Abstract: A system for measuring and controlling foot temperature. The system comprises a heating or cooling device including one or more sealed fluidic pathways having a cooling or heating fluid therein and disposed in or on an article of footwear or a sock. A pumping device coupled to the heating or cooling device is configured to circulate the fluid in the one or more sealed fluidic pathways. A heat exchanger coupled to the heating or cooling device is configured to remove or add heat from or to the fluid in the one or more sealed fluidic pathways. A controller coupled to the pumping device and the heat exchanger is configured to control the pumping device and the heat exchanger to cool or heat a foot located inside the article of footwear or the sock.

Abstract: An apparatus for exchanging small molecules with a fluid includes a small-molecule conduit for providing a first fluid having a first type of small molecule, a target fluid conduit for providing a target fluid having a second type of small molecule therein, and a carrier fluid conduit for providing a carrier fluid that is configured (i) to receive at least some of the first type of small molecule from the first fluid and transfer at least some of the first type of small molecule to the target fluid and (ii) to receive at least some of the second type of small molecule from the target fluid and transfer at least some of the second type of small molecule to the first fluid. The apparatus further includes an exchange module having an exchange chamber in fluid communication with the small-molecule conduit, the target fluid conduit and the carrier fluid conduit.

Abstract: A system for suppressing vestibular activity of a human subject includes an electronics module configured to generate one or more electrical stimulation signals. A plurality of electrodes each placed proximate a predetermined location on a head of a human subject is configured to deliver the one or more electrical stimulation signals to the predetermined location to suppress vestibular activity of the human subject.

Abstract: A system which includes a first sensor placed proximate to a perfusion field of an artery receiving blood which emanates from the cranial cavity is configured to monitor pulsations of the artery receiving blood which emanates from the cranial cavity artery. A second sensor placed proximate to a perfusion field of an artery which does not receive blood emanating from the cranial cavity configured to monitor pulsations of the artery which does not receive blood emanating from the cranial cavity. A third sensor configured to monitor pulsations of a distal artery. A processing system responsive to signals from the first, second, and third sensors is configured to determine intracranial pressure.

Abstract: An intervertebral support insertion tool includes a tube having a distal open end for insertion in a patient proximate vertebra and a proximal open end. A shaft is received in the tube proximal open end and has a distal intervertebral support interface for engaging an intervertebral support loaded into the tube. A housing supports the tube and shaft with a first drive mechanism such a linear actuator advances the shaft in the tube. A second drive mechanism such as a rotational drive rotates the shaft. In this way the shaft advances and rotates the intervertebral support to position and deploy it between adjacent vertebrae.

Abstract: A system which includes a first sensor placed proximate to a perfusion field of an artery receiving blood which emanates from the cranial cavity is configured to monitor pulsations of the artery receiving blood which emanates from the cranial cavity artery. A second sensor placed proximate to a perfusion field of an artery which does not receive blood emanating from the cranial cavity and approximately the same distance from the heart as the first sensor configured to monitor pulsations of the artery which does not receive blood emanating from the cranial cavity. A third sensor placed distally from a heart is configured to monitor pulsations of a distal artery. A processing system responsive to signals from the first, second, and third sensors is configured to determine intracranial pressure.
