1. An apparatus for monitoring a tire pressurization state in a tire, the apparatus comprising:
- a magneto-mechanical pressure sensor being in or on the tire;
an electromagnetic excitation system for interrogating said magneto-mechanical pressure sensor;
a receiver for receiving information from said electro magnetic excitation system; and
a data interpretation system for translating said received information into the tire pressurization state, said data interpretation system being connected to a display to communicate the tire pressurization state to an operator.

Abstract
An apparatus for monitoring tire pressurization state in a tire has a magneto-mechanical pressure sensor in or on the tire and an electromagnetic excitation system. The electromagnetic excitation system is for interrogating the magneto-mechanical pressure sensor. The apparatus also has a receiver. The receiver is for receiving information from the electromagnetic excitation system. The apparatus also has a data interpretation system for translating the received information into the tire pressurization state. The data interpretation system is connected to a display. The display communicates the tire pressurization state to an operator.

8. An apparatus for monitoring a tire pressurization state in a tire, the apparatus comprising:
-
a magneto-mechanical pressure sensor having a linear motion mechanical sensing component, a magnetically hard element and a magnetostrictive element, and a member in said magneto-mechanical pressure sensor, wherein said member toggles at a predetermined pressure differential from a first position to a second position, wherein said member allows said magnetostrictive element to move relative to said magnetically hard element at said first position, and said member changes a characteristic resonance of at least one of said magnetostrictive element and said magnetically hard element at a second position by a manner being selected from the group consisting of touching and preventing said magnetostrictive element from resonating relative to said magnetically hard element, changing a proximity of said magnetostrictive element relative to said magnetically hard element, changing a proximity of said magnetically hard element relative to said magnetostrictive element, dampening a vibration of said magnetically hard element, dampening a vibration of said magnetostrictive element, and any combinations thereof; an electromagnetic excitation system for interrogating said magneto-mechanical pressure sensor; a receiver for receiving information from said electro magnetic excitation system; and a data interpretation system for translating said received information into the tire pressurization state, said data interpretation system being connected to a display to communicate the tire pressurization state to an operator. - View Dependent Claims (9, 10, 11)
