Abstract: A printed circuit board (18) for electrically connecting to an optical subassembly (16) includes a board base (230), a conductive trace (232), and a board conductor (234). The optical subassembly (16) includes at least one component pad (346). The board base (230) is made of a substantially nonconductive material. Further, the board base (230) defines a recessed region (238) that is sized and shaped to receive a portion of the optical subassembly (16). The conductive trace (232) is secured to the board base (230). The board conductor (234) is positioned near the receiver region (238). Further, the board conductor (234) is positioned near the component pad (346) when the optical subassembly (16) is positioned in the receiver region (238). Moreover, the board conductor (234) is electrically connected to the conductive trace (232).

Abstract: Identification tags (22) are secured to objects (20) moving upon a transport band (16). The identification tags (22) each contain a transponder circuit (32) in electrical communication with transponder antennae (30, 31). The transponder circuit (32) contains a unique digital code containing data relating to the object (20). When the identification tag (22) is located beneath the object (20), at least one reader antenna (25) is positioned beneath the transport band (16) and in alignment with a selected aperture (34) extending through a support plate (12). One or more apertures (34) in alignment with the reader antenna (25) provide capacitive coupling between the transponder antennae (30, 31) and the reader antenna (25). The reader circuit (28) generates a signal in the presence of an identification tag (22), which is transmitted to the transponder antenna (30) located on the identification tag (22).

Abstract: Flexible tags are secured to parcels moving upon a conveyor belt. The flexible tags each contain a transponder circuit in electrical communication with a transponder antenna. The transponder circuit contains a unique digital code containing data relating to the parcel. A reader circuit located in proximity to the conveyor is in electrical communication with a reader antenna. The reader circuit generates a signal in the presence of a flexible tag, which is transmitted to the transponder antenna located on the flexible tag. The signal energizes the transponder circuit in the flexible tag, which sends a unique digital code via the transponder antenna back to the reader antenna. The digital code is transmitted from the reader antenna to the reader circuit, where the digital code is analyzed to identify the contents of the parcel. The flexible tags are agitated by forced air from a fan to orient the flexible tags in non-parallel alignment in relation to the reader antenna as they move along a conveyor.
