Abstract: A system and method for providing wireless synchronized operation of electronic article surveillance (EAS) systems are provided. The method may include communicating wirelessly between each of a plurality of controllers connected to a plurality of detectors of the plurality of EAS systems and receiving with a communications receiver of each of the controllers wireless communications from at least some of the other plurality of controllers. The communications receiver may be separate from a tag detection receiver.

Abstract: A multi-bit electronic article surveillance marker includes an antenna circuit and is powered by an interrogation field generated by EAS detection equipment and received by the marker's antenna circuit. The marker generates a multi-bit signal by selectively disturbing the interrogation field. The disturbances may be created by selectively short circuiting the marker's antenna circuit. All of the marker circuitry, including a coil that is part of the antenna circuit, may be provided as circuit elements formed on a semiconductor integrated circuit substrate.

Abstract: A honing template comprising longitudinally extending fingers adapted to surround a hone and the ends of which carry template segments having inner abutment surfaces that are spaced to abut non abrasive surfaces that are in line with the stones when the stones are expanded to the finished diameter of the cylinder being honed. The inner abutment surfaces of the segments have a radius at least as great as the maximum radius of the cylindrical surface to be honed. The fingers have a tapered surface that is abutted by an annular ring which is wedged over said tapered surfaces to adjust the radial position of the template segments.
