Patent ID: 11883248
Assignee: KONINKLIJKE PHILIPS N.V.
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 8:
9. The identifying system of claim 1 wherein the passive medical identification device comprises:
a first oscillator formed by the respective magnetic object and the respective restoring torque provider, and
a second oscillator formed by:
a) a further magnetic object, wherein the further magnetic object is arranged within the casing such that the further magnetic object is rotatable out of an equilibrium orientation when the external magnetic torque is acting on the further magnetic object, and
b) a further restoring torque provider, wherein the a further restoring torque provider is configured to provide a restoring torque to force the further magnetic object back into the equilibrium orientation when the external magnetic torque has rotated the further magnetic object out of the equilibrium orientation, in order to allow for a rotational oscillation of the further magnetic object excited by the external magnetic torque, wherein the processor is configured to determine at least one property from a group consisting of a distance between the first and second oscillators, an orientation of one of the first and second oscillators relative to the other of the first and second oscillators, and a coupling strength between the first and second oscillators, and to extract the identification data based on the determined at least one property.
