Hi again,

yes i can use threads but, now i was wondering would a good idea to 
apply the Observer pattern in order to "fire" the other operations and 
keep going sampling data.

The samplings are UDP broadcast messages between many nodes and contain 
values gathered from sensors mounted in all nodes. All samples are the 
same, i want to collect it and after that operation create a bundle 
packages of collected data to another machine at regular intervals. All 
those nodes are into a local network. Sensor data are sent as Fixnum.

I hope to be clear enough to explain my problem, feel free to ask 
everything, because your questions give me the opportunity to rethink 
about it :)
