(en)An alerting system for deaf or hard of hearing people comprises a wireless network with one or more transmitters adapted to detect events and, upon detecting an event, to transmit a wireless alerting signal to one or more receivers adapted to alert a user. The wireless network is adapted to send an alerting signal to an electronic device in order to allow the electronic device to function as a gateway between said wireless network and a hearing aid device.

7.Description:
(en)The invention relates to an alerting system for deaf or hard of hearing people, said alerting system comprising a wireless network with one or more transmitters adapted to detect events and, upon detecting an event, to transmit a wireless alerting signal to one or more receivers adapted to alert a user. The invention relates to a corresponding application software to be implemented in an electronic device.
Alerting systems for deaf or hard of hearing people have been on the market for a long time. See for example the technical manual of the applicant “Technical Solutions”, English 1.4, 2009, 204 pages, to be downloaded under www.bellman.com. Such modular alerting systems comprise for example transmitters for detecting events like incoming calls on landline telephones or incoming skype calls, smoke alarm, door bell ringing or baby cry. In case a transmitter detects such an event, it sends an alerting signal to one or more receivers, like wrist receiver, pager receiver, alarm clock, portable receiver, flash receiver, portable flash receiver. The receiver alerts a user either directly, or by activating a separate alerting device, for example a bed shaker.
It is desirable to alert a user through a hearing aid device in case of an alerting signal transmitted from a transmitter of the wireless network. Towards this aim, US 2007/009124 A1 discloses a hearing aid device comprising a transceiver for interconnection of the hearing aid device with a wireless network for communication with a plurality of other devices, like door bell, mobile phone, cordless phone, TV set, fitting instrument, and a communication controller that is adapted for controlling data exchange through the network in accordance with a simple proprietary network protocol. Here, the hearing aid device of this prior art is integrated into the wireless network as a network component. However, since hearing aid devices are usually small, the range of the user will be limited, for the following reasons. For one, it is very difficult to integrate a large antenna into the hearing aid device. Furthermore, electronics adapted to the special transmission frequency used in the wireless network must be integrated into the hearing aid device, which is a complex and expensive task. Generally, an important feature of the radio protocol and radio technology integrated in the hearing aid device is that the energy consumption is very low. This requirement makes it even more difficult to use a standardized protocol, or a protocol used in the wireless network.
The problem underlying the present invention is to provide an alerting system and an application software which allow to alert a user through a hearing aid device in case of an alerting signal transmitted from a transmitter in the wireless network in a simple manner and with significantly increased range.
The invention solves this problem with the features of the independent claims. By using an electronic device functioning as a gateway between the wireless network and a hearing aid device, the hearing aid device is notified of an alerting signal from the wireless network via said electronic device, only, i.e. without direct connection between the wireless network and the hearing aid device. In this manner it is possible to alert a user through a hearing aid device in case of an alerting signal transmitted from a transmitter of the wireless network. Most important, since the electronic device can be larger than the hearing aid device, the components defining the range relative to the wireless network, like antenna and radio electronics, to be integrated into the electronic device can be made much larger, such that the range of the user carrying the hearing aid device relative to the wireless network can be dramatically increased as compared to the prior art. According to the invention, therefore, the hearing aid device advantageously is not a network component of the wireless network. Furthermore, according to the invention the integration of the wireless network can be simplified.
The electronic device may in particular be a smart electronic device like a smart phone, a tablet computer, also called tablet or smart pad or a phablet. The smart electronic devices that are capable of implementing the application software and function to form an interface to the hearing aid device advantageously comprise standardized connectivity technologies, for example, but not limited to, Bluetooth Low Energy, GSM, 3G, 4G, WiFi and/or Internet access technology. The electronic device may also be a mobile phone, in particular a Bluetooth capable mobile phone, a mobile electronic device, a mobile communication device, a personal electronic device, a smart watch and/or a smart TV. The electronic device advantageously comprises a display, preferably a touch-sensitive display.
An aspect of the invention relates to an application software, in particular a mobile application software, also called mobile app or app, to be implemented in a electronic device, wherein the application software controls said electronic device to send a notification signal to a hearing aid device upon receiving an alerting signal from a wireless network for deaf and hard of hearing people.
Preferably the notification signal is transmitted from the electronic device to the hearing aid device using Bluetooth, in particular Bluetooth Low Energy. Bluetooth Low Energy, also known as BLE or Bluetooth Smart, relates to Bluetooth standard 4.0 or higher. Alternatively, the notification signal may be transmitted from the electronic device to the hearing aid device using a proprietary radio transmission standard of the hearing aid device manufacturer. Generally the notification signal is preferably transmitted from the electronic device to the hearing aid device on the ISM 2.4 GHz radio band.
The invention advantageously benefits from advanced wireless technology which has been introduced into hearing aid devices recently. The driver for this technology evolution is mainly the feature to stream audio directly from an accessory, like a remote microphone or an accessory connectable to an audio source like a TV or an audio system, to the hearing aid device. The advanced wireless technology preferably enables to create a direct link between the electronic device and the hearing aid device. This allows a user to get streamed sound like telephone speech and music from the electronic device to the hearing aid device. Applying this technology to the invention, the notification signal is preferably transmitted from the electronic device to the hearing aid device as an audio stream.
In some preferred embodiments of the invention, a transmitter and/or a receiver of the wireless network is adapted to transmit an alerting signal directly to the electronic device, in particular using Bluetooth, more particularly Bluetooth Low Energy. In other preferred embodiments of the invention, the alerting signal is transmitted from said wireless network to said electronic device via a cellular network.
Preferably the electronic device comprises a remote control function adapted to change settings of the hearing aid device. A separate remote control for controlling the characteristic and response of the hearing aid can be dispensed with. In other words, the electronic gateway device and the remote control are integrated into one electronic device, which usually is in near proximity to the user, typically in a pocket, over most of the time in which the user uses the hearing aid device.
In addition to alerting the user through the hearing aid device, the electronic device may preferably be adapted to provide a visual and/or tactile signal to a user upon receiving an alerting signal from said wireless network.
Further preferably, a pattern of an audio signal in the hearing aid device and/or the visual and/or tactile signal in the electronic device is different depending on the type of event that has caused the alerting signal in the wireless network. This may be settable by the user using the application software of the electronic device.
The application software in the electronic device preferably enables the user to customize or set the characteristic of the alerting signal to be sent to the hearing aid device. This may comprise setting which alarms are forwarded to the hearing aid device, and/or setting specific alerting sound characteristics. This function may also comprise setting at least one alerting mode in the electronic device, wherein signals from per-defined transmitters of the wireless network only are transmitted to the hearing aid device depending on the set alerting mode. For example, in a meeting mode only emergency alerts like smoke alarms are forwarded to the hearing aid device.

In addition to the alerting by the alerting receivers 20 to 23 of the wireless network 11 , according to the invention the user is alerted by the hearing aid device 19 through the smart electronic device 18 acting as a gateway in the case of an alerting event detected by one of the alerting sensors 12 - 17 . This will be explained in the following in more detail for different embodiments shown in FIGS. 1 to 4 .
In the embodiment of FIG. 1 , an alerting sensor 12 - 17 , upon detecting an event, directly transmits a BLE alerting signal to the smart electronic device 18 via the Bluetooth Low Energy connection 36 , which causes the smart electronic device 18 to send an alerting signal in the form of an audio stream to the hearing aid device 19 via the wireless radio connection 34 .

In this embodiment one of the receivers 20 to 23 preferably comprises a corresponding Bluetooth Low Energy sender 47 . This embodiment may be preferably over the embodiment of FIG. 1 since in principle only one BLE sender 47 is required. The BLE sender 47 may also be a stand-alone device, for example an alarm clock or a medicine dispenser.
In the embodiments of FIGS. 1 and 2 , an alerting signal received by the smart electronic device 18 via the BLE connection 36 , 37 can additionally be forwarded to another device via the internet or another data connection, for example via the cellular mobile communication network 28 . As an example, a bed shaker could be triggered using wire or a wireless connection, preferably BLE, by the electronic device 18 .
In the embodiment of FIG. 3 , an alerting sensor 12 - 17 , upon detecting an event, transmits a wireless alerting signal to the smart electronic device 18 via a radio connection 48 and a cellular mobile communication network 28 comprising a plurality of base stations 29 using a digital communication standard like GSM, 3G, 4G, WiFi, an Internet connection or the like, which causes the smart electronic device 18 to send an alerts ing signal in the form of an audio stream to the hearing aid device 19 via the wireless radio connection 34 . In this embodiment the transmitters 12 - 17 preferably comprise corresponding radio senders 49 - 54 adapted to communicate with the cellular mobile communication network 28 .
In the embodiment of FIG. 4 , an alerting receiver 20 - 23 of the wireless network 11 , upon receiving a wireless alerting signal from one of the transmitters 12 - 17 via the radio connection 24 , transmits a wireless alerting signal to the smart electronic device 18 via a radio connection 55 and a cellular mobile communication network 28 comprising a plurality of base stations 29 using a digital communication standard like GSM, 3G, 4G, WiFi, an Internet connection or the like, which causes the smart electronic device 18 to send an alerting signal in the form of an audio stream to the hearing aid device 19 via the wireless radio connection 34 . In this embodiment one of the receivers 20 to 23 preferably comprises a corresponding radio sender 56 adapted to communicate with the cellular mobile communication network 28 . This embodiment may be preferably over the embodiment of FIG. 3 since in principle only one radio sender 56 is required. The radio sender 56 may also be a stand-alone device.
The embodiments of FIGS. 1 to 4 can be combined, for example may one of the alerting receivers 20 - 23 comprise a BLE sender 47 and a radio sender 56 .
In all embodiments, the smart electronic device 18 may be used as a remote control to change the settings, in particular controlling the characteristic and response of the hearing aid device 19 , and for example to switch between different listening programs optimized for sound/noise environments such as “noisy background”, “music” etc., tone control and so-called zoom control. The above described remote control function may be realized in the same application software as the gateway function of forwarding an alerting signal from the wireless network 11 to the hearing aid device 19 . Alternatively, the remote control function may be realized in a separate remote control application software.
In addition to transmitting an alerting signal to the hearing is aid device 19 via the radio connection 34 , the smart electronic device 18 , upon receiving an alerting signal from the wireless network 11 directly or indirectly through the cellular network 28 , can provide a visual and/or tactile alerting signal to the user through the visual indicator 31 and/or the tactile actuator 32 .
A pattern of an audio signal in the hearing aid device 19 and/or the visual and/or tactile signal in the smart electronic device 18 may be different depending on the type of event that has caused the alerting signal in the wireless network, enabling the user to identify the source of the alert and to react appropriately. This may be settable by the user using the application software of the electronic device 18 .
