Abstract: The present invention provides methods and systems for patient-specific seizure onset detection. In one embodiment, at least one EEG waveform of the patient is recorded, and at least one epoch (sample) of the waveform is extracted. The waveform sample is decomposed into one or more subband signals via a wavelet decomposition of the waveform sample, and one or more feature vectors are computed based on the subband signals. A seizure onset can then be identified based on classification of the feature vectors to a seizure or a non-seizure class by comparing the feature vectors with a decision measure previously computed for that patient. The decision measure can be derived based on reference seizure and non-seizure EEG waveforms of the patient. In another aspect, similar methodology is employed for automatic detection of alpha waves. In other aspects, the invention provides diagnostic and imaging systems that incorporate the above seizure-onset and alpha-wave detection methodology.

Abstract: The invention generally is related to preventing or inhibiting microbial infections on live tissues or in relation to the use of medical articles. In one embodiment, the invention is directed to a method for forming an antimicrobial coating on live tissue or a medical article, such as, for example, a catheter. The method includes applying to a live tissue or a surface of a medical article an aqueous or non-aqueous composition that includes at least one silane of the general formula R1nSi(OR2)4-n wherein, n is an interger of 1 or 2, R1 generally is a lower alkyl group, a C6-C8 aryl group, or a functional group, such as vinyl, acrylic, amino, mercapto, or vinyl chloride functional group, and R2 generally is a lower alkyl group. A partial condensate of a silanol of the formula R1Si(OH)3 also can be used. The composition includes one or more additional ingredients. The method also includes reacting and/or curing the silane, in the presence of the one or more ingredients, thereby forming the antimicrobial coating.
