Abstract: A non-invasive system and process for projecting sensory data onto the human neural cortex is provided. The system includes a primary transducer array and a secondary transducer array. The primary transducer array acts as a coherent signal source, and the secondary transducer array acts as a controllable diffraction pattern that focuses energy onto the neural cortex in a desired pattern. In addition, the pattern of energy is constructed such that each portion projected into the neural cortex may be individually pulsed at low frequency. This low frequency pulsing is formed by controlling the phase differences between the emitted energy of the elements of primary and secondary transducer arrays.

Abstract: An actuator component for a piezoelectrically-driven microatomizer comprises a diaphragm formed in a semiconductor substrate, a piezoelectric actuator which is arranged on a surface of the diaphragm and by means of which the diaphragm can be caused to vibrate, and a passage formed in the semiconductor substrate and used for supplying a liquid to be atomized from an inlet end to the diaphragm surface located opposite the piezoelectric actuator.
