  • Patent number: 7792403
    Abstract: The present invention relates to a waveguide structure, and methods for making the same. The waveguide structure has a polarization rotator for rotating the polarization of the electromagnetic signal, preferably by about ninety-degrees. In one embodiment, the polarization rotator has a midsection with a first level and a second level. The first level of the midsection has a width that decreases along the length of the first level, while the second level has a substantially constant width along the length of the second level. Further, the waveguide structure can include an input conditioning section and the output conditioning section to facilitate matching between the polarization rotator and other waveguide elements.

  • Patent number: 7787659
    Abstract: A computerized system for displaying, geolocating, and taking measurements from captured oblique images includes a data file accessible by the computer system. The data file includes a plurality of image files corresponding to a plurality of captured oblique images, and positional data corresponding to the images. Image display and analysis software is executed by the system for reading the data file and displaying at least a portion of the captured oblique images. The software retrieves the positional data for one or more user-selected points on the displayed image, and calculates a separation distance between any two or more selected points. The separation distance calculation is user-selectable to determine various parameters including linear distance between, area encompassed within, relative elevation of, and height difference between selected points.

  • Patent number: 7776591
    Abstract: A method of in vitro fucosylation of selectin ligands on cord blood-derived hematopoietic stem cells for bone marrow transplantation is disclosed. In this method, an effective amount of an ?1,3-fucosyltransferase, e.g., ?1,3-fucosyltransferase VI, is used in vitro to treat cord blood-derived hematopoietic stem cells to convert non-functional PSGL-1 or other ligands on the cell surface into functional forms that bind selectins, especially P-selectin or E-selectin. The treated cells have enhanced effectiveness in reconstituting bone marrow in patients in need of such therapy.
