Abstract

A device and method for indicating a change of angle, the device (2) including a detector for detecting tiny changes of angle of a surface (1) on which it is mounted, mechanical means for amplifying detected changes, and means for providing an indication of detected changes above a pre-set threshold. The indication may be a warning signal or an indication of the quantity of change of angle.
