MOVEMENT-SENSITIVE DEVICE Russian patent published in 2007 - IPC G01B7/00 

FIELD: capacity type devices sensitive to displacement.

SUBSTANCE: device, sensitive to movement, contains: body (10;110); needle holder (16;116) for holding the needle coming into contact with template, suspension system for resilient mounting of needle holder into body (12;112;114) and allowing one progressive degree of freedom relatively to body and two rotary degrees of freedom of needle holder relatively to body, and sensor (60;160) for determining shift between body and needle holder. Sensor has first capacity element (62,66;166), mounted on the body and second capacity element (64;164), mounted on needle holder, with possible combined operation with first capacity element and with possible movement relatively to first capacity element. Suspension system has resilient element or elements, to allow aforementioned progressive degree of freedom and additional resilient element or element, to allow aforementioned rotary degrees of freedom. Sensor (60,160) for determining shift between body and needle holder has first sensitive element (62,66;166), connected to body and second sensitive element (64;164), connected to needle holder, while first and second sensitive elements may operate together, move relatively one another and be represented by at least two practically coaxial pipes.

EFFECT: increased efficiency.
