Abstract:
A parking management system (100) is provided. The parking management system manages at least one parking area (115) and is adapted to provide parking management services to vehicle drivers looking for parking places. The parking management system includes a sensor system (125) adapted to monitor the at least one parking area for providing occupancy indications about the occupancy of the parking area and a data gathering and communication network (130), adapted to collect the occupancy indications from the sensor system and to derive therefrom indications about the available parking spaces in the at least one parking area. The parking management system further includes a service management center (135) adapted to receive the indications about the available parking spaces in the at least one parking area and receive from the vehicle driver a request of availability of parking places. The request includes data related to a size of the requested parking place. Based on the data related to the size of the requested parking place and the indications about the available parking spaces, the service management system notifies to the vehicle driver the availability of a parking place of the requested size.

Abstract:
A method wherein a brake element (1) is sensorized by means of at least one piezoceramic sensor (15) arranged between a metallic support element (11) and a block (14) of friction material of a brake element, said sensor being completely embedded within the block of friction material; an electrical voltage signal (ST) generated by at least one piezoceramic sensor, without the need for an electrical power supply, is picked up by an electrical circuit (18) which is integrated into the metallic support element, and the electrical signal is processed in real time in the form of equal length of time samples per unit of time of the detected signal by successively processing in real time each sample of equal length of time sample of the signal by applying an algorithm selected from the group: a sequence of integrations of voltage values in the sample carried out in an interval of time in the order of milliseconds; FFT voltage data sample; integral of the voltage data sample.
Abstract:
The invention relates to a method and a system for sensing the velocity of a moving object. The method comprises acquiring at least two measurement signals via respectively at least two sensors spaced apart by a known distance, each of the two measurement signals being representative of a physical quantity which is measurable by the respective sensor and is subject to a change in correspondence to a passage of the moving object near the respective sensor, and calculating the velocity of the moving object as a function of at least one time derivative and at least one spatial derivative of said physical quantity derived from the two measurement signals. A system based on the above method is also disclosed.
