The present invention relates to a piezoelectric sensor () comprising a piezoelectric material () interposed between a first () and a second () electric contact element. The first electric contact element () comprises at least two sensing areas () spatially separated along a sensing direction. It also describes a sensor node that includes the piezoelectric sensor, a system and a method for monitoring the integrity of a structure using said piezoelectric sensor.

Piezoelectric sensor, system and method for monitoring the integrity of structures

A system for correction of the fuel injection time control upon variation in altitude, for a heat engine having an electronic fuel injection system, and having means for substantially detecting the value of the external atmospheric pressure and the consequently correcting the value of induction air pressure utilized by a central processing unit of the injection system for calculating the injection time.

System for correction of the fuel injection time, upon variations in

A system for limiting the maximum speed of an internal combustion engine comprising an electronic injection system, which system comprises first means for detecting when the speed of the engine exceeds a first given threshold value, and for consequently disabling fuel supply to the injectors, and second means for determining whether the speed of the engine exceeds a second given threshold value higher than the first threshold value, and for consequently maintaining disabled or enabling fuel supply.
