Furthermore, prior art fails to include a virtual reality and augmented reality system that includes a feedback loop to moderate and influence cooling programs based on brain activity.
Many people suffer from anxiety, stress, depression, and other mental health conditions. These mental health conditions often affect the sleep and day-to-day performance of an individual. One method to help with these mental health conditions is meditation. Generally, meditation requires an individual to get comfortable, to focus on their breath and how their body moves with each inhale and exhale. This is challenging for individuals with busy daily schedules and/or noisy and crowded environments. Furthermore, many individuals need to be trained on how to meditate and require a teacher and/or step by step guidance on how to meditate. Currently, this typically requires attending in-person meditation classes or having accessing to a remote device, which is difficult to watch and hear in a noisy environment. One way to overcome this problem is to create an immersive virtual reality environment that provides audiovisual guidance so a wearer is able to successfully meditate. Therefore, there is a need for a virtual reality system that provides an immersive environment for meditation applications even in noisy environments.
Sometimes audiovisual cues are not enough to provide a completely immersive environment. To amplify the virtual reality environment, a feedback element is needed. Temperature related feedback elements are particularly beneficial for creating sensations for a wearer. Additionally, monitoring a wearer's temperature and creating a response based on the wearer's temperature improves the overall effectiveness of a virtual reality/augmented reality system. Therefore, there is a need for a virtual reality system that is operable to create an immersive environment using temperature related elements to provide feedback to a wearer.
The present invention includes a virtual reality system with temperature controlling elements to create an immersive environment to provide a relaxing and mediative environment. The virtual reality system includes a virtual reality headset that is operable to display virtual reality media including virtual reality images, scenes, movies and/or environments. The virtual reality system is further operable to change the displayed media based on the physiological condition of the wearer. Advantageously, this enables the present invention to adapt to a plurality of wearers and provide a unique immersive virtual reality environment for each wearer.
The virtual reality system is configured to block out external light and display an audiovisual representation to a wearer. The virtual reality system is configured to change the display based on the wearer's viewing direction and provide a full 360 degree virtual environment. Advantageously, the virtual reality system is configured to only play ether audio or visual data based on a wearer's preference.
Referring now to the drawings in general, the illustrations are for the purpose of describing one or more preferred embodiments of the invention and are not intended to limit the invention thereto.

The headset is configured to receive and display an image of a virtual scene, movie, and/or environment. The headset is further operable to receive audio data and communicate the audio data to a wearer via a speaker, headphones, and other similar audio playback devices. For example, and not limitation, the headset is configured to receive audiovisual data including a meditation class set at the beach. The headset is configured to display the beach environment via the display and play corresponding sounds as well as the voice of a teacher leading the meditation class via the audio playback device. In one embodiment, the headphones are noise-cancelling headphones. The noise-cancelling headphones are configured to block out external noise so a wearer is completely immersed in the virtual reality environment.
The virtual reality system is configured to provide a meditation exercise and a corresponding virtual reality environment based on a wearer's input and/or preferences. The meditation exercise includes audio instructions guiding the wearer through meditation steps.

In yet another embodiment, the headset covers a wearer's entire face.
In one embodiment, the at least one image capturing device is a motion sensor camera and is configured to capture a wearer's body movement. Alternatively, the image capturing device is a LIDAR camera. The virtual reality system is configured to use the captured motion data to determine a wearer's state of mind and whether the displayed virtual reality imagery needs to be changed. For example, if the motion capture data indicates that a wearer is restless then the virtual reality system is configured to display a peaceful scene (e.g. a calm day at the beach) and a corresponding calming noise (e.g. waves crashing). The at least one image capturing device is further operable to determine a wearer's posture and provide at least one recommendation to correct a wearer's posture based on the audiovisual display. The posture feedback is critical for meditation applications to ensure a wearer is in a proper meditation position.

In one embodiment, one or more of the at least one processor is operable to run predefined programs stored in at least one memory of the control electronics.
The control electronics preferably includes at least one antenna, which allows the control electronics to receive and process input data (e.g., temperature settings, virtual reality settings) from at least one remote device (e.g., smartphone, tablet, laptop computer, desktop computer, remote control). In a preferred embodiment, the at least one remote device is in wireless network communication with the control electronics.

Alternatively, the at least one remote device is in wired communication with the control electronics through USB or equivalent.
In one embodiment, the at least one processor is a microcontroller. The microcontroller includes a transceiver, BLUETOOTH module, WI-FI module, a microprocessor, an ultra-low-power co-processor, read-only memory (ROM), random-access memory (RAM) (e.g., static random-access memory (SRAM)), flash memory, a power management unit, a temperature sensor, and/or a digital-to-analog converter.
In yet another embodiment, the virtual reality system includes a temperature component configured to provide a heating or cooling effect to a wearer. In one embodiment, the headset includes waterproof tubing and a fluid reservoir. The temperature component includes a thermoelectric device that is configured to heat or cool the fluid reservoir. The headset is configured to heat or cool the fluid reservoir based on the wearer's needs or preferences and then move the fluid through the tubing to provide a cooling or heating effect to the wearer.
In another embodiment, the headset includes at least one fluid reservoir holding fluid to be circulated through the headset. The at least one fluid reservoir is positioned adjacent to at least one temperature component. The at least one temperature component includes at least one thermoelectric module containing at least one Peltier chip. In one embodiment, the at least one thermoelectric module contains four Peltier chips. When electricity is provided to the at least one thermoelectric module, the at least one Peltier chip causes heating or cooling of the at least one fluid reservoir. The at least one thermoelectric module is connected to a at least one heat sink via at least one heat tube. In one embodiment, the at least one heat sink includes a first heat sink and a second heat sink that are aligned along a common axis with space separating the first heat sink from the second heat sink. The at least one thermoelectric module is positioned such that it is not aligned along the common axis of the first heat sink and the second heat sink and such that the at least one thermoelectric module is not located in the space between the first heat sink and the second heat sink. When the at least one thermoelectric module is in cooling mode, heat is transferred away from the at least one thermoelectric module and toward the first heat sink and the second heat sink via the at least one heat tube. This transfer of heat increases the efficiency of the at least one thermoelectric module and prevents the at least one thermoelectric module from breaking down due to excessive heat buildup.
In one embodiment, the first heat sink and the second heat sink each include a plurality of fins, with the fins assisting in dissipating excess heat. The plurality of fins each extend perpendicularly outward from a base of each of the first heat sink and second heat sink. In one embodiment, the first heat sink is connected to at least one first fan and the second heat sink is connected to at least one second fan. When active, at least one first fan blows air over the first heat sink in a first direction and the at least one second fan sucks air from the second heat sink in the first direction, thereby creating a common air path along the common axis between the first heat sink and the second heat sink. The common air path increases the efficiency of the first heat sink and the second heat sink. Additionally, because the at least one thermoelectric module is positioned such that it is not aligned along the common axis of the first heat sink and the second heat sink, and is therefore not in the common air path, air possessing residual heat from the first heat sink and the second heat sink is not blown directly over the at least one thermoelectric module.
In one embodiment, the first heat sink and the second heat sink are connected by a chassis, which acts as an electromagnetic field (EMF) shield. In one embodiment, the chassis is a strip having approximately the same thickness as the first heat sink and second heat sink. In another embodiment, the chassis substantially surrounds the interior of the control electronics. In one embodiment, the chassis is formed from one or more sheet metals, such as copper, aluminum, cobalt, brass, nickel, silver, steel, tin, or other metals able to act as a shield to EMF radiation. In another embodiment, the chassis is formed from a metal foam or from a conductive non-metal fabric capable of stopping EMF radiation, such as nylon coated or interwoven with a conductive metal material.
EMF radiation has been shown, in some cases, to increase the quantity of melatonin produced during sleep, which potentially causes a poorer quality of sleep. In addition, individuals have been shown to experience symptoms including headaches, nausea, and fatigue when exposed to EMF radiation, especially over longer periods of time. Therefore, the inclusion of the chassis in the control electronics helps prevent prolonged exposure to wearers of EMF radiation produced by the control electronics operation, which otherwise disrupts a wearer's meditation, sleep or cause other adverse symptoms.
Alternatively, the headset includes a plurality of thermoelectric temperature regulators arranged across the virtual reality headset, a controller configured to apply power to cool the thermoelectric temperature regulators to between about 1° C. and about 30° C., and a holding mechanism configured to secure the headset to the wearer's face and/or forehead. In one embodiment, the controller is configured to control the applied temperature during an active cooling phase for a predetermined time period (e.g., 10 minutes to 60 minutes, 10 minute to 45 minutes, etc. or any time between 10 minutes and 3 hours, selected by the wearer via a remote device or the headset or automatically determined), or until the headset detects that the wearer is asleep. The headset is then operable to toggle into a standby state and regulate the temperature at a standby temperature (e.g., between about 26° C. and about 38° C., between about 28° C. and about 38° C., between 30° C. and 38° C., etc. or within a few degree, e.g., +/−2° C., of body surface/skin temperature). In some variations, the headset is configured to apply the cooling in a ramp with decreasing temperature (e.g., decreasing from 30° C. or 25° C.) until the wearer experiences a diving reflex, at which point the temperature is sustained for a predetermined first treatment time period (e.g., 10 minutes to 60 minutes, 10 minute to 45 minutes, etc. or any time between 10 minutes and 3 hours).
In another embodiment, the controller is configured to apply energy in a pulsatile manner so that the thermoelectric temperature regulators apply variable cooling to the wearer's face (e.g., varying between the cooling temperature and a temperature that is slightly higher than the cooling temperature). For example, the controller is configured to apply the energy in pulses having a pulse duration of less than 360 seconds.
An example of a cooling headband is disclosed in U.S. Patent No. 2017/0333667, which is incorporated herein by reference in its entirety.
In yet another embodiment, the virtual reality system is operable to receive wearer voice input data. The virtual reality system includes a microphone that is operable to receive and record a wearer's voice. The headset is further operable to change the audiovisual display and/or the temperature component based on the wearer's words. For example, and not limitation, the virtual reality system is configured to receive the words “Too Hot” from a wearer, and activate the cooling element of the temperature component.
Additionally, the virtual reality system further comprises a sensory feedback device such as a lamp, which is electrically wired or connected to the headset. The lamp is operable to provide haptic feedback based on the audiovisual display. For example, and not limitation, the lamp is configured to generate a light on a wearer to simulate sunlight and heat. In another embodiment, the virtual reality system includes an actuator. The virtual reality system is configured to activate the actuator to provide haptic feedback based on wearer data captured by at least one sensor. For example, and not limitation, the virtual reality system is operable to determine that a wearer has poor posture during a mediation exercise and then activate the actuator until the wearer has good posture. In yet another embodiment, the virtual reality system is configured to provide temperature feedback based on the wearer's data. For example, and not limitation, the virtual reality system is configured to generate a cooling effect when the virtual reality system detects that a wearer is sweating, overheating, experiencing an elevated heart rate, increased stress levels and/or other similar symptoms.
In one embodiment, the headset is further configured to work with a sleep and promotion system as disclosed in US Patent Publication No. 20180110960, which is incorporated herein by reference in its entirety.
In one embodiment, the headset includes an AC power input voltage between about 100V to about 240V with about 50-60 Hz and about 3 A. In yet another embodiment, the headset includes a DC power of 12 VDC and 1 Mbps. In another embodiment, the headset is operable to function between about 14° C. to about 24° C. (57° F. to 75° F.) and about 15% to about 75% relative humidity, non-condensing.
In another embodiment, the headset includes control electronics configured to determine if the device is too cold and/or too warm and is configured to shut down the headset based on the temperature of the headset. The control electronics is further configured to monitor current through the headset. In one embodiment, the headset includes cooling engines as well as thermistors. The headset includes at least one sensor configured to measure the cold side temperature of each thermistor. The headset further includes a fan and thermoelectric cooling (TEC) current sensors, and is configured to monitor battery voltage and battery temperature. In yet another embodiment, two cooling engines are made of a TEC sensor mounted to a heatsink. The fan is configured to dissipate heat from the cooling engines.

In yet another embodiment, two thermoelectric coolers are wired in parallel. In one embodiment, the virtual reality system includes a heat sink including a black anodized extruded aluminum sink that is configured to dissipate heat from the thermoelectric cooler. The present invention further includes a thermal tape to attach the thermoelectric cooler to the heatsink and transfer excessive heat from the outside of the thermoelectric cooler to the heat sink. In one embodiment, the present invention includes two fans connected in parallel. Alternatively, the fans are connected in series.
In one embodiment, the battery assembly includes a USB C connector and reversible connector diodes for electrostatic discharge (ESD) protection. In yet another embodiment, the headset includes a noise dampening and/or cancelling component that is configured to reduce noise produced by the cooling assemblies.

As illustrated in
From the reservoir, the temperature conditioned fluid exits through the outlet and enters the conduit assembly formed from an arrangement of in-housing Z-, L-, 7-, and S-shaped tubes (and joints). A pump is operatively connected to the reservoir and functions to circulate the fluid through the control unit 10 in a circuit including the in-housing tubes (and joints), flexible fluid supply line 16, silicone pad tubes, fluid return line 17, and back into the reservoir through fluid return. In one embodiment, the control unit includes an insulated linear heat tube located outside of the fluid reservoir and inside the housing. The insulated linear heat tube communicates with the conduit assembly to selectively heat fluid moving from the control unit 10 to the temperature-regulating headset. The exemplary heat tube is operable to heat fluid moving in the hydraulic circuit to a desired temperature as warm as 47.78° C. (118° F.).
The control unit has at least one fluid reservoir. In one embodiment, the control unit includes two fluid reservoirs. A first fluid reservoir is used to heat and/or cool fluid that circulates through the temperature-regulated headset. The first fluid reservoir includes at least one sensor to measure a level of the fluid. A second fluid reservoir is used to store fluid. In a preferred embodiment, fluid from the second fluid reservoir is automatically used to fill the first fluid reservoir when the at least one sensor indicates that the level of the fluid is below a minimum value. Advantageously, this optimizes the temperature in the first fluid reservoir because only a small amount of stored fluid is introduced into the first fluid reservoir when needed. Additionally, this embodiment reduces the refilling required for the control unit, saving the wearer time and effort. In one embodiment, the at least one fluid reservoir is formed of metal. In another embodiment, the metal of the at least one fluid reservoir is electrically connected to ground.
In another embodiment, the control unit includes at least one fluid reservoir holding fluid to be circulated through a temperature-regulated headset. The at least one fluid reservoir is positioned adjacent to at least one thermoelectric module containing at least one Peltier chip. In one embodiment, the at least one thermoelectric module contains four Peltier chips. When electricity is provided to the at least one thermoelectric module, the at least one Peltier chip causes heating or cooling of the at least one fluid reservoir. The at least one thermoelectric module is connected to a first heat sink and a second heat sink via at least one heat tube. In one embodiment, the first heat sink and the second heat sink are aligned along a common axis with space separating the first heat sink from the second heat sink. The at least one thermoelectric module is positioned such that it is not aligned along the common axis of the first heat sink and the second heat sink and such that the at least one thermoelectric module is not located in the space between the first heat sink and the second heat sink. When the at least one thermoelectric module is in cooling mode, at least one heat tube operates to transfer heat away from the at least one thermoelectric module and toward the first heat sink and the second heat sink. This transfer of heat increases the efficiency of the at least one thermoelectric module and prevents the at least one thermoelectric module from breaking down due to excessive heat buildup.
Furthermore, in one embodiment, the control unit includes a partition, separating the common air path from the at least one fluid reservoir. Including the partition helps to ensure that the temperature of the at least one fluid reservoir is not directly affected by the temperature of the air, which decreases the thermal efficiency of the device.
In another embodiment, the thermoelectric module includes at least one first Peltier chip that is separated from at least one second Peltier chip. The at least one first Peltier chip heats and/or cools fluid traveling to a first location, while the at least one second Peltier chip heats and/or cools fluid traveling to a second location, such that the at least one first Peltier chip is part of an independent thermal regulation loop than the at least one second Peltier chip. Separating the at least one first Peltier chip and the at least one second Peltier chip allows the control unit to regulate two different articles at different temperatures. For example and not limitation, the control unit is configured to simultaneously regulate two virtual reality headsets at different temperatures.

The predefined programs 740 are general virtual reality settings for virtual reality applications. For example, and not limitations, the virtual reality applications include meditation applications, relaxation applications, sleep applications and other similar applications designed to create a physiological effect of the wearer via an immersive virtual environment. Advantageously, the predefined programs 740 are designed for various conditions and/or body types (e.g., weight loss, comfort, athletic recovery, anxiety, depression, alternative sleep cycles). In one embodiment, a meditation program sets a skin temperature at a very cold setting (e.g., 15.56-18.89° C. (60-66° F.)) to decrease brain activity, which then helps a wearer meditate and/or sleep.

In still another embodiment, temperature modulation cycles are used to reduce sleep disruptions due to multiple sclerosis (MS). In MS, core temperature and extremity temperature management are not consistent. As a result, a warm to sleep and warm to wake is suggested. In one example, the surface temperature is 37.78° C. (100° F.) at the start of a sleep period, 21.11° C. (70° F.) during N1-N2 sleep, 20° C. (68° F.) during N3 sleep, 26.67° C. (80° F.) during REM sleep, and 37.78° C. (100° F.) to wake the wearer.
In yet another embodiment, temperature modulation cycles are used to support wearers with alternative sleep cycles. An alternative sleep cycle is when a wearer changes to a multiple phase sleep cycle in a 24-hour cycle (e.g., biphasic, segmented, polyphasic sleep). In one example, the surface temperature is 21.11° C. (70° F.) at the start of a sleep period, 17.78° C. (64° F.) during N1-N2 sleep, 16.67° C. (62° F.) during N3 sleep, 19.44° C. (67° F.) during REM sleep, and 21.11° C. (70° F.) to wake the wearer. This program repeats for multiple, evenly spaced sleep blocks or be used in a longer block of 4-5 hours. For a short 30-minute block, the temperature drops (e.g., 0.278° C./minute (0.5° F./minute) or greater).
The temperature modulation cycles alternate cooling and heating based on automated collection of risk factors, including temperature, surface area pressure, and moisture (e.g., sweat). In another embodiment, temperature modulation cycles are prescribed by a sleep specialist or physician based on a particular health condition of a wearer.
The custom wellness programs 741 are virtual reality settings defined by the wearer. The virtual reality settings include eye sensitivity, motion sickness factors, noise levels, and camera speed settings. In one example, the wearer creates a custom program by modifying a predefined program (e.g., the meditation program above) to be 1.11° C. (2° F.) cooler during the meditation application. In another example, the wearer creates a custom program by modifying a predefined program (e.g., the meditation program) to have a start temperature of 37.78° C. (100° F.). In yet another example, the wearer creates a custom program by modifying the display settings. For example, and not limitation, the display movement, the rate of display movement, and whether any audio should be played is modifiable by the wearer. The custom wellness programs 741 allow a wearer to save preferred virtual reality settings. For example, and not limitation, the custom wellness programs include visual fitness programs, interval training, yoga training, and group training.

In one embodiment, based on a selected virtual environment displayed by the virtual reality system, the virtual reality system transmits messages to the at least one fluid control unit to modulate temperature of the at least one thermoregulated article to match the virtual environment. By way of example and not limitation, if the rendered virtual environment shows the user in the middle of the Savannah, the at least one thermoregulated article increases in temperature to approximate the feeling of being in the Savannah. Contrastingly, if the rendered virtual environment shows the user on a windy beach or on a rainy dock, the at least one thermoregulated article decreases in temperature. In one embodiment, the at least one thermoregulated article is regulated to match the user's precise position in the virtual environment. For example, if the user is in a sunny environment, but under a tree, with only the user's face not in the shade, a pillow is increased in temperature (along with virtual reality system itself), while a mattress pad, mattress, or blanket is kept at a relative normal temperature. By using temperature to match a user's virtual environment, the virtual reality system is better able to immerse the user in the environment, increasing comfort and improving meditation.
