  • Electronic device incorporating magnetoresistive elements for sensing both N and S magnetic poles
    Patent number: 7288934
    Abstract: An electronic device has a display housing (second body), an operation housing (first body), and a connection member connecting the display housing to the operation housing. A magnet is provided within an intermediate section of the connection member. A first magnetoresistive effect element is provided within the operation housing, and a second magnetoresistive effect element is provided within the display housing. The magnetoresistive effect elements and the magnet are disposed such that the magnetoresistive effect elements can sense a horizontal magnetic field to enable detection of both a open/closed state of the electronic device and a normal/reversed state of the display housing.
