Abstract

See full text

A sensing system includes an off-axis coil in which wire is wound in loops about a roll axis and at an angle to the roll axis. In particular, the loops define respective areas that have a normal direction at a non-zero angle relative to the roll axis. A field generator can generate a variable magnetic field through the coil, and sensor logic can be coupled to the coil and configured to determine a measurement of a roll angle of the coil about the first axis using an electrical signal induced in the coil.
