  • Patent number: 11960202
    Abstract: An EUV microscope device utilizing a source of a beam of EUV light. The light is sent to a collector which produces a first focused EUV beam. A monochromator receives the first focused EUV beam and produces a second EUV beam that is passed to an illumination module. The output of the illumination module is passed to a mask. The reflected beam from the mask is sent to a zone plate and a detector to produce an image.

  • Patent number: 10575971
    Abstract: Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities: (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.

  • Patent number: 9730810
    Abstract: Systems, devices, and methods are provided for measuring forces in the space of a knee during surgery. Such forces can be caused by tension in the ligaments of the knee. A femoral member is engaged with a distal femur. While the knee is flexed, partially extended, or fully extended, a force sensor and a gauge shim can be placed in the gap between the femoral member and the tibial plateau to measure the forces therebetween. The force sensor provides an accurate and quantifiable measurement of force, making knee replacement surgery and ligament tension balancing more accurate, standardized and repeatable. The force sensor comprises an elongate housing which comprises a thin force sensing distal portion and a proximal handle portion.

  • Patent number: 8348957
    Abstract: An instrument assembly for placing a guide pin in a femoral neck of a patient with reference to a medullary guide wire for use in resurfacing a femoral head. The assembly comprises a femoral neck clamp configured to define a femoral neck center. A pin guide attaches to the femoral neck clamp. A pin guide portion of the pin guide is configured to define a pin guide path passing through the neck center. The pin guide portion is linked to pin guide engagement portion of an adjustable goniometer. The goniometer maintains a specific angle between the pin guide engagement portion and the medullary guide wire, and in turn maintains the pin guide path at the specific angle.
