Abstract: A chart includes: a substrate; a first skin reflection patch part that is formed on the substrate and that simulates reflection of near-infrared rays of a predetermined wavelength, in a skin of a living body of a first skin color; and a second skin reflection patch part that is formed on the substrate and that simulates reflection of the near-infrared rays of the predetermined wavelength, in the skin of the living body of a second skin color that is different from the first skin color. According to such a chart, it is possible to properly determine whether or not an imaging environment of an image is suitable for biometric authentication.

Abstract: Apparatus and methods are described for use with a bodily emission of a subject that is disposed within a toilet bowl. One or more light sensors are configured to receive light from the toilet bowl, while the bodily emission is disposed within the toilet bowl. A computer processor detects a set of three or more spectral components that have a characteristic relationship with each other in a light spectrum of a microorganism, by analyzing the received light, and determines that there is a presence of the microorganism within the bodily emission in response thereto. Other applications are also described.

Abstract: A measurement light source is arranged on a rear surface side of a surface at a sample position irradiated with light by an irradiation light source and a detector is arranged on a front surface side of the surface at the sample position irradiated with light by the irradiation light source. A radiation intensity calculator calculates a radiation intensity at each wavelength of irradiation light from the irradiation light source based on a first detected intensity distribution, a second detected intensity distribution, and radiation characteristics of a standard light source. An irradiated photon number calculator calculates the number of irradiated photons at each wavelength of irradiation light from the irradiation light source based on the radiation intensity at each wavelength.

Abstract: A measurement system may comprise an actively illuminated camera system, in some embodiments coupled to a time-of-flight sensor or an array of laser diodes beam split into a plurality of spatially separated lights. The camera system may capture two or three dimensional images, and the light source may comprise semiconductor diodes, such as light emitting diodes. The system includes a processor coupled to non-transitory computer readable medium and configured to use artificial intelligence to make one or more decisions. The processing may also involve artificial intelligence or machine learning techniques to analyze anomalous occurrences, or generative artificial intelligence to interface with a user or improve the performance of camera-based systems. Algorithms may also be used to improve the performance of generative artificial intelligence processing. The camera output may be fused with data from other sensors, and the camera may also capture information about the pose or gestures of a user.

Abstract: Frequency registration deviations occurring during a scan of a frequency or wavelength range by a spectroscopic analysis system can be corrected using passive and/or active approaches. A passive approach can include determining and applying mathematical conversions to a recorded field spectrum. An active approach can include modifying one or more operating parameters of the spectroscopic analysis system to reduce frequency registration deviation.
