An electronic blanket (1) comprising a sheet (2) of a foldable material, a sensor array (3), including one or several sensors (31,32,33,34), and a sensor target (4) adapted to affect said sensor array, wherein said sensor array is adapted to detect presence of said sensor target (4), said sensor array (3) and said sensor target (4) being attached to said sheet (1). The blanket also comprises circuitry (5) arranged to generate a state variable in response to detections by said sensor array (3), wherein said sensor array (3) and said sensor target (4) are arranged so that said state variable indicates when said electronic blanket has assumed a given state. As the sensor array and the sensor targets are both attached to the sheet, they provide information related to the positioning of the blanket in relation to itself. |
