Abstract: The invention relates to a method for reproducing a moving picture composed of a succession of images and of monophonic sounds, comprising the steps of: determining spatial location of at least one zone in motion within said moving picture to be reproduced by analyzing successive images; identifying said zone in motion as corresponding to a source (P3) from which sound is originated; and reproducing said succession of images on a display (20) and corresponding sounds on at least one left loud speaker (21) and one right loud speaker (22), while applying to said sounds at least an audio 3D effect as a function of said spatial location.

Abstract: A method for capturing an image with an electronic handheld device (1) equipped with a camera unit (2) and capture means (3) for triggering an image capture, said electronic handheld device (1) further comprising power supplying means (4) connected to said camera unit, and at least one additional component (5) also connected to said power supplying means (4) through a DC/DC converter (11), said method comprising a first step (B) for detecting actuation of capture means (3), and a second step (C) for capturing image once actuation of capture means has been detected.

Abstract: A battery charger has a particularly advantageous application in the field of mobile radio terminal batteries. The charger generates an output voltage and an output current for charging a battery and includes a first regulator, a second regulator for regulating the output voltage to a predetermined value, a detector for detecting the output current, and an activation system which assumes at least two states. In a first state it activates the first regulator when the detector detects a negative or positive output current, and in a second state it activates the second regulator when the detector means detect a substantially zero output current.

Abstract: To solve a problem due to a transient regulation phenomenon (6) at the time of an increase in power demand (1) in a mobile telephone, the regulator is pre-compensated (7) at a time (T′) in advance of a predicted time (T) of the increase in electrical power demand in the mobile telephone. As a result, a power supply voltage (Vr) crossing an operating threshold (3) outside a period of use has no harmful effect on the operation of the mobile appliance.

Abstract: A method of charging a battery in which the end of charging is determined by detecting variations in the battery temperature includes the following steps: entering a charging mode, periodically measuring the battery temperature, measuring the variation in the battery temperature per unit time, comparing the battery temperature variation per unit time to a first threshold corresponding to variation of the ambient temperature and the battery temperature, and in this case terminating the charging mode, and to variation of only the ambient temperature, and in this case comparing the battery temperature variation per unit time to a second threshold corresponding to variation of only the battery temperature and terminating the charging mode.
