3 Independent Claims

1. A system for bi-hemispheric brain wave measurements, comprising: a first device configured to be worn in or at a first ear of a person subject to the measurements and comprising a first and a second measurement electrode adapted for measuring a first brain wave signal, a first data acquisition component coupled to said measurement electrodes, said first data acquisition component comprising at least one amplifier and configured to provide first digital data representing said first brain wave signal, a first brain wave signal analyzer configured for analyzing at least said first digital data, and first wireless link component operable to establish a wireless connection with a second wireless link component; and a second device configured to be worn in or at a second ear of said person and comprising a third and a fourth measurement electrode adapted for measuring a second brain wave signal, a second data acquisition component coupled to said measurement electrodes, said second data acquisition component comprising at least one amplifier and configured to provide second digital data representing said second brain wave signal, and said second wireless link component; wherein said first brain wave signal analyzer is configured to combine a first characteristic feature and second characteristic feature during the course of its analysis, wherein the first characteristic feature is derived unilaterally from the first device of the system and the second characteristic feature is derived unilaterally from the second device of the system, wherein the system is configured for detection of at least one of impending hypoglycemia or epileptic seizures based said analysis by said first brain wave signal analyzer, and redundancy from having a combination of unilateral signal features is provided to improve robustness of said system.
20. A method for performing bi-hemispherical brain wave analysis, comprising the steps of: measuring a first brain wave at a first device in, or in the vicinity of, a first ear of a person subject to the analysis; measuring a second brain wave at a second device in, or in the vicinity of, a second ear of said person; wirelessly transmitting data representing at least one of said first and said second measured brain wave using a wireless connection between said first device and said second device; and analyzing data representing said first and said second measured brain wave, hereby providing a bi-hemispherical brain wave analysis; wherein said analyzing step comprises combining a first characteristic feature and second characteristic feature, wherein the first characteristic feature is derived unilaterally from the first device and the second characteristic feature is derived unilaterally from the second device, wherein the method comprises detection of at least one of impending hypoglycemia or epileptic seizures based on results of said analyzing, and redundancy from having a combination of unilateral signal features is provided to improve robustness of said method.
23. A method for performing bi-hemispherical brain wave analysis, comprising the steps of: providing from a first device an audio stimulation of a first ear of a person subject to an analysis; measuring a brain wave at a second device in, or in the vicinity of, a second ear of said person; exchanging data over a wireless connection between said first and second devices in order to synchronize in time said first and said second device; analyzing said brain wave measurement with respect to the audio stimulation; wherein said analyzing step comprises combining a first characteristic feature and second characteristic feature, wherein the first characteristic feature is derived unilaterally from the first device and the second characteristic feature is derived unilaterally from the second device, wherein the method comprises detection of at least one of impending hypoglycemia and epileptic seizures based on said analyzing, and redundancy from having a combination of unilateral signal features is provided to improve robustness of said detection.
