There is provided a recognition system adaptable to a portable device or a wearable device. The recognition system senses a body heat using a thermal sensor, and performs functions such as the living body recognition, image denoising and body temperature prompting according to detected results.

Apparatus and methods are disclosed utilizing selected infrared waveband observations to determine selected profiles of interest. A correlative system is constructed and installed at a processor. Thermal and refractivity profiles and structure in a waveband of interest are extracted from observed infrared spectrum single waveband observations received for processing at the processor by the correlative system. The output provides the selected profiles of interest in the waveband of interest. The apparatus includes an infrared receiver and means for measuring angular displacement of received emissions relative to a horizon. The processor converts received emission into equivalent Planck blackbody temperatures across the observations and correlates structure and vertical distribution of the temperatures to provide thermodynamic and refractivity profiles of interest.

A system and method for use in environment with electrical equipment is provided. The system including a housing and at least one light source located on an exterior of the housing. The light source being activated when the system is in a switching mode of operation. At least one sensor is operably coupled to the housing and configured to measure at least one parameter associated with the electrical equipment. A computing device is disposed within the housing and coupled to communicate with the at least one light source and the at least one sensor.

A temperature sensing system for a resistive welding process for a tube performs repeatable temperature measurement using a camera to detect multiple distinct visible light wavelengths even as the ambient environment in the view path changes. Sensed colors in a field of view in the vicinity of a weld are output to a computing element that calculates a corresponding temperature and alerts an operator when the sensed color exceeds a preset color range.

A temperature-measuring device including a transmitter and a receiver. The transmitter is configured to measure the temperature of the material being contained in a container being revolved and/or rotated, and is configured to transmit data including a value of the measured temperature. The receiver is configured to receive the transmitted data. The transmitter is disposed in or on an upper lid detachably secured to the container, so that the transmitter can detect an incident light emitted from the material, and the transmitter can be revolved along with the container.

There is provided a human falling detection system including an image sensor, a thermal sensor and a microphone. The image sensor captures an image frame that is used to identify a face and a height-width ratio of a human image. The thermal sensor is used as a filter for filtering out a living body and captures a thermal image that is used to identify a height-width ratio of a human thermal image. The microphone records a time stamp of an abrupt sound appearing.

A semiconductor substrate measuring apparatus includes a light source to generate irradiation light having a sequence of on/off at a predetermined interval, the light source to provide the irradiation light to a chamber with an internal space for processing a semiconductor substrate using plasma, an optical device between the light source and the chamber, the optical device to split a first measurement light into a first optical path, condensed while the light source is turned on, to split a second measurement light into a second optical path, condensed while the light source is turned off, and to synchronize with the on/off sequence, and a photodetector connected to the first and second optical paths, the photodetector to subtract spectra of first and second measurement lights to detect spectrum of reflected light, and to detect plasma emission light emitted from the plasma based on the spectrum of the second measurement light.

In a detecting device, infrared light is emitted by a first source in a detection target space; second light of a wavelength different from the infrared light is emitted by a second source in a direction different from a direction of the infrared light being emitted by the first source. A reflecting section provided in the direction of the second light being emitted reflects the second light. A light receiver receives infrared light emitted by the first source and reflected by the object, and receives infrared light radiating from the object as a result of the object being irradiated with the infrared light emitted by the first source and being irradiated with the second light emitted by the second source and reflected by the reflecting section. A detector detects the object based on the infrared light received by the light receiver.
