Abstract:
1. A method for detecting impacts through a detection device comprising an integrated microcontroller ( 1 ) which includes an RFID interface ( 101 ) and a non-volatile memory ( 201 ), said integrated microcontroller ( 1 ) being interfaced with at least one suitable sensing means ( 2 ) through a suitable digital interface ( 102 ), said integrated microcontroller ( 1 ) being provided with a power management logic ( 301 ) to manage operation modes of said detection device, the power consumption of said sensing means ( 2 ) being managed by said power management logic ( 301 ), said method comprising the steps of: acquiring data from said sensing means ( 2 ) over a given time frame, storing said data in said non-volatile memory ( 201 ) of said integrated microcontroller ( 1 ), and setting said integrated microcontroller ( 1 ) in a power saving mode, wherein said sensing means comprise three sensors ( 212 , 222 , 232 ) connected to a controller ( 302 ) provided with a memory register ( 312 ) to store detection threshold values; three memory registers ( 412 , 422 , 432 ) to store detected data and an I/O interface ( 502 ) to communicate with said digital interface ( 102 ) of said integrated microcontroller ( 1 ); and wherein data detecting step comprises detecting data in time frames Δt which are small compared to an activation time frame of said sensing means ( 2 ), and logging said data in suitable memory registers ( 412 , 422 , 432 ).
