ABSTRACT:
A magnetic field sensing device can be realized by using a magnetic sensor in electronic compassing as well as switching. A magnet can be brought in close proximity to the magnetic sensor within an electronic compass to generate a signal that a portable information device has been closed. This signal can be input to a processor or other circuitry to initiate a response to the portable information device being closed. When the magnet is moved out of close proximity to the magnetic sensor, the magnetic sensor can be used in the electronic compass. Thus, a magnetic sensor can serve two functions, namely compassing and switching, reducing the need for separate sensors to perform both functions.
