Abstract: In one embodiment a method for transmitting data via a serial, asynchronous interface comprises the steps of operating (S10) a device in a text-based receiving protocol mode, receiving (S12), by the device while operating in the text-based receiving protocol mode, via the interface, a request message (Rq) comprising a binary header component and a length indication, entering (S13), by the device, into a binary receiving protocol mode upon receipt of the request message, receiving (S14), by the device while operating in the binary receiving protocol mode, an amount of binary data (D), the amount being specified by the length indication of the request message, exiting (S15), by the device, the binary receiving protocol mode.

Abstract: The present invention describes a method involving measuring of water quality and/or detection of one or more substances in a water flow, said method involving the steps of using a sensor system comprising at least two electrodes, for sending frequency from at least one electrode and receiving a response from at least another electrode, wherein the method involves filtration over one or more frequency ranges in the response, to measure the impedance and using the impedance as an indicator of the water quality and/or for detection of one or more substances in the water flow.

Abstract: A local communication network (16) comprising a first client communication unit (10) and at least one second communication unit (12), and a method of roaming. The client communication units comprise a first interface unit (14) and a second interface unit (18) for connecting to said local communication network (16) and a remote network (20), respectively, and a bridging unit (22). The client communication units are operative in a first mode, in which said first client communication unit (10) bridges traffic between said local communication network (16) and said remote communication network (20) through a first communication path, and in a second mode, in which said second communication unit (12) scans for an alternative second communication path. A roaming control unit (24) determines whether the alternative second communication path is preferred over said first communication path. If this is the case mode of operation is switched and bridging is taken over by said second client communication unit (12).
