Abstract:
Apparatuses and methods of distinguishing between a finger and stylus proximate to a touch surface are described. One apparatus includes a first circuit to obtain capacitance measurements of sense elements when a conductive object is proximate to a touch surface. The apparatus also includes a second circuit coupled to the first circuit. The second circuit is operable to detect whether the conductive object activates the first sense element, second sense element, or both, in view of the capacitance measurements. To distinguish between a stylus and a finger as the conductive object, the second circuit determines the conductive object as being the stylus when the second sense element is activated and the first sense element is not activated and determines the conductive object as being the finger when the first sense element and the second sense element are activated.

Claim (Index 21):
An apparatus comprising:\n a processing device coupled to a first electrode and a second electrode, wherein an inner perimeter of the first electrode surrounds an outer perimeter of the second electrode, wherein the processing device is configured to:\n measure a first capacitance of the first electrode and measure a second capacitance of the second electrode; \n measure an additional capacitance of the second electrode responsive to the second electrode being in proximity to a conductive object and the first electrode not being in proximity to the conductive object; and \n distinguish between a first type of conductive object and a second type of conductive object based on the first capacitance and the second capacitance,\n wherein the conductive object is the first type when the second capacitance indicates that second electrode is in proximity to the conductive object and the first capacitance indicates that the first electrode is not in proximity to the conductive object, and \n wherein the conductive object is the second type when the first capacitance of the first electrode and the second capacitance of the second electrode indicate that the conductive object is in proximity to both the first and second conductive objects.
