Methods for operating real-time wireless networks enable robust medium access strategies for communicating nodes in the network. A given wireless channel is divided into several sub-carriers, with each node assigned to a subset of sub-carriers. A master wireless node uses different subsets of the sub-carriers to communication with two or more slave wireless nodes simultaneously. The method includes generation of preambles that are robust to interference and multipath conditions. The method also enables communication within a maximum predetermined latency bound.

Method for robust real-time wireless industrial communication

A method and device for detecting the rotation direction of a piston engine, internal combustion engine or piston compressor. The piston engine includes at least one cylinder, a piston movable back and forth in the cylinder, a cylinder chamber formed inside the cylinder which is delimited by an inner cylinder wall and the piston, an inlet channel opening into the cylinder chamber via at least one inlet valve, an outlet channel opening into the cylinder chamber via at least one outlet valve, and at least one triggerable throttling device situated in the inlet channel. To detect the rotation direction in a reliable, timely, and simple manner, the pressure prevailing in the inlet channel is measured when a rotary motion is detected, compared with a predefinable threshold value, and the rotation direction is determined based on the comparison result, the throttling device being closed at least for the pressure measurement time.
