Appeal No. 96-0417 Page 2
Application No. 07/951,308
The appellants' invention relates to a method of
dispensing a fluid having a non-linear characteristic of flow
onto a work
piece in a controlled manner in response to a corrected
(linearized) compensated signal. According to appellants,
"[t]he invention provides for a more uniform bead size and
linear deposition rate of coating material, improved economy
of material, and improved quality of the coated product
(specification, page 8, lines 11-14). An understanding of the
invention can be derived from a reading of exemplary claims 33
and 43 (the only independent claims on appeal), which are
reproduced below.
33. A method of maintaining a controlled relationship
between a variable input signal and the actual dispensing rate
of a fluid having a non-linear characteristic of flow from a
dispensing device, the method comprising the steps of:
dispensing fluid from the device onto a workpiece by:
(1) receiving an input signal;
(2) modifying the received input signal as a
function of a measurement of a first flow of the fluid
from the device to produce a compensated signal;
(3) correcting the compensated signal with stored
correction data to generate a corrected compensated
signal to produce the actual dispensing rate having the
controlled relationship to the received input signal; and
