Abstract

A manually operable random generator has a housing defining an interior space. In the interior space there are at least three balls of the same spherical volume. The interior space has a volume which is greater than the total volume of all the spheres. The housing has a receiving area accessible by the balls and which has a shape and size so that the receiving of several balls is possible.

Description

The invention relates to a manually operable random generator.
There are numerous games whose gameplay depends on the setting of numbers or symbols determined by dice. Unfortunately, there are narrow limits as far as the options are concerned, although there are dices in different shapes and configurations.
More and more games, raffles, sports exercises and the like work with larger number spaces and possibly with additional numbers or symbols. Here one requires either the use of a number dice and a symbol dice, or one resorts to electronic or computer-based solutions.
The die principle has already been realized in other forms, such as by centrifugal dices, turntables and many more.
It is an object to provide a versatile random generator, which should be actuated manually and which covers a greater number- and/or symbol range than previous dices.
It is also the object to provide a manually operable solution, in which the “diced” result is not immediately visible to third parties.
In addition, it is an object to propose a solution that can be miniaturized and/or automated.
According to the invention a manually operable random generator, whose features are given in claim 1, is provided.
Such a random generator is characterized in that it comprises a housing defining an interior space and in which at least three spherical bodies are enclosed which each have the same body volume. The interior space has a volume that is greater than the total volume of all bodies, so that the bodies can freely move within the interior space. The housing includes a receiving area, which is accessible from the interior space of the body and which is capable of receiving a plurality of bodies.
Preferably, “real” balls or slightly flattened balls or elongated bodies are used as spherical bodies.
Preferably, the spherical bodies are received at several predefined positions in the receiving area.
Preferably, the spherical bodies are received in the receiving area on at least two planes directly above one another, wherein the spherical bodies are close-packed in this case.
Preferably, the receiving portion comprises a plurality of receiving openings, which are accessible for the spherical bodies from the interior space and which each have a shape and size that each enables the receiving of one of the spherical bodies. Here the spherical bodies are received separately from each other in one of the receiving openings.
The random generator of the invention can have more receiving openings than spherical bodies, an equal number of receiving openings and spherical bodies or fewer receiving openings than spherical bodies.
The random generator of the invention can be designed as a microsystem (e.g. a micro-optoelectro-mechanical systems (MEMS)).
The random generator of the invention may be particularly advantageous in connection with games, raffles, lottery, sports exercises and the like.
The random generator of the invention, however, can also be used in connection with scientific experiments, involving a random selection or a random sampling. An example is the so-called Monte Carlo simulation. The random generator can also be used for randomly selecting people, such as in the context of representative surveys. The random generator of the invention is also applicable in the context of stochastic lectures and as demonstrator.
The random generator of the invention, preferably as a micro-system, may also be used in conjunction with encryption methods, for example, to improve the encryption or to make it more secure.
It is an advantage of the invention that the random generator works mechanically and thus is non-deterministic. Software-based random generators, however, always are deterministic.

Further details and advantages of the invention will be described hereinafter with reference to embodiments and with reference to the drawings.

It concerns mechanically functioning random generators 10, which are equipped with multiple spherical bodies. Spherical bodies are understood to have no major or distinct contact surfaces (or layers) so that the spherical body can move freely inside the random generator 10 and can be arranged or stored in a receiving section 12 or in special receiving openings 14.1-14.m (m is an integer greater or equal to 3). It is important that the bodies do not hang in the interior space 13 of the random generator 10 or hang together.
Preferably, “real” balls or slightly flattened spheres, such as for instance (elongated or flattened) spheroids are used as spherical bodies. A “real” ball according to the invention is defined by the set of all points of a space which have the same distance with respect to a fixed point. In the following “real” balls 1.1-1.n (n is an integer greater than or equal to 3) are shown, but this is not intended to be limiting. Reference is made to the sphere volume, although the volume of a flattened or elongated body, strictly speaking, can not be called a spherical volume. In the introductory part and in the claims, therefore, where necessary, the expression body volume is used.
A random generator 10 of the invention is characterized in that it comprises a housing 11 defining an interior space 13 and in which at least three balls 1.1-1.n of equal spherical volume VK are enclosed. The interior space 13 has a volume VI, which is greater than the total volume of all spheres (i.e. VI>n*VK), so that the balls 1.1-1.n can move freely within the interior space 13. The housing 11 comprises a receiving section 12. In some of the embodiments (see FIGS. 1A, 1B, 2, 3, 4A, 4B, 5, 6, 9A, 9B) the receiving section 12 comprises several receiving openings 14.1-14.m, which are accessible for the balls 11 side 1.1-1.n from the inside 11 and which each have a shape and size, to allow the receiving of one of the balls 1.1-1.n.
A first embodiment of the invention is shown in FIGS. 1A and 1B. FIG. 1A shows a schematic, perspective transparent view of a first random generator 10 of the invention. The random generator 10 has a cubic shape and there are four balls (n=4) and four receiving openings (m=4). I.e. in this embodiment, the following applies:
n=4; m=4 and n=m
Even this simple embodiment of the invention permits—depending on equipment with balls 1.1-1.n—covering different number—or symbol ranges.
The following primarily number ranges are referred to and the embodiments are related to different number ranges. However, the invention allows numerous variations by, for example, working with symbols instead of numbers, or in that a particular scheme S1 (see e.g. FIG. 11) defines a basis.
If the first embodiment of the invention is equipped with a single ball 1.1, then:
n=1; m=4 and n<m
In this case, exactly four different positions are possible, which can be taken by the ball 1.1. Thus, there are four possibilities, as illustrated by the following simplified table (the white circles represent the position of the ball 1.1 in the respective receiving opening 14.1-14.4, designated on the right hand side). Such an embodiment may thus replace a conventional pyramidal 4-sided dice.

Possibilities	1	2	3	4	Receiving openings

If the first embodiment of the invention is equipped with two identical balls 1.3, 1.4, then:
n=2; m=4 and n<m
In this case, there are six possibilities, as illustrated by the following simplified table 2 (the white circles represent the positions of the balls 1.3 and 1.4 in the receiving openings 14.1-14.4, designated on the right hand side). Such an embodiment may thus replace a conventional dice with six sides.

Possibilities	1	2	3	4	5	6	Receiving openings

In most embodiments of the invention, a defined orientation of the visible ball field is important in order to be able to assign unique numbers and/or symbols.
A unique orientation can be set in all the embodiments by means of a label or a symbol (Sy) on the housing 11 of the random generator 10. But one can also agree that for instance the side of the visible ball field is deemed the top side where one of the balls (e.g. the black sphere 1.2, if one is used) is in the uppermost position.
In the FIGS. 1A and 1B, an arrow Sy is placed as a symbol on the top of the housing 11, so as to determine the orientation.
By way of another example, which is specifically shown in FIGS. 1A and 1B, the flexibility of the first embodiment of the invention will be shown. When the first embodiment of the invention is equipped with two identical white balls 1.3 and 1.4, a grey ball 1.1 and a black ball 1.2, then:
n=4; m=4 and n=m.
In this case, twelve opportunities arise, as illustrated by the following simplified table 3 (the different circles represent the positions of the balls 1.1-1.4 in the receiving openings 14.1-14.4, designated on the right hand side).

Possibilities	1	2	3	4	5	6	7	8	9	10	11	12	Receiving openings

In the situation shown in FIG. 1A, the balls 1.1-1.4 sit in the receiving openings 14.1-14.4 in the constellation, which is referred to in the above table 3 as possibility 1. In the situation shown in FIG. 1B, none of the balls 1.1-1.4 sits in a receiving opening 14.1-14.4. By manually agitating the random generator 10, the balls 1.1-1.4 can be mixed and brought into the receiving openings 14.1-14.4.
Preferably, the mixing in all embodiments is done so that the balls 1.1-1.n cannot be seen, to prevent manipulation. Therefore, the housing 11 in all embodiments is preferably opaque or only partially transparent (for instance in a window area 18 (see FIG. 8) or in the area of the receiving openings (see FIG. 5).
Referring now to FIG. 2 a second embodiment of the invention is described. FIG. 2 shows a schematic sectional view of the second random generator 10 of the invention from the top. This embodiment of the random generator 10 has a cubic shape, too. It now has m=9 receiving openings 14.1- to 14.9. In FIG. 2 one looks from above into the interior space 13 of the housing 11, and may see the receiving area 12 with the m=9 receiving openings 14.1-14.9. To prevent that there are “dead spots” in the receiving area 12, in which a ball may set, the receiving area 12 is preferably sloped. In FIG. 2, the receiving area 12, for example, consists of four triangular segments D1-D4, which define in the area of the common contact point (located here in the middle) a low point. The low point here is exactly centred underneath the receptacle opening 14.5.
If the second embodiment of the invention is equipped with a single ball 1.1, then:
n=1; m=9 and n<m
In this case, exactly nine different positions are possible which can take the ball 1.1. Thus, there are nine possibilities.
If the second embodiment of the invention is equipped with a white ball 1.3 and a black ball 1.2, then:
n=2; m=9 and n<m
In this case, there are at least 9*8=72 possibilities. A scheme S1 is shown in FIG. 11 where by means of a special assignment the numbers 1 to 64 are allocated to the different images (constellations of spheres), which may arise. Further possible pictures, which are assigned no numbers here, can be allocated special functions (Joker fields, fields of action, etc.).
The random generator 10 of FIG. 2 is as flexible if it is equipped with a grey ball 1.1, a black ball 1.2 and seven neutral balls (eg white). The neutral (eg white) balls then take in the example described in the last paragraph the blanks positions. I.e., this embodiment has no empty receiving openings 14.1-14.m, but neutral (eg white) balls that serve as placeholders.
The random generator 10 of FIG. 2 is much more flexible if it is equipped with a black ball, a white ball, three red balls and four green balls (i.e. n=m=9). Such a random generator 10 offers 3168 possibilities.
FIG. 3 shows a schematic sectional side view of a portion of a third random generator 10 of the invention, wherein the receiving region 12 comprises a structured top side 12.1 and three receiving openings 14.4, 14.5, 14.6, which actually all are occupied with one ball 1.1, 1.2, 1.n. The structured top side 12.1 has inclined surfaces which are each so arranged and inclined that the balls 1.1, 1.2, 1.n necessarily roll into the receiving openings 14.4, 14.5, 14.6. In order to ensure after shaking or moving the random generator 10 that the balls 1.1, 1.2, 1.n are located in the receiving openings 14.4, 14.5, 14.6, the housing 11 (not shown) of the random generator 10 may be equipped with a plunger 54, which holds the balls 1.1-1.n after a displacement movement P2 in the receiving openings 14.4, 14.5, 14.6. The plunger 54 can be moved manually up or down, for example, from outside of the housing 11. When it is moved downward, the balls are 1.1-1.n trapped or clamped and one can for example turn the random generator 10 to see which balls 1.1-1.n are in which receiving openings 14.4, 14.5, 14.6.
FIG. 4A shows a schematic sectional side view of a portion of a fourth random generator 10 of the invention, wherein the receiving portion 12 is provided with means 50 in form of a slide 53. The slider 53 is in an open position in FIG. 4A. In this open position, a ball 1.1, 1.2, 1.n might access one of the receiving openings 14.4, 14.5, 14.6 because the slider 53 is provided with through holes 51 of a corresponding size. Preferably, the top 53.1 of the slider 53 is structured in all embodiments (such as the upper surface 12.1 of the receiving area 12 in FIG. 3), that the balls 1.1, 1.2, 1.n necessarily roll in the receiving openings 14.4, 14.5, 14.6. By moving the slider 53 (as indicated by the arrow P1), the slider 53 can be transferred to a locking position. FIG. 4B is a schematic sectional side view of the fourth random generator 10 of FIG. 4A, wherein the slider 53 is in the locking position. In the locking position, the balls are 1.1-1.n caught or stuck, and one can for example turn the random generator 10 to see which balls 1.1-1.n are in which receiving openings 14.4, 14.5, 14.6.
FIG. 5 shows a schematic sectional side view of a receiving portion 12 of a fifth random generator 10 of the invention, wherein the receiving port 14.m is provided with means 50 in the form of magnets 16, in order to hold a ball 1.n in the receiving opening 14. If permanent magnets 16 are used here, then the balls 1.n should be metallic and the magnetic field strength should be chosen so that the balls come off from its locked position when the random generator 10 ss shaken or tapped on a table. However, embodiments are possible in which the magnetic effect is caused by the movement or displacement of an element of the housing 11.
Preferably, the receiving openings are 14.1-14.m designed in all embodiments so that one can see from the bottom, which balls 1.1-1.n are in which receiving openings 14.1- are 14.m. The receiving openings 14.1-14.m can therefore, in all embodiments comprise windows, view holes or regions or lenses. The receiving openings 14.1-14.m may also be surrounded by a transparent material in all embodiments. In FIG. 5 is indicated by way of example, that the receiving opening 14.m is provided with a window 15.
A schematic view of a sixth random generator 10 of the invention is shown in FIG. 6 from below, which has a cubic shape and nine receiving openings 14.1-14.m (with m=9), with eight of the receving openings 14.1-14.m being occupied with balls 1.1-1.n in the moment shown. The holes of the receiving openings 14.1-14.m have a diameter which is slightly smaller than the maximum diameter of the balls 1.1-1.n. The diameter of the balls 1.1-1.n is shown in FIG. 6 by dashed circles. The receiving opening 14.6 was deliberately shown for clarity empty (eg the corresponding ball is still in the interior space 13 of the housing 11). Due to the fact that the receiving openings 14.1-14.m have a diameter which is slightly smaller than the maximum diameter of the balls 1.1-1.n, the balls 1.1-1.n do not fall out of the housing 11. The balls 1.1-1.n are however almost completely visible if one looks at the random generator 10 from the bottom.
FIG. 7 shows a schematic perspective transparent view of a further random generator 10 of the invention having a cube-shaped and including a hinged cover 11.1 with a mirror surface 17. In FIG. 7 is indicated in purely schematic form that by looking at the mirror surface 17 a ball (shown here as a circle K in the receiving area 12) is visible from the outside. The reflection of the circle K is denoted here by K*. In order to be able to open the cover 11.1, a pivot axis A1 is provided on the housing 11 in the region of an edge, as indicated schematically in FIG. 7. So that the lid 11.1 remains closed during shaking of the random generator 10, a mechanical or a magnetic closure may be provided (not shown).
FIG. 8 is a schematic, perspective transparent view of another random generator 10 of the invention, which has a cubic shape and which includes a window panel 18. Also here the receiving area 12 is at the bottom of the cube-shaped housing 11. In order to be able to see the balls 1.1-1.n, the said window panel 18 is mounted on the top of the housing 11. From above, one can see into the interior space 13 and can recognize the arrangement of the balls 1.1-1.n in the receiving area 12.
It is obvious that the housing 11 can also have any other shape. It is only important that the receiving area 12 is substantially flat so that the balls 1.1-1.n can rearrange easily in the receiving openings 14.1-14.m. It is also important that there are no areas in the interior space 13, in which the balls 1.1-1.n can be stuck.
Particularly preferred is an embodiment of FIG. 9A. FIG. 9A shows a schematic sectional view of a further random generator 10 of the invention, which has a (partial) spherical shape and its receiving area 12, shown in section, comprises five receiving openings 14.1-14.5. In practice, this random generator 10 may have nineteen receiving openings 14.1-14.m, as shown in FIG. 9B.
A further embodiment of a random generator 10 of the invention is shown in FIGS. 10A to 10D. FIG. 10D is a schematic side view, where the balls 1.1-1.n (with n=17) are arranged in three overlapping layers. FIG. 10A shows a sectional view through the lower portion 11.3 of the housing 11 together with seven balls contained therein. FIG. 10B shows a sectional view through the middle layer with three balls, and FIG. 10C shows a sectional view through the upper layer with seven balls. The housing 11 is hexagonally shaped in the lower housing portion 11.3 and has a dimension such that the balls are arranged in a close packing (close together) at three levels.
In order to be able to open up a number or symbol space, at least one of the n=17 balls must be different from the other balls. Here a black ball 1.2 is used, which is at the bottom left of the bottom layer in the example shown. This constellation could for example be assigned the number 6.
This embodiment allows to create the following constellation of a random generator 10 with seventeen different possibilities, if the random generator 10 is fitted with a black ball 1.2 and 16 neutral balls:
n=17; m=17 with n=m
The embodiment of FIG. 10 can also be modified so that the lower housing area 11.3 is square shaped rather than hexagonal, and that in the lower layer four balls, one ball above this and again four balls can lie on top.
FIG. 11 shows an exemplary counting scheme S1 that can be used in conjunction with a random generator 10 of the invention, which comprises the nine receiving openings 14.1-14.m (m=9) and which is fitted with a white ball and a black ball. In the illustrated counting scheme S1, the position of the white ball is represented by by a white “smiley” and the position of the black ball a black “smiley”. The other fields of the counting scheme S, or the corresponding receiving openings 14.1-14.m may either be empty (if only the white ball and the black ball are used, i.e., when the following applies: n=2), or neutral balls may be in these positions (in this case: m=n=9).
If now, after the shaking of the random generator 10, the white ball is in the junction box of the first column and the first row and the black ball is in the junction box of the second column and the first row, the constellation shown in the first quadrant Q1 top left of the counting scheme S1 results. This configuration may be associated with, for example, the number “1”. If the two balls are in the second quadrant Q2, the number “2” was “rolled”, etc.
By increasing the number of balls and/or by the use of balls, which are different from each other, the number of possibilities may be significantly increased. Calculations have shown that for example more than 400,000 options can easily be achieved with a suitably populated random generator 10 of FIG. 2, if one uses n=9 balls, which all differ from each other (by color, finish, marking, labelling, or the like).
It is an advantage of the invention that the random generator 10 operates mechanically and is therefore non-deterministic. Software-based random generators, however, are always deterministic. Therefore, one uses in the context of software-based random number generators also mechanical processes to make the random numbers determined by software non-deterministic. The present invention allows a combination, if the random generator 10 is equipped with sensors, in order to automatically detect the position of the balls or the pattern formed by scanning the balls. The sampled or detected result can be transferred to a computer, there to affect the random generation, or to serve as a random result. The reading of the position of the balls or of the pattern is preferably carried out opto-electrically or magneto-electrically in connection with the respective embodiments. Also possible is the use of a CCD chip (Charge-coupled device), in order to “read” the position of the balls or the pattern and passed it on to a computer.
Embodiments of the invention also are possible in which the random generator 10 is a micro-system (that is a miniaturized device), the components of which have smallest dimensions (in the micron range), and which interact as a system as described herein. If such a system is equipped with small micro electro-optical sensors or a CCD chip, one gets a micro-system, which can be referred to as micro-opto-electro-mechanical system (MEMS).
Such a microsystem can for example serve as a hardware random generator that generates real, non-deterministic random numbers. Preferably, such micro-system is carried out in silicon technology.
Preferably, such micro-systems of the invention are integrated into the appropriate hardware (e.g., in a network router or switch). Moving the random generator 10 configured as a microsystem may then be done manually or through the use of an excitation body (vibration member) and actuator (for example, piezo-based).
Random generators 10 implemented as microsystems with integrated excitation body (vibration member) or actuator (e.g. piezo-based) are completely self-sufficient, i.e. they do not need any manual handling.
Computers, smart phones, tablet computers, communications hardware, and other equipment can be fitted in the future with random generators 10 of the invention implemented as microsystems.
