Astro-Med Announces Powerful New Software Package.

WEST WARWICK, R.I. -- The Grass-Telefactor product group of Astro-Med, Inc. (NASDAQ:ALOT), announces TWin(R) version 3.5, a powerful, feature-filled Windows-based software package, which provides increased acquisition and review functionality for Grass-Telefactor EEG, PSG (sleep), and Long-term Monitoring (Epilepsy) systems.

Typical applications for the new software include the recently announced AURA24(TM) ambulatory EEG, a compact, light weight recorder that a patient can wear home for overnight EEG monitoring. In this application, the new software facilitates recording, review, analysis and report generation of data by the AURA24. TWin 3.5 also supports the new Grass-Telefactor SleepTrek(TM) ambulatory sleep screener for use in overnight studies in the home. Both the AURA24 and the SleepTrek portable systems expand the Grass-Telefactor clinical product offering for monitoring and diagnosing epilepsy and sleep disorders.

The recently announced FASS software program by Grass-Telefactor for automatically scoring stages of sleep, thereby increasing the productivity of sleep labs, is also fully supported by the new software.

TWin 3.5 delivers important new features to the Sleep market, such as .EDF (European Data Format) capability, which allows TWin 3.5 to export files in .EDF, and import files recorded on other systems with the .EDF format. Another significant feature of the new software is its easy-to-interpret final report on the sleep study, often referred to as the "timeline" or "hypnogram". The report presents the results of the sleep study in a format that helps expedite the final decision process by the physician.

Complementing the new software is a powerful, integrated search and query database manager that tracks patient and study information, as well as sleep report statistics. The query feature produces reports showing patient demographics and diagnosis results. The database is extremely versatile, and allows for easy customization by the end user.

The Grass-Telefactor Product Group of Astro-Med designs, manufactures, and sells advanced systems for EEG and PSG (sleep monitoring), Long-term Epilepsy monitoring, and OR/ICU neuromonitoring, as well as supplies, accessories, and a broad range of products for neurophysiological research.

Grass-Telefactor's new TWin 3.5 software is now available from stock. Visit Astro-Med, Inc. at www.grass-telefactor.com for further information.
