Abstract

The present invention discloses a technique for measuring shape change, determining location of collision and providing real time data acquisition. A helical multicore fiber optic sensor is integrated around a gantry AGV foot bottom contour shape along with permanently fixed deformable material. Measuring is performed through micro strains at some distant of resolution. Optical fiber domain reflectometry and optical distribution sensor interrogator are integrated with gantry AGV electrical mechanical hardware architecture. Optical fiber domain reflectometry mechanism is used to detect a collision. Actual shape of fiber optic sensor cable is changed when collision happens due to operators and anesthetist.

GANTRY AUTOMATIC GUIDED VEHICLE FOOT COLLISION DETECTION

FIELD OF INVENTION

The present invention relates generally to a gantry automatic guided vehicle (AGV) foot bottom cover, and more particularly to a technique for detecting gantry AGV foot bottom cover collisions.

BACKGROUND OF THE INVENTION

Generally, gantry AGV foot-bottom mayser cover gets unclipped and includes collision detection logs. Anesthetist comes in contact with bottom cover mayser due to workflow. Such contact results in collisions, stoppage of gantry, cleanability and sterility issues in real use scenario.

A conventional technique relates to a load detecting sensor. The load detecting sensor includes a first member, a second member and an optical fiber. The first member has a groove which has a bottom portion and a column portion. The second member covers the groove of the first member to form surrounded space. The optical fiber is arranged in the surrounded space. The surrounded space is deformable when load is applied to one of the first and the second members. The deformation of the optical fiber and the deformation of the surrounded space occur when load is applied to one of the first and the second members.

Another conventional technique relates to a collision detection device. The collision detection device is provided with a load detection member for detecting collision load during a collision. The collision detection device is provided with a mold member. The mold member is molded to be integral with the load detection member. The mold member covers a surface of a collision side of the load detection member. Such coverage absorbs a part of impact energy in the collision by a resilient deformation of the mold member.

However the conventional technique does not measure the shape change in three dimensional grid co-ordinate system of the collision irrespective of load and do not search the location of collision. The conventional technique does not provide real time three dimensional data logging for analysis of collision in cath lab/clinical environment for the workflow and layout study.

Hence, there exists a need in the art for an improved gantry AGV collision detection system.
