Patent ID: 8514185

Claim:
A device, comprising: multiple mutual capacitive sensing nodes arranged along node paths that form an array, the array comprising multiple first node paths arranged in a first pattern and multiple second node paths arranged in a second pattern, the node paths being arranged such that when a first node path and a second node path intersect then the intersecting node paths form an angle of greater than or less than 90 degrees, each of the multiple mutual capacitive sensing nodes comprising an electrode pair formed in a first layer, each of the electrode pairs comprising a drive electrode and a sense electrode, and a controller configured to detect a capacitance value associated with each of the multiple mutual capacitive sensing nodes by driving the drive electrode and sensing the sense electrode of each of the electrode pairs, the capacitance value associated with each of the multiple mutual capacitive sensing nodes enabling differentiation between the presence of a touch and the absence of a touch at each of the multiple mutual capacitive sensing nodes.
