摘要： A radio frequency identification (RFID) enabled mirror includes a mirror comprising a reflective layer. The reflective layer comprises at least one layer of a metallic material. At least one portion of the reflective layer is removed to form a booster antenna from a remaining portion of the reflective layer. A dielectric coating is applied to the mirror where the reflective layer was removed. The RFID-enabled mirror further includes an RFID chip coupled to the booster antenna.

摘要： A flake-less molecular ink suitable for printing (e.g. screen printing) conductive traces on a substrate has 30-60 wt % of a C8-C12 silver carboxylate or 5-75 wt % of bis(2-ethyl-1-hexylamine) copper (II) formate, bis(octylamine) copper (II) formate or tris(octylamine) copper (II) formate, 0.1-10 wt % of a polymeric binder (e.g. ethyl cellulose) and balance of at least one organic solvent. Conductive traces formed with the molecular ink are thinner, have lower resistivity, have greater adhesion to a substrate than metal flake inks, have better print resolution and are up to 8 times less rough than metal flake inks. In addition, the shear force required to remove light emitting diodes bonded to the traces using Loctite 3880 is at least 1.3 times stronger than for commercially available flake-based inks.

摘要： An encoding module and related systems and components are provided. The encoding module includes a plurality of encoding elements arranged in an array of columns and rows and one or more switching elements configured to selectively connect the encoding elements to a reader. The connection of the encoding elements may be based on the location of a targeted transponder disposed among multiple adjacent transponders to ensure the selective communication with the targeted transponder only. The module is configured for various types and locations transponders to be used within a system, such as a printer-encoder. Each encoding element may include a loaded conductive strip comprising a loop shape portion and a shield that corresponds to the loop shape portion. In another embodiment, an access control system having an encoding module with the plurality of couplers and an access card having a plurality of transponders corresponding to the couplers is provided.
