"This paper presents the design and realization of optical communication interface. It improves communication between people in very noisy environments, where conventional voice communication is unusable. Secondary function of the device is to count the number of uses. One of the design requirements was to use original Tesla semiconductors." . . "Optical communication, LED display, Tesla, TTL."@en . . . . "978-80-214-4579-6" . "[5FC0044DAD9E]" .
