20080268764 | METHOD AND APPARATUS FOR A LOW IMPEDANCE ANTI-RECIRCULATION AIR MOVING INLET DEVICE - An inlet recirculation apparatus for an air moving device includes a housing defined by a wall extending from a base. The base includes an aperture therethrough receptive to alignment with an inlet of the air moving device. A plurality of flaps each pivotally extends radially outwardly from a center pivot to another corresponding pivot disposed around a perimeter of the wall. The center pivot is coaxial with a center of the aperture. Each flap moves to an open position due to air pressure from the air moving device causing air to flow into the inlet wherein each flap pivotally rotates about the center pivot and corresponding pivot at the wall, and moves to a closed position when air pressure from the air moving device ceases wherein a space between contiguous flaps is eliminated when each flap pivotally rotates to the closed position about the center pivot and corresponding pivot at the wall to prevent reverse airflow through the air moving device. | 10-30-2008 |
20120303339 | COMPUTATIONAL FLUID DYNAMICS MODELING OF A BOUNDED DOMAIN - A method for hybrid computational fluid dynamics (CFD) approach for modeling a bounded domain, such as a data center, is disclosed. The CFD modeling approach divides the bounded domain into one or more viscous regions and one or more inviscid regions, and then performs a viscous domain solve for the viscous region(s) using a computational fluid dynamics model with turbulence equations (i.e., a turbulence model), and performs inviscid domain solve for the inviscid region(s) using a set of inviscid equations (or potential flow equations). After solving for the different regions, results of the viscous domain solve and the inviscid domain solve are provided as a model of the bounded domain. | 11-29-2012 |

20130277012 | APPARATUS TO COOL A COMPUTING DEVICE - An apparatus to cool a computing device is provided and includes a structure. The structure includes a coolant moving device and a heat generating component. The structure is formed such that the coolant moving device is configured to generate a first flow of coolant into a plenum in a first direction and a second flow of coolant from the plenum in a second direction, which is transverse to the first direction, such that the coolant thermally interacts with the heat generating component. The structure further includes a plate interposed between the plenum and the heat generating component. The plate includes aerodynamic elements disposed to extend into the plenum. | 10-24-2013 |

20150061279 | ANTI-COUNTERFEITING OPTO-THERMAL WATERMARK FOR ELECTRONICS - An anti-counterfeiting technique presents, to a test thermoreflective mark at a first temperature, a first electromagnetic wave. A first test reflective profile for the test thermoreflective mark associated with the first temperature is recorded. A second electromagnetic wave is presented to the test thermoreflective mark at a second temperature. A second test reflective profile for the test thermoreflective mark associated with the second temperature is recorded. The first test reflective profile is compared with a first control reflective profile that is associated with a genuine thermoreflective mark. The second test reflective profile is compared with a second control reflective profile that is associated with the genuine thermoreflective mark. | 03-05-2015 |
