  • Patent number: 8211181
    Abstract: An artificial knee joint that includes a femoral component with a specially shaped bearing surface and a tibial component, whose surface interacts with the femoral surfaces. The interaction provides for the required motion and stability characteristics. The interaction between the femoral and tibial surfaces is such that as the knee is flexed to maximum, the femoral component moves posteriorly on the tibial surface, by an amount similar to that in the anatomic knee. This is accomplished primarily by the depth and width of the femoral trochlea diminishing as the femoral component is flexed from zero to maximum, together with a ramp on the center of the tibial surface. The opposite motion, roll forward of the femur from a fully flexed to a more extended position, is accomplished by varying the outward radii of the lateral and medial femoral bearing surfaces, together with a ramp on the postero-lateral and postero-medial regions of the tibial surfaces.

  • Patent number: 8010951
    Abstract: A fault-tolerant method of bottom-up editing whereby simultaneous display of the GUI view and source code view are available, and wherein real-time bottom-up editing is provided. In accordance with a preferred embodiment of the present invention, changes to the source code are isolated, first by isolating and analyzing source code according to groupings associated with the structure of the language used for the source code and then isolating and analyzing individual lines of source code within these groupings. If there are no errors in a particular grouping of source code, the changes in the grouping are automatically applied to the GUI. If errors are found in a grouping, the grouping is further analyzed to determine which lines contain the error. Semantic and syntactic errors are thereby isolated and, where found, are ignored. However, correct lines of the source code are also identified and thereby applied to the GUI for interpretation and display.

  • Patent number: 7962862
    Abstract: A method and software tool for performing an operation on a graphic object in a display of overlapping graphic objects in a data processing system are provided. The method comprises the steps of detecting the position of a pointer on the display; displaying to a user an indication of potential target objects of the operation which coincide with the pointer position; detecting a selection of one of the indicated potential target objects as the target object; and performing the operation on the selected object. In the case where the target object is not the outermost layer of the graphic objects on the display, the method may also comprise temporarily making the selected target object visible during performance of the operation on the target object by making the overlying objects transparent.

  • Patent number: 7865870
    Abstract: The invention is directed to a method which derives from metadata definitions the allowable values for a method argument, where the allowable values are a subset or a restricted set of values from a defined range of values for that type of method argument. The subset of allowable values is then converted into a fragment of source code that can be used to initialize the argument variable with one of the allowable values when the method is invoked. The fragment of source code is inserted into the source code for that method argument using an editor tool. A system for implementing the method may comprise an integrated development environment (IDE) program.

  • Patent number: 7861516
    Abstract: An exhaust system for a vehicular lean-burn internal combustion engine includes a NOx reduction catalyst, a source reductant, means (20) for contacting the catalyst with the reductant, means for sensing the temperature of the exhaust gas and/or the catalyst bed and means, when in use, for controlling reductant addition. The reductant addition control means supplies an amount of reductant to the catalyst at a rate corresponding to a measured temperature value of the exhaust gas and/or catalyst bed, which temperature value has been pre-determined to correlate, in use, with an amount of NOx in the exhaust gas.

  • Patent number: 7376905
    Abstract: An improvement to the known method/system for distribution of elements displayed in GUI windows and similar processing environments is disclosed. A visible, moveable, and size-adjustable bounding box is provided. The user can specify any size for the bounding box and locate the bounding box anywhere in the window. In this manner, the user adjusts the size and location of the bounding box as desired, rather than having to manipulate the various elements to try to define the desired spacing and location.
