| 20120071781 | ELECTRODE SYSTEM WITH IN-BAND IMPEDANCE DETECTION - An apparatus comprises a headset and a control unit in communication with each other. The headset comprises a plurality of electrodes operable to measure ERP readings. The headset is configured to be positioned on a test subject. The control unit is configured to store and administer an ERP test protocol. The control unit is also configured to administer an impedance test and process the impedance of the electrodes. The impedance testing may be performed in an in-band fashion, along the same channels used to perform the ERP testing, at the same frequency of the ERP readings, and substantially simultaneously with the ERP readings. | 03-22-2012 |
| 20100125190 | Electrode System - An electrode system comprises electrode modules, flexible connectors, and sensors. Each electrode module defines a substantially central opening and has circuitry that includes an amplifier. A conductive ring is exposed in the opening of each electrode module. The flexible connectors include flexible circuitry coupled with the circuitry of the electrode modules. Each sensor includes an electrolytic hydrogel portion that is configured to contact a test subject and outwardly extending tabs that are in communication with the hydrogel portion. The tabs are configured to contact the conductive ring of an electrode module with the sensor is inserted in the opening of the electrode module. The system may thus sense evoked response potentials (ERPs) from the test subject through the electrolytic hydrogel portions, amplify those potentials, and communicate the amplified potentials through the circuitry of the flexible connectors. A control box may initiate ERP testing and store the test results. | 05-20-2010 |
