Abstract: The method comprises the following steps: connecting each client (5) to a respective one of said servers (3) and establishing a data communication between each client (5) and the respective server (3), thus forming a multi-client/multi-server network; 5 calculating a figure of merit for rejection (FoMR) for at least one client (5) con-nected to at least one of said servers (3), each figure of merit for rejection (FoMR) determining a probability of rejection of the relevant client (5) by the server (3); rejecting at least one client (5), which is connected to a server (3), and placing 10 said 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 (5) to a server (3) again.

Abstract: A method for managing a multi-client/multi-server system or network (1) is disclosed. According to some embodiments, the method comprises the following steps: when at least one of the servers (3) receives a request for connection from one of the clients (5), the server (3) calculates a figure of merit (FoM) for the requesting client; the server (3) sends a connection-accepting response to the requesting client (5) with a probability, which depends upon the figure of merit; the requesting client (5) receiving a connection-accepting response joins the server (3) and starts communication therewith.

Abstract: 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.
