20100004517 | NON-INVASIVE METHOD AND APPARATUS FOR DETERMINING A PHYSIOLOGICAL PARAMETER - The present invention relates to an apparatus and method for the non-invasive analysis of physiological attributes, such as heart rate, blood pressure, cardiac output, respiratory response, body composition, and blood chemistry analytes including glucose, lactate, hemoglobin, and oxygen saturation. Using a combination of multi-functioning disparate sensors, such as optical and electrical, improvements are made over existing physiological measurement devices and techniques. The special configuration of one or more multi-functional sensors is used to non-invasively measure multi-wavelength optical plus one or more of ECG, Bio-impedance, and RF-impedance spectroscopic data. This information is used to develop self-consistent, non-linear algorithm in order to derive the physiological attributes while compensating for various forms of interfering effects including motion artifacts, sensor attachment variability, device component variability, subject physical and physiology variability, and various interfering physiological attributes. | 01-07-2010 |
20100016703 | BIO-ELECTRODE POSSESSING A HYDROPHILIC SKIN-CONTACTING LAYER AND AN ELECTROLYTE SUBSTANCE - A bio-electrode for conveying electrical signals to, or from a body is constructed with two components, a pre-laminated member and a re-usable electrode assembly. The pre-laminated member comprises a first substrate layer and a second electrolyte-containing layer. The substrate contacts the body and is constructed of a material that is biocompatible, hydrophilic and inherently electrically semi-conductive or conductive. The electrolyte-containing layer, which does not contact the body, is composed of an adhesive, electrolytic hydrogel. Small amounts of moisture and electrolytes from the hydrogel diffuse into the substrate thereby reducing and stabilizing the substrate's electrical resistance. The pre-laminated member can be used with existing re-usable electrode assemblies. | 01-21-2010 |
20140172041 | NEUROSTIMULATION SYSTEM, DEVICE, AND METHOD - A device for cranial nerve stimulation of an individual is disclosed, having a signal driver unit for producing a current; an intraoral stimulation board having at least one primary electrode, and at least one secondary electrode positioned on the individual for communicating a current through the individual, wherein current can flow between the intraoral stimulation board and the secondary electrode. The device may be used to treat a number of ailments. In one embodiment, the device provides input representing two planes of movement, or is used as a gaming controller. A method of using an electrical stimulation system is also disclosed, comprising the steps of: a) positioning the intraoral stimulation board within the individual's mouth; b) connecting the secondary electrode to the individual; c) operating the signal driver unit for a predetermined time to provide a current flow between the intraoral stimulation board and the secondary electrode. | 06-19-2014 |
20150025352 | METHOD AND DEVICE FOR DETERMINING BRAIN AND SCALP STATE - A method for determining brain state has the steps of attaching at least 2 first electrodes to the scalp of a subject at a separation, transmitting an electrical current between the at least 2 first electrodes, and measuring a first impedance between the at least 2 first electrodes to provide a resulting impedance. One embodiment has the further step of comparing the resulting impedance to pre-stored impedance measurements of the scalp to determine normal or pathological state. A further embodiment has the steps of attaching 2 first electrodes to the scalp of a subject at a separation and 2 second electrodes, transmitting a current between the first electrodes and measuring a first impedance between the second electrodes to provide a resulting impedance. The electrodes may be driven shield electrodes, and the method may further include comparing impedance measurements to pre-stored impedance measurements to determine normal and pathological state. | 01-22-2015 |
