Appeal No. 2000-1481 Page 7
Application No. 08/950,130
claimed invention since the improvement clause of claim 1 is 2
not taught or suggested by Cook.
For the reasons set forth above, the decision of the
examiner to reject claim 1, and claim 2 dependent thereon,
under 35 U.S.C. § 103 is reversed.
2Claim 1 reads as follows:
In an antiskid control system for a multigain
hydraulic brake system that includes a multigain antiskid
hydraulic valve, an integral-based pressure bias
modulation control algorithm for producing an antiskid
control current for application to said multigain
antiskid hydraulic valve, and a pressure bias modulation
high step current that overrides the antiskid control
current when the antiskid control current exceeds a
pressure bias modulation threshold, the improvement
comprising dual pressure bias modulation thresholds, one
threshold being active at low wheelspeeds and the other
being active at high wheelspeeds.
