Abstract
A tilt detection device uses externally generated electromagnetic signal sources to detect changes in relative orientational positioning of an object. A sensor () monitors intensity characteristics of electromagnetic stimuli received from remotely located sources, and a controller () utilises changes in those characteristics to inform detection and/or measurement of a state of tilting of an object to which the sensor is mounted.
