Abstract: A device is disclosed for assisting surgical operations inside a vessel, particularly for the minimally invasive explantation and implantation of cardiac valves, comprising an operating structure adapted to be implanted within the vessel, that is adapted to be fixedly and detachably joined to the inner wall of the vessel and is provided with at least one connector and/or support structure for a further instrument required for the surgical operation.

Abstract: A process for separation of dispersions or suspensions by applying an external pressure gradient between a feed reservoir and at least one waste reservoir in such a way that the dispersion flows into a microchannel system. At least one fraction is separated through an opening and via at least one target channel. Different volume flows in a waste channel and a target channel of the microchannel system are set by the selection of an external pressure gradient. The various phases in a dispersion or suspension are separated and concentrated further by a series arrangement of structures of bend arcs. An apparatus for carrying out the process connects the feed reservoir and at least one waste reservoir via a feed channel, at least one bend arc and further channels, respectively, the fractions of the dispersion or the suspension separated substantially within the at least one bend arc.

Abstract: A mobile communication terminal device is disclosed having elements for detecting moisture in the device. These elements include the following precautionary features: a memory for recording a circumstance under which the detection of moisture takes place, a shutdown feature for shutting down the mobile communication terminal device at least partially if moisture has been detected, and a feature for determining two circumstances, namely that the mobile communications terminal has been at least partially shut down as a result of a detection of moisture and that the mobile communication terminal device has been connected to an external power supply and subsequent current is being drawn from the power supply. Once these two circumstances have been detected, a mode is activated by which the mobile communication terminal device is subjected to a heating phase and as a result, in turn, to a drying phase.

Abstract: A method and a circuit arrangement for determining the charging current and the temperature of an accumulator, wherein a part of the charging current is amplified via a transistor that is in thermal contact with the accumulator. An output voltage of the transistor amplifier circuit is measured once at a known temperature for determining a reference value. The output voltage is measured at the temperature to be identified with the charging current switched off and the output voltage is measured at the same temperature with the charging current switched on. The temperature and the charging current are then determined from the reference value, from the voltage with the charging current turned off and from the voltage with the charging current turned on.
