Abstract: A system for use in performing ocular examinations, such as convergence and accommodation useful in diagnosing traumatic brain injury (including concussion), includes an assessment device. The assessment device includes a portable carrier having a visual target and a distance measurement component. The system may further include a communications channel and a companion device. The distance measurement component communicates via the communication channel with the companion device. The companion device stores one or more distances measured by the distance measurement component.

Abstract: One or more techniques and/or systems are disclosed for use with a syringe or pipette that may provide improved dispensing of fluids from the syringe or pipette. For example, typical syringes or pipettes can draw in a desired volume of fluid, and subsequently dispense the same volume. As described herein, a device can be configured to draw in a first volume and subsequently dispense the first volume and a second volume of fluid, such that portions of the fluid, such as liquids, that may be retained in the syringe or pipette can be displaces by the second volume.

Abstract: Methods and systems for assessing brain activity and collecting information related to a subject's condition and brain electrical activity are provided. The methods and systems include collecting and transferring data related to the neurological state of a subject. The systems and methods further include performing a first assessment of the collected data using an assessment device and performing a second assessment of the collected data using a computer. The methods further include comparing the first assessment and the second assessment and recording whether the first assessment and second assessment are consistent.

Abstract: One or more techniques and/or systems are disclosed for an apparatus for use with a syringe or pipette. A chamber body can comprise a first chamber, a second chamber, and a fluid port. A first fluid seal can be disposed in the first chamber, and a second fluid seal can be disposed in the second chamber. The chamber body can comprise a first volume which is defined by a first chamber wall, the first seal, and the second seal, when the first seal and second seal are disposed in a first position. The first volume can also be defined by a sum of: a second volume defined by at least a second chamber wall, the first seal, the second seal; and a third volume comprising fluid displaced at the fluid port, when the first seal and second seal are disposed in a second position.

Abstract: A device and method for assessment of traumatic brain injury (TBI) is described. The device is configured to acquire brain electrical signals from a patient's forehead using one or more neurological electrodes. The acquired brain electrical activity data is subjected to artifact rejection and feature extraction, and a subset of features are then combined in at least one classifier function. The classifier functions statistically place a patient in one of four categories related to the extent of brain dysfunction: 1) normal brain electrical activity; 2) abnormal brain electrical activity consistent with non-structural injury with less severe manifestations of functional brain injury; 3) abnormal brain electrical activity consistent with non-structural injury with more severe manifestations of functional brain injury; and 4) abnormal brain electrical activity consistent with structural brain injury.
