Shock sensor for use in helmet used by e.g. cyclist, has electronic housing providing information on location of shock derived from identity of pipes when pressure measured relative to initial pressure is increased due to shock

摘要

The sensor has a network of flexible tubes (12) filled with pressurized fluid and arranged on a part of human body to form a matrix with rows and columns. An electronic housing (16) provided with a microcontroller is connected to the network to measure pressure at an end of each pipe and compare the measured pressure value with a value of initial pressure. The electronic housing provides information on location of the shock derived from an identity of the pipes when the pressure measured relative to the initial pressure is increased due to shock.
