The method comprises the following steps: connecting each client () to a respective one of said servers () and establishing a data communication between each client () and the respective server (), thus forming a multi-client/multi-server network;calculating a figure of merit for rejection (FoMR) for at least one client () con-nected to at least one of said servers (), each figure of merit for rejection (FoMR) determining a probability of rejection of the relevant client () by the server (); rejecting at least one client (), which is connected to a server (), and placingsaid client in a non-connected condition; wherein the client to be rejected is selected on the basis of the figure of merit for rejection (FoMR); connecting the rejected client () to a server () again.

Multi-client/multi-server managing method and system with a routine of rejection of already connected clients for balancing the system

A method and circuit for controlling an HID lamp powered by an HID ballast during warm-up includes gradually increasing the lamp power as the lamp voltage increases. The method includes the steps of calculating a variable reference signal as a function of the lamp voltage and controlling the lamp operating conditions based on the variable reference signal and a feedback signal, to thereby keep the lamp current within a range around a substantially constant target value during warm-up.
