Appeal No. 2006-2284 Page 2
Application No. 09/912,211
Accordingly, the appellants' invention transmits a signal toward a region of
interest. Upon receiving energy reflected from the region, the invention establishes a
baseline field strength for the energy. It then determines at least one frequency at
which the field strength substantially differs from the baseline and identifies at least one
object within the region based on the determined frequency. (Id. at 3.)
A further understanding of the invention can be achieved by reading the following
claims.
23. A container comprising:
object presence detection equipment internal to said container, said
equipment comprising at least one transmitter of transmitted signal energy
and a plurality of fixed receivers of received signal energy;
a set of objects for object presence detection internal to said
container, such that an object of said set of objects is operable to modify
said transmitted signal energy of a selected frequency to generate said
received signal energy of said selected frequency, wherein said set of
objects is disposed in a configuration selected from a linear array, a two-
dimensional array, and a three-dimensional array; and
a container wall substantially surrounding said object presence
detection equipment and said set of objects, said wall operable to shield
said equipment and said set of objects from extraneous external signals.
