A method for applying a carbon-based reflective overcoating on a grazing incidence optical unit comprising a substrate and a coating of a high-density material chosen from the group comprising gold, platinum, iridium, palladium, rhodium, ruthenium, chrome and nickel or a low-density material such as carbon or B4C; the method comprises the step of treating the optical unit with a solution or gaseous phase containing at least one polymer precursor material to create the overcoating through absorption of the polymer material on the coating.

A power supply system can include an electrical battery for supplying electrical load using pulse discharge; and a control unit to control the electrical battery to pulse discharge by periodically switching between a discharge state of the electrical battery, when the electrical battery is connected to the electrical load, and a rest state of the electrical battery when the electrical battery is disconnected from the electrical load. During the pulse discharge, the control unit can control a power source for supplying an injection current to the electrical battery during a rest period when the electrical battery is in the rest state. The control unit can further determine the voltage of the electrical battery during the rest state, and when the voltage does not meet a threshold value increase the duration of the rest period, until said threshold value is reached. Other systems, methods and apparatuses are described.

Pulse discharge system

A power supply system for supplying an electrical load using a pulse discharge arrangement. The power supply system comprises a first electrical battery for supplying said electrical load, a control unit configured to control the first electrical battery for periodically switching between a discharge state of the first electrical battery and a rest state of the first electrical battery, said control unit being further configured to control a power source for supplying a first charging current to the first electrical battery during a rest period when the first electrical battery is in the rest state.

Power supply system

A method and a bath for protecting a Zn or Zn alloy surface against the corrosion and oxidation and for improving the wettability characteristics of a Zn or Zn alloy surface with a Sn solder alloy. The method is particularly useful in the manufacture of electronic components, when the deposition of a thin layer of Zn or Zn alloy is needed before the deposition of the Sn alloy (particularly Pb free) to improve the solderability characteristics of the Cu surface.
