In one aspect where a load or a subset of one or more tags is in motion relative to an RFID reader system, the RFID system obtains tag readings and derives tag scalar or vector motional data e.g. tag velocity, tag acceleration, and/or rate of change of tag acceleration which can be compared to known tag motional information to distinguish true tags of interest from false positives which are unavoidably also within the field of the reader system. An antenna system may also make readings during distinctive movement patterns of true tags, such as vertical or arcuate movement and utilize computed tag motional data based on the tag readings to distinguish true tags from false positives. Two components of the RFID system may communicate information on identified tags, and/or interact (e.g. by silencing tags), so as to cooperate in identifying true positive tags.

Utilization of motion and spatial identification in RFID systems

An RFID system is used to detect whether an RFID tag is part of the load of a forklift or other transport device. In one aspect where the load is in motion relative to an RFID reader system, the RFID system obtains tag readings and derives tag vector motion information which can be compared to the known motion of the load to distinguish tags that are part of the load from false positives which are unavoidably also within the field of the reader system. A forklift antenna system may also make readings from load pickup to load deposit in a truck trailer, and utilize computed tag vector motion information to distinguish tags that are part of the load from false positives. The tag vector information my relate to tag velocity, tag acceleration, and/or rate of change of tag acceleration. The two components of the RFID system may communicate information on identified tags, and/or interact (e.g. by silencing tags), so as to cooperate in identifying true positive tags in the load. A portal or reader system location along the path of the forklift can be activated prior to arrival of the load to eliminate certain false positives from requiring evaluation while the forklift load is moving through the field region of such reader system. Vertical motion of the load can be utilized as a way of discriminating between true positive tags in the load and false positives.

Utilization of motion and spatial identification in mobile RFID interrogator

A mobile system having a portable fingerprint collecting system for generating a digitized image of a fingerprint collected from a subject, a database system configured to store a database containing a plurality of fingerprint templates cross-referenced with identification information, the database system configured to compare the digitized fingerprint images generated by the portable fingerprint collecting device with the fingerprint templates stored in the database to provide identification information for the fingerprint, and a communication system providing real time communication of the digitized fingerprint image and identification information between the portable fingerprint collecting system and the database system.
