DETAILED DESCRIPTION OF THE DISCLOSURE

The illustrative embodiments provide a system, method, wireless earpieces, and personal area network for managing power utilization of wireless earpieces. The wireless earpieces may utilize a low power mode to preserve battery life when changes in light conditions or motion are not detected. As a result, the power capacity of the wireless earpieces may be reserved for utilization by a user rather than wasted when not in use or even visible to the user. Preserving the battery life or power available is particularly important because of the reduced size of the wireless earpieces and the limited space available for the battery. In addition, the wireless earpieces may become particularly important to a user for business, exercise, or personal activities and, therefore, merit preserving power whenever possible to optimize the user's experience.

The wireless earpieces may be utilized to play music or audio, track user biometrics, perform communications (e.g., two-way, alerts, etc.), provide feedback/input, and any number of tasks. The wireless earpieces may execute software or sets of instructions stored in an on-board memory utilizing a processor to accomplish numerous tasks. The wireless earpieces may also be utilized to control, communicate, manage, or interact with a number of other computing, communications, or wearable devices, such as smart phones, laptops, personal computers, tablets, vehicles, smart glasses, helmets, smart glass, watches or wrist bands, chest straps, implants, displays, clothing, or so forth. In one embodiment, the wireless earpieces may be part of a personal area network. A personal area network is a network for data transmissions among devices, such as personal computing, communications, camera, vehicles, entertainment, and medical devices. The personal area network may utilize any number of wired, wireless, or hybrid configurations and may be stationary or dynamic. For example, the personal area network may utilize wireless network protocols or standards, such as INSTEON, IrDA, Wireless USB, near field magnetic induction (NFMI), Bluetooth, Z-Wave, ZigBee, Wi-Fi, ANT+ or other applicable radio frequency signals. In one embodiment, the personal area network may move with the user.

Any number of conditions, factors, and so forth may be utilized to determine whether the wireless earpieces should enter a low power, sleep, hibernation, or other reduced power mode, status, or configuration. In one embodiment, 1) changes in light conditions detected by at least two sensors may be utilized, and 2) detection of a movement event by the wireless earpieces and/or other interconnected devices may be utilized to determine whether a low power mode should be activated.

In one embodiment, ambient light may be detected by a first set of infrared detectors housed in or near an exterior or outer surface of the wireless earpieces. The infrared sensors may be utilized to detect finger touches or gestures controlling the features and functionality when the wireless earpieces are being worn. A second set of optical sensors may be positioned against the ear of the user when worn. The second set of optical sensors may include light emitting diodes (LEDs) configured to perform measurements within the ear of the user to measure biometrics, such as pulse rate, blood pressure, temperature, respiration rate, blood oxygenation, blood chemical levels, and other discernable information.

The utilization of the two sets of spatially separated optical sensors provides for enhanced detection and analysis. Light and motion changes made may be sensed by the first set of infrared detectors and the second set of optical sensors and compared to determine whether actual light or motion changes are detected. As a result, false positives associated with perceived changes in light or motion may be reduced or eliminated. The battery power of the wireless earpieces is conserved for user utilization of the wireless earpieces. For example, the charge of the batteries (e.g., batteries of the wireless earpieces, packaging batteries, etc.) may be conserved on store shelves when the wireless earpieces are still incorporated in original packaging.

The wireless earpieces may include any number of sensors for reading user biometrics, such as pulse rate, blood pressure, blood oxygenation, temperature, calories expended, blood or sweat chemical content, voice and audio output, impact levels, and orientation (e.g., body, head, etc.). The sensors may also determine the user's location, position, velocity, impact levels, and so forth. The sensors 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 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 and converted into commands possibly sent to one or more external devices, such as a tablet computer, smart phone, or so forth.

The wireless earpieces may perform sensor measurements for the user to read any number of user biometrics. The user biometrics may be analyzed including measuring deviations or changes of the sensor measurements over time, identifying trends of the sensor measurements, and comparing the sensor measurements to control data for the user.

FIG. 1 is a pictorial representation of a communications environment 100 in accordance with an illustrative embodiment. The wireless earpieces 102 may be configured to communicate with each other and with one or more wireless devices, such as a wireless device 104 or a personal computer 118. The wireless earpieces 102 may be worn by a user 106 and are shown as worn and separately from their positioning within the ears of the user 106 for purposes of visualization. A block diagram of the wireless earpieces 102 if further shown in FIG. 2 to further illustrate components and operation of the wireless earpieces 102.

In one embodiment, the wireless earpieces 102 includes a frame 108 shaped to fit substantially within the ears of the user 106. The frame 108 is a support structure partially enclosing and housing the electronic components of the wireless earpieces 102. The frame 108 may be composed of a single structure or multiple interconnected structures. 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 detecting and measuring 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 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. This information may be utilized to determine whether the wireless earpieces should be in a low power mode for conserving battery capacity or a full power mode for actual usage or preparing for utilization by the user 106. In one embodiment, the infrared sensors 109 may also include detectors for measuring light from any number of wavelengths (e.g., visible light within a room or other environment).

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. 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 possibly utilizing 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 pulse, blood oxygenation, temperature, voice characteristics, skin conduction, glucose levels, impacts, activity level, position, location, orientation, as well as any number of internal or external user biometrics. 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, or even micro-delivery systems for receiving, measuring, and delivering information and signals. Small electrical charges 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 possibly emitting and measuring 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. The optical sensors may be utilized to preserve battery power of the wireless earpieces 102 when not being actively utilized by the user 102 or being retrieved to be worn. In one embodiment, the sensors 112 may be utilized in addition to the infrared sensors 109 to determine the power mode or status utilized by the wireless earpieces 102. The sensors 112 may similarly detect changes in motion, light, or user contact possibly utilized to select the associated power mode for preserving battery life. The sensors 112 may also be utilized to sense or provide a small electrical current which may be useful for alerting the user, stimulating blood flow, alleviating nausea, or so forth.

In some applications, temporary adhesives or securing mechanisms (e.g., clamps, straps, lanyards, extenders, etc.) may be utilized to ensure the wireless earpieces 102 remain in the ears of the user 106 even during the most rigorous and physical activities or if they do fall out they 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. 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 be utilized with any number of automatic assistants, such as Sin, Cortana, 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, 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. 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 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 during normal usage. 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 app (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 possibly activating the full power mode or possibly keeping 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.

The user 106 or another party may also utilize the wireless device 104 to associate user information and conditions with the power state. For example, an application executed by the wireless device 104 may be utilized to specify the conditions “waking up” the wireless earpieces 102 including all or a portion of the functionality possibly corresponding to a full power mode. In addition, the power states and enabled functions (e.g., sensors, transceivers, vibration alerts, speakers, lights, etc.) may be selectively activated during each power state. In another embodiment, the wireless earpieces 102 may be adjusted or trained over time to become even more accurate in adjusting between power modes. The wireless earpieces 102 may utilize historical information to generate default values, baselines, thresholds, policies, or settings for determining when and how the power modes are implemented. As a result, the wireless earpieces 102 may effectively manage the power capacity based on automatic detection of events (e.g., light, motion, etc.) and user specified settings.

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, 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 possibly affecting how the wireless earpieces 102 manage power utilization. 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 possibly 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 when detected by the wireless earpieces 102 are utilized to put the wireless earpieces 102 in a sleep mode in anticipation of taking the wireless earpieces 102 out of the ears of the user 106.

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. A personal area network is a network for data transmissions among devices, such as personal computing, communications, camera, vehicles, entertainment, and medical devices. The personal area network may utilize any number of wired, wireless, or hybrid configurations and may be stationary or dynamic. For example, the personal area network may utilize wireless network protocols or standards, such as INSTEON, IrDA, Wireless USB, Bluetooth, Z-Wave, ZigBee, Wi-Fi, ANT+ or other applicable radio frequency signals. In one embodiment, the personal area network may move with the user 106.

In other embodiments, the communications environment 100 may include any number of devices, components, or so forth possibly communicating with each other directly or indirectly through a wireless (or wired) connection, signal, or link. The communications environment 100 may include one or more networks and network components and devices represented by the network 120, such as routers, servers, signal extenders, intelligent network devices, computing devices, or so forth. In one embodiment, the network 120 of the communications environment 100 represents a personal area network as previously disclosed. The power settings and management herein described may also be utilized for any number of devices in the communications environment 100 with commands or communications being sent by the wireless earpieces 102 or wireless device 104 to control the power settings for the devices.

Communications within the communications environment 100 may occur through the network 120 or a Wi-Fi network or may occur directly between devices, such as the wireless earpieces 102 and the wireless device 104. 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. 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 the power settings, mode, or status in use or being implemented. For example, one or more alerts may indicate when power state changes are pending, 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 change the power state. The corresponding alert may also be communicated to the user 106, the wireless device 104, and the personal computer 118.

In other embodiments, the wireless earpieces 102 may also vibrate, flash, play a tone or other sound, or give other indications of the power status of the wireless earpieces 102. The wireless earpieces 102 may also communicate an alert to the wireless device 104 showing up as a notification, message, or other indicator indicating the changed status.

The wireless earpieces 102 as well as the wireless device 104 may include logic for automatically implementing power management functions in response to motion, light, or various other conditions and factors of the communications environment 100.

The wireless device 104 may represent any number of wireless or wired electronic communications or computing devices, such as smart phones, laptops, desktop computers, control systems, tablets, displays, gaming devices, music players, personal digital assistants, vehicle systems, or so forth. The wireless device 104 may communicate utilizing any number of wireless connections, standards, or protocols (e.g., near field communications, NFMI, Bluetooth, Wi-Fi, wireless Ethernet, etc.). For example, the wireless device 104 may be a touch screen cellular phone communicating with the wireless earpieces 102 utilizing Bluetooth communications. The wireless device 104 may implement and utilize any number of operating systems, kernels, instructions, or applications making use of the available sensor data sent from the wireless earpieces 102. For example, the wireless device 104 may represent any number of android, iOS, Windows, open platforms, or other systems and devices. Similarly, the wireless device 104 or the wireless earpieces 102 may execute any number of applications utilizing the user input, proximity data, biometric data, and other feedback from the wireless earpieces 102 to initiate, authorize, or process power management processes and perform the associated tasks.

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.

FIG. 2 is a block diagram of a wireless earpiece system 200 in accordance with an illustrative embodiment. In one embodiment, the wireless earpiece system 200 may include wireless earpieces 202 (described collectively rather than individually). In one embodiment, the wireless earpiece system 200 may enhance communications and functionality of the wireless earpieces 202.

As shown, the wireless earpieces 202 may be wirelessly linked to a computing device 204. For example, the computing device 204 may represent a wireless tablet computer. The computing device 204 may also represent a gaming device, cell phone, vehicle system (e.g., GPS, speedometer, pedometer, entertainment system, etc.), gaming device, smart watch, laptop, smart glass, or other electronic devices. User input and commands may be received from either the wireless earpieces 202 or the computing device 204 for implementation on either of the devices of the wireless earpiece system 200 (or other externally connected devices). As previously noted, the wireless earpieces 202 may be referred to or described herein as a pair (wireless earpieces) or singularly (wireless earpiece). The description may also refer to components and functionality of each of the wireless earpieces 202 collectively or individually.

In some embodiments, the computing device 204 may act as a logging tool for receiving information, data, or measurements made by the wireless earpieces 202. For example, the computing device 204 may download data from the wireless earpieces 202 in real-time. As a result, the computing device 204 may be utilized to store, display, and synchronize data for the wireless earpieces 202. For example, the computing device 204 may display pulse, proximity, location, oxygenation, distance, calories burned, and so forth as measured by the wireless earpieces 202. The computing device 204 may be configured to receive and display alerts indicating conditions to enter a low power mode have been met. For example, the wireless earpieces 202 may utilize factors, such as changes in motion or light, distance threshold between the wireless earpieces 202 and/or computing device 204, signal activity, or other automatically determined or user specified measurements, factors, conditions, or parameters, the wireless earpieces 202 may enter the low power mode and generate a message to the computing device 204 indicating the wireless earpieces 202 have entered the low power mode.

The computing device 204 may also include several optical sensors, touch sensors, and other measurement devices providing feedback or measurements the wireless earpieces 202 may utilize to determine an appropriate power mode, settings, or enabled functionality to be utilized. The wireless earpieces 202 and the computing device 204 may have any number of electrical configurations, shapes, and colors and may include various circuitry, connections, and other components.

In one embodiment, the wireless earpieces 202 may include a battery 208, a logic engine 210, a memory 212, a user interface 214, a physical interface 215, a transceiver 216, and sensors 217. The computing device 204 may have any number of configurations and include components and features similar to the wireless earpieces 202 as are known in the art.

The battery 208 is a power storage device configured to power the wireless earpieces 202. In other embodiments, the battery 208 may represent a fuel cell, thermal electric generator, piezo electric charger, solar charger, ultra-capacitor, or other existing or developing power storage technologies. The illustrative embodiments preserve the capacity of the battery 208 by reducing unnecessary utilization of the wireless earpieces 202 in a full-power mode when there is little or no benefit to the user (e.g., the wireless earpieces 202 are sitting on a table or temporarily lost). The battery 208 or power of the wireless earpieces are preserved for when being worn or operated by the user. As a result, user satisfaction with the wireless earpieces 202 is improved and the user may be able to set the wireless earpieces 202 aside at any moment knowing battery life is automatically preserved by the logic engine 210 and functionality of the wireless earpieces 202.

The logic engine 210 is the logic controlling the operation and functionality of the wireless earpieces 202. The logic engine 210 may include circuitry, chips, and other digital logic. The logic engine 210 may also include programs, scripts, and instructions possibly implemented to operate the logic engine 210. The logic engine 210 may represent hardware, software, firmware, or any combination thereof. In one embodiment, the logic engine 210 may include one or more processors. The logic engine 210 may also represent an application specific integrated circuit (ASIC) or field programmable gate array (FPGA).

The logic engine 210 may utilize motion or light measurements from two or more of the sensors 217 to determine whether the wireless earpieces 202 are in use or being stored. The logic engine 210 may control a power mode utilized by the wireless earpieces 202 in response to any number of measurements from the sensors 217, the transceiver 216, the user interface 214, or the physical interface 215. The logic engine 210 may also shut down all or portions of the components of the wireless earpieces 202 to preserve the life of the battery 208 based on the applicable condition or state of the wireless earpieces (e.g., worn and in-use, setting on a desk and unused, in a smart charger, etc.).

In addition, the logic engine 210 may utilize the signal strength sensed by the transceiver 216 to determine the proximity of the wireless earpieces 202 to each other as well as the computing device 204. The logic engine 210 may also determine whether the wireless earpieces 202 are actively performing any user-requested functions indicating the wireless earpieces 202 are active. For example, the logic engine may determine whether music is being played, communications being received, processed, or sent, noise-cancellation is being performed and so forth. Utilizing the proximity information and signal activity, the logic engine 210 may provide instructions to enter the low power mode. In one embodiment, the logic engine 210 may turn off or reduce power to most of the components of the wireless earpieces. For example, the logic engine 210 may completely power down the wireless earpieces 202 requiring the user to turn the wireless earpieces 202 back on in response to detecting no changes in light or motion for more than 2 hours. In another example, the logic engine 210 may turn off power to most of the components except for the sensors 217 and logic engine 210 possibly periodically determining whether motion, light, or user feedback is received. If user feedback or communications are detected or received, the logic engine 210 may wake up or power up the wireless earpieces 202 from the low power mode to a regular or full-power mode. The wireless earpieces 202 may be configured to work together or completely independently based on the needs of the user.

The logic engine 210 may also process user input to determine commands implemented by the wireless earpieces 202 or sent to the wireless earpieces 204 through the transceiver 216. Specific actions may be associated with power modes. For example, the logic engine 210 may implement a macro allowing the user to associate common conditions with specific modes of operation, such as normal operations (full power mode) for when the wireless earpieces 202 are positioned within the ears of the user, low power mode when the wireless earpieces 1) are not being worn by the user, and 2) do not detect changes in light and motion, recharge mode when the wireless earpieces 202 and are close together (e.g., closer than when worn in the ears of the user) within the smart case, low power mode if the wireless earpieces 202 are not being worn and close together, low power mode for each of the wireless earpieces 202 if separated by a significant distance and not being worn, and any number of other conditions. The logic engine 210 may utilize two sensor arrays (e.g., infrared, LED, etc.) to detect light and motion.

In one embodiment, a processor included in the logic engine 210 is circuitry or logic enabled to control execution of a set of instructions. The processor may be one or more microprocessors, digital signal processors, application-specific integrated circuits (ASIC), central processing units, or other devices suitable for controlling an electronic device including one or more hardware and software elements, executing software, instructions, programs, and applications, converting and processing signals and information, and performing other related tasks.

The memory 212 is a hardware element, device, or recording media configured to store data or instructions for subsequent retrieval or access later. The memory 212 may represent static or dynamic memory. The memory 212 may include a hard disk, random access memory, cache, removable media drive, mass storage, or configuration suitable as storage for data, instructions, and information. In one embodiment, the memory 212 and the logic engine 210 may be integrated. The memory may use any type of volatile or non-volatile storage techniques and mediums. The memory 212 may store information related to the status of a user, wireless earpieces 202, computing device 204, and other peripherals, such as a wireless device, smart glasses, a smart watch, a smart case for the wireless earpieces 202, a wearable device, and so forth.

In one embodiment, the user may provide feedback by tapping the user interface 214 once, twice, three times, or any number of times. Similarly, a swiping motion may be utilized across or in front of the user interface 214 (e.g., the exterior surface of the wireless earpieces 202) to implement a predefined action. Swiping motions in any number of directions or gestures may be associated with specific activities, such as play music, pause, fast forward, rewind, activate a digital assistant (e.g., Siri, Cortana, smart assistant, etc.). The swiping motions may also be utilized to control actions and functionality of the computing device 204 or other external devices (e.g., smart television, camera array, smart watch, etc.).

In one embodiment, the sensors 217 may be integrated with the user interface 214 to detect or measure the user input. For example, infrared sensors positioned against an outer surface of the wireless earpieces 202 may detect touches, gestures, or other input as part of a touch or gesture sensitive portion of the user interface 214. The outer or exterior surface of the user interface 214 may correspond to a portion of the wireless earpieces 202 accessible to the user when the wireless earpieces are worn within the ears of the user.

In addition, the sensors 217 may include pulse oximeters, accelerometers, gyroscopes, magnetometers, inertial sensors, photo detectors, miniature cameras, and other similar instruments for detecting user biometrics, environmental conditions, location, utilization, orientation, motion, and so forth.

The sensors 217 may provide measurements or data possibly utilized to select, activate, or enter a low power mode. Likewise, the sensors 217 may be utilized to awake, activate, initiated, or otherwise enter a full power or normal mode for the wireless earpieces 202. For example, the optical biosensors within the sensors 217 may determine whether the wireless earpieces 202 are being worn or whether there are changes in motion or light indicative of the wireless earpieces 202 being picked up for usage. Similarly, a lack of changes in motion or light as well as no detectable contact with the user may be utilized to enter or maintain a low power mode.

As previously noted, the wireless earpieces 302 may include any number of internal or external sensors. The sensors 301 may make independent measurements or combined measurements utilizing the sensory functionality of each of the sensors to measure, confirm, or verify sensor measurements.

In one embodiment, the sensors 301 may include optical sensors 304 and contact sensors 306. The optical sensors 304 may generate an optical signal communicated to the ear (or other body part) of the user and reflected. The reflected optical signal may be analyzed to determine blood pressure, pulse rate, pulse oximetry, vibrations, blood chemistry, and other information about the user. The optical sensors 304 may include any number of sources for outputting various wavelengths of electromagnetic radiation and visible light. Thus, the wireless earpieces 302 may utilize spectroscopy as it is known in the art and developing to determine any number of user biometrics.

The optical sensors 304 may also be configured to detect ambient light proximate the wireless earpieces 302. For example, the optical sensors 304 may detect light and light changes in an environment of the wireless earpieces, such as in a room where the wireless earpieces 302 are located. The optical sensors 304 may be configured to detect any number of wavelengths including visible light possibly relevant to light changes, approaching users or devices, and so forth.

In another embodiment, the contact sensors 306 may be utilized to determine the wireless earpieces 302 are positioned within the ears of the user. For example, conductivity of skin or tissue within the user's ear may be utilized to determine the wireless earpieces are being worn. In other embodiments, the contact sensors 306 may include pressure switches, toggles, or other mechanical detection components for determining the wireless earpieces 302 are being worn. The contact sensors 306 may measure or provide additional data points and analysis possibly indicating the biometric information of the user. The contact sensors 306 may also be utilized to apply electrical, vibrational, motion, or other input, impulses, or signals to the skin of the user.

The wireless earpieces 302 may also include infrared sensors 308. The infrared sensors 308 may be utilized to detect touch, contact, gestures, or other user input. The infrared sensors 308 may detect infrared wavelengths and signals. In another embodiment, the infrared sensors 308 may detect visible light or other wavelengths as well. The infrared sensors 308 may be configured to detect light or motion or changes in light or motion. Readings from the infrared sensors 308 and the optical sensors 304 may be configured to detect light or motion. The readings may be compared to verify or otherwise confirm light or motion. As a result, logic decisions regarding utilizing specified power modes or conserving power utilization may be made based on the sensors 301 as well as other internal or external sensors of the wireless earpieces 302.

In another embodiment, the wireless earpieces 302 may include chemical sensors (not shown) performing chemical analysis of the user's skin, excretions, blood, or any number of internal or external tissues or samples. For example, the chemical sensors may determine whether the wireless earpieces 302 are being worn by the user. In one embodiment, the chemical sensors are non-invasive and may only perform chemical measurements and analysis based on the externally measured and detected factors. In other embodiments, one or more probes, vacuums, capillary action components, needles, or other micro-sampling components may be utilized. Minute amounts of blood or fluid may be analyzed to perform chemical analysis possibly reported to the user and others. The sensors 301 may include parts or components possibly periodically replaced or repaired to ensure accurate measurements. In one embodiment, the infrared sensors 308 may be a first sensor array and the optical sensors 304 may be a second sensor array.

FIG. 4 is a flowchart of a process for determining a condition of a user utilizing wireless earpieces in accordance with an illustrative embodiment. The process of FIG. 4 may be implemented by one or more wireless earpieces, such as the wireless earpieces 102 of FIG. 1. In another embodiment, one or more steps or portions of the process of FIG. 4 may be implemented by a wireless device, computing device, wearable devices, or any number of other devices communicating directly or through a network with the wireless earpieces.

Although not specifically shown, the wireless earpieces may be linked with communications devices. The wireless earpieces may be linked with the communications device, such as a smart phone, utilizing any number of communications, standards, or protocols. For example, the wireless earpieces may be linked with a cell phone by a Bluetooth connection. The process may require the devices be paired utilizing an identifier, such as a passcode, password, serial number, voice identifier, radio frequency, or so forth. The wireless earpieces may be linked with the communications device and any number of other devices directly or through one or more networks, such as a personal area network. The wireless earpieces may be linked so sensor readings from the wireless device(s) may be sent to the wireless earpieces to supplement the sensor measurements and readings performed by the wireless earpieces. In addition, any number of alerts, messages, or indicators may be sent between the two devices to present information to the user.

The process of FIG. 4 may begin by performing sensor measurements utilizing a first sensor array (step 402). In one embodiment, the sensor measurements may correspond to an infrared sensor array or first optical sensors. The infrared sensor array may measure user inputs, such as a touch by a finger or gesture performed in front of the infrared sensor. The infrared sensor array may be positioned so it is external to the body of the user when the wireless earpieces are worn by the user.

Next, the wireless earpieces perform sensor measurements utilizing a second sensor array. In one embodiment, the sensor measurements may correspond to a second set of optical sensors of the wireless earpieces. The optical sensors may detect specified wavelengths, visible light, or any number of wavelengths. The optical sensor array may be positioned, so the sensor array is positioned proximate or against skin or tissue of the ear of the user (e.g., near or against the epithelium of the external auditory canal or auricular region of the user's ears). During steps 402 and 404, sensor measurements may include performing any number of biometric measurements. For example, metabolic, chemical, pigmentation, or other biometric readings may be taken. As noted, the optical sensors may utilize a specific wavelength(s) and the corresponding reflections to measure biometrics as well as environmental conditions. The measurements may be performed utilizing a predefined sampling rate (e.g., 1/s, 1/100 ms, 1/min, etc.). Other biometric sensors, such as mechanical (e.g., vibration, elasticity, tension, etc.) or electrical sensors, may perform additional measurements or confirm or verify the measurements. The measurements may also be triggered in response to specific detected events, such as change in the orientation or position (e.g., change from vertical to horizontal position), changes in movement or velocity, high forces (e.g., impacts, jolts, etc.), or detected events from other sensors worn by the user. The sensor measurements of steps 402 and 404 are configured to conserve battery life. For example, only a portion of the sensor arrays may be utilized. Similarly, the sensor arrays may only be powered on at specified intervals to preserve power utilized by the wireless earpieces. In one embodiment, one or more portions of the wireless earpieces may include solar cells for charging the internal battery utilizing ambient light. Internal piezo electric generators may also generate power based on the motion of the wireless earpieces.

Next, the wireless earpieces analyze the sensor measurements (step 406). The sensor measurements may be processed or otherwise evaluated by the wireless earpieces. For example, one or more processors of the wireless earpieces may process the incoming data measurements from the first and second sensor arrays. During step 406 the sensor measurements may be compared against each other. The sensor measurements may be compared to determine whether a detected event (e.g., change in light or motion) is verifiable or confirmed by more than one sensor of one or both wireless earpieces. As a result, the wireless earpieces may be configured to avoid false positive events thereby preserving battery life for actual utilization by the user. Additional, optical, chemical, mechanical, and/or electrical sensors of the wireless earpieces or a connected wireless device may also be utilized. The sensor measurements are processed for subsequent analysis, determinations, or decisions, implemented by the wireless earpieces.

Next, the wireless earpieces determine whether a change event is detected (step 408). The change event may be utilized to change a power state of the wireless earpieces. The change event may represent changes in light and/or motion detected by the first sensor array, second sensor array, or other sensors of the wireless earpieces or a connected wireless device. For example, changes in light and/or motion may indicate the wireless earpieces are being picked up and the wireless earpieces should activate all systems to be ready for user utilization. In another embodiment, the change event may be one or more conditions, factors, or parameters established automatically (e.g., default or factory settings) or by the user based on user input or feedback. Other sensor measurements, such as audio input, impacts, or so forth may also be utilized to detect the change event.

In response to determining the change event is detected, the wireless earpieces determine whether the change event is confirmed (step 410). The change event may be verified or confirmed during step 410 based on sensor readings from first sensor array, second sensor array or other sensors as previously noted. The change event may be detected by a single sensor array (e.g., simultaneously, concurrently, sequentially, etc.) or by multiple sensor arrays before being confirmed by secondary or other systems of the wireless earpieces or communicating wireless devices.

In response to confirming the change event during step 410, the wireless earpieces activate a full power mode (step 412). During step 412, all or a portion of the sub-system of the wireless earpieces may be powered on. For example, the full power mode may be initiated to prepare one or both of the wireless earpieces for utilization. In some embodiments, the user may specify conditions, parameters, or factors possibly utilized for the wireless earpieces to enter the full power mode. In another embodiment, only a portion of the wireless earpiece sub-systems may be activated until additional conditions have been met. For example, the transceiver may be activated for communications with the wireless earpieces until contact sensors detect the wireless earpieces are being worn by the user for at least three seconds.

In response to determining a change event is not detected during step 408 or the change event is not confirmed during step 410, the wireless earpieces activate a low power mode (step 414). In one embodiment, the wireless earpieces may have already been in a low power mode and thus the wireless earpieces remain in the low power mode without changes in status or the operating mode being utilized by the wireless earpieces. During the low power mode, the wireless earpieces may be operating to preserve the battery life of the wireless earpieces. For example, only a portion of the sensors and/or logic may be operating or periodically activated to perform the measurements of steps 402 and 404. In other embodiments, limited sub-systems of the wireless earpieces may be operating during the low power mode. The low power mode may also represent a sleep, hibernation, or other reduced power function of the wireless earpieces. Next, the wireless earpieces return to perform sensor measurements utilizing the first sensor array (step 402). The process of FIG. 4 may be performed in a loop to ensure the battery life of the wireless earpieces is preserved and maintained for utilization when worn in the ears of the user.
