Eeg headsets with precise and consistent electrode positioning

This document discloses EEG headset designs that address shortcomings in prior art headsets and also provides headset solutions for new and useful applications utilizing EEG headsets. One such application is brain computer interface (BCI) applications, and more specifically, a BCI application for stroke therapy in which the headset is utilized to obtain ipsilateral brain signals. This document also discloses BCI devices and methods utilizing EEG headsets.

The abstract as published by the patent office, from US2017143228A1. It describes the invention; it is not a statement of what is protected.

  Electrodes and arrays

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B5/291, A61B5/6803, G06F3/011). The claims define what a patent protects, and they are not read here.

Surgical access

A probe soft enough for the brain to tolerate is too soft to push in by hand, and each route into the head has its own risk. The problem behind it: placing many contacts exactly, without injuring tissue or vessels, in an operation short and repeatable enough to offer widely.

Interface and electrodes

Everything downstream works with what the contacts pick up. Their number, size and distance from the neurons set the ceiling on the signal. The problem behind it: more contacts, closer to neurons, that still record after years in tissue that reacts to them.

Why the layer matters to the field, not a judgement of this filing. A patent family shows that protection was sought. It does not show that the technology was built, is used in a product, or works in people. The whole stack

Dates as the offices published them. Office records are in the offices' own words and are a selection: refusals, lapses and withdrawals, and records that name an owner. Each concerns one member of the family, not the family as a whole, and another member in the same office may stand. Whether a patent is in force today is not assessed.
