Title
(EN) THREE-DIMENSIONAL MEASUREMENT UNIT AND POSITION INDICATOR
(FR) DISPOSITIF DE MESURE TRIDIMENSIONNELLE ET INDICATEUR DE POSITION TRIDIMENSIONNELLE
Abstract
(EN)
A 3-D translation and rotation measurement unit and position indicator using linear motion sensors only. The measurement unit comprises at least four linear motion sensors (10, 11, 12, 13; 20, 21, 22, 23, 24, 25) as defined, the sensors being positioned and oriented relative to each other so that one change in motion of the unit produces changing signals from at least two of the sensors and so that other changes in motion perpendicular thereto produce changing signals from sensors which include the previously unaffected sensors. The sensors are mounted on a single body (14), and the measurement unit may be connected to means to provide a 3-D position indicator.
(FR)
Dispositif de mesure tridimensionnelle de déplacement et de rotation et indicateur de position tridimensionnelle impliquant seulement l'utilisation de capteurs de mouvement linéaire. Ce dispositif comprend au moins quatre capteurs (10, 11, 12, 13; 20, 21, 22, 23, 24, 25) de mouvement linéaire, lesquels sont placés et orientés les uns par rapport aux autres de manière qu'un déplacement du dispositif produise des signaux changeants à partir d'au moins deux des capteurs et que d'autres déplacements, perpendiculaires au premier déplacement, produisent des signaux changeants à partir des capteurs, y compris à partir de ceux non concernés précédemment. Les capteurs sont montés sur un seul corps (14) et le dispositif de mesure peut être raccordé à des moyens afin de constituer un indicateur de position tridimensionnelle.
