Description:FIELD OF THE INVENTION

[0001] The present invention relates to a wearable band for promoting child safety and well-being that enables real-time detection of hazardous actions, emotional distress, or dangerous surroundings for children, ensuring timely intervention, enhanced protection, and positive behavioral reinforcement.

BACKGROUND OF THE INVENTION

[0002] The monitoring and management of child behavior in various environments such as homes, schools, and playgrounds require accurate detection of risky actions, emotional distress, and exposure to potentially hazardous surroundings, along with timely and appropriate intervention to ensure the child’s safety and well-being. These devices for children aim to reduce caregiver response time, minimize the risk of accidents, and improve behavioral outcomes by offering real-time feedback and support. Precision in monitoring physiological and environmental data, combined with effective intervention, is essential for preventing harmful behavior, reinforcing positive actions, and ensuring compliance with safety standards. Poorly designed devices lead to missed warning signs, ineffective intervention, discomfort for the child, or even increased exposure to emotional or physical harm.

[0003] Traditionally, the monitoring and correction of unsafe or undesirable child behaviour have relied on manual supervision by caregivers, teachers, or guardians, who must constantly observe, interpret, and respond to a child’s actions based on judgment and experience. These conventional approaches require continuous attention and quick decision-making, which are physically and mentally demanding, especially in dynamic or crowded environments. Manual supervision methods are inconsistent, with a high risk of delayed responses, missed warning signs, or overcorrection, which lead to emotional distress or physical harm to the child. Additionally, the lack of real-time data and personalized intervention makes it difficult to effectively track behaviour patterns or reinforce positive habits. As a result, traditional methods fail to prevent risky behaviour, provide timely guidance, and ensure a safe and supportive environment tailored to each child’s specific needs.

[0004] CN109255934A discloses a child monitoring method and a wearable device, comprising: obtaining the distance from a child to a TV; comparing the distance with a safe distance, and if the distance is less than the safe distance, a prompt signal is sent to a caregiver; If the said distance is within a safe distance and the child's position remains unchanged, the viewing time will be counted; if the viewing time is greater than the specified viewing time, a prompt signal will be sent to the caregiver; if the child's position has changed, a prompt will be sent to the caregiver signal.

[0005] US9747770B1 discloses a child tracking device including a wrist watch lockable onto a child's wrist in operational communication with a remote monitoring receiver unit with a liquid crystal display (hereinafter “LCD”) screen and a remote mobile device, such as a cellular phone, via a software application to continuously track a child's location and to provide an alert in the event the child strays a pre-set distance from either the remote monitoring receiver unit or the remote mobile device or leaves a designated geographical zone.

[0006] Conventionally, many bands have been developed that are capable of child safety and behavior tracking. However, these bands are incapable of automating the real-time detection and intervention, requiring continuous manual supervision to respond to hazardous behavior or emotional distress. Additionally, existing devices lack the ability to provide personalized behavioral analytics, limiting their effectiveness in promoting long-term positive behavior. These devices are unable to prevent risky actions or guide the child away from dangerous situations, and do not offer adequate shielding from environmental threats or emotional stressors, reducing their overall utility and responsiveness in dynamic child-centered environments.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a band that requires to be capable of real-time monitoring, detection, and intervention to ensure child safety and well-being across various environments such as homes, schools, and playgrounds. The developed device should facilitate continuous tracking of a child’s physical, emotional, and environmental conditions while promoting positive behavior and maintaining a secure, adaptive, and engaging safety of the child.

OBJECTS OF THE INVENTION

[0008] An object of the present invention is to develop a band that is capable of continuously monitoring and detecting hazardous behaviors, emotional distress, and dangerous surroundings in children with high accuracy and in real-time, enhancing child safety across multiple environments.

[0009] Another object of the present invention is to develop a band that is capable of accurately detecting proximity to objects in the child’s surroundings, enabling timely alerts to prevent accidental contact with hazardous and unsafe items.

[0010] Another object of the present invention is to develop a band that is capable of monitoring physiological conditions of a child in real-time, enabling detection of irregular or potentially harmful muscle activity to ensure the child’s physical comfort and safety.

[0011] Another object of the present invention is to develop a band that is capable of detecting entry into prohibited or unsafe areas, enabling real-time alerts and preventive measures to ensure the child's safety.

[0012] Yet another object of the present invention is to develop a band that is capable of tracking and reinforcing positive behaviours in children via engaging animations and achievement badges, promoting long-term behavioural development and self-motivation.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0020] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0021] 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.

[0022] The present invention relates to a wearable band for promoting child safety and well-being that is capable of managing hazardous behavior, and environmental risks in children across home, school, and outdoor settings. The device facilitates preventing physical harm by providing timely interventions and shielding the child from unsafe objects or areas, while minimizing the risk of emotional stress.

[0023] Referring to Figure 1, an isometric view of a wearable band for promoting child safety and well-being is illustrated, comprising a C-shaped body 101 with multiple sliding units 102 and electromagnetic locking pins 103, and an inner lining of cushion padding 104 on the C-shaped body 101, a micro camera 105 integrated into the body 101, a microphone 106 on the body 101, a haptic vibration unit 107 on the body 101, an audio buzzer 108 on the body 101, a collapsible spherical scissor arrangement 109 arranged on the outer periphery of the body 101, a motorized gripper 110 mounted on an extendable L-shaped pole 111 via a motorized ball-and-socket joint 112, a holographic projector 113 mounted on a first motorized ball-and-socket joint 114, and an audio output module 115 on the body 101, an LED screen 116 arranged in the body 101, a lightweight supporting panel 117 attached to the collapsible spherical scissor arrangement 109 on the outer edge of the body 101.

[0024] The band disclosed herein comprises of a C-shaped body 101 with multiple adjustable segments for enabling adjustable fitting of the body 101 on a child’s wrist or hand. The C-shaped body 101 is preferably made up of lightweight, child-safe, and hypoallergenic materials such as medical-grade silicone, soft thermoplastic elastomers (TPE), or polyurethane composites to ensure flexibility, durability, and comfort during prolonged use.

[0025] The adjustable segments include multiple sliding units 102 that allows dynamic length adjustment of the C-shaped body 101 to accommodate varying wrist or hand sizes of children. The sliders 102 installed between the adjustable segments consist of a drawer arrangement which consists of a drawer that slides on rails integrated within the wearable band’s body 101. These rails provide a smooth and stable path for the extension and retraction of the adjustable segments. When the control unit 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 rails, enabling gentle restraint or protection of the child’s limb from hazardous contact.

[0026] A plurality of electromagnetic locking pins 103 is attached at the terminating points of the adjustable segments of the C-shaped body 101 for engaging with corresponding slots to securely lock the segments in place. Upon adjustment by the sliding units 102, a controlling unit actuates the electromagnetic locking pins 103. The electromagnetic locking pin 103 consists of an electromagnet, a ferrous metal plate, and a control arrangement. When energized, the electromagnet generates a magnetic field, inducing magnetism in the ferrous metal plate. This results in a strong attraction between the plate and the corresponding metal components within the adjustable segments of the C-shaped body 101. Upon activation, the magnetic force securely locks the adjustable segments in position, ensuring a stable and comfortable fit on the child’s wrist or hand.

[0027] An EMG (electromyography) sensor is integrated within the body 101 detecting and monitoring the electrical activity generated by muscle contractions in the child’s wrist or hand. The electromyography (EMG) sensor comprises electrodes embedded within the adjustable segments of the wearable band’s body 101, positioned to detect electrical signals generated by muscle contractions in the child’s wrist or hand. These electrodes transmit the bioelectric signals to integrated amplifiers that boost the weak signals for accurate measurement. Filters are applied to remove ambient noise and interference, resulting in a clean, enhanced signal representative of the muscle activity. This processed signal is then relayed to the control unit, which analyzes the data to monitor muscle tension and detect irregularities. Based on this analysis, the control unit engages or disengages the electromagnetic locking pins 103 to ensure optimal fit and user comfort.

[0028] An inner lining of cushion padding 104 is installed on the inner surface of the C-shaped body 101 to provide enhanced comfort and prevent irritation or pressure marks on the child’s wrist or hand during prolonged use. The padding 104 is made of soft, breathable, and hypoallergenic materials that adapt to the contours of the skin, ensuring a snug and gentle fit while maintaining ventilation and reducing the risk of discomfort.

[0029] A sensor array is integrated into the body 101 for detecting and monitoring various parameters related to the child’s physical activity, emotional state, and surrounding environment. The sensor array includes an electromyography (EMG) sensor, a flexible fiber-optic flex sensor, an infrared-based micro camera 105, an ultrasonic proximity sensor, a motion sensor, a thermal sensor, a microphone 106, and a GPS module which collectively provide real-time data for monitoring the child’s muscle activity, movements, surroundings, emotional state, and location.

[0030] The electromyography (EMG) sensor within the sensor array on the body 101 monitors the muscle activity and tension of the child’s wrist or hand. he electromyography (EMG) sensor comprises electrodes strategically embedded within the adjustable segments of the C-shaped body 101, along with amplifiers and filters. These electrodes detect the electrical signals generated by muscle contractions in the child’s wrist or hand and transmit them to the amplifiers, which enhance the signals for accurate measurement. Filters are then applied to remove any unwanted noise or interference. The resulting refined signal which is indicative of the muscle activity, is transmitted to the control unit for processing, enabling real-time monitoring of muscle tension and facilitating responsive adjustments to the electromagnetic locking pins 103 to ensure user comfort and safety.

[0031] The flexible fiber-optic flex sensor within the sensor array is embedded along the C-shaped body 101 to measure the curvature and bending of the child’s wrist or hand. The fiber optic flex sensor operates on the principle of detecting changes in light intensity within an optical fiber caused by bending or flexion of the child’s wrist or hand. The flexible fiber-optic flex sensor consists of an optical fiber core surrounded by a cladding layer, both made of materials with differing refractive indices.

[0032] When light is transmitted through the fiber, it undergoes total internal reflection at the core-cladding interface. Any deformation, such as bending or strain applied to the fiber due to wrist movements, causes microstructural changes, leading to shifts in the wavelength or intensity of the light signal reflected back along the fiber. These changes are detected by the sensor’s photodetector and interpreted by the control unit, enabling precise measurement of wrist curvature and motion for accurate monitoring of the child’s gestures and posture.

[0033] The infrared-based micro camera 105 within the sensor array is embedded in the body 101 of the wearable band to capture visual information of the child’s immediate surroundings. The infrared-based micro camera 105 consists of an infrared light source, an infrared camera sensor, and image processing protocol. The infrared light source emits non-visible infrared light towards the child’s surroundings, which is reflected back and captured by the camera sensor. As objects or individuals move within the child’s environment, the reflected infrared light patterns change, creating distinct images that are recorded by the sensor. These images are then processed by the image processing protocols to identify potential hazards, prohibited areas, or unusual activities. The processed data is sent to the control unit, which analyses the information to detect and respond to environmental risks, enhancing the child’s safety through timely alerts and interventions.

[0034] The ultrasonic proximity sensor within the sensor array is positioned on the C-shaped body 101 to detect the presence and distance of nearby objects relative to the child. The ultrasonic proximity sensor detects nearby objects by using high-frequency sound waves to measure distance. The ultrasonic proximity sensor consists of a transmitter that emits ultrasonic pulses and a receiver that captures the reflected echoes from surrounding objects.

[0035] When the ultrasonic proximity sensor is positioned on the body 101, it emits sound waves that travel through the air and reflect off nearby surfaces or objects in the child’s environment. The ultrasonic proximity sensor measures the time taken for the reflected waves to return. This time is directly proportional to the distance between the child and the detected object. By continuously calculating these distances, the ultrasonic proximity sensor provides real-time proximity data to the control unit, enabling detection of potential hazards and triggering appropriate safety responses, such as alerts, visual guidance, or deployment of physical barriers.

[0036] The control unit identifies behaviors such as consuming excessive snacks, tampering with fans or light bulbs, creating or throwing paper balls, littering, or pulling hair by detecting detailed visual information of the child’s hand movements and surrounding objects and precise distance measurements. The control unit continuously processes the combined data received from the infrared-based micro camera 105 and ultrasonic proximity sensors to detect and classify specific hazardous activities in real-time across environments including classrooms, playgrounds, and homes, enabling accurate real-time detection for timely interventions.

[0037] The motion sensor within the sensor array is embedded in the wearable band to detect and analyze the child’s gestures, movements, and posture. The motion sensor consists of infrared sensors and associated electronics integrated within the wearable band. The infrared sensors emit infrared radiation into the surrounding area near the child’s wrist or hand. When the child moves or gestures, the emitted infrared beams are reflected back to the motion sensor or absorbed differently based on the motion detected. The motion sensor captures changes in the reflected or absorbed infrared radiation, signaling the control unit that movement or a specific gesture has occurred. This data is processed by the control unit to recognize gestures, postures, or hazardous movements, enabling timely intervention and feedback to promote the child’s safety.

[0038] The thermal sensor within the sensor array detect the child’s body temperature as well as temperature variations in the surrounding environment. The thermal sensor is equipped with an infrared detector that absorbs infrared radiation emitted from the child’s body and surrounding environment, converting it into an electrical signal. This signal is then processed by an amplifier to enhance its strength. The amplified signal is forwarded to an analog-to-digital converter, which translates it into a digital format for analysis. The control unit interprets this digital data to identify temperature variations indicative of the child’s emotional state or environmental hazards, enabling timely detection of distress or unsafe conditions and triggering appropriate safety interventions.

[0039] The GPS (Global Positioning System) module is embedded within the C-shaped body 101 for continuously tracking the real-time location of the child. The GPS module receives signals from multiple satellites in the GPS constellation. Each satellite transmits a signal containing its position and the precise time of transmission. The GPS module calculates the distance from each satellite based on the time taken for the signal to reach the device embedded within the wearable band. By receiving signals from multiple satellites, the module performs trilateration to determine the exact position latitude, longitude, and altitude of the child. The control unit then receives these GPS coordinates and processes them to enable real-time location tracking, geo-fencing, and timely alerts for ensuring the child’s safety.

[0040] The GPS module works in synchronization with a geo-fencing module for detecting when the child enters or approaches predefined prohibited or dangerous areas. The geo-fencing module operates by creating virtual boundaries using GPS coordinates that define safe or restricted zones. The geo-fencing module consists of a geolocation processor that continuously receives real-time location data from the GPS module. This data is compared against stored boundary coordinates in the module’s memory. When the child’s location crosses these predefined boundaries, the module generates a trigger signal. This signal is sent to the control unit to initiate alerts, notifications, or safety interventions. The geo-fencing module maintains logs of boundary crossings for monitoring and analysis, ensuring precise location tracking and quick response to keep the child within safe areas.

[0041] The control unit is operatively connected with the sensor for analyzing the feedback data obtained from the sensors. The control unit continuously receives and analyzes real-time feedback data collected from multiple sensors including electromyography (EMG) sensors, flex sensors, micro cameras, ultrasonic proximity sensors, motion sensors, thermal sensors, microphone 106s, and the GPS module. The control unit is programmed to detect potentially hazardous behaviors or conditions by processing this sensor data and comparing it against a comprehensive, linked database that stores personalized child-specific information. This database includes critical parameters such as the child’s age, habitual behaviors, preferences, and any specific safety requirements.

[0042] An intervention assembly is integrated into the body 101 for initiating immediate and context-sensitive responses upon detection of hazardous behavior or environmental risks. The intervention assembly includes a haptic unit 107, audio buzzer 108, a collapsible spherical scissor arrangement 109, a grasping module, a holographic projector 113, an audio output module 115 and a deter module which collectively respond to hazardous behavior or unsafe conditions detected by the control unit.

[0043] The haptic vibration unit 107 within the intervention assembly deliver immediate tactile feedback in the form of vibrations upon detection of hazardous behavior or proximity to danger. The haptic vibration unit 107 comprises an eccentric motor coupled with an unbalanced mass that generates oscillatory motion when activated by the control unit. Upon receiving a signal indicating hazardous behavior or proximity to danger, the control unit energizes the eccentric motor, causing the unbalanced mass to rotate and produce vibrations. These vibrations are transmitted through the band’s body 101, delivering immediate tactile feedback to the child’s wrist or hand. The vibrational intensity and pattern are controlled to ensure effective and gentle alerts, encouraging the child to cease or modify unsafe actions without causing discomfort.

[0044] The audio buzzer 108 installed onto the body 101 works in synchronization with the haptic vibration unit 107 to provide immediate auditory feedback upon detection of hazardous behavior or unsafe conditions. The audio buzzer 108 operates on the principle of electromagnetic induction to generate sound vibrations for alerting the child. The audio buzzer 108 comprises an electromagnet coil, a metal armature, a contact point, and a diaphragm.

[0045] When an electric current is supplied by the control unit, the coil produces a magnetic field that attracts the armature towards it. This movement interrupts the electrical contact, causing the current to cease and the magnetic field to collapse. The armature then returns to its original position, re-establishing the contact. This rapid cycle repeats, causing the diaphragm attached to the armature to vibrate and produce an audible buzzing sound. The frequency and duration of the buzzer 108 sound are controlled by the control unit to provide distinct, age-appropriate alerts synchronized with the haptic vibration unit 107 for effective intervention.

[0046] A collapsible spherical scissor arrangement 109 is arranged on the outer periphery of the body 101 to form a physical barrier around the child’s wrist or hand. The collapsible spherical scissor arrangement 109 comprises multiple interconnected arms arranged in a crisscross pattern, each connected by pivot points to enable smooth extension and retraction. This arrangement 109 is powered by a hydraulic unit comprising a hydraulic pump, fluid reservoir, hydraulic cylinders, and control valves integrated within the wearable band. Upon detection of a hazardous proximity or behavior by the control unit, the hydraulic pump is activated to send pressurized fluid into the hydraulic cylinders. The cylinders are attached to the scissor 109 arms at pivot points which extend to push the arms outward, deploying the scissor arrangement 109 to form a protective spherical barrier around the child’s limb.

[0047] The collapsible spherical scissor arrangement 109 is attached to a lightweight supporting panel 117 on the outer edge of the body 101 for providing a sturdy and flexible base that allows quick deployment and retraction of the scissor arrangement 109 . The panel 117 is crafted from durable and lightweight materials to ensure minimal added weight while maintaining structural integrity. This arrangement allows the barrier to extend outward and form a protective shield around the child’s fingers, palm, or limbs, effectively preventing contact with hazardous objects like soil, uninsulated wires, switches, or sockets.

[0048] The panel 117 is securely fastened to the body 101 using magnetic clips, enabling easy attachment and detachment for maintenance. The magnetic clip consists of strong permanent magnets that aligns with corresponding metal plates or magnets on the body 101. When the panel 117 with the magnetic clips is brought close to the band, the magnetic force pulls and holds the panel 117 securely in place without the need for mechanical fasteners. This magnetic attraction allows for quick and effortless attachment and detachment. The magnets create a uniform magnetic field that ensures stable positioning, while the clip’s casing protects the magnets from physical damage and environmental factors, ensuring long-lasting performance and ease of use during regular maintenance or replacement.

[0049] The grasping module is arranged on the body 101 for gently restraining a child’s limb to prevent hazardous actions. Upon detection of an attempt to bypass the protective barrier, the control unit activates the grasping module. The grasping module includes a motorized gripper 110 mounted on an extendable L-shaped pole 111 via a second motorized ball and socket joint 112.

[0050] The L- shaped pole 111 within the grasping module extend for positioning of the motorized gripper 110. The L- shaped pole 111 operates through a pneumatic arrangement comprising an air compressor, air cylinder, air valves, and a piston, working together to extend and retract the pole 111. The pole 111 features a nested tube arrangement, with multiple concentric hollow tubes. The air cylinder, attached at the bottom of the nested tubes, houses a piston at the top. The air cylinder has an inlet and outlet valve connected to the compressor, which compresses air drawn from the surroundings. The pressurized air from the compressor enters the inlet valve, driving the piston forward. As the piston moves, the nested tubes are sequentially extended, lengthening the pole 111.

[0051] The motorized gripper 110 is attached with the L-shaped pole 111 for precise and controlled extension toward the child’s limb. The motorized gripper 110 consists of a DC motor that drives the movement of the gripper 110 arms via a mechanical linkage, which translates the motor’s rotational motion into precise, controlled opening and closing of the gripper 110. The motor’s operation is managed by the microcontroller, which sends signals to initiate movement, regulate speed, and ensure accurate positioning of the gripper 110 arms for gently grasping and redirecting the child’s hand or wrist away from the hazard.

[0052] The second motorized ball-and-socket joint 112 is installed between the motorized gripper 110 and the L-shaped pole 111 for providing multi-directional movement and flexible positioning. The second motorized ball and socket joint 112 is a coupling arrangement consisting of a ball joint securely locked within a socket joint, where the ball is able to move in a 360-degree rotation within the socket, providing the required rotational motion to the motorized gripper 110. The second motorized ball and socket joint 112 is powered by a DC (direct current) motor that is actuated by the control unit, enabling multidirectional movement and precise positioning of the gripper 110 for gentle restraint and redirection of the child’s limb during hazardous situations

[0053] A holographic projector 113 is mounted on a first motorized ball-and-socket 114 for providing multidirectional projection of guiding visuals, animations, or warnings. Upon detection by the micro camera 105 of the child approaching prohibited areas such as open flames, stairs, bodies of water, busy roads, sharp objects, or unstable structures, the holographic projector 113 projects visible guiding lines or animated characters to redirect the child to a safe path. The holographic projector 113 is a three-dimensional (3D) display that produces a three-dimensional guiding visual or animation for the child with the aid of a laser and a hologram. The holographic projector 113 works on the laser projection principle to display animated visuals illustrating the consequences of the behavior while sending real-time alerts with location and visual captured images to the user interface. The projector 113 captures a pre-programmed 3D image or animation, which is processed to create a virtual image suitable for guiding or instructing the child. The image is then projected onto a nearby surface using the laser. The laser projects the image at an appropriate angle through the first motorized ball-and-socket joint 114, depicting guiding visuals, animations, or behavioral cues to the child and allowing them to understand and respond to the guidance during hazardous situations.

[0054] The audio output module 115 is installed on the body 101 for delivering real-time verbal cues, alerts, or guidance to the child in response to detected hazardous behavior or environmental risks. The audio output module 115 comprises a speaker which is operatively connected to the control unit for converting electrical signals into audible sound signals. The speaker includes a diaphragm coupled to a voice coil positioned within a magnetic field. The voice coil generates a varying magnetic field upon receiving electrical signals from the control unit, causing displacement of the diaphragm. This displacement modulates the surrounding air to produce sound waves corresponding to the intended audio output. The generated audio is used to deliver real-time alerts, provide behavioural guidance, and play child-friendly voice prompts or safety instructions, assisting the child in understanding and responding to hazardous situations in an age-appropriate and effective manner.

[0055] The deter module is installed on the outer surface of the wearable band for deterring animals or unwanted interference near the child. When potential threats, such as stray animals are detected in the surrounding environment, the controlling unit activates the deter module. The deter module includes at least one piezoelectric vibrating unit and one or more LED (Light Emitting Diode) flash.

[0056] The piezoelectric vibrating unit in the deter module comprises a piezoelectric element, a compact mass, and a protective housing. The piezoelectric element, when electrically activated by the control unit, produces rapid mechanical oscillations or vibrations. These vibrations are amplified through the attached mass and transmitted through the wearable band. When the sensor array determines the presence of the potential animal threats in proximity to the child, the controlling unit activates the piezoelectric vibrating unit. When triggered, the piezoelectric element vibrates at specific frequencies intended to create an unpleasant or startling effect for nearby animals, deterring them from approaching the child.

[0057] Simultaneously, the LED (Light Emitting Diode) flash of the deter module emits bright light pulses to enhance the deterrent effect. When the sensor array detects the presence or approach of potential animal threats near the child, such as stray dogs or other intrusive animals based on inputs from the ultrasonic proximity sensor, infrared camera 105, and motion sensor, the controlling unit activates the LED (Light Emitting Diode) flash to emit high-intensity, pulsed light patterns to visually deter the animal and protect the child.

[0058] The LED (Light Emitting Diode) flash consists of high-intensity LEDs mounted on a compact circuit board within the wearable band, controlled by a dedicated driver circuit that regulates current to ensure optimal brightness and protect the LEDs from electrical damage. When the control unit detects an approaching animal threat through sensor inputs, it sends pulse-width modulation signals to the driver, causing the LEDs to emit rapid, strobing light patterns designed to startle and deter animals safely. The light is diffused through a durable translucent housing to maximize visibility while protecting the child’s eyes.

[0059] A reward module is arranged in the body 101 for encouraging and reinforcing positive behavioral patterns in the child by providing visual incentives and feedback. The reward module includes an LED (Light Emitting Diode) screen 116 integrated into the wearable band and is operatively connected to the control unit.

[0060] The LED (Light Emitting Diode) screen 116 functions by monitoring data from the sensor array to detect safe and desirable behavior such as avoidance of hazardous objects or compliance with safety prompts. The LED (Light Emitting Diode) screen 116 consists of a matrix of individually addressable LEDs arranged in a grid format, driven by a combination of row and column control lines. Each LED acts as a pixel that emits light when a forward voltage is applied across its terminals. The screen 116 includes a thin-film transistor (TFT), which regulates the flow of current to each LED based on the input signals received from the controlling unit.

[0061] The controlling unit sends digital instructions to the LED driver ICs, which sequentially activate specific rows and columns to illuminate the required LEDs, forming images, text, or animations. Brightness is controlled using pulse-width modulation (PWM), where the duty cycle of the voltage pulses determines the perceived intensity of each LED. The LED screen 116 is layered beneath a transparent protective panel and may incorporate colour filters or RGB LEDs to produce full-colour visual output. These visual outputs are dynamically updated in response to behavioural data or user interactions, allowing the reward module to display animations, badges, or feedback in real-time to engage and encourage the child.

[0062] The reward module continuously receives and analyzes feedback from the sensor array, which monitors the child’s activities and behaviors in real-time, focusing specifically on detecting avoidance of hazardous or harmful actions such as touching unsafe objects, entering prohibited zones, or displaying risky gestures. This behavioral data is processed by the control unit’s analytics protocols to assess patterns of safe conduct and improvements in the child’s compliance with safety guidelines. When the controlling unit detects sustained positive behavior or milestones, the reward module activates the LED screen 116 to display engaging and age-appropriate animations, congratulatory messages, or visual achievement badges that serve as immediate positive reinforcement. These visual rewards are motivating and encouraging, helping the child associate safety with fun and accomplishment. Additionally, the reward module transmits digital badges and progress reports wirelessly to a linked user interface accessible by caregivers or professionals, enabling them to track the child’s behavioral development remotely and provide additional support or rewards.

[0063] A user-interface inbuilt in a computing unit wirelessly linked with the device is accessed by a user to feed input and receive alerts and notifications. 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. The wireless communication between the microcontroller of the device and the computing unit is achieved through a communication module.

[0064] 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 device 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.

[0065] The database is configurable by caregivers or professionals through the secure user interface that is wirelessly linked to the wearable device’s control unit. This interface allows authorized users to input and update child-specific data such as age, known behavioural tendencies, preferences, medical conditions, learning styles, or common environmental triggers. The data can also include schedules, safe zones (e.g., home, classroom), and behavioural goals tailored to the individual child. Once this personalized data is stored in the database, the control unit uses it to analyse real-time sensor input more accurately and contextually. This enables the control unit to deliver age-appropriate, customized safety suggestions and interventions such as choosing the right type of animation, adjusting sensitivity thresholds for hazard detection, or selecting calming feedback patterns that align with the child's emotional needs.

[0066] The present invention works best in the following manner, where the band comprises of the C-shaped adjustable body 101 fitted with cushion padding 104 and electromagnetic locking segments, is comfortably worn around the child’s wrist. As the child engages in daily activities, the sensor array including EMG sensors, flex sensors, thermal sensors, motion sensors, the micro infrared camera 105, ultrasonic proximity detectors, microphone 106, and GPS module continuously monitors physiological, emotional, positional, and behavioural cues. This real-time data is transmitted to the control unit, which compares the feedback with the personalized database containing child-specific information like age, habits, and preferences. If hazardous or undesirable behaviour such as tampering with objects, entering dangerous zones, or emotional distress is detected, the intervention assembly is activated. The haptic unit or buzzer 108 provides immediate feedback, while the collapsible spherical scissor barrier or the gentle grasping module physically prevents the action. Simultaneously, the holographic projector 113 and audio module deliver visual and verbal guidance to redirect the child’s attention. In cases involving animals or dangerous objects, the deter module uses vibrations and flashing LEDs to deter threats. Positive behaviours are tracked by the reward module, which displays encouraging animations on an LED screen 116 and awards digital achievement badges to reinforce good conduct. All data and alerts are accessible to caregivers via the user interface on the connected computing device, which also allows customization of the child’s behavioural profile and safety parameters. Geo-fencing capabilities trigger real-time alerts if the child enters restricted areas, while the micro camera 105 captures and shares live visuals for prompt caregiver response, ensuring the holistic and responsive safety solution.
