Appeal No. 2000-0259
Application No. 08/827,835
Each receiver at each aisle is wired into a series of shelving
structures known as gondola units, each gondola unit being
controlled by a single controller or multiple controllers. Each
level of control beyond the receivers at each aisle redistributes
information to the next level down by selectively enabling the
receipt of message information at each subsequent level of
distribution. Each unit connected to a transmitting unit has the
message information transmitted to it, but only a unit that is
enabled to receive the message will logically have access to the
message. According to Appellant (specification, page 5), this
particular system arrangement eliminates wiring and hardware at
the display site which would otherwise be necessary for logical
address verification.
Claim 19 is illustrative of the invention and a copy of the
claim is appended to this decision.
