The invention relates to the field of hearing devices. It relates to methods and apparatuses according to the opening clauses of the claims, in particular to a method and a system for maintaining a hearing device and to a method and a system for dispensing consumables or accessories for a hearing device.
Under “hearing device” a device is understood, which is worn adjacent to or in an individual's ear with the intent to improve the individual's hearing capacity. Such improvement may also be barring acoustical signals from being perceived in the sense of hearing protection for the individual. If the hearing device is tailored so as to improve the perception of a hearing impaired individual towards the hearing perception of an individual with ordinary hearing, then we speak of a hearing-aid device. With respect to the application area, a hearing device may be applied behind the ear, in the ear, completely in the ear canal or may be implanted.
A system comprising at least one hearing device is referred to as “hearing system”. Typically, a hearing system comprises two hearing devices. Further devices of a hearing system can be, e.g., remote controls.
Hearing devices usually have to be adjusted to the needs and preferences of the user of the hearing device. This adjusting, also referred to as fitting, is typically done during several fitting sessions. The fitting may involve the measurement of audiograms and other audiological data of the user, an initial fitting and several steps of fine-tuning the fitting as well as the definition of several hearing programs providing for an optimized hearing sensation in different acoustic environments. This is known, in particular, in the field of hearing-aid devices. Hearing device fitting requires very specific skills, and it is different for different hearing device users, since the hearing abilities of each user are very individual. Therefore, the fitting and the corresponding programming of the hearing devices is usually done by an audiologist or another hearing care professional.
Typically, the hearing care professional has a programming environment with one or several computers, each of which has an interface unit to connect to a hearing device or to a pair of hearing devices. The provision of several computers allows working with several hearing device users at the same time, typically in different examination rooms. Hearing devices of different hearing device manufacturers require the use of different programming software for fitting, also referred to as fitting programs. In order to simplify dealing with different fitting programs, software-hardware platforms with dedicated interfaces have been developed, which allow to connect hearing devices of different hearing device manufacturers to said dedicated interface attached to a general purpose computer. By means of the software of such a software-hardware platform, a hearing-device-manufacturer-specific fitting program can be launched, with the information, what kind of hearing device model shall be fitted and for which specific user the hearing device shall be fitted. This way, the appropriate type and version of the hearing-device-manufacturer-specific fitting program is launched, or appropriate parameters in the hearing-device-manufacturer-specific fitting program are set, and data related to the hearing of the user, like audiograms, as well as former hearing device settings, are in access and used in the hearing-device-manufacturer-specific fitting program. A well-known example of such a software-hardware platform in the field of hearing-aid devices is known as “NOAH”.
The invention arose from the desire for time savings in fitting sessions, without decreasing the quality of the fitting.
It has turned out that it takes a considerable amount of time to launch a fitting software, even if performed by a software-hardware platform as described above.
The inventive ideas solving that problem turned out to be applicable to further problems, too, like the dispensing of consumables or accessories for hearing devices.
The unpublished patent applications with the application numbers U.S. Ser. No. 11/395,788 and EP 06 112 108.3 of the same applicant, filed on Mar. 31, 2006, and entitled “Method and system for adjusting a hearing device”, disclose a method for wirelessly adjusting one or more hearing devices, by using a wireless network or wireless transmitter, respectively. By means of this, an audiologist can unambiguously assign one or two hearing devices in a fitting session, even if multiple hearing devices lie on the desktop within the range of the wireless network or wireless transmitter, respectively.
US 2002/0054689 A1 discloses a method and a system for remotely upgrading a hearing device by downloading software resources over a network from a remote server to a local client.
As has been depicted above, one objective of the present invention is to provide a method and an arrangement, which allow time savings in fitting sessions. In particular, a method for maintaining a hearing device and a system for maintaining a hearing device shall be provided.
In addition, a method for dispensing consumables or accessories for a hearing system, and a system for dispensing consumables or accessories for a hearing system are provided. An objective of these is to simplify said dispensing. Another objective thereof is to avoid mistakes in dispensing said consumables or accessories. Such mistakes could occur, e.g., during manual dispensing, when a consumable or accessory is selected and dispensed, that is not suitable for the specific hearing system, though it might be appropriate for another type or model of hearing device.
Further objects emerge from the description and embodiments below.
At least one of these objectives is at least partially achieved by a method or by an arrangement or system according to the invention.
The method comprises the steps of
The arrangement comprises
Accordingly, in an automated fashion, it is detected, that said specific user of said specific hearing system is expected to have an event concerning the hearing system in the near future, e.g. an interaction between the user and his hearing care professional. This interaction may be a scheduled or unscheduled meeting of said user with the user's hearing care professional or a person related to (in particular working for) said hearing care professional, or a scheduled or unscheduled interaction of said user with a hearing-device-related apparatus, e.g., a machine or computer associated with a hearing care professional, typically located at or near the hearing care professional's office.
A hearing care professional is a person professionally concerned with hearing devices, e.g., an audiologist, a hearing aid dispenser or another person who is responsible for support or maintenance for a hearing device or for purchasing a hearing device.
The term “automatically”, e.g., in the above-mentioned “automatically monitoring or detecting”, means that the corresponding process is accomplished in a machine-controlled manner, with no need for support of an individual required to accomplish the task, e.g. said monitoring or detecting.
After detecting that said forthcoming event is to be expected, the user and/or his hearing system is identified and said identification data are obtained. Preferably, also this step is carried out automatically, since this way, time can be saved and manual actions and the occurrence of mistakes can be reduced. Said identification data can comprise, e.g., the specific user's name or client number, or the model and serial number of the at least one specific device. Preferably, said identification data are unique with respect to each user or each hearing device respectively, since this way, mix-ups and mistakes can be avoided.
Then, said data related to a multitude of users and/or to a multitude of hearing systems is accessed, and by means of said identification data, said data related to said specific user and/or to said specific hearing system are obtained. This is preferably carried out automatically, too, since this way, time can be saved and manual actions and mistakes can be reduced. The retrieved device data or user data can be for instance the specific user's audiological data or other data related to the hearing of the user, the type of battery suitable for said specific hearing system or the specific user's name.
Said identification data, said device data and said user data are usually data in digital form.
Said identification data, device data and user data are preferably stored electronically, in particular in a computer memory.
In one embodiment, said event is an interaction, e.g. a service action providing service for said specific user and/or for said specific hearing system, in particular involving the physical presence of said specific user and of at least one device of said specific hearing system. In particular, such a service action for said specific user and/or for said specific hearing system comprises at least one of the group comprising
In one embodiment, which corresponds to a first aspect of the invention, said automatically monitoring or detecting said event comprises detecting that the term of a scheduled appointment with said specific user is due within an adjustable or predeterminable period.
In the corresponding arrangement, said detecting module comprises a detector for detecting that the term of a scheduled appointment with said specific user is due within an adjustable or predeterminable period.
Nowadays, it is quite common to manage appointments by means of an electronic appointment book or electronic calendar, typically implemented as a program running on a computer or personal digital assistant. Said detector can, e.g. continuously compare the current time with the points in time of scheduled appointments entered in said program. E.g., five, ten or fifteen minutes before an appointment is due, identity data are extracted from the electronic appointment book in form of the name of the specific user having said appointment and further action can be taken, e.g., retrieving data related to said specific user from the database.
In another embodiment, which corresponds to a second aspect of the invention, said automatically monitoring or detecting of said indications comprises detecting, by means of a detector, that said specific device is located within an adjustable or predeterminable detection range of said detector.
In particular, it may comprise detecting that said specific device is located within the range of a wireless network to which said specific device is responsive.
In the corresponding arrangement, said detecting module comprises a detector for detecting that said specific device is located within an adjustable or predeterminable detection range of said detector.
In particular, it may comprise a detector for detecting that said specific device is located within an adjustable or predeterminable range of a wireless network or wireless communication device to which said specific device is responsive.
Accordingly, the physical presence of said specific device or said specific hearing system respectively in the detection area of the detector is detected. Preferably, this is done in a non-contact, wireless fashion. This may be accomplished, e.g., by RFID (radio frequency identification) with an RFID chip provided in or at the at least one specific device and a corresponding RFID reader near the entrance of the hearing care professional's office. Other proximity-detecting techniques may be used as well. The identification data may as well be transmitted using RFID.
A preferred way of detecting the physical presence of said at least one specific device makes use of the fact, that nowadays many hearing device are provided with wireless network capabilities, which are typically used for communicating within a hearing system comprising, in addition to one hearing device, another hearing device and/or a remote control, or for receiving audio signals from a remote microphone. Hearing devices with wireless network capabilities are known in the art, e.g., in the field of hearing-aid devices. The use of said wireless network capabilities for proximity sensing has the advantage, that it can be realized with existing technology. Near the entrance of the hearing care professional's office, means for establishing a wireless network can be foreseen, and said detection of said indication indicative of said forthcoming interaction can be accomplished by recognizing that the hearing system connects to said wireless network, wherein already the connection of only one device of the hearing system to the wireless network means a connection of the hearing system to the wireless network. The identification of the specific user and/or specific hearing system may also be accomplished by means of said wireless network.
The physical presence of said specific hearing system is a very good indicator for the physical presence of said specific user, since hearing systems usually worn or carried by the user. Accordingly, it can be expected that the user, when his presence is detected, wants to see his hearing care professional or a related person like the receptionist for some—scheduled or unscheduled—appointment, an examination, a repair request, a purchase or for some other interaction.
In one embodiment, which applies to the first as well as to the second aspect of the invention, the method comprises the step of launching a program, in particular a fitting program, suitable for said specific hearing system upon receiving launching data, which are derived in dependence of said identification data or identical with said identification data.
The corresponding arrangement comprises a launching module operationally connected to said identifying module and/or to said data accession module, for launching a program, in particular a fitting program, suitable for said specific hearing system upon said output of said identification data and/or upon receiving launching data, which are derived in dependence of said identification data or identical with said identification data.
As has been indicated before, it usually takes a considerable amount of time to launch a fitting program suitable for a specific hearing system. Instead of manually launching the fitting program, the invention allows to do this before the fitting session has started, even in an automated fashion. After it has been detected that there will be an interaction with the user, in particular a fitting session, the suitable program can be launched. When the specific user and the hearing care professional will have entered the examination room, in which the computer with the fitting program is located, the appropriate fitting software will already be running, and no time is wasted by manually launching the program while said specific user and said hearing care professional have to wait for the launching process to finish.
In one embodiment of this method, said device data or user data are retrieved or accessed by said program, and in particular, wherein said device date or user data comprise data related to the hearing of said specific user.
In the corresponding arrangement, said data accession module is operationally connected to said program and provides said program with said device data or user data, in particular wherein said device date or user data comprise data related to the hearing of said specific user, in particular audiological data of said specific user.
This way, not only the suitable fitting program can be launched in advance, but the fitting program may also be provided with the appropriate data related to the user, in particular, related to the hearing of the user.
In one embodiment, which applies to the first as well as to the second aspect of the invention, the method comprises the step of loading data-logging data from said specific hearing system.
The corresponding arrangement comprises a data loader initiating a procedure for loading data-logging data from said specific hearing system. Data logging and corresponding embodiments are described below in conjunction with the Figures. Said loading is preferably accomplished in a wireless fashion.
It is possible to carry out all steps of the described methods automatically. This allows for a full automation and corresponding time savings.
In one embodiment of the arrangement, said data source is comprised in the arrangement.
A method according to the invention can, in one embodiment, be a method for maintaining a specific hearing system, and a system according to the invention can, in one embodiment, be a system for maintaining a specific hearing system.
A method for maintaining a specific hearing system may comprise the step of using a program suitable for said specific hearing system for adjusting said specific hearing system.
A system for maintaining a specific hearing system may comprise a computer on which a program suitable for said specific hearing system is running or at least installed.
The expression “maintaining a hearing device” comprises at least fitting and adjusting, updating, repairing and checking a hearing device.
A method according to the invention can, in one embodiment, be a method for dispensing consumables or accessories for a specific hearing system, and a system according to the invention can, in one embodiment, be a system for dispensing consumables or accessories for a specific hearing system.
In one embodiment of said method for dispensing consumables or accessories for a specific hearing system, said identification data are related to said specific device, and the method comprises the step of selecting a consumable or accessory suitable for said specific hearing system in dependence of said identification data.
In addition, it may comprise the step of dispensing said consumable or accessory.
In one embodiment, said system for dispensing consumables or accessories for a specific hearing system comprises a selecting module for selecting a consumable or accessory suitable for said specific hearing system, wherein said selection is made in dependence of said identification data.
In addition, it may comprise a dispenser for dispensing said selected consumable or accessory.
Accordingly, such a system can be, e.g., an automatic dispensing machine working, e.g., as follows: A hearing device user with his at least one device of his hearing system approaches the automatic dispensing machine, which is detected by the machine. Thereupon, the at least one specific device of the hearing system is identified. Based on the corresponding identification data, the machine looks up, which type of consumable or accessory is suitable for the specific hearing system, selects a user-specified number of these suitable items and dispenses them upon user request. The method may include preparing or accomplishing a payment.
As far as the various parts of the arrangements and systems according to the invention are concerned (they are mostly termed “module”), these are basically functional units. Therefore, they may be arranged in various ways: groups of them can be fully or in part identical, and on the other hand, it is possible to realize any of them as separate units. For example, said identifying module may be separate from said detecting module or, at least in part, be identical with at least a part thereof.
The advantages of the methods correspond to the advantages of corresponding apparatuses.
Further preferred embodiments and advantages emerge from the dependent claims, the description and the figures.
Below, the invention is described in more detail by means of examples and the included drawings. The figures show schematically:
The reference symbols used in the figures and their meaning are summarized in the list of reference symbols. Generally, alike or alike-functioning parts are given the same or similar reference symbols. The described embodiments are meant as examples and shall not confine the invention.
Please note that in the figures, merely functionally-defined modules or units are drawn. When implemented in form of electronics or, in particular, in form of programs, i.e., computer software, it is, of course, possible to jointly implement several of these in one circuit or in one program, respectively.
As has been mentioned above, it is possible to divide the invention into at least two aspects, depending on how it is detected that an interaction with a user of a hearing system is to be expected.
According to the first aspect of the invention, the detection of a forthcoming interaction with the user of the hearing system is accomplished by detecting that the point in time of a scheduled appointment with said user is due within a prescribable span of time.
The system according to this embodiment comprises at least a detecting module 3, an identifying module 4 and a launching module 6. The detecting module 3 receives the current date and time t from a clock T and accesses the electronic calendar 20. When the detecting module 3 detects that an appointment listed in the electronic calendar 20 is scheduled to take place within a prescribable period, which in the case of the embodiment of
The detecting module 3 can be embodied as a program running on a general-purpose computer, e.g., the same on which the electronic calendar 20 is running. It is also possible to incorporate the function of the detecting module 3 in the electronic calendar 20.
When the identifying module 4 has been notified that an indication of a forthcoming appointment has been detected, the identifying module 4 will obtain data 40 identifying the respective user from the electronic calendar 20. These data 40 are also referred to as identification data 40. They are identical with the data stored in the electronic calendar 20 or with a part thereof. The identifying module 4 passes on the identification data 40 to the launching module 6.
It is advisable to foresee that the identification data 40 are unique with respect to each specific user, at least within the environment of one hearing care professional.
The identifying module 4 can be embodied as a program running on a general-purpose computer, e.g., the same on which the electronic calendar is running. It is also possible to incorporate the function of the identifying module 4 in the electronic calendar 20.
The launching module 6 can be embodied as a program running on a general-purpose computer, e.g., the same on which the electronic calendar 20 is running. It is also possible to incorporate the function of the launching module 6 in the electronic calendar 20.
It is furthermore possible to jointly implement the detection module 3 and the identifying module 4 together with the launching module 6, as indicated in
Upon receiving the identifying data 40, the launching module 6 passes on the identifying data 40 as launching data 6a to a general-purpose computer 600, which may be—but typically is not—identical with the general-purpose computer on which the electronic calendar 20 is running.
There are two ways to interpret the following steps.
In a first interpretation, there is already a program 60 running, which is suitable for the specific hearing system of the user who is expected to turn up for the scheduled appointment. This program 60 is advised by the launching module 6 to access and retrieve data 50 related to said user and/or to his hearing system. Such data 50 may, in particular, be audiological data of said user or other data related to the hearing of the user. Such kinds of data are usually contained in a database 5 containing such kind of data for a multitude of users and/or for a multitude of hearing systems. For retrieving these data 50, said program 60 uses a database accession module 5a, which may itself be a program, and which may be incorporated in the database, incorporated in the program 60 or separate from these.
Typically, a fitting program, i.e., a program for adjusting a hearing system or a hearing device, is envisaged as said program 60.
In a second interpretation, a program 60 as described above is launched on the computer 600 upon receiving the launching data 6a. By means of the launching data 6a a suitable program 60 to be launched can be chosen. The program can then, typically based on the launching data 6a, retrieve data related to the specific user and/or to the specific user's hearing system in the manner described before.
An advantage of an embodiment according to
The embodiment illustrated in
One hearing care professional typically deals with hearing devices of various manufacturers, and each hearing device manufacturer typically has its own fitting program or even different fitting programs for different hearing device models. Accordingly, in order to be able to launch that one specific program, which is suitable for the specific hearing system of the user having the appointment, rather detailed information on the hearing system is required. Furthermore, within the suitable program, usually the user of the specific hearing system has to be known in order to be able to retrieve the user-related data, e.g., audiograms, history of the fitting process and other data related to the hearing of the specific user.
Therefore, the identifying unit 4, after having received the identifying data 40, accesses, via said database accession module 5a′, the database 5 and retrieves data 50′. The database 5′ links identifying data 40, typically the user's name or a client number, to data, which either directly indicate the program 60 to be launched, or data from which the appropriate program 60 can be deduced. The latter data may be data indicating the manufacturer and model, possibly also the serial number, of the user's hearing system or of at least one device of the user's hearing system. The data retrieved from the database 5′ are, possibly together with the identification data 40, passed on to the launching module 6 as data 45 derived independence of the identification data 40.
These data 45, or data derived therefrom, are passed on from the launching module 6 to the computer 600 as launching data 6a. Thereupon, the appropriate program 60 can be launched and the appropriate user-related data can be loaded. All this can happen in an automated fashion.
Although the databases 5 and 5′ and the database accession modules 5a, 5a′ have been drawn separately in
Another embodiment is illustrated in
Therefore, the identifying module 4 outputs the data 45 derived in dependence of the identification data 40 to a messenger module 8, which initiates the transmission of a message 8a to the respective user. The messenger module 8 may be adapted to initiate the sending of
Said prescribable time span before the appointment is due is preferably chosen in dependence of the type of message to be transmitted. Examples: For an SMS message, the time span may be between 15 min and 4 hours (order of magnitude), for conventional mail 1 to 4 days, for fax and e-mail 12 hours to 3 days.
In this special embodiment illustrated in
The function of the messenger module 8 may be embodied separately from the identifying module 4, or jointly therewith. The specific database 5 of
From EP 1 414 271 and US 2004/0190739, hearing systems are known which are capable of data logging. Data logging means, that in a hearing device and/or in a recording unit at least temporally operationally connected to the hearing device, information is recorded (logged), which relates to a point in time of the recording and/or a recording frequency, and to data and/or parameters and/or adjustments of the hearing device. The point in time of the recording and/or the recording frequency and the type of information (corresponding to data) concerning the hearing device to be recorded can be adjusted or programmed. By means of data logging, a multitude of the parameters adjustable in the hearing system can be recorded in actually existing acoustic environments and thereafter be checked or surveyed altogether or selectively. Based on an analysis of the recorded information, the hearing system and, in particular hearing programs, can be adjusted, typically by the hearing care professional.
Since data logging as well as the corresponding data-logging data and the corresponding hearing devices and methods are described in great detail in the above-mentioned publications, it is referred to these publications for further details, and EP 1 414 271 and US 2004/0190739 are herewith incorporated by reference in this application.
The identifying module 4 may receive the information, that the specific hearing system of the user who is expected for the appointment is capable of data logging or not, either from the electronic calendar 20, in which possibly a special remark for data logging is made, or rather from the database 5 via the database accession module 5a. In the latter case, the database 5 typically comprises data related to a multitude of hearing systems, namely at least the information whether or not a hearing system is capable of data logging, and this information can be accessed via the identification data 40.
When the user's hearing system is capable of data logging, a loading procedure for loading the data-logging data from the specific hearing system 1 is initiated. In the example of
A data loading module 7 initiates the procedure for loading the data-logging data 7a, and it preferably receives appropriate contact information, e.g., a telephone number of the hearing system or the appropriate telecommunication device, e.g., from the identifying module 4, which may have obtained this appropriate contact information from the database 5 or from elsewhere, e.g., from the electronic calendar 20. The loading of the data-logging data 7a may be fully automated. It is also possible that the data loading module 7 requests the user to transmit the data-logging data 7a.
As indicated in
As has been indicated before, an analysis of the data-logging data 7a can provide valuable input for adjusting the hearing system 1. Therefore, said prescribable span of time will typically be between two hours and two days, thus allowing the hearing care professional to finish analyzing the data-logging data 7a before the appointment is going to take place and/or to analyze rather recent data-logging data 7a
When worded as a method, the somewhat generalized embodiment according to the first aspect of the invention can be described as a method for preparing a scheduled appointment of a specific user of a specific hearing system with a hearing care professional, comprising the steps of
When worded as an apparatus or arrangement, the somewhat generalized embodiment according to the first aspect of the invention can be described as an arrangement for preparing a scheduled appointment of a specific user of a specific hearing system with a hearing care professional, comprising
According to a second aspect of the invention, the detection of a forthcoming interaction with the user of the hearing system is accomplished by detecting, by means of a detector, that at least one device of the hearing system of the user is located within the detection range of said detector.
In this second aspect of the invention, also not-scheduled, spontaneous interactions can be dealt with.
The detector can be any proximity detector. It is sufficient that the detector is capable of detecting that an item to be detected is located within a detection range of the detector, wherein that detection range should be at least of the order of 0.1 m and at most of the order of 100 m, typically between 0.3 m and 10 m.
Wireless and non-contact methods for proximity detection are preferred.
For example, radio frequency identification (RFID), as commonly used in shops for detecting theft, can be used. It is also possible to implement the Bluetooth technology, which is commonly used for communication between computers and computer periphery and/or mobile communication devices and take advantage of the limited range of Bluetooth connections.
An advantageous way of detection makes use of the fact that hearing devices—and therefore also hearing systems—are known, which are capable of short-range wireless communication. Such hearing devices are disclosed, e.g., in U.S. Pat. No. 5,479,522, WO 01/54458 A2 and in WO 2004/110099 A2, where further details can be found, in particular regarding the communication networks and the involved devices. With respect to the second aspect of the invention, it can be made use of the limited range of a short-range network, namely by detecting the proximity of the hearing system user to, e.g., the office of the hearing care professional by detecting, e.g., that at least one device of the user's hearing system tries to connect to the short-range network established at the hearing care professional's office, or vice versa. Accordingly, the wireless network capability of a hearing system, which itself is known in the art, is used for proximity detection of the hearing system.
A detecting module 3 and, operationally connected thereto, an identifying module 4 are installed in a suitable location, e.g., near the entrance of the hearing care professional's office. The detecting module 3 comprises a detector having a detection range 101. When an object to be detected, i.e., in
The identifying module 4 thereupon obtains identification data 40 from the hearing device 11, which—preferably uniquely—identify the hearing system 1. Said identification data 40 are then fed to a launching module 6, like in the embodiment of
The detection of the hearing device 11 may be accomplished using a short-range communication capability of the hearing device 11, and also the identification of the hearing device 11 may be accomplished using a short-range communication capability of the hearing device 11. As indicated by the dashed rectangle in
E.g., the following scenario is possible using the embodiment of
The detecting/identifying part of the embodiment of
As indicated by the dashed rectangle, a detecting module 3 and an identifying module 4 form together with a transceiver 110 one unit capable of communicating with the hearing device 11. The transceiver 110 is continuously or quasi-continuously monitored by a program (the detecting module 3), which notifies another program (the identifying module 4) when a wireless connection has been newly established. Thereupon, the identifying module 4 requests, via the transceiver 110, identification data 40 from the hearing device 11. Having received the identification data 40 from the hearing device 11, the identifying module 4 retrieves, via a database access module 5a, data 50 from a database 5, which indicate whether or not hearing device 11 (or hearing system 1) is capable of data logging, or data 50, which indicate that it is assumed that hearing device 11 (or hearing system 1) currently has data-logging data to be downloaded. If data-logging data shall be downloaded, a data loading module 7 is instructed accordingly. Data loading module 7 instructs the transceiver 110 to download the data-logging data 7a from the hearing device 11 (or from another device of the hearing system 1), and stores the data-logging data 7a, e.g., in the database 5 using the database accession module 5a.
Another embodiment is illustrated in
The left part of
By means of the described battery dispensing vending machine, the dispensing of wrong batteries can be avoided, and the hearing system user does not need to know the precise model of his hearing system or what type of batteries are required for the hearing system 1.
In the embodiment of
Usually, the identification data 40 are stored in a memory module 10, typically some computer memory.
