A haptic operating device for vehicles. The device has a rotatable operating part, a magnetic field source, and a magnetorheological braking device for braking a rotational movement of the operating part. The magnetorheological braking device has two braking components which can be rotated relative to one another and one of which is coupled to the rotatable operating part. The second brake component, acting as an outer brake component, surrounds the first brake component that acts as an inner brake component. A closed magnetorheological brake chamber is provided with a magnetorheological medium and is formed between the two brake components and has a peripheral braking gap.

A flexible display device for a vehicle includes a casing having an opening, a display part to be retracted or extended into or out of the casing through the opening, a display driver configured to move the display part, and a display winder configured to wind the display part based on movement of the display part.

A compact work machine, such as a compact track loader and/or a compact utility loader, which can carry and operate a wide range of attachments while maintaining a reduced operating footprint.

The disclosure provides a projection module used in a vehicle. The projection module includes a partition and a projection device. The partition is disposed between a front seat and a rear seat of the vehicle and includes a substrate and an optical film disposed on the substrate. The optical film has a reflection axial direction and a transmission axial direction. The incident light has a first reflectivity and a first transmittance in the reflection axial direction, and a second reflectivity and a second transmittance in the transmission axial direction. The projection device is used to project a display light beam to the optical film of the partition. The first reflectivity is greater than the second reflectivity. The first reflectivity is between 20% and 100%. The first transmittance is between 0% to 80%. The second reflectivity is between 0% and 40%. The second transmittance is between 60% to 100%.

In an example, a lining arrangement for a back side of a flexible display unit which can be moved between a retracted and an extended state, may include at least two lining parts which are arranged adjustably between the retracted state and the extended state in accordance with the telescopic principle. The at least two rigid lining parts may be in form of at least two rigid lining panels which are arranged in plane-parallel fashion, with each rigid lining panel of the at least two rigid lining panels held together in pairs by an internal bearing arrangement that has guide elements arranged in cutouts in each rigid lining panel of the at least two rigid lining panels, and in this respect are mounted displaceably relative to one another along a displacement path in the plane-parallel fashion.

A display device for a vehicle comprises a display module having a display panel and a cover window disposed on one side of the display panel, and a drive mechanism for laying down the display module or standing the display module up, wherein the cover window may comprise: a total reflection area in which an image emitted from the display panel is totally reflected; and a transmission area in which the image emitted from the display panel is transmitted.

The disclosure relates to an optical waveguide for a display device and to a device for generating a virtual image using such an optical waveguide. The optical waveguide has two or more partial optical waveguides adapted to different wavelengths. At least one of the partial optical waveguides in this case has an optical filter. The optical filter is adapted to the wavelengths used.
