  • TWELVE-CORNERED STRENGTHENING MEMBER
    Publication number: 20170106915
    Abstract: A crush can to an automotive vehicle has a twelve-cornered cross section comprising sides and corners creating internal angles and external angles. A geometry of the cross section varies between a front section and a rear section of the crush can. The geometry of the cross section is optimized using a plurality of control parameters including a lateral width, a vertical width, a taper ratio, a front scaling factor, and a rear scaling factor.

  • Twelve-cornered strengthening member
    Patent number: 9533710
    Abstract: A method for optimizing a twelve-cornered strengthening member comprises: modeling a vehicle assembly including a strengthening member having a twelve-cornered cross section; parameterizing a geometry of the strengthening member with a plurality of control parameters; defining a design of experiment using the plurality of control parameters; modeling a vehicle using the vehicle assembly; simulating a frontal impact event with the vehicle; generating a response surface based on the frontal impact event; and determining a set of optimized control parameters for the strengthening member based on the response surface.

  • Isolated nucleic acid molecule encoding a variant human eukaryotic Intiation Factor 4E protein
    Patent number: 6596854
    Abstract: The invention provides a method of purifying human eIF-4E protein and amino acid sequence variants thereof having altered binding affinity for capped RNA. Using the described purification, amino acid sequence variants can readily be expressed, purified and tested. Both lowered and enhanced binding affinity variants are useful for modifying protein expression levels in vivo and in vitro.
