FIELD OF THE INVENTION
The present invention relates generally to a system to detect falls. More specifically, the present invention is a footwear integrated system that detects falls, obstacles and hazards, and responds accordingly, while using machine learning algorithms and data processing to differentiate between true fall events and false positives.
BACKGROUND OF THE INVENTION
The purpose of the invention is to develop a sophisticated smart shoe system capable of detecting user falls, identifying obstacles and hazards, and alerting users the same. The system not only provides data to general users but may also extend its use cases to disabled individuals, elderly populations, diabetics, and professionals such as firefighters. The incorporation of multiple sensors into shoes and a machine learning system distinguishes provides a utility not presented in the prior art by offering an advanced means of identifying true fall events and potential dangers.
For disabled users, especially those with limited mobility, falls can lead to serious injuries and prolonged recovery periods. The smart shoe system addresses this concern by providing real-time fall detection and immediate alerts, ensuring prompt medical assistance. Furthermore, the system's capacity to detect obstacles proves valuable in enhancing navigation for visually impaired users, as well as aiding those with mobility challenges. The functionality of this smart shoe system is not limited to the general public, however, but rather it extends to professionals in high-risk environments. Firefighters, for example, often operate in hazardous conditions with limited visibility and thus the shoe's ability to identify fire hazards enhances their situational awareness, enabling quicker response times and improved safety measures. Additionally, the system may be used to identify a true fall when a firefighter falls and becomes unconscious while he is saving other people.
Existing fall detection systems often rely on wearable devices that cannot differentiate between a true positive and a false positive, referred to herein as true falls and false falls, respectively. Additionally, some systems within the prior art lack accuracy, leading to a high rate of false-falls alarms, which reduces user trust and adoption. Moreover, many solutions overlook the critical aspect of identifying fire hazards or obstacles, leaving users vulnerable to potentially life-threatening situations. Also, the prior art systems do not implement response systems (e.g. protecting the user body using airbags system when falls is recorded) into the shoes but rather only provide data to a user.
The current technologies also fail to cater to specific user groups like firefighters, who require specialized tools to address their unique needs. Conventional footwear, even with added sensors, does not offer the comprehensive functionalities of the proposed smart shoe system.
The present invention may also be useful for powerline workers. In a situation wherein a powerline worker is wearing the shoes while working on elevated electrical powerlines, if he falls, then the present invention can monitor the change in the altitude during the fall using the GPS that is affixed to his shoes. Based on the change in the altitude value, the microcontroller in the first step sends a command to the airbags to be filled with air, thus reducing the risk of bone fractures. In the second step, the system sends a message to the caretaker including the user's location and the level of possible harm.
Additionally, the prior art does not classify the level of harm caused by a fall wherein the present invention is able to do so using the Global Positioning System (GPS) by measuring the altitude during the user fall, and classifying the fall based on the altitude value. Furthermore, the prior art does not disclose a means for protection to protect the user from various hazards during falls. However, the present invention is able to do so by providing a set of airbags that are affixed to various parts of the user body and controlled using a microcontroller. These bags are filled with air during a fall and thus prevent bone fractures. If a fall occurs in water, these bags prevent the user from drowning risks. In addition, no prior art systems investigated the integration of the functionality of the light sensor, the load scale sensor and the vibration sensor in determining if the user is wearing his shoes or not.
An objective of the present invention is to accurately detect true fall events while minimizing false positives. The system's integrated array of sensors works collaboratively to distinguish between normal activities and genuine falls, preventing unnecessary alarms and protecting the user body using a set of airbags. An additional objective is to enable users to navigate through obstacles and hazards efficiently. By employing a combination of depth perception, temperature sensors, and fire detection mechanisms, the system not only identifies physical barriers but also identifies fire risks, enhancing overall safety. The integration of multiple sensors facilitates the collection of comprehensive data, contributing to accurate fall detection, hazard identification, and environmental awareness. Further, a machine learning system employs pattern recognition and anomaly detection algorithms, enhancing the system's ability to distinguish between false positives and true fall events.
In conclusion, the proposed smart shoe system represents an innovative advancement in fall detection, hazard warning, body protection (using airbags system) and user assistance (with the help of the GPS system affixed to the user shoes). By addressing the limitations of existing solutions and catering to the needs of disabled individuals and professionals alike, this invention promises to enhance safety, mobility, and situational awareness in a variety of contexts. Through the integration of advanced sensors, machine learning capabilities, and user-friendly design, the smart shoe system introduces a comprehensive and reliable solution to the challenges faced by users in both everyday scenarios and specialized professions.
SUMMARY OF THE INVENTION
A footwear integrated system for detecting falls, avoiding hazards, and responding to events (e.g. protecting the user body using airbags system when a fall occurs, responds to drowning risks, and determine the user location using a GPS system) having a system of sensors to determine various metrics pertaining to the status of the user. The system comprises multiple sensors that work collaboratively to determine whether the shoe is being worn by the user as a means to prevent a false positive reading (i.e. false falls). Additionally, a user worn inflation device, water detection sensors, and geographic positioning systems allow for the system to respond to drowning risks. A mobile application in addition to the footwear allows for communication with a cloud network to process data, analyze data using machine learning systems, and retrieve data in real time.

If the shoes 10 are being worn by the user 203b, in a fourth step 204, given that the system 2 determines that the shoes 10 are being worn, the machine learning algorithm 414 analyzes the data provided by the plurality of sensors 110 including the plurality of floor sensors 111 and the location data from the geographic positioning device 116 to compare the input data from said sensors 111,116 to a set of predetermined thresholds. If the thresholds are met 204b, the algorithm 414 determines that a true fall occurred and a subsequent fifth step 205 is initiated. In the fifth step 205, the presence of the true fall event to the microcontroller 122 and the user worn inflation device 20. Following the communication to the microcontroller 122 and the user worn inflation device 20, a sixth step 206 is initiated wherein said step 206, the user worn inflation device 20 is deployed. In the preferred embodiment, upon determining that the user is in an environment having a risk of true fall, the electric air pump 23 fills the bladder 21 of the inflation device 20, thus protecting the user from the risk of injury. Next, in a seventh step 207, an alert is sent to the caretaker mobile 50 device informing the caretaker of the true fall event of the user and the location of the user.

If the machine learning algorithm 414 determines, upon processing the data gathered by the plurality of floor sensors 111, determines that the plurality of floor sensors have detected a ground surface 204b, then the system establishes that a true fall event has occurred and triggers the subsequent fifth step 205. Otherwise, if the system does not determine that the plurality of floor sensors have detected a ground surface 204a, then the process 2 will reiterate, continuing to gather data.
As shown in FIG. 15, the present invention comprises a process for detecting and informing the user of an obstacle hazard 3 comprising a plurality of steps. In a first step 301, data is gathered from the plurality of sensors 110. The sensors 110 communicate the data to the microcontroller 122 wherein the microcontroller 122 then transmits the data to the cloud network 40. In a second step 302, the data that has been transmitted to the cloud network 40 is then accessed and read by the mobile application 31. The mobile application 31 uses the machine learning algorithm 414 to analyze the data. Next, in a third step 303, the machine learning algorithm 414 and the mobile application 31 determine if the shoes 10 are being worn by the user. The machine learning algorithm 414 compares the data collected from the sensors 110 to predetermined minimum thresholds wherein all of the predetermined thresholds must be met for the algorithm 414 to determine that the shoes 10 are being worn by the user. In the preferred embodiment of the present invention, the light sensor 112, the load scale sensor 113, and the vibration sensor 118 contribute to input data in the determination of whether the shoes 10 are being worn. In the preferred embodiment of the present invention, the threshold for the load scale sensor 113 is 50 kilograms. If the shoes are being worn 303b, in a fourth step, the mobile application 31 analyzes the data provided by the ultrasonic sensor 114 to compare the input data from said sensor 114 to a predetermined threshold. If the threshold is met, the mobile application 31 determines that an obstacle is within the path of motion of the user 304b and a subsequent fifth step 305 is initiated. In the preferred embodiment, the threshold for the distance between the ultrasonic sensor 114 and the obstacle is 30 centimeters. Thus, in the preferred embodiment, if the obstacle is within less than or equal to 30 centimeters, then the fifth step 305 will initiate wherein, data communicating the presence of the obstacle is delivered to the user mobile device 30. Next, in a sixth step 306, the user mobile device 30 provides an audio message informing the user of the approaching obstacle.
As shown in FIG. 16, the present invention comprises a process for detecting and informing the user of a high temperature hazard 4 comprising a plurality of steps.

The sensors 110 communicate the data to the microcontroller 122 wherein the microcontroller 122 then transmits the data to the cloud network 40. In a second step 402, the data that has been transmitted to the cloud network 40 is then accessed and read by the mobile application 31. The mobile application 31 uses the machine learning algorithm 414 to analyze the data. Next, in a third step 403, the machine learning algorithm 414 and the mobile application 31 determine if the shoes 10 are being worn by the user. The machine learning algorithm 414 compares the data collected from the sensors 110 to predetermined minimum thresholds wherein all of the predetermined thresholds must be met for the algorithm 414 to determine that the shoes 10 are being worn by the user. In the preferred embodiment of the present invention, the light sensor 112, the load scale sensor 113, and the vibration sensor 118 contribute to input data in the determination of whether the shoes 10 are being worn. In the preferred embodiment of the present invention, the threshold for the load scale sensor is 50 kilograms. In a fourth step 404, given that the system determines that the shoes are being worn 403b, the mobile application 31 analyzes the data provided by the temperature sensor 115 to compare the input data from said sensor to a predetermined threshold. If the threshold is met, the algorithm 414 determines that a fire hazard is within the path of motion of the user 404b and a subsequent fifth step 405 is initiated. In the preferred embodiment, the threshold for the temperature reading is 40° C. Thus, in the preferred embodiment, if temperature is greater than or equal to 40° C., then the fifth step 405 will initiate. In the fifth step 405, data communicating the presence of the hazard is delivered to the user mobile device 30. Next, in a sixth step 406, the user mobile device 30 provides an audio message informing the user of the approaching hazard.
As shown in FIG. 17, the present invention comprises a process for detecting and responding to a potential drowning risk (i.e. a water hazard) 5 comprising a plurality of steps. In a first step 501, data is gathered from the plurality of sensors 110. The sensors 110 communicate the data to the microcontroller 122 wherein the microcontroller 122 then transmits the data to the cloud network 40. In a second step 502, the data that has been transmitted to the cloud network 40 is then accessed and read by the mobile application 31. The mobile application 31 uses the machine learning algorithm 414 to analyze the data. Next, in a third step 503, the machine learning algorithm 414 and the mobile application 31 determine if the shoes 10 are being worn by the user. The machine learning algorithm 414 compares the data collected from the sensors 110 to predetermined minimum thresholds wherein all of the predetermined thresholds must be met for the algorithm 414 to determine that the shoes 10 are being worn by the user. In the preferred embodiment of the present invention, the light sensor 112, the load scale sensor 113, and the vibration sensor 118 contribute to input data in the determination of whether the shoes 10 are being worn. In the preferred embodiment of the present invention, the threshold for the load scale sensor 113 is 50 kilograms. Next, in a fourth step 504, given that the system determines that the shoes are being worn 503b, the machine learning algorithm 414 analyzes the data provided by the plurality of sensors 110, specifically, the water detection sensor 117 and the location data from the geographic positioning device 116 to compare the input data from said sensors 116,117 to a set of predetermined thresholds. If the thresholds are met, the algorithm 414 determines that a user is likely in a hazardous environment wherein the risk of drowning is highly present 504b, and a subsequent fifth step 505 is initiated. The fifth step 505 comprises the communication of data to the microcontroller 122 of the user worn inflation device 20 indicating the drowning risk. Once the data indicating a drowning risk is received, a sixth step 506 initiates wherein the deployment of the user worn inflation device 20 occurs. In the preferred embodiment, upon determining that the user is in an environment having a risk of drowning, the electric air pump 23 fills the bladder 21 of the inflation device 20, thus providing additional buoyancy to the user. In the preferred embodiment, the inflation device 20 is especially functional in the event that the user was rendered unconscious during the fall. In a seventh step 507, an alert is sent to the caretaker mobile device 50 informing the caretaker of the location of the user and the potential threat that exists. In some embodiments, the alert is sent via short messaging service (SMS). In alternate embodiments of the present invention, the alert is sent via a notification through the mobile application 51. In additional embodiments of the present invention, a voice alert notifies the user of a hazard event.
As shown in FIG. 18 in the preferred embodiment of the present invention, during the determination of whether the shoes are being worn by the user in the third steps of the aforementioned processes 203, 303, 403, 503, data gathered from the light sensor 112, the load scale sensor 113, and the vibration sensor 118 is analyzed to determine if the shoes are being worn. If the data gathered by each of the light sensor 112, the load scale sensor 113, and the vibration sensor 118 is determined to be above a predetermined threshold, then the machine learning algorithm 414 will determine that the shoes 10 are being worn by the user. In the event that any of the data gathered by each of the light sensor 112, the load scale sensor 113, and the vibration sensor 118 is determined to be below a predetermined threshold, the machine learning algorithm 414 will determine that the user is not wearing the shoes 10. If the machine learning algorithm 414 determines that the shoes 10 are being worn, then the subsequent step is initiated. Contrarily, if the machine learning algorithm 414 determines that the shoes 10 are not being worn, the system will continue to gather information.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention.
