Abstract: A handle stem for a bicycle, having a body and a lid, which can be fixed to the body, the body and the lid forming together a handle bar receptacle for receiving the handle bar of the bicycle, has a clamping ring being formed separate from the body and being inserted into a ring receptacle of the body for receiving the forked shaft of a fork of the bicycle.

Abstract: In a rotor system, in particular for a bicycle (1), on which a frame (3) bears a fork (8) for the front wheel (10), and a handle bar (18) is connected to the fork (8) by means of a handle stem (14) on a fork shaft (12) of the fork (8), with a first line (52), for a fluid, associated with the handle bar (14), with a second line (55), for a fluid, associated with the frame (3), and a rotor that contains two components (14, 41) that can rotate relative to each other without limits and that, by intimate contact against each other, create a closed fluid connection between the first line (52) attached to one component (14) and the second line (55) attached to the second component (41) in order to transmit the actuation of an actuation mechanism (50) associated with the handle bar (18), the handle stem (14) is one of the two components (14, 41) that can rotate relative to each other without limits and contains at least one chamber (30) included in the fluid connection between the two lines (52, 55).

Abstract: The present invention refers to a bicycle hub being part of the drive mechanism 1 of a BMX bicycle comprising: an axle 5, a first part 7 being seated on said axle 5 and being provided with or connected to a cog 6, a second part 8 being movable relative to said first part 7 in longitudinal and rotational direction of said axle 5, said first part 7 and said second part 8 being in contact with each other via a screw coupling provided by threads 7? and 8?, a hub body 11 being arranged around at least said second part 8, said second part 8 being provided with a first cone surface 9, said hub body 11 having a second cone 10 surface formed thereon or connected thereto, wherein said two cone surfaces 9, 10 are engageable for power transmission, wherein an adjustable stopper mechanism 12 is provided, limiting a gap providing space for an axial movement of said second part 8.

Abstract: Methods and systems, including computer program products, implementing techniques for configuring data structures. The techniques include receiving a description of a logical structure of a data model, the logical structure comprising a first set of elements; displaying a first display structure in a graphical user interface (GUI), the first display structure being a graphical representation of the description of the logical structure, the first display structure comprising visual representations of the elements of the logical structure; generating a data structure based on one or more user-selected visual representations of the elements of the logical structure, the data structure comprising a second set of elements; and displaying a second display structure in the GUI, the second display structure being a graphical representation of the data structure, the second display structure comprising visual representations of the elements of the data structure.

Abstract: In a rotor system, in particular for a bicycle (1), with at least one first rotor (31) for the transmission of brake actuations, which is mounted in the area of a handlebar stem (12) of a fork (8), whose support is provided by a steering head tube (21), and which has two components (32, 51) that are rotatable with respect to each other without restriction, wherein one component (32) is in active connection with a brake actuation device and the other component (51) is in active connection with a brake, the first rotor (31) is mounted inside the steering head tube (21), which serves as a casing for the first rotor (31), or above the steering head tube (21), the transmission of the brake actuation takes place by way of a fluid (F) that penetrates to the first rotor (31), and the first rotor (31) has an external piece (51) mounted outside the handlebar stem (12) and an internal piece (32) mounted inside the handlebar stem (12) as components that are rotatable relative to each other.

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: A form with a plurality of layout items for data presentation by a business application is defined by—simultaneously and one a single screen—providing (410) a tree view with tree nodes to represent the layout items, wherein the view visualizes structure information, a processing order, a selected tree node to represent a selected layout item; providing (420) a property view to display properties of the selected layout item; providing (430) a layout view to display items, wherein the selected layout item is highlighted; modifying (440) the selected layout item and the processing order through interaction with a user; and creating (450) a form definition document. The compatibility of layout items and processing order with a predefined data interface of the business application is verified as well.
