The present invention relates generally to water sports and, more particularly, to a method and an apparatus for automating and enhancing situational awareness for enabling safe towable recreation. The implementation of the disclosed method and apparatus automates several manual elements currently required during the towable recreation and enables safe vessel (tow watercraft) recreation. It also improves the safety of participants and property in the area of the tow watercraft recreational operation. When a participant gets submerged in the water, the communication is ceased, thus initiating a flag to go up automatically and initiates the alarm to alert the captain of the watercraft. Deployment of the flag lets surrounding watercraft to know that the participant is in the water.
People participate in a wide variety of watersports, with more seemingly being created all the time. Such sports include surfing, stand up paddling, rafting, kayaking, wake boarding, water skiing, tow watercraft recreation, snorkeling, kite boarding, canoeing, parasailing, diving, or the like. Among all these water activities, towboat recreation has become a more popular activity both at the participant, athletic, and tournament levels. As is well known, the outboard or inboard motors of tow watercrafts produce a wake which extends rearwardly from the stern of the tow watercrafts for a number of feet. The participant grasps a tow rope attached to a pylon mounted to the tow watercraft and/or Bimini of the tow watercraft, typically maneuver in a side-to-side direction, back and forth across the wake, during a towing run. The extent of side-to-side movement of the participant can vary significantly depending on the length of the tow rope, the skill of the participant, the type of activities being performed during a tow run, and the like. However, during the towable recreation, safety of the participants has been always a big concern. Due to lack of efficient and effective safety measures while practicing towing recreation, accidents are on the rise. Currently, the safety management of the participant is done manually. Also, while recreating, it is not uncommon for a tow watercraft driver and/or a person monitoring the participant to become fatigued, bored, or distracted. This may lead to accidents and inefficiencies in boating operations. In light of the foregoing, there exists a need for a technical and reliable solution that solves the above-mentioned problems and automates these manual functions and make them more reliable, effective, and safe.
It will be understood that this disclosure is not limited to the apparatus described herein, as there can be multiple possible embodiments of the present disclosure which are not expressly illustrated in the present disclosure. It is also to be understood that the terminology used in the description is for the purpose of describing the versions or embodiments only and is not intended to limit the scope of the present disclosure.
When a participant wants to be towed, it generally requires two other people to facilitate the activity. A first person may operate a tow watercraft by controlling both speed and direction. The watercraft may correspond to at least one of but not limited to a stand-up paddle board, rowboat, canoe, river raft, jet ski, jet boat, hydrofoil, or inner tube. Also, the first person is responsible for detecting and avoiding potential collisions and myriads of other dangers in and around the tow watercraft in the water. A second person is generally required to manage the logistics of towing the person behind the tow watercraft. The present invention, disclosed herein, provides a central controller or actuator to reduce the manual effort required to support tow watercraft recreation, while improving situational awareness to all the stakeholders, thereby, improving safety, increasing fun, and reducing maintenance and operating cost. As the components of the tow watercraft recreational equipment become connected to the Internet, big data analytics may be incorporated to identify trends that can be leveraged for further product optimization. Prior to the identification of the trends, the relevant data is acquired from one or more controllers of one or more tow watercrafts, and then the relevant data is processed to determine useful and real-time trends associated with the tow watercraft recreational activities that are happening in and around. Further, at least one of the acquired data and the one or more trends may be discernment to one or more other tow watercrafts, participants, or equipment. These data and trends may be rendered via one or more application portals (i.e., software applications) running on one or more respective devices such as user devices or tow watercraft devices. In addition to this, the present invention also discloses capturing, transferring, and using user data. The main purposes include data collection and mining, machine learning, social sharing, or the like.
Another objective of the present invention is to manage the rope operation during the tow watercraft recreation. In an embodiment, both the launching and retrieval of a tow rope that is tethered to the tow watercraft and projected to a participant may be managed to facilitate towing behind the tow watercraft. In an embodiment, the participant may hold on to the tow rope to be towed at speeds which allow the participant to glide on top of the water and recreate. The disclosed invention facilitates monitoring of all the personnel (such as the participant, driver, observer, swimmers, passengers, and others) engaged in being towed operation. The disclosed invention further facilitates automatic generation of signals when the participant is down. The disclosed invention further facilitates to create a network of multiple tow watercrafts on the lake to provide an extended level of system operation, control, and optimization. For example, the acquired data and the generated trends may be discernment to the one or more tow watercrafts on the lake for facilitating ease of operation and control, along with the extended optimization.
Another objective of the present invention is to provide an apparatus for RTB (recreational tow watercraft) automation and enhanced situational awareness. The apparatus is configured to facilitate:
Launch Attachment and Retrieval—Automatically gets the tow rope from the tow watercraft to the participant. In an embodiment, the rope projection and retrieval may be realized pneumatically or with a spring energy storage mechanism. The material could have a significant impact on manufacturing, cost, and reliability.
Monitor and Control—Detect the personnel (such as the participant, driver, observer, swimmers, passengers, and others) engaged in the recreation operation in and around the tow watercraft. Monitoring may be facilitated with several methods of location technology. These include, but are not limited to, Sonar, Radar, Lidar, GPS, Differential GPS, or any combination thereof.
Detect, Avoid, and Signal—Using Sonar, Radar, Lidar, Visual, and GPS data, the apparatus is configured to determine or track location of all stakeholders associated with the tow watercraft and/or other watercrafts in and around the tow watercraft and manage movements to safely operate the recreational activities or other water sport activities. The aim is to find the participant and avoid everything else. In case of any accidental events or mishap, the operator (such as the driver of the tow watercraft) notifies or signals that the participant is down. Such notifications or signals may be communicated to rescue personnel or other watercrafts in its vicinity. Signaling may be achieved with multiple modalities. These include, but are not limited to, auditory, visual, mechanical, or any combination thereof.
Big Data—Collection and processing of Sonar data, Radar data, Lidar data, Visual data, and Position data to track movements in and around the tow watercraft and participant and automatically generate signals when the participant is down
Analytics—Big data is processed and analyzed to optimize system performance
Networking and Engagement—Create a network of multiple tow watercrafts during recreation activities to provide an extended level of system operation, control, and optimization. For example, the acquired data and the generated trends may be discernment to the one or more tow watercrafts on the lake for facilitating ease of operation and control, along with the extended optimization. These data and trends may be rendered via one or more application portals (i.e., software applications) running on one or more respective devices such as user devices or tow watercraft devices. In addition to this, the present invention also discloses capturing, transferring, and using user data. The main purposes include data collection and mining, machine learning, social sharing, or the like.
The apparatus may be configured to integrate these primary functions using various components such as a controller (for facilitating one or more outputs), one or more sensors (for sensing and collecting input data), a memory (for data acquisition and discernment to one or more vessels, participants, and equipment), engagement (via one or more application portals), and networking (for establishing connectivity of one vessel, for example, tow watercraft) to other like vessels (for example, other tow watercrafts in its vicinity). Each part of the present invention complements the overall performance and safety of the total tow watercraft recreation system. This concept may be a full system or a sub-system implementation that could fully or partially enhance the operation and safety of the tow watercraft recreation or blend into a top-level system provided by another party.
Another objective includes to provide a system to sense immersion of a participant into water. The system comprises a smart flag and an alarm device on a watercraft, and a FOB device of a participant. The smart flag, the alarm, and the FOB device are wirelessly connected to each other. The FOB device detects the immersion of the participant in the water. The smart flag is automatically deployed based on the detected immersion. The alarm device is automatically turned ON creating an alarm indicating an SOS signal. When the participant gets submerged in the water, the communication is ceased, thus initiating the flag to go up automatically and initiate the alarm to alert the captain of the watercraft. Deployment of the flag lets surrounding watercraft to know that the participant is in the water. The watercraft may include a kill engine or switch that is ignited to turn OFF/ground/neutralize the motor and propulsion system of the watercraft. In case of any emergency, the operator may turn ON or ignite the kill engine or switch. This causes the engine and motion of the craft to stop, presumably enabling the overboard person to swim back to the watercraft.
The described system is an advanced safety mechanism designed to ensure participant security and enhance situational awareness during water sports activities. The system integrates advanced hardware, proprietary software logic, and robust communication protocols to deliver a highly reliable and adaptable safety solution for water sports. It ensures rapid response to emergencies, precise interactions between components, and seamless communication with external devices, providing a comprehensive safety net for participants and operators alike.
At its core is a participant's FOB (frequently referred to as a “beacon”), which is configured to detect when a participant is immersed in water. This FOB device incorporates a sophisticated suite of components, including a microcontroller, CPU, internal memory, external flash drive, SRAM, DRAM, IRAM, fine-grained clock, crystal oscillator, RTC, power management circuitry, Wi-Fi and Bluetooth Low Energy (LE) radios, a low noise receive amplifier, and an antenna. These components enable the FOB to wirelessly transmit and receive RF signals and data while processing received data using proprietary software logic. This high level of hardware integration allows the FOB to function as the central detection and communication unit, capable of interacting with other system components. The system also includes an alarm device, integrated into the watercraft, which is wirelessly connected to the participant's FOB. Upon detecting the participant's immersion into the water, the FOB triggers the alarm device, which activates and emits either an audible alarm, a visual signal, or both. This immediate activation ensures that both the watercraft's captain and nearby individuals are alerted to the participant's situation. Another essential element of the system is the smart flag device, mounted on the watercraft. The smart flag is equipped with an actuator for automatic deployment and a speaker housed within a robust casing. The smart flag is designed with circuitry comparable to the participant's FOB, including a microcontroller and other advanced components that allow it to wirelessly connect with both the FOB and the alarm device. When immersion is detected, the smart flag is programmed to automatically raise itself and emit a loud audible signal, ensuring that it provides clear visual and auditory cues to the surrounding area. This combination of signals is particularly beneficial in situations of poor visibility or crowded water environments, where immediate recognition of an emergency is critical. The captain's console acts as a centralized control hub, enabling the watercraft's captain to monitor, manage, and override system components. The console communicates with the participant's FOB, the alarm device, and the smart flag, allowing the captain to remotely control the flag's position, adjust alarm parameters, and configure other system features. The console is programmed to recognize the unique identifiers of each system component, ensuring logical relationships are established and false alarms are prevented. This unique identifier mechanism is particularly useful in environments where multiple boats or participants may be operating in close proximity, as it ensures the system responds only to the intended devices. Further enhancing the system's utility is a smart device application, which receives real-time updates from the participant's FOB, the smart flag, and the captain's console. The application displays the participant's location and system status, allowing the captain and other stakeholders to monitor the situation remotely. This application can also relay GPS coordinates of the smart flag when it is activated, ensuring precise tracking of the participant's location and facilitating swift recovery efforts. The participant's FOB device detects immersion through multiple mechanisms, including RF signal interruption and the analysis of data from integrated sensors. This multimodal detection approach minimizes the risk of false positives, ensuring that the system activates only in genuine emergencies. The FOB is also programmed to establish a unique identifier relationship with the smart flag. This relationship ensures that only the flag associated with the specific participant's FOB activates, even in close-proximity scenarios where other boats may be operating similar systems. This prevents unnecessary flag activations and enhances the reliability of the system. To address scenarios where the captain falls overboard, the system includes a man down switch (ECOS). This switch is installed on the watercraft and is configured to cut off the engine automatically if the captain is overboard. The ECOS operates independently from the participant's FOB, ensuring that the system remains robust and reliable in all circumstances. The smart flag is also configured to emit both visual and audible signals. This multimodal signaling ensures high visibility and audibility, particularly in challenging conditions such as low light, heavy traffic, or noisy environments. The system dynamically adjusts these signals based on the situation, enhancing its effectiveness in diverse operational scenarios.

The present invention is a water sports safety system leveraging advanced smart components to provide enhanced situational awareness, safety, and automation for recreational tow watercraft activities. The system incorporates a network of interconnected and intelligent devices, including SMART FOBs, a Smart Flag, a Captain's Console, and a Man Down Switch (ECOS), each programmed with proprietary logic for seamless integration and interaction.
The SMART FOBs are central to the system, designed with advanced hardware and software to perform beyond traditional RF transmission. Each FOB includes:
The functional capabilities include bidirectional RF and data transmission, allowing the FOB to send and receive signals and process incoming data using proprietary software logic. The functional capabilities further include unique identifiers for each FOB, enabling precise interaction with paired devices. This prevents interference and ensures safety in multi-user environments. Another example of how unique identifiers are valuable is a passive roll call function that would ensure no person is left behind. For example, if 8 snorkelers went out to swim and only 7 of them returned, the smart Flag would not return to a stowed position and the captain would be alerted that someone was not accounted for.
The smart flag is an essential safety component, equipped with:
The functional capabilities include automatically activated upon detecting submersion of the participant via paired SMART FOBs or directly by the Captain's Console. The functional capabilities further include loud audible alarms and visual signaling, ensuring that nearby watercraft and individuals are alerted to emergencies. Further, it establishes a logical relationship with paired FOBs using their unique identifiers, avoiding false positives. For instance, only the flag associated with a submerged participant will activate, even if multiple flags are within close proximity.
The Captain's FOB serves as a versatile remote control for system management. The functional capabilities include raising and lowering the Smart Flag, adjusting the volume of the audible alarms emitted by the Smart Flag, sending critical danger signals, such as loud, long alarm bursts accompanied by flag waving, and establishing unique identifier-based interactions with other components, ensuring precise and reliable communication.
The Man Down Switch is an essential safety device designed for engine cutoff. It is physically installed on the watercraft to ensure mechanical reliability. It activates only when the captain falls overboard, cutting off the engine to prevent further danger. Although currently a wired device, it has the potential for future wireless functionality. Unlike other components, the Swimmer's FOB does not interact with the ECOS to prevent unintentional activation.
The swimmer's FOB device is specifically designed for participants. It is equipped with bidirectional RF and data transmission, allowing it to both send and receive signals and proprietary logic enabling processing of RF and data inputs to establish a relationship with other SMART components. It differentiates itself from other FOBs by having logical interactions with the Smart Flag, Captain's FOB, and other system components. It further ensures safety through accurate submersion detection that combines multiple mechanisms beyond RF signal interruption.
Each component and unit within a class in the system is assigned a unique identifier, enabling individualized interactions and precise coordination. This unique identification mechanism ensures that the system recognizes and responds only to its paired devices, effectively preventing false alarms. For example, in scenarios where multiple boats equipped with the system operate in close proximity, only the Smart Flag paired with the specific participant's FOB will activate upon submersion. This capability allows the system to establish logical relationships between devices, ensuring seamless communication even in complex environments with multiple users and watercraft. The unique identifiers not only enhance safety but also maintain the integrity of system operations by isolating interactions to specific, paired devices.
The system further employs a robust, multimodal approach to submersion detection, combining multiple mechanisms to ensure accurate and reliable responses. One method involves the interruption of RF signals, where a loss of communication between the FOB and other components indicates potential submersion. In addition, the system facilitates data exchange between the FOB and the Smart Flag to validate submersion events. Integrated sensors within the FOB further enhance accuracy by providing logical processing of various inputs, confirming submersion based on predefined criteria. This layered approach significantly reduces the likelihood of false positives and ensures timely activation of safety protocols.
The Smart Flag is a central signaling component that uses multimodal communication to enhance safety and situational awareness. It emits loud, adjustable audible alarms that effectively alert nearby individuals and watercraft to emergencies. Simultaneously, the flag raises and waves to provide a clear visual signal, indicating that a participant is in the water. The alarm volume is adjustable via the Captain's FOB, allowing customization based on the audience and environmental conditions. This combination of auditory and visual signaling ensures that the system effectively communicates the need for assistance, enhancing the safety of participants and surrounding watercraft.
The system's components are interconnected through advanced wireless communication protocols, including Wi-Fi and Bluetooth Low Energy (LE). This connectivity enables real-time data transmission and processing, allowing the components to interact dynamically and respond swiftly to changing conditions. Logical synchronization across all devices ensures that responses are coordinated and accurate. Additionally, the system integrates seamlessly with external platforms such as mobile applications and GPS devices, further extending its functionality. This interconnected network not only enhances the system's safety capabilities but also provides users with intuitive and convenient control over its features.
Safety and reliability are paramount in the system's design. Logical processing ensures that only the intended components activate during emergencies, preventing false positives and enhancing trust in the system. Redundancy in submersion detection mechanisms minimizes the risk of failure, providing a reliable safety net for participants. Furthermore, the use of unique identifiers for each component ensures precise interactions, even in environments crowded with multiple users and watercraft. These features collectively make the system robust and dependable, significantly improving safety outcomes during water sports activities.
The system's advanced features enable it to handle various scenarios effectively. In a wake surfing situation, if a participant falls into the water, their paired FOB detects the submersion and communicates with the Smart Flag, which raises and signals the surrounding area. The Captain's FOB can adjust the alarm volume to ensure the signal is clear and alerts nearby watercraft. In close-proximity operations involving two boats equipped with the system, the unique identifiers ensure that only the flag paired with the affected participant's FOB responds, avoiding unnecessary activation. Additionally, the system dynamically adjusts alarm volume and flag signaling based on environmental conditions and proximity to other watercraft, ensuring optimal safety in varying scenarios.
The system is designed with scalability and adaptability in mind, making it future proof. It has the potential for integrating a wireless ECOS (Man Down Switch) in future iterations, eliminating the need for physical installation. The system is also compatible with IoT platforms, enabling advanced data analytics and trend identification for continuous improvement. Further, the use of advanced materials and sensors enhances its performance, reliability, and functionality. This forward-thinking design ensures the system remains relevant and effective as technology and user needs evolve, setting a new standard in water sports safety and situational awareness.
The present invention will now be described with reference to the accompanying drawings which should be regarded as merely illustrative without restricting the scope and ambit of the present invention. Embodiments of the present invention will now be described with reference to
In an embodiment, the RTB 100 may be equipped with a surf or ski or recreational wake system for modifying a wake formed by the RTB 100 while travelling or towing through water. Advantageously, the wake system may enhance surf or ski or recreational wakes with or without supplemental ballast and thus it is possible to enhance wake with less watercraft lean. The wake system may include one or more water diverters such as a water diverter 106. Each water diverter may be adjustably mounted relative to the RTB 100 for deflecting water travelling past a transom 102 of the RTB 100. Broadly, the water diverters are movably mounted with respect to the transom 102. Although the illustrated embodiment shows the flaps mounted directly on the transom 102, one will appreciate that the flaps may be moveably mounted directly or indirectly to the transom 102. For example, the flaps and associated hardware may be mounted on a removable swim platform or other structure that is mounted on or adjacent to the transom 102. As also shown in
The data and visualization center may include a controller 402, a notification element 404, a memory 406, a communication interface 408, one or more sensors 410, a ballast 412, and a user interface 414. In an embodiment, the user interface 414 may include a button that corresponds to a relatively linear left-side surf wake, a button that corresponds to a relatively linear right-side surf wake, a button that corresponds to a relatively curved left-side surf wake, and a button that corresponds to a relatively curved right-side surf wake. Additional buttons may be included for selecting other wake types or other wake features (e.g., wake height, length, or the like). The user interface 414 may include other buttons for specified preset wake types. The user interface 414 may include user input elements (e.g., buttons) that allow the operator to adjust one or more aspects (e.g., wake height, length, steepness, etc.) of the wake. The user interface 414 may permit the operator to store the adjusted settings (e.g., in the memory 406) for later use. The controller 402 may be configured to adjust multiple features (e.g., water diverters, wedge, and/or ballast) based on the selection of a single wake-type button. The controller 402 may also adjust the ballast 412, as well as other wave shaping features such as trim tabs, watercraft speed, positions of the water diverters, or the like to produce the selected wake type. In some embodiments, the controller 402 may be configured to set the watercraft speed, or to present a recommended watercraft speed. In some embodiments, the controller 402 may set the watercraft speed upon the selection of the wake type. In some embodiments, the controller 402 may determine a recommended watercraft speed and may communicate (e.g., via a visual display or an audio speaker) the recommended watercraft speed to the operator (e.g., a driver). In some embodiments, the amount or distribution of the ballast can be changed by the controller 402 in response to a selection of a wave type by the operator. The ballast (e.g., water held in containers in the RTB 100) can be automatically moved from one side of the RTB 100 (e.g., right side) to the other side of the RTB 100 (e.g., left side) based on a selection that changes the surf or ski or recreational wake from one side to the other. The distribution of the ballast may be changed by the controller 402 based on a selection of a wake type by the operator. In response to the selection of the wake type, the controller 402 may automatically move ballast in the RTB 100 from the front to the rear or from the rear to the front of the RTB 100. In some embodiments, the controller 402 may consider both static variables (such as the type of tow watercraft) and dynamic variables (such as the depth of water, the number of passengers or participants on board, etc.) when setting the wake shaping features to achieve a specified wake type. Because the dynamic variables can have different values at different times, the controller 402 may be configured to adjust the wake shaping features differently at different times even when trying to achieve the same wake type. For example, the controller 402 may use less ballast 412 when more passengers or participants are on the RTB 100. In some embodiments, the controller 402 may be configured to adjust the wake shaping features on the fly, while the tow watercraft is moving, for example, to try and keep the wake consistent when dynamic variables change. For example, if the depth of water under the RTB 100 changes, the shape of the wake can also change, and the controller 402 may be configured to adjust the wake shaping features to compensate for the change in water depth to minimize the change in shape in the wake. In some embodiments, the RTB 100 may include the sensors 410 to sense and measure static or dynamic variables. For example, a water depth sensor may be included. A watercraft speed sensor may be included, especially where the operator is permitted to adjust the speed of the tow watercraft. The RTB 100 may include weight sensors for determining how much passenger or participant weight is on the RTB 100 and/or the distribution of the passenger or participant weight. Other sensors such as image, Lidar, Radar, Sonar, GPS sensors, or the like may be included in the RTB 100 for collecting the image data, Lidar data, Radar data, Sonar data, and GPS data of the participant and other personnel in and around the RTB 100. Using the Sonar, Lidar, Radar, Visual, and GPS data, the controller 402 may facilitates location tracking of all stakeholders and manage movements to safely operate tow watercraft recreational activities. The aim is to find the participant during the recreational activity, keep a track of the participant, detect one or more objectionable items in the vicinity of the participant, and avoid everything else. In case of any accidental events or mishap during the recreational activity, the operator (such as the driver or observer of the RTB 100) notifies or signals that the participant is down. Such notifications or signals may be communicated to rescue personnel or other watercrafts in its vicinity. Signaling may be achieved with multiple modalities. These include, but are not limited to, auditory, visual, mechanical, or any combination thereof.
In some embodiments, the user interface 414 may be configured to receive input from the operator regarding at least some of the dynamic variables. For example, the user interface 414 may allow the operator to specify a number of passengers or participants on the RTB 100 and/or the distribution of the passengers or participants on the RTB 100. In some cases, the memory 406 may store different settings for different participants, to account for the individual preferences. The user interface 414 may allow the operator to identify any specific participant. In some embodiments, settings and/or algorithms for particular wake shapes may be downloaded to the memory 406 from a remote source such as a data center. Further, the RTB may include a man down switch 416 and a tether 418. The man down switch 416 puts the watercraft's gear into neutral and if desired can lower the volume of the watercraft's radio when participant is submerged in the water. The tether 418 is a cord, fixture, or flexible attachment that serves to anchor a living or non-living object. It can also connect two movable objects, such as an item being towed by its tow. The tether 418 tether ensures safety and stability by preventing accidental separation from the boat or other fixed structures.
In an exemplary embodiment, a participant may hold on to the handle 506 of the tow rope 504 during the start of a towable run. The tow rope 504 may pull the participant up out of the water as the RTB 500A starts moving. In some instances, the tow rope 504 may interfere with the participant. For example, a participant may toss the tow rope 504 aside, but the flow of water may drive the tow rope 504 back towards the participant, which can cause the participant to fall and/or become tangled in the tow rope 504. When the participant releases the tow rope 504, a passenger or an observer in the RTB 500A may gather the tow rope 504 into the watercraft, which can be burdensome on the passenger or the observer. In some embodiments, the RTB 500A may include the retractable tow rope 504. The tow rope 504 can automatically retract (e.g., into a rope retracting chamber 502 of the RTB 500A) when the participant releases the tow rope 504. The rope retracting mechanism 508 may include a spool that is rotatable about an axis. The tow rope 504 may be coupled to the spool such that rotation of the spool in a first direction causes the tow rope 504 to wrap around the spool. Accordingly, rotation of the spool in the first direction can cause the tow rope 504 to be gathered into the rope retracting mechanism 508. Rotation of the spool in a second direction can release the tow rope 504 from the spool, which can allow the tow rope 504 to exit the rope retracting mechanism 508. The rope retracting mechanism 508 may include a spring coupled to the spool such that rotation of the spool in the second direction causes potential energy to build up in the spring. When the participant releases the tow rope 504, the tow rope 504 may be automatically retracted to the RTB 500A. In some embodiments, the tow rope 504 may be locked at a desired length. For example, one or more engagement features on the spool may be selectively engaged by one or more locking features, which can lock the spool in place, thereby preventing the spool from retracting the tow rope 504 and/or preventing the spool from releasing more of the tow rope 504. An actuator (e.g., a button or lever) may be configured to engage and/or disengage the locking features and the engagement features. To lock the tow rope 504 at a particular length, the tow rope 504 may be extracted to the particular length, and the actuator can be actuated to engage the locking features with the engagement features. Different participants may prefer to use different lengths of the tow rope 504. Different lengths of the tow rope 504 may be preferable for different recreation types and settings. Accordingly, in some embodiments, a maximum length of the tow rope 504 may be set such that the spool is impeded from rotating further in the second direction. The spool may be permitted to rotate in the first direction. Thus, in some embodiments, when the locking mechanism is activated, the length of the tow rope 504 behind the RTB 500A may only shorten and cannot increase in length. In some embodiments, the locking mechanism can include a ratchet system, e.g., which can include one or more pawls and one or more teeth. When engaged with each other, the pawls and teeth may be configured to ratchet in a first direction to allow the spool to rotate in the first direction to retract the tow rope 504 and to prevent rotation of the spool in the second direction.

In another embodiment, the RTB controlling device 702 further facilitates network coupling (i.e., communicative coupling) among various entities. For example,
The application server 1006 is a computing device, a software framework, or a combination thereof, that may provide a generalized approach to create the application server implementation. Examples of the application server 1006 include, but are not limited to, a personal computer, a laptop, or a network of computer systems. The application server 1006 may be realized through various web-based technologies such as, but not limited to, a Java web-framework, a .NET framework, a PHP (Hypertext Preprocessor) framework, or any other web-application framework. The application server 1006 may operate on one or more operating systems such as Windows, Android, Unix, Ubuntu, Mac OS, or the like. Various operations of the application server 1006 may be dedicated to execution of procedures, such as, but are not limited to, programs, routines, or scripts stored in one or more memory units for supporting its applied applications and performing defined operations. For example, the application server 1006 may be configured to collect the data from one or more data sources such as the RTB controlling device 1002 of the one or more RTBs. The collected data may be stored in the database server 1008. The database server 1008 may include suitable logic, circuitry, interfaces, and/or code, executable by the circuitry that may be configured to perform one or more data management and storage operations such as receiving, storing, processing, and transmitting queries, data, or content. In an embodiment, the database server 1008 may be a data management and storage computing device that is communicatively coupled to the application server 1006 or the mobile device 1004 via the network 1010 to perform the one or more operations mining, machine learning, social sharing, or the like.
The RTB controlling device 1002 may be configured to establish a network (such as the communication network 1010) among the devices or servers and other tow watercrafts via the one or more communication networks such as the communication network 1010. The communication network may include suitable logic, circuitry, interfaces, and/or code, executable by the circuitry, that may be configured to transmit queries, messages, data, and requests between various entities such as all other watercrafts in its vicinity. Examples of the communication network may include, but are not limited to, a Wi-Fi network, a light fidelity (Li-Fi) network, a local area network (LAN), a wide area network (WAN), a metropolitan area network (MAN), a satellite network, the Internet, a fiber optic network, a coaxial cable network, an infrared (IR) network, a radio frequency (RF) network, and a combination thereof. Various entities may be coupled to the communication network in accordance with various wired and wireless communication protocols, such as Transmission Control Protocol and Internet Protocol (TCP/IP), User Datagram Protocol (UDP), Long Term Evolution (LTE) communication protocols, or any combination thereof. In an exemplary embodiment, the communication network may be a controlled area network (CAN) bus. The CAN bus provides a common communication channel to various devices and components installed in the watercrafts for communicating with each other. The CAN bus is a message-based protocol that allows the various devices and components connected therewith to communicate with each other. In an embodiment, the RTB controlling device 702 may create or establish the network 1010 among the multiple participants, drivers, and/or tow watercrafts during recreation activities to provide an extended level of system operation, control, and optimization. For example, the acquired data and the generated trends may be discernment to the one or more tow watercrafts or the mobile devices of one or more drivers of the one or more tow watercrafts on the lake for facilitating ease of operation and control, along with the extended optimization. These data and trends may be rendered via one or more application portals (i.e., software applications) running on one or more respective devices such as mobile devices 1004 or tow watercraft devices. In addition to this, the present invention also discloses capturing, transferring, and using user data. The main purposes include data collection and mining, machine learning, social sharing, or the like
In an embodiment, the RTB controlling device 702 further facilitates big data analytics based on the data collected from the various sensors such as water depth, watercraft speed, weight, image, Lidar, Radar, Sonar, or GPS sensors. As the components of the recreational equipment become connected to the Internet, the big data analytics may be incorporated to identify trends that can be leveraged for further product optimization. The Sonar data, Lidar data, Visual data, and Position data may be collected and processed in real time to track movements in and around the watercraft and participant and automatically generate signals in case of one or more emergency situations.
In another embodiment, the RTB controlling device 702 further facilitates communication links between two or more entities (such as Watercraft to Watercraft, Watercraft to Shore, Watercraft to Satellite, Watercraft to Participant, Driver to Participant, Participant to Driver, Watercraft to Server, or the like) over the one or more communication networks.
As discussed above, there are 7 main components such as smart flag, captain's console, captain's FOB, swimmer's FOB, smart device application (App), SOS protocol, and man down switch. The first 6 components depend on the wireless communication (such as Wi-Fi, Bluetooth, IoT, etc.). The man down switch, which must be installed, puts the watercraft's gear into neutral and if desired can lower the volume of the watercraft's radio when participant is submerged in the water. The current range of the wireless communication from the FOB to the smart flag and caption's console is 200 meters (bit it has capability to upgrade to 480 meters) when in direct line of sight, which is the case with water sports. The direct line of communication acts as a wireless tether connecting the FOBs to the captain's console and the smart flag. When the Fobs are submerged in the water, the tether is broken, which then activates the console, the flag, the alarm, and the app. The smart flag activates rising into position and noting its GPS location. In addition to the activation, the flag has manual buttons for UP, DOWN, WAVE, and RESET functions. The smart flag is also capable of indicating its connection and the status of the FOBs, captain's console, the App. The captain's console activates both visual and auditory alarms, the Man down switch if installed, GPS location via the App, and the SOS protocol if the captain's FOB broke its tether. The SOS alarm triggers rescue protocol on the smart device via AIS, text, call for help etc. The captain's console will also mark GPS location when FOB tethers are broken. The captain's console has manual buttons for controlling functions of the flag, the man down switch, SOS protocol activation, and the connectivity to FOB's and App's on smart devices. The smart device App may be configured to alarm the captain when the swimmers is in the water along with their location. The location information may include location of the flag, the captain's console, and FOBs. The smart device App may provide status on the system, activate SOS protocol, and provide information and direction. The watercraft may include a kill engine or switch that is ignited to turn OFF/ground/neutralize the motor and propulsion system of the watercraft. Generally, the spring action within the kill engine or switch breaks the electric circuit of the engine ignition system, thereby turning OFF, or “killing” the engine of the watercraft. The kill switch is located at the ignition system and grounds it, thus turns OFF the motor but not the ignition system. The ignition system is capable of igniting after the grounding without any further human interaction.
The operation of the water sports safety system begins with the integration of all its SMART components, including the SMART FOBs, Smart Flag, Captain's Console, and Man Down Switch (ECOS), each programmed to perform specific safety functions while interacting seamlessly with other components. For example, during a recreational wake surfing session, the participant uses a Swimmer's FOB, which continuously transmits RF signals and data to establish a logical relationship with the paired Smart Flag and other system components. This FOB features unique identifiers, allowing it to interact only with its designated devices, ensuring no interference occurs from nearby watercraft with similar systems. As the watercraft operates, the system actively monitors the participant's status using the Swimmer's FOB. The FOB collects data from its onboard sensors and transmits it to the Smart Flag and Captain's Console. If the participant falls into the water, the FOB detects submersion through multiple mechanisms: an RF signal interruption, logical processing of sensor data, and data exchange with the Smart Flag. Once submersion is confirmed, the Smart Flag is automatically activated. The actuator within the flag housing raises the flag, while the integrated speaker emits an audible alarm. The Captain's FOB allows for remote control of the alarm volume, ensuring that the signal is audible without causing unnecessary disruption. Simultaneously, the Smart Flag uses its unique identifier to confirm it is responding to the correct FOB, preventing false alarms that might occur in a crowded environment. The Captain's Console also engages upon detecting a submersion event. It synchronizes with the Smart Flag and Swimmer's FOB to provide real-time updates, including the participant's GPS location. The console can relay this information to a connected mobile app, enabling additional safety features such as SOS alerts, notifications to nearby watercraft, or direct communication with rescue services. The captain can further use the console to manually override or adjust system functions, such as lowering the flag once the participant is safely recovered. If the captain falls overboard, the ECOS system comes into play. This Man Down Switch, connected physically to the watercraft, immediately cuts off the engine to prevent further movement. This safety measure operates independently of the other components to avoid accidental activation by the Swimmer's FOB. In future iterations, this system may also be implemented wirelessly, enhancing ease of installation and functionality. The system's advanced networking capabilities ensure consistent and precise operation. All components communicate via Wi-Fi and Bluetooth LE, enabling synchronized responses. For instance, if multiple participants are involved, each paired FOB interacts only with its designated Smart Flag and Console, ensuring no overlap in signaling. Moreover, the system dynamically adjusts to environmental conditions. In poor visibility or high-traffic areas, the alarm volume and flag motion can be amplified to ensure they are noticed by surrounding individuals and watercraft.
A specific scenario exemplifies the system's effectiveness: during a wake surfing event with two boats operating within 30 feet of each other, one participant falls. The paired Swimmer's FOB detects the fall and signals the corresponding Smart Flag to activate, while the other boat's system remains unaffected. This precision is achieved through the unique identifiers embedded in each device. The Captain's Console on the participant's boat provides real-time location data and updates, facilitating quick recovery. Additionally, the Smart Flag's adjustable alarm volume ensures that only those in proximity are alerted, preventing unnecessary disturbances. This interconnected and intelligent safety system revolutionizes water sports by combining precise technical capabilities with user-centric design. Its reliance on unique identifiers, logical interactions, multimodal detection, and networked communication ensures unmatched reliability, safety, and convenience, making it an indispensable solution for recreational watercraft activities.
