Appl. No.:

11/147274

Inventors:

David Greene - Washington DC, US
Marvin Randolph - Washington DC, US

International Classification:

G06Q 99/00

US Classification:

705010000

Abstract:

An automated voter registration campaign management system and method includes collecting information and determining of one or more parameters of registrations per hour, phone number percentages for new registrants, volunteer recruitment percentage, contact rate and verification rate.

Appl. No.:

7/407534

Inventors:

David G. Greene - Arden NC

Assignee:

Steelcase, Inc. - Grand Rapids MI

International Classification:

B25B 1100

US Classification:

269 21

Abstract:

A programmable bed is provided for machine tools and the like, such as routers, boring tools, and other powered cutters and shapers. The programmable bed has a platen shaped to support differently sized workpieces thereon, and includes a plurality of retractable stops slidably mounted in the platen. The stops are selectively and individually shifted vertically between extended and retracted positions in response to the identification of a particular workpiece, so as to automatically locate or index the same on the platen at a preselected position relative to the machine tool. A plurality of pop-up suction chucks are also slidably mounted in the platen, and are selectively communicated with a source of vacuum. The suction chucks are reciprocated vertically between a retracted disengaged position, and an extended engaged position abutting an adjacent surface of the workpiece, so as to securely retain the workpiece in its preselected position during the machining operation.

- Anderson SC, US
David Greene - Arden NC, US

International Classification:

B65D 85/66
B65D 19/06
B65D 19/44

Abstract:

A base platform carrying a plurality of lower rail members on an upper surface. A pair of opposing laterally spaced end plates engaging the lower rail members. A series of lower positioning teeth formed in the lower rail members. A series of complementary lower connecting teeth included on the end plates engaging the lower positioning teeth. A plurality of upper rail members carried by the end plates. A series of upper positioning teeth formed in the upper rail members. A series of complementary upper connecting teeth included on the end plates engaging the upper positioning teeth of the upper rail members securing the end plates to the upper rail members. The series of upper and lower connecting teeth provide for the end plates to be repositionable along at least a portion of the upper and lower rail members to adjust spacing between the end plates to accommodate various roll sizes.
