Abstract
A play piece may be positioned in three dimensions without actually contacting a play piece. A three dimensional structure may be include with a grid of electromagnetic actuators. By selectively controlling the current through such actuators, the position of the play piece, having a permanent magnet, may be adjusted. In addition, the current induced by the play piece may be utilized to determine the location of the play piece.
Description
- This invention relates generally to devices that are able to position other devices without contacting those devices.
- In a number of toy applications, it is desirable to move a game piece or toy element in two or more dimensions. For example, in a number of play scenarios involving board games, a play piece may be moved by the user. In addition, play pieces may be manipulated by the user in various toy scenarios.
- Generally, toy manipulation techniques require the child to actually grab the toy and to position the toy where desired. This limits the realism that is possible and thereby reduces the value of the toy.
- Children have been fascinated by magicians who use so-called levitation techniques to cause objects to rise into the air, apparently without physical contact. Usually, these techniques involve using thin wires that are not visible to the user.
- Nonetheless, levitation acts create a sense of wonderment and are entertaining for children of a variety of ages. Therefore, there would be a considerable interest in a toy which actually implements a levitation trick.
- In particular, a toy that enables the levitation of play pieces would be of considerable potential play value.
- FIG. 1 is a perspective view of one embodiment of the present invention;
- FIG. 2 is a cross-sectional view taken generally along the line2-2 in FIG. 1;
- FIG. 3 is a block depiction of the embodiment shown in FIG. 2;
- FIG. 4 is a depiction of a walls12 in accordance with one embodiment of the present invention;
- FIG. 5 is a flow chart for software in accordance with one embodiment of the present invention; and
- FIG. 6 is a flow chart for software in accordance with another embodiment of the invention.
- Referring to FIG. 1, a three dimensional, partial enclosure or three
dimensional structure 10 may facilitate the contact-free manipulation of the position of atoy play piece 11. In the illustrated embodiment, theplay piece 11 is a toy submarine submerged in a liquid L contained by thestructure 10. In one embodiment, theenclosure 10 includes a plurality of peripheral walls 12 and abottom surface 15. The top surface of thestructure 10 may be open for access and viewing in one embodiment. - As shown in FIG. 2, the
play piece 11 may include apermanent magnet 13. As will be described in more detail, theplay piece 11 may be eletromagnetically positionable due to the influence of electromagnets in the walls 12 on thepermanent magnet 13. In addition, in some embodiments, theplay piece 11 may include one or more air pockets to make theplay piece 11 neutrally buoyant. - While the
play piece 11 is illustrated as being neutrally buoyant in a liquid L, in other embodiments, theplay piece 11 may be suspended in air. For example, theplay piece 11 may include buoyancy enhancing material such as helium. Alternatives, theplay piece 11 may be sufficiently light to be suspended by the electromagnetic fields described hereinafter. As still another embodiment, theplay piece 11 may be uplifted by upwardly directed air flows. - Referring to FIG. 4, each wall12, such as the
wall 12 d, includes a plurality ofelectromagnets 22. Eachelectromagnet 22 is capable of generating an electromagnetic field that attracts or repels thepermanent magnet 13 in theplay piece 11. - In some embodiments, the
electromagnets 22 may be molded directly into the wall 12. In still another embodiment, theelectromagnets 22 may be incorporated into a film which is attached on the inside surface of the wall 12. A variety of other techniques may be utilized to associate theelectromagnets 22 with the walls 12. - A matrix of
electromagnets 22 in eachwall 12 a to 12 d may allow relatively fine control over the attractive or repulsive forces applied electromagnetically to theplay piece 11. That is, current may be selectively applied to one or more of theelectromagnets 22 to create the desired force that enables positioning of thetoy play piece 11 relative to any set ofelectromagnets 22. Moreover, ifelectromagnets 22 are provided in each of thesurface 15 and walls 12, theplay piece 11 may be positioned relative to any of those surfaces as desired, in one embodiment of the present invention. - Referring to FIG. 3, in accordance with one embodiment of the present invention,
arrays 18 ofelectromagnets 22 may be provided in each of thewalls bottom surface 15 in one embodiment. Each of thearrays 18 may be controlled by acontroller 24. Thecontroller 24 may receive user inputs from aninput device 16 and may display information on adisplay 52. Thecontroller 24 may be associated with amemory 30 that stores information including thesoftware programs - In accordance with one embodiment of the present invention, the
software program 32 may enable theplay piece 11 to be precisely positioned in response to user input commands received through theinput device 16. In another embodiment of the present invention, the precise position of aplay piece 11 may be determined by thesoftware 42. Thesoftware 42 may enable the position of the device to be displayed on adisplay 52 in one embodiment. - In particular, the
controller 24 selectively couples current to any one or more of theelectromagnets 22 to develop a sufficient attractive or repulsive force to control the position of theplay piece 11. This control may be implemented automatically by software running on thecontroller 24 which determines, based on the user input, how to appropriately supply current to theelectromagnets 22 to achieve the desiredplay piece 11 positioning. - Referring to FIG. 5, the
software 32, in accordance with one embodiment of the present invention, may receive an input command from theinput device 16, as indicated inblock 34. In one embodiment of the present invention, theinput device 16 may be a touch screen display that enables the user to simply touch a displayed image of theenclosure 10 to appropriately suggest aplay piece 11 position. However, any input device may be used as theinput device 16. - The
software 32 then calculates the displacement needed to achieve the requested position, as indicated inblock 36. Next thesoftware 32 determines the appropriate electromagnet signals in order to appropriately displace theplay piece 11, as indicated inblock 38. Finally, the inductor signals may be issued, causing theplay piece 11 to move appropriately, as indicated inblock 40. - In response to a user request or otherwise, the position of the
play piece 11 may be determined by thesoftware 42 in accordance with one embodiment of the present invention. When theplay piece 11 is appropriately positioned where desired, thecontroller 24 may go into a receive mode wherein it receives induced current signals from thearrays 18, as indicated inblock 44. Those induced current signals may be indicative of the relative position of theplay piece 11 and particularly itspermanent magnet 13 relative tovarious electromagnets 22. Those current signals may then be analyzed as indicated inblock 46. - Based on the analysis of those induced current signals, a plurality of signals may be derived as indicated in
block 48. Using known characteristics of inductors, those induced current signals may be translated into acorresponding play piece 11 location in three dimensions as indicated inblock 48. Thereafter, the calculatedplay piece 11 location may be displayed on thedisplay 52 as indicated atblock 50. - By varying the flow of electricity through any given
electromagnet 22, the strength of the field induced by the electromagnet's inductor may be altered. As a result, the attractive or repulsive applied force and, thus the position of theplay piece 11 in three dimensions may be controlled. - In one embodiment of the present invention, an aquarium may be implemented as the
enclosure 10. Other play scenarios may include a movie set or game pieces. - While the present invention has been described with respect to a limited number of embodiments, those skilled in the art will appreciate numerous modifications and variations therefrom. It is intended that the appended claims cover all such modifications and variations as fall within the true spirit and scope of this present invention.
