    摘要: Systems and methods disclosed herein use a multi-color pyrometer configured to determine a first temperature in a high temperature range and a single-color pyrometer configured to determine second temperature in a low temperature range. The system uses information gained from determination of the first temperature in the high temperature range to facilitate later determining the second temperature in the low temperature range. The first temperature in the high temperature range and the second temperature in the low temperature range are used to monitor and control different engine operations that occur at different times.

    摘要: A system controller includes a light source, an optical guiding assembly, a sensor and a feedback controller, and is applied to perform a solder operation with a solder module. The light source emits waveband light guided to a to-be-soldered area for heating. The optical guiding assembly is disposed between the light source and the solder module, and the waveband light is guided to the solder module by the optical guiding assembly. The sensor is disposed on another side of the optical guiding assembly for receiving a sensing light beam and then generating a sensing signal. The sensing light beam is guided to the sensor by the optical guiding assembly. The feedback controller is connected with the sensor and the light source for receiving the sensing signal and then controlling the light source. The system controller is a static part, and the solder module is a dynamic part.

    摘要: One or more temperature measuring devices are described that comprise; thermal imaging cameras capable of detection and provision of an exact location of at least one created dynamic image scanned by and triangulated with at least two thermal imaging cameras, and a gate that provides a constrained targeted pathway through which at least one person must travel so that dynamic thermal data of the person is captured as the person is moving through the gate and wherein thermal imaging cameras are geometrically arranged in positions such that the thermal imaging cameras field of view exist on or within the gate and wherein the person is scanned and provides targeted dynamic thermal data that is converted into one or more temperature readings that measure and transmit the temperature readings from one or more photodetectors that sense thermal radiation naturally emitted by people passing through.

    摘要: A thermal conductivity measuring device includes a sample holder, a light source designed to emit a pulse of light of a predetermined impulse energy, an optical system for directing the pulse of light in a light path onto the sample in the sample holder, an infrared sensor for time-dependent detection of an infrared radiation intensity emitted by the sample, and an evaluation unit designed to automatically calculate the thermal conductivity of the sample on the basis of the time-dependent infrared radiation intensity. In addition, the light source has a continuous wave laser that is designed to emit an intensity-modulated laser beam, the intensity of which is modulated with an intensity modulation frequency. The light source is arranged to emit the laser beam along a light path. The evaluation unit is designed to automatically calculate the thermal conductivity of the sample on the basis of the time-dependent infrared radiation intensity and the intensity-modulation frequency.

    摘要: A security device, such as a passive infra-red motion detector (1) is provided with a plurality of fasteners (15, 25). One fastener (25) removably fastens a lens (4) to a housing of the passive infra-red detector, such that the lens (4) can be removed from the outside of the housing, whilst the other fastener (15) fastens a front section (2) of the housing to the rear section (3). Both fasteners (15, 25) are transparent/translucent and act as light guides.
