ACCELERATION SENSOR ARRANGEMENT, SAFING ARRANGEMENT FOR AN ACTIVATION SYSTEM, ACTIVATION SYSTEM
First Claim
1. An acceleration sensor arrangement comprising in one package:
- an acceleration threshold detector for detecting acceleration and for providing an output signal having one of a first value and a second value, the output signal having the first value when the acceleration is less than a predetermined threshold, the acceleration threshold detector being arranged to switch the output signal from the first value to the second value when the acceleration reaches the predetermined threshold; and
a processor circuit for receiving the output signal from the acceleration threshold detector and for generating an event signal to trigger an event in response to the output signal switching to the second value.

Abstract
An acceleration sensor arrangement comprises, in one package, an acceleration threshold detector for detecting acceleration and for providing an output signal and a processor circuit for receiving the output signal. The acceleration threshold detector provides an output signal having a first value when the acceleration is less than a predetermined threshold and is arranged to switch the output signal from the first value to a second value when the acceleration reaches the predetermined threshold. The processor circuit generates an event signal to trigger an event, such as the closing of a safing transistor switch in an airbag system, in response to the output signal from the acceleration threshold detector switching to the second value.
