Abstract:
1. An apparatus for sensing deposition of sprayed droplets of liquid on a surface, comprising: a sensing surface; the sensing surface comprising a plurality of electrically conductive elements disposed across the sensing surface; wherein the conductive elements are closely spaced apart from each other and electrically insulated from each other on the sensing surface; and at least one comparator circuit coupled to the conductive elements; the comparator circuit configured to detect the presence of liquid at the conductive element; wherein the conductive elements are disposed in an array across the sensing surface such that information regarding the presence, distribution, deposition density, size, and location of the sprayed droplets of liquid on the sensing surface may be determined; and wherein a deposition map and summary data of the sprayed droplets of liquid may be produced from said information.
