The disclosure relates to racket dampener devices and more particularly pertains to a new racket dampener device to obtain measurements of parameters relative to the player's performance while reducing vibration. The present invention includes both a multi-axis accelerometer to detect velocity as well as a gyroscope sensor to identify the parameter (forehand, backhand, serve, topspin, or flat) determined by linear acceleration and angular speeds of the dampener. The device may also include a Bluetooth transmitter to interact with an app to record these metrics, as well as a microcontroller to retrieve and process data from the accelerometer and gyroscope. The device may also include flash storage for onboard memory to store the data.
The prior art relates to racket dampener devices. Known devices typically serve to either dampen vibration or to serve as sensors. These devices lack both an accelerometer and a gyroscope, as well as the onboard memory and microcontroller to retrieve and process data. Known devices also lack a transceiver to wirelessly interact with an app to analyze the data collected.
An embodiment of the disclosure meets the needs presented above by generally comprising a dampener body having a body front side, a body back side, and a body perimeter. The body perimeter has a string channel configured to selectively engage a plurality of strings of a tennis racket. The dampener body absorbs vibration from the plurality of strings. An accelerometer is coupled within the dampener body. A vibration sensor is within the dampener body to detect when a ball is struck. A microcontroller is coupled within the dampener body and is in operational communication with the accelerometer. A memory chip is coupled within the dampener body and is in operational communication with the microcontroller. A transceiver is coupled within the dampener body. The transceiver is in operational communication with the microcontroller and configured to wirelessly communicate with an app on a smartphone or computer. A battery is coupled within the dampener body. The battery is in operational communication with the accelerometer, the microcontroller, and the transceiver. A charge port is coupled to the dampener body. The charge port is in operational communication with the battery.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A front perimeter 26 and a back perimeter 28 of the body front side and the body back side, respectively, may be chamfered. The body front side 14 and the body back side 16 may be circular. The dampener body 12 absorbs vibration from the plurality of strings 22.
An accelerometer 30 is coupled within the dampener body 12. The accelerometer 30 may be a three axis accelerometer 30. A microcontroller 31 is coupled within the dampener body 12 and is in operational communication with the accelerometer 30. A memory chip 33 is coupled within the dampener body 12 and is in operational communication with the microcontroller 31. The memory chip 33 may be flash storage.
A vibration sensor 66 is coupled within the dampener body 12. The vibration sensor 66 may be a piezoelectric sensor to detect vibration from striking a ball with the tennis racket 24. The vibration sensor 66 is operationally coupled to the microcontroller 31.
A transceiver 32 is coupled within the dampener body 12. The transceiver 32 is in operational communication with the microcontroller 31 and configured to wirelessly communicate with an app 34 on an extrinsic device 36 such as a smartphone, tablet, or computer. The transceiver 32 may be a wireless personal access network transmitter 32.
A battery 38 is coupled within the dampener body 12. The battery 38 is in operational communication with the accelerometer 30, the microcontroller 31, and the transceiver 32. A charge port 40 is coupled to the dampener body 12 and is in operational communication with the battery 38. The charge port 40 may extend through the body back side 16 and may receive universal serial bus charge cables.
A micro electrical mechanical system (MEMS) gyroscope 42 may be coupled within the dampener body 12 to measure rotational velocity of the tennis racket 24. The microcontroller 31 and the battery 38 are in operational communication with the MEMS gyroscope 42. The microcontroller 31 retrieves data from the accelerometer 30 and the MEMS gyroscope 42. The memory chip 33 stores the data collected from the accelerometer 30 and the MEMS gyroscope 42 via the microcontroller 31. The data from the MEMS gyroscope 42 identifies the shot type (forehand, backhand, serve, topspin, slice, or flat) and the data from the accelerometer 30 collects the hit velocity.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
