It looks like a problem from real-time systems domain.
You may have some monitoring tasks running in an infinite
loop which read values from some device at constant time
intervals. Next, they may place the values in a buffer 
(think of using protected objects for that purpose). 
These tasks should not be blocked by accepting entries
or performing time-consuming operations (like console
I/O). Create also a task which will read the values 
from buffer and do something with them (for example
visualize them on the screen).

Happy tasking,
