The data collecting mouthpiece 100 (hereinafter invention) is an exercise device. The invention 100 is adapted for use with a user 200. The invention 100 inserts in the mouth 210 of the user 200. A biting motion between the superior dentition 201 and the inferior dentition 202 of the mouth 210 creates a compressive force 143 that exercises the muscles around the jaw, tongue 203 and mouth 210 of the user 200.
The invention 100 comprises an enhanced mouthpiece 101, a data sensor 102, and a personal data device 103. The enhanced mouthpiece 101 comprises the original mouthpiece 111 described by non-provisional application U.S. patent application Ser. No. 15/4470983 which is incorporated into this disclosure in its entirety. The enhanced mouthpiece 101 is substantially identical in construction to the original mouthpiece 111. The enhancements made by the present disclosure to the original mouthpiece 111 to form the enhanced mouth 210 piece comprises the installation of the data sensor 102 into the enhanced mouthpiece 101. The data sensor 102 collects data regarding the bite force, the number of bites and the duration of each bite. The data sensor 102 wirelessly transfers the collected data to a personal data device 103.
The personal data device 103 is a programmable electrical device. The personal data device 103 further comprises an application 131. The personal data device 103 provides data management and communication services through one or more functions referred to as the application 131. The application 131 is a set of logical operating instructions that are performed by the personal data device 103. The addition of an application 131 will provide increased functionality for the personal data device 103. This disclosure assumes that an application 131 exists for the purpose of collecting and displaying the data collected by the invention 100. Methods to design and implement an application 131 on a personal data device 103 are well known and documented in the electrical arts.
The enhanced mouthpiece 101 is a mechanical structure. The enhanced mouthpiece 101 inserts in the mouth 210 of the user 200 between the superior dentition 201 and the inferior dentition 202. The enhanced mouthpiece 101 receives a compressive force 143 generated by the biting motion of the superior dentition 201 and the inferior dentition 202 during the exercise process. The enhanced mouthpiece 101 comprises an original mouthpiece 111 and a sensor cavity 112.

The original mouthpiece 111 is the same as the mouthpiece described in the prior disclosure. The original mouthpiece 111 is described in greater detail elsewhere in this disclosure. The original mouthpiece 111 further comprises a cavity 141 and a removable insert 142. The original mouthpiece 111 receives the compressive force 143. The compressive force 143 refers to a force that is applied to the enhanced mouthpiece 101 when the superior dentition 201 and the inferior dentition 202 perform a biting motion.
The cavity 141 is a negative space that is formed through the center of the original mouthpiece 111. The cavity 141 is the same as the cavity in the mouthpiece that is described in the prior disclosure. The cavity 141 is described in greater detail elsewhere in this disclosure.

The data sensor 102 is an electrical circuit that collects information about the compressive force 143 during the exercise process. The data sensor 102 captures the measure of the compressive force 143 of each bite. The data sensor 102 captures the measure of the number and duration of bites applied to the enhanced mouthpiece 101.

Depending on the specific design and the selected components, the logic module 121 can be a separate component within the data sensor 102 or the functions of the logic module 121 can be incorporated into another component within the data sensor 102. The communication module 122 is a wireless electronic communication device that allows the logic module 121 to wirelessly communicate with a personal data device 103. Specifically, the communication module 122 establishes a wireless communication link 151 between the data sensor 102 and the personal data device 103. In the first potential embodiment of the disclosure, the communication module 122 supports a Bluetooth™ protocol.
The piezoelectric sensor 123 is a disk-shaped plate. The piezoelectric sensor 123 has a non-Euclidean disk structure that allows the piezoelectric sensor 123 to fit within the sensor cavity 112 of the enhanced mouthpiece 101. The logic module 121, the communication module 122, and the power system 124 mount on the face of the piezoelectric sensor 123. The piezoelectric sensor 123 is formed from a piezoelectric material that generates a measurable voltage when the piezoelectric sensor 123 is subjected to a strain such as the compressive force 143.
The application of the compressive force 143 to the piezoelectric sensor 123 results in a change in voltage across the surface of the piezoelectric sensor 123 that is a positive function of the compressive force 143. The logic module 121 monitors the voltage across the face of the piezoelectric sensor 123 such that the logic module 121 will measure the: a) compressive force 143 applied to the piezoelectric sensor 123; b) the duration of each bite that generates the compressive force 143; and, c) the number of bites made by the user 200.

The charging port 163 is an electrical circuit that reverses the polarity of the rechargeable battery 161 and provides the energy necessary to reverse the chemical processes that the rechargeable battery 161 initially used to generate the electrical energy. This reversal of the chemical process creates a chemical potential energy that will later be used by the rechargeable battery 161 to generate electricity.
The charging port 163 forms an electrical connection to an external power source 164 using a charging plug 165. The charging plug 165 forms a detachable electrical connection with the charging port 163. The charging port 163 receives electrical energy from the external power source 164 through the charging plug 165. The diode 162 is an electrical device that allows current to flow in only one direction. The diode 162 installs between the rechargeable battery 161 and the charging port 163 such that electricity will not flow from the first positive terminal 171 of the rechargeable battery 161 into the second positive terminal 172 of the external power source 164. In the first potential embodiment of the disclosure, the external power source 164 and the charging port 163 are compatible with USB power requirements.
