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: A physiologic condition sensor comprises a sensor body including an optical assembly housed in a sensor housing. The optical assembly is configured to include a head portion, a tail portion, and an intermediate portion connecting the head portion and tail portion. The head and tail portions are wider than the intermediate portion to prevent longitudinal deformation of the sensor housing around the optical assembly.

Abstract: An electrocardiogram (ECG) electrode patch for attachment to a neonatal or infant patient. The ECG electrode patch includes a plurality of at least three electrodes coupled to a substrate. The plurality of at least three electrodes includes at least one electrode capable of measuring the electrical activity of the right side of the patient's heart. A plurality of electrical conductors are coupled to the plurality of electrodes and to the substrate.

Abstract: A method and apparatus for assessing tissue perfusion of a patient. The apparatus includes a probe for contacting the mucosa tissue in the upper respiratory/digestive tract of the patient, and a sensor coupled to the probe for directly detecting a pH measurement of the mucosa tissue and for generating an electrical signal in response to the detected pH measurement.

Abstract: A flexible multiple electrode assembly includes at least one fixed electrode; at least one extendible electrode; and electrically conductive interconnections coupling the at least one fixed electrode and the at least one extendible electrode to a common connector. The at least one extendible electrode is adapted to be physically separable from the at least one fixed electrode while remaining electrically coupled to the common connector. In one embodiment, an array of fixed and extendible electrodes is configured for the acquisition of electrical pulses from a heart for transmission to an electrocardiograph (EKG or ECG) device.
