摘要： Thyristor-controlled series capacitor equipment (CEQ), intended for connection between an ac network (NET) and a converter (CONV), connected thereto, for conversion between alternating current ((IT) and high-voltage direct current (Id), with a controllable semiconductor valve (TYSW), has control equipment with control means (32) which, in dependence on a synchronization signal (&PHgr;SYNC), form firing pulses (TP1,TP2) for control of the semiconductor valve. The converter has a control device (CTR1) which forms a control-angle order (&agr;-ORD) for phase-angle control of the converter, related to the phase position for a voltage (U12) at a chosen connection point (J2). The control equipment (CTREQ) comprises phase-correcting means (52, S4) which form the synchronization signal in dependence on a voltage-phase signal (&PHgr;U)) supplied thereto and containing information about the phase position of said voltage, and on a control-angle signal (&agr;) supplied thereto and containing information about the control angle of the converter.

摘要： In a computer system the instruction decoding unit for translating program instructions to microcode instructions operates dynamically. Thus the unit receives state signals indicating the state of the computer, such as a trace enabling signal, influencing the translation process in the instruction decoding unit. These state signals are added to the operation code of the program instruction to be decoded, the operation code of the program instruction thus being extended and used as input to a translating table, the extended operation code of the program instruction being taken as an address of a field in the table. The addresses and thus the contents of the fields addressed for the same operation code of a program instruction can then be different for different values of the state signals. Thus generally, the state signals cause the instruction decoder to change its translating algorithm so that the decoder can decode an operation code differently depending on the state which the signals adopt. The dynamic decoding can for a trace enabling signal be used for switching on and off a trace function. In the normal case, when tracing is not desired, no microinstructions supporting the trace function have to executed and thereby the performance and in particular the speed of the computer system will be increased.

摘要： A direct electrostatic printing device and method for printing an image to an information carrier with improved harmonization of the printed density from a plurality of rows of apertures. The harmonization of the printed density from apertures from different rows is accomplished by an improved method of controlling the amount of pigment particles transported through the apertures of each row. The method takes into account which row the aperture belongs to and how the rows are positioned in relationship to the pigment particle feed.

摘要： Control equipment (CE2) generates an ordered value (AOL) of a control angle (.alpha.) in dependence on a limiting signal (AMAXL), capable of being influenced, for a converter included in a series-compensated converter station. A calculating value (AMARG) of a control angle is calculated continuously according to a predetermined relationship (M0, M1, M2, M3) which at least approximately resembles a relationship according to which, at a commutating margin (.gamma..sub.m) equal to a preselected value (.gamma..sub.p), said control angle is a function (F0) of a current (Id2) and a voltage (Un2) in the converter station and the limiting signal is formed in dependence on the calculating value.

摘要： The present invention is directed towards providing event-triggered communication in a half duplex communication environment of a wireless communication network (10). A first end terminal (12) sends a selection of an end terminal (14) in a group of terminals to act as an event notifying device to a server (22). The event notifying device (14) compares an event with a threshold and sends an event notifier to the server if the event exceeds the threshold. If it receives the event notifier, the server prioritises data from the event notifying device over ongoing communication sessions for other devices in the group, receives data from the event notifying device associated with the event notifier and transports data indicative of the event to other devices of the group, in order to inform them of the event.
