摘要： A magnetic core transceiver antenna for EAS marker detection is provided. The core includes a stack of amorphous alloy ribbons insulated from each other and laminated together. A coil winding of wire, also insulted from the ribbons, and connected to an electronic controller provides the transmitter and receiver modes. The transceiver antenna is optimized for the dual mode operation, and is smaller and uses less power than conventional air-core EAS antennas with equivalent performance. Complex core geometries, such as a sandwiched stack of different sized ribbons, can be implemented to vary the effective permeability of the core to customize antenna performance. Multiple transceiver antennas can be combined to increase the size of the generated EAS interrogation zone.

The A/D converter can have enhanced resolution and/or an extended dynamic range when the voltage level being tested is divided arid the reference voltage is reduced. A corresponding method comprises the steps of: successively scaling down a voltage to be converted to a series of stepped down voltage levels; applying the successively stepped down voltage levels to respective ones of the input pins; and, sequentially scanning and acquiring a plurality of scaled A/D converter values from the input pins.

摘要： A single antenna transmits and receives signals. The single antenna has first and second antenna loops substantially lying in a common plane and partially overlapping. First and second transceiver circuits are coupled to the first and second antenna loops respectively, for respectively generating in a first mode of operation first and second pulsed magnetic fields together defining an interrogation zone for a marker generating a characteristic response to the magnetic fields in the interrogation zone, and for receiving signals from the interrogation zone in a second mode of operation. The first and second transceiver circuits alternately generate the first and second magnetic fields substantially in phase with one another and substantially out of phase with one another. The partially overlapping antenna loops prevent detuning of the transceivers otherwise resulting from the phase alternating. Each of the first and second transceiver circuits has a phase controllable transmitter section and a phase controllable receiver section. A controller independently phase controls the transmitter and receiver sections. Each receiver section is coupled across the tuned circuit of its respective transceiver circuit.
