The illustrative embodiments provide a system, method, and wireless earpieces for utilizing radar to detect user biometrics, identifying the user, and providing contextual awareness. In one embodiment, the wireless earpieces may be worn to provide media content to a user and may also capture user biometrics utilizing any number of sensors. The sensors may include a radar sensor that may be utilized to detect biometrics, such as heart rate, blood pressure, blood oxygenation, heart rate variability, blood velocity, and so forth. The radar sensor may also detect the orientation, location, motion, and distances of the wireless earpieces as well as the wireless earpieces relative to other electronic devices (e.g., paired, linked, communicating devices, etc.). The wireless earpieces may represent any number of shapes and configurations, such as wireless earbuds or a wireless headset.
The radar sensor may be configured as an active, passive, or combination sensor. In various embodiments, the radar sensor may be internally or externally focused. For example, internally focused radar sensors may perform any number of measurements, readings, or functions including, but not limited to, measuring/tracking the motion and orientation of a user or other target/body (e.g., translational, rotational displacement, velocity, acceleration, etc.), determining material properties of a target/body (e.g., glass, steel, wood, density, etc.), and determining a physical structure of a target/body (e.g., layer analysis, depth measurements, material composition, external and internal shape, construction of an object, etc.). The specific measurements of the wireless earpieces may be focused on user biometrics, such as heart rate, blood flow velocity, status of the wireless earpieces (e.g., worn, in storage, positioned on a desk, etc.), identification of the user, and so forth. The utilization of radar in the wireless earpieces may be beneficial because of insensitivity to ambient light, skin pigmentation, and because direct sensor-user contact is not required. The utilization of radar sensors may also allow the sensors to be completely encapsulated, enclosed, or otherwise integrated in the wireless earpieces shielding the radar sensors from exposure to sweat/fluids, water, dirt, and dust.
The illustrative embodiments may utilize the Doppler frequency of the blood flow velocity determined from a composite signal detected by the sensors of the wireless earpieces. Utilization of radar sensors may provide for more reliable detection of whether the wireless earpieces are being worn in the ears of the user. The wireless earpieces may also self-determine a location, such as in a pocket, on a desk, in a hand, in a bag, in a smart charger, within a container, or so forth. The location determined by the radar sensors may also be synchronized with a wireless device in the event the user forgets or misplaces the wireless earpieces so that a record of the last known position or estimated position is recorded.
The illustrative embodiments may also determine whether the user is an authorized user utilizing a radar signature determined by the radar sensors. For example, the radar sensors may determine the size and shape of the users inner and outer ear as well as other facial structures, such as cheek shape, jaw bone and muscle arrangements, and so forth. In addition, the wireless earpieces may be utilized alone or as a set. When utilized as a set, the signals or determinations may be combined to determine information, such as the orientation of the left wireless earpiece and the right wireless earpiece relative to one another and the user's head, distance between the wireless earpieces, motion of the wireless earpieces relative to one another and the user's head, and so forth. In one embodiment, the radar measurements may measure physiological parameters from which a pulsatile component (e.g., heart rate) may be determined.
The illustrative embodiments may also be applicable to any number of other wearable devices, systems, or components, such as smart watches, headsets, electronic clothing/shoes, anklets, or so forth. As noted, both internally facing (toward the user) and externally facing radar sensors may be utilized. The wireless earpieces may communicate with any number of communications or computing devices (e.g., cell phones, smart helmets, vehicles, emergency beacons, smart clothing, emergency service personnel, designated contacts, etc.).
The radar sensors may utilize continuous wave and pulsed wave communications (active detection) as well as ambient environmental signals, such as Wi-Fi, Bluetooth, and so forth. For example, a Doppler signal may be utilized to detect a heart rate based on detected motion (e.g., rotation, displacement, deformation, acceleration, fluid-flow velocity, vortex shedding Poiseuille's law, Navier Stoke's equations, etc.).
The headphones 107 may include sensors that are not within the ear canal. The headphones 107 may include sensors that are integrated with an over-head support, ear pads/cups, a frame, or so forth. The biometrics may be measured from the user's head (e.g., ears, neck, ears, scalp, skin, etc.) or body. The information may also be associated with the environment, user activity/actions, ambient, or so forth.
In one embodiment, the wireless earpieces 102 includes a housing or frame 108 shaped to fit substantially within the ears of the user 106. The housing or frame 108 is a support structure that at least partially encloses and houses the electronic components of the wireless earpieces 102. The frame 108 may be composed of a single structure (e.g., plastic or composite molding) or multiple structures that are interconnected. The frame 108 protects the components of the wireless earpieces 102 and may flex or deform slightly when dropped on or stepped on to protect the internal components. An exterior portion of the wireless earpieces 102 may include a first set of sensors shown as infrared sensors 109. The infrared sensors 109 may include emitter and receivers that detects and measures infrared light radiating from objects in its field of view. The infrared sensors 109 may detect gestures, touches, or other user input against an exterior portion of the wireless earpieces 102 that is visible when worn by the user 106. The infrared sensors 109 may also detect infrared light or motion. The infrared sensors 109 may be utilized to determine whether the wireless earpieces 102 are being worn, moved, approached by a user, set aside, stored in a smart case, placed in a dark environment, or so forth.
The frame 108 defines an extension 110 configured to fit substantially within the ear of the user 106. The extension 110 may include one or more speakers or vibration components for interacting with the user 106. All or portions of the extension 110 may be removable covered by one or more sleeves. The sleeves may be changed to fit the size and shape of the user's ears. The sleeves may come in various sizes and have extremely tight tolerances to fit the user 106 and one or more other users that may utilize the wireless earpieces 102 during their expected lifecycle. In another embodiment, the sleeves may be custom built to support the interference fit utilized by the wireless earpieces 102 while also being comfortable while worn. The sleeves are shaped and configured to not cover various sensor devices of the wireless earpieces 102.
In one embodiment, the frame 108 or the extension 110 (or other portions of the wireless earpieces 102) may include sensors 112 for sensing heart rate, blood oxygenation, temperature, heart rate variability, blood velocity, voice characteristics, skin conduction, glucose levels, impacts, activity level, position, motion, particulates, chemical content, location, orientation, as well as any number of internal or external user biometrics. The sensors 112 may be partially or completely encompassed or integrated with the frame 108 or the extension 110. In other embodiments, the sensors 112 may be positioned to contact or be proximate the epithelium of the external auditory canal or auricular region of the user's ears when worn. For example, the sensors 112 may represent various metallic sensor contacts, optical interfaces, radar, or even micro-delivery systems for receiving, measuring, and delivering information and signals. Small electrical charges, the Doppler effect, or spectroscopy emissions (e.g., various light wavelengths) may be utilized by the sensors 112 to analyze the biometrics of the user 106 including pulse, blood pressure, skin conductivity, blood analysis, sweat levels, and so forth. In one embodiment, the sensors 112 may include optical sensors that may emit and measure reflected light within the ears of the user 106 to measure any number of biometrics. The optical sensors may also be utilized as a second set of sensors to determine when the wireless earpieces 102 are in use, stored, charging, or otherwise positioned.
In one embodiment, the sensors 112 may include a radar sensor 114 (the sensors 112 and the radar sensor 114 may also be included in the headphone 107). The radar sensor 114 may be at least partially enclosed or encompassed within a housing or frame 108. The radar sensor 114 may detect gestures or micro gestures performed by the user. In another embodiment, the radar sensor 114 may be a separate sensing component proximate the sensors 112 or positioned at one or more locations proximate the skin or tissue of the user. The radar sensor 114 may utilize any number of radar signals, bands, waves, or technologies (e.g., Google's Developing Project Soli). For example, the radar sensor 114 may operate at approximately 60 GHz and scanning at 10 frames per second. In some embodiments, the signal frequency/band (e.g., IEEE HF, VHF, UHF, L, S, C, X K, Ku, Ka, mm, V, W, F, D, G, Y, J, etc.), scanning interval, and other variables may be automatically configured, manually set, or set based on application. For example, the radar sensor 114 may include Hz, kHz, MHz, GHz, millimeter-wave, and/or terahertz radar systems. The radar sensor 114 may implement an important role in multimodal layered sensing systems targeted at measuring both physiological and behavioral biometric data. The illustrative embodiments may utilize the radar sensor 114 to detect blood pressure, heart rate variability, blood velocity, user identification, and so forth. The radar sensor 114 of both the left wireless earpiece and the right wireless earpiece may work in combination to ensure accurate readings are performed. The wireless earpieces 102 may utilize mathematic, error correction, and measurement processes, such as averaging, sampling, medians, thresholds, or so forth to ensure that all measurements by the radar sensors 113 are accurate. The radar sensor 114 may include logic, memory, transmitters, receivers, antennas (e.g., two or more), amplifiers, circuits, filters, interfaces, ports, connectors and so forth.
The sensors 112 may be utilized to provide relevant information that may be communicated through the wireless earpieces 102. As described, the sensors 112 may include one or more microphones that may be integrated with the frame 108 or the extension of the wireless earpieces 102. For example, an external microphone may sense environmental noises as well as the user's voice as communicated through the air of the communications environment 100. An ear-bone or internal microphone may sense vibrations or sound waves communicated through the head of the user 102 (e.g., bone conduction, etc.).
In some applications, temporary adhesives or securing mechanisms (e.g., clamps, straps, lanyards, extenders, etc.) may be utilized to ensure that the wireless earpieces 102 remain in the ears of the user 106 even during the most rigorous and physical activities or to ensure that if they do fall out, the wireless earpieces 102 are not lost or broken. For example, the wireless earpieces 102 may be utilized during marathons, swimming, team sports, biking, hiking, parachuting, or so forth. In one embodiment, miniature straps may attach to the wireless earpieces 102 with a clip on the strap securing the wireless earpieces to the clothes, hair, or body of the user. The wireless earpieces 102 may be configured to play music or audio, receive and make phone calls or other communications, determine ambient environmental conditions (e.g., temperature, altitude, location, speed, heading, etc.), read user biometrics (e.g., heart rate, motion, temperature, sleep, blood oxygenation, voice output, calories burned, forces experienced, etc.), and receive user input, feedback, or instructions. The wireless earpieces 102 may also execute any number of applications to perform specific purposes. The wireless earpieces 102 may be utilized with any number of automatic assistants, such as Siri, Cortana, Alexa, Google, Watson, or other smart assistants/artificial intelligence systems.
The communications environment 100 may further include the personal computer 118. The personal computer 118 may communicate with one or more wired or wireless networks, such as a network 120. The personal computer 118 may represent any number of devices, systems, equipment, or components, such as a laptop, server, tablet, medical system, gaming device, virtual/augmented reality system, or so forth. The personal computer 118 may communicate utilizing any number of standards, protocols, or processes. For example, the personal computer 118 may utilize a wired or wireless connection to communicate with the wireless earpieces 102, the wireless device 104, or other electronic devices. The personal computer 118 may utilize any number of memories or databases to store or synchronize biometric information associated with the user 106, data, passwords, or media content.
The wireless earpieces 102 may determine their position with respect to each other as well as the wireless device 104 and the personal computer 118. The components of the sensors 112 as well as the sensors of the wireless device 104 and the personal computer may be utilized to determine relative position, orientation, motion, and so forth. For example, position information for the wireless earpieces 102 and the wireless device 104 may determine proximity of the devices in the communications environment 100. For example, global positioning information, radar measurements, or signal strength/activity may be utilized to determine proximity and distance of the devices to each other in the communications environment 100. In one embodiment, the distance information may be utilized to determine whether biometric analysis may be displayed to a user. For example, the wireless earpieces 102 may be required to be within four feet of the wireless device 104 and the personal computer 118 in order to display biometric readings or receive user input. The transmission power or amplification of received signals may also be varied based on the proximity of the devices in the communications environment 100.
In one embodiment, the wireless earpieces 102 and the corresponding sensors 112 (whether internal or external) may be configured to take a number of measurements or log information and activities during normal usage. This information, data, values, and determinations may be reported to the user or otherwise utilized as part of the virtual assistant. The sensor measurements may be utilized to extrapolate other measurements, factors, or conditions applicable to the user 106 or the communications environment 100. For example, the sensors 112 may monitor the user's usage patterns or light sensed in the communications environment 100 to enter a full power mode in a timely manner. The user 106 or another party may configure the wireless earpieces 102 directly or through a connected device and application (e.g., mobile app with a graphical user interface) to set power settings (e.g., preferences, conditions, parameters, settings, factors, etc.) or to store or share biometric information, audio, and other data. In one embodiment, the user may establish the light conditions or motion that may activate the full power mode or that may keep the wireless earpieces 102 in a sleep or low power mode. As a result, the user 106 may configure the wireless earpieces 102 to maximize the battery life based on motion, lighting conditions, and other factors established for the user. For example, the user 106 may set the wireless earpieces 102 to enter a full power mode only if positioned within the ears of the user 106 within ten seconds of being moved, otherwise the wireless earpieces 102 remain in a low power mode to preserve battery life. This setting may be particularly useful if the wireless earpieces 102 are periodically moved or jostled without being inserted into the ears of the user 106. Any of the sensors 112 including the radar sensor 114 may be utilized to perform the respective determinations.
The user 106 or another party may also utilize the wireless device 104 to associate user information and conditions with the user preferences. For example, an application executed by the wireless device 104 may be utilized to specify the conditions (e.g., user biometrics read by the sensors 112) that may “wake up” the wireless earpieces 102 to automatically or manually communicate information, warnings, data, or status information to the user. Initial readings may also be recorded by the sensors 112 to create an identification and authorization profile including data, information, and measurements. The measurements may include voice analysis, height analysis, skin reflectivity, skin conductivity, radar profile, optical profile, and so forth. For example, the radar sensor 114 may be utilized to create a radar profile of the user's ear/head for automatically identifying the user when wearing the wireless earpieces 102. In addition, the enabled functions or components (e.g., sensors, transceivers, vibration alerts, speakers, lights, etc.) may be selectively activated based on the user preferences as set by default, by the user, or based on historical information. In another embodiment, the wireless earpieces 102 may be adjusted or trained over time to become even more accurate in adjusting to authentication information, habits, requirements, requests, activations, or other processes or functions performed by the wireless earpieces 102 for the user (e.g., applications, virtual assistants, etc.).
The wireless earpieces 102 may utilize historical information to generate default values, baselines, thresholds, policies, or settings for determining when and how various communications, actions, and processes are implemented. As a result, the wireless earpieces 102 may effectively manage the automatic and manually performed processes of the wireless earpieces 102 based on automatic detection of events and conditions (e.g., light, motion, user sensor readings, etc.) and user specified settings. For example, the authorization information may be utilized to subsequently identify the user and perform authentication.
As previously noted, the wireless earpieces 102 may include any number of sensors 112 and logic for measuring and determining user biometrics, such as pulse rate, skin conduction, blood oxygenation, blood velocity, skin/tissue/organ displacement, blood pressure, heart rate variability, blood velocity, temperature, calories expended, blood or excretion chemistry, voice and audio output, position, and orientation (e.g., body, head, etc.). The sensors 112 may also determine the user's location, position, velocity, impact levels, and so forth. Any of the sensors 112 may be utilized to detect or confirm light, motion, or other parameters that may affect how the wireless earpieces 102 manage, utilize, and initialize various processes, components, and functions. The sensors 112 may also receive user input and convert the user input into commands or selections made across the personal devices of the personal area network. For example, the user input detected by the wireless earpieces 102 may include voice commands, head motions, finger taps, finger swipes, motions or gestures, or other user inputs sensed by the wireless earpieces. The user input may be determined by the wireless earpieces 102 and converted into authorization commands that may be sent to one or more external devices, such as the wireless device 104, the personal computer 118, a tablet computer, or so forth. For example, the user 106 may create a specific head motion and voice command that when detected by the wireless earpieces 102 are utilized to send a request (implemented by the wireless earpiece or wireless earpieces 102/wireless device 104) to provide the user information or options, such as her current heart rate, speed, approaching objects, and location. In another example, the sensors 112 may prepare the wireless earpieces for an impact in response to determining the wireless earpieces 102 are free falling or have been dropped (e.g., device power down, actuator compression/shielding of sensitive components, etc.).
The sensors 112 may make all of the measurements with regard to the user 106 and communications environment 100 or may communicate with any number of other sensory devices, components, or systems in the communications environment 100. In one embodiment, the communications environment 100 may represent all or a portion of a personal area network. The wireless earpieces 102 may be utilized to control, communicate, manage, or interact with a number of other wearable devices or electronics, such as smart glasses, helmets, smart glass, watches or wrist bands, other wireless earpieces, chest straps, implants, displays, clothing, or so forth.

The network 120 may communicate with or include a wireless network, such as a Wi-Fi, cellular (e.g., 3G, 4G, 5G, PCS, GSM, etc.), Bluetooth, or other short range or long range radio frequency networks, signals, connections, or links. The network 120 may also include or communicate with any number of hard wired networks, such as local area networks, coaxial networks, fiber-optic networks, network adapters, or so forth. Communications within the communications environment 100 may be operated by one or more users, service providers, or network providers.
The wireless earpieces 102 may play, display, communicate, or utilize any number of alerts or communications to indicate that the actions, activities, communications, mode, or status in use or being implemented. For example, one or more alerts may indicate when various processes are implemented automatically or manually selected by the user. The alerts may indicate when actions are in process, authorized, and/or changing with specific tones, verbal acknowledgements, tactile feedback, or other forms of communicated messages. For example, an audible alert and LED flash may be utilized each time the wireless earpieces 102 receive user input. Verbal or audio acknowledgements, answers, and actions utilized by the wireless earpieces 102 are effective because of user familiarity with such devices in standard smart phone and personal computers. The corresponding alert may also be communicated to the user 106, the wireless device 104, and the personal computer 118.
In another embodiment, the wireless earpieces 102 may communicate a proximity, status change, location, or orientation alert based on the measurements performed by the sensors 112. For example, if the heart rate has changed significantly (e.g., dangerous thresholds exceeded—low or high), an alert may be sent to the user 106 or to one or more connected devices (e.g., wireless device 104, computer 118, etc.). In another example, an alert may be played in response to an approaching object. The alerts may be utilized with any number of other systems to protect or assist the user.
In other embodiments, the wireless earpieces 102 may also vibrate, flash, play a tone or other sound, or give other indications of the actions, status, or process implemented. The wireless earpieces 102 may also communicate an alert to the wireless device 104 that shows up as a notification, message, or other indicator indicating changes in status, actions, commands, or so forth. The type of alert may be specific to the indicated status, action, command or so forth. For example, user preferences may allow the user to specify how and when each alert is utilized.
The wireless earpieces 102 as well as the wireless device 104 may include logic for automatically implementing the virtual assistant in response to motion, light, user activities, user biometric status, user location, user position, historical activity/requests, or various other conditions and factors of the communications environment 100. The virtual assistant may be activated to perform a specified activity or to “listen” or be prepared to “receive” user input, feedback, or commands for implementation by the virtual assistant.

As noted, the layout of the internal components of the wireless earpieces 102 and the limited space available for a product of limited size may affect where the sensors 112 may be positioned. The positions of the sensors 112 within each of the wireless earpieces 102 may vary based on the model, version, and iteration of the wireless earpiece design and manufacturing process.

In one embodiment, the process begins by activating radar of the wireless earpieces (step 502). The radar may represent Doppler or optical radar utilizing any number of signals (e.g., pulse, continuous, etc.). In one embodiment, the radar sensors or units of the wireless earpieces may be activated whenever the wireless earpieces are turned on (e.g., not in a power save, low power, or charging mode). In other embodiments, a specific function, application, user request, or other automated or manual process may initiate, power-on, or otherwise activate the radar of the wireless earpieces. In one embodiment, the radar sensors of the wireless earpieces worn in-ear may be positioned within the external auditory canal. In another embodiment, the radar sensors of the wireless earpieces may be integrated in headphones worn by the user and may read measurements from the user's ear, neck, head, or other portions of the body of the user.
Next, the wireless earpieces perform radar measurements of the user (step 504). Each of the wireless earpieces may include one or more radar sensors or units performing radar measurements. In one embodiment, each radar unit may send a signal and receive back the reflections. In another embodiment, distinct radar units (whether within a single wireless earpiece or utilized between the different wireless earpieces) may send radar signals and receive the reflections or echoes. In one embodiment, the radar sensors may be directed toward one or more different portions of the user's ear, head, or body.
Next, the wireless earpieces analyze the radar measurements (step 506). The radar measurements may be analyzed or otherwise processed by a logic engine or processor. In one embodiment, the radar measurements are utilized to determine pulsatile measurements, such as heart rate, change in heart rate, blood flow velocity, and so forth. The measurements parameters may also include motion, such as rotation, displacement, deformation, acceleration, fluid-flow velocity, vortex shedding Poiseulle's law of fluid flow, Navier Stoke's equations, and so forth. For example, the radar sensors may measure the displacement of vessel walls. The radar sensors may measure the movement and volume of the residual component of the external auditory canal. The measurements may be detected in the received signal. The radar measurements may be converted to data, information, values, graphics, charts, visuals, or other information that may be communicated audibly through the wireless earpieces to a communications or computing devices. For example, biometric information, values, and data retrieved through analysis may be communicated to the user. During step 506, the radar sensors may detect changes in the received/reflected signal to determine amplitude, phase, phase angle and other applicable information (e.g., backscatter analysis). The analysis may determine the position, location, and orientation of the user and the wireless earpieces relative to each other and the user.
Next, the wireless earpieces generate pulsatile measurements based on the radar measurements (step 508). The pulsatile measurements may relate to the operation of the heart/body of the user and may include extensive biometric information. The biometric information may be generated from each of the wireless earpieces or may represent combined measurements from multiple wireless earpieces including one or more radar sensors/units. The biometric information may include heart rate, heart rate variability, blood flow velocity, blood oxygenation, blood pressure, stridor level, cerebral edema, respiration rate, excretion levels, ear/face/body structure, and other user biometrics.

The radar sensors may be utilized in conjunction with accelerometers, gyroscopes, thermistors, optical sensors, magnetometers, pressure sensors, environmental sensors, microphones, and so forth.
Next, the wireless earpieces send one or more communications based on the biometric information (step 510). The wireless earpieces may communicate the biometric information utilizing audible notices (e.g., your heart rate variability is ______, your blood pressure is ______, etc.), sounds, alerts, tactile feedback, light emissions (e.g., LEDs, touch screens, etc.). The communications may be to the user wearing the wireless earpieces or to specified users and devices.
The process of
Next, the wireless earpieces process the radar measurements (step 604). In one embodiment, the wireless earpieces may utilize internal processors, logic, circuits, or so forth to process the radar measurements. The radar sensors/units may also be configured to dynamically adjust signals based on the conditions, user, environment, noise levels, and so forth and to correspondingly process the radar measurements. During step 604, the radar measurements may be processed for communication or display by the wireless earpieces or any number of other devices in communication with the wireless earpieces. For example, the radar measurements may include biometric readings, such as pulsatile measurements, wireless earpiece position, orientation, and motion (e.g., relative to the user, each other, etc.).
During step 604, the wireless earpieces may determine whether there is a condition or event that should be communicated to the user/connected device, logged, recorded, or streamed, or otherwise processed. In one embodiment, user preferences, settings, parameters, thresholds, conditions, or other information may be utilized to determine whether an action should be performed. For example, the radar sensors may determine that the user may have fallen based on the detected motion of the user's head, that a user is about to be struck by a vehicle (e.g., car, bicycle, etc.), that the user is proximate a wall or other object, or any number of other activities.
Next, the wireless earpieces generate one or more alerts or communications in response to the radar measurements (step 606). The alerts or communications may also be communicated based on a user request, user preferences, or so forth. The alerts or communications may represent alerts, messages, tactile feedback, sounds, or audio communicated by the wireless earpieces or text messages, in-app communications, streaming content, packets, or other alerts or communications sent from the wireless earpieces to any number of other users/devices (directly or indirectly).
Next, the wireless earpieces communicate the one or more alerts or communications (step 608). The one or more alerts or communications may be sent directly (e.g., utilizing Bluetooth, Wi-Fi, NFMI, etc.), or through any number of networks or devices (e.g., Wi-Fi, LAN, cellular networks, cloud networks, mesh networks, etc.). In one embodiment, a receiving device may perform a specified activity based on the alert or communication. For example, a vehicle may prepare for a collision by tightening the seatbelts, braking, swerving, flashing lights, preparing or firing airbags, or so forth. In another example, the alert may indicate to one or more designated parties that the user may have been injured (e.g., concussion, trauma, etc.). The wireless earpieces may also warn the user “watch out on your left” or any number of other applicable audio warnings. In one embodiment, the communications may include a command or instruction to a connected device. For example, a helmet worn by the user may cinch up or inflate one or more pouches/bags in response to determining a collision may be imminent.
In one embodiment, the wireless earpieces may perform Doppler measurements of blood flow, displacement of vessel walls, and/or movement/volume of the residual component of the external auditory canal. For example, the Doppler-frequency of the blood flow velocity may be determined for detectable flow velocities. In one embodiment, the radar measurements may be utilized to identify the ear, head, or body of the user. For example, a unique radar signature (e.g., structure of the inner/outer ear, cheek, jaw bone, bone structure of the head, body musculature, etc.) may be associated with each user. The unique radar signature may be saved as part of a user profile, settings, or other biometric information and may be utilized to subsequently identify or authenticate the user for future usage of the wireless earpieces. For example, user authentication may be utilized to determine the features, functions, contacts, and other data that is available to the user based on the authentication and authorizations that may be performed utilizing the radar signature determined during step 702. In another embodiment, the radar measurements may also determine where the wireless earpieces are being worn, stored, or so forth. For example, the radar measurements may determine placement in an ear of the user, placed on a desk/counter/surface, charging in a smart charger, or so forth.
Next, the wireless earpieces measure detected changes in the radar measurements (step 704). The changes may be utilized to determine changes in the biometrics of the user, environmental conditions, and so forth. The changes may measure changes in amplitude, phase, detected phase angle, and other aspects of the received or reflected signal. The biometrics of the user may include pulse rate, heart rate variability, blood flow velocity, blood pressure, pulse oximetry (SpO2), respiration rate, Stridor level, cerebral edema, and other central nervous system (CNS) acute phenomena). For example, changes in blood flow may change the radar signature of the user being measured as compared to baseline parameters.
Next, the wireless earpieces perform analysis of the measurements and changes to generate results (step 706). The analysis of the measurements may include an amplitude of the received signals. For example, the wireless earpieces may utilize backscatter from the active signals. The wireless earpieces may measure amplitude, phase (e.g., offset, difference, angle, etc.), and other information of the received signals. The results may indicate the location of the user, proximity to users, buildings, or other objects, location of a paired or associated device (e.g., position, orientation, distances, etc.), motion relative to the user, buildings, or other objects, and so forth. For example, distances, relative motion, and orientation between paired devices, such as the wireless earpieces and a cell phone or a wireless headset and a tablet may be determined.
The analysis may include combining multiple sensor measurements. For example, sensor measurements from accelerometers, thermistors, optical sensors, photoreceptors, magnetometers, gyroscopes, pressure sensors, environmental nanoparticle sensors, and any number of sensors.
Next, the wireless earpieces communicate the results to one or more users (step 708). The results may be played, displayed, or otherwise communicated to the user of the wireless earpieces or one or more designated users, devices, systems, equipment, interfaces, websites, servers, or so forth. The user preferences or other information may specify how, when, and where the results are communicated.
A system, method, and wireless earpieces are provided for performing radar measurements. The radar sensors of the wireless earpieces may be internally or externally directed. Any number of pulse, pattern, active, passive, or continuous signal radar systems may be utilized. The radar sensors may be utilized to measure a physiological parameter from which information, such as hear rate based on the movement (displacement) of blood within the veins, arteries, tissues, or skin of the user's ear. The radar sensors may also measure the movement or displacement of the vessel walls, movement of the residual component of the external auditory canal, and so forth. The radar measurements may be effective even in the presence of sweat, water, dirt, dust, or during strenuous physical activities.
In one embodiment, the wireless earpieces may utilize radar measurements to determine their relative location to other devices (e.g., paired, associated, communicating electronic devices, detectable, etc.), the user, structures, objects, or so forth.
The features, steps, and components of the illustrative embodiments may be combined in any number of ways and are not limited specifically to those described. In particular, the illustrative embodiments contemplate numerous variations in the smart devices and communications described.
