Patent ID: 11955702
Assignee: NEDAP N.V.
Field: Other special machines (Mechanical engineering)
Classification: CPC A  H  G | IPC G  H

Claim 0:
1. A detection label comprising:
a passive resonant circuit that, while having a status in a first state, is configured to emit an identification code responsive to the passive resonant circuit being introduced into a first electromagnetic interrogation field;
a memory; and
an active circuit comprising a transmitter and a receiver,
wherein the active circuit is configured to emit information stored in the memory with the transmitter responsive to the active circuit being introduced into a second electromagnetic interrogation field comprising a first predetermined code,
wherein the second electromagnetic interrogation field is received by the label using the receiver,
wherein the label is configured, in response to receiving the second interrogation field and the second interrogation field comprising a second predetermined code, to control the passive resonant circuit to adjust the status of the label to a second state such that the passive resonant circuit does not emit the identification code responsive to the passive resonant circuit being introduced into the first electromagnetic interrogation field.
