Sensory Prosthesis Broadcast Selection Through Signal Fingerprints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensory prostheses, such as hearing aids and cochlear implants, require manual selection of wireless broadcast channels, which can be inconvenient and suboptimal for recipients.
Innovation Solution
A system and method for sensory prostheses to automatically select a broadcast channel by comparing sensor data with broadcast data using fingerprints, allowing seamless switching between sensor and broadcast-based stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection of wireless broadcast channels is used, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The sensory prosthesis automatically performs broadcast channel selection by comparing sensor samples with broadcast samples, enabling the device to serve itself without requiring manual user intervention for channel selection
Solution Approach 2:
The system pre-computes and stores fingerprints for multiple candidate broadcasts, allowing the automatic selection process to quickly identify and switch to the appropriate broadcast channel when needed
2Ease of operation
If automatic broadcast selection is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system creates simplified fingerprint representations (copies) of broadcast signals and sensor data, allowing complex broadcast content to be compared through compact digital signatures rather than full signal analysis
Solution Approach 2:
Fingerprints serve as an intermediary representation between the complex broadcast signals and the selection logic, enabling automated channel selection through simple fingerprint matching algorithms

AI summary
Disclosed technology includes a sensory prosthesis configured to automatically select a broadcast channel based on a comparison with a signal from a sensor of the sensory prosthesis. In an example, a sound processor automatically connects to an appropriate wireless broadcast audio channel by comparing the sound the sound processor receives on a microphone with the audio the sound processor receives from each of the wireless broadcast channels that the sound processor can receive. If the sound processor finds a match between the sound from the microphone and the sound from a broadcast, then the sound processor automatically selects the matching wireless broadcast channel. The sound processor then provides auditory stimulation to the recipient based on the selected broadcast channel.
