Signtel’s Sign Language Public Address and Emergency System®

As President of Signtel Inc., Raanan Liebermann has spent more than 25 years creating and developing technology to assist people who are deaf, hearing impaired, hard of hearing, deaf-blind and deaf low vision. Heading the research and development and building awareness of tools enabling an underserved community is a source of pride and drive for the soft spoken physicist. Inventing technology to enable access which others often take for granted is at the core of his work and his mission of utilizing intelligent innovation to elevate independence for every person irrespective of ability propels his purpose.

Signtel’s Sign Language Public Address and Emergency System is a necessary innovative technology. It functions to help bridge between understanding an alert, a speech, an address and idiomatic language often utilized throughout its presentation. The ability to understand spoken and written speech often relies on processing language which is reliant on common idioms and phrases not directly translatable into sign language. People who use sign language to communicate therefore find themselves vulnerable to missing portions of what they see/hear as literal meanings of the words and phrases are not helpful in understanding. The resulting confusion begs for a solution as it interferes and causes misunderstanding where comprehension is paramount and necessary.

Like preceding patented innovations of Dr. Liebermann the patented technology behind Signtel’s Public Address and Emergency System is vital to this community of potential users. The product works through utilizing all the company’s Sign Language Interpreter Software features. Its ability to translate more than 30,000 words and more than 1400 idioms and phrases along with numerical systems of time, date and money brings a new level of access to understanding colloquial speech. Users communicate through either typing text or speech recognition and the system then translates the content into a sign language video. For people with hearing impairment this system helps alert and warn them in case of emergency in the same way as their hearing counterparts are alerted.

The First Invented Laptop with Two Operating Systems

President and founder of Signtel Inc, Raanan Liebermann, is an Oxford educated physicist who envisioned software and technology possibilities before it became current and trendy to do so. Long before the start up world erupted globally and entrepreneurs evolved from wishful thinkers into success stories in what appeared to be almost an instant, Dr. Liebermann earned his Ph.D. at Oxford University and breathed possibility into a landscape of technology far before its time and long before the world would be ready to receive it.

After receiving his doctorate in astrophysics and taking on a professorship at Federal University of Pernambuco in Recife Brazil, Dr. Liebermann debated whether to accept a position at the esteemed Los Alamos National Laboratory in New Mexico in Southwestern US. Ultimately opting instead to come to the US and join Yale University in Connecticut he eventually leaned into designing breakthrough technology which would widen the scope of access in our lives.

A vision into future needs both business and personal would continue to fuel a unique understanding of ways people use day to day tools. Ultimately Dr. Liebermann would invent technologies whose software would harness efficiency and intelligence as he paved the road to today’s blossoming artificial intelligence infrastructure surrounding modern innovation. As his foresight and 27 patents showcase, life as we live it is often a base for improvement. What we do gives way to what we aspire toward and what we see in our minds eye often becomes a seed of ingenuity.

In early 1980 working along with engineers Wolf and Crowley, Dr. Liebermann designed and patented the world’s first dual processing laptop computer. Enabling two distinct operating systems to communicate for the first time, he called the compact and efficient laptop “Panda” for two reasons: Cute as a reference to its namesake and second because they eat Apples. The pun was intentional and an inside joke. This innovative laptop came to be through an instinctive understanding of needs not yet recognized and resolved; a world view that would continue to guide Dr. Liebermann’s inventive work.

As luck would have it, securing financing in early 1980 was not the world of today and not every financier is equally equipped to understand consumer behavior. As a now infamous response declared “Why would anyone need a laptop when there is a computer on every desk?” It is perhaps not coincidental that the professional world at the time was characterized by loyalty to firm and designing technology albeit necessary and game changing was a small ebb in the flow of an environment rewarding decades of loyal workers in one role companies.

The time at Oxford nurtured a core curiosity and an imagination which would translate passion to possibility. At a research university whose students are given ample room to find areas of exploration the innate wonder of what the future could hold found itself an eager student. As his work would pick up where his degree gave promise, Dr. Liebermann would find solutions to daily situations around which we are accustomed to navigate; giving them home in innovation previously unknown, often dismissed as wonder and very much ahead of their time.

The Signtel Interpreter®

After earning a Ph.D in astrophysics at the University of Oxford, Dr. Raanan Liebermann has continued to  contribute to the scientific community through breakthrough technology innovation. Raanan  Liebermann is the creator and founder of Signtel Inc., a Connecticut based tech company that designs  revolutionary technologies to assist people with hearing and visual impairments in daily life. Electronic  Canes with sensory perception to communication capabilities, television which blind persons can watch,  and a communication device for the deaf with the first simultaneous speech to text technology are  among the breadth of Dr. Liebermann’s inspired technology. 

Signtel Inc. is named for its base invention, the Signtel Interpreter®. Dr. Liebermann designed this  original software to transform the way deaf and hearing persons communicate. The software is a revolutionary innovative technology introduced to assist in situations where an ASL sign language  

interpreter is not available. It utilizes technology in lieu of a live interpreter to bring independent access  to the hearing impaired; introducing the ability to transcribe speech to text and vice versa in real time  for necessary mutual understanding. It presented the capacity of a new tool to bridge a communication  gap between hearing and hearing – challenged communities; easing an often cumbersome process  reliant on the teletypewriter (TTY). 

The Americans with Disabilities Act of 1990 brought protection against discrimination of access. It brought awareness of the need for tools among public institutions to the forefront of daily life. It  became necessary for schools, hospitals and government offices to enable and accommodate access to  every person equally. Wheelchair accessible entrances and building elevators became a necessity. This  unprecedented act presented a gateway for progress; aiding underserved sections of society.  Technology as a tool for access became a center of new and inspired innovation. It enabled increased  resources such as the Signtel Interepreter® and gave momentum to the technological innovation which  ensued on its heels. 

At its core, Signtel and its inherent innovation is the brainchild of Dr. Liebermann and shares its essence  with its founder. Dr. Liebermann’s visionary technologies originate with an encompassing desire to use  his ability to create and design solutions for the underserved. The skill of creating pathways to societal  progress is born of his desire to improve quality of life and connect people to society and each other.  Like the Signtel Interpreter®, Dr. Liebermann’s technology is built on a foundation of his core belief: each person deserves equal access to resources and a standard of living reliant on choice and not on  sensory abilities.

About a passion project evolving out of a personal interest and a scientific mind. Combined and woven  into a desire to help others.

A Passion Project

In a regular visit to a local health store Dr. Liebermann noticed a flyer advertising an upcoming lecture.  The small store would often share workshops and speakers whose work in areas of health and wellness  found intrigue in the community. “Hi Ron!” called the store owner to Dr. Liebermann. “A great speaker” 

he said nodding toward the flyer and walked toward him to chat. As usual in his community, Dr.  Liebermann’s known friendliness, ready story and often a joke, would bring conversation and mutual  interest alongside his varied interests and scientific acumen. “I always learn something” his doctors  would say with a smile and understanding of the curiosity infused discussion. Dr. Liebermann would  gratefully respond “solutions come when strong minds think together”. 

This motto is as much style as it is representative of substance. Raanan Liebermann often shares this  inquisitive based search for solution oriented thinking in a wide array of conversation whether personal,  business or an innovative space merging between the two. It is not unusual to find inspiration in a  question someone poses which causes his own thinking and soon thereafter application to whichever  area he has taken on learning. With a Ph.D. in astrophysics it is perhaps not unusual to find stimulation  in academic consideration and stretching the palette of what is known. 

Raanan Liebermann is the President of Signtel Inc., which uses artificial intelligence to design and create  technology for deaf/blind persons. The company is based on Dr. Liebermann’s innate interest to help  ease the lives of persons with disabilities. A natural offshoot of this driving motivation is his personal  interest in medical research and easing the burdens of people whose wellbeing is affected. 

A believer of asking questions as the strongest indicator of a thorough answer Dr. Liebermann’s probing  curiosity is as much his modus operandi as it fuels his encouragement of those around him to pursue  research and stretch thinking toward new findings and their application. As we learn we think and when  we think we inspire ourselves further is his repurposed adage of the time old “which came first” between chicken and egg ponderance. A scientist first and foremost, this inclination to study and  question before theorizing and applying possible solutions is as much a tool of understanding the world  as it is his natural wiring. As much a lifestyle as his education. And it serves his professional and personal  interests on a daily basis. Student as much as teacher Dr. Liebermann believes in science as a way of life,  a method of absorbing the intricacies of our understanding and combining the two into the grandest  unknown of all: future possibilities. 

Long an academic with a passion for innerworkings of people, Dr. Liebermann’s lean toward innovation  lends itself to an interest in cognitive understanding of nourishment and the body’s instinctive and  capable restoration of its health and cadence. Utilizing ongoing research both medical and theoretical  and an ability to synthesize and question findings in medical journals, Dr. Liebermann combines curiosity  about foods to build natural disease resistant resources as he taps into techniques enabling the body to 

resolve difficulties in tactile and accessible ways. In applying research and its synthesis to cater to a  person’s individual needs, Dr. Liebermann’s investment is both meaningful and necessary. 

What began as a theoretical curiosity and self-oriented inquiry soon evolved into a passion project. As  members of his family and eventually friends, colleagues and his own doctors would find, the practical  and precocious repurposing of foods and their combinations would bring Dr. Liebermann initial  skepticism before enough cautious curiosity to ask their own doctors’ permission to try his suggestions  and eventually wide eyed gratitude at their results and relief. 

It is in this way that Raanan Liebermann resolved his own arthritic hand pains and began to take great  care in what he ingested and why. Actions as elementary as a family dinner began to be prefaced by a  series of intake questions surrounding amounts of garlic used, presence of sugar and other variations of  ingredients which lent themselves to necessary consideration. The alkaline nature of lemons and their  host of preventative properties would soon begin each day; inclusive of zest to juice. The ph scale of foods in their natural state would become as much a reference as the scientific periodic table of the  elements. It is a pure bonus that as a scientist Dr. Liebermann’s innate love of food is as much  omnipresent in his endeavors to understand chemistry of cause and effect as his penchant to apply his  learnings. 

Professionally, the constructive foundation of a company built to help the under acknowledged connects  easily to a hobby of personal interest. Born of a desire to increase and ease people’s wellbeing Dr.  Liebermann uses a natural ability to research and identify collaborative elements to affect health in a  sphere of foods and natural resources. It is truly a passion project. Such a thorough and analytical  application is a natural continuation of professional achievement of working to bring innovative tools to  the underserved. This desire to ease burdens for others – through technology solutions and natural  resources results in an intriguing merge of business and personal worlds. 

With keeping the body in as much its optimal functioning mode as possible and its inherent disease  prevention, Dr. Liebermann’s interest also focuses on application of potentially supportive treatments  alongside guidance of medical professionals. Building on a curiosity sewn of an interest in medical school  courses preceding his doctorate in astrophysics he takes learning seriously and the academic challenge  is welcome: understanding and applying natural foods and resources to see whether it could be possible  to stabilize the body and its possible disease difficulty through recalibrating whichever area is affected. Always with a thoughtful instruction to whoever is asking to absolutely consult with the physician in  charge.  

Between his understanding of nutrients and their natural chemical properties, an ability to identify  potential resources to ease a situation and a whole hearted desire to enable a person to feel strong and  whole, Dr. Liebermann’s passion project has earned him eager ears and note takers. With a connection 

to people at his core, this is perhaps the most significant motivator for his contribution. A close second is  the ever present academic appetite to learn and disseminate knowledge wherever possible. 

As friends tell friends and his own doctors listen to his desire to consult in his own care the little passion  project evolved. Whether utilizing foods in various elements, factoring in time for optimal oxygenation, inherent spice properties, tea and intentional combinations to enable bio available properties of  whichever nutrient he would like to activate, word of mouth brings people to ask for his advice as much  as he loves sharing it. As he speaks and consults with his doctors and encourages others to consult with  their own, possible ideas continue to emerge which lean more on nature and less on medicine. As  western medicine so often proclaims of itself as being reactive rather than preventative, finding new  avenues to prevent problems and progress health is itself a win.  

To combine a scientific mind with a channel often kept clinical and reactive is eye opening as is a consideration of bringing theoretical application to the forefront of treatment. Always alongside  traditional practice but as every science asks of itself, evolution is the goal; the process is merely where  ideas navigate. 

Built on Hippocrates’ belief of “let food be thy medicine” and working in tandem with medical  practitioners widens each scope of consideration and brings an academic element to stretch established  practices. Often sharing insight and arming friends and colleagues with directive questions to ask their  own doctors is as rewarding as it is stimulating. Both in use of preventative care, clinical visits and  recuperation of a person’s unique situation the vibrant collective conversation often results in a broader perspective.

Signtel’s Public Address and Emergency Alert System Improves Safety

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.

Distinctive Features of the Signtel Interpreter

Technology entrepreneur Raanan Liebermann has authored various technical publications and holds close to 10 patents. A resident of North Haven, Connecticut, Raanan Liebermann is the president of Signtel, Inc., a North Haven, Connecticut-based company that develops and sells products for people who are deaf, blind, or both. One of Signtel’s goals is to make communication easier between people who can hear and those who cannot. One of its flagship products is the Signtel Interpreter, a patented software that can translate text and speech into sign language with the help of artificial intelligence. The interpreter recognizes 30,000 English words and 1,400 idioms and phrases, connecting people who can hear with those who cannot. Besides its expansive vocabulary of recognizable terms, the Signtel Interpreter has many more features that set it apart. For example, it is the only interpreter that provides seamless connectivity between signs. It contextually differentiates between words that have several meanings and provides the correct sign interpretation and can fingerspell names such as Mr. Brown and Mr. Stone, differentiating them from the color brown or the object stone. The interpreter also has forced fingerspelling for difficult words and supports two-way recognition thanks to state-of-the-art speech recognition technology and a built-in lip reader.

Touch Language – Basics

An alumnus of University of Oxford in the U.K., Raanan Liebermann is the president of Signtel, Inc., located in North Haven, Connecticut. The company works on various assistive technologies for people with visual and hearing challenges. Among many other projects, Raanan Liebermann also created the Touch Language. Here’s more on this innovative language.

Instead of relying on grammar, Touch Language relies on concepts. The fact that the users can articulate these concepts by positioning their fingers and hands makes this language universal, independent of the locally spoken language.

To communicate via Touch Language, the users need special electronic gloves. The gloves vibrate and peck in particular areas of the hands and fingers to denote various concepts. For example, time adverbs are located on the distal phalanx of the little finger. Adverbs and noun modifiers are on the intermediate phalanx of the ring finger, while affirmation and negation areas are near the wrist. This language is in the public domain, despite being patented to prevent any possible changes and modifications by a third party user. Any modifications will have to be approved by the World Touch Language Forum. Touch Language can be downloaded free of charge from the Signtel, Inc. website at: www.signtelinc.com.

How Technology Can Be Used to Combat Climate Change

An accomplished artificial intelligent innovator and a member of the academia, Raanan Liebermann is a long-time career professional and president of Signtel, Inc., a company he has headed for close to two decades. In addition, Raanan Liebermann has innovations that include Crowd-Sourced Clean Energy which aim is to utilize technology in combating climate change.

The threat of climate change is evident with the rapid increase of the global population, higher demand for food, and land and energy use. For this reason, climate scientists and other key stakeholders are increasingly voicing the need to utilize technology to help combat the effects of climate change using some of the techniques below.

1. Embrace the use of mobile apps that can help to effectively monitor and reduce carbon footprint and waste. There are some apps that track carbon footprint when traveling while others place a carbon value on everything that is purchased and consumed.

2. Clean energy is one of the most challenging issues to handle but technology can help to build a smarter energy grid which helps in the storage and transmission of energy once it’s captured.

3. Technology can help create livable cities by tech firms spearheading the transition to halve city emissions within the next decade or less and providing tools to help monitor emissions and reduce them.

4. Switching to plant-based meat replacements considering the livestock industry is a great contributor to climate change. Technology has made it easier to cut out animal-based foods.

The Crowd-Sourced Clean Energy is a paradigm shift new technology that turns around major polluting sources into generators of clean energy.

Touch Language Creates New Possibilities for the Blind/Deaf and Blind

Serving Signtel Inc. as president since 2000, research and development specialist Raanan Liebermann has performed several extensive studies that resulted in innovations that offer new possibilities for people with special needs. For instance, Raanan Liebermann has patented his developed Touch Language, a new technology that benefits the blind and the deaf and blind.

Touch Language is a new language based on concepts rather than vocabulary or grammar. The concepts are identified by portions of the hands and fingers, making Touch Language a universal language – that is, it allows the user to communicate regardless of his or her culture or native language. Although the user will need time to learn Touch Language, the rewards make the effort worthwhile.

Designed to help the blind and the deaf and blind to communicate, Touch Language lets the user wear electronic gloves that allow communication through pecking and vibrations on the hands and fingers. Although Touch Language is still being incorporated into TV broadcasting, once it is fully implemented, Touch Language will also allow the blind and the deaf and blind to enjoy TV broadcasts.

Although Touch Language utility for TV is in the public domain that may be downloaded and studied at anytime, its creator has patented the product to protect its integrity. The patent will guarantee users that no partisan modifications will be made to the product that might confuse them. Any changes to the language will need to be approved by the World Touch Language Forum, which is expected to be in operation soon.
