides a second mode for all power brake
operation that maintains an open flow path between
master cylinder (22) and an artificial pedal feel
device (30, 32) while automatically modulating braking
pressure at each wheel brake independently through the
use of an individual valve (52, 54, 56, 58) per wheel.
Each valve is responsive to pressurization of the
system through manual actuation of the master cylinder
and additionally, to electronic control in response to
wheel sensor readings falling within various
preprogrammed events.
The operation of appellants’ invention is further explained
on pages 3-5 of the brief.
THE CLAIMS
Independent claim 4, a copy of which is appended to
appellants’ brief, is representative of the appealed subject
matter.
Independent claims 4 and 10 define a brake system that
includes a valve which in one mode or position provides fluid
