Abstract: The present invention presents a flexible method for source-based message routing in a network node, particularly also suitable for flexible load distribution of the traffic via a number of link sets terminating directly at an adjacent first network element. The method uses data structures which are often already available in existing systems or are simple to set up, of providing a number of link sets between two signaling points. A two-stage routing process is initiated based on the setting up of a message node, which supports a number of logical networks or signaling point codes. In the first stage a logical network is selected, in which the message is to be routed further. In the second stage the message is routed in the selected network.

According to the method, the electric conductors for mechanically connecting the component to the base body such that an electric connection between the component and the base body is formed when a rigid mechanical connection is established, such that the resistance between the conductors is measured and a resistance value which lies below a predetermined value attests the existence of a rigid mechanical connection.

Abstract: A method for detecting faults, in particular transient faults which cannot be verified which occur in an electrical unit, such as a switching device, by means of a fault counter which, when a fault occurs, counts by a specific first counting value in a first counting direction and which, at specific times, in each case counts by a second counting value in an opposite second counting direction in the situation where no faults have occurred within the relevant time interval. A precautionary alarm signal is triggered on reaching a first counting threshold value in the first counting direction. A second alarm signal, in conjunction with the monitored unit being switched off, is produced on reaching or exceeding a second counting threshold value, which is higher than the first counting threshold value.

Abstract: Drive elements whose physical volume is considerably smaller than piezoelectric actuators for comparable mechanical characteristics and actuation travels can be developed on the basis of the magnetostrictive material Tb.sub.x Dy.sub.1-x Fe.sub.2 (Terfenol). Despite these characteristics, magnetostrictive actuators have until now been used only where no rapid switching processes or actuation movements are required. An actuator of compact construction responds to an electrical drive signal very quickly and can produce large actuation forces. The actuator typically contains N.apprxeq.100 drive elements (1, 1') which are arranged one above the other in the form of a stack, are each of layered construction, and are provided with electrical connections. The drive elements (1, 1') each have a small metal plate (4, 4'), which is arranged between two insulators (2, 2', 3, 3'), and an actuator element (5, 5') which is manufactured from Terfenol.

Abstract: In a magneto-optic method of measuring an A.C. current in a conductor, the plane of rotation of linearly polarized light is rotated through a measuring angle in a Faraday element surrounding the conductor, the angle being a measure of the current strength. This light is divided into two linearly polarized light signals, with polarization planes directed at right angles to each other, which are converted by opto-electro converters into corresponding electrical signals. The two signals are used to form a functional value that represents the temperature. This value is used, together with the first signal, to determine a temperature-compensated measuring signal for the A.C. current.

Abstract: In a method and apparatus for detecting ventricular fibrillation, a measured impedance signal, dependent on the blood volume in the heart, is evaluated, and ventricular fibrillation is assumed to be present if the level of the measured impedance signal falls below a predetermined threshold. This is based on the perception that as the heart fills with blood, given the presence of ventricular fibrillation, the level of the measured impedance signal will decrease. The apparatus also includes circuitry for treating the detected ventricular fibrillation.

A heat shield faces toward the inner region and includes a plurality of bricks being disposed side by side. At least one metal support frame supports the heat shield. The support frame has a plurality of conduits for supplying a cooling gas and a lip encompassing the tube segment and substantially covering the conduits toward the inner region leaving a slit for conducting the cooling gas from the conduits past the lip to the inner region.

Abstract: In a circuit configuration and a method for testing storage cells, all of the bit lines lead to one pair of fault lines which is first precharged with mutually-complementary logic levels. All of the storage cells of a word line are always read-out in parallel relative to one another. In the event of "no fault" the pair of fault lines retains its logic states, whereas in the case of a fault one of the fault lines changes its logic state through switching transistors. This is recognized and analyzed by a comparator circuit in the form of an XOR-circuit or an XNOR-circuit.
