Abstract
An acceleration responsive circuit is provided including an electronic accelerometer having an analog electrical signal output representative of detected acceleration which signal is inputted into an analog/digital converter to provide a digital signal in response to the accelerometer output together with an integrator for integrating the digital signal and, in the event a threshold acceleration has been exceeded, an operating circuit is energized to activate selected equipment such as, for example, the inflator for an airbag.
