Portable computer ultrasonic data acquisition system

摘要

A circuit board (6) having a Type II PC form factor includes a receiver interface (28) for interfacing a receiver signal (18) from an ultrasonic transducer (10) and producing a received signal therefrom; an analog-to-digital converter (32) for converting the received signal to a plurality of digital signals; a first-in, first-out memory (36) for storing the digital signals; a control circuit (40) at least for controlling transfer of the digital signals from the A/D converter (32) to the FIFO memory (36); and a memory interface circuit (38) for interfacing the FIFO memory (36) with a portable computer (4).
