摘要： Method, apparatus, and computer program product are provided for determining a maximum temperature to which a perishable good or other temperature sensitive item was exposed. In some embodiments, a capacitance of a circuit provided on a substrate is measured. The circuit includes capacitor(s) each having first and second plates separated from each other by an ionic liquid (IL) in a solid state. The IL melts at a predetermined temperature and flows away from the first and second plates into a void. In some embodiments, the predetermined temperature at which the IL melts is different for each capacitor. For example, each capacitor in the circuit may employ a different N-alkyl bezothiazolium salt. A maximum temperature of exposure is determined based on the measured capacitance. In some embodiments, a decision of whether to discard the perishable good or other temperature sensitive item may be based on the determined maximum temperature.

摘要： A recording control apparatus configured to access a plurality of recording media, includes a control unit configured to set a temperature threshold of each of first and second recording media, a functional restriction being imposed on the recording medium at the temperature threshold, wherein the control unit is configured to, in recording data read from the first recording medium into the second recording medium, make a first setting for the first recording medium and a second setting for the second recording medium, where the first setting includes setting the temperature threshold of the recording medium at which the functional restriction is imposed on the recording medium to a default value of the recording medium, and the second setting includes setting the temperature threshold of the recording medium at which the functional restriction is imposed on the recording medium to a value greater than the default value of the recording medium.

摘要： The invention relates to a device (6) for communicating data with a data logger (28) that measures the temperature of ambient gas and logs the temperature data into a memory (55). The device (6) includes a body (73) for mounting a data logger (28) thereon, wherein the data logger (28) is disposed inside a capsule (12, 40). The data logger (28) includes: top and bottom covers (50, 51) that define an enclosed space and includes an electrical circuit (52) disposed in the enclosed space and having a memory (55) for storing data; a pair of electrodes (71, 72) for extending through two holes (18, 32) formed in the capsule (12, 40) and contacting the top and bottom covers (50, 51) of the data logger, respectively; a processor (1001) for retrieving data stored in the memory (55) through the pair of electrodes (71, 72); and a communication device (1015) for transmitting the data.

摘要： A method and apparatus may include activating, by a network node, power of a global-positioning-system receiver or power of an active antenna of the global-positioning-system receiver. The apparatus uses the global-positioning-system receiver to perform synchronization of the apparatus. The method may include receiving at least one measurement, wherein the at least one measurement includes real-time, predictive, or historic data. The method may also include determining a holdover duration based on the at least one measurement. The holdover duration corresponds to a length of time where the power of the global-positioning-system receiver or the power of the active antenna is to be turned off. The method may also include deactivating the power of the global-positioning-system receiver or the power of the active antenna for the holdover duration.

摘要： Systems and methods for temperature monitoring and environmentally related calculations are disclosed herein. A system according to embodiments herein may include a memory, a network interface, and one or more processors. The system may receive one or more environmental readings from a sensor taking readings at an environmentally controlled area. The system may further determine a timestamp corresponding to each of the one or more readings and calculate, using the one or more readings and their corresponding timestamps, an exposure of a good stored within the temperature controlled area. The system may further determine that the calculated exposure of the good has surpassed a pre-determined exposure threshold for the good and send an electronic message configured to indicate such determination to a user. The system may use a neural network to predict future readings based on current readings and use the predicted future readings in methods described herein.

摘要： Systems and methods of the present invention allow to determine ambient gas temperature in harsh environments such as in a steam autoclave chamber during a sterilization process. In certain embodiments of the invention, temperature data is gathered using a sensor that is placed in an enclosed electronics-based temperature logging device. A capsule seals the temperature logging device except for a through hole that, during regular operation, allows gas to directly contact a surface of the temperature logging device in order to reduce a time lag between the data logging device and an ambient gas. As a result, the data logging device accurately can track temperature variations when placed, for example, inside a chamber.

摘要： A method, a system, an electronic device, and a storage medium for storing and collecting temperature data are disclosed. The storage method includes: acquiring starting time data corresponding to a temperature recording time period and acquiring actual temperature data corresponding to each time stamp; obtaining at least one piece of target compressed data corresponding to the temperature recording time period by compressing the actual temperature data; and storing the starting time data and the target compressed data corresponding to the temperature recording time period into a storage space of a temperature recorder. In the present disclosure, multiple pieces of temperature data may correspond to one piece of compressed data (for example, 1 bit), so that each piece of temperature data only occupies a small storage space, and starting time data and multiple pieces of compressed data are stored in a temperature recorder together, thereby effectively improving the storage performance of the temperature recorder, and achieving rapid collection of the temperature data. The blockchain-based verification for the collected temperature data ensures the security and authenticity of temperature data collection and prevents data from being tampered with.

摘要： A sensor assembly with a sensing element sends a sensor signal from the sensing element to attached process transmitter over sensor connection wires. The sensor assembly has memory circuitry for storing information related to the sensor assembly and interface circuitry that provides for digital communication of the stored information with the attached process transmitter. This digital communication is sent over the sensor connection wires.
