Appeal No. 96-2995
Application 08/383,608
vehicle control and safety." [answer, page 4].
The appellant argues that there is no teaching in the
cited references of Kawana, Bazille or Rakos that would lead
one to substitute the switch of Rakos into the system of
Kawana [brief, page 12].
The Examiner responds that Kawana teaches activation of
the playback device by the grip of the bus driver. The
Examiner further takes an official notice of the fact that "it
is also conventional in the aircraft art [vehicle art] to
include a radio push-to-talk switch on the steering yoke so
that a pilot does not have to remove hands from the steering
device [yoke] to perform [activate] non-steering functions"
[answer, page 5].
We note that Kawana does suggest the desirability of
activating the message playback system without removing the
hand from the steering wheel, simply by "the grip of a bus
driver" [English abstract]. We also note that Appellant has
not contested, by any reply brief, the Examiner's taking of
official notice of the use of a no-hands-required switch to
perform non-steering functions while steering an aircraft
[vehicle].
