Abstract: A touchless method for registering commands from a display (e.g. reconfigurable display) may include any of various components. The method may use a light sensor in front of or behind the display to detect light reflected by a user's finger approaching a control option displayed on the display. Light used to display images may be provided at a frequency and/or time that can be identified by a processor connected to the light sensor, or can possess some other unique property (e.g. color) which may be distinguished by the processor.

Abstract: The present invention relates to an electrolyte for the electrochemical deposition of palladium or palladium alloys on metallic or conductive substrates. The invention likewise relates to a corresponding electroplating process using this electrolyte and specific palladium salts which can be advantageously used in this process.

Abstract: An apparatus for screening appliances from high frequency interference from the mains supply electrically connected to the appliance has an interference filter being incorporated in the mains plug and comprising at least an induction coil and a capacitor. The capacitors normally used to screen from asymmetric oscillations between the neutral conductor and phase conductor on the one hand and the protective conductor on the other are replaced by a screen of sheeting for the conductor leading from the plug to the appliance. The screen of sheeting is joined to the protective conductor.

Abstract: For the production of low carat rose to gold colored gold alloy coatings there are needed electrolytic baths containing soluble gold cyanide, soluble copper cyanide, potassium carbonate or potassium bicarbonate which produce corrosion resistant coatings of 13-18 carats and no physiologically hazardous cadmium. The baths of the present invention contain, in place of cadmium, 7.5 to 40 grams/liter of zinc as complex zinc cyanide.

Abstract: For the electrolytic deposition of gold alloys there is required a process with which low carat coatings can be deposited which nevertheless have a high resistance to tarnish. Such coatings are obtained from electrolytes which consist of a salt melt and contain gold salts, alkali thiocyanate and salts of one or more alloyings elements as constituents. Preferably the electrolyte contains per liter of salt melt 0.5 to 20 grams of gold, up to 300 grams of Cu, Zn, Sn, Cd, Ni, Ag, Pd, Ru and/or Pt, up to 200 grams of alkali cyanide and/or water.

Abstract: There are needed galvanic baths for the deposition of silver and silver alloys which exhibit a high resistance to sulfur and contain the least possible amounts of alloyed platinum group metals and/or gold. This is attained by using a salt melt as the electrolyte which melt contains a silver salt, alkali thiocyanate and salts of at least one alloying metal. Preferably the electrolyte contains per liter of salt melt 0.1 to 40 grams of silver and 1 to 200 grams of platinum metal and/or gold.
