Galina: Legacy Assistive Tech

A contactless material-level indicator for the blind and visually impaired.

Galina is a compact, contactless device that helps blind and visually impaired individuals pour liquids or dry materials safely into any container. It uses real-time distance sensing to detect rising levels and provides intuitive audio or vibration feedback to prevent over-pouring—ensuring greater independence and ease in daily tasks.

Galina's Origin Story

Nir and Ron Pechuk, Extentek™ CEO and CTO, were visiting their grandmother, Galina. In the evening, she asked one of them to pour a cup of tea for her explaining that she does not see well in darkness and usually over pours. The following night, they paid attention that every time their grandmother needed to pour water when the light was not bright, she would use her finger to know when to stop.

Initially using Lego and Arduino, they developed a primitive device that was supposed to be placed near the cup and beep when the cup is full. This was the first prototype of Galina™, a contactless material level indication device that helps blind and visually impaired to prevent spills. 

Later on, the boys met Maxwell Mamishev, Extentek™ CINO who improved Galina™ using smaller sensors and faster technological processes to build the device as well as feedback from dozens of visually-impared users.

Galina is protected under U.S. Patent No. 10,830,626 (US10830626B2), recognizing its unique, contactless liquid level detection technology.

We are no longer selling Galina directly, but are continuing to develop next-generation variants and exploring integrations with borader systems.
