Abstract: Disclosed is both a method and apparatus for delivering cooling air to an electronics rack in a data room in an energy efficient manner. The present apparatus provides directionally delivered cooling air to an electronics rack with usage rates up to 90%. The tiles utilize angled directional vanes for delivering the cooling air. The tiles both conserve energy and increase the overall possible power usage for each cabinet. The tiles greatly increase the cooling efficiencies in the data room and conserve energy.

Abstract: A steerable sheath having an inner catheter that can slide and rotate within an outer rigid composite catheter and whereby an entire range of curvatures can be formed by the distal end of the inner catheter through sliding and/or rotating the inner catheter within the outer catheter. The inner catheter can be releasably locked within the outer catheter. Curvature indicia are provided on the inner sheath to facilitate creating a particular three-dimensional curve. Apertures are provided in the inner sheath to permit flushing the device with a single flushing source.
