| 20120008953 | METHOD AND SYSTEM FOR TRANSMITTING TIME IN PASSIVE OPTICAL NETWORK - The present invention discloses a method and system for accurate time transfer in PON. An Optical Line Terminal (OLT) ranges Optical Network Units (ONUs) and obtains ranging information, then, triggered by the periodic Pulse per n Second (PPnS), generates a PPnS timestamp based on the local reference counter and the Time of Day (TOD) above second; OLT transmits the ranging information, the periodic PPnS timestamp and TOD to ONUs; ONUs predicts the time of the next second according to said periodic PPnS timestamp, TOD and ranging information, and outputs the corresponding PPnS. The invention is characterized by the combination of the features of PON point to multi-point and PON ranging into its time transfer method, the high accuracy of time transfer, and the low hardware costs for OLT and ONU, as well as the extremely small bandwidth occupancy. | 01-12-2012 |

| 20090298881 | Water-Soluble Artemisinin Derivatives, Their Preparation Methods, the Pharmaceutical Compositions and the Use Thereof - Water-soluble artemisinin derivatives, their preparation methods, the pharmaceutical compositions containing the same derivatives and the use thereof are disclosed. The artemisinin derivatives have following formula I. It has been proved by pharmacological tests that these compounds and compositions have evident immuno-suppressive activities, and may be used in the preparation of novel immuno-suppressants for treating the diseases caused by hyperfunction of human immunity (e.g. the auto-immune diseases such as lupus erythematosus, rheumatoid arthritis, multiple sclerosis and the like), and for inhibiting the graft rejection after cell or organ transplantation. | 12-03-2009 |
| 20110075308 | System and Method for Short Circuit Protection - In one embodiment, a system for providing short circuit protection is disclosed. The system has a supply circuit and a series switch. The supply circuit has a supply input and a supply output, and is configured to deliver an output current at the supply output, and to disable the supply output if the output current exceeds a first current limit. The series switch coupled between the supply output of the supply circuit and a supply node, and the supply node is configured to be coupled to a load. | 03-31-2011 |

| 20110207880 | PEROXIDIC FLUOROPOLYETHER AND ITS USE IN EMULSION POLYMERIZATION OF FLUORIN-CONTAINING MONOMER - The present invention provides peroxidic fluoropolyether and a fluorin-containing dispersion obtained from polymerization of fluorin-containing monomers in the presence of peroxidic fluoropolyether as a surfactant. The peroxidic fluoropolyether can be used as surfactant for producing aqueous dispersion of fluorin-containing monomer in place of PFOA or the salts thereof. Thus the amount of PFOA or the salts thereof is reduced and the natural environment is protected. In addition, applying peroxidic fluoropolyether as surfactant and combining it with adjuvants, such as initiator, can induce the reaction moderate and can be beneficial to the polymerization control, thus reducing the amount of initiator or shortening the reaction time. | 08-25-2011 |

| 20120041167 | POLY(GLUTAMIC ACID)-DRUG CONJUGATE WITH AN AMINO ACID AS A LINKER - A poly(glutamic acid)-drug conjugate with an amino acid as a linker, and nontoxic pharmaceutically acceptable salt thereof, are provided in the present invention. The drug is gemcitabine, paclitaxel or docetaxel. The α-carboxyl group in the amino acid is linked to 5′-hydroxy in gemcitabine molecule or linked to 2′-hydroxy in paclitaxel (docetaxel) molecule via an ester linkage. The α-amino group in the amino acid is linked to the carboxyl group in the poly-(L-glutamic acid) molecule via an amide linkage. The content of gemcitabine in the conjugate is 5-30% in weight, and the content of paclitaxel or docetaxel is 10-40% in weight. | 02-16-2012 |
