Description:FIELD OF THE INVENTION

[0001] The present invention relates to an integrated toddler resting and monitoring system that provide toddlers with a safe and comfortable resting environment while enabling continuous monitoring of their health parameters, behavioral patterns, and surrounding environmental conditions and ensure that any irregularities or concerns are identified promptly, allowing caregivers to take timely action for proper care and medical assessment.

BACKGROUND OF THE INVENTION

[0002] The need for monitoring toddlers while resting arises from increasing concerns among parents and caregivers regarding the safety, health, and well-being of toddlers, especially in urban, fast-paced lifestyles where constant supervision is challenging. Traditional resting units lack capabilities to monitor vital health parameters, emotional cues, and environmental conditions. Caregivers often face difficulties in detecting early signs of illness, discomfort, or stress in toddlers, who are unable to effectively communicate their needs. Additionally, managing medical records, performing regular health checks, and ensuring optimal environmental conditions manually are time-consuming and prone to human error. These challenges highlight the need for a smart, responsive system that combines resting support with automated health and behavior monitoring in one unit.

[0003] Currently available devices for toddler care include baby monitors, wearable health trackers, smart cribs, and standalone environmental sensors. Baby monitors mainly offer audio and video surveillance but lack health monitoring features. Wearable health trackers monitor vitals but causes discomfort or skin irritation with prolonged use. Smart cribs provide rocking or soothing sounds but do not integrate emotional, environmental, or biochemical monitoring. Environmental sensors operate separately and do not interact with the child’s health status. These devices function in isolation without offering a unified platform for comprehensive health assessment, emotional analysis, and environmental control, making it difficult for caregivers to obtain a complete picture of the toddler’s well-being or respond proactively to potential health issues.

[0004] JP6382433B1 provides a method for relatively evaluating a health condition by comparing vital data of a childcare subject with past data and data of other childcare subjects. A plurality of sensor devices 400 for sensing the health status of a plurality of childcare subjects, a terminal device 300, and a server device 200 connected to the sensor device and the terminal device via a network 500 are provided. The sensor device measures vital data of the childcare subject for each first predetermined period and transmits it to the server device. The server device accumulates vital data of the childcare subject for the second predetermined period, and the vital data received from the sensor device is the same as the past vital data of the same childcare subject or other childcare subject. It compares with at least one of the vital data of a time slot | zone, and evaluates the health condition of a childcare subject based on the received vital data and the comparison result of the comparison unit. The terminal device outputs the health status of the evaluated childcare subject.

[0005] US5479932A discloses an apparatus for effectively and accurately monitoring the health of an infant is realized by simultaneously detecting large motor movement, heart beat and respiration of the infant, and sounding an alarm when an exacting combination of all three signals is not sensed. This integrated combination effectively eliminates false alarms inherent in prior art monitors. Preferably, a passive sensor is placed under, but not in direct contact with, a child for generating a voltage in proportion to the movement of the child. This signal is amplified, filtered and analyzed for the presence of large motor movement, heart beat and respiration. An alarm signal is sounded when all three are not present in the signal.

[0006] Conventionally, many systems are available in the market that facilitate resting and motion of the toddler. However, the cited inventions lack the capability to integrate health monitoring, emotional analysis, environmental sensing, and biochemical assessments into a single system, thereby failing to provide a comprehensive, automated solution for real-time toddler care, proactive diagnosis, and complete well-being management during rest.

[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 safe resting support while continuously monitoring vital health parameters, emotional states, and environmental factors, automatically responding to abnormalities, and maintaining an up-to-date health profile of the toddler in a unified and intelligent platform to ensure timely care and intervention.

OBJECTS OF THE INVENTION

[0009] An object of the present invention is to develop a system that allows toddlers to rest safely while continuously monitoring their health, behavior, and environmental conditions to ensure timely care and assessment.

[0010] Another object of the present invention is to develop a system that collects, analyzes, and stores real-time health data of a toddler to maintain accurate and up-to-date medical records.

[0011] Yet another object of the present invention is to develop a system that detects changes in a toddler’s physical, emotional, conditions and provides appropriate responses to ensure well-being.

[0012] 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.

[0021] The present invention relates to an integrated toddler resting and monitoring system that allows toddlers to rest safely while continuously monitoring their health, behavior, and environmental conditions, and that detects changes in their physical, emotional, and environmental states to provide appropriate responses for ensuring timely care, promoting well-being, and supporting a safe and responsive environment tailored to the toddler’s needs.

[0022] Referring to Figure 1, an isometric view of an integrated toddler resting and monitoring system is illustrated, comprising a mobile housing 101, a sliding door 102 provided with the housing 101, a layer of cushioning 103 provided in the housing 101, a biometric authentication unit installed with the housing 101, comprises a fingerprint sensor 104 and a facial recognition imaging unit 105, a plurality of openings 106 formed over the housing 101, each of the openings 106 closed by a hinged lid 107, a platform 108 extending from the housing 101, provided with an OCR sensor 109, a camera 110 installed in the housing 101, one or more microphones 111 installed in the housing 101, a plurality of compartments 112 provided with the housing 101, an articulated telescopic gripper 113 installed in the housing 101, an imaging means 114 installed in the housing 101, a soothing unit installed in the housing 101, comprises a plurality of multi-colour lighting elements 115, a plurality of vibration units 116 installed in the housing 101, a plurality of speakers 117 disposed in the housing 101, a fragrance unit 118 installed in the housing 101, a plurality of LEDs 119 (light emitting diodes) installed in the housing 101, a display unit 120 mounted on the housing 101 and a plurality of motorised omnidirectional wheels 121 attached underneath the housing 101 by means of telescopic rods 122.

[0023] The system disclosed in the present invention includes a mobile housing 101 designed to securely hold a toddler, providing a dedicated space for resting and monitoring. The housing 101 is ergonomically designed to ensure safety, with sufficient space to accommodate a toddler comfortably, while minimizing the risk of falls or injuries during rest or movement within the enclosed structure.

[0024] The system is equipped with a control unit that manages and coordinates all operational components integrated within the housing 101. The control unit serves as the central processing unit, receiving input and executing appropriate responses or storing data.

[0025] A plurality of motorized omnidirectional wheels 121 are arranged underneath the housing 101 to ensure ease of movement, particularly in clinical or home settings. The wheels 121 are attached underneath the housing 101 by means of telescopic rods 122, allowing the housing 101 to navigate in any direction and be repositioned with minimal manual effort, without disturbing the toddler inside.

[0026] The telescopic rods 122 are actuated by the control unit to elevate the housing 101 as required. The telescopic rods 122 are operated through the pneumatic actuator that is powered by the pneumatic unit associated with the system. The extension/retraction of the rods 122 work in the similar manner as mentioned above.

[0027] The motorized omnidirectional wheels 121 function by using the rotational power of a DC motor to drive the rollers of the wheel, which are positioned at a 45-degree angle to the central axis of the wheel. As the DC motor rotates the wheel, each roller moves independently to generate forces in multiple directions. The combination of these forces allows the wheel to move the housing 101 smoothly in any direction, including forward, backward, or sideways, without changing the orientation of the wheels 121.

[0028] A biometric authentication unit is installed with the housing 101. The biometric authentication unit comprises a fingerprint sensor 104 and a facial recognition imaging unit 105, allowing caregivers to securely unlock the housing 101 and prevents unauthorized access for enhancing the security and privacy of the toddler.

[0029] Firstly, the fingerprint sensor 104 is activated by the control unit to authenticate the biometric of the user. The fingerprint sensor 104 captures and records fingerprints by scanning the unique ridges and patterns on a user's finger. When a finger is placed on the fingerprint sensor 104, it uses optical means to create a high-resolution image of the fingerprint. When the finger is placed on a transparent surface above the fingerprint sensor 104, an internal light source illuminates the finger. The ridges and valleys of the fingerprint reflect varying amounts of light. The reflected light is captured by a high-resolution optical camera 110 beneath the surface, creating a detailed image of the fingerprint pattern. Image processing protocols enhance the captured image and extract key features to generate a digital fingerprint template. This template is then securely stored or compared for user authentication and verification.

[0030] Upon verifying the fingerprint of the user, the control unit activates the facial recognition imaging unit 105 to authenticate the facial detailed of the user. The imaging unit 105 comprises of an image capturing arrangement including a set of lenses that captures multiple images of the user’ face and the captured images are stored within a memory of the imaging unit 105 in form of an optical data. The imaging unit 105 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 control unit.

[0031] A sliding door 102 is provided with the housing 101, which enables convenient and secure access to position or remove the toddler. The door 102 is easy to operate and is lockable to ensure safety when the toddler is resting inside. Once the biometric authentication unit grant access to the user, the control unit actuates the door 102 to open, allowing the user to place the toddle in the housing 101 to rest.

[0032] The sliding door 102 operates through an electric motor connected to a gear arrangement and controlled by electronic signals from the control unit. When the motor is activated, a rotational motion is generated by the motor, which is transferred through gears or pulleys to move the door 102 along guided tracks. Limit switches are often used to define the fully open and closed positions, ensuring precise operation.

[0033] A cushioning 103 is installed along the interior surface of the housing 101 to provide a soft and comfortable resting area for the toddler. The cushioning 103 material is hypoallergenic, breathable, and gentle on the skin, ensuring both comfort and safety. The cushioning 103 supports the toddler’s body during extended rest periods, reducing discomfort and minimizing the risk of allergic reactions.

[0034] A plurality of openings 106 are strategically formed over the housing 101 to improve airflow and ventilation within the enclosed space, ensuring a fresh and breathable environment for the toddler during rest. Each opening is closable with a hinged lid 107, allowing to adjust the ventilation automatically. As the toddler is placed in the housing 101, the control unit actuates the hinge lids 107 to open the openings 106 for providing enhanced ventilation.

[0035] The hinged lids 107 use motors to control the movement of lids 107 allowing them to move in a converging or diverging manner. The hinges typically have a mechanical structure that allows for rotation or movement in multiple directions. The motor is connected to this hinge and provides the energy for the movement to adjust the angle or position of the attached lid. When the motor is activated, the hinges within move and this movement translates into the rotation or shifting of the lids 107 attached to the hinge. The motor makes the lids 107 converge by moving them closer together or diverge by moving them further apart.

[0036] A platform 108 is installed on the frontal portion of the housing 101, on which an Optical Character Recognition (OCR) sensor is mounted to scan and digitize the medical records relating to the toddler. The digitized records are then stored in a memory unit.

[0037] The OCR (Optical Character Recognition) sensor works by capturing an image of the hard copy medical report placed on the platform 108. The OCR sensor 109 uses a high-resolution camera 110 to scan the document and converting the printed text into a digital format. A text recognition protocol integrated with the OCR sensor 109 process the image to distinguish characters, numbers, and symbols, even from complex layouts. The extracted data is then digitized, structured, and stored in the memory unit.

[0038] A health module is paired with the control unit to create a health profile of the toddler, based on the scanned medical details. The digitized data from the OCR sensor 109 is then sent to the health module, where the data is processed to create or update the digital health profile of the toddler.

[0039] A plurality of pressure sensors are embedded along the inner bottom surface of the housing 101 to detect the distribution and intensity of pressure applied by the toddler’s body. The pressure sensors used herein are 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 sensors detect this change and converts it into an electrical signal that relates to the amount of pressure. This signal is then sent to the control unit to be processed to give a precise pressure reading.

[0040] In conjunction with the pressure sensors, a camera 110 is installed inside the housing 101 to capture head movements of the toddlers. The camera 110 comprises of an image capturing arrangement including a set of lenses that captures multiple images of the toddler and the captured images are stored within a memory of the camera 110 in form of an optical data. The camera 110 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 control unit.

[0041] Both data sources are sent to an analysis module connected with the control unit to identify any abnormalities in the toddler's posture. The analysis module compares this data against predefined posture templates or normal ranges stored in the system. In case, inconsistencies such as improper weight distribution, slouching, or unusual positioning are detected, they are flagged as postural abnormalities. The findings are then relayed to the control unit to be appended to the toddler’s health profile, and corrective actions or alerts may be initiated if necessary.

[0042] One or more microphones 111 are installed within the housing 101 to capture various vocalizations of the toddler, including crying, coughing, and breathing sounds. When the toddler makes vocalizations, the vocalizations made by the toddler are first captures by the microphone 111. These sound waves from the captured voice commands hit the diaphragm which vibrates back and forth in response to sound waves. The back and forth movement of the diaphragm is then transferred to a capacitor connected to the microphone 111 that converts the vibrations into an electrical signal that mirrors the pattern of the sound waves. The electrical signal is sent to the control unit for further processing.

[0043] The captured audio signals are fed into a vocalization analysis module that interfaces with the control unit. The vocalization analysis module uses pattern recognition protocols to detect potential respiratory issues. The pattern recognition protocols analyze the toddler’s vocalizations by using microphones 111 to capture sounds like crying, coughing, breathing, or babbling. These audio signals are processed through digital signal processing and converted into waveforms. The vocalization analysis module then compares the sound patterns against a trained database using features such as pitch, frequency, duration, and rhythm. A machine learning protocol integrated with the control unit helps to distinguish between normal and abnormal vocalizations, identifying potential issues like respiratory distress or discomfort and logs them into the health profile.

[0044] A plurality of compartments 112 are systematically arranged within the housing 101 to allow organized storage of diagnostic equipment required for toddler health assessment. The organized layout ensures easy access and efficient management of equipment, supporting quick retrieval during routine monitoring or diagnostic procedures.

[0045] An articulated telescopic gripper 113 is installed within housing 101 for extending, grasping, and delivering the required equipment to diagnose the toddler. The articulated telescopic gripper 113 consists of an articulated extendable linkage to position a gripper 113 equipped with the linkage. When the control unit actuates the gripper 113 to retrieve diagnostic equipment, the extendable linkage is extended to position the gripper 113 in proximity of the compartments 112.

[0046] The articulated extendable linkage is operated through a pneumatic actuator that is 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 linkage. The control unit controls the pneumatic valves to regulate the airflow and pressure, providing smooth and precise positioning of the gripper 113.

[0047] The articulated linkage contains several segments that are attached together by motorized joints also referred to as axes. Each joints of the segments contains a step motor that rotates and allows the articulated gripper 113 to complete a specific motion in translating the equipped gripper 113.

[0048] As the articulated linkage complete the specific motion, the control unit actuates the gripper 113 to grip the diagnostic equipment. The motorized gripper 113 uses actuators to open and close gripper jaws to allow the gripper 113 to hold diagnostic equipment., The gripper 113 is connected to a motor that generates motion which is transmitted to the linkages to move the gripper 113 in the required manner. Upon gripping, the control unit re-actuates the linkage to position the retrieved equipment in proximity of the toddler to perform diagnosis.

[0049] A plurality of position and force sensors are integrated with the gripper 113 to motion the position of the gripper 113 and force applied by the gripper 113. The position sensor used herein works through a reflective surface placed on the gripper 113. An optical encoder consists of a light emitter and a detector. As the gripper 113 moves, the reflective surface alters the angle at which light reflects back to the detector. The encoder measures these changes in light patterns, converting them into electrical signals that represent the gripper’s angular position. The control unit processes these signals to determine the gripper’s exact alignment with the surface.

[0050] The force sensor consists of components such as strain gauges to measure force through changes in electrical resistance when deformed due to applied pressure. As the user grips the handgrip, the force sensor captures the pressure applied and converts it into an electrical signal. This signal is then transmitted to the control unit, which interprets the force exerted.

[0051] The feedback from the sensors help to modulate the gripper's movement and applied pressure based on the sensed posture of the toddler from the camera 110 data, ensuring careful handling of tools around the toddler to prevent injury or discomfort.

[0052] An emotional state analysis unit is also installed within the housing 101 and is configured to analyze the emotional state of the toddler. The emotional state analysis unit utilizes an imaging means 114 to capture the toddler’s facial expressions. When the emotional state analysis unit is activated, the imaging means 114 captures multiple images of the toddler to analyze the emotional state.

[0053] The imaging means 114 comprises of an image capturing arrangement including a set of lenses that captures multiple images of the toddler resting the housing 101 and the captured images are stored within a memory of the imaging means 114 in form of an optical data. The imaging means 114 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 regarding the facial expression of the toddler, indicating emotional state from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the control unit.

[0054] A plurality of galvanic skin response (GSR) sensors are located along the inner bottom surface of the housing 101, to measure skin conductance. Along with the imaging means 114, the control unit activates the galvanic skin response sensors to measure skin conductance.

[0055] The galvanic skin response (GSR) sensors measure skin conductance by detecting changes in the skin's ability to conduct electricity, which increases with sweat produced during emotional or physiological arousal. The galvanic skin response sensor uses two electrodes placed in contact with the toddler’s skin, applying a low voltage between the electrodes. As emotional stress activates the sweat glands, even minimal sweating reduces skin resistance, leading to increased conductance. This change is measured in microsiemens and sent to the control unit.

[0056] Based on the inputs, an emotion module connected to the control unit, processes this data to determine whether the child is happy, stressed, or unwell. The emotion module fuses the data from the imaging means 114 and the GSR sensors to assess the toddler’s emotional condition. Using predefined thresholds and machine learning protocols, the emotion module classifies the child’s state as happy, stressed, or unwell.

[0057] A soothing unit is installed in the housing 101 to soothe the toddler. The soothing unit comprises a plurality of multi-colour lighting elements 115 to emit calming lights, vibration units 116 to provide gentle and soothing vibrations, speakers 117 to generate lullabies or white noise, and a fragrance unit 118 to release mild and toddler-safe scents.

[0058] Upon detection of a stressed or negative emotional state, the control unit activates the lighting elements 115 hanging from the ceiling of the housing 101 to emit calming lights. The lighting elements 115 consist of RGB lights that produce soothing light by adjusting the intensity of red, green, and blue LEDs 119 to create calming colour combinations. When stress or discomfort is identified, the control unit activates the lighting elements 115 to emit calming colours such as soft blue, gentle green, or warm pink.

[0059] The vibration units 116 are activated by the control unit to provide soothing sensations to the toddler. The vibration units 116 comprise 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 116 is translated to the toddler configured to calm the toddler.

[0060] The fragrance unit 118 is actuated by the control unit to emit fragrance for soothing the toddler. The fragrance unit 118 operates by using a small electric heating element to disperse fragrance from a liquid fragrance reservoir. When activated by the control unit, electrical current powers the heating element, which gently warms the liquid fragrance, causing it to evaporate and release aromatic vapors into the air. A pump is used to control the flow of liquid from the reservoir to the diffuser, ensuring a consistent release rate.

[0061] The speakers 117 are actuated by the control unit to generate lullabies or white noise. The speakers 117 works by converting the electrical signal into the audio signal. The speakers 117 consists of a cone known as a diaphragm attached to a coil-shaped wire placed between two magnets. When the electric signal is passed through the voice coil, a varying magnetic field is generated by the coil that interacts with the magnet causing the diaphragm to move back and forth. The movement of the diaphragm pushes and pulls air creating sound waves just like the electrical signal received and used to notify the user.

[0062] An environmental sensing unit is provided within the housing 101 to continuously evaluate environmental factors. The environmental sensing unit includes a temperature sensor, humidity sensor, and an air quality sensor to measure ambient temperature, moisture levels, and the purity of air to ensure the environment remains optimal for toddler health.

[0063] The temperature sensor operates by using a temperature-sensitive element, such as Resistance Temperature Detector (RTD), which changes its electrical resistance with temperature variations. As the temperature rises or falls, the resistance of the element changes accordingly. This change in resistance is converted into an electrical signal by the sensor's circuitry, which then processes the signal to determine the temperature.

[0064] The humidity sensor measures humidity by using a hygroscopic conductive material, often a polymer, whose electrical resistance changes with moisture absorption. As humidity levels increase, the conductive material absorbs moisture, causing its resistance to decrease. The sensor measures these changes in resistance and converts them into an electrical signal that represents the relative humidity. The final signal is then sent to the control unit.

[0065] The air quality sensor monitors the quality of air by detecting the presence and concentration of airborne pollutants such as particulate matter, carbon dioxide (CO₂), carbon monoxide (CO), volatile organic compounds, and other harmful gases. The air quality sensor uses metal-oxide semiconductor detection to measure these pollutants. The metal-oxide semiconductor detection measures air quality by using a heated metal-oxide surface that reacts with airborne gases. When pollutants like VOCs or CO are present, they alter the sensor's electrical resistance. This change is measured and analyzed to determine the concentration of contaminants in the air.

[0066] The data collected is then processed by the control unit to calculate an AQI value, indicating whether the air is clean or polluted.

[0067] An air conditioning unit is installed in the housing 101 to maintain conditions in the housing 101. The control unit compares the determined environmental conditions of the housing 101 against a pre-fed threshold range saved in a database. In case, the determined environmental conditions exceeds/recedes the pre-fed threshold range, the control unit activates the air condition unit to modulate temperature, humidity and air quality in the housing 101.

[0068] The air conditioning unit consists of several components working together to maintain optimal environmental conditions. A compressor circulates refrigerant through the system, enabling heat absorption and release. The evaporator coil absorbs heat from inside the housing 101, while the condenser coil releases it outside. A fan moves air across these coils to facilitate heat exchange. A thermostat monitors and regulates temperature, while a humidifier/dehumidifier adjusts moisture levels. Air filters trap dust and allergens, and purifiers neutralize VOCs and microbes. All components are controlled by the control unit, which receives input from temperature, humidity, and AQI sensors to adjust settings for toddler comfort and safety.

[0069] A biochemical analysis unit is integrated in the housing 101 to analyze saliva for identification of specific health markers. The analysis unit includes a robotic arm with a removable swab as the end effector of the robotic arm. The swab is configured to collect a saliva sample from the toddler’s mouth. The robotic arm contains several segments that are attached together by motorized joints also referred to as axes. Each joints of the segments contains a step motor that rotates and allows the robotic arm to complete a specific motion in translating the equipped swab. The swab further comprises of a pair of jaws hinged with each other by means of a bi-directional step motor. On actuation the step motor rotates and enables the opening/closing of the jaws of the swab for collecting the saliva sample.

[0070] A lab-on-chip module is located in the housing 101; the collected saliva sample is then transferred to the lab-on-chip module to perform various biochemical tests. The lab-on-chip module comprises a pH sensor for measuring saliva acidity, a glucose sensor for detecting sugar levels, and a salivary cortisol sensor for stress analysis.

[0071] The pH sensor measures the hydrogen ion concentration in saliva sample to determine the pH level using two electrodes to create an electrical circuit. The sensing electrode contains a substance with a known electric potential which is inserted into the solution being tested. The measuring electrode is made of a pH-sensitive glass that reacts to the hydrogen ion concentration in the solution. The glass membrane's buffer solution allows hydrogen ions to enter the membrane, creating a voltage potential that is measured by the sensor to calculate the pH value.

[0072] The glucose sensor measures sugar levels in saliva using an electrochemical detection method. The glucose sensor contains a glucose oxidase enzyme that reacts specifically with glucose molecules present in the saliva. When glucose comes into contact with the enzyme, it produces hydrogen peroxide as a byproduct. This chemical reaction generates an electrical current proportional to the glucose concentration. The generated signal is measured by electrodes and converted into glucose level readings through a signal processor.

[0073] The salivary cortisol sensor measures cortisol levels in saliva, which reflect the toddler's stress response. The sensor typically uses electrochemical detection methods. In electrochemical sensors, cortisol binding causes a change in current or voltage, which is measured by electrodes. The sensor’s output is processed by a signal processor and sent to the control unit, elevated cortisol levels indicate stress.

[0074] The data obtained from these biochemical tests contribute critical real-time insights and are appended to the health profile of the toddler for timely medical intervention.

[0075] A sense test module is configured with the control unit for evaluating the hearing and visual responsiveness of the toddler. The control unit directs the speakers 117 to emit specific sound patterns, while the imaging means 114 captures the child’s reaction. Simultaneously, an articulated laser light emits a focused beam, and the toddler’s eye movement is tracked using an Electrooculography (EOG) sensor. The combined data helps determine audio-visual sensitivity and development.

[0076] A plurality of LEDs 119 (Light Emitting Diodes) are integrated into the housing 101 to align with the circadian rhythm of the toddler. These LEDs 119 are regulated to change intensity and colour temperature throughout the day for supporting natural sleep and wake cycles to promote healthy development. The LEDs 119 are made from semiconductor materials which have properties that allow them to emit light. The LEDs 119 contains a p-n junction, where a p-type region is positively charged and an n-type region is negatively charged. When voltage is applied, electrons from the n-region move towards the p-region, and holes from the p-region move towards the n-region. As the electrons move across the p-n junction, they recombine with the holes. During this process, the electrons lose energy, and this energy is released in the form of photons (light).

[0077] A display unit 120 is mounted on the housing 101 for displaying the updated health profile of the toddler, along with diagnostic alerts, environmental data, and emotional analysis outputs, allowing caregivers to monitor the child without relying on separate devices. The display unit 120 operates by receiving processed data from the control unit, which analyzes input from the sensing module. This data is converted into a digital format and transmitted to the display via an integrated driver circuit. The unit, typically an LCD or LED screen, uses pixels controlled by electrical signals to visually represent the dielectric parameters.

[0078] The present invention works best in the following manner, where the toddler is placed inside the mobile housing 101 through the sliding door 102, the layer of cushioning 103 on the base portion of the housing 101 provides the comfortable resting surface. The system is activated through the biometric authentication unit comprising the fingerprint sensor 104 and the facial recognition imaging unit 105 for authorised access. Ventilation is maintained via the plurality of openings 106 closed with hinged lids 107. Medical records of the toddler are scanned using the OCR sensor 109 on the attached platform 108 and stored in the memory unit, which is processed by the health module configured with the control unit. The plurality of pressure sensors embedded along the inner bottom surface and the camera 110 monitor posture and head movements, feeding data into the analysis module. One or more microphones 111 capture vocalisations to detect respiratory issues via the vocalisation analysis module. The articulated telescopic gripper 113, guided by position and force sensors, fetches diagnostic equipment from the plurality of compartments 112. The emotional state is detected using the emotional state analysis unit, imaging means 114, and GSR sensors, with soothing actions initiated through multi-colour lighting elements 115, vibration units 116, speakers 117, and the fragrance unit 118. Environmental sensing and regulation are achieved through temperature, humidity, air quality sensors, and the air conditioning unit. The biochemical analysis unit uses the robotic arm and lab-on-chip module to evaluate saliva. The sense test module evaluates hearing and vision, and LEDs 119 regulate lighting per circadian rhythm. The display unit 120 shows the health profile, and motorised omnidirectional wheels 121 offer mobility.
