ORIENTATION-AGNOSTIC METHOD TO INTERFACE TO XEROX PRINTED MEMORY LABEL

摘要

An electronic system for identifying an article can include a printed memory (100) having a plurality of contact pads (108) electrically coupled to a plurality of landing pads (206) positioned on a first side of a printed circuit board (200) substrate (204). The plurality of landing pads (206) can be electrically coupled to a plurality of endless, concentric contact lines (302) positioned on a second side of the PCB substrate (204) through a plurality of vias (210A-J) that extend through a thickness of the PCB substrate and a plurality of traces (208) that electrically couple the plurality of vias (210A-J) with the plurality of landing pads (206). To perform a memory operation on the printed memory (100), contact probes (602) of a reader (600) are physically and electrically contacted with the plurality of concentric contact lines (302). In some implementations, the memory operation can be performed on the printed memory (100) irrespective of a rotational orientation of the printed memory (100) relative to the reader (600).
