摘要： An article, system and method related to a magnetomechanical marker used to mark stationary assets. Magnetomechanical markers can be arranged in clusters and associated with stationary assets, including assets buried underground. Markers can be associated with an asset by being attached to the asset, arranged in a particular spatial relationship with the asset, or in any other appropriate way. A portable locating device can be used to generate an alternating magnetic field to activate the magnetomechanical marker and thus locate the asset.

摘要： A single turn loop electronic article surveillance (EAS) gate. The gate includes a closed magnetic core, a multi-turn primary winding wound around the core, and a secondary loop passing through the core once. The secondary loop is a self-supporting single turn loop, and the secondary loop is a transmit loop that generates a magnetic drive field for the article detection gate system.
