Abstract (en)
[origin: EP1286313A2] An electromagnetic field is generated between transmitter and receiver coils (14,16). The transmitter coil is acted on by short transmission pulse for which maximal attenuation values are determined. The attenuation values measured are extrapolated into time zero, and compared to preset acceptance band for measuring coin diameter. An Independent claim is also included for a coil assembly.
