摘要:
A system for monitoring the leak-tightness of a tank, which is filled with a liquid with a lower density than water. The system has a liquid drain pipe, with a container that has a bottom, which is integrated horizontally in the liquid drain pipe with a damming element, which divides the container into a partial area on the supply flow side and partial area on the drain side. A first vibronic measuring device with a first vibrating unit protruding into the supply flow side partial area of the bottom determines whether the density of the medium undershoots a specified limit. A second vibronic measuring device with a second vibrating unit, at a position not exceeding the level of the first vibrating unit, which detects whether the vibrating unit are covered with medium, and with an evaluation unit uses the measured values of measuring devices to determine whether there is liquid from the tank in the container.
摘要:
A device for reactive sputtering, wherein a cathode is applied a discharge voltage for a plasma, and a working gas and a reactive gas are introduced into a sputter chamber. The total gas flow in the sputter chamber is controlled with the aid of a valve, while the ratio of the partial pressures of both gases is kept constant.
摘要:
Methods of and apparatus for preparing gas-filled microspheres are described. Gas-filled microspheres prepared by these methods are particularly useful, for example, in ultrasonic imaging applications and in therapeutic drug delivery systems.

摘要:
A training apparatus includes adjustable resistance means; means for continuously determining an actual configuration of the training apparatus during exercise; means for generating a control signal for an audio device, the control signal being at least partially based on the actual configuration of the training apparatus; and means for outputting the control signal.
摘要:
An apparatus and method for customizing a pre-existing signal that includes at least a video signal. The video signal is received at a video interface, and data used for customizing the video signal is received at a data interface. The data is applied to the video signal to generate a customized video signal.
