This is not a serious question, but it is driving me
crazy... I have opened the sldemo_househeat in matlab 2007a,
which models a house with heat equations. The demo works
perfectly, but I have found two new symbols in simulink,
that I have never seen before. On two simulink wires there
are two little blue symbols (like antennas), that I can not
understand what are. I have looked for those in help, but I
found nothing.

What are they?

Thank you
