摘要:
An electronic indicator includes a circuit having an environmentally sensitive component having a sensing component treated with or containing a material so as to be sensitive to an environmental condition. The material can be a colloidal polymer that is reactive with an environment to cause a change in a characteristic of the environmentally sensitive component. The circuit is configured to detect the change and to communicate the change.

An electronic assembly may be contained in a label that performs time-temperature integration (TTI) and indicates that time and/or temperature levels have been reached that may compromise the quality, shelf life, or safety of the item to which the label is affixed. The label may be used on a wide variety of objects that require careful handling in terms of temperature and/or time elapsed before use. The labeling system includes circuitry that measures and calculates, and indictor(s) that signal that the time has come for discounted sale, and, later, that the time has come for disposal rather than sale. Optionally, the circuitry may act as an “over-temperature alarm” system, to measure, calculate, and indicate when a one-time temperature violation has occurred that is of such a magnitude that the item is immediately considered compromised or spoiled.

One apparatus embodiment includes an electronic assembly, equipped to sense one or more changes in an environmental condition. The assembly includes a logic circuit coupled to: one or more environmental sensors, memory that provides data storage, and a wireless communicator. The logic circuit is configured to perform time measurement, perform environmental measurement with the one or more environmental sensors, store time-stamped environmental data in the memory, and communicate with particular other electronic assemblies, equipped to sense one or more changes in an environmental condition, via the wireless communicator. The logic circuit is also coupled to a power source that provides power to at least one of the logic circuit and the wireless communicator.

A system and method are disclosed for monitoring environmental conditions of a perishable product. The system includes an environmental sensor configured to sense one or more environmental conditions of the perishable product and an analog integrator in communication with the environmental sensor, the analog integrator being formed on a polymer substrate and including one or more tunable components. The system also includes a comparator in communication with the analog integrator and configured to change state when an output of the analog integrator reaches a selected threshold level, and a control module in communication with the comparator and the analog integrator. The control module is configured to control the operation of the analog integrator based on an output of the comparator.

Methods, mediums, systems, and devices for redundant monitoring are disclosed. One method of providing redundancy in an environmental monitoring device includes combining a first sensor, one or more redundant sensors, and a plurality of control logic components; monitoring a selected environmental condition using the plurality of sensors; measuring the selected environmental condition using the plurality of sensors each reporting to a particular control logic component among the plurality of control logic components, each of the plurality of control logic components monitoring a sequence of such measurements; and correlating corresponding monitored measurements from the sequence of measurements of each of the plurality of control logic components and determining whether a difference exists between the corresponding monitored measurements of each of the plurality of control logic components.

One apparatus embodiment includes an electronics assembly including an environmental sensor, memory that provides data storage, a logic circuit, an indicator component, and a power source for providing power to at least one of the logic circuit and the memory. The logic circuit can be designed to perform a time measurement, perform an environmental measurement with the environmental sensor, and/or initiate an alarm status when a calculated alarm event time occurs based upon the environmental measurement. The indicator component can be connected to the logic circuit for displaying the alarm status.
摘要:
An environment monitoring method including measuring data from a plurality of sensors, wherein each of the plurality of sensors includes a unique identifier (UID). The method further includes instructing each of the plurality of sensors to measure data. The method also includes receiving the measured data from each of the plurality of sensors. The method then calculates a product degradation value of a product based on the measured data and compares the product degradation value with a threshold product degradation value. In response to the product degradation value of the product exceeding the threshold produce degradation value, the method generates and sends an alert to a device.
