A measurement device can detect a degree of bending of a linear body with a sensor when compressive force in a direction of longitudinal axis is applied to the linear body as a result of contact of a tip end of the linear body with an obstacle. Then, the detected degree of bending of the linear body...http://www.google.de/patents/US7984659?utm_source=gb-gplus-sharePatent US7984659 - Device and method for measuring compressive force of flexible linear body
