The electrical properties of the subject are fit to a model and a specific range of a set of characteristic frequencies of each tissue is then calculated. Each tissue is finally characterized as cancerous or non-cancerous if the specific range of the set of characteristic frequencies inside or outside, respectively, a pre-determined spread of characteristic frequencies.

Abstract: A system and method for determining a subject's attentional response to a stimulus. The method includes measuring microsaccadic eye movement dynamics of the subject, detecting whether a microsaccadic signature (a suppression in microsaccadic rate) is present in the measured microsaccadic eye movement relative to a time of the stimulus, and correlating the subject's attentional response to the stimulus based on the detection. The method further includes determining that the stimulus was sensed if the microsaccadic signature is present and determining that the stimulus was not sensed if the microsaccadic signature is absent.

Abstract: A method and apparatus for quantifying differences in human sensorimotor performance useful for diagnosing, assessing, and/or detecting brain injury and/or a neurological disorder, or identifying exceptional performance in a subject. In a task a subject's limb movement is restricted to a limited workspace and an object moves towards the limb. The objective of the task is for the subject to contact the object with the limb within a set time period. During the task a perturbation directed to the object and/or limb, or other feature of the environment, may occur on some trials, requiring a rapid motor correction in order to contact the object, or the subject may receive an alternative instruction on whether to interact with the object. Position data and/or motion data and/or kinetic data of the limb or portions thereof with respect to a presented object are obtained, and a data set is acquired for a plurality of trials.

Abstract: A funnel-shaped extension attachment is provided for a blood collection device. The attachment provides a larger area for collecting a fingertip blood sample from a patient than the collection device itself would otherwise provide. The funnel is preferably easily removable from the collection device after the blood sample is taken. Optional trenches running down one or more corners of the attachment may be used to encourage pulling blood drops from the finger tip through capillary action. A tube may also provide another location to encourage pulling blood drops from the finger tip through capillary action. The funnel attachment may be mated with the collection device at a point of manufacture, or separately shipped and installed over the collection device at a point of use.
