• FIG. 1 shows a schematic diagram of a simple traditional yo-yo.
• the traditional yo-yo body 100 may be made of traditional materials such as wood or ceramic, or of modern materials such as metal alloy, plastic or any other material.
• Yo-yo body 100 is made of two rounded halves, which may be flat, spherical, conic shaped or any other rounded suitable shape.
• Yo-yo axel 130 connects the two rounded halves of yo-yo body 100 and therefore the yo-yo exhibits a symmetrically-radial shape suitable for a rotating toy.
• Holding ring 120 may be made of any suitable material or may be a simple loop at the end of string 110.
• the end of string 110 that is attached to yo-yo axel 130 may be tied tightly or may form a loose loop around yo-yo axel 130.
• the player can also use hand movements to add inertia to the yo-yo and to repeat the yo-yo up and down movements. This yo-yo game provides limited entertaining experience for the player.
• the yo-yo game may be more interesting and therefore may provide better entertaining experience. Similar to the simple game, the player coils string 110 and throws or flings yo-yo body 100 away or downward. Once string 110 is fully extended the loose loop at the end of string 110 around yo-yo axel 130 allows yo-yo body 100 to continue rotating while string 110 remains fully extended. In yo-yo players' terminology this state of the yo-yo is called a "sleep" state and one may say that the yo-yo "sleeps,” is “sleeping" or such terms.
• yo-yo "sleeps" the player can perform yo-yo "tricks," which are sequences of yo-yo motions that demonstrate the player's skills and agility, all are based on the fact that the rotating yo-yo maintains its orientation as long as it spins fast enough (i.e., the yo-yo preserves its angular momentum, similar to a gyroscope).
• the player may perform a short and sharp flick of the arm, the hand or the finger that causes the loose loop at the end of string 110 around yo-yo axel 130 to tighten due to friction and for string 110 to re-coil around yo-yo axel 130 and therefore for yo-yo body 100 to start rolling upward back to the hand of player.
• This maneuver of the yo-yo is called “waking up” the yo-yo and one may say that the yo-yo "wakes up,” is “waking up” or such terms.
• FIG. 2 is a schematic side-view of a yo-yo with a ball bearing. Similar to the traditional yo-yo, this yo-yo is also made of yo-yo body 100 connected by yo-yo axel 130.
• Ball-bearing 210 comprises an inner ring that is attached to yo-yo axel 130, an outer case to which string 110 is tied tightly and balls or cylinders that can roll between the inner ring and the outer case, allowing low friction relative rotating between the inner ring and the outer case.
• Other devices can also be considered as a ball bearing even without the balls or the cylinders, as long as such devices serve the same purpose of allowing a smooth rotation with minimal friction of an inner part in relation to an outer part.
• Such other devices may use coating by Teflon, silicon, or other polymers or any other method to reduce the friction between the inner part and the outer part of the devices, allowing the smooth rotation with minimal friction between the two parts.
• the ballbearing yo-yo behaves similarly to the traditional yo-yo with a loose loop at the end of string 110 around yo-yo axel 130.
• a ball-bearing yo-yo loses its rotating speed much slower than a traditional yo-yo and the player can perform more yo-yo tricks or may just enjoy a longer "sleep" state time. Therefore, a ball-bearing yo-yo provides an enhanced entertaining experience over a traditional yo-yo.
• All-bearing yo-yos as depicted in FIG. 2 may use roughing of the surface of the inner walls of yo-yo body 100 close to yo-yo axel 130 to assist in creating the initial friction for "waking up" the yo-yo.)
• a wider gap between the two rounded halves of yo-yo body 100 will reduce the friction between string 110 and yo-yo body 100 during the "sleep" state.
• FIG. 3 is a schematic diagram of the devices that may be incorporated in computerized yo-yo 300.
• the physical structure of computerized yo-yo 300 may be similar to the ball-bearing yo-yo depicted in FIG. 2, but computerized yo-yo 300 includes the additional devices described in this specification.

• the core of computerized yo-yo 300 is computation and control device 305.
• Computation and control device 305 is configured to receive measurements that indicate the motion of computerized yo-yo 300 from the sensing devices, accelerometers device 315 and tension-meter device 350, together or separately.
• Computation and control device 305 is configured to generate control signals to control the operation of the elements of computerized yo-yo 300 that enhance the entertaining experience, such as light display device 320, audio play device 325, auxiliary device 330, electric clutch device 335 and electric motor device 340 (the "entertaining elements").
• Computation and control device 305 may also receive feedback information from each of the entertaining elements about their status and functionality.
• Computation and control device 305 may also be connected to communication device 345, which may receive data for computation and control device 305 from an external device and may transmit data from computation and control device 305 to the external device. (Communication device 345 may also send and receive data to and from tension-meter device 350.)
• the external device may be a handheld device such as smartphone or tablet, which may be connected to communication device 345 by a wireless link that may be WiFi (IEEE 802.11 protocol), Bluetooth protocol, or any other communication protocol that provides a communication link between the external device and communication device 345 of computerized yo-yo 300.
• Computation and control device 305 and communication device 345 may be implemented separately or may be implemented using the same solid-state electronic microchip, such as, for example, Texas Instrument CC2541 SimpleLink Bluetooth Smart and Proprietary Wireless MCU.

• Accelerometers device 315 measures the acceleration values of computerized yo-yo 300 and sends the measured acceleration values to computation and control device 305.
• the acceleration values of computerized yo-yo 300 are measurements in a sequence of time of the acceleration at one part or at several different parts of computerized yo-yo 300.
• the acceleration values may indicate the acceleration, the derivative of the acceleration or any other functions or values that can be used to determine the acceleration.
• Accelerometer technology is a well known art. Accelerometer devices are widely available in the marketplace and custom-made accelerometer devices are also common in the industry, in particular accelerometer devices made of piezoceramic materials.
• Accelerometers device 315 may be made of pressure or bending piezoceramic materials, but it may also be made of any mechanical, electrical, piezoelectric, piezoresistive, solid-state or any other technology suitable for manufacturing accelerometers device 315.
• FIG. 4 is a schematic diagram of an optional configuration of the accelerometers in accelerometers device 315 of computerized yo-yo 300 (Fig. 4 is not to scale). Accelerometers device 315 may be placed at the center of yo-yo body 100. The four individual accelerometer components in FIG. 4 are marked by 41 OA, 410B, 4 IOC and 410D, but any number of accelerometer components may be used. Each of accelerometer components 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 the acceleration in one direction, which in FIG. 4 is the radial direction.
• yo-yo body 100 rotates around yo-yo axel 130 and rolls up and down, but does not move sideways, the configuration depicted in FIG. 4 may be sufficient to measure the acceleration values of these motions. However, since the yo-yo might "wobbles" out of control it may be also beneficial to measure the acceleration perpendicular to the main rotating plane of the yo-yo.
• accelerometer components 410A-410D in FIG. 4 are each a single accelerometer unit and therefore each can measure only the acceleration values in one direction (the radial direction)
• an additional accelerometer component (not shown in FIG. 4) may be used to measure the acceleration values perpendicular to the main rotating plane of the yo-yo.
• the additional accelerometer component may have different characteristics than of accelerometer components 410A-410D, since the perpendicular acceleration values are expected to be much smaller than the radial acceleration values.
• the acceleration values depend on the motion of computerized yo-yo 300 as it is played and the goal of measuring the acceleration values is to extract the information about the motion of computerized yo-yo 300.
• the extracted information may be used to apply control to the entertaining elements and may be sent to an external device for further analysis, storage or display.
• the motion information may be the acceleration at any part of computerized yo-yo 300, the derivative of the acceleration at any part of computerized yo-yo 300, the position of the center of computerized yo-yo 300, the speed of the center of computerized yo-yo 300, the rotating speed of computerized yo-yo 300, or any other information that may be used to control the entertaining elements or that may be used for further analysis, storage or display by the external device.
• the measured acceleration values may be used to extract the information about the state of computerized yo-yo 300, where a state is an event in time in which computerized yo-yo 300 is in a particular position, moves in a particular motion or is used a particular game configuration, as will become clear by the following example.
• the example is of a ball-bearing yo-yo game that includes the following sequence of seven states:
• FIG. 5 shows an example of an acceleration curve, which is the representation of the accelerometer values against time, for one of accelerometer components 410A-410D for the game sequence listed above.
• the x-axis in FIG. 5 is the time in ms units and the y-axis is the acceleration values in m/s units.
• State 1 During state 1, marked by SI in FIG. 5, the acceleration values will be very small (with the exception of possible short but high acceleration peaks if the yo-yo is banged against some other object, firmly placed in the hand, falling and hitting the floor, etc.). State 1 may be detected by the low level of the average of the median-filtered acceleration values.
• State 2 marked by S2 in FIG. 5, the player flings the yo-yo with a sharp movement of the arm, the hand or the wrist to accelerate the yo-yo away or downward.
• the acceleration at this step is characterized by a smooth curve, where the amplitude of the curve and its slowly varying slop (the derivative of the acceleration) depend on the player strength and technique.
• State 2 may be detected by the significant increase in the average of the acceleration values without acceleration spikes.
• State 3 starts when the arm, the hand or the wrist flinging movement ends, the yo-yo is released from the hand of the player and starts rolling downward at a fast speed.
• the acceleration values measured by a radially-placed accelerometer component can reach 1500 m/s or even higher values.
• the gravitational pull causes the rotating speed of the yo-yo to increase.
• the rotation of the yo-yo is indicated in segment S3 by the semi-periodical perturbations, caused by the earth gravitational pull, which affects the accelerometer component at an opposite direction each half rotation.
• the increase in the rotating speed is indicted by the increase in the amplitude of the acceleration values and by the shortening of the time intervals between the semi-periodical perturbations.
• State 3 may be detected by the significant instantaneous increase in the derivative of the acceleration curve followed by the semi-periodical perturbations with increased average amplitude and increased frequency, which may be detected by identifying the minimum and the maximum points on the acceleration curve.
• State 4 happens as the string becomes fully extended and its pull stops the downward motion of the yo-yo.
• S4 the abrupt break in the yo-yo downward motion will result in very strong peaks in the acceleration curve.
• the actual values of the acceleration peaks in segment S4 depend on several factors, such as the strength of the initial fling, the mass of the yo-yo and the elasticity of the string. State 4 may be detected by the very large peaks in the acceleration curve.
• State 5 is the "sleep" state and is indicted by segment S5 in FIG. 5. Similar to the later part of state 3, the acceleration curve of state 5 exhibits the semi-periodical perturbations caused by the earth gravitational pull. The slow reduction of the rotating speed due to friction is indicated by the slow decrease in the amplitude of the acceleration curve and the increase of the time intervals between the semi-periodical perturbations. The length of the S5 segment will likely be much longer than the length depicted in FIG. 5 and it may be possible for the yo-yo player to perform other yo-yo motions (yo-yo tricks) that start from the "sleep" state of the yo-yo. State 5 may be detected by the smooth average of the acceleration curve and by identifying the minimum and the maximum points on the acceleration curve.
• State 6 which is marked by S6 in FIG. 5, happens when the player decides to return the yo-yo to the hand and performs a short downward and upward flick of the arm, the hand or the finger to "wake up" the yo-yo.
• the short downward motion releases the string and the short upward motion tightens a loop and/or creates a knot near enough to the inner walls of the yo-yo body, which causes the re-coiling of the string around the axel that result in the yo-yo upward motion.
• the initial downward flick may create a short reduction of the difference between the acceleration minimum points and maximum points since the yo-yo will be in a short near-free-fall condition.
• State 7 which is marked by S7 in FIG. 5, is the rolling up of the yo-yo.
• the acceleration curve exhibits the same periodical perturbations as in states 3 and 5.
• State 7 may be detected by a significantly lower variance of the acceleration values in comparison to state 6.
• FIG. 5 demonstrates that the information about the yo-yo motion and states may be determined by analyzing the acceleration values.
• the analysis requires the extraction of parameters such as the derivative of the acceleration, the locations and values of the maximum and the minimum points, the locations of changes in the parameters, etc.
• Such parameters may be used to extract (i.e., calculate) other parameters, such as the position of the center of the yo-yo, the speed of the center of the yo-yo, the rotating speed of the yo-yo, or any other parameter that may be used to control the yo-yo or that provides information about its position, motion or states.
• the acceleration curve for one of accelerometer components 410A-410D provides an example of the acceleration curve for one of accelerometer components 410A-410D, but the acceleration values from different accelerometer components may be combined and used for the analysis of the yo-yo position, motion or states. For example, the averaging of the acceleration values from all of accelerometer components 410A-410D may provide information about the motion of the center of the yo-yo.
• state parameters we will call the parameters described above by "state parameters" and they may be extracted by computation and control device 305 to be used for the control of other devices in computerized yo-yo 300, or they may also be transmitted using communication device 345 to an external device.
• the state parameters may initially be any of the parameters that are extracted based on the acceleration values, including, but not limited to, the acceleration values themselves.
• tension-meter device 350 may help in improving the detection of the yo-yo motion and states by measuring the tension at the end of string 110 near holding band 120 and providing the tension values to computation and control device 305.
• Tension-meter device 350 may be comprised of a single piezoceramic element, but it may be made of any mechanical, electrical, piezoelectric, piezoresistive, solid-state or any other technology required for manufacturing tension meter 350.
• the supply of power and the data transmission may be made through string 110, or tension-meter device 350 may include a micro battery for power supply and may include an auxiliary communication device to communicate with yo-yo communication device 345.
• tension-meter device 350 may show significant increase in the tension values at the beginning of states 3, 4 and 6 and therefore it may assist in the detection of the starting instances of these states. Therefore, the state parameters may also include the tension values and any of the parameters that are extracted based on the tension values.
• Computation and control device 305 may use the acceleration values from accelerometers device 315 (or the tension values from tension-meter device 350, together or separately), the extracted state parameters and received setup parameters (discussed in the sequel) to generate control signals for the operating of the entertaining elements in computerized yo-yo 300, such as light display device 320, audio play device 325, auxiliary device 330, electric clutch device 335 and electric motor device 340.

• FIG. 11 is a schematic diagram of computerized yo-yo 300 with ball-bearing 210 and electric clutch device 335. Similar to the ball-bearing yo-yo described in FIG. 2, this embodiment of computerized yo-yo 300 includes ball-bearing 210 with an inner ring attached to yo-yo axel 130 and an outer case.
• Electric clutch device 335 may be made of piezoelectric clutch components 1105 that may be attached to yo-yo body 100 and placed at about the same distance from yo-yo axel 130 as the outer case of ball-bearing 210. Piezoelectric clutch components 1105 may be expended or contracted by applying (or un-applying) electrical signals. FIG. 11 depicts four clutch components 1105, two at each side of yo-yo body 100, but any number of clutch components 1105 at any configuration may be used. Moreover, any other technology may be used to implement clutch components 1105, such as, but not limited to, magnetic, electromagnetic or electromechanical technologies. Other elements required for the operation of electric clutch device 335 and clutch components 1105, such as, but not limited to, wiring, switches, power amplifiers or any other element are not shown in FIG. 11.
• Clutch components 1105 may be configured such that they contract when an electric signal is applied (or when an electric signal is un-applied), eliminating any contact or friction between clutch components 1105 and the outer case of ball-bearing 210, which we will call “unlocked.” Clutch components 1105 may be further configured such that they expend when an electric signal is un-applied (or when an electric signal is applied), creating contact and friction with the outer case of ball-bearing 210, which we will call “locked.” The contact and friction between clutch components 1105 and the outer case of ball-bearing 210 create a friction force between yo-yo body 100 and the outer case of ball-bearing 210, in the sense that this force affects (slows) the relative motion between yo-yo body 100 and the outer case of ball-bearing 210.
• the friction force may be used to control the relative motion between yo-yo body 100 and the outer case of ball-bearing 210 and therefore also between yo-yo body 100 and string 110.
• clutch components 1105 are unlocked, the outer case of ball-bearing 210 is free to rotate, which means that the motion of computerized yo-yo 300 will be identical to the motion of the ball-bearing yo-yo described in FIG. 2.
• clutch components 1105 when clutch components 1105 are locked the outer case of ball-bearing 210 will rotate together with yo-yo body 100, which means that the motion of computerized yo-yo 300 will be similar to the motion described for the simple yo-yo in FIG.
• control signals for electric clutch device 335 may be based on the acceleration values from accelerometers device 315 (or the tension values from tension-meter device 350, together or separately), the state parameters extracted by computation and control device 305, or the setup parameters received from an external device, together or separately.
• the electric clutch control signals may control clutch components 1105 to be locked as the player throws computerized yo-yo 300 and then the electric clutch control signals may control clutch components 1105 to be unlocked exactly when string 110 is fully extended, as indicated by the acceleration values from accelerometers device 315 (or the tension values from tension-meter device 350, together or separately). This will result in a higher efficiency, in the sense of increased rotating speed during "sleep" state, in comparison to the ball-bearing yo-yo described in FIG. 2.
• the electric clutch control signals may control clutch components 1105 to be unlocked and computerized yo-yo 300 may be in a "sleep" state, and then the acceleration values from accelerometers device 315 (or the tension values from tension-meter device 350, together or separately) may indicate that the player is "waking up" the yo-yo, which may cause computation and control device 305 to generate the electric clutch control signals to control clutch components 1105 to be locked.
• computerized yo-yo 300 may be in a "sleep" state with clutch components 1105 unlocked when the player issues a voice command to the external device, such as pronouncing the word "up.”
• the voice command may be recognized by the external device that can send suitable setup parameters via communication device 345 to computation and control device 305, which may then generate the electric clutch control signals to control clutch components 1105 to lock, which will cause computerized yo-yo 300 to start rolling upward.
• the re-coiling is not simple, since the player needs to carefully manipulate string 110 to generate the initial friction that will allow the re-coiling to happen.
• the player may simply issue a voice command, such as "lock," to the external device.
• the voice command may be recognized by the external device that can send suitable setup parameters via communication device 345 to computation and control device 305, which may then generate the electric clutch control signals to control clutch components 1105 to lock.
• clutch components 1105 may be locked based on the recognition of a first motion pattern.
• clutch components 1105 Once clutch components 1105 are locked the player can easily re-coil string 110, issue a second voice command such as "unlock,” which will result in the unlocking of clutch components 1105, and then the player can simply re-start the yo-yo game. Similarly, clutch components 1105 may be unlocked based on the recognition of a second motion pattern.
• varying levels of electric clutch control signals for clutch components 1105 in electric clutch device 335 it may be possible to create varying degree of friction between clutch components 1105 and the outer case of ball-bearing 210 and therefore a varying degree of the friction force between yo-yo body 100 and the outer case of ball-bearing 210.
• the varying degree of friction force may be used for smooth control of computerized yo-yo 300 motion, such as gradually slowing the rotating speed of computerized yo-yo 300 or controlling the rotating speed of computerized yo-yo 300 as it moves upward when it "wakes up.”
• FIG. 12 describes computerized yo-yo 300 where the outer case of ball-bearing 210 is further fitted with internal disks 1220 that help to resolve this issue. Similar to FIG. 11, this computerized yo-yo 300 also includes electric clutch device 335 implemented by clutch components 1105.
• clutch components 1105 may be controlled by computation and control device 305, it may be possible to "wake up" computerized yo-yo 300 depicted in FIG. 12 by the locking of clutch components 1105.
• string 110 and internal disks 1220 do not move relative to one another during the "sleep" state and therefore the friction of string 110 with the internal walls of yo-yo body 100 during the "sleep” state is eliminated.
• computerized yo-yo 300 depicted in FIG. 12 with internal disks 1220 may be more efficient in the sense that it may rotate longer during "sleep” state.
• Other elements required for the operation of electric clutch device 335 and clutch components 1105 such as, but not limited to, wiring, switches, power amplifiers and any other element are not shown in FIG. 12.

• Electric motor 1310 may have an inner component (equivalent to the inner ring of ball-bearing 210) that may hold electrical coils and an outer case (equivalent to the outer case of ball-bearing 210) that may hold fixed magnets. Assuming that clutch components 1105 are unlocked, when no control signals are applied to electric motor 1310 the inner component may rotate smoothly and with minimal friction in relation to the outer case, similar to ball-bearing 210. When control signals are applied to electric motor 1310, a rotating force may be generated between the inner component and the outer case of electric motor 1310.
• the generated rotating force is also applied between the outer case of electric motor 1310 and yo-yo body 100. If yo-yo body 100 and the outer case of electric motor 1310 are not initially rotating relative to each other, the rotating force may generate a rotating motion between them. If yo-yo body 100 and the outer case of electric motor 1310 are already rotating relative to each other, the rotating force may increase or may decrease the speed of this rotation, or the rotating force may even reverse the direction of this rotation.
