The Grass-Telefactor Product Group of [West Warwick-based] Astro-Med Inc. announced in a release that it has “cut the cord” on its Comet and AURA series amplifier systems.

Traditionally, EEG recording consists of an amplifier, power supply, PC and other components all on a rolling cabinet. Now, using wireless technology, the small Grass-Telefactor amplifier sits near the patient, without a physical connection to the PC.
