  • Publication number: 20200015710
    Abstract: A device and method for measuring the amount of knee extension loss, hyperextension, or extensor length associated with arthritis, trauma, surgery or other medical conditions. This device and method includes measuring the difference in heel heights of a patient while patient is lying prone on a table with their legs, at the level of their knee caps, off the table. This device and method also measures extensor length in a patient's knee joint, by assessing heel height difference while a patient is lying prone on a table with a prone knee bend. This device and its methods provide accurate distance measurements that correlate to knee straightness and flexibility; these distinguishing metrics are unattainable by a standard “disc” goniometer. In addition, this device permits convenient measuring of a knee's mobility for two unique perspectives, namely in prone with legs straight or with a knee bent.

  • Patent number: 9934933
    Abstract: Extractors and extractor systems minimize the generation of secondary electrons which interact with and degrade the primary electron beam. This can improve the performance of an electron beam system, such as a scanning electron microscope. The extractor may include a frustoconical aperture that widens as distance from the source of the electron beam increases. The entrance into the frustoconical aperture also can include a curved edge.

  • Patent number: 7206059
    Abstract: A radial transverse electric polarizer device includes a substrate material having a first refractive index and a plurality of elongated azimuthally oriented elements coupled to the substrate material, the plurality of elongated elements having a second refractive index. The plurality of elements are periodically spaced apart to form a plurality of gaps such that the radial transverse electric polarizer device interacts with an electromagnetic radiation including first and second polarizations to reflect substantially all of the radiation of the first polarization and transmit substantially all of the radiation of the second polarization. The plurality of elongated elements are coated with this thin layer of absorbing material which absorbs radiation at a wavelength of the electromagnetic radiation. The polarizer device may be used, for example, in a lithographic projection apparatus to increase imaging resolution.

  • Patent number: 7022436
    Abstract: Attenuating phase shift masks and alternating phase shift masks provide increased resolution of the apparatus by introducing a phase shift in the radiation transmitted between adjacent features of the pattern on the mask. A phase shift mask is provided with a layer of inorganic material that is etchable. The inorganic material layer is formed on a mask blank having a glass or quartz layer and an etch stop layer. The etch stop layer provides uniform etch depth of the pattern in the inorganic material layer as the etch stop layer is formed of a material that is not etched by the etching process. The phase shift mask may be provided with a layer of attenuating material instead of the resinous inorganic polymer layer. The features of the pattern of the phase shift mask may also be filled with an optically transparent or translucent material or with an opaque material having an index of refraction and a dielectric constant selected to reduce the boundary effect at side walls of features of the pattern.
