BACKGROUND OF THE INVENTION Field of the Art

The disclosure relates to the field of health monitoring devices, specifically the field of wearable health monitoring devices connected to cloud-based predictive networks.

Discussion of the State of the Art

It is currently possible for an athlete of any skill or dedication to go into a gym and find many types of exercise machinery, some of which may have computer chips and various levels of software on them, and some of which may be entirely mechanical in nature. Software-ready electronics are common in stationary bikes, elliptical machines, and treadmills, and in some cases exist for more specialized uses such as measuring the force exerted by a punch for boxing and other martial arts. These electronics and the software systems running on them can measure things such as estimated burned calories in a workout, the force and speed of punches or of running, the Revolutions Per Minute (RPM) of a bike and what this means for distance based on a user's settings on a stationary bike, and in some cases treadmills, elliptical machines and stationary bikes may even allow music or TV to be streamed to the user to enhance the pleasure of working out.

However, electronics with specialized software are noticeably lacking in the area of weight training, of virtually all kinds. There exists no common system which may determine the stresses an individual is undergoing while lifting in a variety of positions and warn them of, for example, poor form, uneven stresses in muscles such as if they are bench pressing, out of bounds positions such as overextending your arms during lateral pulldowns and other exercises, and more.

As well, none of the systems even in exercise machines currently, utilize machine learning and a large number of factors and biometric data to determine and accurately predict health events relevant to a user's exercise before they occur, nor do they often consider or warn a user of improper form during exercise, or for over-training or over-exertion, or myriad other concerns when engaging in strenuous physical activity. This results in users often achieving sub-par results from athletic activity, and being at-risk for health events from improper or overly taxing exercise, with workout equipment ill-equipped to aid or even consider these possibilities or users who have already suffered health events at all.

What is needed is a system and methods for a predictive health monitoring system utilizing a smart exercise belt which may aid in exercises for users to monitor their health and exercise form and progression, and more, and communicate with users to warn them of any health-related or exercise-related issues, with the goal of preventing future incidents if possible, warning users of impending or possible incidents in the near future, and aiding users in exercising both effectively and safely.

Further, for one or more of the aspects described herein, numerous alternative arrangements may be described; it should be appreciated that these are presented for illustrative purposes only and are not limiting of the aspects contained herein or the claims presented herein in any way. One or more of the arrangements may be widely applicable to numerous aspects, as may be readily apparent from the disclosure. In general, arrangements are described in sufficient detail to enable those skilled in the art to practice one or more of the aspects, and it should be appreciated that other arrangements may be utilized and that structural, logical, software, electrical and other changes may be made without departing from the scope of the particular aspects. Particular features of one or more of the aspects described herein may be described with reference to one or more particular aspects or figures that form a part of the present disclosure, and in which are shown, by way of illustration, specific arrangements of one or more of the aspects. It should be appreciated, however, that such features are not limited to usage in the one or more particular aspects or figures with reference to which they are described. The present disclosure is neither a literal description of all arrangements of one or more of the aspects nor a listing of features of one or more of the aspects that must be present in all arrangements.

Headings of sections provided in this patent application and the title of this patent application are for convenience only, and are not to be taken as limiting the disclosure in any way.

Devices that are in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. In addition, devices that are in communication with each other may communicate directly or indirectly through one or more communication means or intermediaries, logical or physical.

A description of an aspect with several components in communication with each other does not imply that all such components are required. To the contrary, a variety of optional components may be described to illustrate a wide variety of possible aspects and in order to more fully illustrate one or more aspects. Similarly, although process steps, method steps, algorithms or the like may be described in a sequential order, such processes, methods and algorithms may generally be configured to work in alternate orders, unless specifically stated to the contrary. In other words, any sequence or order of steps that may be described in this patent application does not, in and of itself, indicate a requirement that the steps be performed in that order. The steps of described processes may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to one or more of the aspects, and does not imply that the illustrated process is preferred. Also, steps are generally described once per aspect, but this does not mean they must occur once, or that they may only occur once each time a process, method, or algorithm is carried out or executed. Some steps may be omitted in some aspects or some occurrences, or some steps may be executed more than once in a given aspect or occurrence.

When a single device or article is described herein, it will be readily apparent that more than one device or article may be used in place of a single device or article. Similarly, where more than one device or article is described herein, it will be readily apparent that a single device or article may be used in place of the more than one device or article.

The functionality or the features of a device may be alternatively embodied by one or more other devices that are not explicitly described as having such functionality or features. Thus, other aspects need not include the device itself.

Techniques and mechanisms described or referenced herein will sometimes be described in singular form for clarity. However, it should be appreciated that particular aspects may include multiple iterations of a technique or multiple instantiations of a mechanism unless noted otherwise. Process descriptions or blocks in figures should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process. Alternate implementations are included within the scope of various aspects in which, for example, functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those having ordinary skill in the art.

Conceptual Architecture

FIG. 1 is an exemplary diagram illustrating a plurality of sensors and sensory data that may be collected as input. Sensor inputs 110 may comprise electro-encephalography (EEG) sensors 115, electromyography (EMG) sensors 120, strain or pressure gauges 125, plethysmographs for detecting blood pressure 130, oximeters 135, GPS sensors 140, altitude sensors 145, temperature, humidity, and other relevant climate or weather sensors or networked devices that may obtain such information from the Internet 150, gyroscopes 155, accelerometers 160, breathing sensors 165, and heart rate monitors 170. The sensor inputs 110 may be gathered from sensors placed on or attached to a wearable device, as shown in other drawings, which may be attached to a user during exercise or other physical activity for the purposes of both building a model of user data such as health data and exercise habits, and for predictive health monitoring as a result of this model.

FIG. 2 is an exemplary diagram of various forms of gathered and monitored user data that may be monitored for changes both in an individual user and in user groups, and which may be correlated together using machine learning to find relationships between data values and changes in data values. Multiple groups of data may influence each other and be collected in relation to one another, for instance the health profile 220 of a user and the type of exercise they are performing or continually perform 240 may be analyzed together to determine if someone is performing exercises that are more likely to lead to certain injuries, in a predictive health monitoring system. Categories of monitored and acquired data includes data on comparison group size 210, for instance analyzing statistics of other groups according to groups of varying granularity such as national 213 or individual 215 data, health profiles of users 220, user ages 230, type of exercises performed 240, training goals 250, and environmental data 260. The comparison group size category of data 210, may include, for example, classifications including global 211, regional 212, national 213, group 214, and self 215, allowing data to be analyzed or corrected for comparison to varying groups of people for differing statistical analyses. The category of health profiles 220 may include, for example, data on user Body Mass Index (BMI) 221, fitness level 222, tobacco use 223, alcohol use 224, family history 225, and medical history 226, allowing for model construction to take into account health information on users. The data category of user age 230, may include age groupings, for example decadal age groupings, grouping together users who are less than 20 years old 231, 20-29 years old 232, 30-39 years old 233, 40-49 years old 234, 50-59 years old 235, 60-69 years old 236, and 70 or more years old 237, allowing prediction and model-building of health profiles and warnings where age is taken into account (for instance, users of a predictive health monitoring system who are 30-39 years old might be calculated to be at less risk of hip displacement during squats than users who are 60-69 years old, all other factors being equal). The data category relating to the type of exercise 240 a user or users perform may include any type of exercise, for example, running 241, swimming 242, cycling 243, rowing 244, or other types of exercise, allowing, for instance, a user's health predictions to take into account their age and the statistics of their region for individuals of similar age, but also refine the analysis to individuals and risks undertaken when a user participates in specified exercises. In this way, a user's health predictions will be different for differing exercises from another user, all other factors being equal. The data category of training goals 250 may include, for example, whether a user is training for strength 251, endurance 252, speed 253, or general fitness 254, which may be analyzed in the context of different intensities and practices of the exercise. For instance, an individual who is practicing weight-lifting for maximum strength gain may be assumed to be using heavier weights than an individual who is only training for endurance or general fitness, which may be taken into consideration for predicting user health risks and events ahead of time. The data category of environmental data 260 may include, for example, analyzing ambient and user temperature 261, humidity 262, altitude 263, terrain 264, and the rates of change of these datapoints, for instance the rate of change of the temperature as they are running outside 265. With these factors being analyzed together rather than only separately, health predictions may take on a much more holistic approach and be more accurately attuned to a specific user, for heightened accuracy. For instance, a user may be recorded as being 35 years old, be an occasional smoker, desire to train for a marathon with cycling, running, and swimming, and be monitored during a swim in a warm pool. In such an instance, if their region shows individuals in similar circumstances (similar age range, health background, and exercise form and goals) have a significantly increased risk of heart attack if they undergo the exercise at a high intensity, but not if the exercise is performed at a lower intensity or in a colder pool, the system may warn them to take these precautions ahead of time, aiding to mitigate the risks of such health events. This warning may be displayed on a connected phone or computer, or with a connected audio device, to warn or inform a user.

FIG. 3 is an exemplary diagram of diagram illustrating groups of related applications for the disclosed invention. One application is athletic training 310, for which the system is usable and optimized for analyzing and predicting optimal exercise measurement 311 such as predicting and detecting the movements of a user during exercise to determine if they are exercising optimally, this being accomplished with the plurality of sensors such as EMG, gyroscopes, and accelerometers on the device, over-training prediction 312 such that users who train too frequently on any given exercise may be warned due to higher risk of injury and lower fitness gains from over-training the body, endurance training 313 such as recommending to a user optimal exercises to increase endurance based on the totality of their data with the system, strength training 314 such as recommending optimal exercises for strength gain for a user, long-term performance tracking and prediction 315 which requires longer usage of the system but may be utilized to recommend more effective, or safer, or both, training programs and activities for a user. Another application is found in preventative medicine 320, including stroke prediction 321, heart attack prediction 322, fall prevention 323, and heat exhaustion or over-exercising warnings 324. These warnings are a result of the confluence of multiple factors including a user's age, nationality, fitness levels, exercise history, medical history, and more, and may be fine-tuned and made more accurate over time from both group statistical data and more refined data on a particular user. A third family of applications include medical rehabilitation 330, such as pre-stroke and post-stroke analysis 331, pre-heart attack and post-heart attack analysis 332, and post-trauma predictive warnings 333. Pre-stroke and post-stroke analysis 331 may take the form of monitoring a user's biometric feedback during exercise and physical activity both before and after a stroke event, and comparing them to determine patterns of behavior and user performance and health changes after a stroke event occurs. Similar methodology may be applied for analysis of a user before and after a heart attack 332, while post-trauma predictive warnings 333 may warn a user of likely health risks and possible injuries for specific exercises or other relevant data.

FIG. 4 is an exemplary diagram illustrating the progression of quality of predictions for a user over time, illustrating an initial predictive technique, a short-term improvement on predictive technique, and progression through medium-term and long-term data gathering to further improve predictive techniques for users. There is a flow of data leading from an initial data availability and predictive quality using global or national statistical data 410, indicating the use of broadly available data such as national averages of hip displacement for individuals in a broad age range. This stage represents a lack of narrower regional data or personal data from a user, and represents the lowest accuracy and specificity with predictive health reporting. A second stage is short-term improvements of data availability and predictive quality, using more regional statistical data 420, for instance if a small area such as a single US state or even a single city has a different rate of risks for certain health and wellness events, for instance if people in a certain area experience more bone fractures or joint displacements for some reason, or higher incidences of heart attacks. A next stage involves medium-term improvements of data availability and predictive quality, using statistical data from smaller groups with similar characteristics to each other, for example groups of people who suffer strokes between the ages of 40-59 in California 430 and have moderate smoking habits, with a final stage of long-term improvements of data availability and predictive quality, using an individual user's prior history, including exercise and physiological records 440. As user data and global, national, regional, and local statistical and health data becomes more available, over time, the predictive quality of the system improves as shown.

FIG. 5 is an exemplary diagram illustrating the overlap and confluence of various factors to achieve the greatest predictive value from overlapping data from all factors, including factors such as group size, user age, health data, and more. Comparison group size 510, environmental data 520, type of exercise 530, training goals 540, health profiles 550, and age 560 data categories all are utilized to achieve a greatest predictive value 570, rather than analyzing a user on only one analysis vector such as the type of exercise 530.

FIG. 6 is an exemplary diagram illustrating an exemplary structure of a system of neural networks operating on a confluence of factors related to a user's data as acquired by a system of sensors. Individual first-stage neural networks operate to analyze data based on a health-related factor such as comparison groups 605, age 615, health profile 625, training goals 635, exercise type 645, and environment 655. Each first-stage neural network evaluates the relevant data to find patterns of data in that category that lead to health events, utilizing descent gradient training and back propagation as shown in later drawings, and is configured to make a health prediction based on that health-related factor, for example a prediction based on the comparison group 610, a prediction based on age 620, a prediction based on the user's health profile 630, a prediction based on training goals 640, a prediction based on type of exercise 650, and a prediction based on the environment in which the user is exercising 660. These separate first-stage health predictions are then input into a second-stage neural network 665 (also called a confluence of factors neural network) that is configured to make a second health prediction 670 (also called a confluence of factors prediction) based on a combination of the first health predictions from at least two of the plurality of first-stage neural networks. The confluence of factors prediction 670 is then validated against 680 the aggregated results of the first-stage predictions 675 to ensure that the confluence neural network 665 is not overfitting to the data. In some embodiments, the validation 680 may comprise a combination or convolution of the separate neural network predictions 675 and the confluence factors prediction 670 to produce a third health prediction or to produce a confirming health prediction of either the separate neural network predictions 675 or the confluence factors prediction 670.

FIG. 7 is an exemplary diagram illustrating an exemplary series of events leading to a health event that may be predicted by training neural networks using back propagation. In this example, a series of difficult-to-correlate events leads to a heart attack. Neural networks, trained on many, many similar events using back propagation, are able to connect and identify patterns of such events and build predictive models based on such training. Here, a traumatic health event occurs 780, in this case a heart attack, and the system examines the previous events leading up to the heart attack through back propagation. In this example it sees several events occur for a user before the heart attack, including a heart irregularity identification event 710 which can be an anomaly in the heartrate or pulse of a user, an exercise change event from running to cycling 720, a group age identification event 730 at which point the system identified the user as part of a new group of similar users due to current trends and user events, a training goal change event, indicating a goal to train for a cycling competition 740, an individual age identification event 750 which can occur due to an age change, or the user's age only now being input into the system, or may be the result of the system merely making note of the user's age in the back propagation even if the user's age did not change immediately prior to the heart attack, an exercise change event from cycling to rowing 760, and an environmental change event, in this example a 10 degree shift in temperature of the surrounding environment 770. Through examining similar series of events for large numbers of users and large amounts of data, the neural network is able to detect repeatable patterns in seemingly unrelated events which are predictive of health outcomes. Neural networks may be configured to detect such patterns within a single health-related factor. For example, a series of changes in a user's health profile that lead to a heart attack such as weight gain, followed by increased cholesterol levels, followed by high blood sugar levels. Neural networks may be used at a first stage to detect such patterns. More difficult to detect are patterns of health events across health factors. A neural network may be configured to analyze a confluence of factors to detect seemingly unrelated events that show a repeatable pattern of prediction of certain health outcomes. The example in this diagram shows, for example, a heart irregularity 710 followed by a couple of age-related thresholds 730 and 750, combined with two type of exercise changes 720 and 760, a training goal change 740, and a temperature change during exercise 770. It is unlikely that these events would have been correlated with the heart attack by standard health prediction models, but neural networks excel at identifying such patterns and correlations over large sets of data.

FIG. 8 is an exemplary diagram of sensors being connected to a wearable device, for the gathering of data on a user during physical activities. A wearable device 810 as shown may be in the form of a weight belt, a wrist strap, an arm band, a chest strap, or may be formed into a vest or other wearable configuration. The wearable device 810 comprises core computing device components 820 and one or more sensors 830, which may be built-in or may be in the form of removable or exchangeable attachments. Other external sensors may be attached via wires, cables, or wireless devices, for example EEG sensors could be connected via one set of connections 811 and EMG sensors could be connected via a second set of connections 812. These core components may comprise a network adapter 821, a processor 822, and a digital memory storage 823, such that the sensor data may be processed and the harness may connect to an auxiliary device such as a smartphone to give the user the relevant health warnings as needed. One or more additional sensor attachments on the exercise and health prediction belt 830 exist, including a strain gauge or gauges 831, a plethysmograph 832, a gyroscope 833, an oximeter 834, an accelerometer 835, a heart rate monitor 836, and a pressure sensor or plurality of pressure sensors 837. These sensors are relatively common sensing and health monitoring devices, and with the EEG 811 and EMG 812 sensors, allow the wearable device to detect the plurality of biometric and positioning data about a user required for neural networks to learn to predict health-related events during exercise.

FIG. 9 is an exemplary method for predictive health monitoring using neural networks. First, a predictive health monitoring harness obtains biometric data for a user of a wearable biometric monitoring and feedback device 910, before retrieving a history of biometric data and a history of health predictions for the user from a data storage device 920, such a data storage device either being a memory in the harness or being stored on a peripheral device such as a smartphone that may be connected to the harness. Processing the biometric data, history of biometric data, and the history of health predictions through at least two of a plurality of first-stage neural networks is then performed, the plurality of first-stage neural networks, each configured to make a first health prediction based on a separate health-related factor 930, before receiving a first health prediction from each first-stage neural network through which the biometric data was processed 940. The system then processes the first health predictions received through a second-stage neural network, the second-stage neural network configured to make a second health prediction based on a combination of the first health predictions from at least two of the plurality of first-stage neural networks 950, receiving the second health prediction from the second-stage neural network 960 and then displaying the second health prediction to the user of the wearable biometric monitoring and feedback device 970, through either a connected display, smartphone, or other device that can connect over a network to the monitoring harness.
