Abstract (en)
[origin: WO2014143942A2] An ultrasonic transducer having a membrane and a container having a base and at least one wall element. The ultrasonic transducer can include a driver side and a bias voltage side. A first controller can have a greater number of output lines than a second controller has input lines. The first controller can receive an ultrasonic transducer control signal and provide a first portion of the control signal to the first processor, where the length of the first portion is less than or equal to the number of input lines of the second processor. An array of the ultrasonic transducers can be controlled to produce a steerable beam. Beam steering can be skewed by buffer delays in the distribution of a clock signal.
