Non-invasive wearable brain interface systems including a headgear and a plurality of self-contained photodetector units configured to removably attach to the headgear
First Claim
1. A non-invasive wearable brain interface system comprising:
- a headgear configured to be worn on a head of a user;
a plurality of self-contained photodetector units configured to removably attach to the headgear, the photodetector units each comprising a plurality of photodetectors configured to detect photons of light after the photons reflect from a target within a brain of the user; and
a master control unit communicatively coupled to each of the photodetector units by way of a plurality of wires and configured to control the photodetector units, the master control unit comprising an input power port configured to connect to a power cable that provides power from a power source for the master control unit and the photodetector units.

Abstract
An exemplary non-invasive wearable brain interface system includes a headgear configured to be worn on a head of the user and a plurality of self-contained photodetector units configured to removably attach to the headgear. The photodetector units each include a plurality of photodetectors configured to detect photons of light after the photons reflect from a target within a brain of the user. The brain interface system further includes a master control unit communicatively coupled to each of the photodetector units by way of a plurality of wires and configured to control the photodetector units, the master control unit comprising an input power port configured to connect to a power cable that provides power from a power source for the master control unit and the photodetector units.
