Description
- This application claims benefit of Provisional Application 60/583,876, entitled, Real-Time Measurements For Establishing Database of Sporting Apparatus Motion and Impact Parameters, filed Jun. 28, 2004, the entire contents of which is hereby incorporated by reference as if fully set forth herein, under 35 U.S.C. §119(e).
- The present invention relates generally to design of microelectronic systems and methods for providing real-time measurements of the motion and impact parameters of sporting equipment. More particularly, this invention is related to the use of micro-electro-mechanical system (MEMS) and magneto-resistive (MR) sensors and other microelectronics installed in sporting equipment such as a golf club, a hockey stick, a boxing glove, a tennis racket or a baseball bat to obtain real-time motion parameter measurements for analyzing a player's performance and for establishing diagnostic and training databases associated with a given sport.
- Conventional methods of measuring instantaneous position, orientation and velocity of sporting equipment such as golf clubs, hockey sticks and baseball bats are limited by the high-cost measurement equipment such as high speed cameras, laser array and photo detector array. Such high-cost equipments are typically limited to club design and club-fit in R&D laboratories and/or pro shops as in the golf industry, for example. Further, the unwieldy size of the measurement equipment prevents the use of such equipment during actual play of the sport.

FIG. 6 is a flow chart that illustrates a process flow for calculating parameters associated with a sporting implement at impact. - According to certain embodiments, an embedded sensing system is disposed in optimally selected locations of a sporting implement, such as a golf club, a baseball bat, a tennis racket, a hockey stick, a boxing glove, etc. The embedded system includes sensors that are small in size, accurate and capable of high speed measurements in order to reliably and dynamically measure, record and/or transmit the measurements to a processor. According to certain embodiments, the sporting implement includes sensors as described herein, an embedded micro controller or digital signal processor (DSP), a memory, an optional display and an embedded communication module. The sensors include one or more magneto-resistive (MR) magnetic field or compass sensors.
- According to certain embodiments, the MR sensors are used for dynamically measuring the three-dimensional magnetic vectors through the motion of the sporting apparatus, as in a golf swing or swing of a hockey stick, for example. For purposes of explanation, a golf club is used as an example. However, the embedded sensing system can be used for other sporting implements and can vary from implementation to implementation. The sporting implements include but are not limited to baseball bats, cricket bats, hockey sticks, tennis rackets, squash rackets, boxing gloves, etc. The sensors also include one or more MEMS accelerometer sensors for measuring the accelerations experienced by the sporting implement along various axes. Thus, the measurements made by the MR sensors and the MEMS sensors are used as input data into the micro controller or DSP for dynamically determining the movement profile, the launch angle, the face angle, and impact speed, and vibration characteristics of the sporting implement. Such parameters can be used for tracking and diagnosing the performance of the sportsman who is using the sporting implement. Such parameters can be sent through the communication module to a base station for further processing. The communication module can send data to the base station from the micro controller or DSP through wireless mechanisms such as infrared, Blue Tooth, WiFi, Zigbee or other Radio Frequency (RF) transmission mechanism. The communications module can also send data through RS232, SPI, USB or I2C and other wire based transmission mechanisms.
- The one or more embedded MR sensors are adapted for measuring relative changes of earth magnetic field in projection with respect to the multiple axes for dynamically recording the motion path, impact angle and launch angle of the sporting implement in real-time. In one embodiment, the sporting apparatus further includes one or more MEMS accelerometer sensors for sensing acceleration along multiple axes of a designated portion of the sporting implement for sensing impact velocity (when the designated portion impacts a ball, for example) and the tilt angle between the sporting implement shaft and the earth gravitational direction.

According to certain other embodiments, the accelerometer sensors and the magnetic sensors are disposed inside of the club shaft near the grip end of the shaft.
- The sensors, micro controllers or DSP, memory and communication modules can be separate semiconductor chips that are mounted on a printed circuit board (PCB) or connected by wires. Alternatively, the sensors, micro controllers or DSP, memory and communication modules can be integrated on a single chip that utilizes Application Specific Integrated Circuit Chip (ASIC) or Field Programmable Gate Arrays (FPGA) technologies that are capable of integrating several functions in a single chip.
- The memory in the embedded sensing system can be flash memory or DRAM for storing the programs used by the micro controller or DSP and for storing the measurement data from the sensors. The flash memory can also be used to transport the data from the sporting apparatus to the base station for further analysis.
- The base station is a separate unit that is not embedded in the sporting implement. The base station has a central processing unit (CPU) or a DSP, memory, display and communications modules to receive data transmitted by the embedded micro controller or DSP in the sporting implement for further processing and analysis.

-
- 1) angular difference of the sporting implement at moment of impact with the target object (examples of target objects are golf ball, hockey puck, baseball, etc.) compared with the address or static position.

The database can further include a data bank of data values of the above parameters associated with the performance of famous sportsman. Thus, a given player can analyze his performance based on comparisons with the data values associated with the performance of famous sportsman, or by comparing to another player of similar handicap, age, swing pattern, physical attributes, equipment used, etc.
- Types of Sensors
- The types of the sensors used in this design include a single-axis or multiple-axis magneto-resistive compass sensor (e.g. HMC1051 from Honeywell, Inc.) and a single-axis or multiple-axis MEMS accelerometer sensor (e.g. ADXL202 from Analog Devices).

FIG. 2 is a schematic that represents a golfer's swing of a golf club.Rod 101 represents the arms of the golfer, having the equivalent mechanical properties of his two arms, androd 102 represents the golf club, having the mechanical properties of the club used in the swing. The joint (103) betweenrod 101 androd 102 is a fully articulated joint. Further, joint 103 also represents the location of one set of sensors such assensors FIG. 1 . The system rotates about anorigin 100, which has a horizontal acceleration. The horizontal acceleration is along a direction in XH YH plane.Location 104 is the location of another set of sensors, such assensors FIG. 1 . From the above model, the club head velocity at the impact is composed of three components. The three components are: -
- (1) The linear velocity of the
rod 101 rotating around theorigin 100. This velocity component can be measured by an accelerometer sensor (23) installed at joint 103; - (2) The linear velocity of the
rod 102 rotating around the fully articulated joint 103. This velocity component can be measured by the centrifugal acceleration difference sensed by thesensor 23 at joint 103 (A23) andsensor 28 at 104 (A28) and the known distance between 103 and 104 (D(103-104)) and the distance between joint 103 and the club head or the club length (D103); and - (3) The velocity generated by the horizontal acceleration of the
origin 100. This component is small and can be added base on the experimental results or simply neglected.
Shaft Rotation Acceleration Calculation Method
- (1) The linear velocity of the
- In a typical golf swing, the shaft can have a rotation around
centerline 30 as shown inFIG. 1 . Such a rotation is for purposes of modeling the waggle of golfer's wrist and hand. This rotation acceleration can be measured by the acceleration difference of sensor 21 (A21) and sensor 22 (A22). This rotation acceleration is used in following roll angle calculation. - The Club Roll Angle (θ) Calculation Method
- The roll angle (θ) is required for the launch angle (θ) and face angle (θ) calculation. The roll angle is defined as the angle between the club shaft and the gravitational force.
FIG. 3 is a schematic that illustrates the roll angle. InFIG. 3 ,orthogonal coordinates X H 108,Y H 109,Z H 110 represent the earth coordinate system, and (XH, YH) plane is the horizontal plane.Location 104 is the location of sensors as previously described with reference toFIG. 2 andFIG. 1 .Angle 106 is the roll angle (θ),axis 105 is in the direction of the earth's gravitational force.Axis 107 is an axis perpendicular to the longitudinal axis of the club shaft and parallel to the axis of theaccelerometer sensor 21 installed atlocation 103 ofFIG. 1 . The roll angle is the angle between the horizontal plane andaxis 107. The heading direction is in the direction ofX H 108 in the earth coordinate system. The acceleration component A21 can be measured bysensor 21. Thus, the roll angle (θ) can be calculated as arccosine (A21/g), where g is earth gravity. - The shaft rotation will affect the roll angle measurement and calculation. Therefore, instead of using A21 to calculate the roll angle, (A21-A22) should be used.
- The Static Club Launch (Pitch) Angle (φ) Calculation Method
- Before a golf swing, the golfer usually has a posture and has the club close to the ball in an “address” position. At the address position, a static launch angle or pitch angle (φ) can be measured by
sensor 24 and calculated as arccosine (A24/g), where A24 is the acceleration measured bysensor 24 and g is earth's gravity. - The Earth Magnetic Field Vector in Earth Gravity Direction Calculation Method
- If the
orthogonal coordinates X H 108,Y H 109,Z H 110 represent the earth coordinate system, and (XH, YH) plane is the horizontal plane, then ZH axis is the direction of the earth's gravity.FIG. 4 illustrates the magnetic field vector (MxH 113, MyH 114, MzH 115) in the horizontal plane relative to the earth coordinate system.Angle 116 is the face angle.FIG. 5 illustrates the coordinate system of the earth magnetic field vector (Mx117, My118, Mz119) in the shaft coordinate system (i.e., embedded sensor coordinate system) relative to the earth coordinatesystem X H 108,Y H 109,Z H 110.Angle 120 is the launch angle, andangle 106 is the roll angle.Mearth 111 is the earth's magnetic field. The earth's magnetic field can be expressed as M (MxH, MyH, MzH), where MzH is the same as Mg and M2=MxH 2+MyH 2+Mg2. Because the angle between the earth's magnetic field and the earth's gravity does not change at any given location, Mg will be constant at the given location. Therefore, Mg will not change with the club motion. - At the address position when the golf shaft is static, the following parameters can be measured from the sensors as previously described:
-
- shaft roll angle (θ0) from
sensor 21; - shaft pitch angle (φ0) from
sensor 24; - earth magnetic vector along X (10) direction Mx0 from
sensor 27; - earth magnetic field vector along Y (11) direction My0 from
sensor 26; and - earth magnetic field vector along Z (12) direction Mz0 from
sensor 25.
- shaft roll angle (θ0) from
- Mx0, My0 and Mz0 can be transformed back to the horizontal plane (XH, YH) by applying the rotational equations shown below:
Mx H =Mx 0*cos(φ0)+My 0*sin (φ0)*sin(φ0)−Mz 0*cos(θ0)*sin(φ0)
My H =My 0*cos(θ0)+Mz 0*sin(θ0)
Azimuth(face angle(α0))=arc Tan(My H /MX H)
Therefore, M g 2 =M 2 −Mx H 2 −My H 2
The Dynamic Launch Angle (φ) and Face Angle (α) Calculation Method - During a golf swing at impact, the following parameters can be measured by sensors:
-
- shaft roll angle (θ) from sensor;
- earth magnetic vector along X (10) direction Mx from
sensor 27; - earth magnetic field vector along Y (11) direction My from
sensor 26; and - earth magnetic field vector along Z (12) direction Mz from
sensor 25.
- Unlike the static situation, the pitch angle can not be measured by the
accelerometer sensor 24 due to the interference of the shaft acceleration along the X (10) direction in the swing. - By using the same rotational equations shown below, Mx, My and Mz can still be transformed back to the horizontal plan (XH, YH),
Mx H =Mx*cos(φ)+My*sin(θ)*sin(φ)−Mz*cos(θ)*sin(φ)
My H =My*cos(θ)+Mz*sin(θ)
Azimuth(face angle(α))=arc Tan(My H /Mx H)
M g 2 =M 2 −Mx H 2 −My H 2
Therefore,
Azimuth(face angle(α))=arc Tan((My H/root square(M 2 −M g 2 −My H)2)=arc Tan(((My*cos(θ)+Mz*sin(θ))/root square(M 2 −M g 2−(My*cos(θ)+Mz*sin(θ))2)
Launch angle(φ)=arc sine((−B+/−root square(B 2−4AC))/2A)
Where A=Mx2+((Mz*cos (θ)−My*sin (θ))2, B=2*(Mz*cos (θ)−My*sin (θ))*root square (M2−Mg 2−(My*cos (θ)+Mz*sin (θ))2), and C=M2−Mg 2−Mx2−(My*cos (θ)+Mz*sin (θ))2 - The three axis MR sensor orientation on the PCB board can be varied as long as the angle between one of its axes and the shaft longitudinal direction is known. A fix angle rotation operation can bring the coordinates back to the (Mx, My, Mz) coordinates discussed above.

FIG. 6 is a flow chart that illustrates a process flow for calculating parameters associated with a sporting implement at impact. Atblock 601, the sensing and DSP system (embedded and non-embedded) are initialized. Atblock 602, some data is input into the base station (such as a PDA) and the sensors are calibrated atblock 604. Examples of data that is input into the base station are arm length of the player, and height of the player. The sensors can be calibrated based on a table lookup automatically performed by the base station, or the base station can be equipped to calculate the calibration. In the case of a table look-up, the table of data can be resident on the base station or can be downloaded over-the-air onto the base station from an appropriate server. The sensors need to be calibrated based on the geographic location where the game is played. Atblock 606, static position (address position, for example) measurements are taken. Atblock 608, the sporting implement is swung and impact of the sporting implement against a target object (such as a golf ball, shuttle cock, etc.) takes pace. Atblock 610, the impact velocity, the roll angle, the face angle, the launch angle and the hitting zone are calculated. Atblock 612 the swing path is calculated. Atblock 614, the measurements and results are stored in the base station such as a PDA. Atblock 616, the results are displayed on a display device such as the PDA and the results and measurement can be optionally transmitted (uploaded) to a relational database. The relational database can be web-based. Atblock 618, the process flow is complete and the system is reset. - In the foregoing specification, embodiments of the invention have been described with reference to numerous specific details that may vary from implementation to implementation. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
