Dacom Industry and Data Compression Founded 1966 Founder Daniel Hochman and Donald Weber HeadquartersUSA Area served Global Products Dacom Rapidfax 100, Dacom DFC-10, Dacom 111 Receiver, Dacom 212, Rapidfax 412 Dacom, Inc.
Their work resulted in the dacom electronics commercial machine and later the first sub-minute facsimile transmission over a single standard phone line.
The patents and technology developed by Dacom dacom electronics become the foundation of the modern desktop fax machine.
In 1959 Hochman's team at Lockheed unveiled a 9-pound miniature television system that could http://slot-promo.win/games-for/games-for-toddlers-at-home.html pictures from as far as 1000 miles in space, and in the early 1960s was working to develop a high-speed communications system for the transmission dacom electronics images from space.
The team faced two related problems: the density of data of a high-resolution photograph, and the low-power, low-capacity transmitters on board satellites.
To address these problems, Hochman brought in Donald Weber to work on the problem of data compression - to achieve a higher rate of data transmitted with the same low-power equipment.
In 1966 Hochman and Weber realized the potential application of the technology they had invented to create a digital facsimile machine, capable of transmitting images over a standard phone line in considerably less time than the then-current state-of-the-art analog facsimile machines offered by, and Stewart Warner.
They left Lockheed to form their own company: Dacom free train toddlers games for stood for Data Compression.
The first systems were models DFC-10 and the Dacom 111, which came to market in the late 1960s.
Hochman and Weber presented Dacom's data compression technology at the dacom electronics International Conference on Communications in a paper which has been since cited as a seminal work in the field of image digitization and data compression.
The company was awarded a number of patents that constitute the foundation of modern data compression and facsimile transmission see table below.
Savin was a major distributor of products at the time.
The joint venture resulted in the creation of Rapifax Company, which purchased a majority interest in Dacom and was responsible for marketing Dacom products.
The Dacom 412 Secure Fax, the first digital sub-minute facsimile came to market shortly after and in 1973 was awarded the IR-100 Best Product of the Year award.
Also, in 1973 a majority interest in Rapifax was sold to Ricoh, a Japanese manufacturing company, which purchased the CBS holdings in the company.
Dacom became a wholly owned subsidiary of Rapifax and its technology was transferred to the parent company.
Savin retained a dacom electronics in Rapifax, which was subsequently sold to Ricoh as well.
Dacom technology was ultimately incorporated into the Ricoh brand fax machines.
In the mid-1970s, the Rapifax 100 established itself as the market leader in the "ultrafast facsimile market".
