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.
Celesta
The celesta was invented in 1886 by the Parisian harmonium builder Auguste Mustel. His father, Victor Mustel, had developed the forerunner of the celesta, the typophone, in 1860. This instrument produced sound by striking tuning forks instead of the metal plates that would be used in the celesta. The dulcitone functioned identically to the typophone and was developed concurrently in Scotland; it is unclear whether their creators were aware of one another's instrument. The typophone/dulcitone's uses were limited by its low volume, too quiet to be heard in a full orchestra.
