Description:FIELD OF THE INVENTION

[0001] The present invention relates to a sleep optimization system that is capable to continuously monitor the user’s body condition during rest in real time and detects any abnormal variations promptly, enabling early identification of physiological changes related to comfort, stress, or health issues while the user is sleeping or resting and provide assistance to the user for an enhanced sleeping experience.

BACKGROUND OF THE INVENTION

[0002] Many individuals struggle to maintain consistent sleep quality due to varied factors such as fluctuating body temperature, stress, discomfort, and irregular breathing patterns. Traditional bedding does not respond to sudden physiological changes or provide real-time adjustments to improve rest. Users often wake up due to overheating, sweating, or misalignment in posture, leading to sleep fragmentation and fatigue. Manual adjustments during sleep disrupt the natural sleep cycle and provide no personalized regulation based on changing bodily needs. Existing solutions like blankets or weighted sheets are static and do not adapt to the user’s changing condition through the night. Therefore, there is a need for a system that continuously monitors the user’s physiological state and dynamically optimizes comfort during sleep.

[0003] Several existing devices aim to improve sleep, such as heated blankets, cooling mattress pads, weighted blankets, and wearable sleep trackers. However, these products function independently and lack real-time integration of body data with active adjustment. Heated or cooling pads often provide only a constant temperature and do not adapt to changing body needs throughout the night. Weighted blankets provide pressure but do not adjust automatically if the user becomes restless or overheated. Wearable trackers monitor sleep but do not provide any physical comfort response. None of these devices offer a combined solution that senses physiology and dynamically activates heating, cooling, breathable, or pressure layers in a single integrated system.

[0004] WO2018023135A1 integrates sensors and other inputs to detect specific sleep environment conditions including point-specific pressure and/or temperature conditions. The bed includes a controller for commanding actuator or other devices to adjust these conditions. The controller may do so based on reference patterns for conditions and profiles of desired conditions. Information regarding the conditions may be provided to a remote computer, which may analyze the conditions and provide revised profiles of desired conditions.

[0005] EP2976994A3 discloses a sleep assist system to monitor and assist the user's sleep, comprises: a bedside device adapted to be positioned near the user's bed, the bedside device optionally comprising a loudspeaker, a light source, a microphone, a light sensor, a temperature sensor, a control unit, an air quality sensor, a display unit, a user interface. The system further comprises a first sensing unit positioned in the user's bed comprising one or more sensors adapted to sense at least pressure and changes in pressure exerted by the user lying in the bed. An additional sensor device is in contact with the user's body, and coupled to the bedside device. The system is configured to correlate the data obtained from both the first sensing unit and the additional sensor device.

[0006] Conventionally, many systems are available in the market for optimizing sleep of the user. However, the cited inventions lack to provide real-time adaptive comfort based on dynamic physiological feedback. The cited inventions either focus on monitoring without physical regulation, or provide temperature or pressure control without sensing multiple body parameters. Hence, current systems fail to deliver a unified and automated solution tailored to the user's changing sleep needs.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a system is required to be capable of continuously sensing multiple physiological parameters and accordingly adjusting cooling, heating, or pressure features in real time. Such a system should integrate monitoring and active response within a single platform, thereby enhancing comfort, reducing disturbances, and improving overall sleep quality.

DETAILED DESCRIPTION OF THE INVENTION

[0018] 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.

[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 sleep optimization system that continuously monitors the user’s body condition in real time during rest, ensuring accurate detection of physiological changes, and further to apply gentle pressure whenever restlessness or discomfort is detected, and provide thermal conditioning when required, allowing the system to improve overall rest quality through both monitoring and responsive pressure application.

[0022] Referring to Figure 1, an isometric view of a sleep optimization system is illustrated, comprising a flat, flexible structure 101, a hollow cylindrical body 102 arranged on a side of the structure 101 with a plurality of internal rollers 103, a pair of rotating disks 104 mechanically coupled with the rollers 103, a pair of horizontal sliding rails 105 mounted on either side of the structure 101, a detachable electronics module 106, a set of integrated pogo pin-based connections 107 and a set of electromagnetic locking blocks 108 are associated with the rails 105.

[0023] The system disclosed in the present invention includes a flat, flexible structure 101 adapted to be deployed over a user’s body during rest. The structure 101 is designed to conform to the body contours without restricting motion and serves as a foundation. The flexible structure 101 possesses textile-like softness to ensure user comfort throughout prolonged periods of use, particularly during sleep.

[0024] A user-interface inbuilt in a computing unit wirelessly linked with the system is accessed by a user to provide input personalized comfort preferences, such as preferred sleeping temperature zones or pressure settings, which are then processed by an inbuilt microcontroller to customize the sheet deployment pattern and operational parameters for improved comfort. 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 system and the computing unit is achieved through a communication module.

[0025] The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the system is preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11 protocols. It connects to a network via an access point, converting digital data into radio signals. The module processes TCP/IP protocols for data exchange, interfaces with the inbuilt microcontroller through UART/SPI, and ensures encrypted communication using WPA/WPA2 security standards for secure and efficient wireless connectivity.

[0026] An array of physiological sensors is embedded within the flexible structure 101 to continuously monitor critical parameters of the user's body. The sensors include at least one ECG sensor configured to monitor electrical activity of the user’s heart. The ECG sensor functions by detecting the electrical impulses generated during each heartbeat. The ECG sensor consists of conductive electrodes embedded in the fabric and placed in contact with the user’s skin. These electrodes capture small voltage changes that occur when the heart muscle depolarizes and repolarizes. The captured signals are amplified and filtered to remove noise and motion artifacts. The processed signals are then converted into digital data using an analog-to-digital converter and sent to the microcontroller linked with the system for real-time monitoring and analysis. By analyzing the waveform, the microcontroller interprets heart rate, and detect abnormalities such as arrhythmias or stress-induced changes.

[0027] At least one temperature sensor is embedded in the array of physiological sensors to detect body temperature at multiple regions. 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.

[0028] At least one respiratory sensor woven into the fabric to measure breathing rate and chest expansion. The respiratory sensor embedded in the fabric operates by detecting the expansion and contraction of the user’s chest or abdomen during breathing. The respiratory sensor preferably uses a stretchable conductive material or piezoelectric film integrated into the textile layer. As the user inhales and exhales, the fabric stretches and relaxes, causing a change in electrical resistance or voltage across the sensor. These variations are measured and converted into a respiratory signal, which is amplified, filtered, and digitized. The microcontroller analyzes the breathing pattern and rate in real-time, enabling detection of irregular breathing, apnea events, or stress-related rapid respiration during sleep.

[0029] At least one humidity sensor is embedded in the array of physiological sensors for detecting perspiration or skin moisture to evaluate hydration or stress. 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 microcontroller.

[0030] A plurality of pressure sensors and IMU (Inertial Measurement Unit) arranged beneath the fabric to detect the user's posture, movements, and restlessness during sleep. The pressure sensor used here is a capacitive pressure sensor that works by measuring changes in capacitance. The pressure consists of two conductive members separated by a small gap. When pressure is applied, the gap between the member is changed, altering the capacitance. The sensor detects this change and converts it into an electrical signal that relates to the amount of pressure. This signal is then sent to the microcontroller to be processed to give a precise pressure reading.

[0031] The IMU detects sleeping posture by continuously measuring the body’s orientation and movements using accelerometers, gyroscopes, and magnetometers. Accelerometers sense gravitational direction, determining whether the user lies on the back, side, or stomach. Gyroscopes track rotational shifts, helping identify posture changes during sleep. Magnetometers provide reference for absolute orientation, improving accuracy. The collected motion and orientation data are processed by the microcontroller that classify body positions and transitions. By analyzing prolonged stillness, angular orientation, and pressure distribution patterns, the IMU reliably detects and records sleeping postures, offering insights into sleep quality, restfulness, and potential health or ergonomic issues.

[0032] For example, when the user lies on the fabric-covered surface (bed/mattress), the body weight creates pressure that varies with posture. In the supine position, pressure spreads across shoulders, back, and hips. If the user is lying on the side, the body concentrates pressure on one shoulder, arm, and hip and while sitting or turning, pressure shifts quickly and unevenly, allowing the sensor to detect posture changes and movement patterns accurately.

[0033] The user lies on a fabric-covered surface, applying pressure to embedded pressure sensors. These sensors continuously monitor pressure, remaining stable during stillness and fluctuating with tossing or turning. The variations are converted into electrical signals, where stable waveforms indicate restful sleep and frequent fluctuations indicate restlessness. The microcontroller analyzes signal frequency, amplitude, and stability duration. Based on this, sleep is classified: minimal movement signals restful sleep, small frequent changes indicate mild restlessness, and large frequent shifts indicate high restlessness.

[0034] All sensors are interconnected using conductive threads woven within the structure 101, ensuring low-resistance electrical connectivity without compromising the softness and drape of the fabric. These conductive threads lead to a detachable electronics module 106, allowing washability of the fabric. The electronics module 106 uses pogo pin-based contacts 107 that realign automatically with the sensor pads for effortless reconnection and full restoration of sensor functionality after washing.

[0035] The electronics module 106 contains the microcontroller, signal conditioning circuits, an analog-to-digital converter and a power management circuit. The electronics module 106 interfaces with the conductive threads of the smart textile through spring-loaded pogo pins 107, which automatically align and press onto metallic sensor pads when the module is clipped in place. This ensures reliable electrical connectivity without soldering. Once connected, the module powers the sensors, collects their signals, processes the data, and transmits it to the microcontroller for monitoring and control.

[0036] A hollow cylindrical body 102 is mounted on the structure 101 and houses a plurality of internal rollers 103. Each roller supports a corresponding flexible sheet wound in a rolled configuration. These sheets are made of materials that provide thermal insulation, cooling, breathability, or gentle weight as required.

[0037] A pair of rotating disks 104 are mechanically coupled to the rollers 103 and configured to drive the rolling or unrolling of specific sheet layers. The rotating disk 104 rotate to selectively actuate the required roller, allowing controlled deployment of individual sheets to provide localized coverage, warmth, , or gentle pressure to specific zones of the user’s body.

[0038] The rotating disk 104 is equipped with a DC motor to provide rotation motion to the disk 104 for deploying the thermal insulation sheet. The DC motor converts electrical energy into mechanical energy using direct current. The DC motor operates based on the principle of electromagnetic induction. The motor consists of key components: a rotor (armature), a stator with permanent magnets or electromagnets, a commutator, and brushes. When current flows through the armature winding, a magnetic field is generated that interacts with the magnetic field of the stator. The interaction of the magnetic fields creates a torque that causes the rotor to rotate. The commutator, in conjunction with the brushes, reverses the current direction in the armature windings periodically, ensuring continuous rotation in a single direction.

[0039] A pair of horizontal sliding rails 105 are mounted along the lengthwise edges of the flexible structure 101. Once the required sheet is deployed, the microcontroller actuates the rails 105 to guide the sheets across the width of the user's body, directing coverage to particular regions such as the upper torso, lower limbs, or midsection, based on real-time physiological needs.

[0040] An electromagnetic locking block 108 is associated with each of the rail 105 to lock the sheet over the sliding rail 105 once deployed. The electromagnetic locking block 108 consist of electromagnets attached on the rail 105 and the sheet. The electromagnet is made of insulated copper wire wound into a coil and a ferromagnetic material is placed inside the coil to enhance the magnetic field. When an electric current flows through the coil of wire, it creates a magnetic field around the wire. The magnetic field is concentrated and intensified by the core material inside the coil and strengthens the overall magnetic field produced by the coil. The created magnetic field attracts both the electromagnet connected to the sheet and sliding rail 105 toward each other creating a connection. When the current is turned off, the magnetic field collapses, and the electromagnet no longer attracts each other and sheet is released.

[0041] The sliding rail 105 consist of a motorized slidable member connected to the sliding rail 105. The motorized slidable member is attached to the electromagnetic block 108 and sliding rail 105 on both sides to make the electromagnetic block 108 slide. The slidable member is attached to a motor which provides movement to the member in a bi-directional manner to precisely position the sheet over the user.

[0042] The microcontroller serves as the primary control unit receiving data from the physiological sensors and issuing commands to the disks 104, rollers 103, and sliding rail 105 actuators. Based on body temperature, perspiration, heart rate, and respiratory variation, the microcontroller dynamically regulates the deployment, retraction, or positioning of sheets to achieve optimal thermal comfort or pressure-based soothing.

[0043] For instance, if overheating is detected by temperature sensors located near the lower body, the microcontroller selectively deploys breathable or cooling sheets over the lower limbs while maintaining insulation on the torso. In cases of detected restlessness or discomfort, the microcontroller deploys a weighted sheet layer to apply gentle pressure, promoting calmness and deeper sleep via deep-pressure stimulation.

[0044] The microcontroller is operatively connected with an IoT-enabled control module and communicates with an external home automation unit, such as air conditioning units and lighting modules. Based on signals from an ambient temperature sensor and a light sensor integrated within or near the system, the microcontroller adjusts ambient room temperature and lighting conditions to maintain an optimal sleep environment.

[0045] In case, the physiological sensors detect physiological patterns that suggest sleep disorders, signs of illness, heightened stress, or abnormal heart activity, the microcontroller analyzes this data and generates alerts. These alerts are then sent to the user or caregiver through the connected computing unit, enabling timely attention, monitoring, or medical intervention based on the identified health concerns.

[0046] Moreover, a battery is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes known as a cathode and an anode. A voltage is generated between the anode and cathode via oxidation/reduction and thus produces the electrical energy to provide to the device.

[0047] The present invention works best in the following manner, where the flat, flexible structure 101 is positioned over the user's body during rest while the array of physiological sensors continuously monitors metrics such as ECG, body temperature, respiration, humidity, and pressure to detect posture and movement. Real-time data from these sensors is transmitted via conductive threads to the detachable electronics module 106, where the microcontroller analyzes the signals and determines the required thermal or pressure-based response. Based on the analysis, the microcontroller actuates the rotating disks 104 to roll or unroll specific flexible sheets from the rollers 103 housed within the hollow cylindrical body 102, selectively deploying cooling, or weighted sheets to particular body zones. The sliding rails 105 guide the lateral movement of the sheets, while electromagnetic locking blocks 108 secure them in position once deployed. If overheating is detected, the microcontroller deploys cooling sheets over the body while maintaining insulation elsewhere, and if restlessness is detected, it deploys the weighted sheet to promote deep sleep. Alerts for abnormal physiological patterns are generated through the computing unit, and user preferences from the user interface are also considered to personalize comfort. Additionally, the system’s IoT-enabled control module communicates with external air conditioning and lighting units using ambient temperature sensor and light sensor inputs, thereby adjusting the environment to maintain optimal sleep conditions.
