Abstract: The present invention relates a device for analysing bodies, preferably cells, suspended in a fluid, the device comprising: a microfluidic channel arranged for allowing the fluid containing the bodies to flow therethrough, an imaging means arranged so as to obtain optical information of the bodies as they are flowing through the channel, an analysis means which uses the optical information obtained by the imaging means to obtain a phase distribution map of the spatial distribution of the phase shift of light as it passes through the bodies.

Abstract: A device for generating pressure waves of high amplitude, in particular for boiler cleaning, has a pressure-resistant container (21, 40) with a combustion chamber (121) inserted therein, which can be filled with a flowable burn-off material via supply lines. The pressure-resistant container has a discharge opening (306) for the directional discharge of gas pressure generated by ignition of the combustible material. A piston (70) closes the discharge opening, can release it for directional discharge and can be pushed back into the initial position by a spring device.

Abstract: A fastening device for a cleaning device by introducing pressure waves through a hollow nozzle into a boiler to be cleaned through an opening in the boiler wall has a housing body, which can be fastened to the boiler wall with the aid of a fastening flange on the boiler side, the hollow nozzle being concentric with the opening in the boiler wall and orthogonal to the boiler axis. Damping units are arranged at regular angular intervals around the hollow nozzle in the longitudinal direction thereof and are each fastened with one free end to the boiler-side fastening flange and with the respective other free end to the housing body. When the pressure waves are triggered, the housing body is resiliently retained in the longitudinal direction away from the boiler and brought back into the initial position.

Abstract: Arrangements and methods for controlling communication connections in a packet-oriented communication system are provided. A communication master computer controls communication connections based on exchanged signaling messages of a respectively preset communication protocol and a service provider unit supplies communication services for establishing and controlling connections based on bi-directional communication service calls with a service user unit. An interface to couple the service provider unit with the service user unit is provided. Additionally an interface to couple the master computer with the service provider unit is provided. Parameters are extracted from a received signaling message for assignment to a communication service.

Abstract: A device for moving an X-ray apparatus embodied in the form of a C-bow (9) in a controlled manner, the C-bow (9) being mounted on a pedestal (31) provided with motor-driven rollers (3) controllable in their direction of travel in such a way that it is displaceable in parallel in relation to at least two axes (18;19) and rotatable relative to three axes (18; 19, 21), each movement of the C-bow (9) with respect to a coordinate system (29) which is stationary relative to the room being carried out via controllable drive devices (6;7;37;38). These drive devices (6; 7; 37; 38) are controlled either by means of a control device (39;48) or via a computer (23), said control device being operated either via a sterile control console or by voice control. Any positions and projections of the C-bow (9) that have once been adjusted may be stored in the computer (23), so that a desired position and projection may be reproduced again.
