Filed:

Apr 13, 2009

Appl. No.:

12/422667

Inventors:

Eduardo Repetto - Bee Cave TX, US
David G. Booth - Austin TX, US

Assignee:

Dimensional Fund Advisors LP - Santa Monica CA

International Classification:

G06Q 40/00

US Classification:

705 36R

Abstract:

A computer-implemented method is provided for selecting a recommended investment portfolio based in part on socially responsible considerations. A portfolio of securities is identified for potential inclusion in the recommended investment portfolio. Socially responsible investing (SRI) scores are provided for the identified securities, and the identified securities are ranked relative to each other based on their SRI scores in a computerized ranking engine. A processor receives an entry of initial weightings for each of the identified securities, or data by which initial weightings for each of the identified securities can be objectively calculated; the ranking of the identified securities based on their SRI scores; and an SRI multiplier algorithm that is correlated with the relative ranking. The initial weightings or the data are unadjusted by socially responsible considerations. The processor uses a weighting calculation engine to calculate adjusted weightings for the portfolio of securities using at least the entered items.

Abstract:

A surgical device and end effector connection system therefor include an easy-to-engage mechanism for connecting a handle/shaft/actuation rod unit to an end effector. This mechanism may utilize an axially engageable inner ball/socket inner connection with a threaded outer connection, or an inner bayonet connection with either an outer bayonet connection or an outer threaded connection. In each of the embodiments, an outer portion of the end effector preferably is statically engaged with the shaft, and an inner portion of the end effector is engaged with the actuation rod such that axial movement of the actuation rod can actuate a tool end of the end effector. The present invention further relates to methods of use for the laparoscopy device.
