Apparatus and method for operating an oscillation blade device and a system comprising the apparatus

摘要

An apparatus comprising an oscillation blade device and a method for operating the oscillation blade device are disclosed. The apparatus comprises a power source coupled and a current meter. The power source is configured to apply a plurality of alternating electric excitation signals to an oscillation blade device at a corresponding plurality of excitation frequencies. The current meter is configured to measure the current value supplied by the power source to the driver at each one of the excitation frequencies, and provide a plurality of measured current values such that each measured current value corresponds to at least one respective oscillation frequency from said plurality of oscillation frequencies. A system comprising the apparatus is also disclosed.
