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: The present invention provides a photodetection apparatus having such an arrangement that when signals from the light receiving means in the photodetection device are sampled at a frequency substantially equal to the lowest frequency at which the source of pulse rays is lighted on, one of the noise signal I.sub.nc due to the pulsed illumination as from the fluorescent lamp and the normal output signal I.sub.sc from the laser beam necessarily presents for each of the sampling periods. In the preferred forms, output signal values sampled in the number of cycles corresponding to at least three times the sampling period are compared with each other. If it is judged that one output signal is larger than the other two output signals which are substantially equal to each other, it is determined that the one output signal is a normal output signal I.sub.sc from the laser beam. The one output signal is then taken for the subsequent signal processing step. In the other case, all the output signals are determined to be noise signals from disturbance rays as from the fluorescent lamp, including AC components and will not be taken for the subsequent signal processing step. In such a manner, any adverse affection due to the pulsed AC rays can be eliminated.

Abstract: A process for spectroscopically measuring the content of a component in a liquid mixture involves passing a single optical beam through the mixture without the use of a reference beam and measuring the intensities of transmitted light in two different wavelength bands by means of two adjacent detectors responsive to light in the two wavelength bands respectively. The component being measured absorbs light within one of the wavelength bands. The ratio of the detector outputs can then be related to the component concentration. The principal use of the invention is for in-situ measurement of methanol in gasoline for motor vehicles.
