Appeal No. 2005-2615 3
Application No. 09/908,405
Clark Corp., 713 F.2d 760, 772, 218 USPQ 781 (Fed. Cir. 1983), cert. denied, 465 U.S.
1026 (1984).
The examiner’s findings in support of the rejection can be found on pages 2 and
3 of the final rejection.
Appellant argues, in regard to claim 1, that Peckels does not describe a serial
data jumper movable to a first position that inhibits the flow of serial communication data
beyond the volumetric module as required by claim 1.
The appellant’s specification discloses that volumetric modules 35, 36 etc. for a
drink dispenser are connected in series as depicted in Figure 2. Each module 35, 36 is
serially connected to the next module via a bus 30. The modules include serial data
jumper 39 which includes a single throw switch 40 with and interface 41 to one of the
I/O ports 38. In the address assignment of the present invention, all of the switches of
the each module is set to the open position. The system first determines whether there
is a non addressed module on the bus. As the switches are all open, the only module
that is on the bus is the first module 35 and therefore it is the only module which is non
addressed on the bus. The system then assigns an address to the first module and
closes the switch in the first module so that the second module is now on the bus. The
system then asks whether there are any non addressed modules on the bus and
because module one has received an address, the only non addressed module is the
second module. The system then assigns an address to the second module. In this
