US12782098 - Autonomous pyrotechnic igniter simulator

The pyrotechnic igniter simulator ( 1 ) has a detection element ( 5 ) that is able to detect at least one ignition pulse, a microcontroller ( 6 ) that is able to determine characteristics of the ignition pulse detected by the detection element ( 5 ) and to control an impedance block ( 7 ) depending on these characteristics, the microcontroller ( 6 ) being able to be configured remotely, and the impedance block ( 7 ) being able to be simulated at one of two different impedance values depending on these characteristics, one of the impedance values, referred to as the high value, simulating activation of the igniter in response to the detected ignition pulse, and the other impedance value, referred to as the low value, simulating non-activation of the igniter in response to the detected ignition pulse, the resulting simulator ( 1 ) being autonomous and especially proficient.

pyrotechnicssimulatorelectricalfiringdevice

The autonomous pyrotechnic igniter simulator detects ignition pulses and utilizes a microcontroller to control an impedance block that simulates either activation or non-activation of an igniter based on the pulse characteristics. This device can be remotely configured and includes a charging element to power its electronic components by recovering energy from the received firing pulses.
