The cooling plate (22) also includes a distributor portion (42) and a collector portion which each have at least one connection (46) for a refrigerant feed line (56) and a refrigerant return line. The wall thickness (D) of the cooling plate (22) in the distributor portion (42) and/or collector portion (44) is greater than the wall thickness (d2) of the second plate part (30).
Abstract: A method for assisting the daytime driving of a motor vehicle, including the steps of: placing at least one variable-transmission screen between the driver of the motor vehicle and the road scene in front of the vehicle, measuring, by means of at least one sensor, the brightness of the road scene in front of the vehicle, and processing the brightness measurement signal to convert it into a signal for controlling the coefficient of transmission of the variable-transmission screen. In one embodiment, the method includes the further step of transmitting the control signal by remote control waves to a receiver fitted to the variable-transmission screen for modulating the coefficient of transmission of the variable-transmission screen as a function of the brightness measured by the sensor.

Abstract: A method is disclosed for reducing the common mode current flowing between the internal ground of an electrical circuit in an automotive vehicle, and the earth, when electric power is exchanged between an electric power storage unit of the electrical circuit and an electric power source external to the circuit. An electronic component is used to apply an electrical quantity as a function of the common mode current to an injection point in the circuit in order to reduce the common mode current. The value of the common mode current is obtained using a measuring device having a magnetic torus configured to be traversed by an electric line by which the electric power is exchanged, the electric line forming a primary winding, a secondary winding, wound about said torus for generating a magnetic flux on the basis of a reference current, and an oscillator for generating the reference current through the secondary winding.
