Abstract: Systems, methods and computer program products are described herein that can be used to help achieve a safe rollout of software in a production datacenter environment. In accordance with certain embodiments, cloud services requests from certain users of a cloud services system (e.g., users that are authorized to receive cloud services via computing devices running test versions of infrastructure software) are dynamically matched to clusters (groups of commonly-managed computing devices called nodes) that are capable of providing the requested services on nodes running test versions of infrastructure software. Within such clusters, the requested services are provided to the users on a subset of cluster nodes that run a test version of an infrastructure software component, while the remaining cluster nodes are not running the particular test version.

Abstract: A method and apparatus for vibro-treating an object. The method includes the steps of controlling a relative displacement between a vibro-treating media and a surface area of the object to provide a vibro-treating effect; and, controlling movement of the object relative to a surface of the vibro-treating media while controlling relative displacement between the vibro-treating media and the surface area of the object, according to one or more pre-determined conditions, to provide a substantially even vibro-treating condition over the surface area of the object.

Abstract: A prosthesis having an oxidized zirconium surface and a porous textured surface is described. A major advantage of the prosthesis is increased service life. Additionally, a process of manufacturing the prosthesis is described.

Abstract: A textured surface and oxidation layer coating on a metallic material is accomplished through the chemical and/or electrochemical etching of the surface to modify the surface texture and an in-situ oxidation procedure. The surface is useful for the fabrication of prosthetic devices, particularly medical implants, due to the corrosion and wear resistance imparted by the oxidation layer and the ability to enhance grafting of the implant onto bone imparted by the surface texture.

Abstract: A hanger bar assembly for supporting an outlet box between spaced apart support elements including a first channel member being longitudinally slidingly engagable with a second channel member forming a longitudinally adjustable support bar. The first channel member has a plurality of longitudinally extending grooves and the second channel member having a plurality of longitudinally extending rails slidingly received in the grooves such that lateral movement between the first and second channel members is resisted. A clamping device is provided for urging the first and second channel members into respective forced engagement thereby restricting movement between the first and second channel members. A securement device attached to the support bar for securing the support bar to the spaced support elements is further provided. The first and second channel members have apertures formed therein to accommodate fasteners for securing end plates to the support.

Abstract: An orthopedic implant with a diffusion-hardened surface on non-load bearing areas of the implant for interaction with non-load bearing surfaces of a polymeric bio-compatible material, such as UHMWPE (ultra-high molecular weight polyethylene). The orthopedic implant is a mobile-bearing knee prosthetic and system where a coating of oxidized zirconium is formed on the post of the tibial tray of the prosthetic for interaction with an opening of a polymeric tibial insert. The diffusion-hardened surface of the orthopedic implant provides a strengthened post and reduction in wear in the opening of the polymeric insert.

Abstract: A prosthetic device having at least part of its surface comprising a diffusion-hardened, in-situ formed oxidation or nitridation layer and with at least another part of its surface comprising a coating of bioceramic, preferably hydroxyapatite. The bone in-growth and on-growth promoting bioceramic further works synergistically with the diffusion-hardened surface in realizing a longer service life prosthetic.

Abstract: An orthopedic implant with a diffusion-hardened surface on non-load bearing areas of the implant for interaction with non-load bearing surfaces of a polymeric bio-compatible material, such as UHMWPE. The orthopedic implant is a posterior stabilized knee prosthetic and system where a coating of oxidized zirconium is formed in the cam of the femoral prosthetic for interaction with the central post of a polymeric tibial insert. The diffusion-hardened surface of the orthopedic implant provides a strengthened cam and reduction in wear in the central post of the polymeric tibial insert.
