    • The present invention relates to an artificial synovial fluid composition that mimics the tribological and biochemical properties of human, osteoarthritic synovial fluid for in vitro testing of implantable materials. The artificial synovial fluid comprises new-born calf serum or alpha-calf serum (iron-free or iron-supplemented) that contains a specific total protein concentration, specific protein constituent fractions (albumin, α-1 globulin, α-2 globulin, β-globulin, and γ-globulin), specific trace element concentrations (Ca, Mg, inorganic P, and Fe), and a specific low-molecular weight peptide concentration important for in vitro testing of implantable materials. In addition, the artificial synovial fluid contains a hyaluronic acid concentration and level of osmolality (preferably using phosphate buffered-saline solution) to mimic the thermal stability (transition mid-point temperature, enthalpy, and entropy) and pH level as measured clinically.

    • A wireless communications device has a processor coupled to a memory for reconstructing a map feature from discrete sets of map data that provide redundant labels for the map feature to thereby generate a reconstructed map feature having only a single instance of the label, wherein the memory stores a run-time label cache for caching the reconstructed map feature and the label associated with the reconstructed map feature for reuse in rendering a subsequent map that also includes the reconstructed map feature. As new map data is received for each subsequent map, for example when the map is panned, the reconstructed map feature is modified by trimming off portions of the map feature that have moved outside the area of interest and by stitching to the reconstructed map feature portions of the map feature that have moved into the area of interest.
