The invention relates to a headlight (2) for a vehicle (1), operating on the projector principle, comprising a housing (5), a light source (6) for visible light in the housing (5) and an optical element (5a) for shaping the light distribution. Said headlight has a second light source for infra-red radiation, arranged outside the housing (5), in particular separate therefrom and a light waveguide (4). The second light source (3) is thus optically connected to the housing (5) such that the IR radiation generated by the second light source (3) is injected into the housing (5) by means of the light waveguide (4), released in the vicinity of the first light source (6) and can be superimposed on the visible light. Said headlight is characterised by a particular degree of safety for the eye and a simple, economical and robust construction. The invention further relates to a headlight system in addition to the headlight, and an arrangement for improving the vision in vehicles with such a headlight or headlight system.

The invention relates to a laser-plasma hybrid welding method, whereby in order to weld workpieces, a laser beam (10) and a plasma beam (11) are brought together in the process area located near the workpieces. According to the invention, the free microwave-induced plasma beam (11) is produced using the following method steps: generating microwaves in a high-frequency microwave source; guiding the microwaves in a waveguide (1); introducing a process gas into a microwave-transparent tube (2), which has a gas inlet opening (14) and a gas outlet opening (15) at a pressure p >/= 1 bar, whereby the process gas is introduced into the microwave-transparent tube (2) via the gas inlet opening (14) so that it has a tangential flow component; producing a plasma (12) inside the microwave-transparent tube (2) by igniting the process gas without the use of electrodes; producing a plasma beam (11) by introducing the plasma (12) into the working space (16) via a metallic nozzle (1) located at the gas outlet opening (15) of the tube (2).

The invention relates to a motor vehicle door comprising an outer module (4) and an inner module (6), the inner module (6) having an inner door lining disposed on a supporting surface (8) of the inner module (6). The invention is characterized in that the inner module (6) has a carrier structure (10) provided with a metallic frame (12). The metallic frame (12) is joined to a plastic base carrier (14) so as to form a metal-plastic hybrid component (16) which simultaneously forms the supporting surface (8) of the inner door lining.

The invention relates to a drivetrain, comprising an internal combustion engine and two electrical drive units (hybrid drive). According to a conventional embodiment, a superimposition of the drive torque of an electrical drive unit over the drive torque of an internal combustion engine is achieved by means of a planet gear, the torque of the internal combustion engine being introduced thereto by the sun gear. The transfer of the torque of the electrical drive unit is achieved with different switching position of a clutch by driving various ring gears in the planet set. The aim of the invention is to disclose an improved drive train with regard to the drive ranges. Said aim is achieved, whereby the electrical drive unit (32) may be directly coupled to the input shaft (E) by means of a clutch (KE), or the a sun gear (SE) in the pick-off gear (TE), by means of a clutch (KG). Improved drive possibilities are thus generated, with the operation of the drive train either as a conventional automatic gearbox or as a stepless gearbox with two driving ranges The above is of application to a drive train for a motor vehicle.

A common problem faced by speech dialog systems is that they have to serve users with varying degrees of experience of such a system in an optimal manner. The invention relates to a speech dialog system that differentiates between inexperienced and experienced users and generates speech prompts that are adapted accordingly. The system is able to differentiate between inexperienced and experienced users, issuing a detailed speech prompt to the former and an abbreviated speech prompt to the latter. According to the invention, the speech dialog system initialises a dialog step using an abbreviated speech prompt. If the system user does not react to the abbreviated speech prompt after a specified time (recognition timeout), a detailed speech prompt is issued. Thus both types of speech prompts are issued for each dialog step and are available to the system user for selection. The user can therefore always select the type and manner of dialog he or she requires. The experienced user therefore always has the option of taking the initiative with regard to the course of the dialog. If at one point in the speech dialog he or she is unsure of the type of speech response that is expected by the speech dialog system, he or she can simply wait for the recognition timeout and then receive a detailed speech prompt.

The invention relates to a motor vehicle, especially a utility vehicle, with an electronically controlled drive train that comprises at least one drive unit, one steering system and one braking system. In order to simplify maneuvering of the motor vehicle, a maneuvering assistance system (6) is provided which comprises a display unit (7), an input device (8) and a control (9). The display device (7) is adapted to display an actual orientation and an actual position of the vehicle and the immediate vicinity of the vehicle on a screen (10). The input device (8) is adapted for the input of a desired orientation and a desired position of the vehicle. The control (9) is adapted to process a maneuvering algorithm (12) and controls the drive train in such a manner as to transfer the vehicle from its actual orientation and actual position to its desired orientation and desired position while taking into account the environment surrounding the vehicle.
