Abstract:
The present invention relates to a method for reducing electromagnetic interference radiated from a power supply arrangement comprising a plurality of switching mode power supply units (1, 2) connected to an external device (3), wherein each switching mode power supply unit (1, 2)comprises a ground point (A, B). The radiate electromagnetic interference is reduced by synchronizing a switching frequency of each switching mode power supply unit (1, 2), such that all of said synchronized switching mode power supply units (1, 2) have an identical switching frequency, thereby reducing the difference in electric potential between said ground points (A, B). The present invention also relates to a corresponding power supply arrangement.
Abstract:
The invention provides a system and corresponding method for Concurrent Multi-Person Security Screening CMPSS, arranged for security screening of persons passing a detection area. The screening is arranged to be performed by means of at least a cloth penetrating type of sensor or sensors. Said sensor type or sensor types is/are arranged for producing sensor information to a processing arrangement. The processing arrangement comprises algorithms for threat analysis arranged to use the sensor information as input data and to produce output information to operator panels wherein the CMPSS comprises at least a person tracking subsystem and a subsystem arranged for association of sensor measurements with an appropriate person. When the sensor information associated to a certain person or persons meets predetermined criteria, stored in the processing arrangement, an alert is arranged to be generated and presented at the operator panels.
