When the bottom-left cell is activated (touched), the loop self-replicates east-
ward in an eight-time-step process.
In the electronic watch application (Figure 1), the touch-sensitive element of
the BioWall cell acts as a push-button used to render the cell faulty or healthy
again. The LED display shows: the boundaries, the spare-cell columns, the cur-
rent time of each of its four digits, and the faulty or healthy state of the cell.
3 Design of a Life/Loop Automaton Cell
Defined in a two-dimensional cellular space, our automaton cell is made up of a
Life state machine, a loop state machine and a pseudo-random number generator.
The Life machine requires a nine-neighbor environment with two states,
Q
=
0 (dead) and
Q
= 1(living) per cell. The state
Q
+ of the machine at the next
