A method of determining concentration of an analyte in a body fluid uses a mobile device having a camera and an ambient light detector. The ambient light detector has an ambient light sensor and/or an additional camera. An ambient light check is performed. In the ambient light check, ambient light is used to determine an item of ambient light information. If a validity criterion is determined to be met, the concentration of the analyte is determined by evaluating an image of at least a part of a reagent test region of an optical test strip having a sample of body fluid applied thereto. The image is captured by the camera. A mobile device, a kit, a computer program and a computer-readable storage medium are also disclosed.

A system for outputting a representation of a wound in tissue comprises a housing configured to removably receive at least a portion of a wireless communication device. At least one light source coupled to the housing is configured to emit excitation light to illuminate a target which includes at least a portion of the wound. A power supply contained in the housing is configured to provide power to the light source. A non-transitory computer-readable medium stores a program executable to cause the performance of operations comprising detecting signals responsive to illumination of the target, outputting the representation of the target based thereon, storing data relative to one or more target surface parameter based on the detected signals, and displaying the representation. The signals correspond to at least one of endogenous or exogeneous fluorescence, absorbance, and reflectance from at least one biological component in and/or on the target.

A method for detecting at least one property of a plant product, the method including: directing source light including ultraviolet (UV) light at UV wavelengths and polarized visible and/or near-infrared (VIS/NIR) light at VIS/NIR wavelengths onto a region of the plant product; blocking the polarized VIS/NIR light of the source light, and blocking polarized specular reflection from the region of the plant product, from being transmitted to a visible and/or near-infrared (VIS/NIR) spectrometer; and transmitting a portion of emitted light caused by fluorescence and/or diffuse reflection from the region of the plant product to the visible and/or near-infrared (VIS/NIR) spectrometer.

A method of measuring the color of a surface may include a device positioned above the surface. The device may include an optical sensor and a display screen. The optical sensor measures visible light level reflected from the surface in a plurality of spectral channels. A plurality of patterns are sequentially displayed on the display screen. The optical sensor is used to measure light reflected by the surface during display of each pattern. A value is determined for the distance from the optical sensor to the illuminated region for a first local maximum of intensity of the measured light reflected by the surface. A location in a color space corresponding to a color of the surface or a reflectance spectrum of the surface is determined based on the visible light level in each spectral channel for the value of the distance corresponding to the first local maximum.

The present invention discloses a method of infrared spectrometric measurement of tunnel gas employing a gas measurement system including a gas collection unit, a gas analysis unit and a positioning indication unit for measuring the gas in the tunnel. The method performs sequential steps of installing the gas measurement system, starting the positioning indication unit for positioning one of the detection regions in the tunnel space, sampling the gas in the detection region through the gas collection unit, analyzing the gas by the gas analysis unit, generating a gas analysis result, and determining whether all of the detection regions are completed. With the newly designed gas collection unit in collocation with the gas analysis unit and the positioning indication unit, the method of the present invention does not only fast install the whole gas measurement system, but also well understands all preliminary information related to the harmful gas in the tunnel like sort and concentration, thereby instantly taking correct measures.
