Abstract: A method and a device for correcting the line scan speed of a display screen according to the luminance of the pixels displayed on screen, wherein the line scan speed is modified with a correction means controlled from a control signal varying like the product of the first and second derivatives of the luminance signal.

Abstract: A shielding chassis is provided with an opening to allow passage of a shielded connector part for connection to a complementary connector part disposed to confront the opening inside the shielding chassis and mounted on a circuit board. The shielding chassis is also provided with an elastic, non-metallic conducting element mounted around the opening, the conducting element contacting a shielding element of the complementary connector part, thereby allowing parasitic currents generated by electromagnetic radiation to flow to ground without passing through the interior of the chassis.

Abstract: A power supply with multiple outputs including at least two power converters, each with multiple outputs, a first output of a first power converter being connected in parallel with a first output of a second converter to provide a first load with current. The power supply further includes a first regulating circuit for delivering to each power converter a command signal that is a function of the current delivered to the first load. The power supply also includes at least one other regulating circuit for delivering to an output regulator (postregulator) connected between each power converter and a load other than the first load, a command signal which is a function of the current delivered by each converter output to the load other than the first load.
