  • Publication number: 20190196013
    Abstract: A method for ultrasound data processing comprises transmitting an ultrasound excitation signal from each element of a transducer array and receiving a response signal from each element of a transducer array. Each response signal corresponds to a respective channel. Each response signal is sampled at one or more time points in the response signal to create a plurality of samples, each sample corresponding to a channel and a time point. The samples are divided into at least two groups. Response signals from the first group are beamformed and response signals from the second group are beamformed separately. The process is repeated over multiple data frames. The beamformed signals of each group are correlated over the multiple data frames and beamformed signals having a lower degree of correlation or negative correlation are selectively attenuated. An image output is generated from the correlation output.

  • Patent number: 10170940
    Abstract: A load-independent Class EF inverter may maintain ZVS operation, and produce a constant output current, rather than a constant output voltage, regardless of the load resistance. A constant output current allows the inverter to operate efficiently for a load range from zero resistance (short circuit) to a certain maximum load resistance, making the inverter more suitable as a coil driver for an IPT system. The resonant frequency of the resonant circuit may be tuned to a non-integer multiple of a switching frequency.
