Abstract: The present invention yields high-quality, artifact free phase contrast images from an object using an arrangement of gratings. The new method suppresses the need of direct image integration and significantly improves the quality of phase contrast images. In comparison with existing techniques, our approach does not need additional alignment work nor increased exposure time. On the other hand it delivers excellent, direct interpretable information about the phase projection within a radiographic experiment. Due to its general applicability and its simplicity in usage, the suggested invention is expected to become a standard method for a variety of 2D imaging applications using gratings arrangements in particular on medical scanners (for instance mammography), inspection at industrial production lines, non-destructive testing, and homeland security.

Abstract: Artificial Insemination is achieved for sexed mammalian offspring in a commercially practical manner and with dosages of insemination sperm which were not previously thought to be practical for commercial implementation. Improved insemination systems particularly adapted to use for sex-selected sperm sorting include systems which achieve superovulation and then multiple embryo production with sexed embryos. These systems combine with other techniques, including techniques for enhanced sheath fluid (3) and other strategies which minimize stress on the sperm cells (18), and potentially, a 2.9 percent sodium citrate sheath solution for bovine species and a hepes bovine gamete media for equine species.  Improved collection systems (14) and techniques for the process are describe so that commercial application of sperm samples as well as the resulting animals may now be achieved in the field.

Inventor: SOLE ROJALS JOEL
IPC: H04N7/50
Filed: 2012-03-07
Abstract: This disclosure describes techniques for coding transform coefficients associated with a block of residual video data in a video coding process. Aspects of this disclosure include the selection of a scan order for both significance map coding and level coding, as well as the selection of contexts for entropy coding consistent with the selected scan order. This disclosure proposes a harmonization of the scan order to code both the significance map of the transform coefficients as well as to code the levels of the transform coefficient. It is proposed that the scan order for the significance map should be in the inverse direction (i.e., from the higher frequencies to the lower frequencies). This disclosure also proposes that transform coefficients be scanned in subsets as opposed to fixed subblocks. In particular, transform coefficients are scanned in a subset consisting of a number of consecutive coefficients according to the scan order.
