  • Patent number: 8946935
    Abstract: A method for reducing electromagnetic interference radiated from a power supply arrangement. A plurality of switching mode power supply units are connected to an external device. Each switching mode power supply unit includes a ground point. The radiated electromagnetic interference is reduced by synchronizing a switching frequency of each switching mode power supply unit, such that all of the synchronized switching mode power supply units have an identical switching frequency, thereby reducing the difference in electric potential between the ground points. A corresponding power supply arrangement.

  • Patent number: 8905720
    Abstract: An arrangement for monitoring a supply within a platform. A sensor is arranged to generate sample values relating to a fluid characteristic variable, wherein the fluid is fed by the supply within the platform. A processor is arranged to receive a plurality of sample values from the sensor. The processor, is arranged to generate an absolute value of a difference between each of the received plurality of sample values and a subsequent associated sample value, wherein the received sample values are generated during a predetermined time period.
