Abstract
A tilt detector includes a magnet, a plurality of magnetoelectric transducers, a container, and a mounting member for mounting the magnet. The mounting member is rotatably supported within the container and the plurality of magnetoelectric transducers is mounted on the container. The tilt detector detects a tilt condition from signals generated by the magnetoelectric transducers due to changes in a relative position of the magnet and the magnetoelectric transducers as the mounting member rotates within the container.
