摘要： An array of 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. The skew can be at least approximately linearized by distributing the clock signal in a diagonal fashion across an array of buffers corresponding to ultrasonic transducer controllers. Potential error in beam steering that can arise from clock skew can be corrected based on the linear tilt.
摘要翻译：可以控制一组超声换能器以产生可转向的梁。光束转向可能会由于时钟信号分布中的缓冲区延迟而偏移。通过在对应于超声换能器控制器的缓冲器阵列上以对角线方式分配时钟信号，可以至少近似地线性化偏斜。可以根据线性倾斜来纠正由时钟偏移引起的波束转向中的电位误差。

摘要： An ultrasonic transducer having a membrane and a container having a base and at least one wall element. The one or more wall elements can be situated over at least part of the base to form a cavity that can have an at least partially open end. The open end can be sealed with the membrane and the interior of the container can be maintained at a lower atmospheric pressure than the ambient pressure. Within the container, a piezoelectric flexure can be fixed at one end to a location at a wall element. The other end of the flexure can be in mechanical communication with the membrane, either directly or through a stiffener that is itself in communication with the membrane.

摘要： 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. The first processor can send portions of the control signal to a plurality of second processors. Each of the plurality of second processors can have a number of input lines less than the number of output lines of the first processor. Portions of the control signal can be sent through the output lines of the first processor to the plurality of second processors at substantially the same time.
