摘要： Systems (100) and methods (400) for determining a Handheld Reader's (“HR”) location within a facility. The methods involve: performing first operations by HR to read RFID tags having locations within the facility that are unknown to the handheld reader; performing second operations by HR to receive signals from RF Enabled Devices (“RFED”) located at known locations within the facility; and determining HR's location/orientation using RSSI levels or TOF values of signals received from RFEDs, known locations of RFEDs, sensor data, known antenna patterns of RFEDs, a known antenna pattern of HR, and/or (9) information indicating which RFID tags were read by HR and at least one RFED. The first and second operations are performed while HR is being carried by a person throughout the facility.

摘要： Systems and methods for operating a pedestal of an Electronic Article Surveillance (“EAS”) system. The methods comprise: capturing at least one first image or video by a camera coupled to the pedestal; analyzing the at least one first image or video to detect a person's presence and determine the person's location relative to the camera; determining a first beam pointing direction for the pedestal based on results of the analysis of the at least one first image or video; and steering a read beam of the pedestal in accordance with the first beam pointing direction so that a main lobe of the pedestal's antenna field pattern covers a first area of an interrogation zone.

摘要： Systems and methods for detecting a presence of a person, robot or object in a given area using a hybrid Lighting and Inventory (“LI”) system. The methods comprise: maintaining a data store of identifiers for first tags that are readable by an internal circuit of at least one light provider; tracking (a) changes in which of said first tags are read by the at least one light provider's internal circuit during consecutive tag read processes and (b) changes in power levels of tag read signals received at the at least one light provider during the consecutive tag read processes; and using tracked information (a) and (b) to detect the presence of the person, robot or object in the given area.

摘要： Systems and methods for operating a Radio Frequency Identification (“RFID”) tag. The methods comprise: monitoring a level of Radio Frequency (“RF”) energy being received by the RFID tag; performing operations by a circuit of the RFID tag to compare the level of RF energy in a given frequency band to a first threshold value; and transitioning an operational mode of the RFID tag from a first operational mode in which a receiver is disabled to a second operational mode in which the receiver is enabled, when the level of RF energy exceeds the first threshold value. The RFID tag is able to communicate with a remote tag reader when the RFID tag is in the second operational mode and not when the RFID tag is in the first operational mode.

摘要： Systems and methods for operating an RFID tag. The methods comprise: inducing current through a magnetic loop or solenoid disposed within the RFID tag that is caused by a inductive field, a magnetic field or an RF field being generated within a surrounding environment; using the current which is induced through the magnetic loop or solenoid to charge a capacitor disposed within the RFID tag; decreasing the amount of current induced through the magnetic loop or solenoid; receiving a detaching signal at the RFID tag; electrically connecting the capacitor to a detaching unit disposed within the RFID tag in response to the detaching signal; and activating the detaching unit by supplying current from the capacitor to the detaching unit, whereby the RFID tag can be detached from an article.

摘要： Systems and methods for operating a tag. The method comprising: causing motion of a spherical permanent magnet which is disposed and freely movable in a three dimensional internal space of a non-magnetic hollow sphere located within the tag; using the spherical permanent magnet's motion to cause a change in a magnetic flux in a wire wrapped around at least a portion of the non-magnetic hollow sphere, where the change in the magnetic flux induces a current in the wire; and supplying the current to at least one device of the tag's internal electronic devices that is configured to facilitate at least one of an inventory count and an inventory security.
