Examples described herein relate to hearing devices, and include particularly canal hearing devices including wireless capabilities for actuation, control, or communications with an external appliance, including a medical device.
The ear canal 10, as illustrated in
Placement of a canal hearing device inside the ear can be challenging due to difficulty in access and manipulation of a miniature canal device, particularly when intended for placement inside the ear canal 10 for achieving various advantages including reduction of the acoustic occlusion effect, improved energy efficiency, reduced distortion, reduced receiver (speaker) vibrations, and improved high frequency response. A well-known advantage of ear canal 10 placement is also aesthetics as many hearing-impaired individuals refuse to wear visible hearing devices such as in-the-ear (ITE) or behind-the-ear (BTE) types.
A canal hearing device can be inserted entirely or partially inside the ear canal. In the context of this application, any hearing device inserted inside the ear canal, whether partially or completely, may be referred to as a canal hearing device. This includes what is known in the hearing aid industry as Completely-In-The-Canal (CIC) and In-The-Canal (ITC) types.
Switches placed on canal hearing devices are generally difficult to reach or activate. These switches may be cumbersome if not impossible for those with dexterity limitations. Switches for hearing devices are generally implemented for larger hearing devices such as BTEs and ITEs for access and manual manipulation to deal with dexterity limitations.
Current hearing devices include wireless capabilities to receive transmit a variety of signals. The signals may include telephony audio, consumer electronics audio, and/or programming signals. In some examples, hearing devices connect to a computing device such as a mobile device or a personal computer to receive the wireless signals. In some examples, wireless hearing devices connect with an intermediary device that receives wireless signals from a source device external to the hearing device and re-trans s or relays the signal to the hearing device in proximity to the intermediary device.
A canal hearing device may include a medial portion, a lateral portion, and wireless electronics. The medial portion may include a speaker. The medial portion may be configured for placement in an ear canal of an ear. The lateral portion may include a wireless antenna and one or more switches. At least one of the switches may be arranged on the lateral portion such that the switch is located in a concha cavity of the ear when the medial portion is placed inside the ear canal. At least one of the switches may be provided behind a tragus of the ear for manual activation by the tragus.
The canal hearing device may include wireless electronics communicatively coupled to the wireless antenna. The wireless electronics may be configured to transmit a wireless signal to an external appliance in proximity to the canal hearing device and/or a remote medical alert service. The wireless signal may be transmitted responsive to manual activation of the switch. In some examples, the external appliance may be a medical device. The canal hearing device may wirelessly control one or more functions of the external appliance in response to activation of at least one of the switches. The canal hearing device may produce an audio signal from the speaker when the canal hearing device is in proximity to the external appliance.
The above and still further objectives, features, aspects and attendant advantages of the present invention will become apparent from the following detailed description of certain preferred and alternate embodiments and method of manufacture and use thereof constituting the best mode presently contemplated of practicing the invention, when taken in conjunction with the accompanying drawings, in which:
Certain details are set forth below to provide a sufficient understanding of embodiments of the invention. However, it will he appreciated by one skilled in the art that sonic embodiments may not include all details described. In some instances, well-known structures, hearing aid components, circuits, and controls, have not been shown in order to avoid unnecessarily obscuring the described embodiments of the invention.
The present disclosure describes examples of systems and methods of wireless remote control of appliances external to the ear using a canal hearing device. One embodiment of the present disclosure involves a canal hearing devices including a switch for manual activation. In some examples, the canal hearing device may control an appliance external to the ear upon manual activation of the switch.
The lateral portion 102 may be positioned lateral to (away from the eardrum 15) and may include a battery portion 101 and a handle portion 104 (also referred to herein as “handle”) for placement in the concha cavity 5 behind the tragus 3. The lateral portion 102 may include one or more switches, a wireless antenna, and a battery cell. In some examples, the battery cell may he rechargeable. The lateral portion 102 may be removable, partially disengageable, or integral with the medial portion 106. The lateral portion 102 may further include a sound port and sound channel for receiving incoming sound, for example as described in U.S. Pat. No. 8,467,556, titled CANAL HEARING DEVICE WITH DISPOSABLE BATTERY MODULE (“'556 patent”), and U.S. Pat. No. 8,855,345, titled BATTERY MODULE FOR PERPENDICULAR DOCKING INTO A CANAL HEARING DEVICE (“'345 patent”), which are both incorporated herein by reference in their entirety for any purpose. In some examples, the compliant canal retainer 108 may he removably coupled to the medial end 106 and configured to retain the canal hearing device 100 in the ear. In some examples, the compliant canal retainer 108 may be removable and provided in an assortment of sizes to fit in a variety of ear canal shapes and sizes. In some examples, the compliant canal retainer 108 is disposable.
The lateral portion 102 may include one or more switches that may be activated in response to a manual force. In some examples, the one or more switches may be provided on the handle 104 of the canal hearing device 100. In some examples, the one or more switches may be provided on a housing of the lateral portion 102, such as on the side of the housing (
In some examples, the one or more switches may be implemented as a rocker switch 502 on a handle 500 of the canal hearing device 100, as shown in
The lateral portion 102 may include a wireless antenna 118. In some examples, the wireless antenna 118 may be a chip antenna, for example a ceramic chip antenna. The wireless antenna 118 may be communicatively coupled to wireless electronics 116 of the canal hearing device 100. The wireless electronics 116 may be provided in any of the medial portion 106 or the lateral portion 102. The wireless electronics 116 may include functionality to transmit and receive wireless signals. The wireless electronics 116 may utilize standardized protocols, such as Bluetooth, near-field magnetic induction, Wi-Fi, Zigbee or any other known wireless protocol. In some examples, the wireless electronics 116 include low power and low energy functionalities compatible with miniature button cell or coin cell batteries commonly used for hearing aids and miniature electronic devices. Bluetooth, including Low Energy (LE) versions, is particularly suited.
The wireless electronics 116 may communicate wirelessly with an appliance 800 (
The wireless electronics 116 of the canal hearing device 100 may communicatively couple with wireless electronics 808 of the appliance 800 to transmit and receive wireless signals 802. The wireless signals 802 may include commands, audio, and/or any other type of data. In some examples, the wireless electronics 116 of the canal hearing device 100 may transmit a wireless signal 802 in response to the manual activation of any of the one or more switches of the canal hearing device 100. The wireless signal 802 may include a signal configured to control the appliance 800. The wireless signal 802 may be received by the appliance 800, and a processor 804 of the appliance 800 may be in communication with the appliance controller 806 and an appliance operating system 814 to control the appliance 800. The appliance 800 may include memory 810 for storing appliance configuration data and the appliance operating system 814. The appliance configuration data may include control parameters for control and/or actuation of the appliance 800 in response to receiving the wireless signal 802. Thus, the user 1 may apply a manual force to the tragus 3 and/or directly to any of the switches 110-114 of the canal hearing device 100 to control the appliance 800. The actuation and/or control of the appliance 800 may include adjustment of the appliance 800 as discussed above, such as manipulating a light or lock. Thus, it may be advantageous to use a canal hearing device 100 as a remote control to mitigate the need for an external remote device such as a remote control or a mobile phone.
In some examples, the canal hearing device 100 may automatically detect the presence of an external appliance 800 in proximity In other words, the canal hearing device 100 may be configured to automatically detect the external appliance 800 when the external appliance 800 is within a wireless detection range. The appliance 800 may be in sufficient proximity to the canal hearing device 100 such that a wireless signal may be received from and/or transmitted to the canal hearing device 100 from the appliance 800. It will be appreciated that the distance defining proximity depends on the wireless capability of the canal hearing device 100 and the wireless protocol. For example, a proximity range may be 2-10 meters for low energy Bluetooth. In some examples, a proximity range may be extended using a mesh network. In some examples, the wireless electronics 116 may periodically scan for the presence of an appliance 800, or respond to a scan from the appliance 800. In some examples, the wireless electronics 116 may perform a scan in response to a manual activation of a switch 110-114. The canal hearing device 100 may pair to the proximately positioned appliance 800 upon detection of the appliance 800. The canal hearing device 100 may access appliance control parameters 130 associated with the detected appliance 800 and configuration data 132 from memory 128 of the canal hearing device 100. The appliance control parameters 130 determine the control associated with the appliance 800 and/or switch mapping for the appliance 800 (e.g., which switch performs which command). The configuration data 132 may include personal user settings, personal fitting parameters, appliance preferences, etc. For example, the configuration data 132 may include appliance preferences ranking appliances based on usage or user preference, automatic control settings of an appliance 800 (e.g., automatic door unlock), and/or alert settings for an appliance 800.
In some examples, the canal hearing device 100 may be configured to produce an audible signal from the speaker 124 when the canal hearing device 100 is worn in the ear and in proximity to the appliance 800. In some examples, the canal hearing device 100 includes a speaker 124 in the medial portion 106 to transmit audible signals 120 into the ear canal 10. The audible signal 120 may be representative of audio signals streamed from an appliance 800 or internally generated by the canal hearing device 100, for example by playing back an audio segment related to the appliance 800 in proximity In some examples, audio data 134 associated with the audio segment may be stored in memory 128 of the canal hearing device 100. The audio data 134 stored in memory 128 may be accessed and the audio segment may be played back using the sound processor 126 within the canal hearing device 100 in response to the detection. The audio segment may be played back in response to the activation or control of the appliance 800, which may be caused by activation of a switch of the canal hearing device. The production of the audible signal 120 may be terminated by manually activating a switch of the canal hearing device 100. The terms audio segment and audible segment may be used interchangeably herein.
In some examples, the canal hearing device 100 may automatically detect the presence of the appliance 800. In response to detection of the appliance 800, the canal hearing device 100 may transmit an appropriate audible signal 120 (e.g., an audible segment) to a user 1 wearing the canal hearing device 100. The audible signal 120 may be produced through the speaker 124. The audible signal 120 may alert the user 1 to the presence of the appliance 800 in proximity and allow the user 1 to wirelessly control the appliance 800 detected in proximity by the canal hearing device 100. In some examples, control of the appliance 800 is automatic. Thus, the one or more switches of the canal hearing device 100 may not be required to control the appliance 800. The canal hearing device 100 may detect the presence of an appliance 800 in proximity to the canal hearing device 100 and control the appliance 800 based on appliance control parameters 130 and configuration data 132 (collectively referred to herein as “configuration parameters”) stored within memory 128 of the canal hearing device 100. For example, the canal hearing device 100 may detect the presence of a lock and in response to detecting the lock, the canal hearing device 100 may wirelessly transmit a secure open-door command signal to unlock a door for entry. This may be advantageous to provide a hands-free home entry for a user 1 wearing the canal hearing device 100. In other examples, the open-door command is transmitted upon activation of a hearing device switch positioned in the concha cavity 5 behind the tragus 3, according to the examples of the present disclosure.
In some examples, upon detection of the appliance 800 in proximity, the canal hearing device 100 may retrieve appliance status data of the appliance 800, for example whether a door is locked or unlocked, or whether the appliance is on or off. The canal hearing device 100 may transmit a wireless control signal to the appliance based on the appliance status data. For example, the canal hearing device 100 may transmit a wireless control signal to unlock the door only when the appliance status data indicates that the door is locked and will not perform any action if the door is already unlocked. In some examples, the canal hearing device 100 may detect whether the appliance 100 is getting closer or further away when in proximity range, for example when the user 1 is approaching a door or moving away from the door, and send a wireless control signal accordingly. For example, the canal hearing device 100 may unlock a door when the user 1 is approaching and lock a door when the user 1 is moving away.
In some examples, a binaural set of hearing devices may be configured differently and independently for the control of the same or multiple appliances. For example, a first canal hearing device of a binaural set may be configured for controlling a light and a second canal hearing device may be configured for controlling a television. One switch of the first canal hearing device may be configured for actuation of appliances (e.g., On/Off for a TV or lighting), while the switches of the second canal hearing device may be configured to change the settings of the appliances, for example changing the volume, channel, dimming, or other settings.
In some examples, the canal hearing device 100 may include telephony functionalities via wireless connectivity to a telephone. A first switch of the canal hearing device 100 may be manually activated to answer an incoming call. The canal hearing device 100 may transmit a telephone audio signal to the ear canal 10 of the user using the speaker 124 of the canal hearing device 100 in response to the activation of the switch to answer the phone call. A second or the same switch of the canal hearing device 100 may be manually activated to adjust the volume of the telephone audio signal in the ear upon taking the incoming call.
The canal hearing device 100 may store audio data 134 that may be played back using the sound processor 126 and speaker 124 of the canal hearing device 100 to alert the user to an incoming call or message. The alert may be a stored audio segment or may be provided to the canal hearing device 100 wirelessly during the incoming call, for example to include the name of the caller in the alert. The audio data 134 may include voice messages or voice memos. The audio data 134 may include text messages converted to audio messages, such as from e-mail, SMS, social media posts, and/or other text-based messages. The computing device 900, for example a smartphone, may provide the canal hearing device 100 with voice messages, voice memos, and/or text messages converted to audio messages. The canal hearing device 100 may include an interface for presenting stored audio data 134 to the user 1, such as by listing the stored messages and allowing the user 1 to scroll and select the one(s) they wish to play back using the switches 110-114.
In some examples, the appliance 800 may be a medical device. The canal hearing device 100 may detect the presence of the medical device. Upon detection of the medical device or by a command from the medical device, the canal hearing device 100 may transmit an audio signal (also referred to herein as audible signal) to the ear canal 10 of the user 1. The canal hearing device 100 may receive alerts related to a medical or health event from the medical device. The canal hearing device 100 may present the alert to the user 1 by transmitting an audio signal to the ear canal 10 of the user 1. In response to a manual activation of a switch of the canal hearing device 100, the canal hearing device 100 may transmit a wireless signal to the medical device for acknowledgment, control or verification. For example, the canal hearing device 100 may communicate wirelessly with an electronic medicine dispenser bottle (referred to herein as “e-dispenser”) housing one or more medications (pills, for example) and provide an audible signal as a reminder for the user 1 to take any of the medications upon a wireless request from the c-dispenser. The user 1 may disable or terminate the repeating audio messages by activating a switch on the canal hearing device 100 which may also trigger a wireless confirmation signal to the e-dispenser.
The e-dispenser, through its processor, may perform a verification of taking the medication, for example by ensuring that the user 1 actually accessed a repository (e.g., opened a bottle cap) of the e-dispenser during an appropriate time frame. The verification may be initiated by transmitting a wireless confirmation signal to the canal hearing device 100. In sonic examples, the e-dispenser may include sensors to detect if the medication has been removed from the repository. If verification is negative, the e-dispenser may continue to request the canal hearing device 100 to generate an audible reminder signal through the speaker 124 of the canal hearing device 100. The audible reminder signal may be continuous or periodic. If the verification is positive, the canal hearing device 100 may terminate the audible reminder.
The computing device 900 may wirelessly transmit control signals 902 to set appliance control parameters 130 of the canal hearing device. The control parameter 130 may define a set of remote control functions and settings of a medical device (e.g., medical device 850). The canal hearing device 100 may use the appliance control parameters 130 to transmit appropriate wireless signals 802 to the medical device to perform the remote control functions. In this manner, the user 1 may control a medical device without direct physical contact with the medical device nor the use of an external device. This may be particularly advantageous for performing functions of a relatively inaccessible medical device, for example an implanted device or a medical device that is hard to reach.
In some examples, the canal hearing device 100 may detect the presence of the medical device. Upon detection of the medical device, the canal hearing device 100 may transmit an audio signal 120 to the ear canal 10 of the user 1. The canal hearing device 100 may wirelessly receive alerts related to medical or health events from the medical device. The canal hearing device 100 may present the alerts to the user 1 by transmitting an audio signal 120 to the ear canal 10 of the user 1. In response to a manual activation of a switch of the canal hearing device 100 may trigger the canal hearing device 100 to transmit a wireless signal 802 to the medical device for acknowledgment, control or verification.
In some examples, the canal hearing device 100 may be configured for verification of a medical request, such as consuming a medication from an electronic dispensing bottle 850 (
The medical device may perform a verification in response to the manual activation of the switch of the canal hearing device 100. It may be advantageous to perthrm the verification to ensure that the user 1 has performed a task related to the medical request. In some examples, manual activation of the switch may terminate the transmission of the alert. Continuing with the example of electronic dispensing bottle 850, the canal hearing device 100 may request a verification signal to the electronic dispensing bottle. If the verification fails, the canal hearing device 100 may resume transmission of the alert until the user 1 properly complies with taking the medication.
In some examples, the canal hearing device 100 may incorporate physiologic sensors within. The physiologic sensors may include, but are not limited to, any of electrodes, a temperature sensor, oxygen sensor, accelerometer, gyroscope, and a glucose meter. It will be understood that a variety of physiologic and motion sensors may be included in the canal hearing device 100. Incorporating the physiological sensors within the canal hearing device 100 may be advantageous because the ear canal 10 is tethered to the human body during activity, for example walking or exercise, and the physiology of the ear canal 10 includes capillaries suited to measure certain physiological parameters such as heart rate. Additionally, blood to the ear canal 10 is usually supplied by the branches of the common carotid artery, which contributes directly to the perfusion of the brain. Thus, placing the physiological sensors in the canal hearing device 100 may allow for more reliable physiological measurements because the ear canal 10 may be less affected by movement, temperature changes, and other sources of variability that are experienced by the periphery of the body. Further, a processor within the canal hearing device 100 may execute software to mitigate noise due to motion artifacts (e.g., walking or chewing).
In some examples, electrodes may be provided on the housing of the canal hearing device 100 to detect the heart rate of the user 1. In some examples, a theiniometer may be provided in the canal hearing device 100 to detect the temperature of the user 1. In some examples, a glucose meter may be provided in the canal hearing device 100 to detect a blood glucose level of the user 1. In some examples, optical sensors may be provided on an external surface of the canal hearing device 100 to provide and receive reflected light to provide infoiniation on blood flow through the nearby tissue. Any of the physiological sensors may be provided on a medial or lateral portion 102 of the canal hearing device 100. Data received from the physiological sensors (also referred to as sensor data) may be analyzed to calculate and/or determine health parameters, such as calories burned.
The canal hearing device 100, through the processor within, may automatically detect the presence of a medical appliance, or a health condition, to transmit an appropriate audio signal 120, which may be in the form of a message through the speaker within. Thus, an appropriate wireless remote control signal corresponding to the specific medical appliance detected within proximity may be transmitted. In some examples, the actuation or control of the medical appliance is automatic, thereby not requiring an activation of a switch. For example, when sensors within the canal hearing device 100 detect a medical condition such as low temperature or high heart rate, the canal hearing device 100 may transmit an appropriate wireless signal 802 to address the medical condition. The appropriate wireless signal 802 may be determined using appliance control parameters 130 of the canal hearing device 100. The appliance control parameters 130 may include audible alerts to transmit based on the sensor readings. In some examples, the canal hearing device 100 may measure low blood sugar using the physiological sensors (e.g., a glucose meter) and send a remote control signal to an insulin pump to deliver insulin to the bloodstream of the user. The amount of insulin delivered by the insulin pump may be based on the level of blood sugar measured by the physiological sensors.
In some examples, the canal hearing device 100 is configured as an alert initiator during a medical condition or an emergency, such as a fall or a. heart attack. In some examples, a fall may be detected using an accelerometer and/or a gyroscope within the canal hearing device 100. In some examples, a heart attack may be detected using a heart rate sensor within the canal hearing device 100. Appliance control parameters 130 of the canal hearing device 130 may be used to determine that a medical condition or an emergency has occurred. The appliance control parameters 130 may include one or more patterns of various medical conditions and/or emergencies, such as abnormal heart rate or gyroscope readings associated with a fall or inactivity. The canal hearing device 100 may determine that the medical emergency has occurred when the sensor readings match one or more of the patterns. The canal hearing device 100 may communicate with a remote medical alert service when the user 1 presses a switch on the lateral portion of the canal hearing device 100. In some examples, the switch may be pressed for a prolonged period, such as 2 or more seconds, indicating a medical emergency. A prolonged press may be advantageous to ensure that the switch is not being accidently pressed, or to differentiate from other remote control functions not associated with a medical emergency.
In some examples, the canal hearing device 100 may transmit an audio signal 120 to the ear canal 10 in response to detecting a medical condition or a medical emergency. The medical condition or medical emergency may be detected using one or more sensors of the canal hearing device 100. For example, an accelerometer and/or a gyroscope of the canal hearing device 100 may be used to determine that the user 1 has fallen. The canal hearing device 100 may transmit an audio signal 120 to the ear canal 10 in response to detecting the fall. The audio signal 120 may be a periodic alert. The user response may be a momentary activation of the switch or a prolonged activation of the switch.
By placing the canal hearing device 100 in the ear canal 10 such that the canal hearing device 100 extends laterally to the concha cavity 5 and behind the tragus 3, the canal hearing device 100 may be inconspicuously and securely worn. This may allow for minimal impact on the lifestyle of the user 1, for example, without substantially interfering with vigorous activity such as running, hunting, sports and exercising in general. Additionally, the switches of the canal hearing device 100 are accessible to the user 1 to actuate wireless signals to a variety of appliances, thereby allowing for control of other devices used and encountered in daily life.
In some examples, the canal hearing device 100 is water-proof allowing for showering and swimming while being worn. The inconspicuous wear of the canal hearing device 100 behind the tragus allows for discrete and private communications without altering others for any personal use. Existing Bluetooth-enabled hearing devices considerably extend laterally from the ear, compromising secure and inconspicuous wear.
In step 1002, a manual force may be applied to a tragus to activate a switch positioned on a lateral portion of a canal hearing device. The lateral portion may include wireless electronics for communicatively coupling the canal hearing device to an external appliance. The canal hearing device may include a medial portion including a speaker. The switch may be arranged on the lateral portion such that the switch is positioned in a concha cavity of an ear when the canal hearing device is inserted in the ear. In step 1004, a wireless control signal may be transmitted by the canal hearing device in response to the activation of the switch when the external appliance is in proximity to the canal hearing device. The wireless control signal may be configured to control a function of the external appliance. In some examples, the external appliance may include a medical device.
Although examples of the invention have been described herein, it will be recognized by those skilled in the art to which the invention pertains from a consideration of the foregoing description of presently preferred and alternate embodiments and methods of fabrication and use thereof, and that variations and modifications of this exemplary embodiment and method may be made without departing from the true spirit and scope of the invention. Thus, the above-described embodiments of the invention should not be viewed as exhaustive or as limiting the invention to the precise configurations or techniques disclosed. Rather, it is intended that the invention may be limited only by the appended claims and the rules and principles of applicable law.
