This paper presents an effectively unbiased nonlinear estimation scheme which identifies tire longitudinal stiffness and effective radius using GPS and ABS wheelspeed sensors. This estimation strategy is then used to experimentally identify the longitudinal stiffness and effective radius of a summer tire and a winter tire under several different test conditions. The data clearly shows that ther...

• Objective: To measure provider adherence with the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) and assess whether adherence is associated with improved blood pressure (BP) control among low-income African-American

Presents the principles of analytical methods, environmental monitoring, biological monitoring and direct human exposure assessment of lead and cadmium. Illustrates each research area, by giving the results obtained from studies carried out in the Croatian region and performed within the Institute of Medical Research and Occupational Health in Zagreb. Also presents the results obtained for lead...

Tire Pressure Monitoring Systems represent, to the best of our knowledge, the first in-car wireless network mandated for every new automobile. The security and privacy implications of such incar wireless sensor networks are not fully understood— in particular, it is unclear whether the metal car body sufficiently shields these low-power transceivers from eavesdropping and outside interference. ...

The performance characteristics of four 24-inch wheelchair tires are considered; one pneumatic and three airless. Specifically, two new airless polyurethane foam tires (circular and tapered cross-section) were compared to both a molded polyisoprene tire and a rubber pneumatic tire. Rolling resistance, coefficient of static friction, spring rate, tire roll-off, impact absorption, wear resistance...

A tire pressure measuring system based on surface acoustic wave (SAW) sensors is presented. Since SAW sensors are powered by the energy of the RF field no battery is required, which is a major drawback of conventional systems. A successful combination of a SAW reflective delay line with a capacitive pressure sensor is shown. With a new way of matching the sensor impedance to the SAW reflector i...

-The sidewall is one of the regions where service failures occur in a pneumatic tire. Knowledge of the stresses or strains developed in the sidewall under varying service conditions is required if such pneumatic-tire failures are to be avoided. This paper describes an experimental investigation into the effect of inflation pressure, vehicle load and camber angle on the sidewall-surface strains ...

This review discusses key technologies of intelligent tires focusing on sensors and wireless data transmission. Intelligent automobile tires, which monitor their pressure, deformation, wheel loading, friction, or tread wear, are expected to improve the reliability of tires and tire control systems. However, in installing sensors in a tire, many problems have to be considered, such as compatibil...
