First Claim
Patent Images
1. An impulse sensor, comprising:
- a long elastic structure comprising a material to be deformed according to an impulse;
a cable insertion hole formed in the elastic structure; and
a cable inserted through the cable insertion hole, the cable being operable to cause a variation in propagation energy due to its deformation, wherein a distance from a central line of the cable to an outer surface of the elastic structure is varied in a longitudinal direction of the elastic structure.
