Abstract
A device is disclosed comprising: a first portion; a second portion; a hinge element between the first portion and the second portion; a magnetic sensor disposed on the first portion configured to measure an ambient magnetic field; a non-extensible element configured between the first portion and the second portion, and fixed with respect to the second portion; a magnetic element configured on a free end of the non-extensible element so that a rotation of the first portion with respect to the second portion causes relative motion between the magnetic element and the magnetic sensor, thereby causing a change in a magnetic field between the magnetic element and the magnetic sensor; wherein an angle of fold between the two portions is calculated based on the change in the magnetic field as determined by the magnetic sensor.
