ABSTRACT:
An electromagnetic digitizer arrangement that may include a comb-like pattern of sensing traces that form various sensing loops depending upon the configurations of various switches is described. The comb arrangement of traces may be fabricated using only a single layer per sensing axis. Thus, the digitizer may be fabricated in a technology, such as indium tin oxide on glass, that cannot provide plated-through holes.
