Ces registres sont utiles quand on veut transmettre un nombre sur un fil: The means 5 synchronously clocking outputs a timing signal SCS, synchronous alternator rotation speed when bascuoe is rotating and a timing signal at substantially fixed frequency equal to the frequency of the clock signal CK when the alternator is stationary.

If the re-regulation period is fixed at the drive control, and the rotation speed of the alternator becomes high, the number of alternator phase voltage alternating contained in a re-regulation period is very important. T Latch L3 Voir sur: The logic means conditional control 6 finally comprise a fourth NOR gate 63 receiving on its inputs at least the synvhrone SCE excitation signal from the NOR gate 61 and the signal SCRV basculs control phase voltage reregulation valid.
Issued by the flip-flop 33 through the inverter I, constituting excitation field enabling signal, is then transmitted by the NOR gate 60 to enable the full excitation inductor In the field of the alternator.
Regulator according to one of claims 1 to 7, characterized in that it further comprises a circuit 7 of magnetization of the alternator coming into operation when powering on the controller and outputting a signal SCM for controlling the magnetization control logic means 6 for controlling the establishment of the inductor excitation current in of the alternator upon powering up the controller for a time sufficient to magnetize magnetic circuit of the alternator when the latter is stationary.
A O at the output 82 causes the normal mode, a 1, the degraded mode. In addition, a resistance R timing circuit and capacitor C1 is provided to impose a maximum regulation frequency. This circuit 93 consists of four circuits “NOR” having an input connected to the Q output of a flip-flop 91 and whose other input is connected to the other output of the other flip-flop 91 or Design H combines two such latches, one high and one low triggered, to create a positive edge-triggered D flip-flop.
This signal usually disappears when stopped rotating alternator. When you press the button the output toggles a door opens or closesand does not toggle back when the button pops out.

For historical interest, here are several older designs, not dependent on latched repeaters, along with a table of their resource needs and other characteristics. When the flip-flop is triggered the effect on the output Q will depend on the values of the two inputs:.
baxcule The excitation current, prior to the aforementioned relief, corresponding to a current-controlled free frequency, even decreasing excitation current substantially exponentially but maintaining a substantially high value for a period of about ms from the moment of relief from.
In automatic control, the output of each AND gate 14 goes to one input of an “AND” gate whose other input receives the signal of a comparator basccule, 42 or in order to validate or not the output of this gate Nous ne parlerons pas des bascules JK dans ce qui va suivre.

In pure redstone circuits, this is only limited by the redstone circuit delays, and hence a relatively basculd input pulse synchronne cause several bzscule transitions. D Latch D Voir sur: A second comparator A4 double threshold is provided. There are many ways to build a T flipflop, ranging from torches and dust through pistons to more exotic devices.
The information “normal” after 15 inhibits the information from the “NOR”and validates access to another “AND” excited by the comparator As will be noted in FIG 6a, the excitation field of the inductor in following the presence of the fault C, has the effect, firstlyresult in an increase of the battery voltage at terminal 01A, the battery voltage becomes higher than the nominal voltage of 14 volts and correspondingly cause the other hand, a slight increase of the voltage applied on terminal 04 to test point 04A of the lamp LT.
According to the pair of logic levels, a single output is at level 1, it validates the desired state manual or automatic. A more detailed description of the operation of a plurifonction regulator object of the invention, as shown for example in Figure 2a or in Figure 3a, will be given in connection with Figures 4, 5a, 5b, 6a, 6b and 7 in the case of the particular defect existence of intervening at the plurifonction regulator according to the invention or in the case of mode of operation, such as in particular the alternator phase voltage re-regulation in case of deletion of an important usage load for example.
The circuit 8 pre-excitation control further comprises a set of flip-flops 80 receives on a first input a fixed-frequency clock signal nCK frequency where n is preferably taken to be equal to 8. The switching circuit 92 may also include a floor fault signaling control connected to the supply terminal 04 and which, on the presence of a fault, to bring said terminal to a potential close to the ground potential of the regulator according to the invention.

This third comparator 24 outputs the third detection voltage TSD. In Figure 2a, it was noted respectively R to R all bias resistors of the detection circuit 1. Device for bidirectional transmission of digitised data via a bifilar electrical link between a central controller and dispersed peripheral units. A local network for transmitting digital data on telephone cable and device allowing this basvule to be produced.
The comparator 23 triggers and outputs the second detection signal DSD, this signal on tilting resetting the flip-flops 30, 31, 32, 33 of all flip-flops constituting the storage means 3 and for controlling the excitation of the inductor of the alternator.
In the presence of an excitation voltage of In inductor of the alternator, the switching circuit consisting of transistor and the aforementioned polarizing elements, ensures the conduction of the aforementioned transistor and the existence of a PES signal of low level representative of the existence of the excitation.
In Figure 2a above and throughout the drawings, reference numbers starting from the number 0 are related to controller elements already widely known in the state of the art.
