A device for determining the teat positions of a dairy animal after milking. A first foot link and a second foot link are respectively connected to the crank arms for pivotal reciprocating movement. The adjustment circuitry includes conductors and programmable links, such as fuses or anti-fuses, in electrical communication with the die and the terminal contacts. One of those ribs is located along an axis of symmetry of the grid structure. A delayed task priority controller selects the delayed task with the highest priority in the queuing table. The series of addresses are derived from the received addresses.
