Function

TO ANALYSE PATIENT DATA RECORDING SLEEP PATTERNS, IN ORDER TO PERFORM SUBSEQUENT RESEARCH.

Technical

PRIOR TO THE DEVELOPMENT OF THIS AUTOMATIC APPARATUS, RECOGNITION OF THE ONSET OF VARIOUS SLEEP PATTERNS HAS TO BE DONE BY THE VISUAL INSPECTION OF THE GRAPHIC OUTPUTS OF SENSORS THAT HAD BEEN ATTACHED TO THE PATIENT'S HEAD & EYES. THIS TIME-CONSUMING PROCESS REQUIRED SCANNING HUNDREDS OF PAGES OF GRAPHIC OUTPUT CONTAINING UP TO 6 OR 8 PEN RECORDINGS ON THE GRAPHS. DATA COLLECTED ON THIS UNIT WAS STORED ON CASSETTE TAPES: 24HRS OF DATA TOOK ONLY 72 MINS. TO PLAY BACK. IT COULD COLLECT DATA FROM SLEEPING PATIENTS IN LAB, OR EXAMINE DATA COLLECTED BY 4-CHANNEL PORTABLE RECORDING SYSTEM.
