Sensor system for determining relative displacement of an object using a flexible retractable activation member
First Claim
1. A sensor system for detecting a movement of a first portion of a structure relative to a second portion of the structure, the sensor system comprising:
- a flexible retractable member having a first end pivotably attached to a first portion of the structure and a second end driven by the second portion of the structure, wherein the flexible retractable member is wound and unwound about the pivotal attachment upon relative movement of the first end with respect to the second end, the flexible retractable member has at least one activation portion and at least one deactivation portion, and the at least one activation zone is a longitudinally extending slot; and
a sensor for detecting the at least one activation portion and the at least one deactivation portion for determining at least one position of the second portion relative to the first portion of the structure.

Abstract
A sensor system for detecting a movement of a first portion of a structure relative to a second portion of the structure is disclosed. The sensor system has a flexible retractable member having a first end pivotably attached to one of the first portion of the structure and the second portion of the structure and a second end driven by the other of the first portion of the structure and the second portion of the structure. The flexible retractable member is wound and unwound about the pivotal attachment upon relative movement of the first end with respect to the second end. Further, the flexible retractable member has at least one activation portion and at least one deactivation portion. The sensor system further includes a sensor for detecting the at least one activation portion and the at least one deactivation portion for determining at least one position of the second portion relative to the first portion of the structure.
