Method of effecting one of several different circuit connections
First Claim
1. Method of effecting one of several predetermined mutual different circuit connections comprising the steps ofinitiating a course of sequentially occurring time windows, or time frames, or time intervals, or time slots in a predetermined sequence, starting from an initial first time slot, includingactuating a switch to start said sequence and maintaining actuation of said switch for at least a certain time corresponding to the first time slot in said initiated sequence, a first preset circuit connection being associated with said first time slot and being prepared upon actuation of the switch;
- temporally associating respective further circuit connections with respective time slots includingpreparing respective circuit connections associated with the respective time slots as sequential time slots occur, circuit connections associated with preceding time slots being disconnected and new circuit connections established whereby, when actuation of a switch persists for a longer period than the interval of said time slot, the circuit connections will shift at a predetermined point of time corresponding to the transition between said first time slot and the sequentially occurred time slot, and subsequently, to the transition between subsequent time slots;
controlling the length of the time course by selecting a predetermined number of the sequential time slots to effect the circuit connection associated with the respective selected one of the time slots;
and indicating each point of time corresponding to a time slot to provide an operator with a preceptible output of the then existing time slot of the course during each instant of time.

Abstract
To permit multiple use of data entry keys, and to effect different circuit connections by a single key, operation of any one of the keys is associated with time slots, or time windows so that, upon operation of anyone of the keys, a course, or sequence of time slots at intervals is initiated, each interval or time slot being temporally associated with a specific circuit connection. The length of the time course, that is, the number of time slots or time intervals is selected by continued operation of anyone of the control buttons, this continuance of operation or operating of another button, entering the then pertaining circuit into the system. An indicator is provided, continuously indicating the then pertaining time slot, and an additional indicator providing a symbolic output representative of the finally established circuit connection. The system may be used with a graphic display, such as a pointer pencil and a screen, the circuit connections establishing representation, sequentially, of electrical components which sequentially appear on the screen at the location indicated by the pointer so that, upon removal of the pointer, the then indicated symbol will persist on the screen, thereby permitting rapid interchange of components and electronically drawing electrical circuit diagrams.

19. System to selectively control connection of one of several circuit connections
in which said several connections are sequentially selectable in a predetermined sequence, comprising a clock source (IC2), providing temporally sequential clock signals, each signal being representative of a time window, or time frame, or time slot; -
a control switch (S1, S2, S3, S4, 41,
50);selection circuit means (IC3, IC15) interconnecting said control switch, the clock source (IC2) and said several circuit connections (IC10,
48) and preparing, sequentially in said predetermined sequence starting from a preset connection, one each of said several circuit connections as the clock source provides temporally sequential clock signals during continued operation of said one control switch;means effecting the one selected circuit connection of said prepared circuit connection; indicator means (LED 1-4;
H1) indicating the specific sequential clock signal which is applied to said circuit selection means at any instant of time to thereby indicate the respective time slot during which said one control switch is operating and;delay means interconnecting the selection circuit means and the switch means and controlling the circuit effecting means to establish, after a predetermined time delay, the selected circuit if said one control switch is operated to terminate continued operation thereof and hence continued supply of clock signals from said clock source. - View Dependent Claims (20, 21)
