  • Publication number: 20190167801
    Abstract: An injectable, nonaqueous suspension including at least one therapeutic agent suspended in a single component vehicle. The single component vehicle is a single amphiphilic material, such as a polyethoxylated castor oil or derivative thereof, a polyoxyethylene alkyl ether, a polyoxyethylene sorbitan fatty acid ester, a polyoxyethylene stearate, a block copolymer of polyethylene oxide-polypropylene oxide-polyethylene oxide, a block copolymer of polypropylene oxide-polyethylene oxide-polypropylene oxide, a tetra-functional block copolymer of polyethylene oxide-polypropylene oxide, or a tetra-functional block copolymer of polypropylene oxide-polyethylene oxide. A dosage kit that includes the injectable, nonaqueous suspension and a method of administering the injectable, nonaqueous suspension are also disclosed.

  • Patent number: 8245109
    Abstract: A method stores data and check bits for that data within a memory chip. The memory chip stores the data and check bits in a plurality of pages contained in the memory chip, each page including a plurality of storage locations with each storage location having an associated address. The method includes receiving data to be stored in the memory, calculating check bits for the received data, mapping the data to addresses associated with the storage locations in a given page in the memory chip, mapping the check bits to addresses associated with the storage locations contained in the same page as the data, and storing the data and check bits in the page. The method may be applied to a single memory chip or to multiple memory chips.

  • Publication number: 20090074831
    Abstract: Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. In addition, these therapeutic drugs, agents and/or compounds may be utilized to promote healing, including the prevention of thrombosis. The drugs, agents, and/or compounds may also be utilized to treat specific disorders, including vulnerable plaque, and atherosclerosis in type 2 diabetic patients. Therapeutic agents may also be delivered to the region of a disease site.

  • Patent number: 7221655
    Abstract: A method of caching counter values in network packet traffic sampling, includes: generating a pre-sample strobe; loading the pre-sample strobe into a counter cache; waiting for the next strobe; and generating a sample pulse when the next strobe arrives. An apparatus for counting packet values and for sampling the values, includes: a packet sampling processor including a counter cache, the packet sampling processor responsive to a pre-sample strobe so that the pre-sample strobe updates the counter cache, where a sample pulse is generated when the next strobe arrives.
