Aquapac
Aquapac is a registered trademark and brand name of a UK-based manufacturing company, Aquapac International Limited, specializing in waterproof cases and bags. The privately owned company was formed in 1983 and holds patents worldwide on systems for sealing bags and cases. The range commenced with a waterproof case for the original Sony Walkman known as the ‘Aquaman’, followed by cases for handheld VHF radios. Following Motorola’s invention of the first cellphone Aquapac launched the world’s first waterproof cellphone case. Nokia was an important customer for these cases during the 1990s, as were cellphone operators such as Deutsche Telekom and NTT DoCoMo. Aquapac went on to launch waterproof cases for other handheld electronics such as cameras and eReaders. The company operates out of factories in London, England.
Invention of the telephone
Alexander Graham Bell had pioneered a system called visible speech, developed by his father, to teach deaf children. In 1872 Bell founded a school in Boston to train teachers of the deaf. The school subsequently became part of Boston University, where Bell was appointed professor of vocal physiology in 1873. He became a naturalised U.S. citizen in 1882.
Bell had long been fascinated by the idea of transmitting speech, and by 1875 had come up with a simple receiver that could turn electricity into sound. Others were working along the same lines, including an Italian-American Antonio Meucci, and debate continues as to who should be credited with inventing the telephone. However, Bell was granted a patent for the telephone on 7 March 1876 and it developed quickly. Within a year the first telephone exchange was built in Connecticut and the Bell Telephone Company was created in 1877, with Bell the owner of a third of the shares, quickly making him a wealthy man.
In 1880, Bell was awarded the French Volta Prize for his invention and with the money, founded the Volta Laboratory in Washington, where he continued experiments in communication, in medical research, and in techniques for teaching speech to the deaf, working with Helen Keller among others. In 1885 he acquired land in Nova Scotia and established a summer home there where he continued experiments, particularly in the field of aviation.
In 1888, Bell was one of the founding members of the National Geographic Society, and served as its president from 1896 to 1904, also helping to establish its journal.
Bell died on 2 August 1922 at his home in Nova Scotia.
