Abstract: Systems and methods are described for diagnosing, assessing, and quantifying sedative effects in a subject. The systems and methods described herein are non-invasive and based on the detection, measurement, and analysis of involuntary micromotions and/or fixational eye movements with respect to a subject's eyes, pupils, and head. Determinations as to sedation are based, in part, on divergences between measurements associated with the subject and predefined ranges, threshold values, and/or measurements contained in one or more individualized or population datasets. The described systems and methods are not reliant on the cooperation of the subject and, as a result, do not interfere with the subject's ongoing activities. The systems and methods can also be continuously deployed over any period of interest, and the results can be predictive in nature as opposed to reactionary.

Abstract: Systems and methods are described for diagnosing, assessing, and quantifying brain injuries, traumas, or concussions. The systems and methods described herein are non-invasive and based on the detection, measurement, and analysis of involuntary micromotions and/or fixational eye movements with respect to an individual's eyes, pupils, and head. Determinations as to brain injury are based, in part, on divergences between measurements associated with the subject and measurements contained in one or more datasets. The described systems and methods are accessible to subjects regardless of geographic location or access to medical professionals, and are not reliant on the cooperation of the subject such that the systems and methods described here are still effective when the subject is non-responsive.

Abstract: An apparatus for performing collision resolution in a digital control channel which includes at least two antennas for receiving interfering signals, wherein each of the signals is associated with a network user, and a processor for processing the signals received by the antennas. The processor performs blind channel estimate calculations on the interfering signals to obtain channel information and to obtain a second signal. The second signal is selected for processing by a communication network.
