have their complete medical records in hand. Lost or
misplaced
records are unavailable to the physicians. The cost of and
time for finding the records is expensive and potentially
life-threatening. Even when conditions are not life-
threatening, losses are incurred when extra tests are given,
diagnoses are delayed, and billing is delayed because records
cannot be found.
The invention at issue attaches transmitter tags to
records and uses receiver base stations (RBSs) in
communication with a host computer. The tags are
preprogrammed with a tag identification number used to
associate the record to be tracked with a particular tag. The
RBSs are positioned to provide a reception range overlap area
for positively tracking the records as they travel through
different reception regions. The sensitivity of each RBSs’
receiver may be adjusted to control the size of its reception
range.
