Example implementations include a method, apparatus, and computer-readable medium for electronic article surveillance (EAS), comprising transmitting an acousto-magnetic (AM) interrogation signal into an AM interrogation zone of an EAS system. The AM interrogation zone and a wireless communication zone overlapping to form a zone of interest. The wireless communication zone employing a wireless communication technology other than AM. Indicating, by the EAS system, a presence of a first tag of the EAS system in the zone of interest upon a concurrent detection of both i) a response signal of the first tag via the wireless communication technology and ii) an AM response signal of the first tag in response to the AM interrogation signal.

Radio frequency identification (RFID) tag location verification using acousto-magnetic detection

Deploying at each transition between separate areas of a facility a plurality of RFID reader antennas. Each antenna is deployed at a given transition covering a span of the given transition from a different perspective such that each point in the span is covered by at least two antennas. The antennas of a first transition between a first area and a second area of the separate areas detect, and in combination with an RFID system in communication with the antennas of the first transition, a tag known to have been in the first area. The RFID system identifies an item associated with the detected tag as moving to the second area. The antennas of a particular transition of the second area subsequently detect, in combination with the RFID system in communication therewith, the tag, and identifying the detected item as leaving the second area for an area across the particular transition.

Transition zone RFID tag management

A device for removal and installation of a pitch bearing on a wind turbine having a plurality of blades is provided, comprising a platform having a frame, wherein the platform includes a first bearing attachment member on a first side of the frame, and having a first pair of opposing bearing connectors matably engageable to the pitch bearing; a second bearing attachment member on a second side of the frame, and having a second pair of opposing bearing connectors matably engageable to the pitch bearing; and a rigging member attached to the frame, wherein the rigging member includes at least one cable bracket adapted to receive a lifting cable. A method of removal and installing a pitch bearing using the platform is also provided.
