A temperature measurement device 25A is a temperature measurement device 25A that includes a temperature sensor 25d and that is accommodated in a container 21 along with an article 23, and includes a temperature deviation determination unit 25h that determines whether a temperature of the article 23 in the container 21 having been detected by the temperature sensor 25d at a predetermined measurement interval has deviated from a reference temperature range, a control unit 25g that enables a temperature deviation flag when the number of times the temperature of the article 43 in the container 21 has consecutively deviated from the reference temperature range exceeds a reference number as a result of determination by the temperature deviation determination unit 25h, and a notification unit 25f that notifies a fact that the temperature deviation flag has been enabled by the control unit 25g.

A wireless hand hygiene compliance tracking system and related techniques are disclosed. The system may include one or more micro-zone (mZone) transmitters configured to be deployed at designated locations where hand hygiene compliance is desired. A given mZone transmitter may transmit an mZone signal including data pertaining to its type and identity, from which its purpose and location may be derived. A monitored individual may host a beacon tag configured to receive the mZone signal and pull mZone type and identification data therefrom, relaying that data in its own beacon signal, along with current hand hygiene compliance or non-compliance status data. The beacon tag may be programmed with one or more hand hygiene compliance modes selectable based on the desired monitoring context. The beacon signal may be received by any gateway or reader device within transmission range. In this manner, compliant and non-compliant events may be tracked.

An RFID-based sensing method including receiving, from an RFID tag with a tuning circuit when the tuning circuit is arranged in a first state, a first RF signal; and receiving, from the RFID tag when the tuning circuit is arranged in a second state, a second RF signal. The tuning circuit is arranged to affect or facilitate impedance matching of an antenna and an integrated circuit of the RFID tag. The method also includes processing the first and second RF signals received to determine respective differences in two or more properties of the first and second RF signals received; and determining, based on the processing, a status associated with an environment in which the RFID tag is arranged.

Health of perishable commodities such as eatables deteriorate over time. State of art systems for health monitoring of perishable commodities rely on measurement of limited parameters and also fail to consider effect of environment on the health of the perishable commodities. Disclosed herein is an apparatus and method for multimodal sensing and monitoring of perishable commodities. The apparatus allows to change environment within a closed chamber in which the perishable commodity being monitored is kept, and in turn allows to generate health data in different environment settings. This data is used to generate a health model. Data collected in real-time are processed with the health model to establish a correlation with at least one image, wherein each of such images in the health model represents certain health state. Based on the established correlation, health of the perishable commodity is determined.

The invention relates to the monitoring of products by means of active radio tags. According to the invention, packagings of products are provided with an active radio tag that detects at least one environmental condition and/or at least one packaging state, and which emits a signal at time intervals, which provides information about a unique identifier and at least one state in which the respective product is found. The signal is picked up by a receiver that extracts the unique identifier and the state information and transmits together with location information to a computer system.

An agricultural work machine, an agricultural work machine control system, and method for an agricultural work machine having Bluetooth enabled RFID tags to determine a fault condition of machine components, devices, parts or systems. The Bluetooth enabled RFID tags are located on, at, or near machine components or systems to sense a temperature of those components or systems. The Bluetooth enabled RFID tags are interrogated to determine sensed temperatures and component identifiers. A controller receives the temperatures and component identifiers and compares the received temperatures to a threshold to determine whether a fault condition exists. If so, the controller transmits an alert signal to a user interface to indicate that a fault condition exists with an identified component, part, device, or system.

A tracking tag system includes a tag case, a first tag case back plate and a second tag case back plate. The tag case has a mating surface and is configured to house a PCB having a transmitter and circuitry for controlling the transmitter. The first tag case back plate is configured to mate with the tag case to enclose and totally protect the PCB, the transmitter, the circuitry and a battery of a first type against ingress of water during immersion and against dust ingress. The second tag case back plate configured to enclose and totally protect the PCB, the transmitter, the circuitry and a battery of a second type against ingress of water during immersion and against dust ingress.

Small, low-cost satellite systems, like CubeSats or other microsatellites, can exhibit reduced reliability relative to higher-cost satellite systems. This can result in difficulty identifying, communicating with, and tracking such satellite systems when they fail. Provided herein are reliable, low-cost, low-energy, turn-key systems for identification and tracking of small satellites that can be readily added to a microsatellite with minimal integration costs and while occupying a minimal amount of volume, mass, and external area of the host satellite. These systems are electrically isolated from the satellite bus, being powered by internal batteries or other separate energy sources and providing reliable identification and tracking even when the other systems of the satellite have failed. These improved identification and tracking systems include space environment sensors to maintain the system in a very-low-power state while the system is in vehicle processing and transit on Earth, extending device lifetime and reducing cost and weight.

A luggage tag comprises an indicator; a thin tag body including a radiofrequency (RF) receiver configured to receive an RF signal transmitted by an RF transmitter and a processor in communication with the RF receiver and the indicator, the processor being configured to acquire information from the RF signal that is received by the RF receiver and to turn on the indicator in response to the information acquired from the RF signal; and means for coupling the thin tag body of the luggage tag to luggage.
