  • Patent number: 10052831
    Abstract: A wave guide face plate for transmitting an image formed in a scintillating material included as part of a transmitting medium is disclosed. The transmitting medium includes a random distribution of different refractive index regions in two orthogonal dimensions, and an essentially consistent refractive index in a third orthogonal dimension. The third orthogonal direction is aligned with a transmission axis of the wave transmitter extending from an input location to a wave detector location. The transmission efficiency of the wave guide faceplate is improved in situations where the entry angle of the input radiation is different from the axis of the wave transmitter as compared to conventional faceplates.

  • Publication number: 20170341988
    Abstract: A system and method for disposing carbon dioxide is disclosed. The system includes a foam generator that generates a plurality of disposable foam vessels from a polymer based solution mixed with water and captured carbon dioxide from the atmosphere. The plurality of disposable foam vessels contains an amount of carbon dioxide. The plurality of disposable foam vessels is mixed in a cementitious material with a set of mixers. In a preferred embodiment, the set of mixers is a concrete mixing plant. During the curing process of the cementitious material the plurality of disposable foam vessels dissipates allowing for a timely release of CO2 to chemically react with the surrounding cementitious material. This irreversible chemistry change permanently disposes of the carbon dioxide.

  • Publication number: 20050265675
    Abstract: A method to fabricate solid linear fiber arrays, multi-hole arrays and inverse multi-hole arrays (i.e. space-separated arrays). These arrays may be used for example as capillary arrays, photonic crystal fiber, tissues engineering scaffolds and templates, imaging guides, thermal photovoltaic device, and thermal electric devices. The number of fibers used to fabricate the structures is variable. Individual fibers are deposited into a fiber depository and made to bond together. The deposition may be performed in line with fiber production or may be performed after producing the fibers through fiber rewinding. The bonded linear fiber array may be removed from the fiber depositories.

  • Publication number: 20050203341
    Abstract: An endoscopic shaft having multiple endoscopic elements set in a polymer common housing. The endoscopic elements may be drawn with the common housing to manufacture a component, called an EndoFiber, which forms the length of the endoscopic shaft. A second structure, called an Endocap, may be provided that includes optical elements and which is attached to the end of the EndoFiber to form the shaft.

  • Publication number: 20040172268
    Abstract: An apparatus and method, referred to as MyHROnline, for providing employers with an easy, online way to create information about Benefits, Policies and Procedures and to make Benefit and Policy/procedures information available to their employees or others to whom they wish to offer access, such as job seekers (together, those will be referred to as “Employees”). You are not limited to the pre-programmed information. The wizard allows you to edit the pre-programmed information and/or create your own information about any benefit or policy that you would like and place the information on an interactive web site accessible by the employees. The site is as expansive or limited as you desire. MyHROnline lets you provide the information you want to your employees, then simply click “go live” to make the information available to your workforce. The site is fully hosted by the myHROnline server site and is available to your workforce 24/7.

  • Patent number: 6609302
    Abstract: A bolt cutting tool comprises a bolt engaging portion and a cutting blade. The bolt engaging portion has at least one bolt-receiving bore, which is adapted for receiving a portion of a bolt to be cut. The cutting blade is rotatably connected to the tool generally adjacent the bolt engaging portion. The cutting blade has a cutting surface with an arcuate peripheral cutting edge. The cutting blade is adapted for rotation relative to the bolt-receiving bore from a pre-cut starting position toward a post-cut finishing position. The blade is adapted to rotate in a manner so that the arcuate peripheral cutting edge of the blade cuts the bolt as the cutting blade is rotated toward the post-cut finishing position. The blade is configured so that an angle of incidence between the cutting surface of the blade and a center axis of the bolt-receiving bore is less than 15 degrees when the blade is in its pre-cut starting position.
