tilt with other factors, such as elevation of a dump bin, to .

tilt and elevation reaches a tip over point.” (Appeal Br. at
6.) The examiner’s reply follows:
Kramer teaches that the sensor signals can also be
used as inputs to appropriate control units, see
column 8, lines 55+. It would have been obvious to
one of ordinary skill in the art at the time the
invention was made that in the case of dump bins an
‘appropriate control unit’ would control the dumping

signal. (Examiner’s Answer, ¶ 11.)
Claims 1, 3, 6, 7, 9, 10, 13, and 14 each specify “an
apparatus for measuring side-to-side tilt of a vehicle.” Each
of the claims adds that the vehicle has “a dump bin” and
“means for elevating one end of said dump bin.” Claims 1, 3,
6, 7, and 9 each further specify in pertinent part “means for
automatically stopping elevating of said bin when a
predetermined vehicle tilt limit is reached.” Similarly,
claims 10, 13, and 14 each further specify in pertinent part
“means . . . for stopping lifting of said bin end when vehicle
tilt reaches a predetermined angle.” In summary, claims 1, 3,
6, 7, 9, 10, 13, and 14 each recite measuring the side-to-side
