Disclosed herein are a communication system, a monitoring system for in-situ monitoring of a substance used in a gas scrubbing process, and related methods. The monitoring system can be used to monitor the at least one substance and provide treatment data for treating the at least one substance. The communication system includes a cloud server, a first server, a second server, and a third server. The first and second servers respectively include first and second communication interfaces configured to provide spectral information to the cloud server. The cloud server is configured to generate a calibration model including at least one parameter; apply the calibration model to the spectral information provided by the second server, whereby at least one value for the at least one parameter is extracted; and provide the at least one value for the at least one parameter to the first server via the first communication interface.

Spectral data associated with a current operation of a current process performed with respect to a current substrate at a manufacturing system is received during the current process. Spectral data associated with a prior operation of the current process is identified. A difference between the spectral data associated with the current operation and the spectral data associated with the prior operation is determined. A metrology measurement value associated with the current substrate is updated based on the determined difference between the spectral data associated with the current operation and the spectral data associated with the prior operation of.

One or more embodiments relate to a sensor configuration system comprising at least one device configured to sense a first parameter; at least one device configured to sense a second parameter, and at least one interrogator device. The at least one device configured to sense the second parameter interfaces with the at least one device configured to sense the first parameter, and the at least one interrogator device interfaces both the at least one device configured to sense the first parameter and the at least one device configured to sense the second parameter where the at least one interrogator device spatially interrogates both the at least one device configured to sense the first parameter and the at least one device configured to sense the second parameter.

Fiber-optic equipment is often deployed in various locations, and performance of fiber-optic transmissions may be monitored as a gauge of equipment status to prevent costly and inconvenient communication outages. Events that damage equipment that eventually result in outage and may be desirable to address proactively, but the occurrence of such events may be difficult to detect only through equipment performance. Presented herein are techniques for monitoring and maintaining fiber-optic equipment performance via enclosure sensors that measure physical properties within a fiber-optic equipment enclosure, such as temperature, pressure, light, motion, vibration, and moisture, which are often diagnostic and predictive of causes of eventual communication outages, such as temperature-induced cable loss (TICL), incomplete flash-testing during installation, exposure to hazardous environmental conditions, and tampering. An enclosure sensor package transmits the physical measurements to a monitoring station, and automatic determination of enclosure-related events may enable triaging and transmission of repair alerts to maintenance personnel.
