A dynamic monitoring system with radio-frequency identification includes a radio-frequency identification (RFID) tag, at least two radio-frequency identification (RFID) detectors and a processing device. The RFID tag is installed on a moving user. When the user enters a preset detection range, at least two RFID detectors detect the RFID tag and generate an identification signal, respectively. The processing device is coupled to at least two RFID detectors. The processing device generates a distance signal between the RFID tag and the at least two RFID detectors according to the identification signals and positions of the at least two RFID detectors. The processing device generates a positioning signal relevant to a position of the RFID tag within the preset detection range according to the distance signal.

Technologies are shown for securing private information during shipping of an item storing shipping information at a blockchain address that includes a recipient geolocation address and generating a shipping label that includes a machine-readable pointer to the blockchain address. The label can be scanned to obtain the blockchain address and request the shipping information. In response to a request, the recipient geolocation address or a next intermediate shipper can be provided. The recipient can be notified to obtain authorization to release the recipient geolocation address or provide an alternative geolocation for delivery.

Systems and methods for operating a tag system. The methods comprising: emitting a wireless signal from an antenna of the tag with a first signal characteristic when the tag is proximate to an active antenna modulation marker; changing an impedance of a sensor from a first impedance value to a second impedance value when the active antenna modulation marker is exposed to a stimulus; and emitting a wireless signal from the antenna of the tag with a second signal characteristic when the tag is proximate to the active antenna modulation marker and the sensor has the second impedance value.

An impact indicator includes a micro-sensor having a mass element configured to move from a first position to a second position in response to receipt by the mass element of an impact event. The micro-sensor includes detection circuitry configured to change from a first state to a second state in response to movement of the mass element from the first position to the second position. The detection circuitry is prevented from returning to the first state in response to changing to the second state. A radio-frequency identification (RFID) module is coupled to the detection circuitry and is configured to output a value indicating that the mass element is in the second position. An activator element is configured to maintain the mass element in the first position until removal of the activator element from the micro-sensor.

Systems and methods are described for securely monitoring a shipping container for an environmental anomaly using elements of a wireless node network of sensor-based ID nodes disposed within the container and a command node associated with the container. The method has the command node identifying which of the ID nodes are confirmed as trusted sensors based upon a security credential specific to each of the ID nodes; monitoring only the confirmed ID nodes for sensor data broadcast those ID nodes; detecting the anomaly based upon the sensor data from at least one of the confirmed ID nodes; automatically generating an alert notification related to the detected environmental anomaly for the shipping container; and transmitting the alert notification to the external transceiver to initiate a mediation response related to the detected environmental anomaly.

The present invention relates to A method to detect a specific chemical substance in an environment, the method comprising:—providing a sensing layer adapted to sense the specific chemical substance;—providing a substrate layer, the substrate layer comprising a single-use wireless transmitter;—attaching the sensing layer to the substrate layer so as to form a sensing module;—detecting the amount of the specific chemical substance in the environment by means of the sensing layer;—if the amount of the specific chemical substance is above or below a first threshold, sending data representative of the sensed specific chemical substance to a receiving device using the wireless transmitter. The invention also relates to a sensing module and a kit to measure the specific chemical substance.

A method and system for cold chain monitoring of perishable goods includes at least one environmental sensor (102) to monitor at least one environmental parameter, a controller (104) to log a plurality of readings from each of the at least one environmental sensors (102), and a machine readable display (114) to display at least one alarm status associated with the plurality of readings via a barcode.

An electronic device including a continuity sensor and electrical circuitry configured to detect and report the continuity state of an article, container or product packaging is disclosed. The continuity sensor includes a first substrate with first and second coils thereon, and a second substrate with a third coil thereon. The first coil has an integrated circuit electrically connected thereto. The first substrate is part of, or is attached or secured to a part of the article, container or packaging. The second substrate is another part of, or is attached or secured to another part of the article, container or packaging. One of the article, container or packaging parts is (re)movable with respect to the other part. The first and second coils have one coupling when the article, container or packaging is closed or sealed, and a different coupling when the article, container or packaging is open or unsealed.

A wireless sensor platform design and a single walled carbon nanotube/ionic liquid-based chemidosimeter system can incorporated into a highly sensitive and selective chemical hazard badge that can dosimetrically detect an analyte down to a sub parts-per-million concentration.

A flexible sensor label including a reservoir chamber configured to store an activation medium, a plurality of first chambers, and a plurality of second chambers. Each first chamber has an associated first temperature and stores an irreversible thermochromic polymer that is altered and irreversibly changes color in response to the activation medium being released and coming into contact with the irreversible thermochromic polymer in the first chamber and an environmental temperature of the flexible sensor label corresponding to the associated first temperature of the first chamber. Each second chamber has an associated second temperature and stores a reversible thermochromic polymer that is altered and reversibly changes color in response to the activation medium being released and coming into contact with the reversible thermochromic polymer in the second chamber and the environmental temperature of the flexible sensor label corresponding to the associated second temperature of the second chamber.
