    摘要： 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.

    摘要： A method and system for tracking an asset in an indoor facility. The method includes receiving, from a first mobile device, an asset tracking tag collision report, the asset tracking tag collision report including a tag identifier of an asset tracking tag associated with an asset; determining a new location of the asset based on the received asset tracking tag collision report; updating an asset location database to indicate the new location of the asset; and, in response to determining the new location of the asset, transmitting an instruction message to a mobile device to cause the mobile device to direct the asset tracking tag to cease broadcasting the wireless signal. The method and system use crowd-sourcing to determine a new location of an asset that has moved in an indoor facility.

    摘要： Methods and systems of processing transponder signals received from transponders to identify the transponders are provided. A first signal including a first code and a first identifier may be received from a first transponder. The first identifier is written to the first transponder by an RFID writer when the first transponder is placed proximate to the RFID writer, and the first identifier is used to associate transponders with a first user. A second signal including a second code and the first identifier may be received from a second transponder. The first identifier is also written to the second transponder by the RFID writer when the second transponder is placed proximate to the RFID writer. The first and second transponders are associated with the first user based on receiving the first identifier from both the first and second transponders.
