BRAKE DISK, PARTICULARLY FOR MAGNETIC BRAKING

摘要

An interactive assembly including at least one interactive surface element, at least a first region of the at least one interactive surface element having first user sensible functionality and at least a second region of the at least one interactive surface element having second functionality, different from the first user sensible functionality, input sensor functionality, including at least one input sensor located in propinquity to at least one of the at least one interactive surface element, operative to sense impingement of an electromagnetic radiation spot on at least one of the at least one first region and the at least one second region of the at least one interactive surface element and utilization functionality for employing outputs of the input sensor functionality in respect of impingement on either or both of the at least one first region and the at least one second region.
