  • Publication number: 20220015855
    Abstract: Various implant holding systems are provided herein that include an outer tube, an inner tube, and a holder. The implant holding systems can be designed to hold various implants, such as bone anchors used in spinal operations. For example, one embodiment of an implant holding system can have an outer tube, an inner tube that can be disposed within the outer tube, and an implant holder that can be disposed within the inner tube. An individual bone anchor that has various configurations and sizes can be disposed within the holder, and the holder can engage the bone anchor to assist in maintaining an orientation of the bone anchor relative to the holder.

  • Publication number: 20220022005
    Abstract: Systems, methods, and computer-executable instructions for providing privacy to relative location data includes receiving a request for a location of an object. Privacy settings associated with the object are retrieved. A position of the object within a construct of a physical space is determined. An area within the construct of the physical space based on the position is determined. A location value of the object based on the area and the privacy settings is determined. The location value in response to the request for the location of the object is returned.

  • Patent number: 9599507
    Abstract: A fiber optic probe assembly is provided. The probe comprises a first optical system and a second optical system, a delivery light guide comprising one or more than one delivery optical fiber for transmitting excitation radiation from a radiation source disposed at a proximal end of the light guide to the first optical system. The first optical system comprising one or more than one first optical element for forming a substantially collimated illumination beam from the excitation radiation. An optically opaque tubular sleeve is fitted over the first optical system to optically isolate the first optical system and the delivery light guide from the second optical system. The second optical system comprising one or more than one second optical element for gathering optical radiation scattered from a sample and forming the optical radiation into a collection beam.

  • Patent number: 8882274
    Abstract: The device and method of the present invention are useful for determining the characteristics of an infrared wavefront. The present invention involves positioning a beam of light containing the infrared wavefront to be characterized onto a distorted grating, using the grating to produce a plurality of images, determining the infrared wavefront from the plurality of images and analyzing the infrared wavefront for features that characterize the infrared wavefront.

  • Publication number: 20130225951
    Abstract: A method and system of acquisition and processing of data representing oxygen saturation (OS) value of a tissue of a visual system of a subject, such as the optic nerve head and overlying artery and vein. The data is acquired at pre-determined discrete spectral points, including at least two isosbestic points, as a discrete reflectance spectrum, with the use of a multi-spectral optical imaging system that simultaneously produces a plurality of two-dimensional spectrally-discrete images by segmenting an incoming light front with secondary objectives. The OS value is assessed based on determination of areas bound by an acquired discrete reflectance spectrum and an isosbestic line.

  • Patent number: 8072049
    Abstract: A polysilicon resistor fuse has an elongated bow-tie body that is wider at the opposite ends relative to a narrow central portion. The opposite ends of the body of the fuse have high concentrations of N-type dopants to make them low resistance contacts. The upper portion of the central body has a graded concentration of N-type dopants that decreases in a direction from the top surface toward the middle of the body between the opposite surfaces. The lower central portion of the body is lightly doped with P-type dopants. The central N-type region is a resistive region.

  • Publication number: 20070022706
    Abstract: A service line distribution base (10) comprises a ground anchor (18) having an upstanding cruciform portion adapted to extend into the ground. A cabinet (20) suited to support a utility pole (14) extends upwardly from the ground anchor (18). The cabinet (20) defines and internal space for receiving buried wire conduits (28) incorporated to the cruciform ground anchor (18). The cruciform shape of the ground anchor (18) advantageously permits to incorporate a greater number of wire conduits (28) into the base of a utility pole as compared to conventional concrete bases.

  • Patent number: 6780274
    Abstract: A fiber collimator is provided, comprising at least two optical components, one of the optical components (e.g., an optical element such as a collimating lens or a plano-plano pellet) having a surface that has a comparatively larger cross-sectional area than the surface of the other optical component(s) (e.g., at least one optical fiber). The optical components are joined together by fusion-splicing, using a laser. A gradient in the index of refraction is provided in at least that portion of the surface of the optical element to which the optical fiber(s) is fusion-spliced or at the tip of the optical fiber. The gradient is either formed prior to or during the fusion-splicing. Back-reflection is minimized, pointing accuracy is improved, and power handling ability is increased.
