Abstract
Abstract This invention relates to LIMIS systems, devices and methods. Specifically, it relates to the attachment of passive transceivers which can be altered or coded, erased and recoded to various items as "tags", and the use of active transceivers of various types for Location, Identification, measurement of the Movement of, Inventory and analytical, control, guidance and sorting Systems (LIMIS) using and analyzing the information received from the items. The devices include at least one small unitary, passive transceiver (PT) and at least one active transceiver (AT) and where necessary, one or more repeater-relays and/or reflectors. The PT is attached to or embedded in the item to be identified. The PTs are encoded, decoded, identified, and located and/or their motion is detected and/or measured by the AT. The AT unit functions can be accomplished by one or more independent devices or a single device.
