摘要:
A multifuel fuel cell system includes a hydrogen production unit; at least one fuel cell; means for heating a first catalytic converter element in the hydrogen production unit to an operating temperature which can be preset; means for metering liquid fuel, air, and optionally water to the catalytic converter element to produce a synthetic gas mixture containing hydrogen or a reformate; and means for passing the synthetic gas or reformate to further components of the hydrogen production unit which are connected between the catalytic converter element and the at least one fuel cell. The fuel cell system also contains means for switching the fuel cell system between a first and a second operating mode. Separation occurs between the hydrogen production unit and the at least one fuel cell during the first operating mode, and a communicating connection occurs between the hydrogen production unit and the at least one fuel cell during the second operating mode, so that reformate can be transferred from the hydrogen production unit to the at least one fuel cell only during the second operating mode.

A data structure for use by a computer system for comparing temporally varying medical data (9a, 9b) is disclosed. The data structure performs the steps of receiving a first data set (9a) including first data representing a medical parameter at a plurality of first times, receiving a second data set (9b) including second data representing said medical parameter at a plurality of second times, and processing said first and/or second data sets to increase a degree of correlation or similarity between a plurality of said first and second times representing identifiable events.

The invention relates to a method for the interactive segmentation of a structure contained in an object from a three-dimensional image of the object. In an expansion mode a region expansion process is carried out, the results of said process simply being completely or partly undone again in a contraction mode. A quasi-continuous similarity measure can be used to determine whether or not a voxel belongs to the structure to be segmented. The expansion taking place in the region expansion process always involves the voxels having the largest similarity measure each time.

A steering device for a motor vehicle comprises a stationary skeleton which has an essentially arc-shaped skeleton section, and an actuation member that is movably mounted on the skeleton section and that has two contact sections essentially opposite from each other. The actuation member surrounds the skeleton section with a ring-shaped cross section and extends between the contact sections continuously along the arc-shaped skeleton section.

The invention relates to a gas bag module cover, comprising at least one opening portion for closing an outlet opening, and a predetermined tear line along which the cover is opened in a restraint situation and which defines one opening portion of the cover. The gas bag module further comprises at least one first hinge portion provided on the cover the opening portion remaining connected with the cover via the first hinge portion when the cover is opened. The opening portion has at least one second hinge portion which divides the opening portion into partial sections and allows a movement of the partial sections relative to each other. Further, the invention relates to a vehicle steering wheel which is equipped with such a gas bag module cover.
摘要:
A method for manufacturing a throttle valve unit having a housing part and a valve flap part that can move in relation to it includes the steps of injection molding the housing part of a first plastic material in a first cavity, transferring the molded housing part to a second cavity spatially decoupled from the first cavity, and injection molding the movable valve flap part out of a second plastic material in a second mold cavity inside the molded housing part. Before the molded housing part is transferred to the second cavity, it is subjected to an intermediate treatment in order to influence the shrinkage behavior, thereby selectively adjusting the gap geometries between the parts.
摘要:
A method and apparatus for interactively manipulating a shape of an object, comprising selecting an object to be manipulated and rendering the object in dependence of a manipulation type. The method provides a smart object adapted interaction, manipulation and visualization scheme in contrast to previous display driven schemes. The method allows efficient shape manipulation by restricting the degrees of freedom for the manipulation to the meaningful ones for a given object or object part, thus allowing to reduce e.g. a 3D interaction to a 2D interaction.

An actuator (1) has two parts in the iron circuit and has a simple construction. A short-circuit element (3) has an offset (90), which depending on the position of an armature (9) varies the course (60) of magnetic flux in such a way that over the entire stroke, a constant, high magnetic force is achieved, and thus a shallow course of magnetic force in stroke is attained.

A gas bag has an exterior wall having a front side that, in the inflated state, faces the occupant, a rear side and a circumferential side and at least one inflation opening. The inflated gas bag has a deep, channel-shaped indentation that extends toward the inflation opening. The indentation is not filled with compressed gas and at least one annular chamber to be filled with compressed gas is formed between the indentation and the circumferential side. At a distance from the front-side end of the indentation at least one flexible closure part is provided, which is connected in sections to the exterior wall. The closure part, when the gas bag is fully inflated, closes the indentation at least partially and, when the gas bag is folded, can be displaced in order to expose the indentation.

An arrangement for fastening a steering wheel to a steering column comprises a steering shaft end with a contact surface for a steering wheel hub to rest on. The steering shaft end has a slit extending along a steering shaft axis, which slit produces at least two opposite steering shaft end sections. The arrangement includes a device for optionally altering a slit width.
