With a total of three patents to his name, Vassallo's work focuses on enhancing the capabilities of biometric imaging and identity verification systems.
Latest Patents
One of Vassallo's latest patents is an ultrasonic biometric imaging and identity verification system. This innovative system includes a probe with a platen that supports human or animal tissue for imaging. A transducer is positioned closely adjacent to the platen, providing an output ultrasonic beam directed at the surface. The design aims to maximize resolution by minimizing the size of the beam at its focal point. The system features an electrically operated motor that moves the transducer, directing the ultrasonic beam along the surface. Additionally, a fluid-tight housing contains the transducer and motor, filled with an electrically non-conductive fluid that has an acoustic impedance similar to water. The housing is equipped with a bellows to accommodate thermal expansion and contraction of the fluid. The motor provides oscillatory output motion, and an encoder is mounted on the shaft to minimize distortion in the information provided. The coupling is designed to maintain rigidity while minimizing drag as it moves through the fluid.
