  • the piezo electric shock sensor (14) By rotating and placing the piezo electric shock sensor (14) on the PCB at an angle of which the sensor sensing axis is inconsistent with the impact axis, the sensitivity of the sensor is reduced, thereby ensuring a more accurate reading of the firearm's (90) firing and eliminated false detections of possible vibrations detected by the shock sensor (14). Owing to the firearm's firing being an explosion initiated mechanical movement, it contains more than sufficient energy to trigger the piezoelectric shock sensor (14). As a result, the sensor may be rotated to passively attenuate its response to reject common events like dropping on the floor, slide release, hitting pistol on hard surface etc. while preserving enough sensor dynamic range to capture real shot-events. Such placement of the piezo electric shock sensor (14) deliberately differs from and goes against the sensor manufacturer's suggested placement.

  • the device, system and method as hereinbefore described provides for improved robustness and accuracy over traditional mechanisms.
  • devices that use only a single digital accelerometer may achieve an accuracy of about 70%
  • the combination of an analogue shock sensor and a digital accelerometer of the present device and system may increase the accuracy to over 90%.
  • the present device is not limited by the traditionally weak computational power of its semiconductor devices and provides for broader dynamics by passively attenuating the high g-force signal on a more appropriate impact axis in use.
  • the combination of analogue sensor and digital accelerometer, the pre-defined patterns, and the specific weighting coefficients as hereinbefore described system robustness and an accuracy of over 99% may be achieved by the device and system in use.
