Description

Computerized yo-yo

Technical Field

The application discloses the number as follows: divisional application of CN107073338A, filing date: on day 13 of month 2 of 2015, application numbers are: 201580008583.5, the name is: the invention discloses a computerized yo-yo, and relates to a computerized yo-yo toy. Computerized yo-yo includes devices with programmable lights, sounds and other features to provide entertainment to the yo-yo. These features are based on the motion and state of the computerized yo-yo. In addition, the computerized yo-yo includes means for controlling the motion of the computerized yo-yo, such as: an electric clutch and an electric motor.

Background

Yo-yo is one of the oldest toys. The yo-yo toy is said to originate in china, but was first recorded in greek painting approximately 500 b.c.. Modern yo-yo toys are designed in the same concept as ancient yo-yo toys, but can be made of modern materials (e.g., plastic or metal alloys), can have different shapes (e.g., butterfly-shaped yo-yo), and can also incorporate modern mechanical processes (e.g., rolling ball bearings).

Some commercially available yo-yo toys may contain electronic components in addition to mechanical parts. The prior yo-yo toy contains a battery, lights and a mechanical device that turns the lights on and off to increase entertainment. This concept, as well as some more advanced modifications (e.g., addition of audio, liquid crystal display, control and feedback, etc.) are described in U.S. patents 4,327,518, 5,145,444, 5,356,328, 5,791,966, 6,287,193, 6,634,922 and 6,695,670.

Some commercially available yo-yo toys may also include improved mechanical features that enhance the entertainment experience of playing the yo-yo toy. For example, the yo-yo presently on the market contains a centrifugal mechanical clutch that opens when the yo-yo spins very quickly, going into a long "sleep state" (the yo-yo spins quickly at the tail) and an automatic "wake state" (the yo-yo returns quickly from the "sleep" position back into the player's hands). Other advanced combinations of mechanical parts and electrical components may enhance control of yo-yo motion, also described in U.S. patent nos. 7,448,934 and 8,187,052.

Detailed Description

The computerized yo-yo of the present invention comprises advanced electrical components, mechanical parts, and electromechanical parts, with further entertainment features, thereby further enhancing the entertainment experience of playing the yo-yo toy. Although the invention has been described with respect to specific embodiments, the principles of the invention are clearly applicable beyond the scope of the specific embodiments described herein with respect to the invention. Moreover, certain details have been omitted in describing the present invention in order not to obscure the various aspects of the present invention. The details omitted are within the knowledge of a person of ordinary skill in the art.

The drawings in the present application and their accompanying detailed description are directed to merely exemplary embodiments of the invention. In the interest of brevity, other embodiments which use the principles of the present invention are not specifically described in the present application and are not specifically illustrated by the present drawings. It should be noted that, unless otherwise indicated, similar or corresponding elements of the drawings may be referred to with similar or corresponding reference numerals.

The invention may also be used in whole or in part with other similar rotating toys, such as: a flying saucer, top (or spinning top), four-sided top, or other rotating toy or device.

The purpose of any game is to provide entertainment to the game player. Thus, games with more features and more options are more entertaining, namely: a better entertainment experience may be provided. Figure 1 shows a schematic view of a simple conventional yo-yo. The conventional yo-yo body 100 may be made of conventional materials such as wood or ceramics, or modern materials such as metal alloys, plastics, or other materials. Yo-yo body 100 is formed of two semi-circular shapes, which may be flat, spherical, conical, or any other suitable circular shape. The yo-yo shaft 130 connects the two halves of the yo-yo body 100 so that the yo-yo appears to be symmetrical and radial for the spinning toy. One end of the string 110 is attached to the yo-yo shaft 130 and the other end is attached to the retaining ring 120. The positioning ring 120 may be made of a suitable material or may be a simple ring at the end of the cord 110. The string 110 attached to the yo-yo shaft 130 may be tied tightly at one end or may form a loose loop around the yo-yo shaft 130.

If one end of the string 110 is tightly tied around the yo-yo spindle 130, the yo-yo play is fairly straightforward. First, the player winds the string 110 in a narrow recess between the two halves of the yo-yo body 100 (the terms "wind" or "rewind" in this specification are used to describe the rolling of the string 110 about the yo-yo shaft 130, or, as will be described later, other components of the yo-yo, forming the string 110 into multiple overlapping loops as required at the start of play). The player then throws or throws the yo-yo ball 100 distally or downwardly while gripping the retainer ring 120. The tension induced by the stretched string 110 causes the yo-yo body 100 to spin, and when the string 110 is fully stretched, it begins to recoil itself about the yo-yo shaft 130, and the yo-yo body 100 begins to roll upward back into the hands of the player holding the yo-yo. The player can also use the hand movement to increase the inertia of the yo-yo, so that the yo-yo can do repeated up-and-down movement. Such yo-yo games provide a limited entertainment experience for the player.

On the other hand, if one end of the string 110 forms a loose loop around the yo-yo shaft 130, the yo-yo game is more enjoyable and therefore provides a better play experience. Similar to a simple game, a player will wind the string 110 and throw or throw the yo-yo body 100 away or downward. Once strand 110 is fully extended, a loose loop at one end of strand 110 around yo-yo shaft 130 allows yo-yo ball 100 to continue spinning while strand 110 remains fully extended. This state of the yo-yo is termed the "sleep" state, and can be said to be the yo-yo "sleeping", and so on. When the yo-yo is "asleep," the player can perform various yo-yo "festoons," which is a yo-yo motion sequence that demonstrates the player's skill and flexibility. These skills and flexibility are based on the fact that: the spinning yo-yo can remain in position as long as it spins fast enough (i.e., the angular momentum of the yo-yo remains constant, similar to a gyroscope). After the entire set of movements is completed, the user can quickly and forcefully swing his or her arms, hands or fingers, causing one end of the string 110 to tighten around the loose loop of the yo-yo spindle 130 due to friction, causing the string 110 to rewind around the yo-yo spindle 130, so that the yo-yo body 100 can begin to roll upward back into the user's hands. This yo-yo skill is called "wake-up" yo-yo and can be said to be yo-yo "awake", "waking up", and so on.

It is clear that in the "sleep" state, the yo-yo loses some spin speed due to the friction between the loose loops at one end of the string 110 and the yo-yo shaft 130 and the friction between the string 110 and the inner walls of the two hemispheres of the yo-yo body 100. Modern yo-yo toys may utilize ball bearings to reduce spin losses in the "sleep" state. Figure 2 is a side schematic view of a yo-yo with ball bearings. Similar to a conventional yo-yo, the yo-yo is also made of yo-yo body 100 connected to yo-yo shaft 130. However, the yo-yo ball bearings 210 are placed around the yo-yo ball axles 130. Ball bearing 210 is comprised of an inner wheel attached to yo-yo shaft 130, an outer shell to which string 110 is tightly attached, and a ball or cylinder that can rotate between the inner wheel and the outer shell to reduce the relative rotational friction between the inner wheel and the outer shell. Other devices may be considered ball bearings even without a ball or cylinder, provided that such devices serve the same purpose, rotate smoothly, and the friction between the inner and outer parts is minimized. Such other devices may utilize teflon, silicone or other polymer coatings or other methods to reduce friction between the internal and external parts of the device, allowing smooth rotation with minimal friction between the two parts. Of course, ball bearing 210 may be formed such that yo-yo shaft 130 forms the inner ring of ball bearing 210. The yo-yo with ball bearings rotates in a similar manner to a conventional yo-yo with a loose loop around the yo-yo shaft 130 at one end of the string 110. However, since the ball bearings almost eliminate the friction between the string 110 and the yo-yo spindle 130, the yo-yo with the ball bearings loses much slower spin than a traditional yo-yo, and the player can perform more yo-yo play, or simply enjoy a longer "sleep" state time. Therefore, the yo-yo with the ball bearings can improve the entertainment experience compared with the traditional yo-yo.

While the yo-yo with ball bearings maintains its spin for longer than a conventional yo-yo, it is generally more difficult to "wake up" a yo-yo with ball bearings than to "wake up" a conventional yo-yo. Quick flicking of the hand is required to ensure that the friction of the ball bearing is sufficiently increased to cause the string 110 to form a small new loop and/or knot and that the new loop and/or knot of the string 110 creates enough initial friction with one of the inner walls of the yo-yo body 100 that the string 110 begins to rewind around the yo-yo shaft 130, thereby causing the yo-yo to roll upward. (the ball bearing yo-yo of FIG. 2 allows the inner wall surface of yo-yo body 100 near yo-yo shaft 130 to be roughened to help create the initial friction to "wake up" the yo-yo.) this presents an interesting dilemma in the design of a ball bearing yo-yo. In one aspect, the wider gap between the two halves of the yo-yo body 100 reduces the friction between the string 110 and the yo-yo body 100 in the "sleep" state. On the other hand, too wide a gap makes "waking up" the yo-yo more difficult because of the more dexterous hand movements required to create sufficient initial friction between the string 110 and the inner walls of the yo-yo body 100. Some embodiments of the present invention alleviate this dilemma.

Figure 3 is a schematic view of the apparatus included in a computerized yo-yo (300). The physical structure of the computerized yo-yo (300) is similar to the yo-yo with ball bearings described in figure 2, but the computerized yo-yo (300) contains additional devices as described herein. The present invention may be implemented by a subset of the operations of the devices described in fig. 3, or by all of the devices described in fig. 3.

At the heart of computerized yo-yo (300) is a computing and control device (305). The computing and control device 305 is configured to receive measurements indicative of the motion of the computerized yo-yo 300 from the sensors, the accelerometer device 315 and the tension meter device 350, simultaneously or separately. The computing and control device 305 is configured to generate control signals to control the operation of the components of the computerized yo-yo 300 that enhance the entertainment experience, such as: a light-emitting display device 320, an audio playback device 325, an auxiliary device 330, an electric clutch device 335, and an electric motor device 340 ("entertainment element"). The computing and control device 305 may also receive feedback information from each entertainment element regarding its status and function. The calculation and control device 305 may also be connected to a communication device 345, and the communication device 345 may both receive data of the calculation and control device 305 from an external device and transmit data of the calculation and control device 305 to the external device. (the communication device 345 and the tension meter device 350 may also transmit and receive data to and from each other). The external device may be a hand-held device such as a smartphone or tablet computer connected to the communication device 345 via a wireless link such as WiFi (IEEE 802.11 protocol), bluetooth protocol, or other communication protocol that may provide a communication link between the external device of the computerized yo-yo 300 and the communication device 345. The computing and control device 305 and the communication device 345 may be implemented separately or using the same solid state electronic microchip (e.g., Texas instruments CC2541 SimpleLink Bluetooth Intelligence and proprietary wireless MCU).

The battery 310 provides power to the other devices of the computerized yo-yo 300 and is connected to the other devices included in one embodiment of the computerized yo-yo 300. The connection of the batteries is very simple and is therefore not explicitly shown in fig. 3. There may be more than one battery used by the computerized yo-yo 300. The battery 310 may be charged by a wired or wireless power source, or may be charged by the electric motor device 340 as a generator.

Accelerometer device 315 measures acceleration values of computerized yo-yo 300 and sends the measured acceleration values to computing and control device 305. The acceleration value of the computerized yo-yo (300) is a measure of the acceleration time of a portion or portions of the computerized yo-yo (300). The acceleration value may indicate an acceleration, a derivative of an acceleration, or other function or value used to determine an acceleration. Accelerometer technology is a well known technology. Accelerometer devices are widely used in the market place, and custom made accelerometer devices are also common in the industry, particularly those made of piezoceramic materials. Accelerometer device 315 may be made of a piezo-electric ceramic material, either compressive or flexural, but may also be made of mechanical, electrical, piezoelectric, piezoresistive, solid state, or other techniques suitable for producing accelerometer device 315.

Figure 4 is a schematic illustration (not to scale in figure 4) of an alternative configuration of accelerometers of the accelerometer device 315 of the computerized yo-yo 300. The accelerometer device 315 may be placed in the center of the yo-yo body 100. The four accelerometer components of FIG. 4 are labeled 410A, 410B, 410C, and 410D, but the accelerometer components may take any number. Each accelerometer assembly 410A-410D may be an accelerometer device that includes 3 different accelerometer units (one for each spatial dimension), or may be a single accelerometer unit that measures acceleration in one direction (radial in fig. 4). If the yo-yo body 100 spins around the yo-yo axis 130 and rolls up and down, but does not move sideways, the configuration described in figure 4 is sufficient to measure the acceleration values of these motions. However, since the yo-yo may "shake", uncontrolled, it may also be advantageous to measure acceleration perpendicular to the main spin plane of the yo-yo. If the accelerometer assemblies 410A-410D of FIG. 4 are each a single accelerometer unit capable of measuring acceleration in only one direction (radial), then an additional accelerometer assembly (not shown in FIG. 4) is used to measure acceleration perpendicular to the main spin plane of the yo-yo. The additional accelerometer components may have different characteristics than accelerometer components 410A-410D because vertical acceleration values are expected to be much smaller than radial acceleration values.

The acceleration values are dependent on the motion of playing the computerized yo-yo 300, and the purpose of measuring the acceleration values is to extract information about the motion of the computerized yo-yo 300. The extracted information may be used to control the entertainment element and may also be sent to an external device for further analysis, storage, or display. The athletic information may be the acceleration of any portion of the computerized yo-yo (300), the derivative of the acceleration of any portion of the computerized yo-yo (300), the center position of the computerized yo-yo (300), the center velocity of the computerized yo-yo (300), the spin rate of the computerized yo-yo (300), or other information that may be used to control entertainment elements or may be used by an external device for further analysis, storage, or display.

The measured acceleration values may be used to extract information about the state of the computerized yo-yo 300, where the state refers to the activity of the computerized yo-yo 300 in a certain position, moving in a certain motion, or in a certain play configuration, as will become apparent from the following examples. The example is about a yo-yo game with ball bearings comprising the following seven state sequences:

state 1: holding yo-yo

State 2: ball throwing and rolling ball

State 3: downward motion of yo-yo

And 4: stopping the downward movement of the end of the rope

And state 5: sleep state

And 6: quick-acting yo-yo

And state 7: upward movement of yo-yo

FIG. 5 illustrates an example acceleration curve representing acceleration values versus time for one of the accelerometer assemblies 410A-410D in the game sequence described above. The x-axis of FIG. 5 is time (in ms) and the y-axis is acceleration values (in m/s).

In state 1 (fig. 5 labeled S1), the acceleration values are very small (unless the yo-yo is hit on some other object, firmly gripped in the hand, dropped and hit the floor, etc., there is a high probability of a high acceleration peak occurring in a short time). State 1 may be detected with a low-level average of the median filtered acceleration value.

In State 2 (labeled S2 in FIG. 5), the player uses vigorous arm, hand, or wrist movements to pitch the yo-yo, thereby accelerating the yo-yo to move further or downward. The acceleration at this step is characterized by a smooth curve, where the magnitude of the curve and its slowly varying slope (derivative of the acceleration) depend on the strength and skill of the player. State 2 can be detected with a significant increase in the average value of the acceleration values, without a peak acceleration value.

State 3 begins at the end of the arm, hand or wrist throwing motion, and the yo-yo is released from the player's hands and begins to roll rapidly downward. In this state (labeled as S3 in fig. 5), the acceleration values measured by the radially positioned accelerometer assembly (similar to that described in fig. 4) can reach even higher values. Gravity causes the spin to increase as the yo-yo moves downward. The spin of the yo-yo at segment S3 is indicated by half-cycle perturbations caused by earth gravitational pull that affects the accelerometer assembly to rotate in opposite directions for each half-cycle. The increase in rotational speed is represented by an increase in the magnitude of the acceleration value and a decrease in the half-cycle perturbation time interval. State 3 can be detected by a significant instantaneous increase in the derivative of the acceleration curve after a half-cycle disturbance as the average amplitude increases and the frequency increases, which can be detected by identifying the lowest and highest points on the acceleration curve.

State 4 occurs when the string is fully extended and its tension stops the yo-yo from downward motion. At this step (marked by S4 in FIG. 5), the downward motion of the yo-yo is suddenly interrupted, causing an extremely strong peak in the acceleration curve. The actual value of the acceleration peak of the segment S4 depends on several factors, including the initial throwing power, the yo-yo weight, and the elasticity of the string. State 4 can be detected with the maximum peak of the acceleration curve.

State 5 is the "sleep" state and fig. 5 is represented by the S5 segment. Similar to the latter part of state 3, the acceleration curve of state 5 exhibits half-cycle perturbations due to earth's gravitational pull. The rotation speed is slowly reduced due to friction, represented by a slow decrease in the amplitude of the acceleration curve and an increase in the half-cycle perturbation time interval. The length of the segment S5 is likely to be much longer than that described in FIG. 5, and the yo-yo player can perform other yo-yo actions (yo-yo solicitations) starting from the yo-yo' S "sleep" state. State 5 may be detected by a smooth average of the acceleration curve and by identifying the lowest and highest points on the acceleration curve.

State 6 (FIG. 5, labeled S6) occurs when the player decides to return the yo-yo back into the hand and quickly flick the arm, hand, or fingers downward and upward to "wake up" the yo-yo. The rapid downward movement can release the rope and the rapid upward movement can tighten the rope ring near the inner wall of the yo-yo body and/or form a knot, so that the rope is rewound around the shaft, and the yo-yo moves upward. Initial downward whipping motion causes the difference between the lowest and highest points of acceleration to diminish rapidly because the yo-yo will be quickly in a near free-fall condition. Subsequently, the acceleration profile peaks sharply due to the abrupt change in yo-yo action. State 6 can be detected by a rapid decrease in the difference between the lowest and highest points of the acceleration curve, after which the acceleration curve will have a larger peak.

State 7 (marked by S7 in fig. 5) refers to the yo-yo rolling up. The acceleration curves exhibit the same half-cycle perturbations as state 3 and state 5. State 7 may be detected with a significantly smaller variance in acceleration values compared to state 6.

FIG. 5 demonstrates that information about yo-yo motion and state can be determined by acceleration value analysis. The analysis requires extraction of parameters such as acceleration derivatives, positions and values of the highest and lowest points, and parameter change positions. These parameters may be used to extract (i.e., calculate) the yo-yo center position, the yo-yo center speed, the yo-yo spin speed, or other parameters that control the yo-yo or provide information about its position, motion, or state. FIG. 5 provides an example of an acceleration profile for one of the accelerometer assemblies 410A-410D, but may be used in combination with acceleration values of different accelerometer assemblies to analyze the position, motion, or state of the yo-yo. For example, averaging the acceleration values of all accelerometer assemblies 410A-410D may provide information about the motion of the yo-yo center. The parameters are referred to as "state parameters" and can be extracted by the computing and control device 305 of the other device controlling the computerized yo-yo 300, or can be transmitted to an external device by the communication device 345. These parameters may initially be any parameters extracted from the acceleration values (including but not limited to the acceleration values themselves).

As long as the entertainment purpose can be achieved, the computerized yo-yo (300) can also use a low-precision accelerometer with lower price. Such low precision accelerometers are sufficient to extract state parameters with sufficient accuracy even though they are unable to measure acceleration values with the accuracy required to consistently determine the exact position and exact movement of computerized yo-yo 300.

The use of the tension meter means 350 helps to improve the detection of yo-yo motion and conditions by measuring the tension at the end of the rope 110 near the tightening band 120 and providing a tension value to the calculating and control means 305. The tensiometer device 350 may consist of a single piezo-ceramic element, but may also consist of mechanical, electrical, piezo-resistive, solid state or other techniques required to produce the tensiometer 350. Power and data transfer may be accomplished through the cord 110, or the tension meter device 350 may include a power-supplied miniature battery, or may include an auxiliary communication device to communicate with the yo-yo communication device 345. Notably, the tensiometer means 350 exhibits a significant increase in tension values at the beginning of states 3, 4 and 6, which may assist in detecting initial instances of these states. Thus, the state parameter may also comprise the tension value and any parameter extracted from the tension value.

Calculation and control device 305 may use the acceleration value of accelerometer device 315 (or the tension value of tension meter device 350, both used together or separately), the extracted state parameters, and the received setup parameters (discussed later) to generate control signals to operate the entertainment elements of computerized yo-yo 300, such as: a light-emitting display device 320, an audio playing device 325, an auxiliary device 330, an electric clutch device 335, and an electric motor device 340.

The lighted display device 320 may include any number of light emitting elements, such as, but not limited to, LEDs or lasers, and may be placed anywhere within or on the yo-yo body 100. The light emitting display device 320 may also contain wires, electronic switches, dimmers, power amplifiers or other components and any necessary connections between these components that may be used to operate the light emitting components. The components of the illuminated display 320 may be located anywhere within or on the yo-yo body 100. The light emitting display device 320 may also be implemented as a detachable device, as discussed later. Some examples of operating the lighted display device 320 include, but are not limited to, low or soft lighting when holding the computerized yo-yo 300 (state 1), flashing lights when throwing the computerized yo-yo 300 (state 2-state 3), when reaching the end of the string 110 (state 4), or "wake-up" (state 6). In other examples, depending on the configuration of the light emitting elements and the motion and state of the computerized yo-yo (300), lighting synchronized with the yo-yo motion can provide entertainment effects, such as: the lights flash, while the computerized yo-yo (300) is spinning, but appears to be stationary, or the displayed graphics or characters appear to be stationary, or can move in an entertaining fashion. In addition, the light display may be synchronized with the beat and/or intensity of the audio played by the audio playback device 325 when synchronized with the audio playback device 325. The light pattern may be fixed, and may also be varied, downloaded or programmed, as discussed later.

The audio playback device 325 may comprise an electrical, electromechanical, electromagnetic, or piezoelectric component operable to generate audible sound. These components may be speakers, memory components for storing pre-stored or downloadable audio files or audio formats (e.g., MIDI), digital-to-analog converters, power amplifiers, or other components, as well as any necessary connections between these components. The components of the audio playback device 325 may be located anywhere in or on the yo-yo body 100. The audio playback device 325 may also be implemented as a detachable device, as discussed below. While the player is playing the computerized yo-yo (300), the audio playback device (325) can be used to play entertainment audio, such as: music, sound effects, human voice, animal voice, or other entertaining, stimulating audio and sounds. Some examples of operating the audio playback device 325 include, but are not limited to, playing light music while holding the computerized yo-yo 300 (state 1), generating a loud sound when throwing the computerized yo-yo 300 (state 2-state 3), reaching the end of the string 110 (state 4), or "waking up" (state 6). In another example, audio may be played through a beat corresponding to the spin rate of the computerized yo-yo 300. Entertainment audio information (e.g., recorded audio (music, voice, noise, etc.)), MIDI format data, or other audio data may be fixed and pre-stored in the memory component, or the audio information may be changed, downloaded, or programmed as discussed later.

Stationary entertainment elements may be created for the computerized yo-yo (300), such as: the illuminated display device 320 on one side of the computerized yo-yo 300 and the audio playback device 325 on the other side of the computerized yo-yo 300, even devices that combine the illuminated display device 320 and the audio playback device 325 together on each side of the computerized yo-yo 300, or other arrangements or configurations of such entertainment elements. However, if these entertainment components (and the accessory 330 described in more detail below) are removable, allowing different types of removable implements to be attached to the computerized yo-yo (300) and, if desired, replaced with other removable devices, then the entertainment experience can be enhanced.

Figures 6A, 6B and 6C illustrate that it is possible to implement a snap-lock base 605 with a removable device that can be formed into the yo-yo body 100, and in particular, into one or both of the two halves of the yo-yo body 100. The locking base 605 may be formed by the recessed space of the yo-yo body 100 and the removable device may be inserted into the locking base 605 and locked by the

locks

610A, 610B, 610C and 610D. The latch base 605 may also include a connecting pad 615 and a pad ring 620. The connecting pads 615 of the snap-lock base 605 may be made of copper or other metal strip that provides electrical signals and power from the yo-yo body 100 to the detachable means of the snap-lock base 605. The gasket ring 620 may be made of rubber or silicone and may provide cushioning and resistance. One of the latches, e.g., latch 610A, may be configured to move, and the urging spring 630 may urge the latch 610A to move toward the center of the latch base 605. The removable device can be inserted into the latch base 605 under the

latches

610B, 610C and 610D and properly and tightly latched by the latch 610A due to the urging of the urging spring 630. It will be apparent that other configurations of clasping, latching or connecting the detachable device are possible. By way of example (but not limitation), the recessed space of the latch base 605 may be square, rectangular, hexagonal, or other shape. In addition, the removable device can be inserted into the slot of the yo-yo body 100 to function as an alternative to the snap-in base 605, rather than utilizing the recessed space of the snap-in base 605. In another arrangement, the recessed space can be eliminated, allowing the removable device to snap onto the outer surface of one or both of the two halves of the yo-yo body 100. Pins, holes, recesses, screws or other mechanical means for suitably securing the removable device may be used in place of any number of latches. Any number of latches may be provided with the jostling spring 630 and the jostling spring 630 may be replaced with other mechanisms that facilitate locking of the removable device. The connection pads 615 of the latch base 605 may have any shape, may be made of any material, and may provide electrical signal connections and power supplies to the detachable device, such as, but not limited to, metal pins that may be embedded in metal eyelets for electrical connection. In addition, there are several attachment pads that may be used in place of the single attachment pad 615. The pad ring 620 may have any shape and may be made of any material, including non-annular bodies such as pad surfaces, so long as it provides cushioning and resistance. The snap-lock base 605 does not require one or any of the features described in fig. 6A, 6B and 6C to be implemented, so long as the snap-lock base 605 is able to snap and connect the removable device to the yo-yo body 100.

Fig. 7 shows a first possible embodiment of the luminous display device 320 implemented as a detachable device in the form of a circular disk. The detachable device attachment pad 710 is located on the underside of the detachable device and can be electrically connected to the attachment pad 615 of the latch base 605. The two pads should complement each other to provide electrical connection. Any number of light emitting assemblies 720 (such as, but not limited to, LEDs) may be located on the upper side of the removable device in a configuration desired for the location, size, color, or other attributes of the light emitting assemblies 720. Other support components (such as, but not limited to, memory, switches, dimmers, impedance transformers, power amplifiers or other components necessary to operate the lighted display device 320 and the lighting assembly 720) may be placed in or on the body of the removable device, or in or on the yo-yo body.

Fig. 8 shows a second possible embodiment of the illuminated display device 320 implemented as a detachable device in the form of a circular disk. Any number of lasers (e.g., including laser 810) may be located on the upper side of the detachable device. The following discussion of laser 810 applies to any other laser of the present embodiment. Laser 810 is attached to the upper side of the detachable device by a bracket 820, which may be located, attached or glued above piezoelectric driver 830. Thus, in addition to turning laser light 810 on or off, the beam direction of laser light 810 may be directed at a range of angles by applying or not applying an electrical signal to piezoelectric driver 830. Piezoelectric driver 830 may be replaced with any mechanical device, mechanical technique, electromechanical technique, electromagnetic technique, or other technique that may be used to direct the beam direction of laser 810 at a range of angles. Further, laser 810 may be located on or in a removable device, and the directing of the beam of laser 810 may be accomplished by moving one or more mirrors instead of moving laser 810. Other support elements (such as, but not limited to, a memory, switches, dimmer, impedance transformer, power amplifier or other elements necessary to operate the light emitting display device 320, laser 810 and piezo driver 830) may be located within or on the body of the removable device, or within or on the yo-yo body 100. A second possible embodiment of the light emitting display device 320 comprises the implementation of a detachable device attachment pad 710 (not shown in fig. 8).

Fig. 9 shows a possible embodiment in which the audio playback device 325 is implemented as a removable device in the form of a circular disk. The implementation of the audio playback device 325 requires a membrane 910 and a mechanical device (not shown in fig. 9) that can move the membrane 910 according to an electrical signal. The audio playback device 325 may utilize a piezoelectric mechanism to move the membrane 910, but other mechanisms (such as, but not limited to, electromagnetic or capacitive mechanisms) may also be utilized. Other support elements (such as, but not limited to, memory, switches, dimmers, impedance transformers, power amplifiers or other elements necessary to operate the audio playback device 325 and membrane 910) may be located in or on the body of the removable device, or in or on the yo-yo body 100. Such possible embodiments of the audio playback device 325 include implementations of a removable device attachment pad 710 (not shown in fig. 9).

The detachable device that is latched to the latch base device is used for the light emitting display device 320 or the audio playing device 325, which has various advantages, such as: the same computerized yo-yo (300) with different new types of detachable devices can be used, and the performance and price of the detachable devices can be well traded. However, the locking base 605 can be used to lock any type of detachable device (we refer to as the secondary device 330). The accessory 330 may be a disposable or semi-disposable detachable device that provides an added value of entertainment to the computerized yo-yo 300. Fig. 10 is a schematic view of a possible embodiment of the auxiliary device 330 implemented as a detachable device in the form of a circular disk. Several entertainment payloads 1010 are distributed on the upper side of the detachable device. Entertainment payload 1010 may be a miniature pyrotechnic payload, a colored smoke payload, a colored gunpowder payload, or a fragrance payload. The entertainment payload 1010 may also be a mini-bin containing playful mini-offers (e.g., candy or accessories) or other payloads that provide an entertainment experience for the players of the computerized yo-yo 300. Entertainment payload 1010 may utilize pyrotechnic or other activation mechanisms to ignite fireworks, process smoke, gunpowder, or scents, unlock mini-bins, or activate other entertainment features of entertainment payload 1010. The entertainment payload 1010 may be structurally distributed on the upper side of the detachable device as described in fig. 10, or may be structurally distributed on or in the detachable device in any pattern and form. Other support components necessary to operate the accessory 330 and entertainment payload 1010 may be located on or in the body of the removable device, or on or in the yo-yo body 100. Such a possible embodiment of the auxiliary device 330 comprises the realization of a detachable device connection pad 710 (not shown in fig. 10).

It is apparent that many different types of detachable devices can be designed and latched to the latch base 605 for the purpose of enhancing the entertainment experience. The type of detachable device may be any embodiment of the lighted display device 320, any embodiment of the audio playback device 325, or any embodiment of the auxiliary device 330. Since different types of detachable devices may be latched to the latch base 605, the computing and control device 305 may be configured to utilize an identification mechanism to identify the type of detachable device latched to the latch base 605. The control signal generated by the calculation and control means 305 is then adapted to the identified type of detachable device based on the identified type of detachable device to achieve the desired entertainment experience. The identification mechanism may be an analog mechanism such as: a resistor having a different resistance for each different type of detachable device, wherein the resistance can be measured using the computing and control device 305 to identify the type of detachable device that is latched to the latch base 605. The identification mechanism may also be a digital mechanism, such as: a memory component storing a different identification code for each different type of detachable device, wherein the identification code can be read by the computing and control device 305 to identify the type of detachable device latched to the latch base 605. The identification mechanism may be any mechanism by which the computing and control device 305 may identify the type of detachable device that is latched to the latch base 605.

As a first example of using an identified type of detachable device, if computing and control device 305 identifies the detachable device as being lighted display device 320 as described in FIG. 7, and if the acceleration value indicates that computerized yo-yo 300 is spinning at a speed R (e.g., measured in revolutions per second), computing and control device 305 may generate a control signal suitable for lighted display device 320 to cause lighted assembly 720 to blink at a speed FR ═ 4R (units: number of blinks/second). As a second example of using an identified type of removable device, if computing and control device 305 identifies that the removable device is audio playback device 325 as described in FIG. 9, and if the acceleration value indicates that computerized yo-yo 300 is spinning at speed R (e.g., measured in revolutions per second), computing and control device 305 may generate control signals suitable for audio playback device 325 to vibrate membrane 910 at a beat rate of BR ═ R (in units of beats/second).

The calculation and control unit 305 may generate predetermined control signals to operate the detachable unit latched to the latch base 605 according to the detected detachable unit type, namely: a particular type of removable device operates in a type of manner each time it is latched to the latch base 605. However, a particular type of detachable device may be operated in a number of different ways to achieve different entertainment experiences using a number of different sets of control signals. Furthermore, a new type of detachable device may be utilized, and the calculation and control device 305 does not have a suitable control signal for this type. It is therefore advantageous if new control signals can be downloaded to the calculation and control means 305 or generated by the calculation and control means 305 with the set parameters. The setting parameter may be a complete control signal used by the calculation and control device 305 to operate the detachable device or a parameter used by the calculation and control device 305 to generate a control signal to operate the detachable device. Accordingly, the communication device 345 may be configured to receive the setting parameters from the external device and transmit the received setting parameters to the calculation and control device 305. For example, but not limited to, the setting parameter may be a light pattern of the light emitting display device 320, audio data of the audio playback device 325, or a time and condition for activating the auxiliary device 330. In another example, the setting parameters may be: which one of several players is playing the computerized yo-yo 300?

The setting parameters may be any information received from an external device that can be used to extract status parameters, generate control signals, and operate the entertainment element. For example: if the set-up parameters indicate that player A is playing the computerized yo-yo 300 and the acceleration values indicate that the computerized yo-yo 300 is being "woken up," then the extracted state parameters and the generated control signals may control the light-emitting display device 320 to flash in red. On the other hand, if the set parameters indicate that player B is playing the computerized yo-yo 300 and the acceleration values indicate that the computerized yo-yo 300 is being "woken up", then the extracted state parameters and the generated control signals may control the light-emitting display device 320 to blink in yellow.

The external device may receive setup parameters from any source, such as: the setup parameters are downloaded from any storage medium or from the internet. Furthermore, using a dedicated program or application on the external device or any other device, the user is able to generate new interesting setting parameters for any entertainment element and any type of detachable device, which can then be sent to the computing and control device 305 and used to run any entertainment element of the computerized yo-yo 300 in a new, interesting, entertaining and exciting way.

In addition, computing and control device 305 may send information regarding yo-yo motion and status to an external device using communication device 345. The calculation and control device 305 may utilize the acceleration value of the accelerometer device 315 (or the tension value of the tension meter device 350, both used together or separately) and other information received from the entertainment element to extract and send the status parameters to the external device using the communication device 345. For example: the status parameters may include the identity of the detachable device that is latched to the latch base 605 and information regarding the status of any device or component of the computerized yo-yo 300. Thus, a status parameter is any parameter received by the calculation and control means 305, extracted by the calculation and control means 305 or generated by the calculation and control means 305. The external device may use the status parameters received from the computing and control device 305 to augment the entertainment experience, such as but not limited to: display the spin rate of the yo-yo, announce who of the two players achieved the highest throwing power according to some reasonable game requirements, or who played the computerized yo-yo 300 the longest or best, or any other use of information about the computerized yo-yo 300 motions, states, and conditions that enhance the player's entertainment experience. In addition, the external device may also use the information received from the computing and control device 305 regarding yo-yo motion, status, and conditions to calculate complex control parameters, which require more computing power than the computing and control device 305, and then send the calculated complex control parameters back to the computing and control device 305 to assist the entertainment elements in generating control signals to provide the desired entertainment experience.

The lighted display device 320, audio playback device 325, and auxiliary device 330 may create an entertainment experience for the player by responding to the computerized yo-yo 300 motions, states, and conditions. However, if the motion of the computerized yo-yo (300) can be controlled and manipulated, the entertainment experience can be further enhanced. Figure 11 is a schematic diagram of a computerized yo-yo (300) with ball bearings (210) and an electric clutch apparatus (335). Similar to the yo-yo with ball bearings described in FIG. 2, this embodiment of a computerized yo-yo (300) comprises ball bearings (210) with an inner wheel and an outer shell connected to the yo-yo shaft (130). An electric clutch assembly 335, which may be comprised of a pressure electric clutch assembly 1105, may be attached to the yo-yo body 100 at about the same distance from the yo-yo shaft 130 as the ball bearing 210 housing. The piezoelectric clutch assembly 1105 can be extended or retracted by application (or non-application) of an electrical signal. Figure 11 depicts four clutch assemblies 1105, two on each side of the yo-yo ball 100, but any number of clutch assemblies 1105 in any configuration may be used. In addition, other techniques may also be used to implement the clutch assembly 1105, such as, but not limited to: magnetic, electromagnetic or electromechanical techniques. Other elements (such as, but not limited to, wires, switches, power amplifiers, or other elements) necessary to operate the electric clutch assembly 335 and the clutch assembly 1105 are not shown in fig. 11.

The clutch assembly 1105 may be configured to contract upon application of an electrical signal (or no electrical signal applied) to remove contact or friction between the clutch assembly 1105 and the housing of the ball bearing 210 (which we call "unlock"). The clutch assembly 1105 may be further configured to extend when no electrical signal is applied (or an electrical signal is applied) thereby creating contact or friction with the ball bearing 210 housing (we refer to as "lock-up"). The contact or friction between the clutch assembly 1105 and the ball bearing 210 housing creates friction between the yo-yo body 100 and the ball bearing 210 housing in the sense that such friction affects (slows down) the relative motion between the yo-yo body 100 and the ball bearing 210 housing. Friction can be used to control the relative motion between the yo-yo body 100 and the ball bearing 210 housings, and further between the yo-yo body 100 and the string 110. For example: if the clutch assembly 1105 is unlocked, the ball bearing 210 housing is free to rotate, meaning that the motion of the computerized yo-yo 300 is identical to the motion of the yo-yo with ball bearings described in FIG. 2. In another example, when the clutch assembly 1105 is locked, the ball bearing 210 housing will rotate with the yo-yo body 100, meaning that the computerized yo-yo 300 will behave similarly to a simple yo-yo as described in figure 1 where one end of the string 110 is tightly tied around the yo-yo shaft 130. However, if the control signals generated by the calculation and control apparatus 305 can control the operation of the electrical clutch apparatus 335, the entertainment experience can be enhanced. The control signal of the electric clutch device 335 (electric clutch control signal) may be based on an acceleration value of the accelerometer device 315 (or a tension value of the tension meter device 350, both used together or separately), a state parameter extracted by the calculation and control device 305, or a setting parameter received together or separately from an external device. For example: the electric clutch control signal may control the clutch assembly 1105 to lock when the player rolls the computerized yo-yo 300, and the electric clutch control signal may control the clutch assembly 1105 to unlock completely when the string 110 is fully extended, as indicated by the acceleration value of the accelerometer device 315 (or the tension value of the tension meter device 350, both used together or alone). Thus, in another example, the electric clutch control signal may control the clutch assembly 1105 to unlock, the computerized yo-yo 300 may be in a "sleep" state, and the acceleration value of the accelerometer device 315 (or the tension value of the tension meter device 350, both used together or alone) indicates that the player is "waking up" the yo-yo, causing the computing and control device 305 to generate the electric clutch control signal to control the clutch assembly 1105 to lock, in the sense that the spin rate is increased from the "sleep" state as compared to the ball-bearing yo-yo of FIG. 2 (for a ball-bearing yo, the friction of the string 110 against the inner wall of the yo-yo body 100 is lost before the string 110 is fully extended). Thus, this makes it much faster and easier to "wake up" the computerized yo-yo (300) (for a ball-bearing yo-yo, the user needs to manipulate the string (110) to create sufficient friction between the string (110) and the inner wall of the yo-yo body (100). As another example, the computerized yo-yo (300) can be in a "sleep" state, and the clutch assembly (1105) is unlocked when the user gives a voice command (e.g., to "up" the voice)) to an external device, as compared to "waking up" the ball-bearing yo-yo of FIG. 2. The voice command may be recognized by the external device, which may send the appropriate set-up parameters to the computing and control device 305 via the communication device 345, and the computing and control device 305 may then generate an electric clutch control signal to control the clutch assembly 1105 to lock up, causing the computerized yo-yo 300 to begin rolling upward. Even if the yo-yo player does not want the electric clutch apparatus 335 to assist or interfere with the computerized yo-yo (300) during play, it is possible to simply use the electric clutch apparatus 335 to assist the rope (110) rewinding to resume play. In this example, when the string 110 is fully extended but the computerized yo-yo 300 is no longer spinning (which occurs when the player loses control of the yo-yo), the player needs to rewind the string 110 to resume play. For the yo-yo of figure 2 with ball bearings, the re-winding is not simple because the player needs to carefully manipulate the string 110 to create the initial friction and thus re-wind. For a computerized yo-yo (300) having an electric clutch device (335), the player may simply issue a voice command (e.g., "lock") to the external device. The voice command may be recognized by the external device, and the external device may send the appropriate setting parameters to the calculation and control device 305 via the communication device 345, and the calculation and control device 305 may then generate an electric clutch control signal to control the clutch assembly 1105 to lock up. Likewise, the clutch assembly 1105 may be locked upon identification of the first mode of motion. Once the clutch assembly 1105 is locked, the player can easily rewind the string 110, issue a second audible command (e.g., "unlock"), unlock the clutch assembly 1105, and then easily resume the yo-yo game. Likewise, the clutch assembly 1105 may be unlocked upon identification of the second mode of motion.

Furthermore, different levels of electrical clutch control signals are used for the clutch assembly 1105 of the electrical clutch apparatus 335, potentially resulting in different levels of friction between the clutch assembly 1105 and the ball bearing 210 housing, and thus different levels of friction between the yo-yo body 100 and the ball bearing 210 housing. Different levels of friction can be used to smoothly control the motion of the computerized yo-yo (300), such as: gradually slow the spin of the computerized yo-yo (300), or control the spin of the computerized yo-yo (300) as it moves up while "awake".

As discussed above, the width of the gap between the two halves of the yo-yo body 100 is a compromise between the need to reduce friction between the string 110 and the inner walls of the yo-yo body 100 during the "sleep" state (requiring a wider gap) and the need to "wake" the yo-yo easily (requiring a narrower gap). In the computerized yo-yo (300) depicted in fig. 12, the ball bearing (210) housing is further fitted to the inner disk (1220) to help solve this problem. Similar to FIG. 11, the computerized yo-yo (300) also includes an electric clutch apparatus (335), which may be implemented by a clutch assembly (1105). It is apparent that if the clutch assembly 1105 is unlocked, the player may throw the computerized yo-yo (300) of FIG. 12, and when the string 110 is fully extended, the computerized yo-yo (300) of FIG. 12 goes to a "sleep" state. However, it is not possible for a player to "wake up" the computerized yo-yo (300) of FIG. 12 using arm, hand, or finger movements because it is not possible to create friction between the string (110) and the inner wall of the yo-yo body (100) because the inner wall of the yo-yo body (100) is outside of the inner disks (1220). However, since the clutch assembly 1105 can be controlled by the computing and control device 305, it is possible to "wake up" the computerized yo-yo 300 of FIG. 12 by locking the clutch assembly 1105. It is noted that with the computerized yo-yo (300) of figure 12, the string (110) and the internal disks (1220) do not move relative to each other during the "sleep" state, thus eliminating the friction between the string (110) and the inner walls of the yo-yo body (100) during the "sleep" state. This means that the computerized yo-yo (300) with internal disks (1220) described in figure 12 is more efficient in the sense that it spins longer during the "sleep" state. Other elements (such as, but not limited to, wires, switches, power amplifiers, and other elements) necessary to operate the electric clutch assembly 335 and the clutch assembly 1105 are not shown in fig. 12.

When the yo-yo is in the "sleep" state and spins fast enough, the player can perform various yo-yo "festoons," which is a sequence of yo-yo movements that demonstrates the player's skill and flexibility. However, as the spin rate slows due to friction, the ability to perform yo-yo festoons is diminished or eliminated. The computerized yo-yo (300) depicted in fig. 13 includes an electric clutch device (335) and an electric motor device (340) to enhance the entertainment experience for the player. The electric motor arrangement 340 may include an electric motor 1310 mounted on the ball axle 130, similar to the ball bearings 210 of fig. 2, 11, and 12. The electric motor 1310 may have an inner member (corresponding to the inner ring of the ball bearing 210) for holding the energized coil, and a housing (corresponding to the housing of the ball bearing 210) for holding the fixed magnet. Assuming the clutch assembly 1105 has been unlocked, when no control signal is applied to the electric motor 1310, the inner member can rotate smoothly with minimal friction associated with the housing, similar to the ball bearing 210. When a control signal is applied to the electric motor 1310, a rotational force is generated between inner members and a housing of the electric motor 1310. Because the inner components of electric motor 1310 are connected to the yo-yo shaft 130, which in turn is connected to the yo-yo body 100, the rotational forces generated between the outer casing of electric motor 1310 and the yo-yo body 100 are also applied. If the yo-yo body 100 and the housing of electric motor 1310 are not initially rotating relative to each other, then rotational forces may create rotational motion between them. If the yo-yo body 100 and the housing of electric motor 1310 have moved relative to each other, then the rotational force may increase or decrease the rotational speed, or the rotational force may even reverse the direction of rotation. The cord 110 may be tied to the housing of the electric motor 1310 to function as the housing for the ball bearing 210 of fig. 2, 11, and 12.

The electric clutch device 335 and the electric motor device 340 may be controlled by the calculation and control device 305, generating electric clutch control signals and control signals (electric motor control signals) of the electric motor device 340 according to the acceleration value of the accelerometer device 315 (or the tension value of the tension meter device 350, both used together or alone), the status parameters extracted by the calculation and control device 305, or the setting parameters received together or alone from the external device. For example, after the player throws the computerized yo-yo (300) of FIG. 13, the clutch assembly 1105 can be unlocked and the electric motor arrangement 340 can be operated to increase the spin rate of the computerized yo-yo (300) when it is moved downward. In another example, when the string 110 is fully extended and the computerized yo-yo (300) of FIG. 13 is in a "sleep" state, the electric motor means (340) can be controlled and operated to maintain a constant spin rate, enabling the player to perform a long sequence of yo-yo skill elements. In additional examples, the computerized yo-yo (300) of FIG. 13 may be "woken up" by friction generated by the clutch assembly (1105) or by rotational force generated by the electric motor (1310) as the player completes the elements of skill. In a further example, as a player performs elements of the yo-yo skill, the player may issue voice commands to the external device, such as: "faster", "slower", "up", "down", which are recognized by the external device, and the external device may transmit the setting parameters to the calculation and control device 305 through the communication device 345, generate electric clutch control signals to control the electric clutch device 335, and generate electric motor control signals to control the electric motor device 340 collectively or individually, thereby controlling the motion or state of the computerized yo-yo 300 according to the issued voice commands. Other components (such as, but not limited to, electrical wires, switches, power amplifiers and other components) necessary to operate the electrical clutch assembly 335, the electric motor assembly 340, the clutch assembly 1105 and the electric motor 1310 are not shown in fig. 13.
