Latest Patents

Ming Zhang's latest patents include a "Device and synchronous method for supplying power to an ultrasound transducer." This invention involves a method and circuit designed to drive and supply power to ultrasonic transducers using a synchronous switched capacity, which is controlled by a digital loop. The circuit features a power interface that is managed by a multi-level square or rectangular signal generator. Additionally, the device incorporates a tuning circuit that is regulated by a tuning control circuit to achieve a specific natural frequency in conjunction with the transducer. This tuning typically involves an inductor in series at the input and a controlled connection capacitor in parallel with the transducer at the output. The connection is adjusted based on a detected phase difference between the input and output of the inductor, ideally providing a phase difference equal to π/2. Furthermore, the patent describes an ultrasonic element, an ultrasonic head, and an ultrasonic imaging and/or processing system, particularly for medical applications.
