A thickness measurement method includes: heating a surface of the measurement object in a dot shape by a heating device; generating a thermal image corresponding to a temperature of the surface of the measurement object by capturing an image of the heated surface of the measurement object at a predetermined time interval by an imaging device; acquiring temperature data indicating temporal changes in temperature at multiple positions on the surface of the measurement object based on the thermal image generated by the imaging device; fitting a solution function indicating a solution of a heat conduction equation corresponding to a point heat source and including a parameter related to the thickness of the measurement object to the temperature data; and calculating the thickness of the measurement object based on a value of the parameter in the fitted solution function.

This disclosure relates generally to accretion detection, and more particularly to system and a method for accretion detection within an iron kiln. The iron kiln includes a cylindrical body for holding and processing molten iron ore. In one embodiment, method includes receiving, in real-time, a first plurality of temperature values from a plurality of sensors configured on distinct locations on the outer surface of the iron kiln and is associated with a distinct sensor ID. The plurality of temperature values are compared with a reference temperature value to identify deviation in temperature gradient associated with the outer surface. Subsequently on identifying the deviation corresponding to one or more sensors, a second plurality of temperature values of surrounding locations of the one or more sensors is recorded and the presence of the accretion in the iron kiln is determined based on the second plurality of temperature values.

An optical coherence tomography system for ophthalmic use identifies tissue by selected laser heating of that tissue at reduced power levels decreasing background noise to boost signal-to-noise ratio allowing detection of minute changes in thermal expansion caused by that heating at clinically acceptable levels.

Fluid flow systems can include one or more resistance temperature detectors (RTDs) in contact with the fluid flowing through the system. One or more RTDs can be operated in a heating mode and a measurement mode. Thermal behavior of the one or more RTDs can be analyzed to characterize a level of deposit formed on the RTD(s) from the fluid flowing through the system. Characterizations of deposition on RTDs operated at different temperatures can be used to establish a temperature-dependent deposition profile. The deposition profile can be used to determine if depositions are likely to form at certain locations in the fluid flow system, such as at a use device. Detected deposit conditions can initiate one or more corrective actions that can be taken to prevent or minimize deposit formation before deposits negatively impact operation of the fluid flow system.

The invention relates to an inspection method of a shoe worn by a foot of an individual comprising the following steps: acquiring (S1) a thermal image of the shoe when it is worn by a foot of the individual by means of a thermal camera, determining (S2), from the thermal image of the shoe, a lower limit of the foot of the individual, determining (S3) a position of the shoe relative to the thermal camera at the time of acquisition of the thermal image, and deducing (S4) of the position of the shoe relative to the camera and of the lower limit of the foot, a distance between the lower face of the sole and the lower face of the foot of the individual.

Upon determining a mobile object is approaching an ice layer above a body of water, a thermal image of the ice layer is obtained. The thermal image and ambient temperature data are input to a neural network that outputs a plurality of regions of the ice layer and respective estimated thicknesses for the regions. A classification for each region is determined based on its estimated thickness and the mobile object. The classification is one of preferred or nonpreferred. The classifications for the regions are output.
