  • Publication number: 20150196386
    Abstract: A bearing component 2 for a joint replacement prosthesis comprises a first bearing element 4; a second bearing element 6, and a linking element 8, operatively connecting the first and second bearing elements 4, 6 and permitting relative motion there between. The flexible linking element 8 prevents dislocation of mobile bearings in a total knee replacement prosthesis. The invention also relates to a bridging element which retains the linking element 8 with some play, which acts as a ligament support 2051, and which causes a deflection of the line of action of a ligament 1018. A joint replacement prosthesis is also disclosed comprising a biasing element 1140 or a tensioning element 1220 operatively coupled to the artificial ligament 1018. The biasing element 1140 or tensioning element 1220 may be housed in the stem of a tibia tray 1006.

  • Patent number: 9063842
    Abstract: A system and method for enforcing quotas in a data storage system. In one embodiment, a method includes the operations of receiving a first request that defines a storage quota for a pool of virtual tapes that is allocated to a user entity; defining the storage quota for the pool of virtual tapes according to the request, wherein the defined storage quota limits a quantity of data that the user entity can store in physical storage of the storage system; receiving a second request from the user entity to write data to the virtual tape of the pool of virtual tapes; and returning a first status that indicates the data to be written from the second request cannot be written and failing the second request where a quantity of the data from the user entity's second request exceeds the defined storage quota.

  • Patent number: 9054632
    Abstract: Characteristics of partially assembled photovoltaic modules can be determined using electrical connection apparatuses and methods. By providing deformable electrical contacts against a partially assembled module on an assembly line, an electrical bias can be applied to the module before the module is completely assembled. An electrical connection apparatus for a photovoltaic module may include a first contact configured to engage a first lead on the photovoltaic module, a second contact configured to engage a second lead on the photovoltaic module, and an electrical power source configured to apply an electrical bias between the first contact and the second contact.

  • Patent number: 9009742
    Abstract: According to one embodiment, a virtual tape library (VTL) receives a plurality of small computer system interface (SCSI) data objects, and translates the SCSI data objects into a first set of one or more remote procedure call (RPC) data objects having a first size, wherein the first size of the first RPC data set is based on a current limit maintained by the VTL. The VTL writes the first RPC data set and a first RPC commit request to a file system. The VTL receives a first RPC status corresponding to the first RPC commit from the file system, and determines a first latency time between writing the first RPC commit and receiving the first RPC status. The VTL updates the current limit based on the first latency time in order to optimize a second latency time between a second RPC commit request and a corresponding second RPC status.

  • Patent number: 8933510
    Abstract: An integrated circuit containing a MOS transistor and a DEMOS transistor of a same polarity may be formed by implanting dopants of a same conductivity type as source/drain regions of the MOS transistor and the DEMOS transistor through a gate of the MOS transistor and through a gate of the DEMOS transistor. The implanted dopants are blocked from a drain-side edge of the DEMOS transistor gate. The implanted dopants form a drain enhancement region under the DEMOS transistor gate in a drift region of an extended drain of the DEMOS transistor.
