System for determining a property of an object that includes a provision of induction to generate a momentum of Fluid, a detector for Detecting the vibration of the physical object, a Processor coupled to the detector to determine the ownership of the object to determine a property; method D an object; and a Valve.

摘要

A system (100) for determining a property of an object (106) comprises an inducing arrangement (102), a detector (104) and a processor. The inducing arrangement (102) is configured to generate an impulse of fluid and for directing the impulse of fluid towards the object to induce a physical vibration of the object (106). The inducing arrangement (102) does not contact the object 106 when inducing the physical vibration of the object (106). The detector (104) is configured to detect the physical vibration of the object (106). The detector (104) does not contact the object 106 when detecting the physical vibration of the object (106). The processor is coupled to the detector (104) for determining the property of the object (106) based on at least the detected physical vibration.
