A method includes printing a first magnetic material onto a substrate. The first magnetic material has a first magnetic characteristic and encodes first information based on the first magnetic characteristic. The method further includes printing a second magnetic material onto the substrate. The second magnetic material encodes second information and has a second magnetic characteristic different from the first magnetic characteristic. The second information is encoded based on the second magnetic characteristic.

A wireless, proximity-based security system for securing or tracking a valuable object. The system includes a base station and a plurality of security fobs. The security fobs are tracked via an ultra-wideband transceiver relative to an outer perimeter. An administrator fob pairs each of the security fobs with the base station. An audible alarm emits from base and/or the fobs when the location of the security fob is detected to be beyond the outer perimeter. A haptic alarm emits from fob when the location of the security fob is detected to be beyond a sub-perimeter.

Embodiments of the present disclosure provide a crack sensing tag including a dielectric substrate, a tag chip, an antenna and a metal patch. The tag chip and the antenna are respectively attached to an upper surface of the dielectric substrate, the tag chip is connected with the antenna, the metal patch is attached to a lower surface of the dielectric substrate, and the antenna is connected with the metal patch. The crack sensing tag may be removed without breaking its geometry after a monitoring cycle for the next surface crack monitoring, as the occurrence of cracks is monitored. The monitoring region is a coverage region of the crack sensing tag, which is complementary to a coupling tag, enabling the further enlarging of the crack sensing region to monitor the metal member to be tested in all dimensions. The crack sensing tag identifies crack depth variations up to millimeter accuracy.

A tracking system for durable assets such as personal weapons is provided. The tracking system includes a durable asset tag including an RFID transponder physically mounted within an externally exposed cavity of the durable asset, and an identification card with a machine-readable third unique identifier associated with a person. Different embodiments are disclosed for the durable asset tag, with one embodiment including a helical antenna connected to the RFID transponder for facilitating communication with an RFID reader. The system also includes first and second databases, each storing information associated with the durable asset, and an AIM interface terminal for receiving the first unique identifier from the durable asset tag and the third unique identifier from the identification card, and which communicates with the databases for checking-in or checking-out the durable asset to the person having the identification card. The durable asset tag may be original to the durable asset or retrofitted thereto after manufacture. Methods are also provided for associating unique identifiers with a durable asset, tagging the durable asset, checking-in and checking-out the durable asset.

Disclosed is a system for detecting information of assets stored in communication tags and communicating assets information over a communication network. The system includes a bi-directional communication reader and a server. The bi-directional communication reader has at least one antenna with associated signal strength and antenna number. The bi-directional communication reader processes the received assets information from the communication tags. The server includes a database for storing asset information and further the server communicates with the bi-directional communication reader. The server stores asset information using a software application. The software application includes a front end application module for configuration, an event module, a back end application module and a communication module. The front end application module configured to receive at least one operational mode from a user. The operational mode relates to setting of operation of the bi-directional communication reader. The event module reads the asset information from the database and alerts the user if a certain event occurs. The event module sets a specific rule that triggers an event. Further the back end application module configures the bi-directional communication reader as per the selected operational mode to process the required information from the communication tags read by the bi-directional communication reader. The communication module receives processed assets information from the communication tags via the bi-directional communication reader from the specific antenna. Further, the communication module communicates the processed assets information over the communication network via a proprietary protocol.

A method includes transmitting a first magnetic detection signal at a first magnetic frequency and transmitting a second magnetic detection signal at a second magnetic frequency. The method also includes detecting a first response from a first magnetic material to the first magnetic detection signal and detecting a second response from the second magnetic material to the second magnetic detection signal. Each of the first magnetic material and the second magnetic material is associated with a substrate of the coded tag. The method further includes determining that the coded tag encodes first information based on detecting the first response and determining that the coded tag encodes second information based on detecting the second response.

A coded tag includes a substrate. The coded tag includes a first magnetic material associated with the substrate. The first magnetic material has a first magnetic characteristic and encodes first information. The coded tag includes a second magnetic material associated with the substrate. The second magnetic material encodes second information and has a second magnetic characteristic that is different from the first magnetic characteristic.
