Description

Technical Field

[0001] The present invention generally relates to regulating the operation of non-standardized wireless protocols associated with medical devices. Background Art

[0002] Medical devices have provided a wide range of therapeutic benefits to recipients over the last several decades. Medical devices may include internal or implantable components / devices, external or wearable components / devices, or combinations thereof (e.g., devices having external components that communicate with implantable components). Medical devices, such as traditional hearing aids, partially or fully implantable hearing prostheses (e.g., bone conduction devices, mechanical stimulators, cochlear implants, etc.), pacemakers, defibrillators, functional electrical stimulation devices, and other medical devices, have been successful for many years in performing life-saving and / or lifestyle improvement functions and / or recipient monitoring.

[0003] Over the years, the types of medical devices and the range of functions performed by them have increased. For example, many medical devices, sometimes referred to as "implantable medical devices," now typically include one or more instruments, devices, sensors, processors, controllers, or other functional mechanical or electrical components that are permanently or temporarily implanted in a recipient's body. These functional devices are typically used to diagnose, prevent, monitor, treat, or manage disease / injury or its symptoms, or to study, replace, or modify anatomical structures or physiological processes. Many of these functional devices utilize power and / or data received from an external device that is part of or operates in conjunction with the implantable component. Summary of the invention

[0004] In one aspect, a method is provided. The method includes: transmitting first wireless data from an external portion of a hearing device to an implantable portion of the hearing device via a first wireless link operating according to a first wireless protocol; receiving second wireless data from an external device via a second wireless link operating according to a second wireless protocol; and adjusting operations associated with the first wireless protocol based on operations of the second wireless protocol.

[0005] In another aspect, one or more non-transitory computer-readable storage media are provided. The one or more non-transitory computer-readable storage media include instructions that, when executed by a processor, cause the processor to: transmit a first data packet from an external portion of a medical device to an implantable portion of the medical device via a first wireless link; receive a second data packet from an external device via a second wireless link; and adjust one or more operating parameters of the first wireless link based on one or more operating parameters associated with the second wireless link.

[0006] In another aspect, an apparatus is provided. The apparatus includes: at least one wireless interface; a memory; and at least one processor, the at least one processor being configured to: transmit first wireless data according to a first wireless protocol via the at least one wireless interface; receive second wireless data sent according to a second wireless protocol via the at least one wireless interface; and adjust one or more parameters of the first wireless protocol data based on one or more parameters of the second wireless protocol.

[0020] The apparatus may include at least one wireless interface that operates to transmit and / or receive first wireless data (first data packet) over a first wireless link and simultaneously transmit and / or receive second wireless data (second data packet) over a second wireless link. Different wireless protocols (such as Low Energy (BLE), other standardized protocols and / or non-standardized / proprietary protocols can share the same spectrum. Therefore, when multiple wireless links are transmitting data / packets simultaneously, there may be limitations on, for example, the transmission time (airtime) and air bandwidth. These limitations are typically caused by the presence of multiple audio channels and the need for retransmissions. Retransmission of data / packets may be required to overcome packet loss due to radio signal fading and interference from adjacent transceivers operating in the same frequency band (i.e., 2.4 GHz) (which may cause packet collisions). If packets have been damaged or lost, they can be retransmitted. In this arrangement, conflicts may occur (e.g., due to the same spectrum) that reduce the quality of data (e.g., audio) on the first wireless link and / or the second wireless link.

[0021] Presented herein are techniques for adjusting one or more parameters or operations associated with a first wireless link operating according to a first wireless protocol (e.g., a non-standardized / proprietary wireless protocol) based on one or more parameters or operations associated with a second wireless link operating according to a second wireless protocol (e.g., a standardized protocol). By adjusting parameters and / or operations associated with the first wireless link (e.g., a link operating according to a non-standardized / proprietary protocol), simultaneous operation of the first wireless link and the second wireless link can be optimized. For example, data (e.g., audio) quality of both links can be improved while minimizing or avoiding packet drops.

[0022] In certain embodiments, the techniques described herein facilitate an intra-system radio link with a short duration (such as an incoming call from a smartphone delivered to a behind-the-ear (BTE) / off-the-ear (OTE) device or an implantable device via Bluetooth Low Energy (BLE) audio), which may temporarily degrade the audio quality of another wireless link (e.g., a same-side non-standardized radio link from an external portion of a hearing device to an implantable portion at 2.4 GHz). In particular, the embodiments described herein provide for dynamic and automatic changes to one or more operations or parameters of a first wireless link based on one or more operations or parameters of a second wireless link. For example, the system may dynamically adjust the audio compression ratio of a codec to change the bit rate of data sent on a first wireless link when a second wireless link from an external device is being used, dynamically adjust the number of retransmissions associated with the first wireless link, etc. to provide an optimal audio experience for a minimum air bandwidth (transmission time).

[0023] For ease of description only, the technology presented herein is mainly described with reference to a specific implantable medical device system, i.e., a cochlear implant system. However, it should be understood that the technology presented herein can also be partially or completely implemented by other types of implantable medical devices. For example, the technology presented herein can be implemented by other auditory prosthesis systems including one or more other types of auditory prostheses (e.g., middle ear auditory prostheses, bone conduction devices, direct acoustic stimulators, electroacoustic prostheses, auditory brain stimulators, combinations or variations thereof, etc.). The technology presented herein can also be implemented by proprietary tinnitus treatment devices and tinnitus treatment device systems. In other embodiments, the technology presented herein can also be implemented by vestibular devices (e.g., vestibular implants), visual devices (i.e., bionic eyes), sensors, pacemakers, drug delivery systems, defibrillators, functional electrical stimulation devices, catheters, epileptic seizure devices (e.g., devices for monitoring and / or treating epileptic events), sleep apnea devices, electroporation devices, etc., or used in combination with them.

[0024] Figures 1A-1D An exemplary cochlear implant system 102 is shown with which aspects of the technology presented herein may be implemented. The cochlear implant system 102 includes an external component 104 / implantable component 112. Figures 1A-1D In the example of a cochlear implant, the implantable component is sometimes referred to as a "cochlear implant." Figure 1A The cochlear implant 112 is shown implanted in the recipient's head 154, while Figure 1B is a schematic diagram of the outer member 104 worn on the head 154 of the recipient. Figure 1C is another schematic diagram of a cochlear implant system 102, and Figure 1D Additional details of cochlear implant system 102 are shown. For ease of description, the Figures 1A-1D .

[0025] Cochlear implant system 102 includes an external component 104 configured to be attached directly or indirectly to the body of a recipient, and an implantable component 112 configured to be implanted in the body of the recipient. Figures 1A-1D In the example of FIG. 1 , external component 104 includes a sound processing unit 106 , while cochlear implant 112 includes an implantable coil 114 , an implant body 134 , and an elongated stimulation assembly 116 configured to be implanted in the cochlea of ​​a recipient.

[0026] exist Figures 1A-1D In the example of the present invention, the sound processing unit 106 is an off-the-ear (OTE) sound processing unit, sometimes referred to herein as an OTE component, which is configured to send data and power to the implantable component 112. Generally speaking, the OTE sound processing unit is a component having a generally cylindrical housing 111 and configured to be magnetically coupled to the head of the recipient (e.g., including an integrated external magnet 150 configured to be magnetically coupled to an implantable magnet 152 in the implantable component 112). The OTE sound processing unit 106 also includes an integrated external (head component) coil 108 configured to be inductively coupled to the implantable coil 114.

[0027] It should be understood that the OTE sound processing unit 106 is merely illustrative of an external device that can operate with the implantable component 112. For example, in alternative examples, the external component can include a behind-the-ear (BTE) sound processing unit or a micro-BTE sound processing unit and a separate external component. Generally speaking, the BTE sound processing unit includes a housing that is shaped to be worn on the recipient's outer ear and connected to a separate external coil assembly via a cable, wherein the external coil assembly is configured to be magnetically coupled and inductively coupled to the implantable coil 114. It should also be understood that alternative external components can be located in the recipient's ear canal, worn on the body, etc.

[0028] As described above, cochlear implant system 102 includes sound processing unit 106 and cochlear implant 112. However, as further described below, cochlear implant 112 can operate independently of sound processing unit 106 for at least a period of time to stimulate a recipient. For example, cochlear implant 112 can operate in a first general mode (sometimes referred to as an "external listening mode"), in which sound processing unit 106 captures sound signals, which are then used as a basis for delivering stimulation signals to the recipient. Cochlear implant 112 can also operate in a second general mode (sometimes referred to as an "invisible hearing" mode), in which sound processing unit 106 cannot provide sound signals to cochlear implant 112 (e.g., sound processing unit 106 is not present, sound processing unit 106 is powered off, sound processing unit 106 is malfunctioning, etc.). Therefore, in the invisible hearing mode, cochlear implant 112 captures the sound signals itself via an implantable sound sensor, and then uses these sound signals as a basis for delivering stimulation signals to the recipient. Further details regarding the operation of cochlear implant 112 in the external listening mode are provided below, followed by details regarding the operation of cochlear implant 112 in the invisible listening mode. It should be understood that the reference to the external listening mode and the invisible listening mode is merely illustrative, and cochlear implant 112 may also operate in alternative modes.

[0029] exist Figure 1A and 1C , a cochlear implant system 102 is shown with an external device 110 configured to implement various aspects of the presented technology. The external device 110 is a computing device, such as a computer (e.g., a laptop, a desktop computer, a tablet), a mobile phone, a remote control unit, etc. As further described below, the external device 110 includes a telephone enhancement module, as further described below, which is configured to implement various aspects of the auditory rehabilitation technology presented herein for independent telephone use. The external device 110 and the cochlear implant system 102 (e.g., an OTE sound processing unit 106 or a cochlear implant 112) communicate wirelessly via a two-way communication link 126. The two-way communication link 126 may include, for example, short-range communication, such as a Bluetooth link, a Bluetooth low energy (BLE) link, a non-standardized link, etc.

[0030] Return to Figures 1A-1DIn the example of the OTE sound processing unit 106, one or more input devices are configured to receive input signals (e.g., sound or data signals). The one or more input devices include one or more sound input devices 118 (e.g., one or more external microphones, audio input ports, telecoils, etc.), one or more auxiliary input devices 128 (e.g., audio ports, such as direct audio input (DAI), data ports, such as universal serial bus (USB) ports, cable ports, etc.), and wireless transmitter / receiver (transceiver) 120 (e.g., for communicating with external devices 110). However, it should be understood that the one or more input devices may include additional types of input devices and / or fewer input devices (e.g., the wireless short-range radio transceiver 120 and / or one or more auxiliary input devices 128 may be omitted).

[0031] The OTE sound processing unit 106 also includes an external coil 108, a charging coil 130, a tightly coupled transmitter / receiver (RF transceiver) 122 (sometimes referred to as a radio frequency (RF) transceiver 122), at least one rechargeable battery 132, and an external sound processing module 124. The external sound processing module 124 may include, for example, one or more processors and a memory device (memory) including sound processing logic. The memory device may include any one or more of the following: non-volatile memory (NVM), ferroelectric random access memory (FRAM), read-only memory (ROM), random access memory (RAM), magnetic disk storage media devices, optical storage media devices, flash memory devices, electrical, optical or other physical / tangible memory storage devices. The one or more processors are, for example, microprocessors or microcontrollers that execute instructions of the sound processing logic stored in the memory device.

[0032] The implantable component 112 includes an implant body (main module) 134, a lead region 136, and an intracochlear stimulation assembly 116, all configured to be implanted beneath the skin / tissue (tissue) 115 of a recipient. The implant body 134 typically includes a hermetically sealed housing 138 in which an RF interface circuit system 140 and a stimulator unit 142 are disposed. The implant body 134 also includes an internal / implantable coil 114, which is typically external to the housing 138 but is accessible via a hermetic feedthrough ( Figure 1D ) is connected to the RF interface circuit system 140.

[0033] As described, the stimulation assembly 116 is configured to be at least partially implanted in the cochlea of ​​the recipient. The stimulation assembly 116 includes a plurality of longitudinally spaced intracochlear electrical stimulation contacts (electrodes) 144 that collectively form a contact or electrode array 146 for delivering electrical stimulation (electrical current) to the cochlea of ​​the recipient.

[0034] The stimulation assembly 116 extends through an opening in the recipient's cochlea (e.g., a cochlear fenestration, a round window, etc.) and has a lead region 136 and an airtight feedthrough ( Figure 1D 144 is connected to the proximal end of the stimulator unit 142 (not shown). The lead region 136 includes a plurality of conductors (wires) that electrically couple the electrode 144 to the stimulator unit 142. The implantable component 112 also includes an electrode outside the cochlea, sometimes referred to as an extracochlear electrode (ECE) 139.

[0035] As described, the cochlear implant system 102 includes an external coil 108 and an implantable coil 114. An external magnet 152 is fixed relative to the external coil 108, and the implantable magnet 152 is fixed relative to the implantable coil 114. The magnets fixed relative to the external coil 108 and the implantable coil 114 facilitate operational alignment of the external coil 108 with the implantable coil 114. This operational alignment of the coils enables the external component 104 to transmit data and power to the implantable component 112 via a tightly coupled wireless link 148 formed between the external coil 108 and the implantable coil 114. In some examples, the tightly coupled wireless link 148 is a radio frequency (RF) link. However, various other types of energy transfer (e.g., infrared (IR), electromagnetic, capacitive, and inductive transfer) may be used to transfer power and / or data from the external component to the implantable component, and thus, Figure 1D Only one exemplary arrangement is shown. According to the techniques described herein, operation of wireless link 148 may be adjusted when external component 104 or implantable component 112 receives data (eg, voice data or an audio stream) from an external device via another wireless link.

[0036] As described above, the sound processing unit 106 includes an external sound processing module 124. The external sound processing module 124 is configured to convert an input signal received (received at one or more of the input devices) into an output signal for stimulating the first ear of the recipient (i.e., the external sound processing module 124 is configured to perform sound processing on the input signal received at the sound processing unit 106). In other words, the one or more processors in the external sound processing module 124 are configured to execute the sound processing logic in the memory to convert the received input signal into an output signal representing electrical stimulation for delivery to the recipient.

[0037] As stated, Figure 1D An embodiment is shown in which an external sound processing module 124 in the sound processing unit 106 generates an output signal. In an alternative embodiment, the sound processing unit 106 can send less processed information (e.g., audio data) to the implantable component 112, and the sound processing operations (e.g., conversion of sound to output signals) can be performed by a processor within the implantable component 112.

[0038] Return to Figure 1D In a specific example of the invention, the output signal is provided to the RF transceiver 122, which transmits the output signal (e.g., in an encoded manner) transcutaneously to the implantable component 112 via the external coil 108 and the implantable coil 114. That is, the output signal is received at the RF interface circuit system 140 via the implantable coil 114 and provided to the stimulator unit 142. The stimulator unit 142 is configured to generate an electrical stimulation signal (e.g., a current signal) for delivery to the cochlea of ​​the recipient using the output signal. In this way, the cochlear implant system 102 electrically stimulates the auditory nerve cells of the recipient, thereby bypassing the missing or defective hair cells that normally convert acoustic vibrations into neural activity in a manner that causes the recipient to perceive one or more components of the received sound signal.

[0039] As described in detail above, in the external listening mode, the cochlear implant 112 receives processed sound signals from the sound processing unit 106. However, in the invisible listening mode, the cochlear implant 112 is configured to capture and process the sound signals for electrical stimulation of the recipient's auditory nerve cells. Figure 1D As shown in , the cochlear implant 112 includes a plurality of implantable sound sensors 160 and an implantable sound processing module 158. Similar to the external sound processing module 124, the implantable sound processing module 158 may include, for example, one or more processors and a memory device (memory) including sound processing logic. The memory device may include any one or more of the following: non-volatile memory (NVM), ferroelectric random access memory (FRAM), read-only memory (ROM), random access memory (RAM), magnetic disk storage media devices, optical storage media devices, flash memory devices, electrical, optical or other physical / tangible memory storage devices. The one or more processors are, for example, microprocessors or microcontrollers that execute instructions of the sound processing logic stored in the memory device.

[0040] In the invisible hearing mode, the implantable sound sensor 160 is configured to detect / capture a signal (e.g., an acoustic sound signal, a vibration, etc.), which is provided to the implantable sound processing module 158. The implantable sound processing module 158 is configured to convert the received input signal (received at one or more implantable sound sensors 160) into an output signal for stimulating the first ear of the recipient (i.e., the processing module 158 is configured to perform a sound processing operation). In other words, the one or more processors in the implantable sound processing module 158 are configured to execute the sound processing logic in the memory to convert the received input signal into an output signal 156 that is provided to the stimulator unit 142. The stimulator unit 142 is configured to generate an electrical stimulation signal (e.g., an electric current signal) for delivery to the cochlea of ​​the recipient using the output signal 156, thereby bypassing the missing or defective hair cells that normally convert the acoustic vibrations into neural activity.

[0041] It should be appreciated that the above description of the so-called external listening mode and the so-called invisible listening mode is merely illustrative, and that cochlear implant system 102 may operate differently in different embodiments. For example, in an alternative embodiment of the external listening mode, cochlear implant 112 may use the signals captured by sound input device 118 and implantable sound sensor 160 to generate stimulation signals for delivery to the recipient.

[0042] Figure 2A and 2B An exemplary cochlear implant system 102 is shown with which aspects of the techniques presented herein may be implemented.

[0043] exist Figure 2A and 2B In the example shown, cochlear implant system 102 includes external component 104, cochlear implant 112, and an external device, such as user device 210. User device 210 may be, for example, a cellular phone, a tablet computer, an audio player, or a computer capable of communicating with the user via a communication link that may include, for example, short-range communication, such as Another device that forms a wireless connection with external component 104 and / or cochlear implant 112. Figure 2A and 2B In the example shown, user device 210 is a cellular telephone.

[0044] like Figure 2AAs shown in FIG. 1 , external component 104 has established a non-standardized / proprietary wireless link with cochlear implant 112. For example, external component 104 may transmit data to cochlear implant 112 using a transmission protocol having a relatively high bit rate. User device 210 may receive a phone call and may establish a wireless link with cochlear implant 112 to transmit audio data from the phone call. In this example, cochlear implant 112 has established a first link with external component 104 using a first wireless protocol and a second link with user device 210 using a second wireless protocol. In this example, packets transmitted on the relatively high bit rate link between external component 104 and cochlear implant 112 collide with packets on the incoming link between user device 210 and cochlear implant 112. When a large number of collisions occur, the quality of one or both links degrades.

[0045] exist Figure 2B In the example shown in , external component 104 has established a relatively high bit rate non-standardized wireless link with cochlear implant 112, and user device 210 has established a wireless link with external component 104 to transmit audio data in response to receiving a telephone call. In this example, external component 104 has established a first link with cochlear implant 112 using a first wireless protocol, and a second link with user device 210 using a second wireless protocol. Because both wireless protocols operate in the same frequency band with limited bandwidth, packets transmitted at a relatively high bit rate between external component 104 and cochlear implant 112 collide with packets transmitted from user device 210 to external component 104 on the incoming link. In this example, the collision may result in a degradation of the audio quality of one or both links.

[0046] In the above Figure 2A and 2B In the example described in , parameters and / or operation of a wireless link (e.g., a wireless protocol associated with a non-standardized link) between external component 104 and cochlear implant 112 can be adjusted to improve the audio quality of one or both links. As further described below, parameters and / or operation of a wireless protocol associated with a non-standardized link can be dynamically adjusted by adjusting the audio compression ratio of a codec and / or the number of retransmissions on the same-side non-standardized channel.

[0047] As follows about Figure 4As further described, the manner in which parameters are adjusted and / or operated may depend on many different factors. These factors may include, for example, the desired number of radio streams within the system, the current listening environment (e.g., theater, lecture, meeting, concert, restaurant, conference, etc.), indoor location versus outdoor location (noise), the current activity of the recipient of the hearing device (e.g., walking, running, playing sports, etc.), human speech in the transmitted data (e.g., male, female, child), the current mode of transportation, etc.

[0048] Figure 3A and 3B An exemplary cochlear implant system 102 is shown with which aspects of the techniques presented herein may be implemented.

[0049] Figure 3A Shows the above Figure 2A An example is described in which a non-standardized link has been established between external component 104 and cochlear implant 112 using a first transmission protocol, and a second link is established between user device 210 and cochlear implant 112 using a second transmission protocol (e.g., via a Bluetooth link). Figure 3A In the example shown, the codec of the non-standardized link is adjusted to reduce the bit rate so that data is transmitted between external component 104 and cochlear implant 112 using a lower / reduced bit rate (e.g., a bit rate lower than the bit rate normally used at the non-standardized link). When the bit rate is reduced, smaller and / or shorter packets are transmitted over the non-standardized link, which reduces the number of collisions between packets transmitted over the non-standardized link and packets transmitted over the link between user device 210 and cochlear implant 112. By reducing the bit rate, the throughput of the non-standardized link is reduced. However, due to fewer collisions, the two data streams are more reliable and there is packet loss when arriving at cochlear implant 112.

[0050] Figure 3B Shows the same as above Figure 2B In this example, external component 104 has established a relatively high bit rate link with cochlear implant 112, and user device 310 has established a second link with cochlear implant 112. In this example, user device 310 is streaming music to cochlear implant 112.

[0051] exist Figure 3BIn the example shown, in order to reduce collisions between the two links, the non-standardized link maintains a relatively high bit rate, but reduces the number of retransmissions. In other words, external component 104 reduces the retransmission rate of retransmitting packets to cochlear implant 112 (e.g., when a packet has been damaged or lost). By reducing the retransmission rate, the number of packets transmitted to cochlear implant 112 is reduced, which causes fewer collisions. Although reducing the retransmission rate may result in a temporarily less reliable non-standardized link, the two data streams arrive at cochlear implant 112 with fewer collisions.

[0052] Figure 4 A table 400 is shown showing examples of adjusting the operation / parameters of a non-standardized link in different scenarios. As discussed above, the operation / parameters of a non-standardized link may be adjusted in different ways to provide an optimal audio experience in different situations / conditions. The current audio environment as well as additional factors such as the type of audio associated with the second link (whether the external component 104 or the cochlear implant 112 is receiving audio on the second link), the number of other radio links in the vicinity of the recipient of the hearing device, etc. may affect the manner in which the operation / parameters of the non-standardized link are adjusted. The determination of the manner in which the operation / parameters are adjusted may be made at the external component 104, the cochlear implant 112, or another device (such as the external device 110).

[0053] In the example shown in table 400, the parameters / operations of the non-standardized link can be adjusted based on the user's current context even when the second link has not yet been established. As shown at table entry 410, when the user is outdoors talking to someone, the non-standardized link can maintain a relatively high bit rate, but the retransmission rate can be slightly reduced to allow for some retransmissions. As shown at 420, when the user is outdoors using a phone to stream music to external component 104, the bit rate of the non-standardized link can be reduced to "medium" and the retransmission rate can also be reduced to allow for some retransmissions.

[0054] In the example shown in table item 430, when the user is listening to music at a concert, the non-standardized link can have a relatively high bit rate with a large number of retransmissions to provide the highest quality and most reliable audio experience. In the example shown in table item 440, when the user is indoors answering a phone call, the user can focus on the phone call received via the second link, so that the parameters of the non-standardized link can be adjusted to provide a low bit rate without retransmissions. In this way, the audio quality of the phone call can be maximized. In the example shown in table item 450, when the user is in a library, streaming music to cochlear implant 112 (e.g., a lot of interference from Wi-Fi and Bluetooth connections of other devices), the non-standardized link can have a medium bit rate with a large number of retransmissions.

[0055] The entries shown in table 400 are exemplary, and these parameters may be adjusted in different or additional ways. Also, although only five examples are given in table 400, the operation / parameters of the non-standardized link may be adjusted in different other ways in different scenarios.

[0056] Figures 5A-5E An exemplary schematic diagram showing the transmission efficiency of different transmission modes of non-standardized links is shown. Figure 4 As described, the operation of a non-standardized link may switch between different modes based on different scenarios or other factors. Figures 5A-5E Data packets and conflicts between packets are shown. In some scenarios, only some data packets and / or conflicts are marked for brevity.

[0057] Figure 5A shows the transmission efficiency of a low bit rate non-standardized link, Figure 5B The transmission efficiency of a higher bit rate non-standardized link is shown. Figure 5A The receiver antenna (Rx) of the low bit rate non-standardized link shown in FIG. 1 receives seven (7) packets 510 - 1 to 510 - 7 over a first link within a certain period of time, Figure 5B The receiver of the higher bit rate non-standardized link shown in receives 13 packets over the first link during the time period. Figure 5A and 5B In the figure, only the first packet (510-1) and the last packet ( Figure 5A 510-7, Figure 5B 510-13). The higher bit rate non-standardized link receives packets at a greater rate than the lower bit rate non-standardized link.

[0058] Figure 5C The transmission efficiency of a low bit rate non-standardized link with retransmissions is shown. Figure 5C As shown in , the receiver receives packets 510-1 to 510-7, and retransmits packets 520-1 to 520-6. For example, the receiver receives packet 510-1, and retransmits packet 520-1. As another example, Rx receives packet 510-4, and retransmits packet 520-4. Packet 510-1 and retransmitted packet 520-1 may include the same data or payload (and in the same manner, packet 510-4 and retransmitted packet 520-4 may include the same data or payload). Retransmitted packets 520-1 to 520-6 may be transmitted, for example, when packets 510-1 to 510-6 are lost or damaged.

[0059] Figure 5DThe transmission efficiency of a relatively high bit rate non-standardized link using a first wireless protocol is shown when there is an incoming call transmitted over a second link to an external component 104 or a cochlear implant 112 using a second wireless protocol (e.g., using Bluetooth). Figure 5D In the example shown, the receiver receives packets 510-1 to 510-13 via the non-standardized link. In addition, the transmitter antenna (Tx) transmits additional packets 530-1 to 530-10 via the second link. Because the non-standardized link has a relatively high bit rate, packets 510-1 to 510-13 are transmitted / received at a high rate, which causes conflicts with packets transmitted / received on the second link.

[0060] like Figure 5D As shown in , the receiver receives packet 530-1 via the second link, but there is a collision 540-1 when packet 530-2 is transmitted via the second link. When packet 510-4 is received via the non-standardized link, and packet 530-3 is received via the second link, another collision 540-2 occurs. When packet 510-7 is received via the non-standardized link, a collision 540-3 occurs. When packets transmitted via the non-standardized link and the second link collide, additional collisions 540-4 to 540-6 occur. Figure 5D As shown in , when the non-standardized link has a relatively high bit rate, resulting in packet loss, multiple collisions occur when receiving a telephone call via the second link. This may result in low quality of audio received via the non-standardized link and / or the second link.

[0061] Figure 5E The transmission efficiency of a low bit rate non-standardized link using a first wireless protocol is shown when there is an incoming call transmitted over a second link to an external component 104 or a cochlear implant 112 using a second wireless protocol (e.g., using Bluetooth). Figure 5E As shown in FIG. 5 , packets 510-1 to 510-7 are transmitted via a non-standardized link. In addition, packets 530-1 to 530-9 are transmitted via a second link. Because the non-standardized link has a low bit rate and is not as fast as the reference link, Figure 5D The higher bit rate example depicted transmits fewer packets over the non-standardized link in a certain period of time, so three (3) collisions 540-1 through 540-3 occur (rather than six (6) collisions when the non-standardized link has a higher bit rate).

[0062] Fig. 5F The transmission efficiency of a low bit rate non-standardized link using a first wireless protocol is shown when there is an incoming call transmitted over a second link to an external component 104 or a cochlear implant 112 using a second wireless protocol (e.g., via Bluetooth) and when packets are retransmitted over the non-standardized link. Fig. 5FAs shown in FIG. 1 , packets 510-1 to 510-7 and retransmitted packets 520-1 to 520-6 are transmitted on a non-standardized link, and packets 530-1 to 530-10 are transmitted on a second link, which results in six (6) collisions 540-1 to 540-6. In this example, despite the large number of collisions, all audio data is still received on the non-standardized link because of the retransmissions. Therefore, when the packets are retransmitted, the user experiences excellent audio quality on the non-standardized link.

[0063] Figure 6 6 is a flow chart of a method 600 for adjusting operations associated with a first wireless protocol (adjusting a first wireless link) in response to receiving data via a second wireless link according to an embodiment of the present invention. Specifically, at 610, first wireless data is transmitted from an external portion of a hearing device to an implantable portion of a hearing device via a first wireless link operating according to a first wireless protocol. For example, the external component 104 can transmit an audio stream to a cochlear implant 112. At 620, second wireless data is received from an external device via a second wireless link operating according to a second wireless protocol. For example, the external component 104 or the cochlear implant 112 can receive a second audio stream from an external device using a second wireless protocol. At 630, operations associated with the first wireless protocol are adjusted based on operations of the second wireless protocol. For example, a compression ratio of a codec can be adjusted to change a bit rate associated with the first wireless link and / or a number of retransmissions associated with the first wireless link can be adjusted.

In other examples, the stimulator assembly 730 is a vibration actuator, which is arranged inside or outside the housing of the implantable device 30 and is configured to generate vibration. The vibration actuator receives the stimulation signal 715 and generates a mechanical output force in the form of vibration based on the stimulation signal. The actuator can deliver vibration to the recipient's skull in a manner that generates movement or vibration of the recipient's skull, thereby generating hearing perception by activating the hair cells in the recipient's cochlea via cochlear fluid movement.

As shown, the vestibular stimulator system 802 includes an implantable component (vestibular stimulator) 812 and an external device / component 804 (e.g., an external processing device, a battery charger, a remote controller, etc.). The external device 804 includes a transceiver unit 860. Thus, the external device 804 is configured to transmit data (and possible power) to the vestibular stimulator 812.

[0074] The vestibular stimulator 812 includes an implant body (main module) 834, a lead region 836, and a stimulation assembly 816, all configured to be implanted below the skin / tissue (tissue) 815 of a recipient.

[0078] Fig. 9 A retinal prosthesis system 901 is shown, which includes an external device 910 (which may correspond to the wearable device 100) configured to communicate with the retinal prosthesis 900 via a signal 951. The retinal prosthesis 900 includes an implanted processing module 925 (e.g., which may correspond to the implantable device 30), and a retinal prosthesis sensor-stimulator 990 is positioned near the retina of the recipient. The external device 910 and the processing module 925 can communicate via the coils 108, 20.

[0079] In an example, sensory input (e.g., photons entering the eye) is absorbed by a microelectronic array of a sensor-stimulator 990, which is hybridized with a glass piece 992 that includes, for example, an embedded microwire array.

The image processor 923 processes the input into the sensor-stimulator 990 and provides a control signal back to the sensor-stimulator 990 so that the device can provide an output to the optic nerve. That is, in an alternative example, the processing is performed by a component close to or integrated with the sensor-stimulator 990. The charge generated by the conversion of the incident photon is converted into a proportional amount of electronic current, which is input to the nearby retinal cell layer. The cells are excited, and the signal is sent to the optic nerve, thereby causing visual perception.
