Abstract
One variation of a system for collecting biosignal data includes: a left junction; a right junction; a first band spanning the left and right junctions; a first band adjuster configured to adjust a length of the first band between the left and right junctions; a second band spanning the left and right junctions and radially offset from the first band about a lateral axis spanning the left and right junctions; a second band adjuster configured to adjust a length of the second band between the left and right junctions; a first electrode fixedly mounted to the first band and centered between the left and right junctions; a second electrode mounted to the first band offset from the first electrode and laterally-adjustable along the length of the first band; and a third electrode mounted to the second band and laterally-adjustable along the length of the second band.
Core Innovation
The invention is an adjustable electroencephalography headset having a left junction, a right junction, a first band with a first band section extending from the left junction, a second band section extending from the right junction, and a center section supported by the first band section and the second band section. A second band extends between the left junction and the right junction and is radially offset from the first band about a lateral axis spanning the left junction and the right junction. The headset includes a first electrode fixedly mounted to the center band section of the first band and approximately centered between the left junction and the right junction.
The headset also includes a second electrode mounted to the first band between the first electrode and the left junction. A first band adjuster is configured to extend and retract the first band section and the second band section approximately equally relative to the center section to adjust a first length of the first band over a first range of lengths between the left junction and the right junction. The first electrode remains approximately centered between the left junction and the right junction over the first range of lengths while the first band length is adjusted.
The invention further provides refinements including positional calibration and labeling using a length scale mapped to discrete electrode position labels aligned to a 10-20 EEG electrode configuration. A linear rack and electrode position labels are used to couple an electrode to discrete electrode positions across a second range, and a length value indicates a current length setting.
Claims Coverage
The independent claim coverage centers on an adjustable EEG headset architecture with left/right junction-supported bands and a band adjuster that changes the headset band length while maintaining an electrode approximately centered. Three core inventive features are identified from the provided claim text, with further refinements tied to 10-20 placement and discrete length-to-label electrode positioning.
Left and right junction-supported bands with radially offset second band
An adjustable electroencephalography headset comprising a left junction, a right junction, a first band with a first band section extending from the left junction, a second band section extending from the right junction, and a center section supported by the first band section and the second band section, and a second band extending between the left junction and the right junction and radially offset from the first band about a lateral axis spanning the left junction and the right junction.
Approximately centered fixed electrode maintained during band length adjustment
A first electrode fixedly mounted to the center band section of the first band and approximately centered between the left junction and the right junction, and a first band adjuster configured to extend and retract the first band section and the second band section approximately equally relative to the center section to adjust a first length of the first band over a first range of lengths between the left junction and the right junction with the first electrode remaining approximately centered between the left junction and the right junction over the first range of lengths.
Discrete length-scale mapped electrode position labels for current band setting
The headset includes a linear rack and electrode position labels to couple the second electrode to a first band across a second range of electrode positions, where the first band has a length scale mapped to discrete electrode position labels and indicates a current length setting by the selected length value.
Across the provided independent claim and associated refinements, the core claim coverage is directed to an adjustable EEG headset with junction-supported bands in which band length is extended or retracted while keeping a fixed electrode approximately centered between the junctions. The remaining claim detail addresses a second electrode, and discrete electrode-position labeling tied to a first band length scale.
