  • Publication number: 20200038192
    Abstract: An orthopedic assembly includes a tibial prosthesis that includes a body that defines an anterior side and a posterior side. The body further includes a recess in the anterior side of the joint prosthesis and a plurality of openings that extend through the body from the anterior side to the posterior side thereof. At least a first and second opening of the openings are positioned at respective lateral and medial sides of a longitudinal axis of the tibial prosthesis. A modular insert is positioned within the recess of the body such that at least a portion of the modular insert is positioned between the openings of the body. The modular insert is formed separately from the tibial prosthesis and has a porous outer surface to promote tissue ingrowth.

  • Patent number: 10501344
    Abstract: A method reuses produced water resulting from a fossil fuel extraction operation. The method includes providing the produced water as an input to an electrodialysis system. The method also includes running the electrodialysis system to produce a diluate and a concentrate. The diluate is contaminated so as to have a conductivity of no less than 0.1 Siemens/meter. The method also includes reformulating the diluate to produce fossil fuel extraction fluid. The method also includes using the produced fossil fuel extraction fluid in the fossil fuel extraction operation. An electrodialysis system includes first and second stacks. The electrodialysis system also includes first and second voltage sources, coupled to the first and second stacks, so as to apply a first voltage to the first stack lower by at least about 10% than a second voltage to the second stack.

  • Publication number: 20170091810
    Abstract: A method, system, and computer program product for classifying, weighting, and quantifying audience responses to stimulation. A method commences by forming a predictive model comprising parameters derived from response data records taken from the Internet and stimulus data records takers item the performance or execution of a media plan. A database of user configurations is consulted to access brand engagement event weighting parameters. The brand engagement event weighting parameters are combined with simulation data to generate weighted touchpoint contribution values that can in turn be used to predict future responses front the audience or a similar future audience. The weighted touchpoint contribution values are used to calculate audience engagement scores. A selected set of audience engagement scores are used to determine spending in a media plan.

  • Publication number: 20140277190
    Abstract: A bone screw apparatus is provided for threaded engagement with a bone and, optionally, a medical device such as a bone plate. The bone screw has a shaft having a first end, a second end, and a first thread having a first pitch. The screw further includes a head having a proximal end, a distal end adjacent the shaft first end, and a second thread having a second pitch. The second thread has a variable pitch that increases in a proximal direction, but never exceeds the magnitude of any portion of the first pitch. Upon threaded engagement of the head with bone or a medical device, a compression force is generated which continuously decreases as the screw is further inserted.

  • Patent number: 8491587
    Abstract: An orthopaedic instrumentation having an intermediate piece that has an opening for receiving an intramedullary reference. The intermediate piece such as a tibial template or a cutting guide is located on the resected tibia or femur in a manner that it optimally covers the resected surface of the tibia or the femur. A bushing guide is provided for mounting on the intermediate piece. The bushing guide has a circular opening. An offset bushing is rotatably mounted in the opening in the bushing guide. A trigger flange is slidably mounted on the offset bushing. The trigger flange can slide back and forth relative to the offset bushing. An indicia is formed on the upper surface of trigger flange. The indicia when aligned with one of the indicia on the offset bushing body measures the offset of center of a bore in the trigger flange from center of the offset bushing. The offset bushing can rotate around its longitudinal axis in the opening in the bushing guide.
