Abstract: A sensor data transmission system includes a central processor, first and second sensor assemblies, and first and second conductors. The sensor assemblies each include a sensor, a processor and a relay. The sensor is configured to detect a condition. The processor is configured to receive a condition detected signal from the sensor and open the respective relay at least once indicative of the condition and within a pre-determined time interval. The first conductor is electrically in contact with the processors of the first and second sensor assemblies and is interposed by the relay of the second sensor assembly. The second conductor is electrically in contact with the central processor and the processor of the first sensor assembly and is interposed by the relay of the first sensor assembly.

Abstract: The invention concerns a method for the production of single crystal aluminium nitride doped with scandium and/or yttrium, with scandium and/or yttrium contents in the range 0.01 atom % to 50 atom % with respect to 100 atom % of the total quantity of the doped aluminium nitride, characterized in that in a crucible, in the presence of a gas selected from nitrogen or a noble gas, or a mixture of nitrogen and a noble gas: a doping material selected from scandium, yttrium, scandium nitride or yttrium nitride or a mixture thereof and a source material formed from aluminium nitride are sublimated and recondensed onto a seed material which is selected from aluminium nitride or aluminium nitride doped with scandium and/or yttrium.

Abstract: The present invention relates to a process for preparing aldehydes or ketones using an alkali metal hypochlorite or an alkaline earth metal hypochlorite in the presence of a ruthenium catalysts.

Abstract: The present invention relates to a process for the oxidation of alcohols to aldehydes or ketones in the presence of heterogeneous, inorganically supported ruthenium catalysts using aqueous alkali metal or alkaline earth metal hypochlorite solution as oxidant.

Abstract: In a fitness machine with a carriage (2) which is mounted in a movable manner on a carrier element (1) and is intended for at least one person, the carriage (2) can be made to move in a reciprocating manner on the carrier element (1) by means of at least one actuating element (7.1, 7.2).
