Abstract
Systems and methods facilitate the monitoring of tire pressure, the detection/determination of wheel speed, or a combination thereof. A system is provided comprising a hub cap, a target coupled to the hub cap, and at least two displacement sensors configured to measure a displacement between each displacement sensor and the target. The target has a variable thickness, and the target comprises a hollow vessel in fluid communication with a tire.
Claims8
A system comprising:
- a hub cap;
- a target coupled to the hub cap;
- and
- a displacement sensor configured to measure a displacement between the displacement sensor and the target,
- wherein the target has a variable thickness, and
- wherein the displacement between the displacement sensor and the target is configured to vary as the hub cap rotates.
The system of claim l, wherein the displacement between the displacement sensor and the target continuously increases in response to the huh cap rotating from about 0 degrees to about 180 degrees, and wherein the displacement between the displacement sensor and the target continuously decreases in response to the hub cap rotating from about 180 degrees to about 359 degrees.
