Abstract
Abstract A transponder scanner for scanning a passive transponder within a high noise environment has a housing. A ferrite rod is positioned within the housing. A high gauge thin wire is wound about the ferrite rod to form a magnetic coil so that adjacent coils of the magnetic coil are separated by a distance much greater than the diameter of the magnetic wire. A CPU receives the scanned signal corresponding to a preprogrammed code and an in house generated code and maps the preprogrammed code to the in house generated code.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
A scanner for use in scanning passive transponders utilizing an LC circuit comprising a housing; antenna means for transmitting and receiving a signal including a ferrite rod supported within said housing, a magnetic coil defined by a wire wound about said ferrite rod to form a plurality of coils, the antenna means receiving a preprogrammed ID number from said scanned transponder; input means for generating a user selected in house ID number; mapping means for generating an in house ID number in response to said input means and for mapping said preprogrammed ID number to said in house ID number to form a mapped pair; display means for receiving said in house generated ID number and displaying said in house ID number; and processing means for processing said in house ID number when data representative of said preprogrammed ID number is received.
Claim 2
Dependent Claim
142 words
A scanner for use in scanning passive transponders utilizing an LC circuit comprising a housing; antenna means for transmitting and receiving a signal including a ferrite rod supported within said housing, a magnetic coil defined by a wire wound about said ferrite rod to form a plurality of coils, the antenna means receiving a preprogrammed ID number from said scanned transponder; input means for generating a user selected in house ID number; mapping means for generating an in house ID number in response to said input means and for mapping said preprogrammed ID number to said in house ID number to form a mapped pair; display means for receiving said in house generated ID number and displaying said in house ID number; and processing means for processing said in house ID number when data representative of said preprogrammed ID number is received.
Claim 3
Dependent Claim
31 words
The scanner of claim 1, further comprising memory means for storing a map table corresponding to the mapping of said in house generated ID number and the corresponding preprogrammed ID number.
Claim 4
Dependent Claim
29 words
The scanner of claim 2, further comprising a housing wherein said mapping means and memory means are mounted within said housing, said memory means being removable from said housing.
Claim 5
Dependent Claim
13 words
The scanner of claim 3, wherein said memory means includes an RAM card.
Claim 6
Independent Claim
100 words
An apparatus for scanning a passive transponder comprising antenna means for transmitting a signal and receiving a signal from said transponder corresponding to a preprogrammed ID number of said transponder; input means for generating a user selected in house ID number; mapping means for mapping said preprogrammed ID number to said in house generated ID number in response to said input means; display means for receiving said in house generated ID number and displaying said in house generated ID number; and memory means for storing said in house generated ID number and corresponding transponder ID number as a mapped pair.
Claim 7
Independent Claim
100 words
An apparatus for scanning a passive transponder comprising antenna means for transmitting a signal and receiving a signal from said transponder corresponding to a preprogrammed ID number of said transponder; input means for generating a user selected in house ID number; mapping means for mapping said preprogrammed ID number to said in house generated ID number in response to said input means; display means for receiving said in house generated ID number and displaying said in house generated ID number; and memory means for storing said in house generated ID number and corresponding transponder ID number as a mapped pair.
Claim 8
Dependent Claim
17 words
The apparatus for scanning of claim 5, wherein said memory means may be removed from said apparatus.
