Title: Monitoring of amplifier output signal level - measuring voltage and current to eliminate effects of output side interference
Inventor: AIGNER WERNER ING GRAD
IPC: H04B3/46
Filed: 1980-04-18
Abstract: The monitoring system is used in the output stage of a transmitter, the object being to monitor the output signal level and initiate an alarm if it falls below a set value. The method of monitoring is to measure both output stage voltage and current, and use a combination of these to generate a voltage signal proportional to output level. This signal is then compared with a reference and the resulting error used to initiate an alarm. Voltage and current are typically already measured for output impedance matching, thus little additional circuitry is required. The measurement eliminates the effect of disturbing voltages impressed on the output stage from outside the equipment. Where voltage only is measured such disturbances can effectively mask a low signal level and prevent a legitimate alarm being generated.

Patent DE-3109808-A1 (DE)
Inventor: BINZ REINER
IPC: H04Q11/08
Filed: 1981-03-13
Abstract: In switching network units which operate employing an information memory featuring cyclic input and random reading, the number of connections is particularly limited by the fact that during random reading it is not possible to exceed a specific speed. They are normally designed in such a manner that, to a full extent, they can effect both time-wise switching and spatial switching. In these units, the speed restriction during random reading means that the number of connections normally cannot exceed a certain value. Moreover, the facility of time channel conversion to a full extent in units of central switching stages represents an unnecessary expense. Such units are therefore constructed from a plurality of identical modules whose equivalent inputs are connected to one another and into which, during each pulse frame, more PCM words are input than PCM words are stored therein or can be read in random therefrom. Therefore, the time shifts which can be achieved serve primarily for purposes of spatial assignment, although the expense in comparison to the full time-spatial switching units is lower and a larger number of incoming lines can be connected without exceeding the permissible reading speeds.

Title: Method for phase-gating control
Inventor: NUTZ KARL-DIETHER DIPL ING
IPC: H02M5/257
Filed: 1981-07-16
Abstract: The invention relates to a method for phase-gating control and contains, in particular, an improvement of the circuit which is disclosed in DE PS 2629831. In addition to the known circuit, the method according to the invention provides a third current source (power source) which charges the capacitor when a current detection circuit confirms that the switching path is not carrying any current, because of a defect (fault). The third current source charges the capacitor to a reference voltage which is predetermined internally in the circuit, and triggers a retriggering pulse on reaching the reference voltage, which retriggering pulse thus ensures that the switching path is switched through even before the occurrence of the next zero crossing of the mains power supply voltage.
