DESC:TITLE OF THE INVENTION
“WEARABLE FITNESS DEVICE”

FIELD OF THE INVENTION
[0001] The present disclosure relates to the field of fitness devices. More particularly, it pertains to a wearable fitness device that, in addition to tracking the fitness activity of a user, provides data insights on targeted muscles for fitness training. The device is relevant to several areas including digital well-being, health monitoring, fitness monitoring, athletic coaching, and muscle and strength training.

BACKGROUND OF THE INVENTION
[0002] Wearable health and fitness tracking devices also known as activity trackers, are intended to capture and track details of a user's physiological parameters, rest periods, sleep cycles, and physical activities throughout the day. Such activity trackers generally include various sensors such as a heart rate monitor, a pedometer, an oximeter, an accelerometer, a gyroscope, a temperature sensor, and the like, which are embedded in a wearable form (maybe a wristwatch or a wristband), and provide measurements of the bodily functions and the physical activities of a user. Most wearable trackers continuously sense the body’s movements using a 3-axis accelerometer, based on arm movement, which may result in high overestimation.

[0003] The data is recorded all the time while it is worn and powered up, which enables the tracker to trace if the individual is walking forward, running fast, or even standing still. For example, the data from all the sensors can be part of an algorithm that ultimately displays the number of steps. Depending on the type of wearable device, such as a watch, a bike ride could also be counted as a step. Conversely, keeping your hands steady in one place can underestimate your steps. If one wears two tracker devices, he/she will most likely get two different results. Even if both the trackers have the same data, the interpretations of their data analytics could be vastly different.

[0004] In such scenarios, different or inappropriate results make the data inaccurate and unreliable. It raises doubts and concerns about the efficiency and accuracy of the activity trackers in detecting these parameters. Sportspersons and athletes, who are training to accomplish their fitness objectives, require perfect information and data about how their workouts are progressing. Such unreliable and inaccurate results can greatly affect their progress and jeopardize their overall objective.

[0005] Further, conventional fitness trackers are restricted to tracking only a few selected parameters, such as heart rate, sleep monitoring, SpO2, and single-lead ECG. For example, a US Patent US4966154 discloses a multiple-parameter monitoring system for ambulatory human patients. The system utilizes a separate harness to be removably worn by each patient and adapted to engage the chest of the patient. The harness incorporates a first ECG data sensing device engaging the patient to produce first and second analog voltages having variable magnitudes which are measurements of body MCL1 and MCL6 data respectively. A second respiratory amplitude sensing device produces a first analog signal having a variable magnitude which indicates the measurement of the respiratory amplitude of the patient and a third temperature sensing device engages the patient’s body to produce a second analog signal for measuring the temperature of the patient.

[0006] Conventional fitness devices cannot distinguish between aerobic and anaerobic training, reducing their reliability for athletes. Despite being popular in smartwatches and ring form factors, they struggle with accurate metrics like step count and heart rate. They gather redundant data without validation, offer limited insights, and are restricted from measuring multiple parameters & hindering precise fitness analysis.

[0007] Thus, there is an unmet need to provide a wearable fitness device that is accurate, reliable, and capable of discerning the differences between various physical training modes including aerobic exercises and anaerobic exercises in all working conditions and requirements. There is a further need for a wearable fitness device that provides critical fitness insights with cross-validation and accurate analytics.

OBJECTIVE OF THE INVENTION
[0008] The primary objective of the present invention is to provide a wearable fitness-tracking device that, in addition to tracking fitness activity, tracks targeted muscles for fitness training accurately and reliably.

[0009] Another objective of the present invention is to provide a wearable fitness-tracking device that can discern the difference between endurance training (aerobic exercises) and resistance training (anaerobic exercises) during workouts.

[0010] Another objective of the present invention is to provide a wearable fitness-tracking device that can provide accurate critical fitness insights with cross-validation based on the health and activity data collected.

[0011] Another objective of the present invention is to provide a wearable fitness-tracking device that has a form factor that keeps the sensors/electrodes in proximity to the clinically accepted positions for the parameters being measured.

[0012] Another objective of the present invention is to provide a wearable fitness-tracking device that has a smaller footprint and profile to avoid any hindrance to the user.

[0013] Another objective of the present invention is to provide a wearable fitness-tracking device with operations and functions that can be customized by the user.

The use of “a” and “an” does not limit the meaning to a single feature unless such a limit is specifically stated. The article “the” preceding singular or plural nouns or noun phrases denotes a particular specified feature or particular specified features and may have a singular or plural connotation depending upon the context in which it is used. The adjective “any” means one, some, or all indiscriminately of whatever quantity.

[0030] The present invention relates to a wearable fitness device that continuously tracks physical activity and also targets the monitoring of specific muscle groups of the user and provides long-term health data insights that the user can use to achieve their fitness and athletic goals.

[0031] The wearable fitness device includes a plurality of sensors, a control and communication module, extension means, and a power source all contained within the construction of a harness formed by a plurality of straps. These elements function together to detect the user's physiological parameters directly from the upper torso region but are not limited thereto, accurately and reliably. This approach ensures the precision and dependability of the acquired measurements. The sensors are positioned appropriately at designated areas on the body, ensuring the best possible results from each sensor.

[0032] Figures 1A and 1B illustrate different views of wearable fitness devices, including a front and rear view. The wearable fitness device comprises a plurality of straps (10, 12, 14) attached to form the harness (16). The straps (10, 12, and 14) are arranged in a manner that at least two of the straps (10, 12) are attached in a cross-orientation forming a junction (18), and at least one strap (14) is attached horizontally to join a lower end of the crossed straps (10, 12) (as illustrated in Figures 1A and 1 B). The harness (16) formed with the arrangement of the straps (10, 12, 14) is designed to be worn on an upper-torso region (20) of a user’s body to clasp the shoulders and upper abdomen of the user. The harness (16) is made of comfortable high GSM non-woven fabric of natural and/or synthetic fibers having elastic and non-elastic components.

[0033] In an embodiment, the high GSM non-woven fabric may be a blend of cotton, polyester, and other elastomer. In a further embodiment, the harness (16) has a form factor of a torso-worn brace/harness which is adapted to confirm the bodily contours of the user irrespective of the user’s body type. The form factor, here refers to the physical design or arrangement of the harness (16), including size, shape, and the materials used, which are tailored to ensure a comfortable & snug fit that supports the intended functionalities of the wearable fitness device.

[0034] The form factor of the harness (16) ensures consistent contact of each of the straps (10, 12, and 14) of the harness (16) with the user’s skin/body while ensuring breathability and comfort for prolonged use. The harness (16) may easily be worn with conventional and/or athletic clothing without any significant hindrance. In an embodiment, the harness (16) may contain a detachable elastic retainer (not shown here) to fit the body contours of the user irrespective of their body type and shape.

[0035] Furthermore, the harness (16) may include a plurality of tubular channels (not shown here), embedded in each of the straps (10, 12, and 14) and elongate along the length of the straps (10, 12, and 14). The tubular channels facilitate the passage of various insulated wirings running within the straps (10, 12, and 14) and provide support to each of the insulated wirings inside the straps (10, 12, and 14) thereby preventing breakage of the wirings. In an embodiment, the tubular channels may be of a hollow cylindrical shape, hollow rectangular shape, and the like.

[0036] The insulated wirings facilitate data transmission and power supply between the control unit (22), plurality of sensors (24, 26, 28, 30, 32), and other components, for the detection and analysis of various physiological parameters of the user's body. The physiological parameters include blood oxygen saturation level, heart rate, Electrocardiogram and other Cardiovascular Performance factors, muscle activity, and respiratory parameters. The above-disclosed parameters are measured by the plurality of sensors including PPG (photoplethysmography) sensors (24), Inductance Plethysmography sensors (26), electrocardiography sensors (28 for single-Lead; positions not indicated for 6-Lead embodiment), Electromyography sensors (30), and Inertial Measurement sensors (32). These sensors are integrated into/on the straps (10, 12, and 14) and positioned at specific areas of the user’s body, to detect real-time parameters and provide the results more reliably and accurately.

[0037] The plurality of sensors (24, 26, 28, 30, and 32) may be detachably mounted on the plurality of straps (10, 12, and 14) via the extension means for detecting the real-time physiological parameters of different body parts of the user. The extension means disclosed here, maybe cables, flexible wirings, or any other means of connection that allow the extension/addition of sensors/electrodes without disturbing the connection of a plurality of sensors (24, 26, 28, 30, 32) with the control unit (22), for the detection of various physiological parameters.

[0038] The PPG (photoplethysmography) sensor (24) is integrated into at least one of the straps (12) which are positioned in contact with the chest area over the Sternum of the user’s body to measure blood oxygen saturation percentage and heart rate. The PPG sensor (24) consists of an emitter-detector pair, an Analog-Front-End, and other auxiliary components, which are enclosed in at least one strap. The emitter-detector pair in the wearable fitness device is positioned in such a way that it allows light to pass from the sensor into the user's body and back again. This configuration enables the detection of blood oxygen saturation percentage using the principle of Reflectance Plethysmography.

[0039] The Reflectance Plethysmography works by emitting light into the skin, where some of the light is absorbed by tissues and blood. The detector then measures the light that is reflected. The amount of reflected light varies with changes in blood volume, such as those that occur with each heartbeat. By analyzing these variations, the PPG sensor (24) then precisely senses the user's blood oxygen saturation percentage, providing valuable health information during physical activities or at rest. Further, the heart rate is measured by measuring the periodicity of change in the illumination levels at the photodetector in the PPG sensor (24).

[0040] The harness (16) includes one or more Inductance Plethysmography sensor(s)/transducers (26), embedded in one or more straps (14) positioned in proximity to the diaphragm below the chest area of the user’s body (as illustrated in Figures 1A and 1B). The Inductance Plethysmography sensors (26) are configured to determine the respiratory parameters of the user. The respiratory parameters include respiratory rate, breath-by-breath variability, tidal volume, breath hold time, asynchronous breathing pattern, and total respiratory effort. The Inductance Plethysmography sensor(s) (26) comprises an elastic band, fitted inside the strap (14) that is placed over the lower chest/abdomen. The band contracts/expands to detect the changes in the body circumference during respiratory movements.

[0041] The detected respiratory movements are converted to electrical signals by the Inductance Plethysmography sensor (26) and enable real-time monitoring and analysis of respiratory patterns during activity. This in turn allows the user to optimize their breathing techniques and improve respiratory efficiency. In an embodiment, an Analog-Front-End, filter circuitry may be employed in the Inductance Plethysmography sensor(s) (26) to ensure reliable pickup of the raw signal from the sensor.

[0042] Further, one or more electrocardiography sensor(s) (28) are integrated into one or more straps (10) kept in contact with the chest area towards the left of the sternum of the user. The electrocardiography sensor(s) (28) comprises at least a pair of electrodes placed directly over the chest near the heart. In an embodiment, the electrodes may be provided with an amplifier, an Analog-to-Digital converter, and filter circuitry to extract cardiac activity and reject unnecessary noise. The ECG electrodes along with their auxiliary components are controlled by a dedicated Analog-Front-End that can take ECG readings of the user at predetermined intervals. The electrocardiography sensor(s) (28) also helps in monitoring Cardiovascular Performance Parameters which may include climb rate, endurance monitoring, descent rate, resting rate, and HR-Max.

[0043] In one embodiment, the ECG electrodes in the Electrocardiography sensor(s) (28) may be clip-on type electrodes that are not necessarily integrated with the straps (10, 12, 14) of the harness (16) and are required to be in firm contact with the skin to ensure proper signal pickup from the user’s body.

[0044] In another embodiment, the ECG electrodes are positioned such that at least a Single-Lead ECG recording is obtained from the user’s body, concerning the above-mentioned Cardiovascular Performance Parameters.

[0045] In an alternate embodiment, the ECG electrodes are positioned such that a 6-Lead ECG recording is obtained from the user’s body, concerning the above-mentioned Cardiovascular Performance Parameters.

[0046] The harness is further installed with one or more electromyography sensors (30) that are embedded in one or more straps (10). The electromyography sensor(s) (30) engages in contact with the trapezius muscle below the shoulders and with the Erector spinae muscle of the spinal cord, to determine the voluntary muscle activity of the user’s body. The electromyography sensor (30) comprises at least a pair of electrodes strategically placed over a specific muscle group on the torso region (20) of the user’s body. The EMG electrodes sense the electrical signals from the corresponding muscles and transmit the picked-up signals to a dedicated controller equipped with an Analog-to-Digital converter.

[0047] In an embodiment, the controller may contain dedicated hardware filter circuits to properly streamline the necessary signals and remove the noise. Alternatively, the ECG AFE may also be used to pick up the muscle signals, provided both are operated with independent filter circuits.

[0048] In another embodiment, the Electromyography sensors (30) may also consist of clip-on type electrodes that are slightly larger than the electrodes of an Electrocardiography sensor (28). The EMG electrodes are placed on the back and the shoulders to allow measurement of muscle activity in a large and diverse muscle group including the erector spinae, latissimus dorsi, and trapezius. These muscles play a significant role in activities like posture control, core stability, and upper body movements. By monitoring muscle activity in this area, a comprehensive assessment of overall muscle movement and performance can be obtained via the electromyography sensor (28). The device also provides insights into muscle engagement and supports exertion analysis during various exercises and activities. The placement of the electrodes of the electromyography sensor (30) is not limited to the torso region (20) of the user’s body.

[0049] In another embodiment, the device may contain peripheral modules with EMG electrodes that may be used in the limbs to assess the muscle groups including but not limited to the ‘biceps’, ‘triceps’, ‘flexor carpi’, and ‘quadriceps’. The EMG data may be used for exertion analysis and strength training by the user.

[0050] Further, the harness includes one or more Inertial Measurement sensors (32) configured in one or more of the straps (10, 12) to be in contact with a clavicle area of shoulders near the rib cage frame of the user’s body. The inertial measurement unit detects the motion, position, and orientation of the user along with movements including arm swings, shoulder rotations, and upper body gestures. The Inertial Measurement sensor (32) includes a “Micro-Electro-Mechanical Sensor” unit, which tracks motion, orientation, and heading as a component function of the three Cartesian coordinate axes. More specifically, the Inertial Measurement sensor (32) measures the motion of the user as a function of time and acceleration (both positive and negative) splits across its constituent values resolved as acceleration values along the three primary Cartesian axes.

[0051] In another embodiment, the device includes an ECG measurement unit having one or more electrodes positioned appropriately and capable of acquiring cardiac electrical activity of the wearer that is equivalent to 6-Lead ECG reading.

[0052] The Inertial Measurement sensor(s) (32) are placed strategically within the straps (10, 12). The strategic placement results in accurate detection of the user’s position and orientation. Further, the Inertial Measurement sensor(s) (32) adjusts the readings accordingly via an embedded internal reference plane virtualization by using the orientation of gravity as the absolute standard. The positioning in the shoulders and back facilitates the capture of a wide range of movements including arm swings, shoulder rotations, and upper body gestures directly. The shoulders provide a relatively stable and consistent location for sensor placement thus maintaining the accuracy and reliability of the data.

[0053] After the detection of each physiological parameter of the user’s body, the plurality of sensors (24, 26, 28, 30, 32) transmit their respective signals of the detected parameters to the control unit (22), integrated within the junction (18) of the straps (10,14), in the form of digital signals output. The control unit (22) includes a microcontroller (34) and non-volatile storage within which one or more predefined instructions are stored when executed allowing the microcontroller (34) to handle and control the communication with the plurality of sensors (24, 26, 28, 30, 32).

[0054] In an embodiment, the control unit (22) can be embedded within the harness (16), with a high degree of ingress resistance to liquids and dust particles by providing moisture and air-tight enclosure for the electronic components of the device and providing replaceability and easy access to the control unit (22).

[0055] Figure 2 illustrates a flow diagram explaining the functioning of the control unit (22) of the wearable fitness device. The flow diagram illustrates how the control unit (22) processes and transmits the output data received from the plurality of sensors (24, 26, 28, 30, and 32) to the user device, thereby facilitating communication between the user device and the wearable fitness device.

[0056] Once the control unit receives the output from the plurality of sensors (24, 26, 28, 30, and 32), the control unit (22) uses the microcontroller (34) to process and analyze the received output signals. The microcontroller (34) while analyzing the received data signals acquires the raw data from the plurality of sensors (24, 26, 28, 30, and 32) and may perform necessary data acquisition processes via a dedicated filter circuitry (36) and/or digital filters.

[0057] The filter circuitry (36) is electrically paired with multiple controllers/amplifiers (38) each specifically coupled with a specific sensor of the plurality of sensors (24, 26, 28, 30, and 32) for the data acquisition process. In an embodiment, the control unit processes the data locally or remotely.

[0058] After acquiring the data from the plurality of sensors (24, 26, 28, 30, and 32), the amplifiers/controllers (38), for processes like, filtering, segregation, and so on, initiate the processing of the raw data. Individual data is either obtained by filtering digital signal input or the isolation of one or more independent frequencies from an analog signal. This may be achieved either by dedicated filter circuitry (36) hardware or by using digital filter algorithms.

[0059] The filtering processes also filter out artifacts and signal noise to increase the signal-to-noise ratio. The filtration and segregation processes of the raw data are collectively known as data conditioning. On completion of the data conditioning process, the control unit (22) transmits the conditioned data to the user device via the communication module (40) to allow the user to remotely access the processed data.

[0060] The communication (40) module helps the user in real-time tracking based on the electrical activity of voluntary muscles and motion telemetry to monitor both aerobic and anaerobic exercises and to provide accurate fitness information to the user. The processed data received by the user is further used for specific training and performance enhancement purposes by the user. Also, it allows the user to remotely customize the operations and functions of the wearable fitness device, for example, via an application running on the user device, thus making the wearable fitness device re-configurable and versatile.

[0061] In a further embodiment, the wearable fitness device is developed in a manner to have a small footprint and profile, ensuring comfort to the user wearing the wearable fitness device and avoiding any hindrance in the movements of the user during usage.

[0062] In a further embodiment, the wearable fitness device does not include any hard points nor hinder or disrupt the posture during usage and provides an ease of motion, i.e., full range of motion, and avoids any resistance to the user’s movements.

[0063] Further, the wearable fitness device is configured with a power source (42) (as illustrated in Figure 2) which is preferably a rechargeable battery (42) utilized to supply electrical power to the plurality of sensors (24, 26, 28, 30, and 32), the control unit (22), the communication module (40), and other auxiliary components of the wearable fitness device. The rechargeable battery (42) is a type of lithium chemistry battery packed in a cylindrical/pouch form factor and configured in a series, parallel, or a mixture of both to deliver the desired voltage, capacity, or power density.

[0064] In a further embodiment, the battery management system may contain necessary safety standards while charging/during use for example under/over current/voltage/temperature protection to ensure user safety.

[0065] In another embodiment, the power source (42) may be installed with one or more onboard batteries or removable batteries which may be placed close to the control unit (22) to mitigate power transmission losses.

[0066] Furthermore, the wearable fitness device includes a power regulation module which is a combination of a Battery Management System and independent battery(s). The battery management system handles charging, discharging, and status reporting of the battery and incorporates safety features to prevent issues like short circuits and battery fires. It includes a distribution plane for efficient power transfer to device components based on demand, along with a dedicated Buck converter for optimizing voltage levels required by individual components. The components that operate on the same voltages are grouped in a single power rail which gets its power from the distribution plane via the Buck converter provided within the battery management system.

[0067] Moreover, the wearable fitness device can advantageously be used as a means for evaluating overall workout effectiveness without having to tote around cumbersome equipment, while using traditional training methods. This makes the use of the device feasible for beginners to advanced levels of fitness training by athletes, sports persons, gym goers, and/or any fitness enthusiasts by providing enhanced measurement accuracy and activity tracking. This in turn enables more precise and reliable tracking/monitoring of the wearer’s fitness and training progress in comparison to conventional wearables.

[0068] Lastly, a variety of related health parameters can also be derived and extrapolated from the directly acquired and measured parameters by the device, thus providing high-resolution, high-fidelity data for multiple parameters that represent a physical activity’s derived metrics.

[0069] The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within understood that the phraseology or the terminology employed herein is for description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the appended claims.
