Abstract: A rack and system for cooling computing devices such as in a data center is disclosed. In one embodiment, the rack supports a plurality of computing devices and comprises a plurality of planar annular sector or trapezoidal shelves, each having one or more positions for holding computing devices. A number of vertical supports may hold the shelves in a vertically spaced arrangement, and an air barrier may be affixed to the rack. The air barrier may have openings for the computing devices to permit exhaust air to flow through the air barrier into a hot aisle. The rack maybe configured to be connected to other similar racks to form a vertical annular hyperboloid or a vertical hyperbolic annular paraboloid, and the computing devices may be installed to discharge exhaust at an angle relative to a centerline of the vertical annular hyperboloid or a vertical hyperbolic annular paraboloid to improve airflow.

Abstract: Systems and methods for managing airflow for cooling computing devices (e.g. in a data center) in normal and cold environments are disclosed. In one embodiment, the method comprises positioning the computing devices on a plurality of racks with air barriers to create hot and cold aisles. The computing devices may be configured in a first mode to draw in cool air the cold aisles and exhaust heated air into the hot aisles. Temperatures in the cold aisles may be periodically measured. In response to temperatures below a predetermined threshold, one or more of the cold aisles may be converted into a temporary hot aisle by adjusting ventilation openings and configuring a subset of the computing devices to temporarily draw in warm air from the temporary hot aisle.

Abstract: The present invention is directed to biocompatible polymeric powders to be used for 3D printing applications. More specifically, the 3D printing process will allow a tool less manufacturing of medical devices in particular in the implantables or regenerative space. Its flow and other processing characteristics qualifies them for the use in selective laser sintering, but also could be suitable for other powder based 3D printing technologies.

Abstract: A method may include identifying a plurality of constraints corresponding to a plurality of configuration entities comprising at least a first configuration entity and a second configuration entity. The plurality of constraints can match particular configuration values for the plurality of configuration entities. The method may further include assigning rating values to constraints that match the particular configuration values. The rating values can be based on an importance criterion corresponding to the first configuration entity and the second configuration entity respectively. The method can further include generating a configuration scoring and ranking template comprising information corresponding to the plurality of constraints and the particular configuration values and assigning the first configuration entity to a first network category and the second configuration entity to a second and different network category.

Abstract: The present invention comprises a polymer and/or polymer composite based sleeve to be fitted between an extended body, such the neck, trunnion, and/or stem of a hip implant, and a receiving body, such as a femoral head in a hip implant, that reduces wear, decreases toxic material from wear debris, enhances the mechanical connection of the extension and receiving body, reduces or eliminates impingement with receiving body, delocalize stress concentrations, and may also serve as a modifying junction between an extension and receiving body of unmatched size. The polymeric based sleeve presently disclosed comprises an inert and/or biologically favorable material which may be used in its virgin form or contain biocompatible additives. In order to best match patient and implant requirements, modifications may be made in the length, thickness, composition, as well as the presence of a taper, or lack thereof, in order to be compatible with existing devices.
