The cleaning is performed by using a system such as a transducer assembly including at least one pair of protrusions acting as point-like pressure sources or at least one substantially circular protrusion acting as a substantially circular point-like pressure source, coupled to outer surface of the device to be cleaned. Accordingly, coupling of the system to device is reduced, and as a result, the system is able to operate at its fundamental resonance frequency, while the protrusions still permit power delivery to the device.

Abstract: A system for measuring pressure of an eye includes an excitation source for producing a travelling air vortex ring and for directing the travelling air vortex ring to the eye, a detector for detecting an interaction between the travelling air vortex ring and a surface of the eye, and a processing device for determining an estimate of the pressure of the eye based on the detected interaction between the travelling air vortex ring and the surface of the eye. The travelling air vortex ring is produced by directing an air pressure pulse into a flow guide, and the air pressure pulse is generated with an electric spark or otherwise so that no swinging mass, such as a piston, is needed. This is advantageous especially in a case of a handheld device because a swinging mass would tend to adversely move the handheld device during a measurement.
