Abstract
A mobile sensor system and method for managing inventory of a store includes at least one radio frequency identification (RFID) scanner for receiving readings from RFID tags, at least one external sensors for detecting at least one external events other than RF signals from the RFID tags, and a processor configured to update an RFID database for storing the readings from the RFID tags, wherein the update is based on a correlation function of the readings from the RFID tags and the external events detected at the at least one external sensors.
Claims21
A mobile sensor system for managing inventory of a store, comprising:
- at least one radio frequency identification (RFID) scanner for receiving readings from RFID tags;
- at least one external sensor for detecting at least one external event other than RF signals from the RFID tags;
- and
- a processor configured to update an RFID database for storing the readings from the RFID tags, wherein the update is based on a correlation function of the readings from the RFID tags and the at least one external events detected at the at least one external sensor.
A mobile sensor system for managing merchandise inventory of a store, comprising:
- at least one radio frequency identification (RFID) scanner for receiving readings from RFID tags;
- and
- at least one external sensor for detecting at least one external event other than RF signals from the RFID tags;
- wherein the at least one RFID scanner is triggered on or off as a function of the at least one external event detected at the at least one external sensor.
A method of using at least one RFID scanner and at least one external sensor other than the at least one RFID scanner for managing inventory of a store, comprising:
- receiving readings from RFID tags;
- detecting at least one external event;
- and
- updating an RFID database for storing the readings from the RFID tags, wherein the update is based on a correlation function of the readings from the RFID tags and the at least one external event detected at the at least one external sensor.
