Abstract: An interactive computer system (901/902/903) feeds (31) customer input data (Z) into a business application (202). A first computer (901) designs a visual document appearance and thereby provides layout data (X) with interactive elements in a first document. A second computer (902) processes the first document by adding (102, 12) customer specific data (Y) from the business application (202), thereby provides a second document (302), and codes the second document (302, 312) into markup language having representations for the interactive elements. A third computer (903) with a browser displays a visual representation of the second document (302, 312) to a customer as designed and prompts the customer for input data (Z) through the interactive elements. The third computer (903) forwards (33) the input data (Z) to the second computer (902) through a third document (323) and the second computer (902) relates (104) the customer input data (Z) with customer specific data (Y) in the business application (202).

Abstract: An improved rotor system includes bearings that are carried by the frame of a bicycle. The bearings are carried by the frame so that a stem of a fork of the bicycle extends through the bearings and the fork is capable of being rotated relative to the frame about an axis that is generally coaxial with the stem. The improved rotor system further includes upper and lower transmission elements that extend around the stem and are movable along the stem. The upper transmission element is rotatable about the axis relative to the lower transmission element. The upper transmission element is connected to the first brake cable line and is operative for moving along the stem in response to actuations of the first brake cable line. The lower transmission element is mounted for moving with the upper transmission element along the stem. The lower transmission element is connected to the second brake cable line so that actuation of the first brake cable line results in actuation of the second brake cable line.
