Abstract: A surface temperature measuring apparatus includes a radiation thermometer (11) that measures a surface temperature (Tm) of a measurement range larger than a measurement target region of a measurement target (100), the radiation thermometer (11) detecting, by a sensor, an infrared ray radiated from an object surface of a specified measurement range to measure a surface temperature of an object, a second temperature measuring means (11) that measures a surface temperature (Tn) of a region outside the measurement target region of the measurement target (100) but within the measurement range of the surface temperature (Tm) by the radiation thermometer (11), or a region having an identical or substantially identical temperature to a temperature of the region outside the measurement target region, and a correcting means (12) that corrects the surface temperature (Tm) that is measured using the surface temperature (Tn) that is measured into a surface temperature (T) of the measurement target (100).

Abstract: One variation of a method for detecting a fire includes: during a first time period: detecting an increase in ambient light intensity and detecting an increase in ambient humidity; responsive to the increase in ambient light intensity and the increase in ambient humidity, detecting a fire event; during a second time period: correlating a decrease in ambient light intensity with an increase in visual obscuration; detecting an increase in ambient air temperature; in response to a magnitude of the increase in visual obscuration remaining below a high obscuration threshold and a magnitude of the increase in ambient temperature remaining below a high temperature threshold, classifying the fire as an incipient fire; and, in response to the magnitude of the increase in visual obscuration exceeding the high obscuration threshold and the magnitude of the increase in ambient temperature exceeding the high temperature threshold, classifying the fire as a developed fire.

Abstract: A stove guard having a data processing unit and a heat sensor arrangement for receiving heat radiation from objects located in a given field of view and for delivering the detector signals indicative of the received heat radiation to the data processing unit. The heat sensor arrangement is arranged to generate detector signals differently corresponding to the heat radiation received from a central area of the field of view than to the heat radiation received from a circumferential area of the field of view.

Abstract: Apparatuses, methods, and systems are disclosed to characterize the wear and measure temperature of a surface of a lining of a metallurgical container. Wear characterization is accomplished by a scanning device by making thickness measurements of the lining and surface temperature measurements are made using a two-color pyrometer integrated with the scanning device where surface temperature is measured by correlating a ratio of two light intensities to the surface temperature. A controller controls operation of the scanning device and the two-color pyrometer.

Abstract: This relates to sensor systems, detectors, imagers, and readout integrated circuits (ROICs) configured to selectively detect one or more frequencies or polarizations of light, capable of operating with a wide dynamic range, or any combination thereof. In some examples, the detector can include one or more light absorbers; the patterns and/or properties of a light absorber can be configured based on the desired measurement wavelength range and/or polarization direction. In some examples, the detector can comprise a plurality of at least partially overlapping light absorbers for enhanced dynamic range detection. In some examples, the detector can be capable of electrostatic tuning for one or more flux levels by varying the response time or sensitivity to account for various flux levels. In some examples, the ROIC can be capable of dynamically adjusting at least one of the frame rate integrating capacitance, and power of the illumination source.

Abstract: A method of measuring ocular surface temperature includes steps as follows. Using a built-in temperature sensor called a black plate herein, an infrared heat sensor is provided and the temperature sensor contacts the black plate. The temperature sensor measures an actual black plate temperature. The infrared heat sensor detects a radiation emitted by the black plate, and the radiation is computed according to a temperature rising curve through a computing unit of a work station to generate a computed black plate temperature. A value of temperature shifting error is determined by subtracting the actual black plate temperature from the computed black plate temperature.
