Appeal No. 95-2730
Application No. 08/169959
Thus, the two modes of operations merely involve the
measuring of the relative speed of an object vis á vis a
vehicle and the determination of the position/direction of
that object, i.e., standing still, moving in the same
direction but slower than the vehicle or coming at the
vehicle. The skilled artisan was aware of how to make such
determinations from the prior art at the time of filing the
instant application.
The claimed subject matter merely involves a combination
of these two modes wherein the mode is selectable. It would
appear unreasonable to assume that the skilled artisan would
have needed to resort to anything more than routine
experimentation in order to practice the instant claimed
invention whereby one may switch between the two modes of
operation. The skilled artisan certainly could have employed
a switch or some logic circuitry,
including, for example, AND/or NOR gates, in a routine manner
to implement the selection between the first and second
operating modes.
Accordingly, in view of the rather simple functions to be
performed and the availability of prior art devices for
