Abstract
An exemplary wearable brain interface system includes a head-mountable component and a control system. The head-mountable component includes an array of photodetectors that includes a photodetector comprising a single-photon avalanche diode (SPAD) and a fast-gating circuit configured to arm and disarm the SPAD. The control system is for controlling a current drawn by the array of photodetectors.

A wearable brain interface system comprising:
- a head-mountable component comprising an array of photodetectors that includes a photodetector comprising:
- a single-photon avalanche diode (SPAD), and
- a fast-gating circuit configured to arm and disarm the SPAD;
- and
- a control system for controlling a current drawn by the array of photodetectors.

A wearable brain interface system comprising:
- a head-mountable component comprising an array of photodetectors that includes a photodetector comprising:
- a single photon avalanche diode (SPAD), and
- a fast-gating circuit configured to arm and disarm the SPAD;
- and
- a control system comprising a plurality of switches connected in parallel to the SPAD, the control system configured to control a current drawn by the array of photodetectors by controlling the plurality of switches to control a slew rate of the fast-gating circuit.

A wearable brain interface system comprising:
- a head-mountable component comprising an array of photodetectors that includes a photodetector comprising:
- a single photon avalanche diode (SPAD), and
- a fast-gating circuit configured to arm and disarm the SPAD;
- and
- a control system configured to control a current drawn by the array of photodetectors by abstaining from disarming the SPAD during one or more measurement time periods.
