Abstract

A system and method for wireless streaming link break-in is disclosed. A first device transmits digital packets to a second device over a wireless streaming link. A third device synchronizes itself with the second device. Once the third device is synchronized with the second device, the third device transmits command request packets to the second device during a data receive window. The wireless streaming link is inactive during the data receive window. The second device responds to the request during a next data receive window.

Claims

1. A system comprising:

a first device configured to transmit over a first group of frequency channels via a synchronous communication link a first type of digital packets to a second device; and

a third device configured to transmit over a second group of frequency channels via an asynchronous communication link a second type of digital packets to the second device, wherein;

the first group of frequency channels is non-overlapping with the second group of frequency channels,

the second device is a hearing prosthesis that includes;

(1) a data interface configured to listen for (i) the first type of digital packets on the first group of frequency channels and (ii) the second type of digital packets on the second group of frequency channels, (2) a sound processor configured to receive audio and to generate instructions for generating and applying output signals to an ear, and (3) an output signal interface configure to generate and apply the output signals to the ear, and

the second device communicates with the third device in a bidirectional manner.

3. The system of claim 1, wherein the first type of digital packets includes digital audio data.

4. The system of claim 1, wherein the second type of digital packets includes digital control data.

5. The system of claim 1, wherein the first device is a device with data streaming capabilities.

6. The system of claim 1, wherein the third device is a remote control that controls at least the second device.

17. The system of claim 1, wherein, in response to the second device receiving the second type of digital packets transmitted by the third device, the second device and the third device are further configured to synchronize communications over the asynchronous communication link without the second device transmitting a beacon signal.

20. The system of claim 1, wherein the data interface is further configured to listen for the second type of digital packets at evenly spaced intervals in time.

2. A system comprising;

a synchronous communication network in which a hearing prosthesis receives digital signals from an external device in a first group of timeslots, wherein a first group of one or more frequency channels is used in the synchronous communication network; and

an asynchronous communication network in which the hearing prosthesis listens for and responds to digital requests from a remote control device in a second group of timeslots, wherein;

multiple timeslots in the first group of timeslots separate timeslots in the second group of timeslots,

a second group of one or more frequency channels is used in the asynchronous communication network, wherein the first group of one or more frequency channels is non-overlapping with the second group of one or more frequency channels,

the hearing prosthesis communicates with the remote control in a bidirectional manner,

and the hearing prosthesis comprises (1) a sound processor configured to receive audio and to generate instructions for generating and applying output signals to an ear, and (2) an output signal interface configure to generate and apply the output signals to the ear.

7. A system comprising;

a synchronous communication network in which a hearing prosthesis receives digital signals from an external device in a first group of timeslots, wherein a first group of one or more frequency channels is used in the synchronous communication network; and

an asynchronous communication network in which the hearing prosthesis listens for and responds to digital requests from a remote control device in a second group of timeslots, wherein;

multiple timeslots in the first group of timeslots separate timeslots in the second group of timeslots,

a second group of one or more frequency channels is used in the asynchronous communication network, wherein the first group of one or more frequency channels is non-overlapping with the second group of one or more frequency channels,

and the hearing prosthesis comprises (1) a sound processor configured to receive audio and to generate instructions for generating and applying output signals to an ear, and (2) an output signal interface configure to generate and apply the output signals to the ear.

8. The system of claim 7, wherein the synchronous communication network is one or more of a Time Division Multiple Access (TDMA) communication network, a slow Frequency Hopping Spread Spectrum (FHSS) communication network, a Frequency Agility (FA) communication network, or a Slow Frequency Agility (SFA) communication network.

9. The system of claim 7, wherein the asynchronous communication network is one or more of a slow FHSS communication network, an FA communication network, or an SFA communication network.

10. The system of claim 7, wherein the external device streams the digital signals to the hearing prosthesis.

18. The system of claim 7, wherein, in response to the hearing prosthesis responding to the digital request from the remote control device, the hearing prosthesis and the remote control are configured to synchronize communications over the asynchronous communication network without the hearing prosthesis transmitting a beacon signal.

11. A method comprising:

while a hearing prosthesis is receiving digital data transmissions in a first group of timeslots, sending synchronization request packets to the hearing prosthesis until receiving an acknowledgement signal from the hearing prosthesis, wherein the hearing prosthesis comprises (1) a sound processor configured to receive audio and to generate instructions for generating and applying output signals to an ear and (2) an output signal interface configure to generate and apply the output signals to the ear;

upon receiving the acknowledgement signal, sending to the hearing prosthesis a command request in a first timeslot included in a second group of timeslots;

receiving from the hearing prosthesis a response to the command request in a second timeslot included in the second group of timeslots; and

communicating with the hearing prosthesis in a bidirectional manner,

wherein the first group of timeslots is spread across a first group of frequency channels and the second group of timeslots is spread across a second group of frequency channels, wherein the first group of frequency channels is non-overlapping with the second group of frequency channels.

12. The method of claim 11, wherein the command request includes one of:

a request for status information, wherein the response to the command request includes the status information, or

a request to adjust settings, wherein the response to the command request includes information regarding setting adjustments.

13. The method of claim 11, wherein sending the request packets includes sending multiple request packets in quick succession, wherein each of the multiple request packets is sent via a different frequency channel.

14. The method of claim 11, wherein sending the request packets includes using a timing pattern designed to cause the hearing prosthesis to receive one of the synchronization request packets in a timeslot in the second group of timeslots.

15. The method of claim 11, wherein sending the command request includes sending the command request multiple times.
