Hyphens are for spacing and all numbers are positive.

The values comes from a sensor that records the cardinals points. They are voltage levels expressed as 2 powers.(2^x) Actually, they are binary signals, with only two possible states. The high state is for 2,(a binary 1) and the low state for 768 ( a binary 0).

The numbers don´t show any other kind of information. That means that when you have

for t=0.1 768 768 768 2 (0 0 0 1)the direction is westward.

Also you can have two activated columns,i.e, 2 2 768 768 (1 1 0 0) the direction is north-eastward.

So I´ve got 4 binary signals changing with time. And only one or maximum two adjacent channels are activated every 0.1s.
