Plain-Language Overview of Independent Claims:
This patent contains two independent claims, which define the core of the invention.
Claim 1: This claim describes a pair of eyeglasses with built-in electronics for hearing enhancement. The key features are:
- The glasses have a speaker, a wireless receiver, a power source (battery), and a processor, all housed within one of the temples (the "arms" of the glasses).
- The system can receive audio wirelessly from an external device (like a smartphone).
- Crucially, the processor is configured to act as a hearing aid by adjusting the audio based on the user's specific hearing profile.
Claim 16: This claim describes the method of using a head-worn device (like the glasses in Claim 1) to provide enhanced audio. The steps are:
- Receiving audio signals wirelessly.
- Processing these signals.
- Applying a personalized hearing enhancement by altering the signals according to the user's hearing profile.
- Playing the adjusted audio through a built-in speaker.
- The entire system is powered by a battery contained within the head-worn device.
