Abstract: A hearing protection system including a detection subsystem configured to determine bone conducted sound vibrations and one or more actuators placed proximate a predetermined location on the skull of a user configured to generate cancellation vibrations out of phase with the bone conducted sound vibrations to mitigate the effect of bone conducted sound vibrations on the middle and/or inner ear of a user.

Abstract: A two-stage system for oxygenating and removing carbon dioxide from a physiological fluid, including: a primary exchange module configured to receive a gas having oxygen therein and a carrier fluid having carbon dioxide therein. The primary exchange module is configured to transfer oxygen from the gas to the carrier fluid and transfer carbon dioxide from the carrier fluid to the gas to create an oxygen loaded carrier fluid and a carbon dioxide load gas. A secondary exchange module is configured to receive the oxygen loaded carrier fluid and a physiological fluid having the carbon dioxide therein. The secondary exchange module is configured to transfer the oxygen from the oxygen loaded carrier fluid to the physiological fluid and transfer carbon dioxide from the physiological fluid to the carrier fluid to create an oxygen loaded physiological fluid.

Abstract: The present invention generally relates to methods for identifying nucleic acid ligands of a target molecule. In certain embodiments, the invention provides methods for identifying a nucleic acid ligand of a target molecule from a candidate mixture of nucleic acids, including contacting at least one target molecule with a candidate mixture of nucleic acids, in which the nucleic acids have different affinities for the target molecule, and separating in a single step nucleic acids that bind the target molecule with greatest affinity from nucleic acids that bind the target molecule with a lesser affinity and nucleic acids that do not bind the target molecule, thereby identifying the nucleic acid ligand of the target molecule.

Abstract: A patient warming appliqué typically includes a cover layer, a tape layer for releasably securing the appliqué to the patient's skin and an array of encapsulated cells. The encapsulated cells include a chemical heating mechanism beneath the cover layer and a phase change gel sheet between the chemical heating mechanism and the tape layer. The phase change gel sheet is configured to melt and flow when the chemical heating mechanism is activated. The preferred appliqué further includes zones of weakness between the spaced cells allowing the individual cells or a subset of cells to be removed from the appliqué.
