For the past 20 years, Raanan Liebermann has served as president of Signtel, Inc., a North Haven, Connecticut-based company that creates innovative products for people who are deaf and blind. In addition to patented products such as Telephone for the Deaf and an electronic cane, Raanan Liebermann and Signtel that partnered with FEMA on the national Emergency Alert System developed a patented inclusive Public Address and Emergency Alert System. In a world where natural disasters and terrorist attacks are increasingly common, public alert systems need to be equipped to reach all people. Installed in public spaces such as schools, malls, bus stations, train stations and airports, the Emergency Alert System allows deaf and/or blind people to become aware of any publicly broadcast alert.
People who are deaf can view the alert on a screen, while people who are blind receive vibratory alerts on an eCane. The system utilizes the same technology as the Signtel Interpreter translation engine, which means it can translate over 30,000 words and over 1,400 idioms and phrases, as well as numerical systems. To date, the system has been successfully installed in public spaces including the Horace Mann School for the Deaf, a member of the Boston public school system.
