April 11: Robert Haig Weitbrecht (1920-1983)

[Image description: black-and-white photo of Robert Weitbrecht, seated, pointing to his TTY and showing it to a man leaning in to see.]

The inventor of the TTY modem (telephone typewriter, now known as TDD), Robert Weitbrecht, was born on this date in 1920, in Orange, California. Weitbrecht, deaf from birth and an astronomer by training, was a ham radio operator in the 1940s--so he had the personal interest and technical expertise to devise alternative ways to communicate electronically, long before texting or twitter or anysuch.

In his memory, TDI has a biennial Robert H. Weitbrecht Telecommunications Access Award to "the indivudual who has made outstanding contributions by any means to improve accessibility to telecommunications and media in the United States."

The word "shanzhai" is very popular in China. It is industry phenomenon of imitation, high quality and low price. Moreover, cell phones are the representative of them.The global financial crisis led to a significant shrinkage of assets for people. "china wholesale" demonstrate the might. most of them would like buy the cheap cell phones now .

Through google search engine, when you put in "discount cell phones", you will find more than 15,000 pieces of related information. Cell phone china has been concerned in the world. Many international sellers can get a considerable profit by ways of wholesale cell phones from China and switch selling. So it is a very good job on cell phones wholesale in the current financial crisis.
