A Phone of Our Own

The Deaf Insurrection Against Ma Bell

Harry G. Lang

Gallaudet University Press, 2000

In 1964, of the more than 85 million telephones in the United States and Canada, less than one percent were used regularly by deaf people. If they didn’t ask their hearing neighbors for help, they depended upon their hearing children, some as young as three years old, to act as intermediaries for business calls or medical consultations. In that same year, three enterprising deaf men, Robert H. Weitbrecht, James C. Marsters, and Andrew Saks, started the process that led to deaf people around the world having an affordable phone system that they could use.

Weitbrecht, a successful physicist with the Stanford Research Institute, had been experimenting with a teletypewriter (TTY) used with shortwave radios. When Marsters, a prominent deaf orthodontist, met Weitbrecht and saw his TTY, he immediately suggested the possibility of resolving deaf people’s decades-long struggle to have access to telecommunications without relying totally upon hearing people as go-betweens. Andrew Saks brought his business acumen to the group, which soon set to work overcoming the daunting problems they faced.

Harry G. Lang’s A Phone of Our Own: The Deaf Insurrection Against Ma Bell tells how these three men collaborated to solve the technical difficulties of developing a coupling device for TTYs that would translate sounds into discernible letters. More remarkably, and with the help of an expanding corps of Deaf advocates, they successfully assaulted the American Telephone and Telegraph Company (AT&T), which in its efforts to protect its monopoly, smashed old TTYs to keep them from being used for potentially competitive purposes. The Federal Communications Commission (FCC) also resisted efforts to build a telephone system for deaf people that was available, affordable, portable, and fully accessible. Lang recounts in vivid terms how many other Deaf individuals and groups from all walks of life joined Weitbrecht, Marsters, and Saks against these forces. A Phone of Our Own is an entertaining and engrossing story of how they fought and won, and changed the world for the better for deaf people everywhere.

Physical Layer Security for 6G Networks

Trung Q. Duong

The Institution of Engineering and Technology, 2024

6G networks are expected to provide one-microsecond latency communication with a billion of devices expected to compete for resources 1000 times faster than current standards. Increases in network speed, heterogeneity, virtualization, better radio requirements and adaptive communications will place new demands on physical layer security. Moreover, IoT, blockchain, and artificial intelligence are enabling technologies that require rapid data rates, raising a significant burden on the network's physical layer, requiring that security must be attained at a fast pace, and that the network must be resilient to accommodate sudden changes to the configurations or the load.

The Post-Screen Through Virtual Reality, Holograms and Light Projections

Where Screen Boundaries Lie

Jenna Ng

Amsterdam University Press, 2021

Screens are ubiquitous today. They display information; present image worlds; are portable; connect to mobile networks; mesmerize. However, contemporary screen media also seek to eliminate the presence of the screen and the visibilities of its boundaries. As what is image becomes increasingly indistinguishable against the viewer’s actual surroundings, this unsettling prompts re-examination about not only what is the screen, but also how the screen demarcates and what it stands for in relation to our understanding of our realities in, outside and against images. Through case studies drawn from three media technologies – Virtual Reality; holograms; and light projections – this book develops new theories of the surfaces on and spaces in which images are displayed today, interrogating critical lines between art and life; virtuality and actuality; truth and lies. What we have today is not just the contestation of the real against illusion or the unreal, but the disappearance itself of difference and a gluttony of the unreal which both connect up to current politics of distorted truth values and corrupted terms of information. The Post-Screen Through Virtual Reality, Holograms and Light Projections: Where Screen Boundaries Lie is thus about not only where the image’s borders and demarcations are established, but also the screen boundary as the instrumentation of today’s intense virtualizations that do not tell the truth. In all this, a new imagination for images emerges, with a new space for cultures of presence and absence, definitions of object and representation, and understandings of dis- and re-placement – the post-screen.

Power System Protection

Application, Volume 3

The Electricity Training Association Electricity Training Association

The Institution of Engineering and Technology, 1995

The worldwide growth in demand for electricity has forced the pace of developments in electrical power system design to meet consumer needs for reliable, secure and cheap supplies. Power system protection, as a technology essential to high quality supply, is widely recognised as a specialism of growing and often critical importance, in which power system needs and technological progress have combined to result in rapid developments in policy and practice in recent years. In the United Kingdom, the need for appropriate training in power system protection was recognised in the early 1960s with the launch of a correspondence course from which these books emerged and have since developed designed to meet the needs of protection staff throughout the world.

Powerful Frequencies

Radio, State Power, and the Cold War in Angola, 1931–2002

Marissa J. Moorman

Ohio University Press, 2019

Powerful Frequencies details the central role that radio technology and broadcasting played in the formation of colonial Portuguese Southern Africa and the postcolonial nation-state, Angola. In Intonations, Marissa J. Moorman examined the crucial relationship between music and Angolan independence during the 1960s and ’70s. Now, Moorman turns to the history of Angolan radio as an instrument for Portuguese settlers, the colonial state, African nationalists, and the postcolonial state. They all used radio to project power, while the latter employed it to challenge empire.

From the 1930s introduction of radio by settlers, to the clandestine broadcasts of guerrilla groups, to radio’s use in the Portuguese counterinsurgency strategy during the Cold War era and in developing the independent state’s national and regional voice, Powerful Frequencies narrates a history of canny listeners, committed professionals, and dissenting political movements. All of these employed radio’s peculiarities—invisibility, ephemerality, and its material effects—to transgress social, political, “physical,” and intellectual borders. Powerful Frequencies follows radio’s traces in film, literature, and music to illustrate how the technology’s sonic power—even when it made some listeners anxious and frightened—created and transformed the late colonial and independent Angolan soundscape.

Principles and Applications of Free Space Optical Communications

Arun K. Majumdar

The Institution of Engineering and Technology, 2019

Free Space Optical (FSO) Communication uses light propagation in free space (air, outer space, and vacuum) to wirelessly transmit data for telecommunications and communication networking. FSO Communication is a key wireless and high-bandwidth technology for high speed large-capacity terrestrial and aerospace communications, which is often chosen as a complement or alternative to radio frequency communication. The propagating optical wave can be influenced negatively by random atmospheric changes such as wind speed, temperature, relative humidity, and pressure, thermal expansion, earthquakes, and high-rise buildings. This edited book covers the principles, challenges, methodologies, techniques, and applications of Free Space Optical Communication for an audience of engineers, researchers, scientists, designers, and advanced students.

Principles of Performance Engineering for Telecommunication and Information Systems

M. Ghanbari

The Institution of Engineering and Technology, 1997

The term 'teletraffic engineering' has been used since the early days of the century to describe the design of switched telecommunications networks in terms of probabilities. More recent advances in queuing theory, and the growing realisation that the basic techniques can be applied to many other aspects of system design, has led to an extension of the subject and to the term 'performance engineering'.

The Hope for Democracy in the Age of Network Technology

Darin Barney

University of Chicago Press, 2000

From all sides, we hear that computer technology, with its undeniable power to disseminate information and connect individuals, holds enormous potential for a reinvigoration of political life. But will the Internet really spark a democratic revolution? And will the changes it brings be so profound that past political thought will be of little use in helping us to understand them?

In Prometheus Wired, Darin Barney debunks claims that a networked society will provide the infrastructure for a political revolution and shows that the resources we need for understanding and making sound judgments about this new technology are surprisingly close at hand. By looking to thinkers who grappled with the relationship of society and technology, such as Plato, Aristotle, Marx, and Heidegger, Barney critically examines such assertions about the character of digital networks.

Along the way, Barney offers an eye-opening history of digital networks and then explores a wide range of contemporary issues, such as electronic commerce, telecommuting, privacy, virtual community, digital surveillance, and the possibility of sovereign governance in an age of global networks. Ultimately, Barney argues that instead of placing power back in the hands of the public, a networked economy seems to exacerbate the worst features of industrial capitalism, and, in terms of the surveillance and control it exerts, reduces our political freedom.

Of vital interest to politicians, communicators, and anyone concerned about the future of democracy in the digital age, Prometheus Wired adds a provocative new voice to the debate swirling around "the Net" and the ways in which it will, or will not, change our political lives.

Propagation of Short Radio Waves

Donald E. Kerr

The Institution of Engineering and Technology, 1987

This book treats the phenomena associated with the propagation of short radio waves between terminal points, whether they be the radar antenna serving a dual purpose or the antennas of a communications system. The intention is to present a summary of the state of knowledge in the microwave propagation field at the close of the war. There has been no attempt to produce either a handbook or textbook, but only an interim report on a rapidly changing subject. An attempt has been made to survey all relevant information that was available, from whatever source, and to summarise as much of it as was feasible.
