[0002] Tranquility and well-being are the most important pillars, interwoven across all life stages and environments of complex human existence. Particularly vulnerable populations, such as infants and young children, experience restlessness at night, frequent awakenings and sleep disruptions. Their developmental vulnerabilities make them acutely aware of external stimuli, room temperature changes, and disturbing dreams.

[0003] Bedbound older adults may be due to health-related issues and environmental factors, often struggling with sleep disturbances. Whether within the sterile walls of a hospital or in the comfort of their own homes, a wide variety of patients—from chronic inpatients and outpatients to intensive care patients and those with psychiatric disorders—are often confined to their beds. Spatial cognition, post-traumatic states, dementia, and confusion sometimes prevent bedriddenness, especially at night.

[0004] Therefore, there is an urgent need for innovative solutions that go beyond the limitations of existing technologies. The current situation needs to be improved to not only solve the multifaceted challenges posed by sleep disorders, but also to lay the foundation for a transformation at the intersection of appliances and human health.

[0026] The present invention is a revolutionary solution that aims to transform the sleep experience and overall health of individuals of different age groups and developmental stages. The core of the system combines advanced sensor modules, including passive mmWave sensors, active mmWave sensors (utilizing on-chip radar technology), or similar sensor technologies. The sensor module is equipped with processing and communication capabilities to capture and interpret various aspects of an individual's presence, sleep patterns, and signs of arousal or restlessness. Complementing this sensor technology is an integrated speaker with multi-functions that stores pre-recorded audio content and provides a curated sequence of soothing audio, from human voice messages to calming music. Users can personalize the experience using an external recording application of a mobile device, pre-record comfort messages and define the situations that trigger their playback. The system of the present invention utilizes powerful communication links such as Wi-Fi, Bluetooth, 5G and other technologies to achieve seamless data transmission and efficient control between the external recording application and the sensor module (radar module).

[0027] In one embodiment of the present invention, the function of the system of the present invention is not only sleep monitoring, but also environment monitoring, and the system is combined with an external temperature sensor to obtain real-time ambient room temperature data.

The sensor reactivates upon detecting motion or occupancy triggers and performs key functions such as detecting individual targets, classifying them (e.g., adult, toddler, infant), and analyzing physical states such as sleep depth, calmness, agitation, and restlessness.

[0029] The present invention further incorporates radar sensors to enable precise detection and classification. The radar sensor acquires a detailed "radar point cloud" consisting of data points representing individual surfaces in the room. These data points are converted into individual objects or "targets" corresponding to individuals in the room. Advanced algorithms are used as classification algorithms, allowing the system to classify individuals according to age groups and analyze their physical state. This detailed analysis provides valuable insights into the sleep quality and comfort of the occupants. In addition, the system of the present invention has communication and control mechanism functions. The acquired data and processed data are transmitted to the controller and integrated speakers of the ceiling fan, and this communication forms the basis for the system's responsive intervention. Detecting signs of restlessness or agitation in the occupant, the system immediately activates, activating the integrated speakers and playing a pre-selected calming audio sequence; at the same time, the system adjusts the speed and airflow direction of the ceiling fan to improve comfort. This coordinated response is intended to guide the awakened individual (whether an adult, a toddler or an infant) back to a state of calm and deep sleep.

[0030] Furthermore, the present invention is forward-looking and intends to bring ambient intelligence to a wider audience by sharing sensor data and processed information with other third-party devices. This sharing opens up the possibility for additional service applications based on the radar module having an uninterruptible power supply to operate continuously.

[0033] This invention delves into the field of electrical devices and appliances, with a particular focus on using these technologies to improve human health. This innovation specifically focuses on the transformative potential of appliances, such as ceiling fan assemblies, to not only monitor, but actively promote uninterrupted and restorative sleep.

[0034] The beneficial effects of the present invention are: The system of the present invention combines cutting-edge sensor technology with carefully curated audio interventions to create an atmosphere conducive to restful sleep and relaxation.

[0043] The following is a detailed description of an embodiment of the present invention described in the accompanying drawings. The detailed description of the embodiment is to clearly convey the present invention. However, the detailed description of the embodiment is not intended to limit the expected changes of the embodiment, but is intended to cover all modifications, equivalents and alternatives that fall within the spirit and scope of the present invention.

[0044] The following description sets forth numerous specific details to provide a thorough understanding of the embodiments of the present invention. It is apparent to one skilled in the art that the embodiments of the present invention can be implemented without some of these specific details.

[0045] The present invention discloses a sleep monitoring and intervention system (hereinafter referred to as "the system"), comprising: an indoor appliance (such as a ceiling fan) integrated with a radar sensor and other sensor modules for detecting individual presence and sleep-related activities; a detector for detecting the restlessness of an awakened individual (such as a person in a bed or a baby in a crib); an integrated speaker for playing a pre-recorded audio sequence; a control unit programmed to generate responsive audio information, soothing sounds and music, and adjust the speed of the ceiling fan based on the detected restlessness of the individual to create an environment conducive to promoting comfort and encouraging restorative sleep; and a power management unit for powering the ceiling fan and the control unit.

[0046] The system can be integrated into other similar indoor electronic devices, including fully functional lighting fixtures, light bulbs, mirrors, and air conditioning units. The system can also be integrated into a fully functional standalone radar device. Any indoor electronic device that integrates radar sensors and other sensor modules (such as radar modules or radar-on-chip) can provide similar functions. This provides compatibility with existing electronic devices or appliances.

[0047] The core functions of the system include detection, analysis and transmission of sleep-related data, including sleep state, posture, and level of restlessness or agitation. Notable features and functions of the system include radar sensor detection, data processing, classification algorithms, transmission of acquired data, activation of soothing audio sequences, and environmental adjustments through ceiling fans. The various components of the system work seamlessly together to improve sleep quality and overall health of individuals of different age groups and developmental stages.

[0048] Reference Figure 1The sleep monitoring and intervention system of the preferred embodiment of the present invention includes an adaptive sleep indoor appliance. The adaptive sleep indoor appliance takes an adaptive sleep ceiling fan as an example. The user sends instructions to the adaptive sleep ceiling fan.

[0049] The adaptive sleep ceiling fan 100 includes a radar sensor connected to a network 104. A user 101 uses a computing device 102 to send a voice command 106 to a speaker of the ceiling fan 100. The command 106 can be a voice message, song, or lullaby sent to an individual (e.g., a child) 110. 107 and 108 represent communication links or networks, such as wireless transmissions between the user and the ceiling fan over a network. The radar sensor is used to determine the presence of an individual (e.g., a child) in a room or facility. In addition, the radar sensor is used to determine the sleep state of an individual (e.g., a child) in the room. The computing device 102 can be a mobile terminal, a tablet computer, a computer, a laptop, or any other computing device.

[0050] Figure 2A-2E This is the working principle of the sleep monitoring and intervention system of the preferred embodiment of the present invention. The sensor integrated with the adaptive sleep ceiling fan detects and determines that the individual is awake or in a non-sleeping state, or finds that the individual is in a sleep state such as confusion and distress. According to the user's pre-programming, the speaker integrated with the adaptive sleep ceiling fan will play verbal instructions, songs or lullabies to induce sleep.

[0051] Figure 3 3 is a block diagram of a sleep monitoring and intervention system according to a preferred embodiment of the present invention. An indoor appliance (such as a ceiling fan) 300 with an integrated speaker includes a radar module 310, an on-chip radar chip 330, an AI processor 320, an onboard antenna 340, and a power management unit 350; wherein the ceiling fan with a speaker and the power management unit 350 can communicate with each other. The system can implement an adaptive sleep function, using radar technology, artificial intelligence, and communication mechanisms to provide comprehensive and responsive functions in enhancing the sleep environment. For example, the AI ​​processor 320, the radar on chip (ROC) 330, the communication link, the power management unit 350, the onboard antenna 340, etc. are all integrated in the radar module 310, which uses cutting-edge technology for precise detection, classification, and data processing. The (artificial intelligence) AI processor performs complex data analysis, classifies the detected individual targets by age group and analyzes the physical state through algorithms, providing real-time decisions and valuable insights into the sleep status of the occupants.

[0052] Figure 4 4 is a flow chart of a sleep monitoring and intervention method according to a preferred embodiment of the present invention, which is performed using an adaptive sleep ceiling fan. The method includes the following steps 410 to 470.

[0053] Step 410: Continuously monitor an individual in bed, including infants, toddlers, and adults, with a sensor system detecting sleep states such as movement, restlessness, and signs of arousal.

[0054] Step 420: If the system determines that the individual's sleep state is restless and does not show signs of restlessness or arousal, a delay period is entered. The duration of this delay (D seconds) allows the system to confirm that the individual remains in a restless state. The delay time (D seconds) allows the system to avoid unnecessary intervention if the individual briefly moves and then returns to a restful state.

[0055] Step 430: Triggering the play track logic, if the system detects that the individual's sleep state is not restful and may be experiencing restlessness or arousal, the play track logic is triggered. This logic is designed to select and play a pre-recorded calming audio sequence to soothe the individual. The play track logic involves selecting from a series of soothing audio sequences, which can include verbal affirmations, calming music, or other.

[0056] Step 440: Trigger the playback duration logic, which determines the duration of the soothing audio sequence playback. The playback duration varies based on the system's assessment of the individual's sleep state, such as the level of restlessness or anxiety, to ensure that the auditory intervention continues until the individual's sleep state returns to a calm state or falls asleep again. The auditory intervention is tailored to the individual's needs and can be adjusted based on changes in the individual's sleep state.

[0057] Step 450: triggering the fan speed adjustment logic. While the audio intervention is in progress, the system evaluates whether adjusting the ceiling fan speed and airflow direction can further improve comfort. If the evaluation shows that adjustment is required, the fan speed adjustment logic is triggered to adjust the fan speed. The fan speed adjustment logic adjusts the fan speed to create a comfortable sleeping environment based on the individual's needs and the system's analysis of their sleep state, and assists the audio intervention.

[0058] Playlists 460: A key element in the sleep monitoring and intervention system, playlists are a comprehensive catalog of pre-saved soothing audio content that the system can access during the playlist logic. This catalog includes a series of carefully designed audio sequences designed to create a calm and relaxing environment, including options such as verbal affirmations, calming music, guided meditations, and nature sounds. Playlists can also be stored in the system memory via external sources (such as mobile terminal applications), allowing for quick and customized audio interventions (or auditory interventions), which are important in providing a personalized auditory experience because the system intelligently selects sequences based on factors such as the individual's age, sleep state such as the severity of restlessness, and user-defined preferences. This dynamic and adaptive functionality ensures that the system can continuously relax and promote sleep for individuals, helping to promote healthy and uninterrupted rest.

[0059] In another embodiment, the method includes a temperature sensor input 470, which plays a vital role in maintaining a comfortable and conducive sleeping environment. Temperature sensors are strategically placed in the room, typically located outside the sensor housing and near indoor electrical (such as ceiling fan) components, and their primary function is to continuously monitor the ambient temperature of the room. The sensor collects real-time temperature data, providing information about the current temperature conditions within the sleeping area. This data is critical in assessing whether the room is too hot, too cold, or within the desired comfort range. The fan speed adjustment logic uses the temperature sensor input as one of its triggers. If the sensor detects that the room temperature exceeds or falls below a predefined comfort threshold, a signal is sent to the fan speed adjustment component. Upon receiving the temperature sensor input, the system's fan speed adjustment logic begins to function with the goal of creating an optimal and comfortable sleeping environment by adjusting the speed of the ceiling fan. Based on the temperature sensor reading, the fan speed adjustment logic may initiate one of the following responses: Cooling response: If the room temperature is too high, the system increases the fan speed to increase air circulation and produce a cooling effect; this is especially beneficial on hot nights when individuals may have difficulty falling asleep due to the heat; Heating Response: Conversely, if the room temperature is too cold, the system may reduce fan speed to reduce air movement. This helps prevent draft activity and maintain a comfortable warmth level, ensuring individuals stay comfortable on cold nights.

[0060] The fan speed adjustment logic provides gradual and seamless changes to the ceiling fan speed, which prevents sudden interruptions to the sleeping environment and ensures that fan speed adjustments are gentle and unnoticeable. The system allows users to define temperature comfort thresholds and fan speed preferences through a user-friendly interface, such as a mobile app. This personalization ensures that the sleeping environment meets individual comfort preferences.

[0061] The present invention incorporates continuous feedback for adaptive messaging during the delivery of control signals and audio data until restful sleep is achieved. This dynamic functionality ensures a continuous interaction between the system and the individual, allowing for real-time adjustment of auditory interventions and control signals based on changing sleep conditions. By providing adaptive information until a restful sleep state is achieved, the system further enhances its ability to account for different sleep patterns and disturbances, helping to provide a more effective and personalized sleep experience.

[0062] Reference Figures 5A-5FAnother scenario of the sleep monitoring and intervention system shown in the figure, in another preferred embodiment of the present invention, a nurse or teacher or administrator sends an instruction to the adaptive sleep ceiling fan of the sleep monitoring and intervention system. The instruction sends instructions to the patient in the room by voice. In one embodiment, the system can be implemented in a hospital facility or a children's dormitory. In another embodiment, the system can be implemented in any facility, where the system can be used to determine the sleep state of an individual, such as a restless state, and induce the individual to fall asleep through a ceiling fan.

[0063] In this embodiment, the radar on chip (ROC) is a key sensor module integrated into the radar module of the indoor appliance (ceiling fan), which can detect and capture radar echoes to generate a detailed "radar point cloud" representing the individual surfaces in the room. Through precise measurements, including position (x, y, z) and radial velocity, ROC technology can accurately track individuals and their movements. The radar module communicates seamlessly with the ceiling fan controller, conveying information about detected individual targets, classification, and physical status through communication links such as Wi-Fi, Bluetooth, 5G or similar protocols to ensure efficient control and data sharing. The module can effectively manage power consumption so that it can operate continuously during detection of room activities and classification, and uses power control mechanisms to ensure reliability, even in low-power sensing modes. Power management control focuses on optimizing the power consumption of the radar module's communication functions and facilitating efficient data transmission between the module and other system components such as ceiling fan controllers and speakers. This mechanism saves energy while maintaining reliable communication, which is critical for accurate detection, classification, and response operations. Wireless communication protocols (including Wi-Fi, Bluetooth, 5G or similar technologies) are used for data transmission, and power management control is used to ensure optimized range and power efficiency. In scenarios where there is no power to the ceiling fan or in low-power sensing mode when the room is unoccupied, this mechanism prioritizes energy conservation to extend backup battery life. The radar module integrates an onboard antenna that is strategically positioned for optimal indoor coverage, which is critical to capturing radar echoes and facilitating accurate detection and classification of individuals and their activities.

[0064] Communication between the ceiling fan controller and the power management unit is a key aspect of the sleep monitoring and intervention system of the present invention. This interaction ensures efficient management of power resources, data exchange, and coordination of system functions. The ceiling fan controller receives data from the integrated sensor module, which is used to detect human presence in the room, sleep-related activities, and other relevant information. This data includes detailed information about the occupants, their physical state, and the need for intervention to promote restful sleep. After receiving this data, the ceiling fan controller interprets and analyzes it and makes decisions, classifying individuals according to age (adults, toddlers, infants, etc.) and assessing their physical state, including sleep depth, calmness, restlessness, restlessness, posture, and movement. In order to optimize the communication process and ensure efficient power usage, the ceiling fan controller interacts with the power management unit, which is critical for a number of reasons. The power management unit manages the allocation of power resources for data transmission and reception, determining the appropriate power level required for reliable communication. When the system is in a low-power mode (for example, when the room is unoccupied or during periods of individual inactivity), the power management unit can prioritize energy conservation to extend the life of the backup battery. The role of the power management unit is to maintain the reliability of the data exchanged between the ceiling fan controller and other components (such as the radar module and integrated speakers), which ensures that interventions are based on accurate information. Based on the analysis of the sensor data and the classification of the individual, the ceiling fan controller may need to adjust the speed and direction of the ceiling fan in real time to optimize the comfort of the occupants. These adjustments are coordinated with the power management control to ensure that the control signals are transmitted effectively.
