A method of operating a reactor system to provide wafer temperature gradient control is provided. The method includes operating a center temperature sensor, a middle temperature sensor, and an edge temperature sensor to sense a temperature of a center zone of a wafer on a susceptor in reaction chamber of the reactor system, to sense a temperature of a middle zone of the wafer, and to sense a temperature of an edge zone of the wafer. The temperatures of the center, middle, and edge zones of the wafer are processed with a controller to generate control signals based on a predefined temperature gradient for the wafer. First, second, and third sets of heater lamps are operated based on the temperature of the center, middle, and edge zones to heat the center, the middle, and the edge zone of the wafer. Reactor systems are also described.

Described herein are embodiments of systems and methods that utilize temperature measurements taken with head-mounted sensors as well as images of a user's face to detect fever and/or intoxication. One embodiment of a system to detect fever includes a first head-mounted temperature sensor that measures skin temperature (T.sub.skin) at a first region on a user's head, a second head-mounted temperature sensor that measures a temperature of the environment (T.sub.env), and a computer. The computer receives images of a second region on the user's face, captured by a camera sensitive to wavelengths below 1050 nanometer, and calculates, based on the images, values indicative of hemoglobin concentrations at three or more regions on the user's face. The computer can then detect whether the user has a fever based on T.sub.skin, T.sub.env and the values.

Provided is an image display apparatus including: a display section configured to display a thermal image in which temperature distribution on a subject is represented by colors, the subject including a pipe or the like for a fluid to flow therein; and a control section configured to control the display section, the control section being configured to control the display section to display the thermal image such that the temperature distribution on the subject is represented by colors within a temperature range having upper and lower limits that are settable.

A solar module detection system is provided. The solar module detection system includes a visible light image capturing device, a thermal image capturing device, a carrier, and a host. The visible light image capturing device captures a visible light image of a solar module along a moving path.

Described herein are embodiments of systems and methods that utilize images of a user's face to detect alcohol intoxication. One embodiment of a system to detect alcohol intoxication includes first and second inward-facing head-mounted cameras that are located less than 5 cm from a user's face, are sensitive to wavelengths below 1050 nanometer, and are configured to capture images of respective first and second regions on the user's face. The system also includes a computer that calculates, based on baseline images captured with the cameras while the user was not intoxicated, a baseline pattern of hemoglobin concentrations at regions on the face. The computer also calculates, based on a current set of images captured with the cameras, a current pattern of hemoglobin concentrations at the regions, and detects whether the user is intoxicated based on a deviation of the current pattern from the baseline pattern.

A scale composition determination device (10) determines that Fe.sub.2O.sub.3 has been generated in the outermost layer of a scale (SC) in the case where the absolute value of a difference between temperatures of a steel material SM measured by radiation thermometers (20a, 20b) is equal to or more than a predetermined temperature, and determines that Fe.sub.2O.sub.3 has not been generated in the outermost layer of the scale (SC) in the case where the absolute value of the difference between the temperatures of the steel material SM measured by the radiation thermometers (20a, 20b) is not equal to or more than the predetermined temperature.

Systems and methods for detecting an occurrence of a transient ischemic attack (TIA). In one embodiment, a device is utilized to measure first and second signals indicative of photoplethysmogram signals at first and second regions on the left and right sides of a user's head (PPG.sub.SL and PPG.sub.SR, respectively). A computer detects the occurrence of a TIA based on PPG.sub.SL and PPG.sub.SR that exhibit a pattern that involves the following: (i) an asymmetry between PPG.sub.SL and PPG.sub.SR, which is below a threshold, during a first period spanning more than a day; (ii) an asymmetry between PPG.sub.SL and PPG.sub.SR, which exceeds the threshold, during a second period following the first period and spanning between 5 and 180 minutes; and (iii) an asymmetry between PPG.sub.SL and PPG.sub.SR, which falls below the threshold, during a third period following the second period.
