Tire monitoring apparatus, system and method of using the same

摘要

A system and method for measuring, recording and reporting vehicle tire temperatures and/or pressures. In one aspect, a sensing device including a convex protective vessel, with pressure and/or temperature sensors enclosed therein. The sensing device is dropped freely within the interior of a tire prior to rim mounting. A movement sensor can also be included in the sensing device. The protective vessel, including all sensors, is not attached or connected in any way to the vehicle tire, rim, or valve stem such that the sensing device is independent of the vehicle tire, rim, and valve stem, and moves freely within the interior of the tire. A balancing set including a dummy device, substantially equal in weight to a sensing device, and means for connecting the dummy device to the sensing device at 180 degrees separation around the tire may also be employed.

主权项

1. A sensing apparatus for measuring a pressure and/or a temperature of gases in an interior of a tire, comprising:
a protective vessel configured to move freely within the interior of the tire; pressure and/or temperature sensors enclosed within the protective vessel and configured to sense a current pressure and/or a current temperature of the gases in the interior of the tire; a transmitter configured to wirelessly convey to outside the tire data indicative of the current pressure and/or current temperature of gases in the interior of the tire; and wherein the protective vessel is configured with a porosity and elasticity allowing the pressure and/or the temperature conditions in the interior of the tire to freely penetrate the protective vessel and communicate directly with the pressure and/or the temperature sensors.
