New Patent #3 Issued December 10th, 2019 is US Patent No. 10,506,317
The claims are directed to a wireless communication “smart” ring (formatted to be worn on the finger).
The smart ring carries a microphone and a switch or button for “activating” the microphone.
Unique, ergonomically-important relationship between locations of the microphone and switch is claimed.
I believe consumers will demand this ergonomic-based relationship to be part of any successful “smart” ring with voice interface for a more private use in public locations and for best audio in less than ideal ambient conditions.
