Abstract
Apparatus and methods that determine the positional state of a lid body relative to a chassis body based on a detected amount of magnetic flux are disclosed. One apparatus includes a lid body including a first magnet and a magnetic sensor and a chassis body including a second magnet. The magnetic sensor is configured to detect an amount of magnetic flux from the first magnet and the second magnet is positioned on the chassis body to influence the amount of magnetic flux detected by the magnetic sensor based on the relative positions of the lid body and the chassis body.
