  • Patent number: 8312196
    Abstract: A dual processor system comprises a first processor, a second processor, and a dual-ported random access memory (DPRAM). When the first processor stores data to be processed by the second processor to the DPRAM and writes interrupt data to the DPRAM, the DPRAM generates a first information status. The second processor reads the interrupt data once when detecting the first information status, processes the to be processed data when successfully reading the interrupt data once, and reads the interrupt data twice when completing processing the to be processed data. The DPRAM generates a second information status when the second processor successfully reads the interrupt data twice, and the first processor identifies that the second processor has processed the to be processed data when detecting the second information status.

  • Publication number: 20120009205
    Abstract: Disclosed is a process for preparing a pharmacologically active compound, in which at least one internal conjugation site of an Fc domain sequence is selected that is amenable to conjugation of an additional functional moiety by a defined conjugation chemistry through the side chain of an amino acid residue at the conjugation site. An appropriate amino acid residue for conjugation may be present in a native Fc domain at the conjugation site or may be added by insertion (i.e., between amino acids in the native Fc domain) or by replacement (i.e., removing amino acids and substituting different amino acids). In the latter case, the number of amino acids added need not correspond to the number of amino acids removed from the previously existing Fc domain. This technology may be used to produce useful compositions of matter and pharmaceutical compositions containing them.

  • Publication number: 20090191624
    Abstract: The present invention provides a means for increasing the serum half-life of a selected biologically active agent by utilizing transthyretin (TTR) as a fusion partner with a biologically active agent. Specifically, the present invention provides substantially homogenous preparations of TTR (or a TTR variant)-biologically active agent fusions and PEG-TTR (PEG-TTR variant)-biologically active agent fusions. As compared to the biologically active agent alone, the TTR-biologically active agent fusion and/or PEG-TTR-biologically active agent fusion has substantially increased serum half-life.
