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 smoothes the peak associated with the high intensity light beam produced by the optical element.

Abstract: Disclosed is an apparatus for analyzing fine particles such as blood cells in a fluid such as blood, the apparatus comprising a device for generating electrical signal pulses from the specimen particles which have passed a detecting section such as, for example, a flow pass. The signal pulses are compared with a predetermined threshold, and specific information concerning the specimen particles is detected for a period which is determined on the basis of the signals produced by delaying the signal pulses, from a moment at which the threshold value is exceeded by each signal pulse.
