Abstract: A steering wheel for a motor vehicle is disclosed. The steering wheel includes an optical finger navigation module, at least one further operating element, a steering wheel electronic system and a databus for data transmission between the optical finger navigation module and the steering wheel electronic system. The at least one further operating element is directly connected to the optical finger navigation module via a signal line. The optical finger navigation module is designed in such a way as to receive a signal from the at least one further operating element and relay it on to the steering wheel electronic system via the databus. In this way, no dedicated lines from the operating element to the steering wheel electronic system are necessary. Thus, the construction space for the installation of a device consisting of an optical finger navigation module and a further operating element in a steering wheel is reduced.

Abstract: In certain configurations and applications, fuel cell stacks can be subject to damage arising from resonance. For instance, the natural frequency of lengthy automotive fuel cell stacks can be low enough to be problematic. Incorporating appropriate support bars between the compression straps holding such stacks together and the fuel cells in the stack can suitably increase the natural frequency in a relatively compact manner.
