Patent number: 8081156Abstract: The invention is directed to a control element, particularly for automotive electronics, having programmable haptics. Moments of force or a variation of the friction moments are formed on a control element by dynamically adapting the operative currents of electromagnetic arrays in dependence of the adjustment path. The force/path behavior (tactile feedback) of the control element can be modified at will during use so that the actuation forces for different operative functions can be varied. The tactile feedback of the moments of force on the control element takes by way of a locking piece, which, for example, can be comprised of at least one locking disc and a spring, which can be rendered active or inactive via an electromagnetic array.Type: GrantFiled: May 19, 2006Date of Patent: December 20, 2011Assignee: Preh GmbHInventor: Anton Ruettiger

Publication number: 20110266123Abstract: The invention relates to a control element cap. Such control element caps are used, for example, for switches and/or keys in motor vehicles. In the known control element caps, the representation of a symbol is relatively diffuse and thus not always recognizable with a sufficient degree of reliability. Therefore, a control element cap is to be provided in which the sharpness, and thus the clearness of the symbol is improved; this is accomplished by a transparent carrier plate being disposed between a foil and a display, luminous or projection surface. The invention further relates to a manufacturing process associated therewith.Type: ApplicationFiled: December 3, 2009Publication date: November 3, 2011Applicant: PREH GMBHInventor: Martin Jeitner
