Apparatus and Method for Magnetic Sensor Based Surface Shape Analysis Spatial Positioning in a Uniform Magnetic Field
First Claim
1. A device, comprising:
- a flexible substrate supporting an array of magnetic sensors exposed to a uniform external magnetic field; and
one or more controllers to receive magnetic sensor signals from the magnetic sensors, wherein the one or more controllers collect reference magnetic sensor signals when the flexible substrate is aligned with the uniform external magnetic field, first polarity magnetic sensor signals in response to deformation of the flexible substrate in a first direction and second polarity magnetic sensor signals in response to deformation of the flexible substrate in a second direction, such that the magnetic sensor signals establish a profile of the orientation of the flexible substrate with respect to the uniform external magnetic field.

Abstract
A device has a flexible substrate supporting an array of magnetic sensors exposed to a uniform external magnetic field. One or more controllers receive magnetic sensor signals from the magnetic sensors. The one or more controllers collect reference magnetic sensor signals when the flexible substrate is aligned with the uniform external magnetic field. The one or more controllers collect first polarity magnetic sensor signals in response to deformation of the flexible substrate in a first direction. The one or more controllers collect second polarity magnetic sensor signals in response to deformation of the flexible substrate in a second direction. The magnetic sensor signals establish a profile of the orientation of the flexible substrate with respect to the uniform external magnetic field.
