Car Radio with Traffic Monitor Feature

   This is an AM/FM car radio which is equipped with additional
features that scan for and save information about traffic
conditions before commuter starts their daily commute. There are
several steps the radio uses to accomplish this:

By monitoring the car's usage the (i.e. what time the power to

the radio is typically turned on in the morning) The radio can
know that our user typically drives to work at a specified time
and can know when to power up the radio's receiver prior to this
time. Or simply, the user can program what time the radio
should be powered up by itself, and which particular stations to
record the traffic information from.

After powering up the receiver the radio of this invention can

scan the broadcast using speech recognition technology for words
like: "Traffic", "Congestion", "Highway", "Interstate",
"Accident", "Slow", "North", "South", "East", "West", "Bound".
At the first occurrence of one of these words the radio starts to

save the audio in memory.
While threshold number of these words occur within short periods

of time, the radio assumes this to be a traffic related message
and continues to save it. (As an example consider the length of
the time period to be 7 seconds, and the threshold number of
words to be 4 for the initial period, and at least 3 of these
words in each subsequent period. When a period time is
encountered that contains less than 3 of these special words the
message is ended.)

Once the radio has found...
