Abstract: Method for reducing concentration of iron ions in a trivalent chromium electroplating bath, including: (i) providing the trivalent chromium electroplating bath including trivalent chromium ions, and iron ions, (ii) subjecting at least a portion of the bath to air agitation, to obtain an air-agitated portion of the bath, (iii) contacting the air-agitated portion with an ion exchange resin, to obtain a resin-treated portion of the bath, and (iv) returning the resin-treated portion of the bath to the trivalent chromium electroplating bath, provided that the bath provided in step (i) was or is utilized for electrodepositing chromium on a substrate applying a cathodic current density of 18 A/dm2 or more, after step (iii), iron ions in the resin-treated portion have a lower concentration than in the air-agitated portion, and after step (iv), iron ions in the bath have a concentration below 50 mg/L.

Abstract: A vehicle network for a plurality of interconnected vehicles is disclosed. The network is in the form of a WLAN and has at least two access points. The access points are interconnected in a wireless manner, i.e., without using a wired backbone. Each access point uses the same radio network ID, so all access points form only one single visible network for WLAN clients. A method for establishing the vehicle network is also disclosed.

Abstract: A method is disclosed for establishing and operating a wireless network with a first communication unit, a second communication unit and a mobile communication unit. The first and second communication units are configured in each case as a server and the mobile communication unit is configured as a client. The mobile communication unit acquires connection set-up data of the first and second communication units. A wireless connection is established from the mobile communication unit to the first communication unit. The latter receives an instruction from the mobile communication unit via the wireless connection for configuration as a client of the second communication unit and the mobile communication unit transfers the connection set-up data of the second communication unit to the first communication unit. A wireless connection is then established from the mobile communication unit to the second communication unit.

Abstract: A method and apparatus for regenerating a plating composition which is suitable for depositing at least one first metal on a substrate where the plating rate in the plating composition is very low, where the concentration of the at least one first metal in the plating composition cannot be easily set at a constant level, and where plating-out of the at least one first metal from the plating composition takes place. The method and apparatus for regenerating a plating composition is suitable for depositing at least one first metal on a substrate at a sufficiently high plating rate, while offering the opportunity to easily adjust the concentration of the at least one first metal in the plating composition at a constant level and to provide the plating composition with sufficient stability against decomposition thereof in order to safeguard the regeneration cell from plated-out first metal.

Abstract: A memory module is described which, externally, has the functionality of DDR SDRAMs and contains two groups of conventional SDRAMs. A conversion device provides for the conversion of clock signals, commands, and data. The conversion device contains a changeover switch, a delay locked loop and buffer memory for addresses and commands and also for the data, which are driven in a suitable manner by the delay locked loop.

Abstract: A method and a configuration for the output of bit error tables from semiconductor devices are described. A test control unit reads the bit error table from the memory device following a request from the test apparatus. Then, the bit error tables are transmitted sequentially to the test apparatus for further processing.

Abstract: A method and semiconductor circuit with which a self-test can be generated and tested with commands by which memory banks are interrogated simultaneously includes a processor for carrying out a built-in self-test and generating commands, each for testing only a respective single memory bank, and an additional processor connected downstream forms more complex multibank commands. Such multibank command formation enables a more diverse test of memories and is carried out faster. Principally, such multibank command generation using a combination of conventional single-bank commands has the advantage of not redeveloping a conventional BIST processor from scratch. It is necessary merely to connect a logic circuit downstream, with which conventional commands are combined, to form the multibank commands. As a result, complex self-test commands that simultaneously access a plurality of memory banks can be generated by a very low development outlay.

Abstract: An integrated memory has a memory cell array, which is subdivided into a plurality of separate segments. A first and a second local word line in different segments together form a common global word line. The global word line is decoded via a row decoder. The first and second local word lines are connected to a column decoder in such a way that they can be decoded individually and segment by segment in a manner dependent on a column address. The memory thus allows fast and current-saving activation of a word line.
