Cutaneous Electrode Positioning, Jeffrey Hargrove, Susan R. Briggs
Cutaneous Electrode Positioning, Jeffrey Hargrove, Susan R. Briggs
Mechanical Engineering Patents
A device and method for positioning a cutaneous electrode for delivery of electrical stimulation to a subject's head. A harness is worn on a subject's head with a first band of the harness worn in a closed loop around the subject's head and around a desired contact location on the subject's head. A tensioning strap of the harness is worn across the desired contact location and connected at spaced-apart attachment locations of the strap to spaced-apart attachment locations of the harness such that an electrode disposed over the desired contact location on the subject's head is held in place by …

Mechanical Engineering Patents
A computing device-controlled system is described for the generation of amplitude-modulated pulse-width modulation (AMPWM) signals for use in treating neurological dysfunction via cranial neurostimulation, where the AMPWM signal is specifically designed to minimize the electrical impedance of the tissues of the head. A low-frequency carrier signal is determined for the AMPWM signal by measuring EEG activity at a reference site or sites, generally corresponding with the location of suspected brain dysfunction. Carrier signal frequency is variably related to critical frequency components of the EEG power spectral density, determined from statistical analysis of amplitudes and variability, and dynamically changed as a …
