Adaptive Channel Mapping for Wireless Hearing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices with limited battery, processing power, and transceivers face challenges in performing channel assessment for wireless connections, particularly in hearing devices that need to manage multiple piconets and scatternets, leading to inefficient communication due to interference and resource constraints.
Innovation Solution
The solution involves using the channel map of a primary wireless connection to reduce the burden on secondary wireless connections by designating an intermediary device as a slave in the primary connection, allowing it to access and manage channels effectively, while reserving channels to avoid interference and adapt to changing RF conditions through rotation and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices perform channel assessment for multiple wireless connections independently, then communication reliability is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent merges the channel assessment function across multiple wireless connections by having the primary connection's master device perform channel assessment for both connections. The secondary connection's slave devices use the primary connection's channel map, eliminating redundant assessment operations and reducing overall system complexity while maintaining communication reliability.
Solution Approach 2:
The primary connection's master device performs a multi-functional role by conducting channel assessment for both the primary and secondary wireless connections. This universal approach allows a single device to serve multiple connections, reducing the burden on individual devices while ensuring reliable communication across all connections.
2Reliability
If devices perform channel assessment for multiple wireless connections independently, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The patent merges the channel assessment function across multiple wireless connections by having the primary connection's master device perform channel assessment for both connections. The secondary connection's slave devices use the primary connection's channel map, eliminating redundant assessment operations and reducing overall system complexity while maintaining communication reliability.
Solution Approach 2:
The secondary connection's slave devices benefit from the primary connection's channel assessment work by reusing its channel map. This self-service approach allows the secondary connection to establish reliable communication without independently performing energy-intensive channel assessment, thus reducing overall energy consumption while maintaining reliability.
3Reliability
If channels are reserved to avoid interference, then communication reliability is improved, but adaptability to changing RF conditions decreases
Solution Approach 1:
The patent implements dynamic channel management where the channel map is periodically updated based on current RF conditions. The master device can modify channel assignments and allocations in response to changing interference patterns, allowing the system to adapt dynamically while maintaining reliability through coordinated channel usage and reservation mechanisms.

AI summary
Examples of devices, methods, systems, and machine readable media for reducing the burden of a master device of a second wireless connection by utilizing the channel map of a first wireless connection are provided. Since both the first and second wireless connections are located at nearly the same location, the “good channels” are very similar for both connections. Therefore a second wireless connection may take advantage of the channel assessment conducted by a first wireless connection in identifying channels by using one or more channels of the first wireless connection for communications in the second wireless connection.
