Abstract:
1. A sensing surface for providing measured data indicative of a three-dimensional behavior of one or more objects thereover, comprising: an edge, at the periphery of the sensing surface, through which the sensing surface can be connected to electrical circuitry; a pads layer, in the area within said edge, comprising an insulating sheet and a plurality of sensing pads overlaying said insulating sheet, the sensing pads being arranged on said insulating sheet in a pattern configured such that each such sensing pad is isolated from one another and there is an electrical connection between each said sensing pad of said pattern and said edge, wherein at least some of said sensing pads are connected to said edge by means of a respective wire; and an upper shielding layer, in the area within said edge, comprising a conductive material isolated from but overlaying said wires, said upper shielding layer being capable of shielding the wires over which it lays from electrical effects that may be caused by proximity of the one or more objects to said wire when in use.
