Abstract
Abstract An apparatus and method for actuating a safety system for protecting an occupant of a motor vehicle measures the acceleration of the vehicle with a first sensor along a first axis oriented substantially parallel to the forward direction of motion of the vehicle. The acceleration of the vehicle is also measured with a second sensor along a second axis oriented at an angle relative to the first axis. The acceleration signal generated by the first sensor is evaluated by an analog processor and the acceleration signal generated by the second sensor is evaluated by a digital processor. The safety system is then actuated based upon both the analog and digital evaluations.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
124 words
An electronic system for activating a vehicle rider protection apparatus comprising: an acceleration sensor which detects the acceleration of the vehicle and produces an electrical acceleration signal indicative of the detected acceleration; digital signal processing means which detects an event of collision of the vehicle based on the acceleration signal and produces a first detection signal in response to the detection of collision; a first analog signal processing means which detects an event of collision of the vehicle based on the acceleration signal and produces a second detection signal in response to the detection of collision; and first circuit means for producing a trigger signal for activating the vehicle rider protection apparatus in response to only one of the first and second detection signals.
Claim 2
Dependent Claim
124 words
An electronic system for activating a vehicle rider protection apparatus comprising: an acceleration sensor which detects the acceleration of the vehicle and produces an electrical acceleration signal indicative of the detected acceleration; digital signal processing means which detects an event of collision of the vehicle based on the acceleration signal and produces a first detection signal in response to the detection of collision; a first analog signal processing means which detects an event of collision of the vehicle based on the acceleration signal and produces a second detection signal in response to the detection of collision; and first circuit means for producing a trigger signal for activating the vehicle rider protection apparatus in response to only one of the first and second detection signals.
Claim 3
Dependent Claim
110 words
An electronic system for activating a vehicle rider protection apparatus, comprising: an acceleration sensor detecting the acceleration of a vehicle and producing an acceleration signal indicative of the detected acceleration; a digital signal processor detecting collision of the vehicle based on the acceleration signal and producing a first detection signal in response to the detection of collision; an analog signal processor detecting collision of the vehicle based on the acceleration signal and producing a second detection signal in response to the detection of collision; a first circuit producing a trigger signal to activate the vehicle rider protection apparatus in response to only one of the first and second detection signals.
Claim 4
Dependent Claim
110 words
An electronic system for activating a vehicle rider protection apparatus, comprising: an acceleration sensor detecting the acceleration of a vehicle and producing an acceleration signal indicative of the detected acceleration; a digital signal processor detecting collision of the vehicle based on the acceleration signal and producing a first detection signal in response to the detection of collision; an analog signal processor detecting collision of the vehicle based on the acceleration signal and producing a second detection signal in response to the detection of collision; a first circuit producing a trigger signal to activate the vehicle rider protection apparatus in response to only one of the first and second detection signals.
