Appeal No. 2002-1798
Application 09/238,804
BACKGROUND
The invention relates to a vehicle speed measuring and
display device that displays an approaching vehicle's speed on a
digital display at a subdued, steady state when the speed is
under the legal speed limit and at a highly visible, warning
state when the speed is above the legal speed limit. The warning
state may be provided by flashing or an accentuating color.2
Claim 31 is reproduced below.
31. A vehicle speed measuring and display device
comprising:
a mobile display structure adapted to be positioned at a
roadside location where it can be seen by a driver of
an approaching vehicle,
means for providing a signal indicative of the actual speed
of a vehicle approaching said structure,
means on said structure responsive to said signal for
displaying said vehicle's speed in a digital form, said
display means having electrically responsive indicia
2 It is noted that many companies manufacture radar speed
monitors with a speed alarm option that flashes the speed when
the speed limit is exceeded, e.g., MPH Industries
(wwww.mphindustries.com/products_home/monitor_trailers2.html),
Traffic Display Monitor Co. (1-radar-speed-trailer-
display.com/feature.htm), McCoy's Lawline
(www.policeradar.com/RadarTrailer2.htm). These were found with a
Google search using "radar speed displays." However, the date
these devices were first made is unknown and appellants have an
effective filing date of September 18, 1997. Since it is known
that many commercial devices will infringe any patent that may
issue on this application, it is in the best interests of both
the public and appellants to have the best possible rejection
made in the first instance.
