First Claim
Patent Images
1. A protective cover arranged to protect at least a display of a tablet device, comprising:
- a body portion having a size and shape in accordance with the display, comprising;
an inductive power transmitter arranged to wirelessly pass power to a corresponding inductive power receiver unit disposed within the tablet device by inductively coupling;
at least a first magnetic element, andat least a second magnetic element used to secure the body portion to the display in a closed configuration, wherein in the closed configuration the first magnetic element is detected by a sensor disposed within the tablet device, the detection altering a current operating state of the tablet device; and
an attachment mechanism for pivotally attaching the body portion to the tablet device.
