BACKGROUND OF THE INVENTION
Without limiting the scope of the disclosed embodiments, the background is described in connection with methods for manufacturing 3D objects and structures, more specifically 3D structural electronic, electromagnetic and electromechanical components and devices.
The recent introduction of MEMs-based accelerometers has enabled many new gaming and commercial electronics applications like enhanced features in cell phones and the Nintendo Wiimote. The introduction of the accelerometry into gaming dice has only recently been made possible by this new technology. Although a LED-lit 20 sided dice has been sold on websites like Thinkgeek, the electronics involved are basic and only involve one side (the 20) with a pressure sensor.
SUMMARY OF THE INVENTION
The disclosed embodiments can make gaming dice more visually stunning and makes the dice outcome more obvious—an important feature in a color and lighting-rich environment such as a casino. The disclosed embodiments can be manufactured using 3D printing of dielectric structures with conductive traces serving as electrical interconnects.
More specifically, the present invention provides an electronic gaming die that includes an enclosure, a flexible substrate, a number of light emitting diodes, a sensor, a processor and a battery. The enclosure has N sides where N is equal to or greater than 4. The flexible substrate folds in a manner that leaves it with N sides and fits into an interior of the enclosure, wherein each side has an inner face, an outer face and is assigned an integer from 1 to N. The light emitting diodes are disposed on the outer face of each side of the flexible substrate, wherein the number of light emitting diodes equals the integer assigned to the side of the flexible substrate. The sensor is disposed on one of the inner faces of the flexible substrate. The processor is disposed on one of the inner faces of the flexible substrate and communicably coupled to the sensor and the one or more light emitting diodes. The battery is disposed on one of the inner faces of the flexible substrate and electrically connected to the one or more light emitting diodes, the sensor and the processor.
In addition, the disclosed embodiments can provide a method for manufacturing an electronic gaming die by first fabricating a flexible substrate. The flexible substrate folds into N sides where N is equal to or greater than 4, wherein each side has an inner face, an outer face and is assigned an integer from 1 to N. A number of light emitting diodes disposed on the outer face of each side of the flexible substrate such that the number of light emitting diodes equals the integer assigned to the side of the flexible substrate. A sensor can be disposed on one of the inner faces of the flexible substrate. A processor can be disposed on one of the inner faces of the flexible substrate and communicably coupled to the sensor and the one or more light emitting diodes. A battery can be disposed on one of the inner faces of the flexible substrate and electrically connected to the one or more light emitting diodes, the sensor and the processor. Next, an enclosure having N sides is provided and the flexible substrate can be folded such that the folded flexible substrate fits into an interior of the enclosure. The folded flexible substrate can be inserted into the interior of the enclosure and the enclosure is sealed. This method can be implemented as a computer program embodied on a non-transitory computer readable medium wherein the steps are preformed using one or more code segments.

DETAILED DESCRIPTION OF THE INVENTION
While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention. For example, the present invention is described with respect to the design of a six sided gaming die that includes a microprocessor and accelerometer in order to detect a roll, measure the direction of gravity and illuminate light emitting diodes (LED) on the upward face. The present invention, however, is not limited to a six sided gaming die or the specific design examples described herein.
To facilitate the understanding of this invention, a number of terms are defined below. Terms defined herein have meanings as commonly understood by a person of ordinary skill in the areas relevant to the present invention. Terms such as “a”, “an,” and “the” are not intended to refer to only a singular entity, but include the general class of which a specific example may be used for illustration. The terminology herein is used to describe specific embodiments of the invention, but their usage does not delimit the invention, except as outlined in the claims.
Now referring to FIGS. 1A and 1B, images showing an exploded view of an electronic gaming die 100 in accordance with one embodiment of the present invention are shown. The electronic gaming die 100 includes an enclosure 102, a flexible substrate 104, light emitting diodes 106, a sensor 108, a processor 110, a battery 112 and an insert 114. The enclosure 102 (made up of main enclosure 102a and enclosure lid or cap 102b) has N sides (1021 to 102N) where N is equal to or greater than 4. In the example shown, N=6. In other embodiments of the present invention, N can equal 4, 6, 8, 10, 20 or more. The enclosure 102 can be transparent or semi-transparent. Likewise, a portion of the enclosure 102 proximate to the one or more light emitting diodes 106 can be transparent or semi-transparent, and the remainder of the enclosure 102 can be opaque.
The flexible substrate 104 folds into N sides (see also FIG. 2) and fits into an interior 116 of the enclosure 102. Each side of the flexible substrate 104 has an inner face (FIG. 1A; see also FIG. 4B) and an outer face (FIG. 1B; see also FIG. 4A). The sensor 108 (preferably a three-axis accelerometer) is disposed on one of the inner faces of the flexible substrate 104. The processor 110 is disposed on one of the inner faces of the flexible substrate 104 and is communicably coupled to the sensor 108 and the one or more light emitting diodes 106. The sensor 108 and processor 110 detect a roll, measure a direction of gravity and illuminate the light emitting diode(s) 106 on the upward face. The processor 108 can operate the light emitting diodes 106 is various modes, which can be user configurable. For example, the light emitting diodes 106 can stay lit for a specified period of time, or flash to show which side of the enclosure 102 is up when the electronic gaming die 100 stops rolling, etc. The battery 112 is disposed on one of the inner faces of the flexible substrate 104 and electrically connected to the one or more light emitting diodes 106, the sensor 108 and the processor 110. The battery 112 can be replaceable or rechargeable. For example, an interface 118 (e.g., mini USB-A, mini USB-b, micro USB-A, micro USB-b, etc.) can be electrically connected to the battery 112 and accessible from an exterior of the enclosure 102 to recharge the battery 112. Alternatively, a wireless battery recharging circuit (not shown) can be electrically connected to the battery 112 and disposed on one of the inner faces of the flexible substrate 104. Likewise, one or more photovoltaic cells (not shown) can be electrically connected to the battery 112 and disposed on or within the enclosure 102 or the flexible substrate 104.
The electronic gaming die 100 may automatically enter a sleep mode whenever one or more sleep conditions occur and remain in the sleep mode until one or more wakeup conditions occur. For example, the one or more sleep conditions may include the sensor 108 not detecting motion for a specified period of time, the sensor 108 detecting a specified sleep sequence, the electronic gaming die 100 remains stationary for a specified period of time, etc. The sleep sequence can be orienting the dice for at least two seconds with the “one” side held up, followed by the “two”, followed by the “three” and so on, or any other desired sequence. The low power mode may involve a staged power down of the electronic gaming die 100 (e.g., component-by-component starting with deactivating the light emitting diodes 106). The one or more wakeup conditions may include the sensor 108 detecting motion after the sleep mode has been entered or a specific time period thereafter, the sensor 108 detecting a specified wakeup sequence, the electronic gaming die 100 being “rolled” after the sleep mode has been entered or a specified time period thereafter, etc.
Now also referring to FIGS. 3A and 3B, exploded drawings of an enclosure 102 and insert 114 for an electronic gaming die 100 in accordance with one embodiment of the present invention are shown. The insert 114 is disposed within an interior 116 of the folded flexible substrate 104 and sized to maintain a position of the flexible substrate 104 against the interior of the enclosure 102. The enclosure 102 may include slots, channels, cavities, recesses, depressions or other inner surface features to accommodate the light emitting diodes 106 or other components disposed on the outer faces of the flexible substrate 104. For example, the enclosure lid or cap 102a in FIGS. 1A and 1B includes an opening to accommodate the interface 118.
Alternatively, the lid or cap 102a can be removable in order to change out the battery 112. Note that that one or more inscriptions can be engraved on the enclosure 102. The insert 114 can be rigid, semi-rigid, or hollow. Alternatively, the insert 114 can be eliminated and replace by: (1) an adhesive or one or more connectors that attach one or more edges of the sides of the flexible substrate 104 together to maintain a shape of the folded flexible substrate 104; (2) an expanding foam sealant disposed within an interior of the folded flexible substrate 104; or (3) any other suitable method of maintain a shape of the folded flexible substrate 104. Moreover, the insert 114 can be weighted to balance a weight of the die 100, or unbalance the die 100 to favor a specified orientation (i.e., a loaded die or “cheating” die).
Referring now to FIGS. 4A and 4B, images showing the outer faces (4201 to 420N) and inner faces (4401 to 440N), respectively, of a flexible substrate 104 for an electronic gaming die 100 in accordance with one embodiment of the present invention are shown. This embodiment and the embodiment shown in FIGS. 9A and 9B have components on both the outer faces 400 and the inner faces 420 of the flexible substrate 104. In contrast, the embodiment shown in FIGS. 10A and 10B only has components on the inner faces 420 of the flexible substrate 104, which substantially reduces the manufacturing cost.
Each side 400 of the flexible substrate 104 is assigned an integer from 1 to N (e.g., 4001 to 4006). A number of light emitting diodes 106 are disposed on the outer face 420 of each side 400 of the flexible substrate 104. The number of light emitting diodes 106 equals the integer assigned to the side 400 of the flexible substrate 104 and the corresponding side of the enclosure 102. For example and as shown in FIG. 4A, the first outer face 4201 of the first side 4001 of the flexible substrate 104 has one light emitting diode D1, the second outer face 4202 of the second side 4002 of the flexible substrate 104 has two light emitting diodes D2-D3, the third outer face 4203 of the third side 4003 of the flexible substrate 104 has three light emitting diodes D4-D6, the fourth outer face 4204 of the fourth side 4004 of the flexible substrate 104 has four light emitting diodes D7-D10, the fifth outer face 4205 of the fifth side 4005 of the flexible substrate 104 has five light emitting diodes D11-D15, and the sixth outer face 4206 of the sixth side 4006 of the flexible substrate 104 has six light emitting diodes D16-D21. Each light emitting diode D1-D21 represents a pip of the electronic gaming die 100. Alternatively, the number of light emitting diodes 106 can be greater than the number of the integer assigned to the side 400 of the flexible substrate 104 such that the number of light emitting diodes 106 are arranged to display a numeric character corresponding to the integer.
As shown in FIG. 4B, the sensor 108 and processor 110 are disposed on one of the inner faces (e.g., 4401) of the flexible substrate 104. Two leads 402 are used to connect the circuit to the battery 112 (not shown). An additional side 404 is used to mount the interface 118 (e.g., mini USB-A, mini USB-b, micro USB-A, micro USB-b, etc.) and orient the interface 118 to be accessible via the opening 406 in side 4002. As will be appreciated by those skilled in the art, the circuit includes various capacitors Cx, resistors Rx, electrical traces (conductors) and other desired components. In addition, one or more inner faces 420 or one or more outer faces 440 of the flexible substrate 104 can be coated with an ultraviolet photocurable polymer to further protect the various components and the flexible substrate 104.
The flexible substrate 104 can be fabricated using traditional flexible circuit board methodologies or fabricated using a 3D printing process wherein the electrical conductors that connect the various components are printed conductive traces that can traverse one or more folds of the flexible substrate 104. An example of such a 3D printing g system is described in U.S. patent application Ser. No. 13/343,651, which is incorporated by reference in its entirety. The three-dimensional printing device creates one or more layers of a three-dimensional substrate by depositing a substrate material in a layer-by-layer fashion. The three-dimensional printing device can be a fused deposition modeling machine, a selective laser sintering machine or another suitable device.
FIG. 5 illustrates an image of an enclosure 102 for an electronic gaming die 100 in accordance with one embodiment FIGS. 6A and 6B illustrate images of an assembled electronic gaming die 100 with a transparent enclosure 102 in accordance with another example embodiment. FIG. 7 illustrates a series of images showing the assembly process for an electronic gaming die 100 in accordance with an example embodiment. FIG. 8 illustrates an image of an electronic gaming die 100 in accordance with yet another example embodiment. As shown in FIG. 8, the electronic gaming die 100 can also be fabricated with 3D Printing technology in conjunction with micro-dispensing of conductive inks serving as electrical interconnect. 3D Printing of the structure can allow for rapid prototyping not just of the structure but also for the electronic functionality as demonstrated in FIG. 8. 3D Printing can thus allow for faster evaluation of form and function at an unprecedented level.
Referring now to FIGS. 9A and 9B, images showing the outer faces (4201 to 420N) and inner faces (4401 to 440N), respectively, of a flexible substrate 104 for an electronic gaming die 100 in accordance with another embodiment of the present invention are shown. Like FIGS. 4A and 4B, this embodiment has components on both the outer faces 400 and the inner faces 420 of the flexible substrate 104. This embodiment does, not however, show the battery leads 402 or interface 118 (e.g., mini USB-A, mini USB-b, micro USB-A, micro USB-b, etc.).
Each side 400 of the flexible substrate 104 is assigned an integer from 1 to N (e.g., 4001 to 4006). A number of light emitting diodes 106 are disposed on the outer face 420 of each side 400 of the flexible substrate 104. The number of light emitting diodes 106 equals the integer assigned to the side 400 of the flexible substrate 104 and the corresponding side of the enclosure 102. For example and as shown in FIG. 9A, the first outer face 4201 of the first side 4001 of the flexible substrate 104 has one light emitting diode D1, the second outer face 4202 of the second side 4002 of the flexible substrate 104 has two light emitting diodes D2-D3, the third outer face 4203 of the third side 4003 of the flexible substrate 104 has three light emitting diodes D4-D6, the fourth outer face 4204 of the fourth side 4004 of the flexible substrate 104 has four light emitting diodes D7-D10, the fifth outer face 4205 of the fifth side 4005 of the flexible substrate 104 has five light emitting diodes D11-D15, and the sixth outer face 4206 of the sixth side 4006 of the flexible substrate 104 has six light emitting diodes D16-D21. Each light emitting diode D1-D21 represents a pip of the electronic gaming die 100. Alternatively, the number of light emitting diodes 106 can be greater than the number of the integer assigned to the side 400 of the flexible substrate 104 such that the number of light emitting diodes 106 are arranged to display a numeric character corresponding to the integer.
As shown in FIG. 9B, the sensor 108 and processor 110 are disposed on one of the inner faces (e.g., 4401) of the flexible substrate 104. As will be appreciated by those skilled in the art, the circuit includes various capacitors Cx, resistors Rx, electrical traces (conductors) and other desired components. In addition, one or more inner faces 420 or one or more outer faces 440 of the flexible substrate 104 can be coated with an ultraviolet photocurable polymer to further protect the various components and the flexible substrate 104.
The flexible substrate 104 can be fabricated using traditional flexible circuit board methodologies or fabricated using 3D printing process wherein the electrical conductors that connect the various components are printed conductive traces that can traverse one or more folds of the flexible substrate 104. An example of such a 3D printing system is described in U.S. patent application Ser. No. 13/343,651, which is incorporated by reference in its entirety. The three-dimensional printing device creates one or more layers of a three-dimensional substrate by depositing a substrate material in a layer-by-layer fashion. The three-dimensional printing device can be a fused deposition modeling machine, a selective laser sintering machine or other suitable device.
Now referring to FIGS. 10A and 10B, images showing the outer faces (4201 to 420N) and inner faces (4401 to 440N), respectively, of a flexible substrate 104 for an electronic gaming die 100 in accordance with yet another embodiment of the present invention are shown. Unlike FIGS. 4A-B and 9A-B, this embodiment has components only on the outer faces 420 of the flexible substrate 104. This embodiment uses three additional squares or sides 1002, 1004 and 1006 to mount the various components on, such that these three sides 1002, 1004 and 1006 are bent towards the back of the completed flexible substrate 104, leaving the components effectively in the back side again. By doing this, the folded flexible substrate inserted into the inside of the cavity 116 of the dice case 102a just like the other embodiments. This embodiment greatly reduces the manufacturing price of the flexible substrate 104 (e.g., 40% or more). Some of these savings would be offset by the increased handling of the flexible substrate 104 during manufacture, increased time to build each part and increased risk of damaging it through handling.
Each side 400 of the flexible substrate 104 is assigned an integer from 1 to N (e.g., 4001 to 4006). A number of light emitting diodes 106 are disposed on the outer face 420 of each side 400 of the flexible substrate 104. The number of light emitting diodes 106 equals the integer assigned to the side 400 of the flexible substrate 104 and the corresponding side of the enclosure 102. For example and as shown in FIG. 10A, the first outer face 4201 of the first side 4001 of the flexible substrate 104 has one light emitting diode D1, the second outer face 4202 of the second side 4002 of the flexible substrate 104 has two light emitting diodes D2-D3, the third outer face 4203 of the third side 4003 of the flexible substrate 104 has three light emitting diodes D4-D6, the fourth outer face 4204 of the fourth side 4004 of the flexible substrate 104 has four light emitting diodes D7-D10, the fifth outer face 4205 of the fifth side 4005 of the flexible substrate 104 has five light emitting diodes D11-D15, and the sixth outer face 4206 of the sixth side 4006 of the flexible substrate 104 has six light emitting diodes D16-D21. Each light emitting diode D1-D21 represents a pip of the electronic gaming die 100. Alternatively, the number of light emitting diodes 106 can be greater than the number of the integer assigned to the side 400 of the flexible substrate 104 such that the number of light emitting diodes 106 are arranged to display a numeric character corresponding to the integer.
The sensor 108 is disposed the outer face (e.g., 4207) of one of the added sides 1002. The processor 110 is disposed on outer face (e.g., 4208) of the one of the added sides 1004. Additional components, such as resistors R4, R5, R7 and R8 are disposed on the outer face (e.g., 4209) of one of the added sides 1006. Two leads 402 are used to connect the circuit to the battery 112 (not shown). An additional side 404 is used to mount the interface 118 (e.g., mini USB-A, mini USB-b, micro USB-A, micro USB-b, etc.) and orient the interface 118 to be accessible via the opening 406 in side 4002. As will be appreciated by those skilled in the art, the circuit includes various capacitors Cx, resistors Rx, electrical traces (conductors) and other desired components. In addition, one or more inner faces 420 or one or more outer faces 440 of the flexible substrate 104 can be coated with an ultraviolet photocurable polymer to further protect the various components and the flexible substrate 104.
The flexible substrate 104 can be fabricated using traditional flexible circuit board methodologies or fabricated using 3D printing process wherein the electrical conductors that connect the various components are printed conductive traces that can traverse one or more folds of the flexible substrate 104. An example of such a 3D printing system is described in U.S. patent application Ser. No. 13/343,651, which is incorporated by reference in its entirety. The three-dimensional printing device creates one or more layers of a three-dimensional substrate by depositing a substrate material in a layer-by-layer fashion. The three-dimensional printing device can be a fused deposition modeling machine, a selective laser sintering machine or other suitable device.
Now referring to FIG. 11, a flow chart of operations of a method 1100 for manufacturing an electronic gaming die 100 in accordance with an example embodiment is shown. A flexible substrate can be fabricated as indicated at block 1102. The flexible substrate folds into N sides where N is equal to or greater than 4, wherein each side has an inner face, an outer face and is assigned an integer from 1 to N (e.g., equals 4, 6, 8, 10, 20, etc.). A number of light emitting diodes disposed on the outer face of each side of the flexible substrate such that the number of light emitting diodes equals the integer assigned to the side of the flexible substrate. A sensor is disposed on one of the inner faces of the flexible substrate. A processor is disposed on one of the inner faces of the flexible substrate and communicably coupled to the sensor and the one or more light emitting diodes. A battery is disposed on one of the inner faces of the flexible substrate and electrically connected to the one or more light emitting diodes, the sensor and the processor. An enclosure having N sides can be provided as shown at block 1104. The flexible substrate can be folded as depicted at block 1106 such that the folded flexible substrate fits into an interior of the enclosure. The folded flexible substrate is inserted into the interior of the enclosure as indicated at block 1108 and the enclosure is sealed as shown at block 1110. As previously described, the shape of the folded flexible substrate can be maintained by: placing an insert within an interior of the folded flexible substrate; attaching one or more edges of the sides of the flexible substrate together using an adhesive or one or more connectors; or depositing an expanding foam sealant within an interior of the folded flexible substrate. In addition, one or more inner faces or one or more outer faces of the flexible substrate can be coated with an ultraviolet photocurable polymer to further protect the various components and the flexible substrate. Moreover, this method can be implemented as a computer program embodied on a non-transitory computer readable medium wherein the steps are preformed using one or more code segments.
As previously mentioned, the flexible substrate can be fabricated using a conductive ink micro-dispensing process wherein the electrical conductors that connect the various components are printed conductive traces that can traverse one or more folds of the flexible substrate 104. An example of such a 3D printing system is described in U.S. patent application Ser. No. 13/343,651, which is incorporated by reference in its entirety. The three-dimensional printing device creates one or more layers of a three-dimensional substrate by depositing a substrate material in a layer-by-layer fashion.
