Abstract: Systems and method for operating and monitoring refrigerators are described. Temperature cycles within the compartment are characterized using statistical, frequency and pattern analysis techniques to derive a steady-state characteristic of temperature within the compartment. A thermal sensor inside the conditioned area is monitored and temperature data sets can be analyzed to determine performance in comparison to a baseline, and energy consumption. Analysis of continuous temperature readings taken from individual or groups of freezers identifies patterns of variations in temperature cycles from which feedback on efficiency can be inferred. Electrical load can be determined by measuring or estimating current usage and identifying periods of time when compressors are active in the refrigerator.

Abstract: A method and an apparatus are provided that may be applicable to refrigeration assets, including refrigeration plants and cold-storage facilities comprising large numbers of refrigeration assets. The performance of refrigerators and refrigeration devices may be monitored based on temperature and electrical current and other measurements known or deemed to be correlated with refrigeration performance. Refrigeration assets in need of repair may be identified and a repair process may be specified, classified, managed and optimized. The immediate effectiveness and long-term persistence of repairs may be determined over time. The refrigeration assets may be classified according to reliability, performance, make, model and manufacturer. The effectiveness of repairs may be classified based on measured performance results following repairs.

Abstract: Systems and methods are described for tracking a shipping container. Information from a third-party shipping entity is combined with information retrieved from a data logger attached to the shipping container while the shipping container is in transit. The third-party portal provides updates through Email or the like, transmitted to an address that is uniquely associated with the shipping container and its current itinerary.

Abstract: A method and an apparatus and a computer program product are provided that can monitor thermal mass or thermal energy sources available at remotely-located equipment using wired or wirelessly connected sensors. The method may include to receiving measurements captured by one or more sensors coupled to the equipment, the measurements including measurements indicating remaining quantities of thermal mass or thermal energy sources available for use by the equipment, monitoring replenishment events in which the thermal mass or thermal energy sources are resupplied, generating a thermal efficiency and usage or characteristic describing thermal efficiency and a cycle of usage of the thermal mass or thermal energy sources based on historical measurements of thermal efficiency and quantities of thermal mass or thermal energy sources consumed and stored by the equipment and a history of replenishment events, and scheduling one or more replenishment events based on the usage characteristic.

Abstract: Systems, methods and apparatus may be applicable to managing and monitoring refrigeration assets, including refrigeration plants and cold-storage facilities comprising large numbers of refrigeration assets. A method of managing refrigeration systems includes receiving measurements captured by a plurality of sensors deployed with a refrigeration asset, the measurements being related to temperatures within a temperature-controlled chamber of the refrigeration asset, identifying a difference between a first temperature measurement obtained from measurements provided by a first sensor and a second temperature measurement obtained from measurements provided by at least one sensor, and calibrating the first sensor based on the difference between the first temperature measurement and the second temperature measurement.
