Abstract: An apparatus including a slider part and a base assembly slidingly movable in relation to each other with the aid of a first guide rail and a second guide rail in the base assembly. The distance between the first guide rail and the second guide rail is adjustable while the apparatus is being assembled. A method is also disclosed.

Abstract: An apparatus including a first rail part and a second rail part which are allowed to slide with respect to each other. The apparatus further includes a wearable protrusion in one of the rail parts to set a pre-defined clearance between the rail parts. A method is also disclosed.

Abstract: An apparatus having in a mutually rotatable configuration, a first fluid shear member connectable to a first moveable body part of a handheld device and a second fluid shear member connectable to a second moveable body part of the handheld device. The first and second fluid shear members are configured to experience mutual rotation when the first and second moveable body parts are connected respectively to the first and second fluid shear members and when the moveable body parts are moved in relation to one another. The first and second fluid shear members are matched and there is fluid between the first and second fluid shear members so as to invoke viscous dampening when the first and second fluid shear members rotate in relation to one another.

Abstract: A hinge structure is shown for use in portable electronic devices, making it possible to turn a first housing part and a second housing part of the device in relation to an axis of rotation of a hinge structure, the hinge structure comprising a torsion spring, which has a first end and a second end and a longitudinal axis, and the first end of the spring is connected to a first hinge half and the second end of the spring is connected to a second hinge half in such a manner that the connection point of the second end of the spring is able to rotate around the axis of the spring.
