An evaluation method includes a step of disposing a sensitive color plate between two polarization plates disposed in a crossed Nicols shape, a step of disposing a measurement material that is a transparent material containing a nanowire between any of one polarization plate or the other polarization plate of the polarization plates and the sensitive color plate, a step of making white light incident from a side of one of the disposed polarization plates, a step of observing a color of the measurement material from a side of the other polarization plate, and a step of evaluating an orientation direction of the nanowire from the color of the measurement material obtained by observation.

Various embodiments of systems and methods for calibrating wafer inspection system modules are disclosed herein. More specifically, the present disclosure provides various embodiments of systems and methods to calibrate the multiple spectral band values obtained from a substrate by a camera system included within a WIS module. In one embodiment, multiple spectral band values are red, green, and blue (RGB) values. As described in more detail below, the calibration methods disclosed herein may use a test wafer having a predetermined pattern of thickness changes or color changes to generate multiple spectral band offset values. The multiple spectral band offset values can be applied to the multiple spectral band values obtained from the substrate to generate calibrated RGB values, which compensate for spectral responsivity differences between camera systems included within a plurality of WIS modules.

A testing apparatus for performing an assay, the testing apparatus comprising: a receptacle (2) containing a reagent, the reagent being reactive to an applied test sample by developing a colour or pattern variation; a portable device (1), e.g. a mobile phone or a laptop, comprising a processor and an image capture device (3), wherein the processor is configured to process data captured by the image capture device and output a test result for the applied test sample.

A method of obtaining a plurality of infrared images of a banknote that involves simultaneously illuminating the banknote with infrared light at a first wavelength and infrared light at a second wavelength, capturing an image of the banknote with an RGB camera, obtaining from both a first output channel signal and a second output channel signal of the RGB camera sensor where the intensity distribution of the infrared light at the first wavelength and the intensity distribution of the infrared light at the second wavelength uses a first calibration coefficient and a second calibration coefficient of the RGB camera sensor, producing separate infrared images of the banknote at the first wavelength and the second wavelength from the respective intensity distributions.

The present invention relates to provide, among other things, the methods, devices, and systems that can simply and quickly collecting and analyzing a tiny amount of vapor condensates (e.g. exhaled breath condensate (EBC)).

This disclosure relates to a system and a method for automated recognition of drugs. This disclosure also relates to a system for automated recognition of drugs comprising a hyper-spectral imaging system. This disclosure also relates to a hyper-spectral imaging system configured to automatically recognize drugs by using a neural network. This disclosure relates to training the neural network to identify a drug type (e.g., the name of the drug) based on an image (e.g., normal visible image and/or hyperspectral image) of the drug.

A method of determining the concentration of an analyte in a sample of a body fluid with a mobile device having a camera is disclosed. The camera captures an image of a color reference card and of a reagent test field of an optical test strip having a sample applied to it. A predetermined pixel-based mean tone map correction is applied to the image obtained, which results in a first intensity-corrected image. Local brightness information is derived from the first intensity-corrected image. A mobile device-specific tone map correction is applied to the first intensity-corrected image, taking into account the local brightness information. A second intensity-corrected image is thereby obtained. Analyte concentration is determined based on a color formation reaction of the test field by using the second intensity-corrected image. Optionally, a color correction may be derived and applied to the second intensity-corrected image to obtain an intensity-corrected and color-corrected image.

The invention provides a mild procedure for the functionalization of cellulose and other substrates with a detection reagent such as N-(1-naphthyl)ethylenediamine and is able to achieve much higher functionalization density than previously reported. A paper-based device created using cellulose functionalized according to the invention allowed for much lower detection limits for nitrite in various kinds of water samples than have been seen using paper-based devices. In addition, grafting of N-(1-naphthyl)ethylenediamine to cellulose improved the stability of the N-(1-naphthyl)ethylenediamine in the presence of moisture and light.
