Abstract:
Die Erfindung betrifft ein System und ein Verfahren zur Übertragung von Information über einen Stoffstrom. Eine Informationseingabeeinrichtung weist eine Kodiereinrichtung, welche zur Modulation der Konzentration von einem oder mehreren Isotopen, insbesondere Isotopomeren, in einem ersten Stoffvolumens anhand der zu übertragenden Information eingerichtet ist, und eine Aktoreinrichtung, welche zum Einbringen des ersten Stoffvolumens mit der modulierten Konzentration von einem oder mehreren Isotopen, insbesondere Isotopomeren, in den Stoffstrom eingerichtet ist, auf. Eine Informationsausgabevorrichtung weist eine Entnahmeeinrichtung, welche zur Entnahme eines zweiten Stoffvolumens eingerichtet ist, und eine Detektionseinrichtung, welche zur Ermittlung der Konzentration von einem oder mehreren Isotopen, insbesondere Isotopomeren, im zweiten Stoffvolumen eingerichtet ist, auf. Zudem ist eine Recheneinrichtung dazu eingerichtet, die zu übertragende Information aus der ermittelten Konzentration von einem oder mehreren Isotopen, insbesondere Isotopomeren, zu rekonstruieren und auszugeben.

A plurality of connections (A), which are remote and bi-directional, run between a plurality of entities including, for example, a user device (2), a technical assistance centre (3), data traffic processing and management centre (4) and a statistics database (5).
Abstract:
The invention relates to a wireless device for measuring alternating and/or direct current, broadly applicable in industrial processes and in electric power distribution networks. The wireless device for measuring alternating and/or direct current flowing in a measuring wire is characterized in that it contains a flexible conducting element (2) to whose surface at least one wireless passive stress sensor (1) is attached. The element (2) is placed in a homogenous magnetic field, on a plane parallel to the lines of the magnetic field generated by the magnetic poles (3) of a permanent magnet. The flexible element (2) is located in the space between the magnetic poles (3) so that an isolating clearance is maintained on both sides of the element (2).

The fluid meter comprises at least one sensing unit capable of measuring one or more parameters of the fluid inside of the pipe; a telemetric data transmission unit capable of telemetrically transmitting data including a measured fluid parameter to a host terminal and/or another fluid meter; and at least one fluid-driven power source unit capable of generating power from the fluid flow within the pipe and supplying power to the sensing unit and/or the transmission unit.
Abstract:
A system for direct optical control of electronic power semiconductors includes an optical triggering circuit at a first location, wherein said optical triggering circuit generates an optical trigger signal, a power circuit located at a second location remote from the first location, wherein said power circuit includes a photoconductor that is responsive to the optical trigger signal generated by the optical triggering circuit, and an optical cable coupling the optical triggering circuit to the power circuit, and an optical cable coupling the optical triggering circuit to the power circuit. In operation, the power circuit is directly driven by the transmission of the optical trigger signal from the optical triggering circuit to the power circuit via the optical cable. Inductive elements or transformers may be applied to facilitate triggering performance.
Abstract:
A method and device for the transmission of control and/or sensor signals between an electronic control and/or data receiving means and a pneumatic device, which are connected together by means of a pneumatic line of flexible plastic material. For the transmission of the signals using acoustic signals, microwaves or changes in pressure in the gaseous medium in the line the control and/or data receiving means and the pneumatic device are provided with at least one first converter for the conversion of electrical signals into acoustic signals or changes in pressure into electrical signal. Accordingly it is possible for electrical lines, otherwise needed for data transmission, to be dispensed with and data transmission takes place by way of the gaseous medium in the pneumatic line.
