摘要： A system for minimizing the effect of null zones in an interrogation zone of a marker detection system. The system includes a reference antenna system configured to produce a first reference electromagnetic field during a first time period. The antenna system also includes a phase canceling antenna system configured to produce a second electromagnetic field substantially in phase with the reference electromagnetic field during the first time period and a third electromagnetic field substantially out of phase with the reference electromagnetic field during the first time period. The phasing of the first field or the second and third fields may be continuously switched while the phase of the other is held constant. A method of spatially shifting null zones in an interrogation zone of a marker detection system is also provided.

摘要： A magnetic core antenna system including a magnetic core and a winding network. The winding network may be configured with a non-uniform ampere-turn distribution to achieve a desired flux density in the core. The network may include a plurality of windings configured to provide a winding impedance facilitating optimal transmitter power delivery to the windings. A magnetic core may be constructed from multiple components having longitudinal contact surfaces and joined by a transverse clamping force. An air gap may be provided between the components to allow relative movement therebetween.

摘要： An electronic article surveillance system has a receiver with a plurality of receiving coils. Each coil in the system is treated as a separate detection unit with its own noise environment which is distinct from the noise environments of the other coils in the system. The picture of the noise environment is preferably expanded to include examining noise per coil per phase. Control apparatus has facility for changing the interconnection and configuration of the receiving coils responsively to the per coil and per phase noise environment analysis. Noise analysis and coil configuration change can be practiced concurrently with EAS system operation or may be practiced during periods in which the EAS system is rendered inactive.
