摘要： Systems and methods for determining an inventory. The methods comprise: performing operations by an internal circuit of a light provider to control operations of a light element to produce visible light, where the light provider is coupled to a light fixture installed on a physical structure of a facility; and performing operations by the internal circuit to connect with a network, receive a tag identifier associated with an alert event from at least one external device via the network, read tags, and control the light element to modify at least one characteristic of the visible light produced thereby when information read from one of the tags includes the tag identifier.

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 determining a physical location of a first Radio Frequency Identification (“RFID”) tag. The methods involve: analyzing timestamped tag read information acquired during multiple tag reads to determine a first physical location for the first RFID tag read by the mobile reader while moving through a facility; identifying second RFID tags from a plurality of RFID tags read by the mobile reader that are located in proximity to the first RFID tag and that are coupled to objects similar to an object to which the first RFID tag is coupled; selecting an RFID tag from the second RFID tags that has a first location confidence value associated therewith which is greater than second location confidence values associated with other RFID tags of the second RFID tags; and modifying the first physical location based on a second physical location of the RFID tag selected from the second RFID tags.

摘要： Managing foreign RFID tags within a secured area involves use of a first RFID portal system to read tag data from an RFID tag present within a first portal zone. A processing device associated with the first RFID portal system is used to determine whether the RFID tag is entering the secured area. The determination is based on an evaluation of a direction of travel of the RFID tag through the first portal zone. Responsive to determining that the RFID tag is in fact entering the secured area, one or more operations are performed to cause a first tag value corresponding to the tag data to be added into a safe to exit (STE) list.

摘要： Systems and methods for finding tags which are unreadable at a particular time. The methods comprise: performing first operations by a first mobile tag reader to read tags at a first time and to determine physical locations of the tags which were read at the first time; and performing second operations by the first mobile tag reader or a second mobile tag reader at a second later time for determining a first geographic area in which a first tag which is unreadable resides. The second operations comprise: analyzing tag read data associated with the first operations to identify second tags which were read along with the first tag on a previous occasion; and selecting the first geographic area to comprise a second geographic area defined by the physical locations of the second tags which were determined during the first operations by the first mobile tag reader.
