Ultrasonic Transducer Control
First Claim
1. A system, comprising:
- a first controller having 8 available first controller output lines comprising a first subset of 4 first controller output lines;
a second controller having 4 second controller input lines and 16 second controller output lines, the 16 second controller output lines electrically connected to a first set of ultrasonic transducers;
the first controller adapted and configured to receive a 16-bit ultrasonic transducer control signal, separate the 16-bit ultrasonic transducer control signal into four 4-bit intermediate ultrasonic transducer control signals and send each of the 4-bit intermediate ultrasonic transducer control signals to the second controller through the first subset of 4 output lines; and
the second controller adapted and configured to receive each of the four 4-bit intermediate ultrasonic transducer control signals through the 4 second controller input lines, to reassemble the 16 bit ultrasonic transducer control signal based on the received four 4-bit intermediate ultrasonic transducer control signals and to send the 16-bit ultrasonic transducer control signal through the 16 second controller output lines to the first set of ultrasonic transducers.

Abstract
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.
