| 20120069965 | METHOD FOR POSITIONING AN INSTRUMENT - A method of positioning a surgical instrument is provided which includes mapping a volume adjacent an operating table by taking mapping images from two orientations of a calibration object which includes a 3-dimensional array of radio opaque markers in a known configuration. A patient is positioned on the operating table with a patient target area within a mapped volume, and an instrument holder carrying a known configuration of radio opaque markers positioned adjacent the target area. Further fluoroscopic target images of the target area and instrument holder are obtained from the two orientations and the target area then reconstructed in 3-dimensions by comparing the target images to the mapping images. An instrument holder orientation is then calculated from the reconstruction. | 03-22-2012 |
| 20110247311 | YARN AND A PROCESS FOR MANUFACTURE THEREOF - A yarn spun from a plurality of nano-fibres is provided and is characterized in that at least some of the nano-fibres are folded with the folds occurring at predeterminable distances which are integer multiples of a specific spacing. The folds result from spinning the nano-fibres onto a plurality of moving conductive strips which are inclined to their direction of movement. A process and apparatus for producing such yarn is also provided. | 10-13-2011 |
| 20110230114 | TOY EXHIBITING BONDING BEHAVIOR - A toy capable of exhibiting bonding behavior toward a user and a method of simulating such behavior. The toy includes input sensors for receiving interactive input from users, an output apparatus for communicating with users, a processor and memory containing machine instructions causing the processor to receive interactive input, process received input and send control signals to the output apparatus. The processor classifies received input as either positive or negative and adjusts an accumulated input, stored in the memory, in accordance with the classification. The control signals, in turn, are dependent on the accumulated input. | 09-22-2011 |

| 20110177542 | METHOD FOR ENHANCING CELLOBIOSE UTILIZATION - The present invention relates to methods for improving a host cell's ability to utilize the disaccharide cellobiose. In some embodiments, a transformed cell expresses intracellular β-glucosidase. In other embodiments, a transformed host cell is able to grow on media wherein cellobiose is the sole carbon source. In other embodiments, selection methods are provided which improve a host cell's ability to grow on cellobiose-containing media. | 07-21-2011 |
| 20110156321 | Method and Apparatus for the Production of Fine Fibres - A method and apparatus provided for the production of fine fibres by electrospinning fibres by applying an electrical field between a primary electrode and a counter electrode ( | 06-30-2011 |
| 20110129888 | Method for Fermenting Cellulosics - The present invention is directed to host cells capable of fermenting cellulosic materials for the production of ethanol. Microorganisms engineered to be able to use amorphous cellulosic materials in a fermentation process to produce ethanol are disclosed. Additionally, methods of using the host organisms of the invention and compositions for producing ethanol according to the invention are disclosed. | 06-02-2011 |
| 20110124074 | Heterologous Expression of Fungal Cellobiohydrolases in Yeast - The present invention provides for heterologous expression of polypeptides encoded by wild-type and codon-optimized variants of cbh1 and/or cbh2 from the fungal organisms | 05-26-2011 |
| 20110098359 | Compositions and Methods for Treatment of Glaucoma - A new use for paracetamol in a method of treating glaucoma, which method comprises administering to a patient in need of such treatment 500 mg to 1000 mg of paracetamol in oral format 4 to 6 hourly. An ophthalmic solution is also provided containing between 0.1 to 5% of paracetamol which is administered as one to two drops in each eye 4 to 6 hourly. The ophthalmic solution further includes one or more of the following excipients: hydroxypropylmethylcellulose, benzalconium chloride, polyacrylic acid such as Teargel®. | 04-28-2011 |
