METHOD IN A CONDUCTING MATRIX AND THAT IN A PREDETERMIND SEQUENCE CHARGE CURRENT TO THE CONDUITS INCLUDED IN SAID MATRIX

Abstract: The present invention relates to a method in a conducting matrix and to a method to display text and/or pictures by using said conducting matrix. The invention is characterized in that current is made to pass the conduits in the matrix pattern in such a way that one or several current coils are generated and which coils are used to create an electric and/or magnetic alternating influence on dot- and/or display elements being turnable, and/or rotatable in relation to said matrix.

Description: Method in a conducting matrix and that in a predeter- mind sequence charge current to the conduits included in said matrix The present invention relates to a method in a conducting matrix and to charge current in a predetermind sequence to the conduits included in said matrix. The main purpose of the invention is to generate magnetic fields to move or activate an object or a substance, either by an interaction using magnetic fields or by an action from eddy currents. By feeding current in a fixed time control and in a settled pattern to a conducting matrix one or several current coils can be generated. This will also make it possible for the generated current coil to "wander" over the surface of the pattern or of the matrix. Another possibility is to allow the current feed to occure at the same time and to different portions of a pattern in such a way that several current coils are momentary generated over the surface of said pattern or said matrix. It is also possible to achiev a combination of wandering and stationary coils in or on said surface. This will in turn make it possible to use the emk generated in each current coil for activating one or several details, e.g. magnetic rocker means, rotor means, or something like that. Thus it is also possible to use a layer of a "luminous" polymeric material, i.e. where light is emitted from the material when influenced by a field. By having each conduit in the matrix connected to a "programmable" current source, predetermind and perhaps changeable patterns of the magnetic fields can be generated in connection to the plate carrying said conduits. E.g. the programmable current source may be connected to a device equipped with a microprocessor and used to recognize voices and being of the kind which transforms a voice into a pattern of magnetic fields corresponding to the spoken words. The conduits in the matrix can be straight and mutually parallel, or arranged in a check pattern, or they can be arched. One application of the invention is intended to flip over dot elements in an information display, which application will be described in closer details below in connection to shown embodiments, where Fig. 1 is a diagrammatic plan view of a conduit matrix used to practice the method according to the invention, Fig. 2 is a diagrammatic section view of dot elements arranged onto a conduit matrix according to fig. 1, and in which magnetic fields are generated by the conduits; Fig. 3 is a diagrammatic plan view of the dot elements and of the magnetic fields generated in connection to the conduit matrix; and where Fig. 4 is a diagrammatic view showing the arrangement of magnetic material in connection to the perphery of the dot. In fig. 1 a diagrammatic plan view of a conduit matrix LM used in the invention is shown. The conduit matrix LM is shown with conduits laid crosswise, as a - h laid vertical and a'- h' laid horisontal. By feeding current in fixed time control through the conduits b - g (V- g') as shown, a central coil with three "turns of a winding" is generated in the conduit matrix. Fig. 2 shows how the dot elements 1 is rotationally journalled and inclined in connection to a support 3, and how the tips 2a of the shafts 2 form axial bearing means towards a plate 4, and which support will carry or in fact constitute said conduit matrix LM. In fig. 3 dot elements with coils 5a - 5c are shown, which coils generate magnetic fields and are arranged in connection to the support 3. Fig. 4 shows the arrangement of magnetic material in connection to the periphery of the dot element 1. The invention is not restricted to be used in connection to the embodiments shown above, but modifications can be done within the scope of the following claims.

Claims: 3 CLAIMS 1. A method in a conducting matrix having conduits arranged in a pattern, characterized in that current is passing through the conduits in the matrix pattern in such a way that one or several current coils are generated, which coils are used to create an electric, and /or magnetic alternating influence on dot and /or display elements being movable, and /or turnable, and /or rotatable in relation to said matrix. 2. A method according to claim 1, characterized in that the current is passing the conduits during fixed time control. 3. A method according to claim 1 or 2 and used to show text and/or pictures, characterized in that dot elements of magnetic or electric conducting material, and movably arranged on a plate, are subjected to an electric or magnetic alternating action by current coils generated by letting current in a fixed time control pass conduits arranged in a pattern on and /or in the plate.
