A resistance device (100) includes a field-effect transistor (TN) and a voltage applying circuit (1). The voltage applying circuit (1) applies a control voltage (Vgs) between the gate and source of the field-effect transistor (TN) according to a temperature (T) to control a resistance value (R) between the drain and source of the field-effect transistor (TN). The control voltage (Vgs) is a voltage obtained by adding a correction voltage (Vc) to a reference voltage (Vgs0). The correction voltage (Vc) depends on the temperature (T) and is set to be zero at a first temperature (T1).

Presented herein are techniques for assessing one or more outcomes associated with implantation of one or more electrodes into the inner ear of a recipient.

This disclosure relates to using stereo-thermo-lesioning (STL) to create lesions at one or more locations in the patient's nervous system at the patient's bedside without general anesthesia. A method that uses STL to treat a patient's neurological condition includes: using a plurality of stereotactically-implanted thermo-coupled multi-contact electrodes to record conduction data within a predetermined theoretical zone of activity within the patient's neurological tissue; detecting abnormal neurological activity of a neurological condition within the conduction data and localize a portion of the predetermined theoretical zone of activity that is responsible for a primary organization of the abnormal neurological activity; creating a lesion at the portion of the predetermined theoretical zone of activity that is responsible for a primary organization of the abnormal neurological activity using at least one contact of the plurality of thermo-coupled multi-contact electrodes.

Methods and systems monitor and assess brain bioimpedance through the use of an ocular window that assesses dynamic changes in cerebral blood volume (CBV). That ocular window is implemented through an ocular bioimpedance device that, in a non-invasive manner, measures numerous different brain health indicators using the bioimpedance measurements collected through the regions around the eyes. The ocular bioimpedance device may be goggles with localized measurement electrodes that include cathodes and anodes.

A quantum cardiac electrophysiology device comprising an array of consumable half-ferromagnetic active electrodes connected to an array of semiconductor of half-ferromagnetic selector switches over an array of half-ferromagnetic resistors to a neutral charges out of the heart, by casting and/or inking the arrhythmic substrate of an arrhythmia by the electrophysiology quantum entan- glement of said arrhythmic substrate.

A method and apparatus for treating bone or other infection in a patient to minimize the number of limb amputations which employs a unique, three-dimensional software-controlled electronic phased array amplifier system using arbitrary waveforms that dynamically and proportionally steer electrical currents by using two or more current vector paths, sequentially or simultaneously, through a defined infected area containing electrically-conductive ionic solutions so as to obtain 100% treatment using low or high voltage, low current that delivers electrical stimulation (ES) using a low DC current through and or around the defined infection treatment area. The minimally invasive treatment of the infection requires no radiation or chemotherapy that could be harmful to the patient.
