Description:FIELD OF THE INVENTION

[0001] The present invention relates to a swimming pool safety and monitoring system and method that automatically records users as they enter the pool and ensures safe and hygienic access by preventing unsafe entries, helping maintain user safety by providing injury prevention and drowning, uphold pool hygiene, and allow smooth, hassle-free entry without requiring manual supervision.

BACKGROUND OF THE INVENTION

[0002] Swimming pools are popular spots for recreation and exercise, but they come with serious safety risks like drowning, diving injuries, and accidents from unsafe behavior. Users often struggle with limited supervision, slow responses during emergencies, and the absence of real-time monitoring, which arises safety at risk. Pool operators also face the ongoing challenge of maintaining hygiene and keeping unauthorized or unwell individuals out of the pool. Relying on manual attendance and safety checks is time-consuming and prone to mistakes, making consistent oversight difficult. These issues point out the need for system that continuously watch over the pool to prevent accidents, manage access, and ensure a safe, clean environment for everyone.

[0003] Current swimming pool safety and monitoring solutions include surveillance cameras, lifeguard alert systems, wearable flotation devices, and automated pool entry systems. Surveillance cameras monitor visually but rely on human attention and does not act automatically in emergencies. Lifeguard alerts require manual response, which causes delays during critical situations. Wearable flotation devices help to keep individuals safe but do not track behavior or prevent unsafe actions in real time. Automated entry systems control access but usually do not integrate with activity monitoring, accident prevention, or hygiene management. These limitations show the need for a system that provides real-time monitoring, automatic safety measures, controlled access, and hygiene oversight to improve overall pool safety.

[0004] US6133838A discloses a system for monitoring a swimming pool to prevent drowning accidents includes sensing devices for providing electrical signals forming images of bodies immersed in the pool water. Appropriate hardware digitizes the resulting images, and the digital image data is compressed and stored at a series of times. Digitized images of a single body are compared at a series of times. The nature of a body, the path of the body and changes in the position of the body are estimated on the basis of the series of images; and an alarm is activated should the path or movement of the body being observed give cause for concern.

[0005] US5828304A discloses a pool monitoring system including a monitoring unit with a detection mechanism adapted to transmit an alarm signal upon the detection of a human falling within the body of water. Further provided is a timer deactivation mechanism having a first mode of operation during which an activation signal is transmitted, wherein the activation signal is transmitted only while the timer deactivation mechanism is maintained in the first mode of operation. The timer deactivation mechanism further has a second mode of operation initiated by the receipt of a timer deactivation signal via free space. The timer deactivation mechanism is further maintained in the second mode of operation during a time period inherent in the timer deactivation signal. Also included is a transmitter mechanism connected to the sound detection mechanism and timer deactivation mechanism. The transmitter mechanism is adapted to transmit via free space a remote alarm activation signal upon the receipt of the alarm signal from the sound detection mechanism coincident with the receipt of the activation signal from the timer deactivation mechanism. Lastly, a remote alarm unit is situated distant the monitoring unit and includes a timer selection mechanism adapted to transmit via free space the deactivation signal indicative of the predetermined time period. The remote alarm unit further includes a remote receiver mechanism adapted to generate an audible noise upon the receipt of the remote alarm activation signal via free space.

[0006] Conventionally, many systems are available in the market for monitoring the swimming pool safety. However, the cited inventions lack to provide real-time monitoring, preventing accidents, continuously supervising user behavior, and enforcing hygiene. As a result, gaps remain in responding quickly to emergencies, detecting unsafe actions, and managing the pool effectively, which limits their ability to ensure full safety and a secure environment.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a system that is required to be capable of providing real-time monitoring of users, automatic detection of unsafe actions, prevent accidents, manage access, and maintain hygiene. The develop system should allow timely intervention, improve user safety, reduce the risk of injuries, and ensure a secure and clean swimming pool environment for everyone.

OBJECTS OF THE INVENTION

[0008] The principal object of the present invention is to overcome the disadvantages of the prior art.

[0009] An object of the present invention is to develop a system that performs automatic inspection and attendance recording for users at the pool entry, ensuring efficient identification and streamlined access without manual intervention.

[0011] Another object of the present invention is to develop a system that prevents accidents and injuries by detecting unsafe actions, including diving, in the pool and taking timely measures to protect users.

[0012] Yet another object of the present invention is to develop a system that provides rapid and effective intervention during potential drowning incidents, ensuring timely assistance and enhancing user safety in the pool environment.

[0013] The foregoing and other objects, features, and advantages of the present invention will become readily apparent upon further review of the following detailed description of the preferred embodiment as illustrated in the accompanying drawings.

[0022] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0023] The present invention relates to a swimming pool safety and monitoring system and method that automatically checks and records users while entering the pool and making identification quick and access easy. In addition, the system herein also monitors for unsafe actions, like diving, and takes timely steps to prevent accidents, keeping users safe and the pool environment secure.

[0024] Referring to Figure 1 and 2, an isometric view of a swimming pool safety and monitoring system and method and a swimming pool associated with the system is illustrated, respectively comprising an entrance inspection and attendance kiosk 101 positioned at an access point to the pool, comprising a base platform 102, a first AI camera 103, a millimeter wave scanner 104 integrated into vertical walls of the platform 102, an image and UV reflectance-based inspection module 105, a wearable wristband 106, a vibration unit 107 embedded in a wrist band, a pool area monitoring module comprising a twin-axis motorized slider 201 carrying a second camera 202, a 3D holographic projector 203 mounted on the motorized slider 201, a safety arrangement module comprises, a motorized spool 204 with an extendable L-shaped link 205, a diving injury prevention arrangement comprising guiding rails 206 on vertical poles 207, a vertical plate 208 and motorized hinge joints 209, a cushioned landing platform 210 beneath the user and a drowning prevention arrangement comprising inflatable airbag structures 211 embedded within the pool base, hydraulic rods 212 connected to inflatable side plates 213.

[0025] The system disclosed in the present invention includes an entrance inspection and attendance kiosk 101 installed at the access point to the pool to manage entry and user verification. The kiosk 101 features a base platform 102 equipped with pressure sensors that detect the presence of a user when stepped onto the platform 102. The pressure sensor used here is a capacitive pressure sensor that works by measuring changes in capacitance. The pressure consists of two conductive members separated by a small gap. When pressure is applied, the gap between the member is changed, altering the capacitance. The sensor detects this change and converts it into an electrical signal that relates to the amount of pressure. This signal is then sent to an inbuilt microcontroller of the system to be processed to give a precise pressure reading.

[0026] A first AI camera 103 integrated with a 3D depth sensor captures high-quality facial images of the user and generates a depth map for accurate recognition. Once the presence of the user is confirmed, the microcontroller activates the first AI camera 103 to generate depth map for accurate recognition and verifies liveness by analyzing subtle pupil micro-movements, preventing spoofing attempts using photographs, videos, or masks, ensuring secure and reliable identity authentication.

[0027] The first AI camera 103 comprises of an image capturing arrangement including a set of lenses that captures multiple images of the user standing on the base platform 102 and the captured images are stored within a memory of the first AI camera 103 in form of an optical data. The first AI camera 103 also comprises of a processor that employ computer vision and deep learning protocols, including object detection, segmentation, and edge detection, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller.

[0028] In synchronization with the first AI camera 103, the microcontroller activates the depth sensor to detect pupil dilation micro-movements to verify liveness and prevent spoofing through photographs, videos, or masks. The depth sensor herein consists of an infrared emitter, a high-resolution photodetector array, precision timing circuitry, and a processing unit. The IR emitter projects modulated pulses toward the user’s eyes, and the photodetectors measure the return time for each reflection. Sub-millimeter depth accuracy enables detection of tiny pupil dilation micro-movements caused by natural eye reflexes. The processing unit analyzes depth variations over time to confirm physiological responses that is not replicated by photographs, videos, or masks. This real-time depth mapping ensures accurate facial authentication by distinguishing between live human eyes and spoofing attempts.

[0029] A millimeter wave scanner 104 is embedded within the vertical walls of the platform 102 to emit low-power millimeter wave signals that penetrate clothing and accessories to create a detailed 3D image of concealed items to identify prohibited objects such as sharp tools, food, beverages, or alcoholic substances. The millimeter wave scanner 104 consists of an array of transmitters and receivers embedded within the vertical walls of the platform 102. Each transmitter emits low-power millimeter wave signals, typically in the 30–300 GHz range, which penetrates clothing but reflect off concealed objects. The reflected waves are captured by the receivers and processed using high-resolution 3D imaging protocols. The millimeter wave scanner 104 further includes a signal generator, antennas, a signal processor, and shielding to prevent interference. During operation, the scanner 104 scans the user’s body, identifies prohibited items such as sharp objects, food, or alcohol.

[0030] A user-interface inbuilt in a computing unit wirelessly linked with the system is accessed by a concerned authority to provide input commands regarding monitoring of the swimming pool. The user interacts with the interface through a touch screen, keyboard, or other input methods available on the computing unit. The computing unit mentioned herein includes, but not limited to smartphone, laptop, tablet.

[0031] In case, prohibited items such as sharp objects, food, or alcohol is detected by the millimeter wave scanner 104, the microcontroller transmits an alert to the computing unit and alert the concerned authorities to restrict the entry of the individual into the pool. The wireless communication between the microcontroller of the system and the computing unit is achieved through a communication module.

[0032] The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the system is preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11 protocols. It connects to a network via an access point, converting digital data into radio signals. The module processes TCP/IP protocols for data exchange, interfaces with microcontrollers through UART/SPI, and ensures encrypted communication using WPA/WPA2 security standards for secure and efficient wireless connectivity.

[0033] An image and UV reflectance-based inspection module 105 scan the user’s exposed skin to detect abnormalities such as open wounds, rashes, or contagious skin conditions. The microcontroller analyzes the data in real time to confirm swimwear compliance and detect hygiene risks. The image and UV reflectance-based inspection module 105 comprises a visible-light camera, a UV LED illumination array, optical filters, and an image-processing unit. The visible-light camera captures high-resolution color images to assess swimwear compliance and skin appearance. The UV LEDs emit controlled ultraviolet light, while optical filters ensure only reflected UV wavelengths are detected, revealing abnormalities such as wounds, rashes, or contagious skin conditions through unique reflectance patterns.

[0034] The captured data is processed by the microcontroller that compare detected features against predefined hygiene criteria. In case any irregularity is found, the microcontroller generates a hygiene alert for pool staff over the computing unit.

[0035] An age estimation module is linked to the first AI camera 103 to analyze captured facial features and depth data to estimate the user’s age with high accuracy. The age estimation module generates a unique facial depth signature and assigns age-based swimming permissions, which are securely stored in an encrypted database. The age estimation module consists of a processor unit, memory storage, and an AI-driven facial analysis engine integrated with the first AI camera 103. In operation, the AI camera captures facial images and depth maps, which are processed by the age estimation module to estimate age using trained machine learning models. A unique facial depth signature is generated and paired with age-specific swimming permissions. The data is stored securely, enabling automated, repeatable access control and ensuring compliance with pool safety and age regulations.

[0036] A wearable wristband 106 is provided to verified users for continuous safety monitoring. The wristband 106 includes a pulse oximeter and PPG sensor to track oxygen levels and heart rate, along with an acoustic sensor to detect distress sounds such as shouting or splashing.

[0037] The pulse oximeter consists of a light-emitting diode (LED) array, preferably red (660 nm) and infrared (940 nm) LEDs, paired with a photodiode sensor. These components are enclosed in a small, durable housing that clips or straps to the skin, such wrist. During operation, the LEDs emit light through body tissue, and the photodiode detects the transmitted or reflected light. The microcontroller analyzes the varying absorption patterns of oxygenated and deoxygenated hemoglobin to calculate oxygen saturation (SpO₂) and pulse rate. The results are continuously updated, enabling real-time monitoring for health assessment and early distress detection.

[0038] The PPG (photo-plethysmography) sensor measure the cardiovascular parameters of the user by emitting light, usually from an LED, onto the skin, commonly at the wrist. As blood pulses through the vessels with each heartbeat, it absorbs varying amounts of light. A photodetector measures the amount of light that is either transmitted through or reflected by the tissue. These light fluctuations are converted into electrical signals, forming a waveform known as the PPG signal. By analyzing this signal, the microcontroller determines cardiovascular parameters such as heart rate.

[0039] The acoustic sensor consists of a diaphragm or membrane, a transducer element (such as a piezoelectric or MEMS microphone), and a signal processing circuit housed in a protective casing. The diaphragm vibrates in response to sound waves, including distress calls or unusual noises. These vibrations are converted by the transducer into electrical signals proportional to the sound’s frequency and amplitude. The built-in signal processor filters ambient noise and isolates relevant sound patterns. The processed data is then sent to the microcontroller, which analyzes it for predefined distress indicators, enabling timely alerts and intervention in safety-critical swimming pool monitoring applications.

[0040] An ultrasonic transmitter is integrated with wristband 106 that emits an age-specific ultrasonic signature for identification within the pool area. The ultrasonic emitter in the wristband 106 comprises a piezoelectric transducer, driver circuitry, and a protective housing. The piezoelectric element converts electrical signals from the control circuit into high-frequency mechanical vibrations, generating ultrasonic waves preferably above 20 kHz. These waves are modulated to carry an age-specific encoded signature, ensuring unique identification of each user in the pool area. The driver circuitry regulates frequency, amplitude, and modulation pattern. The poolside ultrasonic receivers detect these signals, decode the embedded age data, and communicate with the microcontroller for automated access control and safety monitoring.

[0041] A built-in vibration unit 107 alerts the user when they attempt to enter restricted zones, ensuring compliance with safety protocols. The vibration unit 107 comprises of an electric motor and an unbalanced weight. The weight is connected to the rotor of the motor. The rotation of the rotor of the motor due to the electric current causes the rotation of the unbalanced weight generating vibrations. The vibration from the vibration unit 107 is translated to the user.

[0042] A pool area monitoring module uses a twin-axis motorized slider 201 to position a second camera 202 with an integrated LiDAR sensor for wide coverage. The second camera 202 detects unsafe behaviors like running or diving in prohibited zones. The slider 201 involves two perpendicular rails: a main rail for horizontal movement and a secondary cross rail for vertical movement. The slider 201 installed on the edges of the pool consist of a sliding rail and a motorized slidable member connected to the sliding rail. The motorized slidable member is attached to the second camera 202 and sliding rail on both sides to make the second camera 202 slide. The slidable member is attached to a motor which provides movement to the member in twin-axis.

[0043] As the slider 201 moves, the microcontroller, activates the second camera 202 to detect unsafe behaviors. The second camera 202 integrated with the LiDAR sensor detects unsafe behavior in the pool by combining visual imaging with precise depth mapping. The LiDAR emits laser pulses that measure distances to surrounding objects and users, creating a 3D spatial map of the pool area. Simultaneously, the second camera 202 captures high-resolution video of user movements. The microcontroller analyzes the fused data to identify patterns such as running, diving in shallow zones, or entering restricted areas. By tracking body posture, motion speed, and location relative to safety boundaries, the microcontroller detects unsafe actions in real time.

[0044] Upon detection of unsafe behavior in the pool, the microcontroller activates a 3D holographic projector 203 on the motorized slider 201 to display real-time visual warnings to alert and guide users toward safe practices. The holographic projector 203 projects visual warnings by converting digital map data generated by the microcontroller into an interference pattern using coherent light. The interference pattern is then projected onto a surface and the light diffracted by the interference pattern reconstructs the 3D image of the warning. The resulting holographic image appears to be displayed on the surface, giving a three-dimensional view of the warning.

[0045] A safety arrangement module is designed to actively respond to detected safety events by deploying physical barriers or deterrents. A plurality of ultrasonic transmitters and receivers arranged along the walls of the pool generates and monitors high-frequency sound waves to detect movement of the user toward restricted zones. Ultrasonic transmitters and receivers consist of piezoelectric transducers housed in waterproof, corrosion-resistant enclosures for poolside installation. The transmitter converts electrical signals into high-frequency ultrasonic pulses, typically above 20 kHz, directed toward a target area. The receiver, also piezoelectric-based, detects reflected echoes when these pulses encounter a person. A control circuit measures the time delay between transmission and reception to calculate distance and detect movement. Multiple transmitters and receivers form a detection grid, enabling precise localization of users approaching restricted zones.

[0046] When the user is detected to be approaching restricted pool area, the system triggers the deployment of a physical barrier, effectively blocking entry. A motorized spool 204 mounted on an extendable L-shaped link 205, unwinds a flexible barrier plate wrapped over the spool 204. The spool 204 is actuated by the microcontroller to vertically unwrap the barrier plate in the depth of the pool forming the barrier to block access. The spool 204 consists of a DC motor that provides the power to unwind the barrier plate. The barrier plate is wound around the shaft of the spool 204 that is connected to the motor through a drive assembly to ensure the rotation of the shaft when the motor operates. One end of the barrier plate is fixed to the shaft, while the other end is free. When the spool 204 moves in an anti-clockwise direction, the barrier plate starts unwinding from the free end.

[0047] In synchronization with the actuation of the spool 204, the microcontroller actuates the extendable link 205 to extend horizontally in order to block the entire width of the pool. In a preferred embodiment of the present invention, the extendable link 205 is operated through an actuator that is pneumatically powered by a pneumatic unit. The pneumatic unit that includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension and retraction of the link 205. The microcontroller controls the pneumatic valves to regulate the airflow and pressure, providing smooth and precise positioning of the link 205.

[0048] In another embodiment of the present invention, the extendable link 205 is operated through an actuator that hydraulically powered by a hydraulic unit. The hydraulic unit comprises of a hydraulic pump, a hydraulic reservoir, a hydraulic fluid, hydraulic valves, and hydraulic cylinders. The hydraulic actuator utilizes pressurized fluid supplied by the hydraulic unit to create strong linear force, which drives the extension and retraction of the link 205. The microcontroller controls hydraulic valves to modulate fluid flow and pressure, ensuring controlled and stable movement of the link 205.

[0049] Yet in an embodiment of the present invention, the extendable link 205 is operated through an actuator that is electromechanically powered which convert electrical energy into precise mechanical motion. These actuators typically consist of electric motors coupled with mechanical components such as gears that drive the extension and retraction of the link 205.

[0050] A diving injury prevention arrangement arranged in the pool uses guiding rails 206 mounted on vertical poles 207 to position a vertical plate 208 with a drawer arrangement and motorized hinge joints 209. Upon detecting a dive into a shallow area, the microcontroller deploys a cushioned landing platform 210 beneath the user, reducing impact and preventing potential injuries.

[0051] The hinge joints 209 is actuated by the microcontroller upon detected detection of diving of the user into shallow water zone. When actuated, the cushioned landing platform 210 is deployed beneath the user. The hinge joints 209 preferably involves the use of an electric motor to control the movement of the hinge to deploy the cushion landing platform 210. The hinge joints 209 provides the pivot point around which the movement occurs. The motor is the core component responsible for generating the rotational motion. The motor converts the electrical energy into mechanical energy, producing the necessary torque that drives the hinge. As the motor rotates, the hinge orients the cushion landing platform 210 under the diver.

[0052] The guiding rail is actuated by the microcontroller, to position the diving injury prevention arrangement in alignment to the user diving in the shallow water. The guiding rail consist of a motorized slidable member connected to the rail. The motorized slidable member is attached to the vertical plate 208 and rail on both sides to make the plate slide. The slidable member is attached to a motor which provides movement to the member in a bi-directional manner.

[0053] In synchronization, the drawer arrangement is actuated by the microcontroller to extend the plate according to the required dimensions. The drawer arrangement consists of a drawer that typically slides on the rails 206 inside the vertical plate 208. These rails 206 provide a smooth and stable path for the compression and expansion of the vertical plate 208. The microcontroller actuates the drawer arrangement for expanding/compressing in order to increase or decrease the size of the vertical plate 208. When the microcontroller actuates the drawer arrangement, the motor starts rotating and the rotational motion is converted into linear motion through the use of gears. As the motor rotates, the drawer moves either outward or inward along the sliding tracks. This expansion and compression increase and decreases the size of the plates.

[0054] A drowning prevention arrangement features inflatable airbag structures 211 in the pool base and hydraulic rods 212 linked to inflatable side plates 213. The drowning prevention arrangement is controlled by the microcontroller, the microcontroller rapidly inflates and positions the airbag structures 211 to lift and guide a distressed swimmer toward the poolside, ensuring quick rescue and minimizing drowning risks.

[0055] The inflatable airbag structures 211 and the side plates 213 are equipped with an air compressor to inflate. As the distressed user is identified, the microcontroller actuates the air compressor to inflate the airbag structures 211 and the side plates 213. The inflation begins with the air compressor that draws in ambient air through a filter to remove impurities. The air compressor then compresses the air using a piston, increasing the pressure of the drawn air. The high-pressure air is either stored in a reservoir or directly supplied to the air bag structures and side plates 213, through an air hose connected to the valve stem of the bags. The valve stem opens to allow air to enter the air bag structure and side plates 213 and seals to prevent backflow.

[0056] Upon inflating the air bag structures and side plates 213, the microcontroller actuates the hydraulic rod 212 to retract and guide the user toward the poolside. The hydraulic rod 212 is powered through a hydraulic unit comprises of a hydraulic pump, a hydraulic reservoir, a hydraulic fluid, hydraulic valves, hydraulic cylinders and a pump. The hydraulic pump pressurizes the fluid from the reservoir and sends through the hydraulic hose to cylinder. The fluid pressure pushes against the piston, causing it to move. Because the piston is attached to the hydraulic rod 212, this movement extends the rod 212 outward from the cylinder. The rod 212 continues to extend as long as fluid is being pumped into the cylinder. When the rod 212 reaches the desired height, the pump stops, and the fluid remain in the cylinder for holding the rod 212 in place. To retract the rod 212, the hydraulic fluid is directed out of the cylinder and back to the reservoir. This causes the piston to move back into the cylinder, retracting the rod 212. This way the rod 212 extends/retracts to guide the user toward the poolside.

[0057] In an exemplary embodiment of the present invention, a method for swimming pool safety and monitoring begins with the inspection kiosk 101 verifying each user’s identity and liveness using facial recognition combined with depth mapping and micro-movement analysis to prevent spoofing. Once verified, the user is issued a smart wristband 106 that is uniquely linked to their profile and equipped with sensors for continuous vital sign tracking and location monitoring. As the user enters the pool area, a pool area monitoring module integrating AI cameras, LiDAR, and behavioral analysis works alongside the wristband’s sensors to observe swimming patterns, detect distress signals, and ensure compliance with safety rules. The collected data is continuously analyzed to identify safety events, such as signs of drowning, unsafe dives, restricted area entry, or medical distress. When such an event is detected, the system automatically activates a safety arrangement module, deploying physical intervention measures like barriers, cushioned landing platform 210, airbags, or hydraulic side plates 213 to protect the user while alerting staff for rapid assistance.

[0058] The present invention works best in the following manner, where the pressure sensors of the base platform 102 detects the presence of a user, thereby activating the AI camera and 3D depth sensor to capture facial images, perform depth mapping, and verify liveness through pupil dilation micro-movement analysis. Simultaneously, the millimeter wave scanner 104 integrated into the vertical walls scans for prohibited items, while the image and UV reflectance-based inspection module 105 checks for open wounds, rashes, and contagious skin conditions, generating hygiene alerts for pool staff if necessary. The age estimation module processes facial data to determine the user’s estimated age, updates the secured database with facial depth signature and permissions, and issues an authenticated wearable wristband 106 embedded with a pulse oximeter, PPG sensor, acoustic sensor, ultrasonic transmitter for age-specific signals, and a vibration unit 107 for restricted zone alerts.

[0059] In continuation, in the pool area, ultrasonic receivers detect the wristband’s signal to monitor permitted zones, while the pool area monitoring module on a twin-axis motorized slider 201 with a second camera 202 and LiDAR identifies unsafe behaviors and projects visual warnings through the 3D holographic projector 203. Upon detecting safety events, the safety arrangement module activates the motorized spool 204 with an extendable L-shaped link 205 carrying a flexible barrier plate and engages ultrasonic transmitters and receivers to block restricted access physically. If diving into a shallow area is detected, the diving injury prevention arrangement deploys a cushioned landing platform 210 via guiding rails 206, vertical plate 208, drawer arrangement, and motorized hinge joints 209. In a drowning incident, the drowning prevention arrangement inflates underwater airbag structures 211 beneath the distressed user and simultaneously extends inflatable side plates 213 using hydraulic rods 212 to elevate and guide the user toward the poolside.
