Description:FIELD OF THE INVENTION

[0001] The present invention relates to a cognitive support and healthcare system for dementia patients that is developed to provide care and assistance to individuals with cognitive impairments, specifically targeting those affected by conditions such as dementia. More particularly, the system continuously monitors the physical, emotional, and cognitive states of a user, and providing personalized care, safety, and wellness interventions in order to enhance the well-being of users, thereby assisting caregivers in managing the care of individuals with cognitive decline.

BACKGROUND OF THE INVENTION

[0002] People with dementia often struggle with daily tasks and feel overwhelmed or confused. Family members or caregivers may struggle to monitor the patient’s well-being constantly, especially when the patient’s condition worsens. Current healthcare systems primarily focus on providing basic monitoring, but they fail to adapt to the patient’s emotional and cognitive needs in real-time. Additionally, many traditional methods do not offer personalized care tailored to the patient’s current state, which is critical for improving their quality of life. There is also a lack of solutions that provide both physical and emotional support simultaneously, leaving caregivers with limited options to manage stress levels and prevent potential accidents.

[0003] Initially, dementia care focused on simple interventions such as creating structured routines and providing constant supervision. Early methods included basic tools like reminder clocks, memory aids, and therapeutic toys designed to stimulate the brain and alleviate stress. However, early equipment’s focused mainly on tracking physical activity or monitoring location but did not address other critical aspects of dementia, such as cognitive decline, emotional state, or changes in behaviour. As a result, they provided only a partial picture of a patient's condition. So, monitoring equipment’s, including GPS trackers and wearable alert systems are accessed. As these systems helped track patients' movements and alerted caregivers when a patient wandered, a common symptom in advanced stages of dementia. But these were limited to simple tracking functions and lacked the ability to assess the patient's emotional or cognitive state.

[0019] 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.

[0020] 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.

[0021] The present invention relates to a cognitive support and healthcare system for dementia patients that enable personalized support for individuals experiencing cognitive impairments, such as dementia, through the continuous tracking of their physical and mental well-being as well as providing up-to-date insights on their condition and recognizing early indicators of distress or health-related issues.

[0022] Referring to Figure 1 and 2, a perspective view of a cognitive support and healthcare system for dementia patients and an internal view of the system are illustrated, respectively, comprising a body 101 installed with plurality of motorized wheels 102, an artificial intelligence-based imaging unit 103 installed on the body 101, a microphone 104 is integrated with the body 101, a VR (Virtual Reality) headset 105 stored within a compartment 106 provided on the body 101, a speaker 107 installed on the body 101.

[0023] Figure 1 and 2 further illustrates a pincer assembly 108 mounted on the body 101, a Peaucellier linkage assembly 109 is mounted on a top of the body 101, a cushioning plate 110 attached with a free-end of the Peaucellier linkage assembly 109, a rotary disc 111 with multiple compartments, each holding a single dose of medicine, placed inside a cylindrical container 112 provided on the body 101, a spring-loaded flap 113 provided with the chute, multiple weights 201 are arranged on ceiling portion of the body 101 by means of a motorized slider 202.

[0024] The system disclosed herein comprising a body 101 which is equipped with a plurality of motorized wheels 102 (preferably 2 to 6 in numbers), enabling autonomous movement across a ground surface. The motorized wheels 102 facilitate smooth and efficient movement, ensuring that the body 101 travel across various terrains as needed.

[0025] The motorized wheels 102 are a circular object that revolves on an axle to enable the body 101 to move easily over the ground surface. For maneuvering the body 101 each of the wheels 102 need to rotate and which is governed by a hub motor fit in the hub of each of the wheels 102 that provides the rotation motion to the wheels 102 for maneuvering the body 101 on the ground surface.

[0026] A user interface is integrated within a computing unit, which is accessible by the caregiver of the user. This interface enables the caregiver to input personal and medical details of the user, which are stored in a user profile. The profile is created and maintained within a connected database, allowing the caregiver to update and reference vital information. The database is linked to the microcontroller, which processes and uses the information for various functions, ensuring that the user’s data is organized, readily available, and utilized for monitoring and providing appropriate care.

[0027] The body 101 is installed with an artificial intelligence-based imaging unit 103 that monitor surrounding environment. The imaging unit 103 disclosed herein comprises of an image capturing arrangement including a set of lenses that captures multiple images of the surroundings and the captured images are stored within memory of the imaging unit 103 in form of an optical data. The imaging unit 103 also comprises of the processor which processes the captured images.

[0028] This pre-processing involves tasks such as noise reduction, image stabilization, or color correction. The processed data is fed into AI protocols for analysis which utilizes machine learning techniques, such as deep learning neural networks, to extract meaningful information from the visual data which are processed by the microcontroller to monitor surrounding environment, including the user’s position, behavior, and emotional state by analyzing facial expressions, and body 101 language.

[0029] Synchronously, the microcontroller actuates a microphone 104 which is integrated with the body 101. The microphone 104 mentioned herein works as a transducer that converts sound waves into audio signal. The microphone 104 on receiving the input commands from the user converts the input signal into electrical signal and sends it to the microcontroller. The microcontroller processes the received signals in order to analyze the voice inputs of the user and upon analyzing the voice commands the microcontroller actuates the system and accordingly commands the system to carry out detection of early signs of cognitive decline.

[0030] A VR headset 105 is securely stored within a compartment 106 on the body 101 allowing it to be easily accessed by the user. When the microcontroller detects signs of distress or cognitive fluctuations in the user’s condition, the microcontroller activates a speaker 107 to suggest wearing the VR headset 105. Upon receiving the user’s response or when the user wears the headset 105, the microcontroller adjusts the VR environment according to the user’s cognitive state.

[0031] The speaker 107 receives an audio signal from the microcontroller based on the detected user condition (e.g., distress, cognitive state). When the microcontroller determines that the user requires intervention, the microcontroller generates an audio output signal. This signal is sent to the speaker 107, which transduces the electrical signal into sound waves. The speaker 107 emits sound based on the output provided, delivering clear audio instructions or prompts to the user. The speaker 107 adjusts the frequency and amplitude of the sound waves in response to the microcontroller's inputs, ensuring effective communication to the user in a given environment.

[0032] The Virtual Reality (VR) headset 105 herein displays photos and videos sourced from pre-fed content within a connected database. This content is specifically curated to evoke memories and stimulate emotional well-being in users exhibiting signs of cognitive memory loss. Upon detection of such signs by the system’s monitoring components, the microcontroller triggers the VR headset 105 to present personalized content designed to engage the user emotionally and mentally, thereby enhancing their cognitive state. This aims to improve the user's quality of life by promoting positive emotional responses and memory recall.

[0033] The VR headset 105 functions by immersing the user in a three-dimensional virtual environment. The VR headset 105 is equipped with screens positioned in front of the user’s eyes, offering a stereoscopic view. The user’s head movements are tracked by sensors within the headset 105, adjusting the displayed content to match the direction of their gaze. As the microcontroller detects signs of cognitive decline, the VR headset 105 adjusts its display to show relevant content such as familiar photos or videos from the user’s past, facilitating memory recall and emotional stimulation.

[0034] A wearable band 301, which is intended to be worn over the user’s head, incorporates a sensing module that includes a pulse sensor 302 and an EEG (Electroencephalography) sensor 303 to monitor the user’s heart rate and brain activity. Additionally, the module integrates an accelerometer 304 and a gyroscope 305, which are responsible for detecting movement and identifying falls. The data collected from these sensors is continuously transmitted to the microcontroller. This allows for real-time monitoring of the user’s health and physical condition, enabling the system to provide personalized adjustments to the care and support provided to the user (as shown in figure 3).

[0035] The pulse sensor 302 detects the user’s heart rate by emitting light through the skin using a light-emitting diode (LED). The pulse sensor 302 measures the amount of light reflected back to a photodetector, which fluctuates as the blood pulses through the capillaries. The microcontroller processes these fluctuations, determining the user’s heart rate based on the time intervals between each pulse. The pulse sensor 302 continuously monitors this data, sending the data to the microcontroller for real-time tracking of the user’s heart rate.

[0036] The EEG (Electroencephalography) sensor 303 records electrical activity in the brain by placing electrodes on the user’s scalp. These electrodes detect voltage changes resulting from the brain’s neural activity. The sensor 303 amplifies these signals and sends them to the microcontroller for analysis. The microcontroller processes the brainwave patterns, detecting specific states such as alertness, relaxation, or cognitive decline, which help in assessing the user's mental condition and health.

[0037] The accelerometer 304 detects motion and changes in position by measuring acceleration forces acting on the user’s body. The accelerometer 304 contains microelectromechanical systems (MEMS) that sense movement along the X, Y, and Z axes. When the user moves, the accelerometer 304 generates corresponding electrical signals that are transmitted to the microcontroller. These signals are processed to determine the speed, direction, and intensity of the user’s movement, allowing the microcontroller to track physical activity or detect any abnormal movements, such as falls.

[0038] Further the gyroscope 305 measures the angular velocity of the user’s movements by detecting rotation along different axes. Using sensors that detect the Coriolis effect, the gyroscope 305 senses changes in orientation and direction. The data is sent to the microcontroller, where the data is analyzed to track the user’s posture, balance, and rotational movements. This information is crucial for identifying imbalances, detecting falls, or assessing the user’s ability to move and navigate independently.

[0039] A pincer assembly 108 is mounted on the body 101 via a supporting link, comprising two arms made of cushioned padding. These arms are designed to deploy automatically upon detection of a fall. When the microcontroller detects an abnormal movement indicative of a fall via imaging unit 103, the supporting link activates the pincer arms, which move outward to surround the user’s lower body. The cushioned padding ensures that the support provided is gentle and does not cause discomfort, stabilizing the user and minimizing the risk of injury.

[0040] Upon detection of a fall, a signal is sent to activate the motorized actuators connected to the supporting link of the pincer assembly 108. These actuators deploy the two arms, which are cushioned with soft padding. The arms extend outward, forming a protective barrier around the user’s lower body. The cushioning ensures that the support is both gentle and firm, stabilizing the user’s body and preventing further injury. Once the fall is addressed or the user regains balance, the microcontroller retracts the pincer arms back to their resting position, ready for subsequent use if necessary.

[0041] Simultaneously, a Peaucellier linkage assembly 109 that is affixed to the upper portion of the body 101, comprising an assembly of interconnected arms and pivots, with a ball-and-socket joint integrated at one end, gets actuated by the microcontroller. Upon detecting a fall through the imaging unit 103, a signal is transmitted to the Peaucellier linkage assembly 109. This activates the linkage assembly 109, allowing the assembly to pivot and adjust the position of a cushioning plate 110 attached to the free end of the linkage. The plate 110 moves dynamically and aligns underneath the user’s head, ensuring protection from potential impact, thereby minimizing the risk of injury to the user's head.

[0042] The Peaucellier linkage assembly 109 operates based on the principle of converting rotational motion into linear motion. The linkage assembly 109 consists of a set of rigid bars, where a specific configuration of these bars enables the transformation of the rotational input into precise linear output. When a fall is detected by the imaging unit 103, an actuator connected to the linkage assembly 109 is activated. The bars within the Peaucellier linkage assembly 109 are arranged so that as the actuator moves, the motion is transferred across the linkage structure, resulting in the linear movement of the free end.

[0043] The free end of the linkage assembly 109 is attached to the cushioning plate 110. As the linkage assembly 109 moves in response to the actuators motion, it translates the rotational input into a downward motion of the cushioning plate 110. This downward motion positions the cushioning plate 110 directly underneath the user’s head. This ensures that the cushioning plate 110 is accurately positioned to absorb the impact of a fall and protect the user’s head from injury.

[0044] The motorized ball and socket joint mentioned here consists of a ball-shaped element that fits into a socket, which provides rotational freedom in various directions. The ball is connected to a motor, typically a servo motor which provides the controlled movement. The linkage assembly 109 is attached to the socket of the motorized ball and socket joint, the microcontroller sends precise instructions to the motor of the motorized ball and socket joint. The motor responds by adjusting the ball and socket joint and rotates the ball in the desired direction, and this motion is transferred to the socket that holds the linkage assembly 109. As the ball and socket joint move, it provides the necessary omnidirectional movement to the linkage assembly 109.

[0045] A plurality of weights 201 (preferably 2 to 6 in numbers) arranged on the ceiling portion of the body 101, which are connected to a motorized slider 202. The motorized slider 202 is dynamically controlled and actuated by the microcontroller, allowing for precise movement and adjustment of the weights 201. The microcontroller continuously monitors the user's movements and body position, utilizing real-time data from accelerometer 304 and gyroscope 305 to determine the optimal distribution of weights 201 required for maintaining balance and stabilizing the body 101.

[0046] Based on this data, the microcontroller actuates the motorized slider 202 to shift the weights 201 accordingly, ensuring proper support and stabilization of the user’s body during various activities or movements. The slider 202 consists of a pair of sliding rail fabricated with grooves in which the wheel of a sliding arrangement is positioned that is further connected with a bi-directional motor via a shaft. The microcontroller actuates the bi-directional motor to rotate in clockwise and anti-clockwise direction that aids in rotation of shaft, wherein the shaft converts the electrical energy into rotational energy for allowing movement of the wheel to translate over the sliding rail by a firm grip on the grooves. The movement of the slider 202 results in translation of the weights 201 in view of balancing the body 101 while stabilizing the user.

[0047] A rotary disc 111 equipped with multiple compartments, each containing a single dose of medication. This disc 111 is positioned within a cylindrical container 112 mounted on the body 101. A dispensing chute is located at the bottom of the container 112, enabling the release of the medication. A stepper motor is integrated with the disc 111, enabling controlled rotation at scheduled intervals. The stepper motor is activated by a microcontroller, which ensures that the disc 111 rotates in a precise manner, aligning the correct compartment with the dispensing chute.

[0048] Once the correct compartment is aligned, a spring-loaded flap 113 at the chute is triggered, releasing the designated dose of medication. This ensures that only the accurate dose is dispensed, while also preventing accidental dispensing of additional doses. The stepper motor operates through a sequence of electromagnetic pulses, where each pulse rotates the motor shaft by a specific angle, known as a step. In the context of the rotary disc 111, the stepper motor is controlled by a microcontroller to rotate the disc 111 at scheduled times. The motor’s precise movement ensures that the correct compartment aligns with the dispensing chute. The motor’s precise control prevents over-rotation or misalignment, ensuring that only the compartment containing the correct dose of medication is positioned for release. The motor continues to rotate in discrete steps until the correct position is reached.

[0049] The spring-loaded flap 113 is positioned at the dispensing chute and functions by utilizing the tension stored in the spring to regulate its opening and closing. When the rotary disc 111 aligns the correct compartment with the chute, the spring-loaded flap 113 is activated. The tension in the spring is overcome when the correct compartment’s contents are aligned with the chute. The flap 113 then opens, allowing the prescribed dose of medication to flow through. After the dose is dispensed, the spring pulls the flap 113 back to its closed position, preventing further release of medication until the next scheduled dispensing cycle.

[0050] The microcontroller dynamically adjusts the difficulty level of cognitive games according to the user's cognitive abilities and age. For individuals in the early stages of dementia, the system presents more complex tasks to engage and challenge their cognitive functions. In contrast, for users in the later stages of dementia, the microcontroller simplifies the tasks, incorporating additional visual and auditory cues to aid in task completion. This ensures that the cognitive games remain relevant and beneficial to the user’s specific condition, providing an optimized experience that supports cognitive health at various stages of dementia.

[0051] The imaging unit 103 herein continuously track and monitor the user’s location, ensuring that any movement toward a restricted or potentially hazardous area is promptly detected. Upon identifying such an approach, the microcontroller activates both audible and visual alerts, directing the user away from the unsafe zone. Simultaneously, caregivers are notified of the user’s proximity to danger, enabling them to take necessary actions to prevent any potential harm. This functionality is integral in ensuring the user’s safety by providing real-time alerts and facilitating proactive intervention by caregivers.

[0052] Further the microcontroller collects and analyze real-time data regarding the user's health, cognitive state, and behaviour. This data is then displayed through computing unit, offering caregivers and family members detailed reports on the user's condition. In the event of detecting any unusual activity or medical concern, such as falls or irregular heart rate, the microcontroller promptly generates alerts. These alerts are transmitted to designated caregivers or family members, ensuring that any significant changes in the user's health status are communicated immediately.

[0053] In an embodiment of the present invention the system incorporates a boundary-detection arrangement that continuously monitors the patient's proximity to restricted or unsafe areas. Upon the patient approaching such a boundary, the microcontroller activates an alert, such as an audible voice prompt (e.g., “Please stay out of the kitchen for your safety”), to warn the patient. If the patient persists in moving toward the restricted area, the microcontroller employs an intervention assembly that gently redirects the patient away from the danger zone. In addition to this, the microcontroller notifies designated caregivers, alerting them to the patient's potential entry into a hazardous area, thereby facilitating timely caregiver intervention to prevent harm or accidents. This ensures both the patient's safety and continuous monitoring of their movement in real-time.

[0054] In another embodiment of the present invention the system is equipped with an integrated video calling system, which allows the patient to initiate video calls effortlessly using an intuitive, AI-driven interface. The microcontroller provides clear, step-by-step guidance to the patient, assisting them in making a call, sending a message, or connecting with loved ones. This feature is designed to be user-friendly, ensuring that patients easily stay in touch with family and friends despite any cognitive challenges. By facilitating communication, the system helps reduce feelings of isolation, promoting emotional well-being and enhancing the patient’s connection with their social network.

[0055] Moreover, a battery is associated with the system for powering up electrical and electronically operated components associated with the system and supplying a voltage to the components. The battery used herein is preferably a Lithium-ion battery which is a rechargeable unit that demands power supply after getting drained. The battery stores the electric current derived from an external source in the form of chemical energy, which when required by the electronic component of the system, derives the required power from the battery for proper functioning of the system.

[0056] The present invention works best in the following manner, where the body 101 as disclosed in the invention is installed with plurality of motorized wheels 102 for autonomous movement of the body 101 on ground surface. The artificial intelligence-based imaging unit 103 continuously monitor surrounding environment, including the user’s position, behavior, and emotional state by analyzing facial expressions, and body language. Then the microphone 104 receives speech commands of the user, to detect early signs of cognitive decline. The VR (Virtual Reality) headset 105 stored within the compartment 106 provided on the body 101. Afterwards the microcontroller via the speaker 107 suggests the user to wear the VR headset 105 when signs of distress are detected, and accordingly the microcontroller adjusts VR environment based on user’s cognitive state to provide calming and mentally stimulating environment. Also, the VR displays photos and videos from user’s past, using pre-fed content provided on the database to evoke memories and improve the user’s emotional well-being, when signs of cognitive memory loss are detected. The wearable band 301 associated with the system adapted to be worn over head portion of user. The sensing module detects vital physiological parameters of the user. The pincer assembly 108 consisting of two arms fabricated with cushioned padding that deploy to surround the user’s lower body upon detecting the fall, providing gentle support to stabilize and prevent injury. And the Peaucellier linkage assembly 109 connected to the ball and socket joint. Upon detecting the fall to position the cushioning plate 110 attached with the free-end of the Peaucellier linkage assembly 109 underneath the user’s head portion to protect the user’s head from impact. Multiple weights 201 are arranged on ceiling portion of the body 101 by means of the motorized slider 202 that provide optimal translation to the weights 201 in view of balancing the body 101 while stabilizing the user.

[0057] In continuation, the rotary disc 111 with multiple compartments, each holding the single dose of medicine, placed inside the cylindrical container 112 provided on the body 101 with the dispensing chute at the bottom portion. The stepper motor rotates the disc 111 at scheduled times, aligning correct compartment with dispensing chute, releasing the correct dose through the spring-loaded flap 113 provided with the chute, and preventing accidental dispensing. The microcontroller adjusts the difficulty of cognitive games based on user’s cognitive level and age, with more complex tasks for user(s) in the early stages of dementia and simpler tasks with more visual and auditory cues for user(s) in advanced stages of dementia. Further the imaging unit 103 monitors user’s location and provides audible and visual alerts when the user approaches the restricted area, guiding them away from the unsafe zone and notifying caregivers of the user proximity to danger. Furthermore, the microcontroller collects and displays real-time insights about user’s health, cognitive state, and behavior, providing detailed reports to caregivers and family members, and generating alerts when unusual activities or medical issues, such as falls or irregular heart rate, are detected.
