Abstract: A method for determining a physical property of a biological sample. The method comprises the steps of: acquiring a set of preliminary calibration signals of a first lot of a reagent using an automatic analyzer with a first photometry module; acquiring a reference set of signals of the first lot of the reagent using a calibration analyzer with a second photometry module; determining a set of module specific components by subtracting the reference set of signals from the preliminary calibration signals; acquiring a lot specific set of signals of a second lot of the reagent using the second photometry module; determining a lot calibration for the first photometry module using the set of module specific components and the lot specific set of signals; acquiring a measurement signal of the biological sample using the first photometry module and the second lot of the reagent; and determining a physical property of the biological sample using the measurement signal and the lot calibration.

Abstract: Presented here are devices and methods to correct ambient light measurements made in the presence of optical elements, such as the curved edge of the cover glass associated with the mobile device. In one embodiment, a film with optical properties is placed within the ambient light sensor to diffuse the high-intensity light beam coming from the optical element. In another embodiment, an aperture associated with the ambient light sensor is disposed to prevent the high-intensity light beam from entering the ambient light sensor. In another embodiment, a processor coupled to the ambient light sensor smooths the peak associated with the high intensity light beam produced by the optical element.

Abstract: There is provided a light receiver which corrects measurement of ultraviolet rays on the basis of measurement of visible right and infrared rays. The light receiver is a light receiver (1) including a first light-receiving element (PD1) and a second light-receiving element (PD2), and a UV cutoff filter (11) in which transmittance of light in an ultraviolet region is lower, in which light after passage through the UV cutoff filter (11) enters the first light-receiving element (PD1), and the first light-receiving element (PD1) and the second light-receiving element (PD2) are switchable between a photodiode (PD_uv) having sensitivity to the ultraviolet region and a photodiode (PD_clear) having sensitivity to a visible light region and an infrared region. Unevenness in incident light is calculated from photocurrents in photodiodes (PD_ir+PD_vis) of the first light-receiving element (PD1) and the second light-receiving element (PD2).
