Big Al is the name we gave to the new Pentium System

This image shows a close-up of the "feedback control" screen on Big Al. The operator selects the paprameters to be shown to the subject. Controls are also shown for auditory tones, a metronome and recorded "voice" instructions.

Autogenic Clinical/Lab System (ACLS): A PC-based physiological monitoring and training system which includes an i586 processor with a 16-bit analog-to-digital converter and a multiple video display adapter (4 monitors) that utilizes software applications in the Windows 95 operating system environment. The user-interactive software can directly measure and display physiological responses in real-time. Further, realtime calculations enable non-invasive measures of cardiovascular dynamics (e.g., cardiac output, blood pressure, vagal tone, and total peripheral resistance).
