THE PART THAT MATTERS

The controller chooses.

It may select active and reference electrodes, then measure using both subsets. EEG is one example.

THE SEARCH IS JUST THE START

Less hunting.
More understanding.

A mention is useful. Understanding what surrounds it is where the research begins.

Get the whole passage.

Read exact phrases in context, with publication details and stable evidence references. Keep the wording that makes a mention meaningful.

Make sense of the patterns.

Move from individual mentions to a technical map and an Oracle Overview. Follow the interpretation back to its supporting evidence.

Go back to the original.

Inspect available original PDFs and highlighted source pages. See where OCR was used, where sources are missing and what remains unverified.

THE PATENTORACLE READING
  1. 610 / Controller

    The controller chooses.

    It may choose an active subset and a reference subset, then perform a measurement test using both. EEG is one example.

  2. 608 / Electrode carrier

    The carrier connects.

    The hatched carrier holds the electrodes and may electrically couple them to the controller. The description names a flex or microaxial cables.

  3. 604a–604h / Active electrodes

    Eight active electrodes.

    These eight contacts form the active group shown here. The controller may select one or more; the drawing does not identify a chosen subset.

  4. 606a–606c / Reference electrodes

    Three reference electrodes.

    A reference subset is also selected. The measurement uses the selected active and reference subsets together.
