Systems and methods for detecting a deposit in a vessel with a sensing cable including an optical fiber sensor array aligned with a heating element disposed in the vessel. An excitation source is configured to propagate at least one heat pulse through the heating element along at least a portion of the sensing cable to affect an exchange of thermal energy between the heating element and media exposed to the sensing cable. An optical signal interrogator is adapted to receive a signal from a plurality of sensor locations and configured to measure, a temperature profile corresponding to the heat pulse at the sensor locations. A control unit is configured to detect a deposit by determining one or more properties of the one or more media exposed to the sensing cable at each of the plurality of sensor locations based on the temperature profile corresponding thereto.

Tool bodies, tools and machines for operating the tool include electronic circuits for providing data, collecting data, analyzing data and for controlling machines based on such data.

A method for performing sub-surface porosity detection in an additively manufactured part. The method includes providing, by a laser radiation source, a first radiation to a region of a powder bed along a beam of the first radiation, the region of the powder bed being part of a corresponding region of an additively manufactured part. Infrared imaging of the region of the powder bed is performed while the first radiation is being provided to the powder bed. A processor generates data sets indicative of the temperature of the region of the powder bed; and the processor further detects, from the data sets, a defect signature indicative of the formation and/or presence of a sub-surface defect in the region of the additively manufactured part.

System and method for quantifying qualitative turf conditions as they relate to turf performance and health. In an embodiment, data is collected about turf condition using a turf analysis device. The data collected aboute the conditions may be used to generate condition-based turf stress indexes that may be used to genasrte an overall a Turf Performance Indicator (TPI). Such collections are calculated through a unique quantitative mathematical equation resulting in a measurable quotient that is used to assess overall turf performance qualities on a relative scale over time. Using an integrated Global Positioning System (GPS), the TPI measurements can be used to identify overall property conditions and zone specific conditions within that property. Such analysis is viewed with visual analysis methods using a cloud based system.
