摘要： A controllable amplifier, which has two symmetrical outputs, at which two output signals mirror-symmetrical with respect to each other are present, is used for amplification of a burst signal. To achieve the largest possible eye opening of the signals to be fed to a comparator, a predetermined d.c. voltage difference for the formation of matched signals is adjusted for both output signals. After this, the arithmetic mean values of the two matched signals are formed and are fed to a second comparator. The output value of the second comparator is fed to an integrator, to which a reference voltage is also fed. In case of a deviation of the mean values of the two matched signals from each other, the amplifier is adjusted in a compensating direction by the integrator.

摘要： For controlling the level of electrical signals a circuit arrangement is formed with two series connected amplifiers. A first amplifier containing a first variable resistor, operates at maximum amplification when a low input signal level is received. A second amplifier comprises a series connection of a second variable resistor and a current-controlled voltage source with two complementary outputs. The outputs of the voltage source are connected to a comparator and a controller with two separate outputs. One of the controller outputs transmits a control signal while the other output simultaneously transmits a blocking signal. A first output of the controller is connected with the first variable resistor, while a second output of the controller is connected to the second variable resistor.

摘要： A cervical support has an inherently stable support body of elastic foam material, provided with a covering of textile material, the free ends of which body overlap each other at the rear in a nape support region of the cervical support and can be detachably connected to each other. The nape support region is of greater height than a front, chin support region of the cervical support. For improved fit against the patient's body, and the relief of pressure thereagainst, the nape support region follows a path which is substantially partially circular or partially elliptical, and merges into jaw support regions which extend symmetrically and in mirror image relationship with respect to an imaginary longitudinal axis connecting the centers of the nape support region and the chin support region. Each jaw support region is of flat S-shape, which at a certain distance from the chin support region, is bowed towards the longitudinal axis.

摘要： An arrangement is provided for digital transmission of information via lines between a line termination (1) of a telecommunication network and subscribers (Tln) connected to the line termination. At least one terminal of a subscriber (Tln) is connected to a network termination (2) via an electric line (L3). The network termination (2) is connected to the line termination (1) via a line (L2) having metallic conductors. The line termination (1) has a voltage source (SV) for supplying power to itself and to the network termination (2) and the subscriber (Tln) terminals. For increased reliability during operation, two separate power supply units (SVE1, SVE2) are arranged in the network termination (2). One of the two separate power supply units (SVE1, SVE2) powers active components of the network termination (2) and the other of the two separate power supply units (SVE1, SVE2) powers the subscriber (Tln) terminals. The two separate power supply units (SVE1, SVE2) are connected to the voltage source (SV) of the line termination (1) via separate lines (A1, A2).

摘要： A cervical support has a substantially inherently stable support member of resilient foam material, constructed to encircle the neck of a patient who is to wear the cervical support. The support member has overlapping free end parts which are releasably connectable to each other. Support elements are insertable into through radial openings of the support member, each support element having a shank having a mushroom-shaped head at one end and a large area head at its other end. The former head can be pressed into a disc or band partially embracing the outer surface of the support member. The support elements can be selectively removed from, or inserted into, the openings to provide local stiffening of the support member as required by the patient's condition.
