Patent Images
1. A vehicle system comprising:
- a base;
a seat rotatably disposed on the base;
a magnet generating a magnetic field; and
a sensor programmed to measure an angular displacement of the seat relative to the base based at least in part on an orientation of the magnetic field generated by the magnet, wherein rotation of the seat changes a strength of the magnetic field and wherein the sensor is programmed to detect whether the seat is rotating based at least in part on a change in the strength of the magnetic field.

Abstract
A vehicle system includes a base, a seat rotatably disposed on the base, a magnet generating a magnetic field, and a sensor. The sensor is programmed to measure an angular displacement of the seat relative to the base based at least in part on an orientation of the magnetic field generated by the magnet.

7. A vehicle system comprising:
-
a base; a seat rotatably disposed on the base; a circle gear disposed on the seat and configured to rotate in accordance with rotation of the seat; a magnet generating a magnetic field and spaced from the circle gear; and a sensor programmed to measure an angular displacement of the seat relative to the base based at least in part on the magnetic field generated by the magnet relative to circle gear wherein rotation of the circle gear changes a strength of the magnetic field and wherein the sensor is programmed to detect whether the circle gear is rotating based at least in part on a change in the strength of the magnetic field. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A vehicle system comprising:
-
a base; a seat rotatably disposed on the base; a circle gear disposed on the seat and configured to rotate in accordance with rotation of the seat, wherein the circle gear includes a plurality of teeth and a plurality of gaps, wherein each gap is disposed between two teeth and defined by a bottomland; a light emitting device configured to generate light; and a sensor programmed to measure an angular displacement of the seat relative to the base based at least in part on the light generated by the light emitting device relative to a circle gear, wherein the sensor is configured to receive the light generated by the light emitting device when one of the plurality of gaps is between the light emitting device and the sensor and wherein at least one of the plurality of teeth block the light from reaching the sensor when the at least one of the plurality of teeth is between the light emitting device and the sensor. - View Dependent Claims (15, 16, 17, 18, 19)
