Our engineer became aware that users of Talking Book Machines often fell asleep (or had a phone call or other interruption ) while listening to books and magazines. The tape continued playing, losing the listener's place. He developed a switch and 6' long cord, which plugs into the existing remote control port on the tape player (marked REM) and interrupts the power unless our momentary dead man switch is held down. As users begin to doze off, they relax, release pressure on the switch and the recording pauses at that point - in effect, creating a bookmark. To resume listening, it is a simple matter to rewind a short distance and pick up the recording where it left off. Especially useful when following instructions or recipes, for students, or anyone who relaxes by listening to talking books.
