Description

Computerized yo-yo

This application claims the benefit of priority from US Provisional Application No. US 61/940,853, filed on February 18, 2014.

The present invention relates to a computerized yo-yo toy. The computerized yo-yo includes devices that delight the yo-yo user with programmable lighting, sound and other functions that operate according to their movements and conditions. In addition, the computerized yo-yo may include devices for controlling the movement of the computerized yo-yo, such as, for example, an electric clutch and an electric motor.

The yo-yo is one of the oldest toys. Although believed to have originated in China, the first recorded yo-yo toys appear in Greek paintings around 500 BC. Modern yo-yo toys use the same concepts as ancient yo-yo toys, but can be made of modern materials (eg, plastic or metal alloy) and have different shapes (eg, butterfly-shaped yo-yos). and may include modern mechanical technology (eg, rotating ball bearings).

Some commercially available yo-yo toys may include electronic components in addition to mechanical components. Conventional yo-yo toys include a battery, a light, and a mechanism to turn the light on and off for additional interest. Adding this more advanced concept and some variant structures, such as sound reproduction, LCD display, control and feedback, etc. is, for example, US Pat. Nos. 4,327,518, 5,145,444, 5,356,328, 5,791,966. Nos. 6,287,193, 6,634,922 and 6,695,670.

Some commercially available yo-yo toys may also include improved mechanical components to further enhance the fun of playing with the yo-yo toy. For example, the yo-yos currently on the market include a centrifugal mechanical clutch that opens when the yo-yo rotates very quickly, long "slips" (fast rotation of the yo-yo at the end of the string) and automatic "wake-" up" (quick return of the yo-yo to the user's hand from the "sleep" position). Further improved combinations of mechanical and electrical components that allow for improved control of such yo-yo movement are described in US Pat. Nos. 7,448,934 and 8,187,052.

The purpose of any game is to entertain its users. Therefore, a game with many features and options can be more fun, i.e. provide a better fun experience. 1 shows a schematic diagram of a simple conventional yo-yo. The conventional yo-yo body 100 may be made of a conventional material such as wood or ceramic, or a modern material such as a metal alloy, plastic or other material. The yo-yo body 100 is made up of two round halves, which may be flat, spherical, conical, or any other suitable round shape. The yo-yo accelerator 130 connects the two round halves of the yo-yo body 100, and thus the yo-yo exhibits a symmetric-radial shape suitable for a rotating toy. One end of the string 110 is attached to the yo-yo accelerator 130 , and the other end is connected to the fixing ring 120 . Retaining ring 120 may be made of any suitable material, or may be in the form of a simple ring formed at the end of string 110 . The end of the string 110 attached to the yo-yo accelerator 130 may be firmly connected or may form a loose ring around the yo-yo accelerator 130 .

If the end of the string 110 is tightly connected to the circumference of the yo-yo accelerator 130, the yo-yo game is very simple. First, the user winds the string 110 in a narrow groove between the two round halves of the yo-yo body 100 (the term “winding” or “rewinding” means herein the yo-yo accelerator 130 or other part of the yo-yo It is used to describe a cloud of strings 110 around the perimeter of , which is to create multiple overlapping loops of strings 110, as needed at the beginning of the game (which will be described in detail later). Next, the user throws or sends the yo-yo body 100 away or down while holding the fixing ring 120 . The pulling force generated by the extension of the wound string 110 rotates the yo-yo body 100, and when the string 110 is completely unwound, it itself starts to be wound around the yo-yo accelerator 130 again. , the yo-yo body 100 rolls upward again toward the user's hand and rises, so that the user can hold the yo-yo. The user may also use hand movements to add inertia to the yo-yo and repeat the up-and-down movement of the yo-yo. These yo-yo games provide users with a limited fun experience.

On the other hand, if the end of the string 110 forms a loose loop around the yo-yo accelerator 130, the yo-yo game can be more fun, and thus a better fun experience can be provided. Similar to the simple above game, the user winds the string 110 and throws or sends the yo-yo body 100 away or down. Once the string 110 is fully extended, the loose loop located at the end of the string 110 around the yo-yo accelerator 130 causes the yo-yo body 100 to rotate while maintaining the string 110 fully extended. allows you to continue In terms of yo-yo users, this state of yo-yo is called a “sleep” state, and people use this yo-yo “sleep” as “sleeping” or similar terms. Like the yo-yo "slip" above, the user can perform a yo-yo "trick", which is a sequence of yo-yo movements that demonstrates the user's skill and agility, all of which are as long as the rotating yo-yo is spinning fast enough. It is based on the fact that it retains its directionality (ie, a yo-yo preserves its angular momentum, similar to a gyroscope). When the setting of the trick is completed, the user executes a short and sharp movement of the arm, hand or finger so that the loose loop at the end of the string 110 positioned around the yo-yo accelerator 130 is tightened by friction and , so that the string 110 is rewound around the yo-yo accelerator 130 , and thus the yo-yo body 100 is rolled upward toward the user's hand. This operation of a yo-yo is called a yo-yo "wake-up", and people use this yo-yo "wake-up" as a "wake-up" or similar term.

Of course, in the "slip" state, the yo-yo is the friction between the loose loop of the end of the string 110 and the yo-yo accelerator 130 , and between the string 110 and the inner wall of the two halves of the yo-yo body 100 . Friction may lose some of its rotational speed. Modern yo-yo toys may use ball bearings to reduce the loss of their rotational speed in a "slip" state. 2 is a schematic side view of a yo-yo with a ball bearing; Like the conventional yo-yo, the yo-yo is composed of the yo-yo body 100 connected by the yo-yo accelerator 130 . However, for this yo-yo, the ball bearing 210 is disposed around the yo-yo accelerator 130 . The ball bearing 210 includes an inner ring attached to the yo-yo accelerator 130, an outer case to which the string 110 is rigidly connected, and rotation between the inner ring and the outer case to allow relatively low friction. Balls or cylinders. Other devices without said balls or cylinders may also be referred to as ball bearings, and such devices may be considered the same as long as they serve the same purpose of minimizing friction of the inner part with respect to the outer part and allowing smooth rotation. there is. Such other devices may use coatings with Teflon, silicone or other polymers, or may use other methods of reducing friction between the inner and outer parts of the device to allow smooth rotation with minimal friction between the two parts. there is. Of course, it is also possible to assemble the ball bearing 210 so that the yo-yo accelerator 130 forms an inner ring of the ball bearing 210 . This ball bearing type yo-yo operates similarly to a conventional yo-yo having a loose loop at the end of the string 110 around the yo-yo accelerator 130 . However, since the ball bearing 210 almost eliminates the friction between the string 110 and the yo-yo accelerator 130, the ball bearing type yo-yo loses much less of its rotational speed than the conventional yo-yo, and the user You can do the trick well, or you can enjoy a longer "sleep" time. Therefore, the ball bearing type yo-yo provides an enhanced and fun experience compared to the conventional yo-yo.

A ball bearing yo-yo can maintain its rotational speed more than a conventional yo-yo, but the "wake-up" of a ball-bearing yo-yo is generally more difficult than the "wake-up" of a conventional yo-yo. A short movement of the hand sufficiently increases the friction of the ball bearing to form small new loops and/or knots of the string 110 , and the new loops and/or knots of the string 110 cause the new loops and/or knots to form on the inner wall of the yo-yo body 100 . It is necessary to ensure that it creates sufficient initial friction with one of the yo-yos to start rewinding the string 110 around the accelerator 130, thereby reliably causing the upward rolling action of the yo-yo ( The ball-bearing yo-yo shown in FIG. 2 can be used to help create the initial friction to "wake up" the yo-yo by using the inner wall surface roughness of the yo-yo body 100 proximate the yo-yo accelerator 130. there is). This presents an interesting dilemma in the design of ball-bearing yo-yos. On the one hand, the wide spacing between the two round halves of the yo-yo body 100 will reduce the friction between the string 110 and the yo-yo body 100 in a “slip” state. On the other hand, however, too wide a gap can make the "wake up" of the yo-yo more difficult because more "picky" movement of the hand is between the string 110 and the inner wall of the yo-yo body 100 . This is because it may be required to generate sufficient initial friction. This dilemma is alleviated by some embodiments of the present invention.

3 is a schematic diagram of devices that may be included in a computerized yo-yo 300 . The physical structure of the computerized yo-yo 300 may be similar to the ball bearing type yo-yo shown in FIG. 2 , but the computerized yo-yo 300 includes additional devices as described herein. The invention may be implemented with an operating subset of the devices as shown in FIG. 3 , or may be implemented with all of the devices shown in FIG. 3 .

The core of the computerized yo-yo 300 is an operation and control unit 305 . The computation and control device 305 is configured to receive measurements indicative of motion of the computerized yo-yo 300 , either together or separately from the sensing device, the accelerometer device 315 and the tensiometer devices 350 . The calculation and control device 305 may include, for example, an optical display device 320 , a sound reproducing device 325 , an auxiliary device 330 , an electric clutch device 335 , and an electric motor device 340 (“fun element”). "), and is configured to generate control signals that control the operation of elements of the computerized yo-yo 300 that enhance the fun experience. The computation and control unit 305 may receive feedback information from each interesting factor about its state and function. The arithmetic and control device 305 may be connected to a communication device 345 capable of receiving data for the arithmetic and control device 305 from an external device, and data from the arithmetic and control device 305 to the external device. (communication device 345 may send and receive data from tension-meter device 350). The external device is connected via a wireless link, which may be Wi-Fi (IEEE 802.11 protocol), Bluetooth protocol, or other communication protocol that provides a communication link between the external device and the communication device 345 of the computerized yo-yo 300 . It may be a portable device, such as a smart phone or tablet, that may be connected to the communication device 345 . Calculation and control unit 305 and communication unit 345 may be implemented separately, or may be implemented in the same solid-state electronic microcontroller, such as, for example, a Texas Instruments CC2541 SimpleLink Bluetooth Smart and Proprietary wireless MCU. It may be implemented using a chip.

The battery 310 provides power to other devices in the computerized yo-yo 300 and is connected to other devices included in a specific embodiment of the computerized yo-yo 300 . The connection of the battery is not shown in detail in FIG. 3 for the sake of brevity. One or more batteries may be used within the computerized yo-yo 300 . The battery 310 may be charged as a wired or wireless power supply, or may be charged using an electric motor device 340 such as a generator.

The accelerometer device 315 measures the acceleration value of the computerized yo-yo 300 , and sends the measured acceleration value to the calculation and control device 305 . The acceleration values of the computerized yo-yo 300 are a series of time acceleration measurements in one part of the computerized yo-yo 300 or in different parts. The acceleration value may represent acceleration, a derivative of acceleration, or any other function or values that may be used to determine acceleration. Accelerometer technology is a well-known technology. Accelerometer devices are widely available in the market, and custom accelerometer devices are also common in the industry, in particular the accelerometer devices are made of piezoelectric ceramic material. The accelerometer device 315 may be fabricated by pressing or bending a piezoelectric ceramic material, but may also be fabricated with all mechanical, electrical, piezoelectric properties, piezoresistive, solid-state, or any other technique suitable for fabricating the accelerometer device 315 . it might be

4 is a schematic diagram of an optional configuration of an accelerometer in an accelerometer device 315 of a computerized yo-yo 300 ( FIG. 4 is not to scale). The accelerometer device 315 may be disposed at the center of the yo-yo body 100 . Although four separate accelerometer components 41OA, 410B, 410C and 410D are shown in FIG. 4, any number of accelerometer components may be used. Each of the accelerometer components 410A-410D may be one accelerometer device comprising three different accelerometer units (one for each spatial dimension), or for measuring acceleration in either direction, the radial direction in FIG. 4 . It may be one accelerometer unit. If the yo-yo body 100 rotates around the yo-yo accelerator 130 and rolls up and down but does not move sideways, the configuration shown in FIG. 4 may be sufficient to measure the acceleration value of this movement. there is. However, since yo-yos can create "wobbles" out of control, it can be helpful to measure acceleration perpendicular to the yo-yo's main plane of rotation. If the accelerometer components 410A-410D shown in FIG. 4 are each one accelerometer unit, and therefore each of them only measures an acceleration value in one direction (radial direction), an additional accelerometer component (not shown in FIG. 4 ) is used to measure an acceleration value perpendicular to the main rotational plane of the yo-yo. The additional accelerometer component may have different characteristics than the accelerometer component 410A-410D, since vertical acceleration values are expected to be significantly smaller than the radial acceleration values.

The acceleration value depends on the movement when the computerized yo-yo 300 is used, and the purpose of measuring the acceleration value is to extract information on the movement of the computerized yo-yo 300 . The extracted information can be used to apply controls to the fun factor and transmitted to an external device for further analysis, storage or display. The motion information may be an acceleration in all parts of the computerized yo-yo 300, an acceleration derived value in all parts of the computerized yo-yo 300, a central position of the computerized yo-yo 300, and a computerized yo-yo 300 ), the rotational speed of the computerized yo-yo 300, or any other information that may be used to control the fun factor, or may be used for further analysis, storage, or display by the external device.

The measured acceleration value may be used to extract information about the state of the computerized yo-yo 300, where one state is that the computerized yo-yo 300 is in a specific position, moves to a specific movement, or is configured for a specific game. It is a time event when used as or is, and will be clearly understood by the following example. This example is from a ball-bearing yo-yo game, and includes the following sequence of seven states:

State 1: Catch a yo-yo

State 2: User throws a yo-yo

State 3: Yo-Yo downward movement

State 4: Downshift stop at end of line

State 5: "Sleep" state

State 6: Short tug of string to "wake-up" the yo-yo

State 7: yo-yo upward movement

Fig. 5 shows an example of an acceleration curve, which represents a representation of the acceleration values over time for one of the accelerometer components 410A-410D for the game sequences listed above. In FIG. 5 , the X-axis is time in milliseconds (ms), and the Y-axis is acceleration values in m/s ² .

During state 1, as indicated by S1 in Fig. 5, the acceleration values are very small (if the yo-yo collides with another object, is held firmly in the hand, or falls on the floor, a very short but high acceleration peak is except). State 1 may be detected as a lower level of the average of the filtered acceleration values with a median value.

During state 2, as indicated by S2 in FIG. 5 , the user throws the yo-yo with a sharp movement of the arm, hand, or wrist in order to accelerate the yo-yo away or downward.

The acceleration in this state is characterized by a gentle curve, where the curve's amplitude and slowly changing slope (a derivative of the acceleration) depend on the strength and skill of the user. State 2 can be detected by a significant increase in the average of the acceleration values without a sharp increase in acceleration.

State 3 starts when the throwing operation of the arm, hand or wrist ends, and the yo-yo is released from the user's hand and starts rolling down at a high speed. In this state, as indicated by S3 in Fig. 5, the acceleration value measured by a radially positioned accelerometer component (similar to that shown in Fig. 4) can reach 1500 m/s ² , or higher. there is. When the yo-yo moves downward, the pulling force of gravity increases the rotation speed of the yo-yo. The rotation of the yo-yo is represented in segment S3 by a semi-periodic perturbation and is caused by the pulling force of the earth's gravity, which affects the accelerometer component at each half-turn in the opposite direction. An increase in the rotational speed is indicated by an increase in the amplitude of the acceleration value and by a shortening of the time intervals between the semi-periodic perturbations. State 3 can be detected by a significant instantaneous increase within the derivative value of the acceleration curve, followed by a semi-periodic perturbation with an increased average amplitude and an increased frequency, which results in the minimum and maximum points on the acceleration curve. It may be detected by identifying.

State 4 occurs when the string is fully extended and its pulling stops the downward movement of the yo-yo. At this stage, as indicated by S4 in Fig. 5, a sharp break in the downward movement of the yo-yo will generate a very strong peak in the acceleration curve. The actual value of the acceleration peak in segment S4 depends on several factors such as, for example, the strength of the initial throw, the mass of the yo-yo and the elasticity of the string. State 4 can be detected by a very large peak of the acceleration curve.

State 5 is the "sleep" state, indicated by segment S5 in FIG. 5 . Similar to the latter half of state 3, the acceleration curve in state 5 shows semi-periodic perturbations caused by the gravitational pull of the Earth. A slow decrease in rotational speed due to friction is indicated by a slow decrease in the amplitude of the acceleration curve and an increase in the time interval between semi-periodic perturbations. The length of the S5 segment is much longer than the length shown in Figure 5, which will allow the user of the yo-yo to perform different movements of the yo-yo (yo-yo trick) starting from the "sleep" state of the yo-yo. State 5 can be detected by identifying the smooth average value of the acceleration curve and the minimum and maximum points of the acceleration curve.

State 6 occurs when the user decides to return the yo-yo to the hand and performs short descending and ascending movements of the arm, hand, or finger to “wake-up” the yo-yo, as indicated by S6 in FIG. 5 . . A short descending movement releases the string, a short ascending movement tightens the loop, and/or creates a knot close enough to the inner wall of the yo-yo body, causing the string to rewind around the accelerator, resulting in the yo-yo ascending movement do. The initial descending bouncing can make a short decrease in the difference between the minimum and maximum points of acceleration, since the yo-yo will be in almost a short free fall state. It will be followed by sharp peaks in the acceleration curve due to abrupt changes in yo-yo motion. The onset of state 6 can be detected by a short decrease in the difference between the minimum and maximum points of the acceleration curve, followed by large peaks in the acceleration curve.

State 7 is the rising cloud of the yo-yo, as indicated by S7 in FIG. 5 . The acceleration curve shows the same periodic perturbations as in State 3 and State 5. State 7 can be detected by a very low change in acceleration values compared to state 6.

5 shows that information on yo-yo motion and state can be determined by analyzing the acceleration values. The analysis requires the extraction of parameters such as, for example, acceleration derivative values, the positions and values of the maximum and minimum points, and the location of changes in the parameters, and the like. Such parameters may be used to control other parameters, e.g., the yo-yo's central position, the yo-yo's central velocity, the yo-yo's rotational speed, or the yo-yo to provide information about its position, movement or state. It can be used to extract (i.e. calculate) other parameters that exist. 5 provides an example of an acceleration curve for one of the accelerometer components 410A-410D, acceleration values from other accelerometer components may be combined and used for analysis of yaw position, motion or state. For example, an average of acceleration values from all accelerometer components 410A-410D may provide information about the movement of the yo-yo center. We will refer to the parameters described above as “state variables”, which can be extracted by the computation and control unit 305 for use in the control of other devices within the computerized yo-yo 300, or It may be transmitted to an external device using the communication device 345 . The state parameters may be all parameters that are initially extracted based on the acceleration values, including, but not limited to, the acceleration values themselves.

It is possible to use a low precision accelerometer, which may be cheaper, as long as an interesting goal can be achieved in the computerized yo-yo 300 . Although such low precision accelerometers cannot always provide measurements of acceleration values with the precision required to determine the exact position and precise movement of the computerized yo-yo 300, such low precision accelerometers have sufficient accuracy. With , it is possible to sufficiently extract the state parameters.

Using a tensiometer device 350 can help to improve detection of yo-yo motion and condition, measure the tension at the end of the string 110 near the fixation band 120, and measure the tension value is executed by providing the arithmetic and control unit 305 . Tensiometer device 350 may be comprised of one piezoelectric ceramic element, but it may be manufactured with all mechanical, electrical, piezoelectric properties, piezoresistive, solid-state, or any other techniques necessary to fabricate tensiometer 350 . can be Power supply and data transmission may be via line 110 , or tensiometer device 350 may include a micro-battery for power supply, and may include an auxiliary communication device for communicating with yo-yo communication device 345 . may include In particular, the tensiometer device 350 may exhibit a large rise in the tension value at the beginning of states 3, 4, and 6, and thus it may help detect instances of onset of these states. Accordingly, the state parameters may include tension values and all parameters extracted based on the tension values.

Calculation and control unit 305 is configured to calculate acceleration values from accelerometer device 315 (or together or separately with tension values from tensiometer device 350 ), the extracted state parameters, and received setting parameters. Using variables (described below), for example, the light display device 320 , the sound reproduction device 325 , the auxiliary device 330 , the electric clutch device 335 and the electric motor device 340 . , it is possible to generate control signals for the operation of the fun elements in the computerized yo-yo 300 .

The optical display device 320 may include any number of light emitting components 720 , such as, but not limited to, LEDs or lasers, which are disposed anywhere on the inside or surface of the yo-yo body 100 . can be The light display device 320 also includes wires, electrical switches, dimmers, power amplifiers, or any other components, and all of the necessary connection components between these components used to operate the light emitting components 720 . can do. The components of the optical display device 320 may be installed inside or anywhere inside the yo-yo body 100 . In addition, the optical display device 320 may be implemented as a removable device, as will be described below. Some examples of operating the light display device 320 are that when the computerized yo-yo 300 is stationary (state 1), it emits a low or soft light, and the computerized yo-yo 300 is thrown (state 2). to state 3), when the end of the string 110 is reached (state 4), or when “wake-up” (state 6), the light may flash, but is not limited thereto. In another example, based on the structure of the light emitting component 720 and the movement and state of the computerized yo-yo 300, light synchronized with the movement of the yo-yo may provide a fun effect, for example, a computerized yo-yo A flash of light indicating a stationary state despite the rotation of 300 , or may provide an indication of a figure or characteristic that may appear stationary, or may move in an interesting pattern. Further, in synchronization with the sound reproducing apparatus 325 , the light display may be operated in synchronization with the beat and/or intensity of the sound reproduced by the sound reproducing apparatus 325 . The light pattern may be fixed, or it may be changeable, loadable, or programmable, as will be described below.

Sound reproduction device 325 is comprised of electrical, electro-mechanical, electronic or piezoelectric components that can be used to produce audible sound. Combine these components with high performance speakers, memory components used to hold pre-stored or loaded sound files or sound formats (eg MIDI, etc.), digital-to-analog converters, power amplifiers, or any other components; It includes the necessary connecting parts between these parts. The components of the sound reproducing apparatus 325 may be located inside or anywhere in the yo-yo body 100 . The sound reproduction device 325 may be implemented as a removable device, as described below. The sound reproducing apparatus 325, when the user plays with the computerized yo-yo 300, generates interesting sounds, for example, music, sound effects, human voices, animal sounds, or other fun and exciting sounds and sounds. can be used to play. Some examples of operating the sound reproducing device 325 are when the computerized yo-yo 300 is in a stationary state (state 1), playing soft music, and the computerized yo-yo 300 is thrown (state 2). to state 3), reaching the end of the string 110 (state 4), or "wake-up" (state 6), a very loud thump sound may be reproduced, but is not limited thereto. In another example, the sound may be reproduced with a beat corresponding to the rotation speed of the computerized yo-yo 300 . Interesting acoustic information, for example recorded sounds (music, voice, sounds, etc.), MIDI format data or other acoustic data, etc., may be constant or pre-stored in a memory element, or such acoustic information may be changeable or , loadable, or programmable as described below.

Fixed fun elements, for example, disposing the optical display device 320 on one side of the computerized yo-yo 300, and installing the sound reproducing device 325 on the other side of the computerized yo-yo 300, Or even a computerized yo-yo 300 equipped with a combination of a light display device 320 and a sound reproducing device 325 on each side of the computerized yo-yo 300 and installed together, or other arrangements and configurations of such fun elements. It is possible to manufacture the yo-yo 300 . However, the enhanced fun experience is that if these fun elements (as well as the auxiliary devices 330, which will be described in more detail below) are made removable so that various other types of removable devices are attached to the computerized yo-yo 300, If it can be replaced with another removable device if necessary, it will be more interesting to obtain.

6A, 6B and 6C show possible implementations of a latching base 605 that can be assembled within the yo-yo body 100 , in particular for a removable device that is assembled to either or both of the round halves of the yo-yo body 100 . . The latching base 605 may be formed by a concave space in the yo-yo body 100, and the removable device is inserted into the latching base 605 and held fixed by the latches 61OA, 610B, 61OC, and 610D. can be The latching base 605 may also include a connection pad 615 and a padding ring 620 . The connection pad 615 in the latching base 605 may be made of a metal strip such as copper to provide electrical signals and power from the yo-yo body 100 to removable devices fixed to the latching base 605 . Padding ring 620 may be formed of rubber or silicone to provide cushioning and resistance. One of the latches, eg, latch 61OA, may be configured to be movable, wherein a biasing spring 630 may push latch 610A toward the center of latching base 605 . The removable device is inserted into the latching base 605 under the latches 610B, 610C, and 610D, and when pushed by the pressure spring 630, is held securely in place by the latches 610A. Obviously, it will be appreciated that any other configuration for holding, securing, and connecting the removable device is possible. For example, but not limited thereto, the concave space of the latching base 605 may be square, rectangular, hexagonal, or other shape. Also, instead of using a concave space for the latching base 605 , the removable device may be inserted into a slit in the yo-yo body 100 , which may function as another embodiment of the latching base 605 . In another configuration, the recessed space may be eliminated so that the detachable devices can be hooked and secured to the outer surface of either or both of the circular halves of the yo-yo body 100 . Any number of latches may be used and may be replaced by, but not limited to, pins, holes, grooves, screws, or other mechanisms capable of holding the removable device securely in place. Any number of latches may be configured with a pressure spring 630 , which may be replaced with any other device that facilitates engagement of the removable device. The connection pads 615 of the latching base 605 can be made of any material and shape that provides electrical signal and power connections to the removable device, for example, metal pins that fit into metal holes for electrical connections. However, it may not be limited thereto. Also, multiple connection pads may be used instead of a single connection pad 615 . Padding ring 620 may be made of any shape and material, as long as it provides cushioning and resistance, including non-annular forms such as padded surfaces. The latching base 605 may be implemented without any or all of the functions described in FIGS. 6A, 6B, and 6C as long as it is capable of securing and coupling the removable devices to the yo-yo body 100 .

7 shows a first possible embodiment of an optical display device 320 as a removable device implemented as a circular disk. A connection pad 710 for the removable device is disposed on the underside of the removable device and provides an electrical connection to the connection pad 615 of the latching base 605 . The two pads must be complementary to each other to provide an electrical connection. Any number of light emitting components 720 may be disposed on top of the removable device, such as LEDs, for example, in any desired location, size, color or any other characteristics of light emitting component 720 . can follow Other support components, such as, but not limited to, memory, switches, dimmers, impedance converters, power amplifiers, or any other components necessary for operation of optical display device 320 and light emitting component 720 . The elements may be disposed on the inside or on the body of the removable device, or disposed inside or on the yo-yo body 100 .

8 shows a second possible embodiment of an optical display device 320 , such as a removable device implemented as a round disk. Any number of lasers may be disposed on top of the removable device, including, for example, laser 810 . The following description of the laser 810 may also be applied to other lasers in this embodiment. The laser 810 may be attached to the upper side of the removable device by a holder 820 , placed on top of a piezoelectric actuator 830 , fixed, or glued. Therefore, in addition to turning the laser 810 on and off, the light beam of the laser 810 may be steered in a range of a certain angle, which is achieved by applying or not applying an electrical signal to the piezoelectric actuator 830 . The piezoelectric actuator 830 may be replaced by any mechanism, mechanical, electro-mechanical, electromagnetic, or other techniques that may be used to steer the light beam of the laser 810 in a range of angles. In addition, laser 810 may be disposed on top of or within the removable device, and steering of the light beam of laser 810 may be accomplished by moving the mirror or mirrors rather than moving laser 810 . Other supporting components may include, but are not limited to, memory, switch, dimmer, impedance converter, power amplifier, or optical display device 320 , laser 810 and piezoelectric actuator 830 required for operation. Any other components may be disposed inside or on the body of the removable device, or disposed inside or on top of the yo-yo body 100 . A second possible embodiment of such an optical display device 320 includes the implementation of a connection pad 710 of a detachable device not shown in FIG. 8 .

9 shows a possible embodiment of a sound reproducing device 325 as a removable device implemented as a circular disk. The implementation of the sound reproducing device 325 requires a membrane 910 and a mechanism (not shown in FIG. 9 ) for moving the membrane 910 according to an electrical signal. The sound reproducing device 325 may use a piezoelectric mechanism to move the membrane 910 , but other mechanisms may be used, such as, but not limited to, an electromagnetic or capacitive mechanism. Other supporting components, such as, but not limited to, memory, digital-to-analog converter, impedance converter, power amplifier, or any other component necessary for operation of sound reproduction device 325 and membrane 910 . They may be disposed on the inside or the top of the removable device, or on the inside or the top of the yo-yo body 100 . Such a possible embodiment of the sound reproduction device 325 includes the implementation of a connection pad 710 for a removable device not shown in FIG. 9 .

Using a removable device secured to the latching base 605 for the optical display device 320, or the sound reproduction device 325, has several advantages, for example, the same computerized device with a new removable device of a different type. It offers advantages such as the possibility to use the yo-yo 300, or the ability to make a better commercial trade-off between performance and price for removable devices. However, the latching base 605 may be used to secure another type of removable device, a device we refer to as the auxiliary device 330 . The assistive device 330 may be a disposable or semi-disposable, removable device, which may provide additional fun value to the computerized yo-yo 300 . 10 is a schematic diagram of a possible embodiment of an auxiliary device 330 , implemented as a removable device in the form of a circular disk. Various entertainment payloads 1010 are disposed on the upper side of the removable device. Recreational payloads 1010 may be small flame payloads, colored smoke payloads, colored powder payloads, or odor payloads. Recreational payloads 1010 may also be miniature capsules containing fun little objects, such as confectionery or accessories, or other payloads that provide a fun experience for the user of the computerized yo-yo 300 . The amusement payload 1010 may be a fireworks mechanism or other mechanism that ignites the fireworks, emits smoke, powder or odor, opens a capsule, or activates other recreational functions of the amusement payload 1010 . operating mechanisms may be used. Placing the entertainment payload 1010 on the upper side of the removable device may be installed or disposed as shown in FIG. 10, or may be constructed and dispensed in any pattern or shape on top or within the removable device. can be The assistive device 330 and other support components necessary for operation of the amusement payload 1010 may be disposed on or within the body of the removable device, or may be disposed on or within the yo-yo body 100 . . Such a possible embodiment of the auxiliary device 330 includes the implementation of a connection pad 710 of a removable device, not shown in FIG. 10 .

Obviously, many different types of removable devices are designed and secured to the latching base 605 for the purpose of enhancing the fun experience. One type of removable device may be any specific embodiment of an optical display device 320 , and may be any specific embodiment of a sound reproducing device 325 or an auxiliary device 330 . Because different types of removable devices may be secured to the latching base 605 , the computation and control device 305 may be configured to use an identification mechanism to identify the type of removable device secured to the latching base 605 . there is. The computation and control device 305 may then generate control signals appropriate to, and based on, the removable device of the identified type, and obtain the desired interesting experience. The identification device may be an analog device, for example a resistor with a different resistance for each type of removable device, wherein the resistance is measured by the computation and control device 305 and which type of removable device It can be identified whether is fixed to the latching base (605). The identification device may also be a digital device, for example a memory component that stores a different identification code for each different type of removable device, wherein the identification code is stored in the computation and control device 305 . is read, and it is possible to identify which type of removable device is secured to the latching base 605 . The identification device may be any device capable of being used by the computation and control device 305 to identify the type of removable device secured to the latching base 605 .

As a first example of using a removable device of the identified type, if the computing and control device 305 identifies the removable device as an optical display device 320, as shown in FIG. 7, and if the acceleration value When the computerized yo-yo 300 rotates at a speed R, for example, by measuring the number of revolutions per second, the calculation and control device 305 generates a control signal suitable for the optical display device 320 and emits light. It is possible to cause component 720 to flash at a rate of F _R = 4R, in flashes per second. As a second example of using a removable device of the identified type, if the computing and control device 305 identifies the removable device as a sound reproducing device 325, as shown in FIG. 9, and if the acceleration value When the computerized yo-yo 300 rotates at a speed R, for example, by measuring the number of revolutions per second, the calculation and control device 305 generates a control signal suitable for the sound reproducing device 325, Let 910 oscillate in beats per second, in beats of B _R = R.

Calculation and control device 305 generates, according to the detected type of removable device, a preset control signal to actuate the removable device that latches onto the latching base 605 , i.e. the specific type of removable device activates the latching base 605 . You can make each of them behave in a similar way every time it takes. However, it is also possible to operate certain types of removable devices in a variety of ways using many different settings of control signals to achieve other enjoyable experiences. Also, new types of removable devices may be used, and the computation and control device 305 may not have appropriate control signals for that type. Thus, it can be very useful if a new control signal can be loaded into the arithmetic and control unit 305, or can be generated by the arithmetic and control unit 305 using set parameters. The set parameters may be a complete control signal used by the computation and control device 305 to actuate the removable device, or may be used by the computation and control device 305 to generate a control signal for actuating the removable device. It can be any possible parameter. Accordingly, the communication device 345 may be configured to receive the setting parameter from the external device and transmit the received setting parameter. For example, but not limited thereto, the setting parameter may be a light pattern for the light display device 320 , sound data for the sound reproducing device 325 , or activation of the auxiliary device 330 . It may be a timing and condition for In another example, the setting parameter may relate to which user is currently playing with the computerized yo-yo 300 among several users.

The setting parameter may be any information received from an external device and used for both the extraction of the state parameter, the generation of the control signal, and the operation of the fun factor. For example, if the setting parameter assumes that the current user A is playing with the computerized yo-yo 300, and the acceleration value indicates the state in which the computerized yo-yo 300 is “wake up”, the extracted The state parameter and the generated control signal may control the optical display device 320 to flash red. On the other hand, if it is assumed that the setting parameter indicates that the current user B is playing with the computerized yo-yo 300, and the acceleration value indicates the state in which the computerized yo-yo 300 is “wake up,” the extracted state The parameter and the generated control signal may control the light display device 320 to flash yellow.

The external device may receive configuration parameters from any source, such as loading configuration parameters from any storage medium or the Internet, for example. In addition, when using a particular program or application on an external device or on another device, the user can also create some fun elements and new and interesting setting parameters for all types of removable devices, which in turn are compute and control devices. 305 , and used to trigger all the fun elements in the computerized yo-yo 300 in a new, exciting, fun, and exciting way.

In addition, the operation and control device 305 may use the communication device 345 for transmitting information on the yo-yo motion and state as an external device. The computation and control device 305 may use the acceleration values from the acceleration sensor device 315 (or together or separately with the tension values from the tensiometer device 350 ) and other information received from the fun factor. can be used to extract the status parameters, and the communication device 345 can be used to transmit the status parameters to an external device. For example, the status parameter may include identification of the removable device caught on the latching base 605 and information regarding the status of all devices or elements of the computerized yo-yo 300 . Accordingly, the state parameters are all parameters received by the arithmetic and control unit 305 , extracted by the arithmetic and control unit 305 , or generated by the arithmetic and control unit 305 . The external device may use these state parameters, which may provide additional fun experiences, such as but not limited to, display of the rotation speed of the yo-yo, which of the two users achieved the highest throwing force, or Who has played with the computerized yo-yo 300 the longest, or in the best way, etc., depending on the requirements of several possible games, or of the computerized yo-yo 300 that can enhance the fun experience for the user. Receive from the computation and control device 305 the use of motions, states and other information about conditions, and the like. In addition, the external device uses the information on the yo-yo motion, state, and condition, and receives from the calculation and control device 305 to calculate complex control parameters, which is more than the calculation capability of the calculation and control device 305 . It may require strong computational power, and then send the calculated complex control parameters back to the computation and control unit 305 to help generate control signals for the fun elements that provide the desired enjoyable experience. can

The optical display device 320 , the sound reproducing device 325 , and the auxiliary device 330 may generate an interesting experience for the user in response to the movement, state, and condition of the computerized yo-yo 300 . However, a more improved enjoyable experience can be achieved if the operation of the computerized yo-yo 300 is controlled, and can be adjusted. 11 is a schematic diagram of a computerized yo-yo 300 having a ball bearing 210 and an electric clutch arrangement 335 . Similar to the ball bearing type yo-yo as shown in FIG. 2 , the computerized yo-yo 300 of this embodiment includes a ball bearing 210 having an inner ring and an outer case attached to the yo-yo accelerator 130 . The electric clutch device 335 may be made of a piezoelectric clutch part 1105 that is attached to the yo-yo body 100 and may be disposed at the same distance from the yo-yo accelerator 130 as the outer case of the ball bearing 210 . The piezoelectric clutch component 1105 may expand or contract by applying (or releasing) an electrical signal. 11 shows four clutch parts 1105, two on each side of the yo-yo body 100, any number of clutch parts 1105 may be used in any configuration. Also, any other techniques may be used to implement clutch component 1105, including, but not limited to, magnetic, electromagnetic, or electro-mechanical techniques. Electrical clutch device 335 and other elements necessary for operation of clutch component 1105 include, for example, but not limited to, wiring, switches, power amplifiers, or other elements not shown in FIG. 11 . .

Clutch parts 1105 contract when an electrical signal is applied (or when no electrical signal is applied), eliminating any contact or friction between the clutch part 1105 and the outer case of the ball bearing 210 . can be configured to do this, which we will refer to as "unlock". The clutch component 1105 may also be configured to expand when no electrical signal is applied (or when an electrical signal is applied) and to create contact or friction between the outer case of the ball bearing 210 . , which we will call "locks". The contact and friction between the clutch part 1105 and the outer case of the ball bearing 210 generates a frictional force between the yo-yo body 100 and the outer case of the ball bearing 210 , and this force is the yo-yo body 100 . ) and will affect (decelerate) the relative motion between the outer case of the ball bearing 210 . This frictional force controls the relative motion between the yo-yo body 100 and the outer case of the ball bearing 210 , and thus also between the yo-yo body 100 and the string 110 . For example, if the clutch part 1105 is unlocked, the outer case of the ball bearing 210 rotates freely, which means that the movement of the computerized yo-yo 300 is a ball bearing, as shown in FIG. 2 . It means that it will be the same as the movement of the yo-yo. In another example, when the clutch component 1105 is locked, the outer case of the ball bearing 210 rotates together with the yo-yo body 100 , which indicates that the movement of the computerized yo-yo 300 is shown in FIG. The end of (110) means that it will be similar to the movement of a simple yo-yo firmly fixed to the yo-yo accelerator (130). However, an improved enjoyable experience may be achieved if the operation of the electric clutch device 335 is controlled by a control signal generated by the calculation and control device 305 . The control signal (electric clutch control signal) for the calculation and control device 305 is an acceleration value from the acceleration sensor device 315 (or together or separately with a tension value from the tensiometer device 350 ); It may be based on state parameters extracted from the operation and control unit 305, together with or separately from setting parameters received from an external device. For example, the electric clutch control signal may control the clutch component 1105 to remain locked when the user throws the computerized yo-yo 300 , and then the electric clutch control signal may be transmitted to the string 110 . When fully extended, the clutch component 1105 is rotated to unlock correctly, as indicated by the acceleration value from the accelerometer device 315 (or together or separately with the tension value from the tensiometer device 350 ). can be controlled This may have higher efficiency in the sense of increased rotational speed during the "sleep" state compared to the ball bearing yo-yo as shown in FIG. before the string 110 loses friction with the inner wall of the yo-yo body 100). In another example, the electric clutch control signal can control the clutch component 1105 in an unlocked state, the computerized yo-yo 300 is in a “sleep” state, and then an acceleration value from the accelerometer device 315 . (or together or separately with the tension value from the tensiometer device 350 ) may indicate that the user “wakes up” the yo-yo, which causes the computation and control device 305 to lock the clutch component 1105 . It is possible to generate an electric clutch control signal that controls the This allows the computerized yo-yo 300 to obtain a faster and easier “wake-up” compared to the “wake-up” of the ball-bearing yo-yo as shown in FIG. (need to actuate the string 110 to create sufficient friction between 110 and the inner wall of the yo-yo body 100). In another example, the computerized yo-yo 300 may be in a “sleep” state with the clutch component 1105 unlocked when the user executes a voice command to an external device, for example by pronouncing “up”. can The voice command can be recognized by an external device, which can transmit the appropriate setting parameters to the arithmetic and control device 305 via the communication device 345 , and then control to lock the clutch component 1105 . It may generate an electric clutch control signal and cause the computerized yo-yo 300 to start rolling upwards. Even if the yo-yo user does not want the electric clutch device 335 to assist or interfere with the movement of the computerized yo-yo 300 during the game, simply use the electric clutch device 335 to restart the game. ) can be used to assist in rewinding. In this example, string 110 is fully extended, but it is when computerized yo-yo 300 is no longer rotating, which may occur when the user loses control of the yo-yo and requires the user to start playing again. 110) needs to be rewound. In the case of the ball bearing type yo-yo shown in FIG. 2 , such rewinding is not simple, because the user must carefully manipulate the file 110 to generate initial friction for rewinding. In the case of a computerized yo-yo 300 with an electric clutch device 335 , the user can simply issue a voice command to an external device, for example “lock”. The voice command is recognized by an external device, and can transmit the appropriate setting parameters to the arithmetic and control device 305 via the communication device 345 , and then the electric clutch control to control the clutch component 1105 to lock. signal can be generated. Similarly, clutch component 1105 may be locked based on recognition of the first movement pattern. Once the clutch component 1105 is locked, the user can easily rewind the string 110 and, for example, issuing a second voice command, such as "unlock", will unlock the clutch component 1105. , then the user will be able to simply restart the yo-yo game. Similarly, clutch component 1105 may be unlocked based on recognition of the second movement pattern.

In addition, various levels of electric clutch control signals for the clutch component 1105 in the electric clutch device 335 can be used to generate various frictional forces between the clutch component 1105 and the outer case of the ball bearing 210 and , thus, it is possible to generate various frictional forces between the yo-yo body 100 and the outer case of the ball bearing 210 . The various frictional forces are for smooth control of the movement of the computerized yo-yo 300, for example, to gradually slow down the rotational speed of the computerized yo-yo 300, or when it "wakes up" and moves upward, The rotation speed of the yo-yo 300 may be controlled.

As described above, the width of the gap formed between the two round halves of the yo-yo body 100 is dependent on the need to reduce friction between the inner walls of the string 110 and the yo-yo body 100 during "slip" ( It's a trade-off between the need for wide spacing in this case) and the need for an easy "wake up" of the yo-yo (narrow spacing is needed in this case). 12 shows a computerized yo-yo 300, wherein an inner disk 1220 is additionally mounted to the outer case of the ball bearing 210, which helps to solve the above problem. 11 , this computerized yo-yo 300 also includes an electric clutch device 335 implemented by a clutch component 1105 . Obviously, if the clutch parts 1105 are unlocked, the user can throw the computerized yo-yo 300 as shown in FIG. 12, and when the string 110 is fully extended, as shown in FIG. The computerized yo-yo 300 as such will go into a “sleep” state. However, it would be impossible for the user to "wake up" the computerized yo-yo 300 as shown in FIG. 12 using the movement of the arm, hand, or finger, because the inner wall of the yo-yo body 100 is This is because, on the outside of the disk 1220 , it is impossible to create friction between the string 100 and the inner wall of the yo-yo body 100 . However, since the clutch component 1105 can be controlled by the computation and control device 305, locking the clutch components 1105 "wakes up" the computerized yo-yo 300 as shown in FIG. it will be possible In particular, for the computerized yo-yo 300 shown in FIG. 12 , the string 110 and inner disk 1220 do not move relative to each other during the “sleep” state, and thus the string 110 during the “sleep” state. ) and the inner wall of the yo-yo body 100 , it should be noted that friction is eliminated. This is illustrated in FIG. 12 , and a computerized yo-yo 300 with an inner disk 1220 is more efficient in that it can rotate longer during a “sleep” state. The electric clutch device 335 and other components necessary for the operation of the clutch parts 1105, such as, but not limited to, wiring, switches, power amplifiers and other elements are not shown in FIG. 12 .

When a yo-yo is in a “sleep” state and it is rotating fast enough for the user to perform a yo-yo “trick”, they are sequences of yo-yo movements that demonstrate the skill and agility of the user. However, when the rotational speed is slowed due to friction, the ability to perform the yo-yo tricks is reduced or eliminated. 13 shows a computerized yo-yo 300 comprising an electric clutch arrangement 335 and an electric motor arrangement 340 for creating an improved and enjoyable experience for the user. The electric motor arrangement 340 includes an electric motor 1310 mounted on an accelerator 130 similar to the ball bearing 210 in FIGS. 2 , 11 and 12 . The electric motor 1310 may include an inner part (corresponding to the inner ring of the ball bearing 210) that holds the electric coil and an outer case (corresponding to the outer case of the ball bearing 210) capable of holding the fixed magnet. can Assuming that the clutch component 1105 is unlocked, when no control signal is applied to the electric motor 1310 , the inner component rotates smoothly and, similarly to the ball bearing 210 , at least with respect to the outer case. will have friction of When a control signal is applied to the electric motor 1310 , a rotational force may be generated between the inner part and the outer case of the electric motor 1310 . Since the inner part of the electric motor 1310 is connected to the yo-yo accelerator 130 and in turn connected to the yo-yo body 100 , the generated rotational force is also applied between the outer case of the electric motor 1310 and the yo-yo body 100 . can If the yo-yo body 100 and the outer case of the electric motor 1310 do not initially rotate relative to each other, the rotational force may create rotational movement between them. If the yo-yo body 100 and the outer case of the electric motor 1310 are already rotating with respect to each other, the rotational force may increase or decrease this rotational speed, or the rotational force may even be in this rotational direction. can also be reversed. The string 110 may be connected to the outer case of the electric motor 1310 , which functions as the outer case of the ball bearing 210 shown in FIGS. 2 , 11 and 12 .

The electric clutch device 335 and the electric motor device 340 can be controlled by an arithmetic and control device 305 , which is an acceleration value from the accelerometer device 315 (or tension from the tensiometer device 350 ). on the basis of the state parameters extracted by the calculation and control device 305 or set parameters received from an external device (either together or individually), together or individually, on the basis of these, the electric clutch control signal And, it is possible to generate control signals (electric motor control signals) for the electric motor device 340 . For example, after the user throws the computerized yo-yo 300 shown in FIG. 13 , the clutch parts 1105 may be unlocked, and the electric motor device 340 moves the computerized yo-yo 300 downward. If so, it can act to increase its rotational speed. In another example, when the cord 110 is fully pulled, and the computerized yo-yo 300 shown in FIG. 13 is in a "sleep" state, the electric motor device 340 is controlled to maintain a constant rotational speed or , or activated, which allows the user to perform long sequences of yo-yo trick elements. In yet a further example, when the user completes the trick elements, it is generated by the friction force generated by the clutch component 1105 or by the electric motor 1310 the computerized yo-yo 300 shown in FIG. 13 . It is possible to "wake up" by the rotational force. In yet a further example, when the user performs the yo-yo trick elements, the user may issue a voice command to the external device, for example "fast", "slow", "up", "down", which An electric clutch control signal for controlling the electric clutch device 335 and the electric clutch control signal for recognizing by an external device and transmitting the setting parameters to the calculation and control device 305 through the communication device 345 and the electric motor device 340 It is possible to generate electric motor control signals to control the yo-yo together or separately, and to control the movement and state of the computerized yo-yo 300 according to the issued voice command. Electric clutch device 335 , electric motor device 340 , clutch parts 1105 , and other elements necessary for operation of electric motor 1310 , such as, but not limited to, wiring, switches, power amplifiers and other elements are not shown in FIG. 13 .

Other embodiments of the electric motor device 340 are possible, and they are such that, when an electric motor control signal is generated and applied to the electric motor device 340 , the electric motor device 340 causes the computerized yo-yo 300 to operate. It can be used if it functions to generate a torque that can be adjusted as required for movement. In addition, the electric motor device 340 may reverse its function and operate as a generator that charges the battery 310 .

Some features and other aspects of the present invention are individually presented with respect to FIGS.
