[0002] Tranquility and health are the most important pillars, intertwined in the complex stages of human existence and in various environments. Particularly vulnerable groups, such as infants and toddlers, experience restlessness at night, frequent awakenings, and disrupted sleep. Their developmental vulnerability makes them acutely aware of external stimuli, changes in room temperature, and unsettling dreams.

[0003] Older adults are often confined to bed due to health-related problems and environmental factors, frequently struggling with sleep disorders. Whether within the sterile walls of a hospital or in the comfort of their homes, a wide variety of patients—from chronically hospitalized and outpatients to intensive care and those with mental disorders—are often bedridden. Spatial cognition, post-traumatic states, dementia, and confusion can sometimes prevent them from staying in bed, especially at night.

[0004] Therefore, there is an urgent need for innovative solutions that transcend the limitations of existing technologies. The current situation requires improvement, not only to address the multifaceted challenges posed by sleep disorders but also to lay the foundation for transformation at the intersection of electrical appliances and human health.

[0034] This invention is a revolutionary solution designed to transform the sleep experience and overall health of individuals across different age groups and developmental stages. At its core lies an advanced sensor module, including passive millimeter-wave sensors, active millimeter-wave sensors (utilizing on-chip radar technology), or similar sensor technologies. This 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 a multifunctional integrated speaker that stores pre-recorded audio content and provides a curated selection of soothing audio sequences, ranging from human voice information to calming music. Users can personalize the experience using an external recording application on their mobile devices, pre-recording comforting messages and defining triggers for their playback. The system utilizes robust communication links such as Wi-Fi, Bluetooth, and 5G to achieve seamless data transmission and efficient control between the external recording application and the sensor module (radar module).

[0035] In one embodiment of this invention, the system not only monitors sleep but also monitors the environment. The system combines an external temperature sensor to obtain real-time ambient room temperature data.

[0036] In another embodiment, the system of this invention has a power management unit that utilizes power from the ceiling fan (internal to the indoor appliance) as the main power source and seamlessly integrates a backup battery to ensure uninterrupted operation. The sensor module operates continuously through adaptive power management, entering a low-power sensing mode during idle periods to conserve energy. The sensors reactivate upon detecting motion or an occupancy trigger to perform critical functions, such as detecting individual targets, classifying them (e.g., adults, toddlers, infants), and analyzing physical states such as sleep depth, calmness, anxiety, and restlessness.

[0037] This invention further integrates a radar sensor for precise detection and classification. The radar sensor acquires a detailed "radar point cloud," composed of data points representing the surfaces of individuals within the room. These data points are converted into individual objects or "targets" corresponding to the individuals in the room. An advanced algorithm is employed for classification, enabling the system to categorize individuals by age group and analyze their physical condition. This detailed analysis provides valuable insights into the sleep quality and comfort of the occupants. Furthermore, the system incorporates communication and control mechanisms. Acquired and processed data is transmitted to the ceiling fan controller and integrated speaker; this communication forms the basis for the system's responsive intervention. Upon detecting signs of restlessness or agitation in the occupant, the system immediately activates the integrated speaker, playing a pre-selected calming audio sequence; simultaneously, the system adjusts the ceiling fan speed and airflow direction to enhance comfort. This coordinated response aims to guide the awakened individual (whether an adult, toddler, or infant) back to a state of calm and deep sleep.

[0038] Furthermore, this invention is forward-thinking, aiming to bring environmental intelligence to a wider audience through sharing sensor data and processed information with other third-party devices. This sharing enables additional service applications based on the radar module having an uninterrupted power supply for continuous operation.

[0039] The radar module and interface of this invention include integration with other similar indoor electronic devices, including lighting devices, light bulbs, mirrors, and air conditioning units.

[0040] The radar module and interface of this invention can also be installed in a standalone radar device with full functionality.

[0041] This invention delves into the field of electrical equipment and appliances, with a particular focus on utilizing these technologies to improve human health. This innovation pays special attention to the transformative potential of appliances such as ceiling fan components, which can not only monitor but also actively promote uninterrupted and restorative sleep.

[0042] The beneficial effects of this utility model are:

[0043] This invention combines cutting-edge sensor technology with carefully designed audio interventions to create an atmosphere conducive to peaceful sleep and relaxation.

[0052] The following is a detailed description of embodiments of the present invention as illustrated in the accompanying drawings. The detailed description of the embodiments is intended to clearly convey the present invention. However, the detailed description of the embodiments is not intended to limit the contemplative variations of the embodiments; rather, it is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention.

[0053] The following description sets forth numerous specific details in order to provide a thorough understanding of the embodiments of the present invention. It will be apparent to those skilled in the art that embodiments of the present invention may be practiced without some of these specific details.

[0054] This utility model discloses a sleep monitoring and intervention system (hereinafter referred to as "the system"), comprising: an indoor electrical appliance (such as a ceiling fan) integrating a radar sensor and other sensor modules for detecting the presence of an individual and sleep-related activities; a detector for detecting the level of restlessness of an awakened individual (e.g., a person in bed or an infant 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 based on the detected level of restlessness of the individual, and to adjust the speed of the ceiling fan to create an environment conducive to promoting comfort and encouraging the return to sleep; and a power management unit for supplying power to the ceiling fan and the control unit.

[0055] This system can be integrated into other similar indoor electronic devices, including fully functional lighting fixtures, light bulbs, mirrors, and air conditioning units. It can also be integrated into standalone radar devices with full functionality. Integrating radar sensors and other sensor modules (e.g., radar modules or on-chip radar) into any indoor electronic device provides similar functionality. This provides compatibility with existing electronic devices or appliances.

[0056] The core functions of this system include detecting, analyzing, and transmitting sleep-related data, including sleep state, posture, and levels of anxiety or restlessness. Key features and functions include radar sensor detection, data processing, classification algorithms, transmission of acquired data, activation of soothing audio sequences, and environmental adjustment via ceiling fans. The various components of the system work seamlessly together to improve sleep quality and overall health for individuals of different age groups and developmental stages.

[0057] Reference Figure 1 The preferred embodiment of the sleep monitoring and intervention system of this utility model includes an adaptive sleep indoor appliance, which takes an adaptive sleep ceiling fan as an example. The user sends instructions to the adaptive sleep ceiling fan.

[0058] 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 the 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 a communication link or network, such as wireless transmission between the user and the ceiling fan via a network. The radar sensor is used to determine the presence of an individual (e.g., a child) in the room or facility. Furthermore, the radar sensor is used to determine the sleep state of the individual (e.g., the child) in the room. The computing device 102 can be a mobile terminal, tablet, computer, laptop, or any other computing device.

[0059] Figures 2A-2E This describes the working principle of the sleep monitoring and intervention system according to a preferred embodiment of the present invention. The sensors integrated into the adaptive sleep ceiling fan detect and determine whether the individual is awake or in a non-sleep state, or detect sleep states such as confusion or distress. Based on the user's pre-programming, the speakers integrated into the adaptive sleep ceiling fan will play verbal instructions, songs, or lullabies to induce sleep.

[0060] Figure 3This 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 airborne antenna 340, and a power management unit 350; wherein the ceiling fan with the speaker and the power management unit 350 can communicate with each other. This system can achieve adaptive sleep functions, utilizing radar technology, artificial intelligence, and communication mechanisms to provide comprehensive and rapid-response functions in enhancing the sleep environment. For example, the AI ​​processor 320, the on-chip radar (ROC) 330, the communication link, the power management unit 350, and the airborne antenna 340 are all integrated in the radar module 310, which uses cutting-edge technology for accurate detection, classification, and data processing. The AI ​​processor performs complex data analysis, classifying detected individual targets by age group and analyzing their physical state through algorithms, providing real-time decision-making and valuable insights into the occupant's sleep status.

[0061] Figure 4 This is a flowchart of a preferred embodiment of the sleep monitoring and intervention method of the present invention, which is performed using an adaptive sleep ceiling fan. The method includes the following steps 410-470.

[0062] Step 410: Continuously monitor the individual in the bed, including infants, toddlers and adults, and use a sensor system to detect sleep states such as movement, restlessness and signs of arousal.

[0063] Step 420: If the system determines that the individual's sleep state is calm and shows no signs of restlessness or arousal, it proceeds to the delay period. The duration of this delay (D seconds) allows the system to confirm that the individual remains calm. The delay time (D seconds) allows the system to avoid unnecessary intervention if the individual returns to a calm state after brief activity.

[0064] Step 430: Trigger the track playback logic. If the system detects that the individual's sleep state is not calm, possibly experiencing restlessness or awakening, the track playback logic will be triggered. This logic is designed to select and play a pre-recorded calming audio sequence to soothe the individual. The track playback logic involves selecting from a series of soothing audio sequences, including verbal affirmations, calming music, or others.

[0065] 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, ensuring that the auditory intervention continues until the individual's sleep state returns to a calm state or they fall asleep again. The auditory intervention is tailored to individual needs and can be adjusted according to changes in the individual's sleep state.

[0066] Step 450: Trigger the fan speed adjustment logic. Simultaneously with audio intervention, the system assesses whether adjusting the ceiling fan speed and airflow direction can further improve comfort. If adjustment is deemed necessary, the fan speed adjustment logic is triggered to adjust the fan speed. This logic adjusts the fan speed based on individual needs and the system's analysis of the individual's sleep state to create a comfortable sleep environment, complementing the audio intervention.

[0067] Playlist 460: The playlist is a key element of the sleep monitoring and intervention system, a comprehensive catalog of pre-saved soothing audio content accessible to the system during track playback logic. This catalog includes a series of carefully designed audio sequences aimed at creating a calming and relaxing environment, including options such as verbal affirmations, calming music, guided meditation, and natural sounds. Playlists can also be stored in system memory via external sources (such as mobile applications), enabling rapid and customized audio interventions (or auditory interventions). Their importance lies in providing a personalized auditory experience, as the system intelligently selects sequences based on factors such as individual age, sleep state (e.g., severity of restlessness), and user-defined preferences. This dynamic and adaptive capability ensures the system can continuously relax the individual and promote sleep, contributing to health and uninterrupted rest.

[0068] In another embodiment, the method includes a temperature sensor input 470, which plays a crucial role in maintaining a comfortable and favorable sleep environment. The temperature sensor is strategically placed in the room, typically outside the sensor housing and near indoor electrical components such as ceiling fans, and its primary function is to continuously monitor the ambient room temperature. The sensor collects real-time temperature data, providing information about the current temperature conditions within the sleep area. This data is essential for assessing whether the room is too hot, too cold, or within the desired comfort range. The fan speed regulation logic uses the temperature sensor input as one of its triggering factors. If the sensor detects that the room temperature exceeds or falls below a predefined comfort threshold, it sends a signal to the fan speed regulation component. Upon receiving the temperature sensor input, the system's fan speed regulation logic begins to function, aiming to create an optimal and comfortable sleep environment by adjusting the speed of the ceiling fan. Based on the temperature sensor reading, the fan speed regulation logic may initiate one of the following responses:

[0069] Cooling response: If the room temperature is too high, the system increases the fan speed to enhance air circulation and produce a cooling effect; this is especially beneficial on hot nights, as individuals may have difficulty falling asleep due to the heat.

[0070] Heating Response: Conversely, if the room temperature is too cold, the system may reduce fan speed to decrease airflow. This helps prevent airflow and maintain a comfortable level of warmth, ensuring individuals remain comfortable on cold nights.

[0071] The fan speed control logic allows for gradual and seamless changes to the ceiling fan speed, preventing abrupt interruptions to the sleep environment and ensuring gentle, unobtrusive fan speed adjustments. The system allows users to define temperature comfort thresholds and fan speed preferences through a user-friendly interface, such as a mobile application. This personalization ensures the sleep environment matches individual comfort preferences.

[0072] In transmitting control signals and audio data, this invention incorporates continuous feedback for adaptive message delivery until a tranquil sleep is achieved. This dynamic function ensures continuous interaction between the system and the individual, allowing auditory interventions and control signals to be adjusted in real time according to changing sleep conditions. By providing adaptive information until a tranquil sleep state is reached, the system further enhances its ability to address different sleep patterns and disturbances, contributing to a more effective and personalized sleep experience.

[0073] Reference Figures 5A-5F In another scenario of the sleep monitoring and intervention system shown, and in another preferred embodiment of this invention, a nurse, teacher, or administrator sends instructions to the adaptive sleep ceiling fan of the sleep monitoring and intervention system. These instructions are delivered to the patient in the room via voice. In one embodiment, the system can be implemented in a hospital facility or children's dormitory. In another embodiment, the system can be implemented in any facility, where it can be used to determine an individual's sleep state, such as restlessness, and to induce sleep through the ceiling fan.

[0074] In this embodiment, the on-chip radar (ROC), as a key sensor module integrated into the radar module of an indoor appliance (ceiling fan), is capable of detecting and capturing radar echoes to generate a detailed "radar point cloud" representing the surface of individual objects 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, classifications, and body states via communication links such as Wi-Fi, Bluetooth, 5G, or similar protocols, ensuring efficient control and data sharing. The module effectively manages power consumption to ensure continuous operation during room activity detection and classification, and employs 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, facilitating efficient data transmission between the module and other system components such as the ceiling fan controller and speakers. This mechanism saves energy while maintaining reliable communication, which is crucial for accurate detection, classification, and response. Data transmission utilizes wireless communication protocols, including Wi-Fi, Bluetooth, 5G, or similar technologies, and power management control ensures optimized range and power efficiency. In scenarios without ceiling fan power 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 airborne antenna, strategically positioned to achieve optimal indoor coverage, which is crucial for capturing radar echoes and facilitating accurate detection and classification of individuals and their activities.

[0075] Communication between the ceiling fan controller and the power management unit is a key aspect of this sleep monitoring and intervention system. This interaction ensures efficient management of power resources, data exchange, and coordination of system functions. The ceiling fan controller receives data from an integrated sensor module that detects the presence of people in the room, sleep-related activities, and other relevant information. This data includes detailed information about the occupants, their physical condition, and intervention needs to promote tranquil sleep. Upon receiving this data, the ceiling fan controller interprets and analyzes it, making decisions by categorizing individuals according to age (adults, toddlers, infants, etc.) and assessing their physical condition, including sleep depth, calmness, restlessness, agitation, posture, and movement. To optimize the communication process and ensure efficient power use, the ceiling fan controller interacts with the power management unit, an interaction crucial for several reasons. The power management unit manages the allocation of power resources used for data transmission and reception, determining the appropriate power level required for reliable communication. When the system is in a low-power mode (e.g., when the room is unoccupied or individuals are inactive), the power management unit can prioritize energy conservation to extend the life of the backup battery. The power management unit (PMU) maintains the reliability of data exchange between the ceiling fan controller and other components, such as the radar module and integrated speaker, ensuring that interventions are based on accurate information. Based on the analysis of sensor data and individual classification, the ceiling fan controller may need to adjust the fan speed and direction in real time to optimize occupant comfort. These adjustments are coordinated with power management controls to ensure effective transmission of control signals.
