  • Portable therapy device
    Patent number: 7175602
    Abstract: A portable medical device suitable for use in continuous passive motion (CPM) rehabilitation programs has a lightweight modular frame for ease of storage and portability. In one embodiment a proximal sling module is pivotally connected to a distal sling module with is pivotally connected to a heal plate module. Another embodiment includes a base module is pivotally connected to a proximal sling module which is pivotally connected to a distal sling module pivotally connected to a link pivotally connected to the base. The joint of a patient's limb is flexed through a range of motion by pivoting the distal sling module relative to the proximal sling module. The device is powered by a motor and worm gear directed by a controller.

  • Process for the electrophoretic deposition of defect-free metallic oxide coatings
    Patent number: 5415748
    Abstract: A method is taught for the high speed, continuous electrophoretic deposition of a dense, uniform, and defect-free metallic oxide coating on a substrate, wherein bubbles of inert gas are passed adjacent the fiber core during its passage through the electrophoresis cell to disperse and remove hydrogen gas from the cell during electrophoresis.
