This article presents an overview on the state of the art of Tyre Pressure Monitoring System related technologies. This includes examining the latest pressure sensing methods and comparing different types of pressure transducers, particularly their power consumption and measuring range. Having the aim of this research to investigate possible means to obtain a tyre condition monitoring system (T...

Military fighter pilots have to function in environments that unavoidably have an effect on both production and reception of speech. Speech production is affected by for example g-forces, positive pressure breathing (PBG), background noise and workload. This can have an effect on the understandability of speech, which in turn can affect flight safety. This study seeks to analyse the changes in ...

The MEMS pressure sensor has been introduced and presented in this paper. The types of pressure sensor and its theory of operation are also included. The latest MEMS technology, the fabrication processes of pressure sensor are explored and discussed. Besides, various device applications of pressure sensor such as tire pressure-monitoring system, diesel particulate filter and others are explaine...

in this study, a cylindrical bolling probe was developed and evaluated for measuring stress in soil under tire traffic. the probe consists of a silicon rubber head for sensing the soil stress, a pvc tube for transferring the liquid pressure, a digital pressure sensor and a syringe for filling the probe with water and adjusting the initial inclusion pressure. a tank with pressurized air was used...

This paper is focused on a novel design of stepped diaphragm for MEMS capacitive pressure sensor used in tire pressure monitoring system. The structure of sensor diaphragm plays a key role for determining the sensitivity of the sensor and the non-linearity of the output.First the structures of two capacitive pressure sensors with clamped square flatdiaphragms, with different thicknesses are inv...

A nonlinear model consisting “yaw, roll, longitudinal, lateral and pitch” has been developed in which, tire and suspension characteristics have been considered. Tire model is based on the elliptic concept and tire Calspan data. According to this tire model, cornering force and aligning moment are computed as a function of slip and camber (inclination) angles, normal load, tire adhesion characte...

Tire pressure has a significant influence on the driving safety of road vehicles; therefore, it is mandatory in many countries to equip all new vehicles with tire monitoring system (TPMS). There are two types TPMSs use: direct TPMS (dTPMS) and indirect (iTPMS), both which have made improvement last decade. The most accurate iTPMS methods used commercial apply Fourier transform wheel speed senso...
