IMICRO

In 1950 they introduced the IMICRO, a 3-contact bore gauge with an innovative design, which they digitalised in 1998.[https://web.archive.org/web/20180616221621/http://tesatechnology.com/en-gb/about-us/history],Company home page about its history (retrieved 2018-06-16)

The IMICRO has a cone with a spiral to drive the 3 measurement pins outwards by rotation. This gives a higher precision than a conventional cone.[http://www.tesatechnology.com/media/497673/TESA-IMICRO-EN.pdf], IMICRO sales PDF
