Abstract:
1. A protective cover arranged to protect a tablet computer having a processor coupled to a display comprising a top protective layer, the protective cover comprising: a foldable flap having a first side and a second side opposite the first side, comprising: at the first side, a first magnet configured to provide a first magnetic field that passes through the top protective layer and is detectable by a sensor disposed beneath the top protective layer only when the foldable flap is in contact with the top protective layer in a closed configuration, and a second magnet separate from and adjacent the first magnet configured to magnetically secure the flap to the top protective layer at a first edge of the tablet computer by forming a magnetic attraction through the top protective layer by magnetically attracting a third magnet of opposite polarity disposed beneath the top protective layer at the first edge, wherein only when the sensor detects the first magnet, the sensor provides a first detection signal to the processor, wherein the processor responds to the first detection signal by disabling the display from presenting visual content.
