Abstract: A communication method in an automation system, wherein the system comprises an access point and client terminals that receive downlink data sent from the access point and send uplink data to the access point, and the data transmission is divided into a master multiple receiver aggregation phase and more than one slave multiple receiver aggregation phases. During the master multiple receiver aggregation phase, the access point aggregates the data to be sent to the plurality of client terminals into one packet for transmitting in the downlink, and during the slave multiple receiver aggregation phases, the access point aggregates data in which errors have occurred when being transmitted during the master multiple receiver aggregation phase into one packet for transmitting in the downlink. The method can have strict control, through the access point and over the uplink and downlink data transmission, thus enhancing the certainty during automation communication and further reducing the cycle time.

Abstract: A method for fabricating a solar cell comprising a semiconductor substrate is proposed where electrical contacting is made on the back side of the semiconductor substrate. The back side of the semiconductor substrate has locally doped regions. The adjacent regions exhibit different doping from the region. The two regions are initially coated with electrically conductive material over the entire area. So that the conductive material does not short-circuit the solar cell, the two regions are covered with a thin electrically insulating layer at least at the region boundaries. The electrically conductive layer is separated by applying an etch barrier layer over the entire surface which is then removed free from masking and selectively e.g. by laser ablation, locally above the insulating layer. The conductive layer is locally removed in the area of the openings of the etch barrier layer by subsequent action of an etching solution.

Abstract: The device for measuring the oxygen content in a gas mixture comprises three flow channels, a main channel, a measuring channel and a reference channel, over which the gas stream is distributed. By using a non-homogeneous magnetic field produced by a magnet, the gas flow is deflected into the measuring channel as a function of oxygen content; at the same time, the flow in the reference channel is reduced. The oxygen content of the gas is determined by means of a flow measurement of the volume flow of gas in the measuring or reference channel by means of resistance thermometers.
