  • Electronic device
    Patent number: 8089244
    Abstract: An electronic device includes a main body, at least two pins folded mounted to the main body, and at least two conductive assemblies received in the main body. Each of the conductive assemblies includes a locking member and a resilient member resisting the locking member, when the pins are pushed and substantially perpendicular to main body, each locking member is capable of locking with an end of one of the pins.
    Type: Grant
    Filed: June 10, 2009
    Date of Patent: January 3, 2012
    Assignees: Shenzhen Futaihong Precision Industry Co., Ltd., FIH (Hong Kong) Limited
    Inventors: Wei-Ming Zhang, Jun Lu, Jin Li

  • Liposome composition for delivery of nucleic acid
    Patent number: 7112337
    Abstract: A liposome composition for delivery of a nucleic acid in vivo or ex vivo is described. The liposomes in the composition are comprised of (i) a lipid that is neutral in charge at physiologic pH and positively charged at pH values less than physiologic pH and (ii) a lipid joined to a hydrophilic polymer by a dithiobenzyl linkage. The liposomes are associated with a nucleic acid for delivery to a cell.

  • Neutral-cationic lipid for nucleic acid and drug delivery
    Patent number: 6974589
    Abstract: A lipid represented by the formula: wherein each of R1 and R2 is an alkyl or alkenyl chain having between about 8 to about 24 carbon atoms; n=0–20; L is selected from the group consisting of (i) —X—(C?O)—Y—, (ii) —X—(C?O)—, and (iii) —X—CH2—, wherein X and Y are independently selected from oxygen, NH, and a direct bond; and Z is a weakly basic moiety that has a pK of less than about 7.4 and greater than about 4.0 is described.
