A sensor device for detecting transport parameters representative of those experienced by a sample during transportation is provided. The sample is stored in a container. The sensor device includes a housing with a configuration that generally matches the configuration of the container, a hardened substrate portion formed from a substrate material, and a sensor assembly comprising at least one sensor for detecting at least one transport parameter (e.g. acceleration, orientation, temperature, etc.). The sensor assembly is secured within the housing by the hardened substrate portion. Optionally, a weight of the device approximates a combined weight of the container and the sample stored therein. The weight of the sensor device can be adjusted. When the device is positioned proximate to the container during transportation, the at least one transport parameter detected by the at least one sensor is analogous to that at least one transport parameter experienced in the container.

A data collection device includes a housing and a data collection unit located in the housing. A power unit is located in the housing and is operably connected to the data unit to provide power for operation of the data unit. An irradiation sensor is located at the data collection device to detect exposure of the data collection device to irradiation. An irradiation sensor includes a thermal energy absorbing material and a thermal energy sensitive material in thermal communication with the thermal energy absorbing material. The thermal energy sensitive material is characterized by a change in color when exposed to a selected degree of thermal energy due to irradiation.

A data logger for logging values of a physical environment parameter as a function of time includes a sampling subsystem which acquires a sequence of sample values of the physical environment parameter at sampling moments which are separated by sample intervals, an encoding subsystem which converts the sequence of sample values in data records including a representative value representing groups of one sample value or a number of successive sample values with variations which meet a stability criterion and information representative of the lengths of the groups, a memory subsystem which stores a sequence of defined data, and the data logger is arranged to determine in which range of a plurality of ranges a sample of the environment parameter is located, and to use a stability criterion for the encoding which depends on the determined range.

A delivery unit 15 is mounted on a vehicle 21 and is used to deliver the articles accommodated in a storage container 33 filled with a cooling gas. The delivery unit 15 includes a thermometer Se1 that measures a temperature in the storage container 33, a memory unit 53 that memorizes therein data of the measured temperature in chronological order, a quality-data generation unit 55a that generates quality data of articles based on temperature data acquired from the memory unit 53, a print-data editing unit 55h that edits print data relating to a quality certificate including a graphic image representing the quality in chronological order of the cooling environment in the storage container 33 accommodating articles therein during delivery based on a serial number of the article and the quality data, and a printer 27 that prints print data relating to the quality certificate on a recording medium.

A temperature indicator includes a compound comprising an ionic fluid disposed in contact with an absorbent medium at a first location. Detection circuitry is coupled to the absorbent medium at a second location spaced apart from the first location. Communications circuitry is coupled to the detection circuitry and is configured to output a value indicating an actuation state of the temperature indicator indicated by the detection circuitry. Responsive to the temperature indicator being exposed to a temperature exceeding a temperature threshold, the compound migrates along the absorbent medium from the first location toward the second location. The detection circuitry is configured to indicate the actuation state based on a presence of the compound at the second location.
