way each of the modules is successively assigned an address. Because the preceding
module’s switch is open when a module is being addressed communication to that
module is possible. However, because the switch in the serial jumper of the module
being addressed is open, communication on the bus beyond the module being
addressed is inhibited.
Peckels describes a electronic dispensing system which includes a plurality of
heads 12 which when attached to bottles 14 control the dispensing of liquid (Fig. 1).
The heads are all in communication via antenna 16 to an on site dispensing center 22
(Figure 1; col. 7, lines 37 to 41). Peckels describes an address assignment process at
column 18, lies 3 to 24. In Peckels' address assignment process a head 12 is mounted
on a bottle 14 and thus the adjoined head and bottle are brought into operative
proximity with charging coil 162 or interrogator 25 and bar code reader 23. The bar
code reader 23 reads the bar code on the bottle 14 and an identification bar code on
the head 12 and supplies this information to the computer 24. The computer 24 then
assigns an identification number to the head and correlates the identification number
with the product in the specific bottle. Peckels discloses that:
With this . . . system 10A, the heads 12 no longer need a dedicated I.D.
number; the heads 12 will be supplied with a relative "zero" out on the
encoder 174A ane the computer will electronically set the encoder 174A
upon loading the head on the bottle 14(col. 18, lines 19 to 24).
Firstly, as the heads are connected in parallel, there is no serial communication
described in Peckels. In addition, as the computer sets the encoder 174A, after
