CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Patent Application Ser. No. 63 / 641,478, filed May 2, 2024, which is herein incorporated by reference in its entirety.BACKGROUND
[0002] The human body is a heat generator and a thermally sensitive system. A large fraction of the energy input to human body as food (chemical energy) is converted to thermal energy (heat) and must be dissipated to the environment to maintain a healthy core temperature. In normal conditions, a human body's thermoregulatory system enables the heat dissipation to the environment and regulation of the core body temperature.
[0003] The thermoregulatory system's capacity to dissipate heat to the environment is dependent on ambient temperature, humidity, sunlight intensity, elevation, cardiovascular system's health, age, and several other parameters. In hot and hot-humid conditions the thermoregulatory system's capacity to dissipate heat to the environment quickly deteriorates. Over time, reduced heat dissipation to the environment (or reverse heat flow in extreme heat wave cases) may lead to thermal energy (heat) accumulation in human body and increase in core temperature above the healthy level. Elevated core temperatures lasting over an extended period (heat stress) may lead to heat stroke, permanent damage to vital organs (kidney, brain, heart, and liver), and eventually death.SUMMARY

In certain disclosed embodiments, the adaptive personalized thermal management system monitors several parameters including ambient conditions, user's biomarkers, metabolic activity level, and motion in order provide the required heat exchange capacity (needed cooling / heating power) and to maintain a comfortable and healthy thermal condition. Unlike existing technologies, the disclosed adaptive personalized thermal management system adjusts its thermal response (heating or cooling) constantly based on the data provided by its sensors, available external data, and user's own thermal profile.

[0029] The user computing device 102 can also include one or more user input components 122 that receives user input. For example, the user input component 122 can be a touch-sensitive component (e.g., a touch-sensitive display screen or a touch pad) that is sensitive to the touch of a user input object (e.g., a finger or a stylus). The touch-sensitive component can serve to implement a virtual keyboard. Other example user input components include a microphone, a traditional keyboard, or other means by which a user can provide user input.
[0030] The server computing system 130 includes one or more processors 132 and a memory 134. The one or more processors 132 can be any suitable processing device (e.g., a processor core, a microprocessor, an ASIC, an FPGA, a controller, a microcontroller, etc.) and can be one processor or a plurality of processors that are operatively connected. The memory 134 can include one or more non-transitory computer-readable storage media, such as RAM, ROM, EEPROM, EPROM, flash memory devices, magnetic disks, etc., and combinations thereof. The memory 134 can store data 136 and instructions 138 which are executed by the processor 132 to cause the server computing system 130 to perform operations.
[0031] In some implementations, the server computing system 130 includes or is otherwise implemented by one or more server computing devices. In instances in which the server computing system 130 includes plural server computing devices, such server computing devices can operate according to sequential computing architectures, parallel computing architectures, or some combination thereof.
[0032] As described above, the server computing system 130 can store or otherwise include one or more machine learning models 140. For example, the models 140 can be or can otherwise include various machine-learned models. Example machine-learned models include neural networks or other multi-layer non-linear models.

Some example machine-learned models can leverage an attention mechanism such as self-attention. For example, some example machine-learned models can include multi-headed self-attention models (e.g., transformer models).
[0033] The user computing device 102 and / or the server computing system 130 can train the models 120 and / or 140 via interaction with the training computing system 150 that is communicatively coupled over the network 180. The training computing system 150 can be separate from the server computing system 130 or can be a portion of the server computing system 130.
[0034] The training computing system 150 includes one or more processors 152 and a memory 154. The one or more processors 152 can be any suitable processing device (e.g., a processor core, a microprocessor, an ASIC, an FPGA, a controller, a microcontroller, etc.) and can be one processor or a plurality of processors that are operatively connected.

[0035] The training computing system 150 can include a model trainer 160 that trains the machine-learned models 120 and / or 140 stored at the user computing device 102 and / or the server computing system 130 using various training or learning techniques, such as, for example, backwards propagation of errors. For example, a loss function can be backpropagated through the model(s) to update one or more parameters of the model(s) (e.g., based on a gradient of the loss function). Various loss functions can be used such as mean squared error, likelihood loss, cross entropy loss, hinge loss, and / or various other loss functions. Gradient descent techniques can be used to iteratively update the parameters over a number of training iterations.
[0036] In some implementations, performing backwards propagation of errors can include performing truncated backpropagation through time.

[0038] In some implementations, if the user has provided consent, the training examples can be provided by the user computing device 102. Thus, in such implementations, the model 120 provided to the user computing device 102 can be trained by the training computing system 150 on user-specific data received from the user computing device 102. In some instances, this process can be referred to as personalizing the model.
[0039] The model trainer 160 includes computer logic utilized to provide desired functionality.

In general, communication over the network 180 can be carried via any type of wired and / or wireless connection, using a wide variety of communication protocols (e.g., TCP / IP, HTTP, SMTP, FTP), encodings or formats (e.g., HTML, XML), and / or protection schemes (e.g., VPN, secure HTTP, SSL).
[0041] FIG. 1B depicts a set of exemplary modes operating on a computing device 190. As depicted, cooling mode 191, heating mode 192, or other user customized modes 193 may receive various inputs in the operation of these modes. For example, sensors 194 may provide sensor data, context manager 195 may provide context data, device state variables 196 may provide device state data, and other additional components 197 may provide additional data (e.g., statistical data).

[0044] FIG. 2 illustrates a high-level block diagram of one embodiment adaptive personalized thermal management system 200. User 210 is equipped with wearable thermal interface unit 220 which provides heating and cooling to user 210. In the disclosed embodiment, User 210 is also able to interact with user interface unit 230. However, in certain embodiments user interface unit 230 may not be present, or may be an extremely simplified interface. Throughout FIG. 2, thermal exchange occurs at exchanges 205.
[0045] User interface unit 230 is configured to interact with and inform power and control unit 240. Power and control unit 240 is operatively connected to heat exchange components: wearable thermal interface unit (WITU) 220, active thermal unit (ATU) 250, and heat exchange unit (HEU) 260. Power and control unit provides and adjusts power to each of these units. In certain embodiments, sensors and electronics are housed in a water-resistant, durable casing. The power and control unit and associated sensors and electronics may be of a compact, lightweight design for seamless integration into the wearable thermal interface unit.
[0046] Wearable thermal interface unit (WITU) 220 interfaces with user 210 and may be in the form of a vest, hat, helmet, neck collar, shirt, pants, shorts, or other wearable item, such as a backpack or a portion of a backpack. Further, wearable thermal interface unit 220 may be a combination of these wearable items, e.g., a vest and a hat, vest hat and collar, etc. The wearable item(s) of wearable thermal interface unit 220 includes a fluid circulation system with tubing, contact surfaces, and materials that facilitate heat transfer from the skin surface to the circulating fluid, or vice-versa.
[0047] Active thermal unit (ATU) 250 is itself operatively connected to wearable thermal interface unit 220 and may exchange heating and cooling with wearable thermal interface 220. Active thermal unit 250 adjusts the temperature of the working fluid which flows into the wearable thermal interface unit 220. Active thermal unit 250 may employ a single or a combination of cooling-heating mechanisms to change the temperature of the working fluid circulating through the wearable thermal interface unit and active-thermal unit. For example, in certain embodiments, ATU 250 may utilize thermoelectric modules (TECs) coupled with an air heat exchanger. In another embodiment, ATU 250 may utilizes TECs coupled with a liquid heat-exchanger. In another embodiment, ATU 250 may utilize TECs coupled with a phase-change-heat-exchanger, such as solid-liquid, liquid-vapor, solid-vapor, or a combination of all three. In other embodiments, a combination of TECs coupled with different heat-exchangers may be utilized, e.g., both an air and liquid heat-exchanger, an air and phase-change heat-exchanger, a liquid and phase-change heat exchanger, or a combination of all three. In each instance, TEC operation may be optimized based on the teachings contained in this disclosure.
[0048] Furthermore, active thermal unit 250 may exchange heating and cooling with heat exchange unit 260. Heat exchange unit 260 is configure to interface and provide exchange of hot / cold with the outside environment (or relevant ambient environment). When adaptive personalized thermal management system 200 is operating in a cooling mode, heat exchange unit 260 operates as a heat dissipation mechanism, absorbing the total energy from user 210 and waste heat generated by ATU 250.
[0049] User interface unit 230 allows control of adaptive personalized thermal management system. In certain embodiments, the user interface associated with the user interface unit is provided using an app on a user's phone, smart watch, or other similar device. In other embodiments, the user interface may be provided by attachment to the wearable systems, with either a wired or wireless connection to power and control unit. In other embodiments, a combination of an app-based interface and a directly connected interface may be used. User interface unit 230 allows the user to control various settings and functions of adaptive personalized thermal management system, including, for example, setting the desired temperature, choosing from existing present programs, or activating a personalized adaptive mode, which may incorporated various AI-based methods or may otherwise use adaptive logic based on the input of various items of the input array.
[0050] In operation, the adaptive personalized thermal management system is configured to operate utilizing an array of input data which informs power and control unit 240. Input data may include both user-specific data and environment specific data. For example, user-specific data may include, but is not limited to, a user's temperature, motion, heart rate, bloody oxygen level, breathing rate, and metabolic activity level. Environment-specific data may include, but is not limited to temperature, humidity, sunlight intensity, elevation, and windspeed. These data may be considered as point-in-time measurements, historical data, or use predictive information, for example.
[0051] Adaptive personalized thermal management system 200 via power and control unit 240 may be operated in a manual mode through user input via the user interface. System 200 may also be operated using adaptive operation which leverages an integrated AI system such as the one disclosed in connection with FIGS. 1A and 1B. In other modes of operation, adaptive personalized thermal management system may utilize previously programmed operations. For example, a user undergoing medical treatments where cooling or heating may be valuable for the health or comfort of a patient, a programmed response may be utilized. Similarly, if certain emergency response situations (e.g., heat stroke, overheating, or known intense thermal environments) are encountered, a programmed treatment may be utilized. Additionally, a combination of any of the above modes may be utilized.
[0052] An operating mode for adaptive personalized thermal management system may be considered a Thermal Operating Mode comprising a cooling mode and a heating mode. In a cooling mode, circulating fluid is cooled to the desired temperature by Active Thermal Unit 250. The cooled fluid will then enter a fluid distribution system embedded in the structure of the wearable item (e.g., vest, hat, neck collar, etc.) and is brought into thermal contact with the user's skin (either directly or indirectly across clothing) where it provides the required cooling power to maintain user's temperature at a healthy level. As a result of heat exchange with the user's body the fluid temperature increases. The warm fluid then flows back to the wearable system heat-exchange unit to be cooled again and repeat the cycle again.
[0053] In a heating mode, an operation similar to the cooling mode occurs, but essentially in reverse. Circulating fluid is warmed up in Active Thermal Unit 250 to a temperature higher than the user's body temperature. The circulating fluid then enters the wearable fluid distributing system and warms the skin. The cooled fluid then flows back to Active Thermal Unit 250 to repeat the cycle.
[0054] Certain non-limiting examples of possible use cases for the wearable the following examples are given in more detail below.Workplace Applications
[0055] In one example, the personalized adaptive thermal management system may be deployed in workplace environments. For example, the personalized adaptive thermal management system may protect workers exposed to heat from heat stress and prevents decline in workplace productivity. Through its use, the system helps workers to stay thermally comfortable and prevents dehydration. Due to its continuous monitoring of user vital data, the personalized adaptive thermal management system can alert the user to stop working when heat stress / stroke is imminent.Medical Applications
[0056] Multiple different medical applications may employ the personalized adaptive thermal management system, including in diagnostic, safety and prevention, and emergency response settings. Furthermore, the personalized adaptive thermal management system may be used in connection with other medical treatments which may cause heating or cooling sensation to the user, e.g., chemotherapy treatments. Some exemplary aspects of the diagnostic, safety and prevention, and emergency response uses are detailed below:Diagnosis
[0057] The ability of the human body to regulate its temperature and withstand extreme heat or cold is often closely linked to the health of its cardiovascular and other essential systems. By utilizing the array of inputs available to the personalized adaptive thermal management system the system may build a dynamic personal thermal profile for each user over time. An artificial intelligence system may utilize the thermal profile in addition to monitored parameters to provide the thermal response. The thermal profile for each user and his / her health data monitored by multiple sensors can be utilized for a wide range of medical diagnosis purposes.Safety and Prevention
[0058] The personalized adaptive thermal management system safeguards against dehydration, thermal stress, heat stroke, and heat-related illnesses by ensuring the human body remains within a healthy thermal state. The system may alleviate strain on the thermoregulatory system and provide particular benefits to the cardiovascular system and heart through maintaining this desired thermal state.Response to Heat-Related Emergencies
[0059] The personalized adaptive thermal management system provides a safer and more efficient alternative to existing treatments. In contrast to existing procedures and treatments the system provides a controlled and safe treatment by precise control of the cooling power and intensity, thus preventing the human body from exposure to extremely cold temperatures. The personalized adaptive thermal management system may be used in situations of both extreme heat and extreme cold, useful in preventing both heat stroke and hypothermia.
[0060] FIG. 3 depicts an embodiment of the personalized adaptive thermal management system utilizing an air-cooled heat exchanger. Turning first to heating portions of the system, thermoelectric module (TE) warm side contact plate 310 is associated with TE warm side 330. The thermoelectric module relies on the Peltier effect, where an electric current causes a temperature difference, allowing for heat flow in the desired direction and for precise temperature control. TE warm side contact plate 310 is in communication with warm side heat exchanger 350. Outgoing heat fluid 360 is expelled from warm side heat exchanger 350 and directed to air-cooled heat exchanger 370. Fan 382 is an exemplary air-flow inducing device that is used to induce air-cooling to heat exchanger 370. Fluid 380 is expelled from air-cooled heat exchanger 370 back to warm side heat exchanger 350. In some embodiments, fan 382 may be omitted. In some embodiments, heat from fluid is dissipated using a heat exchanger where the environmental heat exchange occurs through other means such as liquid or phase-change heat exchange / transfer.
[0061] Turning now to cool side portions of the system, TE cold side contact plate 320 is associated with TE cold side 340. Cold side heat exchanger 390 cools and expels outgoing cooled fluid 317. Outgoing cooled fluid 317 is supplied to wearable system 311 (e.g., wearable thermal interface unit) which further comprises sensing elements 313. As described above with personalized adaptive thermal management system 200, sensing elements may include user-specific sensing elements and environment-specific sensing elements, including but not limited to motion, temperature, acceleration, humidity, light intensity, etc. After circulation through wearable system 311, heated fluid 312 is provided back to cold side heat exchanger 390.
[0062] Fluids 360, 380, 312, and 317 may be directed using fluid pumps, including micropump technology.
[0063] As depicted in FIG. 3, power, sensing, and control system (PSCS) 314 interfaces with TE warm side 330 and TE cold side 340, via connections 315, and is also connected to user interface unit 316 and wearable system 311 including sensing elements 313. Connections 315 between power, sensing, and control system 314 and TE warm side 330 and cold side 340 provide a capability for optimized control and operation of thermoelectric modules. PSCS 314 may utilize the computing system disclosed in FIGS. 1A and 1B to optimize the applicable cooling / heating mode.
[0064] Although only one thermoelectric module is shown, in certain embodiments, a plurality of thermoelectric modules may be deployed. The personalized adaptive thermal management system is configured to effectively and efficiently determine ideal operating parameters for the thermoelectric modules. In certain embodiments, contact plate 310 and / or contact plate 320 may be omitted.
[0065] The personalized adaptive thermal management system may utilize its components, alone or in combination, to enhance (maximize) machine learning efficiency, prolong battery operating life, enhance response time, and increase power to mass ratio.Dynamic Power Optimization
[0066] Thermoelectric modules, when used as cooling systems, have a very narrow window of high efficiency. Their performance declines quickly as temperature difference between their cold side and hot side exceed a few degrees Celsius and as their power intake exceeds above or drops below a certain power window.
[0067] The personalized adaptive thermal management system PSCS monitors the temperature on the hot and cold side of each TE module and adjusts the electric power (voltage) applied to each TE module based on the real-time temperature readings and the total cooling power requirement which is determined by another section of the PSCS. This ensures the delivery of the desired cooling power at any given time while maximizing the efficiency of the system. This feature enables the personalized adaptive thermal management system to prolong battery life per charge cycle and maximize total cooling power per unit mass of the system.
[0068] In one embodiment, the temperature of the hot sides and cold sides of an array of thermoelectric modules are monitored continuously. The array may include all thermoelectric modules in a given system or a subset of the thermoelectric modules for a given system. Average temperatures of the hot sides and cold sides are calculated, and an temperature difference between the average hot side and average cold side are calculated.
[0069] Because thermoelectric modules can be inefficient if not operating within an optimized ranged, the personalized adaptive thermal management system calculates an optimized voltage to be applied to the array of TE modules. The optimized voltage is the voltage which results in a maximum coefficient of performance (COP) based on the temperature difference between the average hot and average cold sides.
[0070] The array of TE modules may be in a series configuration or a parallel configuration. In parallel configuration, the optimized voltage is applied evenly across the array of TE modules. In series configured, the optimized voltage multiplied by the number of TE modules in the array is applied to the two ends of the TEC array.
[0071] COP is calculated as a function of voltage and temperature difference for each TEC model. In other words, COP=f(V, ΔT), Vopt=g(COPmax, ΔT, NTEC), and thus the optimal V may be calculated for any given ΔT to maximize COP.
[0072] In addition to controlling the overall heating and cooling of the system by applying a voltage to a given TE module or TE module array, personalized adaptive thermal management system may control overall heating and cooling by adjusting the pumping rate of micropumps and / or the speed of air-flow inducing fan (or its equivalent when the environmental heat exchange occurs through other means such as liquid or phase-shift).Hybrid Heat Dissipation for Ultra-Low Thermal Resistance
[0073] The personalized adaptive thermal management system may utilize a number of different of heat transfer mechanisms and systems to lower the temperature on the hot (warm) side of the TE modules and increase the efficiency and performance of the ATU and HEU systems. This may include optimized geometry to boost heat transfer and reduced thermal resistance, optimized fluid flow by adjusting the power applied to micropumps, adjustment of power applied to the fans, reducing resistance to fluid flow using non-wetting surfaces, and employing phase-change heat exchangers to reduce thermal resistance. Any one or combination of the aforementioned enhancements may be utilized.
[0074] Furthermore, at least the following heat transfer mechanisms may used to dissipate heat to the environment: Liquid microchannel cooling couple with air-cooled heat exchange to air, closed two-phase liquid-vapor system, closed two-phase system solid-liquid, open two-phase system liquid-vapor, open multiphase system, direct heat exchange with ambient (air, liquid, etc.), liquid cooling with heat exchange to surrounding water (for diving applications).
[0075] In addition to employing optimized power settings other the remaining components of the system are optimized for weight and power efficiency. For example, battery power provided to the unit may be provided by lithium-ion batteries which may optionally be charged by lightweight solar panels. Lightweight versions of sensors and materials may be employed to reduce the overall impact on the user and thus avoid a counter-productive increase in body temperature caused by excess exertion.

[0119] Deep Learning: Applying neural networks, especially recurrent neural networks (RNNs) or long short-term memory (LSTM) models, to capture complex temporal dependencies among the physiological signals.
[0120] By feeding the ML model with continuous data streams from the improved cooling vest's sensors, it can learn to recognize the onset of dangerous conditions early on. This proactive approach allows for immediate adjustments to cooling strategies and the initiation of alerts and emergency protocols, potentially saving lives by preventing heat stroke before it occurs.
[0121] Furthermore, the system's ability to communicate with external devices and services ensures that in case of a critical alert, detailed information about the wearer's condition and location can be instantly shared with emergency responders or caregivers, enhancing the efficiency of the response and the likelihood of a positive outcome.Component 10: Health Monitoring and Emergency Response
